For more information, Linux contains a * reference implementation for guest OSes (arch/xen/kernel/grant_table.c). * * NB. WMB is a no-op on current-generation x86 processors.

Write memory barrier (WMB). * 4. Write ent->flags, inc. valid type. * * Invalidating an unused GTF_permit_access entry: * 1. flags = ent->flags. * 2.

No need for WMB as reuse of entry is control-dependent on success of * step 3, and all architectures guarantee ordering of ctrl-dep writes. * * Invalidating an in-use GTF_permit_access entry: * This cannot be done directly.

If this is possible at the moment of error, * then frontend goes into the XenbusStateInitialising state and is ready for * new connection with backend. If the virtualized device is still in use and * cannot be removed, then frontend goes into the XenbusStateReconfiguring state * until either the virtualized device is removed or backend initiates a new * connection. On the virtualized device removal frontend goes into the * XenbusStateInitialising state. * * Note on XenbusStateReconfiguring state of the frontend: if backend has * unrecoverable errors then frontend cannot send requests to the backend * and thus cannot provide functionality of the virtualized device anymore. * After backend is back to normal the virtualized device may still hold some * state: configuration in use, allocated buffers, client application state etc. * In most cases, this will require frontend to implement complex recovery * reconnect logic. Instead, by going into XenbusStateReconfiguring state, * frontend will make sure no new clients of the virtualized device are * accepted, allow existing client(s) to exit gracefully by signaling error * state etc. * Once all the clients are gone frontend can reinitialize the virtualized * device and get into XenbusStateInitialising state again signaling the * backend that a new connection can be made. * * There are multiple conditions possible under which frontend will go from * XenbusStateReconfiguring into XenbusStateInitialising, some of them are OS * specific. For example: * 1. The underlying OS framework may provide callbacks to signal that the last * client of the virtualized device has gone and the device can be removed * 2. Frontend can schedule a deferred work (timer/tasklet/workqueue) * to periodically check if this is the right time to re-try removal of * the virtualized device. * 3.

For example, card may define number of channels to be * in [1; 8] range, and some particular stream may be limited to [1; 2] only. * The rule is that the underlying layer must be a subset of the upper layer * range. * * channels-min * Values: <uint8_t> * * The minimum amount of channels that is supported, [1; channels-max]. * Optional, if not set or omitted a value of 1 is used. * * channels-max * Values: <uint8_t> * * The maximum amount of channels that is supported. * Must be at least <channels-min>. * * sample-rates * Values: <list of uint32_t> * * List of supported sample rates separated by XENSND_LIST_SEPARATOR. * Sample rates are expressed as a list of decimal values w/o any * ordering requirement. * * sample-formats * Values: <list of XENSND_PCM_FORMAT_XXX_STR> * * List of supported sample formats separated by XENSND_LIST_SEPARATOR. * Items must not exceed XENSND_SAMPLE_FORMAT_MAX_LEN length. * * buffer-size * Values: <uint32_t> * * The maximum size in octets of the buffer to allocate per stream. * *----------------------- Virtual sound card settings ------------------------- * short-name * Values: <char[32]> * * Short name of the virtual sound card. Optional. * * long-name * Values: <char[80]> * * Long name of the virtual sound card. Optional. * *----------------------------- Device settings ------------------------------- * name * Values: <char[80]> * * Name of the sound device within the virtual sound card. Optional. * *----------------------------- Stream settings ------------------------------- * * type * Values: "p", "c" * * Stream type: "p" - playback stream, "c" - capture stream * * If both capture and playback are needed then two streams need to be * defined under the same device. * * unique-id * Values: <string> * * After stream initialization it is assigned a unique ID, so every * stream of the frontend can be identified by the backend by this ID. * This can be UUID or such. * *-------------------- Stream Request Transport Parameters -------------------- * * event-channel * Values: <uint32_t> * * The identifier of the Xen event channel used to signal activity * in the ring buffer. * * ring-ref * Values: <uint32_t> * * The Xen grant reference granting permission for the backend to map * a sole page in a single page sized ring buffer. * *--------------------- Stream Event Transport Parameters --------------------- * * This communication path is used to deliver asynchronous events from backend * to frontend, set up per stream. * * evt-event-channel * Values: <uint32_t> * * The identifier of the Xen event channel used to signal activity * in the ring buffer. * * evt-ring-ref * Values: <uint32_t> * * The Xen grant reference granting permission for the backend to map * a sole page in a single page sized ring buffer. * ****************************************************************************** * STATE DIAGRAMS ****************************************************************************** * * Tool stack creates front and back state nodes with initial state * XenbusStateInitialising. * Tool stack creates and sets up frontend sound configuration nodes per domain. * * Front Back * ================================= ===================================== * XenbusStateInitialising XenbusStateInitialising * o Query backend device identification * data. * o Open and validate backend device. * | * | * V * XenbusStateInitWait * * o Query frontend configuration * o Allocate and initialize * event channels per configured * playback/capture stream. * o Publish transport parameters * that will be in effect during * this connection. * | * | * V * XenbusStateInitialised * * o Query frontend transport parameters. * o Connect to the event channels. * | * | * V * XenbusStateConnected * * o Create and initialize OS * virtual sound device instances * as per configuration. * | * | * V * XenbusStateConnected * * XenbusStateUnknown * XenbusStateClosed * XenbusStateClosing * o Remove virtual sound device * o Remove event channels * | * | * V * XenbusStateClosed * *------------------------------- Recovery flow ------------------------------- * * In case of frontend unrecoverable errors backend handles that as * if frontend goes into the XenbusStateClosed state. * * In case of backend unrecoverable errors frontend tries removing * the virtualized device. If this is possible at the moment of error, * then frontend goes into the XenbusStateInitialising state and is ready for * new connection with backend. If the virtualized device is still in use and * cannot be removed, then frontend goes into the XenbusStateReconfiguring state * until either the virtualized device removed or backend initiates a new * connection. On the virtualized device removal frontend goes into the * XenbusStateInitialising state. * * Note on XenbusStateReconfiguring state of the frontend: if backend has * unrecoverable errors then frontend cannot send requests to the backend * and thus cannot provide functionality of the virtualized device anymore. * After backend is back to normal the virtualized device may still hold some * state: configuration in use, allocated buffers, client application state etc. * So, in most cases, this will require frontend to implement complex recovery * reconnect logic. Instead, by going into XenbusStateReconfiguring state, * frontend will make sure no new clients of the virtualized device are * accepted, allow existing client(s) to exit gracefully by signaling error * state etc. * Once all the clients are gone frontend can reinitialize the virtualized * device and get into XenbusStateInitialising state again signaling the * backend that a new connection can be made. * * There are multiple conditions possible under which frontend will go from * XenbusStateReconfiguring into XenbusStateInitialising, some of them are OS * specific. For example: * 1. The underlying OS framework may provide callbacks to signal that the last * client of the virtualized device has gone and the device can be removed * 2. Frontend can schedule a deferred work (timer/tasklet/workqueue) * to periodically check if this is the right time to re-try removal of * the virtualized device. * 3. By any other means. * ****************************************************************************** * PCM FORMATS ****************************************************************************** * *

The * pages that make up a pagetable must be mapped read-only in the guest. * This prevents uncontrolled guest updates to the pagetable. Xen strictly * enforces this, and will disallow any pagetable update which will end up * mapping pagetable page RW, and will disallow using any writable page as a * pagetable. In practice it means that when constructing a page table for a * process, thread, etc, we MUST be very dilligient in following these rules: * 1). Start with top-level page (PGD or in Xen language: L4). Fill out * the entries. * 2). Keep on going, filling out the upper (PUD or L3), and middle (PMD * or L2). * 3). Start filling out the PTE table (L1) with the PTE entries. Once * done, make sure to set each of those entries to RO (so writeable bit * is unset). Once that has been completed, set the PMD (L2) for this * PTE table as RO. * 4). When completed with all of the PMD (L2) entries, and all of them have * been set to RO, make sure to set RO the PUD (L3). Do the same * operation on PGD (L4) pagetable entries that have a PUD (L3) entry. * 5). Now before you can use those pages (so setting the cr3), you MUST also * pin them so that the hypervisor can verify the entries. This is done * via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame * number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op( * MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be * issued. * For 32-bit guests, the L4 is not used (as there is less pagetables), so * instead use L3. * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE * hypercall. Also if so desired the OS can also try to write to the PTE * and be trapped by the hypervisor (as the PTE entry is RO). * * To deallocate the pages, the operations are the reverse of the steps * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the * pagetable MUST not be in use (meaning that the cr3 is not set to it). * * ptr[1:0] == MMU_MACHPHYS_UPDATE: * Updates an entry in the machine->pseudo-physical mapping table. * ptr[:2] -- Machine address within the frame whose mapping to modify. * The frame must belong to the FD, if one is specified. * val -- Value to write into the mapping entry. * * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD: * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed * with those in @val. * * @val is usually the machine frame number along with some attributes. * The attributes by default follow the architecture defined bits. Meaning that * if this is a X86_64 machine and four page table layout is used, the layout * of val is: * - 63 if set means No execute (NX) * - 46-13 the machine frame number * - 12 available for guest * - 11 available for guest * - 10 available for guest * - 9 available for guest * - 8 global * - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages) * - 6 dirty * - 5 accessed * - 4 page cached disabled * - 3 page write through * - 2 userspace accessible * - 1 writeable * - 0 present * * The one bits that does not fit with the default layout is the PAGE_PSE * also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the * HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB * (or 2MB) instead of using the PAGE_PSE bit. * * The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen * using it as the Page Attribute Table (PAT) bit - for details on it please * refer to Intel SDM 10.12. The PAT allows to set the caching attributes of * pages instead of using MTRRs. * * The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits): * PAT4 PAT0 * +-----+-----+----+----+----+-----+----+----+ * | UC | UC- | WC | WB | UC | UC- | WC | WB | <= Linux * +-----+-----+----+----+----+-----+----+----+ * | UC | UC- | WT | WB | UC | UC- | WT | WB | <= BIOS (default when machine boots) * +-----+-----+----+----+----+-----+----+----+ * | rsv | rsv | WP | WC | UC | UC- | WT | WB | <= Xen * +-----+-----+----+----+----+-----+----+----+ * * The lookup of this index table translates to looking up * Bit 7, Bit 4, and Bit 3 of val entry: * * PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3). * * If all bits are off, then we are using PAT0. If bit 3 turned on, * then we are using PAT1, if bit 3 and bit 4, then PAT2.. * * As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means * that if a guest that follows Linux's PAT setup and would like to set Write * Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is * set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the * caching as: * * WB = none (so PAT0) * WC = PWT (bit 3 on) * UC = PWT | PCD (bit 3 and 4 are on). * * To make it work with Xen, it needs to translate the WC bit as so: * * PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3 * * And to translate back it would: * * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7. */ #define MMU_NORMAL_PT_UPDATE 0 /* checked '*ptr = val'. ptr is MA. */ #define MMU_MACHPHYS_UPDATE 1 /* ptr = MA of frame to modify entry for */ #define MMU_PT_UPDATE_PRESERVE_AD 2 /* atomically: *ptr = val | (*ptr&(A|D)) */ #define MMU_PT_UPDATE_NO_TRANSLATE 3 /* checked '*ptr = val'. ptr is MA. */ /* * MMU EXTENDED OPERATIONS * * enum neg_errnoval HYPERVISOR_mmuext_op(mmuext_op_t uops[], * unsigned int count, * unsigned int *pdone, * unsigned int foreigndom) */ /* HYPERVISOR_mmuext_op() accepts a list of mmuext_op structures. * A foreigndom (FD) can be specified (or DOMID_SELF for none). * Where the FD has some effect, it is described below. * * cmd: MMUEXT_(UN)PIN_*_TABLE * mfn: Machine frame number to be (un)pinned as a p.t. page. * The frame must belong to the FD, if one is specified. * * cmd: MMUEXT_NEW_BASEPTR * mfn: Machine frame number of new page-table base to install in MMU. * * cmd: MMUEXT_NEW_USER_BASEPTR [x86/64 only] * mfn: Machine frame number of new page-table base to install in MMU * when in user space. * * cmd: MMUEXT_TLB_FLUSH_LOCAL * No additional arguments.

Let's examine * three common cases. * * Take a look at the 16 binary octets below in memory order. The msb's * are left and the lsb's are right. char b[16] is an array and b[0] is * the first octet. * * 10000000 00000000 00000000 00000000 .... 00000000 00000000 00000000 * b[0] b[1] b[2] b[3] b[13] b[14] b[15] * * Every bit is a coefficient of some power of X. We can store the bits * in every byte in little-endian order and the bytes themselves also in * little endian order. I will call this lle (little-little-endian). * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }. * This format was originally implemented in gf128mul and is used * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length). * * Another convention says: store the bits in bigendian order and the * bytes also. This is bbe (big-big-endian). Now the buffer above * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111, * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe * is partly implemented. * * Both of the above formats are easy to implement on big-endian * machines. * * XTS and EME (the latter of which is patent encumbered) use the ble * format (bits are stored in big endian order and the bytes in little * endian). The above buffer represents X^7 in this case and the * primitive polynomial is b[0] = 0x87. * * The common machine word-size is smaller than 128 bits, so to make * an efficient implementation we must split into machine word sizes. * This implementation uses 64-bit words for the moment. Machine * endianness comes into play. The lle format in relation to machine * endianness is discussed below by the original author of gf128mul Dr * Brian Gladman. * * Let's look at the bbe and ble format on a little endian machine. * * bbe on a little endian machine u32 x[4]: * * MS x[0] LS MS x[1] LS * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls * 103..96 111.104 119.112 127.120 71...64 79...72 87...80 95...88 * * MS x[2] LS MS x[3] LS * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls * 39...32 47...40 55...48 63...56 07...00 15...08 23...16 31...24 * * ble on a little endian machine * * MS x[0] LS MS x[1] LS * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls * 31...24 23...16 15...08 07...00 63...56 55...48 47...40 39...32 * * MS x[2] LS MS x[3] LS * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls * 95...88 87...80 79...72 71...64 127.120 199.112 111.104 103..96 * * Multiplications in GF(2^128) are mostly bit-shifts, so you see why * ble (and lbe also) are easier to implement on a little-endian * machine than on a big-endian machine.

No data processing happens at this point. Driver code * implementation must not use req->result. * @update: **[mandatory]** Push a chunk of data into the driver for transformation. This * function actually pushes blocks of data from upper layers into the * driver, which then passes those to the hardware as seen fit. This * function must not finalize the HASH transformation by calculating the * final message digest as this only adds more data into the * transformation. This function shall not modify the transformation * context, as this function may be called in parallel with the same * transformation object. Data processing can happen synchronously * [SHASH] or asynchronously [AHASH] at this point. Driver must not use * req->result. * @final: **[mandatory]** Retrieve result from the driver. This function finalizes the * transformation and retrieves the resulting hash from the driver and * pushes it back to upper layers. No data processing happens at this * point unless hardware requires it to finish the transformation * (then the data buffered by the device driver is processed). * @finup: **[optional]** Combination of @update and @final. This function is effectively a * combination of @update and @final calls issued in sequence. As some * hardware cannot do @update and @final separately, this callback was * added to allow such hardware to be used at least by IPsec. Data * processing can happen synchronously [SHASH] or asynchronously [AHASH] * at this point. * @digest: Combination of @init and @update and @final. This function * effectively behaves as the entire chain of operations, @init, * @update and @final issued in sequence. Just like @finup, this was * added for hardware which cannot do even the @finup, but can only do * the whole transformation in one run. Data processing can happen * synchronously [SHASH] or asynchronously [AHASH] at this point. * @setkey: Set optional key used by the hashing algorithm. Intended to push * optional key used by the hashing algorithm from upper layers into * the driver. This function can store the key in the transformation * context or can outright program it into the hardware. In the former * case, one must be careful to program the key into the hardware at * appropriate time and one must be careful that .setkey() can be * called multiple times during the existence of the transformation * object.

No data * processing happens at this point. * @export: Export partial state of the transformation. This function dumps the * entire state of the ongoing transformation into a provided block of * data so it can be @import 'ed back later on. This is useful in case * you want to save partial result of the transformation after * processing certain amount of data and reload this partial result * multiple times later on for multiple re-use. No data processing * happens at this point. Driver must not use req->result. * @import: Import partial state of the transformation.

Naturally all *skcipher* symbols must be exchanged * the *aead* pendants discussed in the following. In addition, for the AEAD * operation, the aead_request_set_ad function must be used to set the * pointer to the associated data memory location before performing the * encryption or decryption operation. In case of an encryption, the associated * data memory is filled during the encryption operation. For decryption, the * associated data memory must contain data that is used to verify the integrity * of the decrypted data. Another deviation from the asynchronous block cipher * operation is that the caller should explicitly check for -EBADMSG of the * crypto_aead_decrypt. That error indicates an authentication error, i.e. * a breach in the integrity of the message. In essence, that -EBADMSG error * code is the key bonus an AEAD cipher has over "standard" block chaining * modes. * * Memory Structure: * * The source scatterlist must contain the concatenation of * associated data || plaintext or ciphertext. * * The destination scatterlist has the same layout, except that the plaintext * (resp. ciphertext) will grow (resp. shrink) by the authentication tag size * during encryption (resp. decryption). * * In-place encryption/decryption is enabled by using the same scatterlist * pointer for both the source and destination. * * Even in the out-of-place case, space must be reserved in the destination for * the associated data, even though it won't be written to. This makes the * in-place and out-of-place cases more consistent. It is permissible for the * "destination" associated data to alias the "source" associated data. * * As with the other scatterlist crypto APIs, zero-length scatterlist elements * are not allowed in the used part of the scatterlist. Thus, if there is no * associated data, the first element must point to the plaintext/ciphertext. * * To meet the needs of IPsec, a special quirk applies to rfc4106, rfc4309, * rfc4543, and rfc7539esp ciphers. For these ciphers, the final 'ivsize' bytes * of the associated data buffer must contain a second copy of the IV. This is * in addition to the copy passed to aead_request_set_crypt().

After this device gets its regulatory * domain programmed further regulatory hints shall only be considered * for this device to enhance regulatory compliance, forcing the * device to only possibly use subsets of the original regulatory * rules.

This will * override %REGULATORY_COUNTRY_IE_FOLLOW_POWER as all country IEs will * be ignored. * @REGULATORY_ENABLE_RELAX_NO_IR: for devices that wish to allow the * NO_IR relaxation, which enables transmissions on channels on which * otherwise initiating radiation is not allowed. This will enable the * relaxations enabled under the CFG80211_REG_RELAX_NO_IR configuration * option * @REGULATORY_IGNORE_STALE_KICKOFF: the regulatory core will _not_ make sure * all interfaces on this wiphy reside on allowed channels. If this flag * is not set, upon a regdomain change, the interfaces are given a grace * period (currently 60 seconds) to disconnect or move to an allowed * channel. Interfaces on forbidden channels are forcibly disconnected. * Currently these types of interfaces are supported for enforcement: * NL80211_IFTYPE_ADHOC, NL80211_IFTYPE_STATION, NL80211_IFTYPE_AP, * NL80211_IFTYPE_AP_VLAN, NL80211_IFTYPE_MONITOR, * NL80211_IFTYPE_P2P_CLIENT, NL80211_IFTYPE_P2P_GO, * NL80211_IFTYPE_P2P_DEVICE.

Conversely, a self-managed wiphy does not share its regulatory * hints with other devices in the system. If a system contains several * devices, one or more of which are self-managed, there might be * contradictory regulatory settings between them. Usage of flag is * generally discouraged. Only use it if the FW/driver is incompatible * with non-locally originated hints. * This flag is incompatible with the flags: %REGULATORY_CUSTOM_REG, * %REGULATORY_STRICT_REG, %REGULATORY_COUNTRY_IE_FOLLOW_POWER, * %REGULATORY_COUNTRY_IE_IGNORE and %REGULATORY_DISABLE_BEACON_HINTS. * Mixing any of the above flags with this flag will result in a failure * to register the wiphy.

This happens through a number of hardware capability structs * described below. * * The fundamental structure for each device is the 'wiphy', of which each * instance describes a physical wireless device connected to the system. Each * such wiphy can have zero, one, or many virtual interfaces associated with * it, which need to be identified as such by pointing the network interface's * @ieee80211_ptr pointer to a &struct wireless_dev which further describes * the wireless part of the interface, normally this struct is embedded in the * network interface's private data area. Drivers can optionally allow creating * or destroying virtual interfaces on the fly, but without at least one or the * ability to create some the wireless device isn't useful. * * Each wiphy structure contains device capability information, and also has * a pointer to the various operations the driver offers. The definitions and * structures here describe these capabilities in detail. */ struct wiphy; /* * wireless hardware capability structures */ /** * enum ieee80211_channel_flags - channel flags * * Channel flags set by the regulatory control code. * * @IEEE80211_CHAN_DISABLED: This channel is disabled. * @IEEE80211_CHAN_NO_IR: do not initiate radiation, this includes * sending probe requests or beaconing. * @IEEE80211_CHAN_RADAR: Radar detection is required on this channel. * @IEEE80211_CHAN_NO_HT40PLUS: extension channel above this channel * is not permitted. * @IEEE80211_CHAN_NO_HT40MINUS: extension channel below this channel * is not permitted. * @IEEE80211_CHAN_NO_OFDM: OFDM is not allowed on this channel. * @IEEE80211_CHAN_NO_80MHZ: If the driver supports 80 MHz on the band, * this flag indicates that an 80 MHz channel cannot use this * channel as the control or any of the secondary channels. * This may be due to the driver or due to regulatory bandwidth * restrictions. * @IEEE80211_CHAN_NO_160MHZ: If the driver supports 160 MHz on the band, * this flag indicates that an 160 MHz channel cannot use this * channel as the control or any of the secondary channels. * This may be due to the driver or due to regulatory bandwidth * restrictions. * @IEEE80211_CHAN_INDOOR_ONLY: see %NL80211_FREQUENCY_ATTR_INDOOR_ONLY * @IEEE80211_CHAN_IR_CONCURRENT: see %NL80211_FREQUENCY_ATTR_IR_CONCURRENT * @IEEE80211_CHAN_NO_20MHZ: 20 MHz bandwidth is not permitted * on this channel. * @IEEE80211_CHAN_NO_10MHZ: 10 MHz bandwidth is not permitted * on this channel. * @IEEE80211_CHAN_NO_HE: HE operation is not permitted on this channel. * @IEEE80211_CHAN_1MHZ: 1 MHz bandwidth is permitted * on this channel. * @IEEE80211_CHAN_2MHZ: 2 MHz bandwidth is permitted * on this channel. * @IEEE80211_CHAN_4MHZ: 4 MHz bandwidth is permitted * on this channel. * @IEEE80211_CHAN_8MHZ: 8 MHz bandwidth is permitted * on this channel. * @IEEE80211_CHAN_16MHZ: 16 MHz bandwidth is permitted * on this channel. * */ enum ieee80211_channel_flags { IEEE80211_CHAN_DISABLED = 1<<0, IEEE80211_CHAN_NO_IR = 1<<1, /* hole at 1<<2 */ IEEE80211_CHAN_RADAR = 1<<3, IEEE80211_CHAN_NO_HT40PLUS = 1<<4, IEEE80211_CHAN_NO_HT40MINUS = 1<<5, IEEE80211_CHAN_NO_OFDM = 1<<6, IEEE80211_CHAN_NO_80MHZ = 1<<7, IEEE80211_CHAN_NO_160MHZ = 1<<8, IEEE80211_CHAN_INDOOR_ONLY = 1<<9, IEEE80211_CHAN_IR_CONCURRENT = 1<<10, IEEE80211_CHAN_NO_20MHZ = 1<<11, IEEE80211_CHAN_NO_10MHZ = 1<<12, IEEE80211_CHAN_NO_HE = 1<<13, IEEE80211_CHAN_1MHZ = 1<<14, IEEE80211_CHAN_2MHZ = 1<<15, IEEE80211_CHAN_4MHZ = 1<<16, IEEE80211_CHAN_8MHZ = 1<<17, IEEE80211_CHAN_16MHZ = 1<<18, }; #define IEEE80211_CHAN_NO_HT40 \ (IEEE80211_CHAN_NO_HT40PLUS | IEEE80211_CHAN_NO_HT40MINUS) #define IEEE80211_DFS_MIN_CAC_TIME_MS 60000 #define IEEE80211_DFS_MIN_NOP_TIME_MS (30 * 60 * 1000) /** * struct ieee80211_channel - channel definition * * This structure describes a single channel for use * with cfg80211. * * @center_freq: center frequency in MHz * @freq_offset: offset from @center_freq, in KHz * @hw_value: hardware-specific value for the channel * @flags: channel flags from &enum ieee80211_channel_flags. * @orig_flags: channel flags at registration time, used by regulatory * code to support devices with additional restrictions * @band: band this channel belongs to. * @max_antenna_gain: maximum antenna gain in dBi * @max_power: maximum transmission power (in dBm) * @max_reg_power: maximum regulatory transmission power (in dBm) * @beacon_found: helper to regulatory code to indicate when a beacon * has been found on this channel.

When the driver is * ready on the requested channel, it must indicate this with an event * notification by calling cfg80211_ready_on_channel(). * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. * This allows the operation to be terminated prior to timeout based on * the duration value. * @mgmt_tx: Transmit a management frame. * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management * frame on another channel * * @testmode_cmd: run a test mode command; @wdev may be %NULL * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be * used by the function, but 0 and 1 must not be touched. Additionally, * return error codes other than -ENOBUFS and -ENOENT will terminate the * dump and return to userspace with an error, so be careful. If any data * was passed in from userspace then the data/len arguments will be present * and point to the data contained in %NL80211_ATTR_TESTDATA. * * @set_bitrate_mask: set the bitrate mask configuration * * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac * devices running firmwares capable of generating the (re) association * RSN IE. It allows for faster roaming between WPA2 BSSIDs. * @del_pmksa: Delete a cached PMKID. * @flush_pmksa: Flush all cached PMKIDs. * @set_power_mgmt: Configure WLAN power management. A timeout value of -1 * allows the driver to adjust the dynamic ps timeout value. * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold. * After configuration, the driver should (soon) send an event indicating * the current level is above/below the configured threshold; this may * need some care when the configuration is changed (without first being * disabled.) * @set_cqm_rssi_range_config: Configure two RSSI thresholds in the * connection quality monitor. An event is to be sent only when the * signal level is found to be outside the two values. The driver should * set %NL80211_EXT_FEATURE_CQM_RSSI_LIST if this method is implemented. * If it is provided then there's no point providing @set_cqm_rssi_config. * @set_cqm_txe_config: Configure connection quality monitor TX error * thresholds. * @sched_scan_start: Tell the driver to start a scheduled scan. * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan with * given request id. This call must stop the scheduled scan and be ready * for starting a new one before it returns, i.e. @sched_scan_start may be * called immediately after that again and should not fail in that case. * The driver should not call cfg80211_sched_scan_stopped() for a requested * stop (when this method returns 0). * * @update_mgmt_frame_registrations: Notify the driver that management frame * registrations were updated. The callback is allowed to sleep. * * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may * reject TX/RX mask combinations they cannot support by returning -EINVAL * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). * * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). * * @tdls_mgmt: Transmit a TDLS management frame. * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup). * * @probe_client: probe an associated client, must return a cookie that it * later passes to cfg80211_probe_status(). * * @set_noack_map: Set the NoAck Map for the TIDs. * * @get_channel: Get the current operating channel for the virtual interface. * For monitor interfaces, it should return %NULL unless there's a single * current monitoring channel. * * @start_p2p_device: Start the given P2P device. * @stop_p2p_device: Stop the given P2P device. * * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode. * Parameters include ACL policy, an array of MAC address of stations * and the number of MAC addresses. If there is already a list in driver * this new list replaces the existing one. Driver has to clear its ACL * when number of MAC addresses entries is passed as 0. Drivers which * advertise the support for MAC based ACL have to implement this callback. * * @start_radar_detection: Start radar detection in the driver. * * @end_cac: End running CAC, probably because a related CAC * was finished on another phy. * * @update_ft_ies: Provide updated Fast BSS Transition information to the * driver. If the SME is in the driver/firmware, this information can be * used in building Authentication and Reassociation Request frames. * * @crit_proto_start: Indicates a critical protocol needs more link reliability * for a given duration (milliseconds). The protocol is provided so the * driver can take the most appropriate actions. * @crit_proto_stop: Indicates critical protocol no longer needs increased link * reliability. This operation can not fail. * @set_coalesce: Set coalesce parameters. * * @channel_switch: initiate channel-switch procedure (with CSA). Driver is * responsible for veryfing if the switch is possible. Since this is * inherently tricky driver may decide to disconnect an interface later * with cfg80211_stop_iface(). This doesn't mean driver can accept * everything. It should do it's best to verify requests and reject them * as soon as possible. * * @set_qos_map: Set QoS mapping information to the driver * * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the * given interface This is used e.g. for dynamic HT 20/40 MHz channel width * changes during the lifetime of the BSS. * * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device * with the given parameters; action frame exchange has been handled by * userspace so this just has to modify the TX path to take the TS into * account. * If the admitted time is 0 just validate the parameters to make sure * the session can be created at all; it is valid to just always return * success for that but that may result in inefficient behaviour (handshake * with the peer followed by immediate teardown when the addition is later * rejected) * @del_tx_ts: remove an existing TX TS * * @join_ocb: join the OCB network with the specified parameters * (invoked with the wireless_dev mutex held) * @leave_ocb: leave the current OCB network * (invoked with the wireless_dev mutex held) * * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver * is responsible for continually initiating channel-switching operations * and returning to the base channel for communication with the AP. * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both * peers must be on the base channel when the call completes. * @start_nan: Start the NAN interface. * @stop_nan: Stop the NAN interface. * @add_nan_func: Add a NAN function. Returns negative value on failure. * On success @nan_func ownership is transferred to the driver and * it may access it outside of the scope of this function. The driver * should free the @nan_func when no longer needed by calling * cfg80211_free_nan_func(). * On success the driver should assign an instance_id in the * provided @nan_func. * @del_nan_func: Delete a NAN function. * @nan_change_conf: changes NAN configuration. The changed parameters must * be specified in @changes (using &enum cfg80211_nan_conf_changes); * All other parameters must be ignored. * * @set_multicast_to_unicast: configure multicast to unicast conversion for BSS * * @get_txq_stats: Get TXQ stats for interface or phy. If wdev is %NULL, this * function should return phy stats, and interface stats otherwise. * * @set_pmk: configure the PMK to be used for offloaded 802.1X 4-Way handshake. * If not deleted through @del_pmk the PMK remains valid until disconnect * upon which the driver should clear it. * (invoked with the wireless_dev mutex held) * @del_pmk: delete the previously configured PMK for the given authenticator. * (invoked with the wireless_dev mutex held) * * @external_auth: indicates result of offloaded authentication processing from * user space * * @tx_control_port: TX a control port frame (EAPoL). The noencrypt parameter * tells the driver that the frame should not be encrypted. * * @get_ftm_responder_stats: Retrieve FTM responder statistics, if available. * Statistics should be cumulative, currently no way to reset is provided. * @start_pmsr: start peer measurement (e.g. FTM) * @abort_pmsr: abort peer measurement * * @update_owe_info: Provide updated OWE info to driver. Driver implementing SME * but offloading OWE processing to the user space will get the updated * DH IE through this interface. * * @probe_mesh_link: Probe direct Mesh peer's link quality by sending data frame * and overrule HWMP path selection algorithm. * @set_tid_config: TID specific configuration, this can be peer or BSS specific * This callback may sleep. * @reset_tid_config: Reset TID specific configuration for the peer, for the * given TIDs.

This is a synchronous function. * @tg_send_cmd: Target mode data exchange using RF technology and framing * previously set with tg_configure_hw. The peer next command is returned * through callback cb. If an io error occurs or the peer didn't reply * within the specified timeout (ms), the error code is passed back through * the resp pointer. This is an asynchronous function. * @tg_listen: Put the device in listen mode waiting for data from the peer * device. This is an asynchronous function. * @tg_listen_mdaa: If supported, put the device in automatic listen mode with * mode detection and automatic anti-collision. In this mode, the device * automatically detects the RF technology and executes the anti-collision * detection using the command responses specified in mdaa_params. The * mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF * tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns * the NFC-DEP ATR_REQ command through cb.

It MUST be set * to 0x0 by the sender, in this first revision of NSH. Given the * widespread implementation of existing hardware that uses the first * nibble after an MPLS label stack for ECMP decision processing, this * document reserves version 01b and this value MUST NOT be used in * future versions of the protocol. Please see [RFC7325] for further * discussion of MPLS-related forwarding requirements. * * O bit: Setting this bit indicates an Operations, Administration, and * Maintenance (OAM) packet. The actual format and processing of SFC * OAM packets is outside the scope of this specification (see for * example [I-D.ietf-sfc-oam-framework] for one approach). * * The O bit MUST be set for OAM packets and MUST NOT be set for non-OAM * packets. The O bit MUST NOT be modified along the SFP. * * SF/SFF/SFC Proxy/Classifier implementations that do not support SFC * OAM procedures SHOULD discard packets with O bit set, but MAY support * a configurable parameter to enable forwarding received SFC OAM * packets unmodified to the next element in the chain. Forwarding OAM * packets unmodified by SFC elements that do not support SFC OAM * procedures may be acceptable for a subset of OAM functions, but can * result in unexpected outcomes for others, thus it is recommended to * analyze the impact of forwarding an OAM packet for all OAM functions * prior to enabling this behavior. The configurable parameter MUST be * disabled by default. * * TTL: Indicates the maximum SFF hops for an SFP. This field is used * for service plane loop detection. The initial TTL value SHOULD be * configurable via the control plane; the configured initial value can * be specific to one or more SFPs. If no initial value is explicitly * provided, the default initial TTL value of 63 MUST be used. Each SFF * involved in forwarding an NSH packet MUST decrement the TTL value by * 1 prior to NSH forwarding lookup. Decrementing by 1 from an incoming * value of 0 shall result in a TTL value of 63. The packet MUST NOT be * forwarded if TTL is, after decrement, 0. * * All other flag fields, marked U, are unassigned and available for * future use, see Section 11.2.1. Unassigned bits MUST be set to zero * upon origination, and MUST be ignored and preserved unmodified by * other NSH supporting elements. Elements which do not understand the * meaning of any of these bits MUST NOT modify their actions based on * those unknown bits. * * Length: The total length, in 4-byte words, of NSH including the Base * Header, the Service Path Header, the Fixed Length Context Header or * Variable Length Context Header(s). The length MUST be 0x6 for MD * Type equal to 0x1, and MUST be 0x2 or greater for MD Type equal to * 0x2. The length of the NSH header MUST be an integer multiple of 4 * bytes, thus variable length metadata is always padded out to a * multiple of 4 bytes. * * MD Type: Indicates the format of NSH beyond the mandatory Base Header * and the Service Path Header. MD Type defines the format of the * metadata being carried. * * 0x0 - This is a reserved value. Implementations SHOULD silently * discard packets with MD Type 0x0. * * 0x1 - This indicates that the format of the header includes a fixed * length Context Header (see Figure 4 below). * * 0x2 - This does not mandate any headers beyond the Base Header and * Service Path Header, but may contain optional variable length Context * Header(s). The semantics of the variable length Context Header(s) * are not defined in this document. The format of the optional * variable length Context Headers is provided in Section 2.5.1. * * 0xF - This value is reserved for experimentation and testing, as per * [RFC3692]. Implementations not explicitly configured to be part of * an experiment SHOULD silently discard packets with MD Type 0xF. * * Next Protocol: indicates the protocol type of the encapsulated data. * NSH does not alter the inner payload, and the semantics on the inner * protocol remain unchanged due to NSH service function chaining. * Please see the IANA Considerations section below, Section 11.2.5. * * This document defines the following Next Protocol values: * * 0x1: IPv4 * 0x2: IPv6 * 0x3: Ethernet * 0x4: NSH * 0x5: MPLS * 0xFE: Experiment 1 * 0xFF: Experiment 2 * * Packets with Next Protocol values not supported SHOULD be silently * dropped by default, although an implementation MAY provide a * configuration parameter to forward them. Additionally, an * implementation not explicitly configured for a specific experiment * [RFC3692] SHOULD silently drop packets with Next Protocol values 0xFE * and 0xFF. * * Service Path Identifier (SPI): Identifies a service path. * Participating nodes MUST use this identifier for Service Function * Path selection. The initial classifier MUST set the appropriate SPI * for a given classification result. * * Service Index (SI): Provides location within the SFP. The initial * classifier for a given SFP SHOULD set the SI to 255, however the * control plane MAY configure the initial value of SI as appropriate * (i.e., taking into account the length of the service function path). * The Service Index MUST be decremented by a value of 1 by Service * Functions or by SFC Proxy nodes after performing required services * and the new decremented SI value MUST be used in the egress packet's * NSH. The initial Classifier MUST send the packet to the first SFF in * the identified SFP for forwarding along an SFP. If re-classification * occurs, and that re-classification results in a new SPI, the * (re)classifier is, in effect, the initial classifier for the * resultant SPI. * * The SI is used in conjunction the with Service Path Identifier for * Service Function Path Selection and for determining the next SFF/SF * in the path. The SI is also valuable when troubleshooting or * reporting service paths. Additionally, while the TTL field is the * main mechanism for service plane loop detection, the SI can also be * used for detecting service plane loops. * * When the Base Header specifies MD Type = 0x1, a Fixed Length Context * Header (16-bytes) MUST be present immediately following the Service * Path Header. The value of a Fixed Length Context * Header that carries no metadata MUST be set to zero. * * When the base header specifies MD Type = 0x2, zero or more Variable * Length Context Headers MAY be added, immediately following the * Service Path Header (see Figure 5). Therefore, Length = 0x2, * indicates that only the Base Header followed by the Service Path * Header are present. The optional Variable Length Context Headers * MUST be of an integer number of 4-bytes. The base header Length * field MUST be used to determine the offset to locate the original * packet or frame for SFC nodes that require access to that * information. * * The format of the optional variable length Context Headers * * 0 1 2 3 * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | Metadata Class | Type |U| Length | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | Variable Metadata | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * * Metadata Class (MD Class): Defines the scope of the 'Type' field to * provide a hierarchical namespace. The IANA Considerations * Section 11.2.4 defines how the MD Class values can be allocated to * standards bodies, vendors, and others. * * Type: Indicates the explicit type of metadata being carried. The * definition of the Type is the responsibility of the MD Class owner. * * Unassigned bit: One unassigned bit is available for future use. This * bit MUST NOT be set, and MUST be ignored on receipt. * * Length: Indicates the length of the variable metadata, in bytes. In * case the metadata length is not an integer number of 4-byte words, * the sender MUST add pad bytes immediately following the last metadata * byte to extend the metadata to an integer number of 4-byte words. * The receiver MUST round up the length field to the nearest 4-byte * word boundary, to locate and process the next field in the packet. * The receiver MUST access only those bytes in the metadata indicated * by the length field (i.e., actual number of bytes) and MUST ignore * the remaining bytes up to the nearest 4-byte word boundary. The * Length may be 0 or greater. * * A value of 0 denotes a Context Header without a Variable Metadata * field. * * [0] https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/ */ /** * struct nsh_md1_ctx - Keeps track of NSH context data * @nshc<1-4>: NSH Contexts. */ struct nsh_md1_ctx { __be32 context[4]; }; struct nsh_md2_tlv { __be16 md_class; u8 type; u8 length; u8 md_value[]; }; struct nshhdr { __be16 ver_flags_ttl_len; u8 mdtype; u8 np; __be32 path_hdr; union { struct nsh_md1_ctx md1; struct nsh_md2_tlv md2; }; }; /* Masking NSH header fields. */ #define NSH_VER_MASK 0xc000 #define NSH_VER_SHIFT 14 #define NSH_FLAGS_MASK 0x3000 #define NSH_FLAGS_SHIFT 12 #define NSH_TTL_MASK 0x0fc0 #define NSH_TTL_SHIFT 6 #define NSH_LEN_MASK 0x003f #define NSH_LEN_SHIFT 0 #define NSH_MDTYPE_MASK 0x0f #define NSH_MDTYPE_SHIFT 0 #define NSH_SPI_MASK 0xffffff00 #define NSH_SPI_SHIFT 8 #define NSH_SI_MASK 0x000000ff #define NSH_SI_SHIFT 0 /* MD Type Registry. */ #define NSH_M_TYPE1 0x01 #define NSH_M_TYPE2 0x02 #define NSH_M_EXP1 0xFE #define NSH_M_EXP2 0xFF /* NSH Base Header Length */ #define NSH_BASE_HDR_LEN 8 /* NSH MD Type 1 header Length. */ #define NSH_M_TYPE1_LEN 24 /* NSH header maximum Length. */ #define NSH_HDR_MAX_LEN 256 /* NSH context headers maximum Length. */ #define NSH_CTX_HDRS_MAX_LEN 248 static inline struct nshhdr *nsh_hdr(struct sk_buff *skb) { return (struct nshhdr *)skb_network_header(skb); } static inline u16 nsh_hdr_len(const struct nshhdr *nsh) { return ((ntohs(nsh->ver_flags_ttl_len) & NSH_LEN_MASK) >> NSH_LEN_SHIFT) << 2; } static inline u8 nsh_get_ver(const struct nshhdr *nsh) { return (ntohs(nsh->ver_flags_ttl_len) & NSH_VER_MASK) >> NSH_VER_SHIFT; } static inline u8 nsh_get_flags(const struct nshhdr *nsh) { return (ntohs(nsh->ver_flags_ttl_len) & NSH_FLAGS_MASK) >> NSH_FLAGS_SHIFT; } static inline u8 nsh_get_ttl(const struct nshhdr *nsh) { return (ntohs(nsh->ver_flags_ttl_len) & NSH_TTL_MASK) >> NSH_TTL_SHIFT; } static inline void __nsh_set_xflag(struct nshhdr *nsh, u16 xflag, u16 xmask) { nsh->ver_flags_ttl_len = (nsh->ver_flags_ttl_len & ~htons(xmask)) | htons(xflag); } static inline void nsh_set_flags_and_ttl(struct nshhdr *nsh, u8 flags, u8 ttl) { __nsh_set_xflag(nsh, ((flags << NSH_FLAGS_SHIFT) & NSH_FLAGS_MASK) | ((ttl << NSH_TTL_SHIFT) & NSH_TTL_MASK), NSH_FLAGS_MASK | NSH_TTL_MASK); } static inline void nsh_set_flags_ttl_len(struct nshhdr *nsh, u8 flags, u8 ttl, u8 len) { len = len >> 2; __nsh_set_xflag(nsh, ((flags << NSH_FLAGS_SHIFT) & NSH_FLAGS_MASK) | ((ttl << NSH_TTL_SHIFT) & NSH_TTL_MASK) | ((len << NSH_LEN_SHIFT) & NSH_LEN_MASK), NSH_FLAGS_MASK | NSH_TTL_MASK | NSH_LEN_MASK); } int nsh_push(struct sk_buff *skb, const struct nshhdr *pushed_nh); int nsh_pop(struct sk_buff *skb); #endif /* __NET_NSH_H */ PK !

The driver has to * handle all the rest... * * The initial API also defines a specific handler in struct net_device * to handle wireless statistics. * * The initial APIs served us well and has proven a reasonably good design. * However, there is a few shortcommings : * o No events, everything is a request to the driver. * o Large ioctl function in driver with gigantic switch statement * (i.e. spaghetti code). * o Driver has to mess up with copy_to/from_user, and in many cases * does it unproperly. Common mistakes are : * * buffer overflows (no checks or off by one checks) * * call copy_to/from_user with irq disabled * o The user space interface is tied to ioctl because of the use * copy_to/from_user. * * New driver API (2002 -> onward) : * ------------------------------- * The new driver API is just a bunch of standard functions (handlers), * each handling a specific Wireless Extension. The driver just export * the list of handler it supports, and those will be called apropriately. * * I tried to keep the main advantage of the previous API (simplicity, * efficiency and light weight), and also I provide a good dose of backward * compatibility (most structures are the same, driver can use both API * simultaneously, ...). * Hopefully, I've also addressed the shortcomming of the initial API. * * The advantage of the new API are : * o Handling of Extensions in driver broken in small contained functions * o Tighter checks of ioctl before calling the driver * o Flexible commit strategy (at least, the start of it) * o Backward compatibility (can be mixed with old API) * o Driver doesn't have to worry about memory and user-space issues * The last point is important for the following reasons : * o You are now able to call the new driver API from any API you * want (including from within other parts of the kernel). * o Common mistakes are avoided (buffer overflow, user space copy * with irq disabled and so on). * * The Drawback of the new API are : * o bloat (especially kernel) * o need to migrate existing drivers to new API * My initial testing shows that the new API adds around 3kB to the kernel * and save between 0 and 5kB from a typical driver. * Also, as all structures and data types are unchanged, the migration is * quite straightforward (but tedious). * * --- * * The new driver API is defined below in this file. User space should * not be aware of what's happening down there... * * A new kernel wrapper is in charge of validating the IOCTLs and calling * the appropriate driver handler. This is implemented in : * # net/core/wireless.c * * The driver export the list of handlers in : * # include/linux/netdevice.h (one place) * * The new driver API is available for WIRELESS_EXT >= 13. * Good luck with migration to the new API ;-) */ /* ---------------------- THE IMPLEMENTATION ---------------------- */ /* * Some of the choice I've made are pretty controversials. Defining an * API is very much weighting compromises. This goes into some of the * details and the thinking behind the implementation. * * Implementation goals : * -------------------- * The implementation goals were as follow : * o Obvious : you should not need a PhD to understand what's happening, * the benefit is easier maintenance. * o Flexible : it should accommodate a wide variety of driver * implementations and be as flexible as the old API. * o Lean : it should be efficient memory wise to minimise the impact * on kernel footprint. * o Transparent to user space : the large number of user space * applications that use Wireless Extensions should not need * any modifications. * * Array of functions versus Struct of functions * --------------------------------------------- * 1) Having an array of functions allow the kernel code to access the * handler in a single lookup, which is much more efficient (think hash * table here). * 2) The only drawback is that driver writer may put their handler in * the wrong slot. This is trivial to test (I set the frequency, the * bitrate changes). Once the handler is in the proper slot, it will be * there forever, because the array is only extended at the end. * 3) Backward/forward compatibility : adding new handler just require * extending the array, so you can put newer driver in older kernel * without having to patch the kernel code (and vice versa). * * All handler are of the same generic type * ---------------------------------------- * That's a feature !!! * 1) Having a generic handler allow to have generic code, which is more * efficient. If each of the handler was individually typed I would need * to add a big switch in the kernel (== more bloat). This solution is * more scalable, adding new Wireless Extensions doesn't add new code. * 2) You can use the same handler in different slots of the array. For * hardware, it may be more efficient or logical to handle multiple * Wireless Extensions with a single function, and the API allow you to * do that. (An example would be a single record on the card to control * both bitrate and frequency, the handler would read the old record, * modify it according to info->cmd and rewrite it). * * Functions prototype uses union iwreq_data * ----------------------------------------- * Some would have preferred functions defined this way : * static int mydriver_ioctl_setrate(struct net_device *dev, * long rate, int auto) * 1) The kernel code doesn't "validate" the content of iwreq_data, and * can't do it (different hardware may have different notion of what a * valid frequency is), so we don't pretend that we do it. * 2) The above form is not extendable. If I want to add a flag (for * example to distinguish setting max rate and basic rate), I would * break the prototype. Using iwreq_data is more flexible. * 3) Also, the above form is not generic (see above). * 4) I don't expect driver developper using the wrong field of the * union (Doh !), so static typechecking doesn't add much value. * 5) Lastly, you can skip the union by doing : * static int mydriver_ioctl_setrate(struct net_device *dev, * struct iw_request_info *info, * struct iw_param *rrq, * char *extra) * And then adding the handler in the array like this : * (iw_handler) mydriver_ioctl_setrate, // SIOCSIWRATE * * Using functions and not a registry * ---------------------------------- * Another implementation option would have been for every instance to * define a registry (a struct containing all the Wireless Extensions) * and only have a function to commit the registry to the hardware. * 1) This approach can be emulated by the current code, but not * vice versa. * 2) Some drivers don't keep any configuration in the driver, for them * adding such a registry would be a significant bloat. * 3) The code to translate from Wireless Extension to native format is * needed anyway, so it would not reduce significantely the amount of code. * 4) The current approach only selectively translate Wireless Extensions * to native format and only selectively set, whereas the registry approach * would require to translate all WE and set all parameters for any single * change. * 5) For many Wireless Extensions, the GET operation return the current * dynamic value, not the value that was set. * * This header is <net/iw_handler.h> * --------------------------------- * 1) This header is kernel space only and should not be exported to * user space. Headers in "include/linux/" are exported, headers in * "include/net/" are not. * * Mixed 32/64 bit issues * ---------------------- * The Wireless Extensions are designed to be 64 bit clean, by using only * datatypes with explicit storage size. * There are some issues related to kernel and user space using different * memory model, and in particular 64bit kernel with 32bit user space. * The problem is related to struct iw_point, that contains a pointer * that *may* need to be translated. * This is quite messy. The new API doesn't solve this problem (it can't), * but is a step in the right direction : * 1) Meta data about each ioctl is easily available, so we know what type * of translation is needed. * 2) The move of data between kernel and user space is only done in a single * place in the kernel, so adding specific hooks in there is possible. * 3) In the long term, it allows to move away from using ioctl as the * user space API. * * So many comments and so few code * -------------------------------- * That's a feature. Comments won't bloat the resulting kernel binary. */ /***************************** INCLUDES *****************************/ #include <linux/wireless.h> /* IOCTL user space API */ #include <linux/if_ether.h> /***************************** VERSION *****************************/ /* * This constant is used to know which version of the driver API is * available.

(To be compatible with existing pfkeyv2 implementations, many rules with priority of 0x7fffffff are allowed to exist and such rules are ordered in an unpredictable way, thanks to bsd folks.) Lookup is plain linear search until the first match with selector. If "action" is "block", then we prohibit the flow, otherwise: if "xfrms_nr" is zero, the flow passes untransformed. Otherwise, policy entry has list of up to XFRM_MAX_DEPTH transformations, described by templates xfrm_tmpl. Each template is resolved to a complete xfrm_state (see below) and we pack bundle of transformations to a dst_entry returned to requestor. dst -. xfrm .-> xfrm_state #1 |---. child .-> dst -. xfrm .-> xfrm_state #2 |---. child .-> dst -. xfrm .-> xfrm_state #3 |---. child .-> NULL Bundles are cached at xrfm_policy struct (field ->bundles). Resolution of xrfm_tmpl ----------------------- Template contains: 1. ->mode Mode: transport or tunnel 2. ->id.proto Protocol: AH/ESP/IPCOMP 3. ->id.daddr Remote tunnel endpoint, ignored for transport mode. Q: allow to resolve security gateway? 4. ->id.spi If not zero, static SPI. 5. ->saddr Local tunnel endpoint, ignored for transport mode. 6. ->algos List of allowed algos. Plain bitmask now. Q: ealgos, aalgos, calgos. What a mess... 7. ->share Sharing mode. Q: how to implement private sharing mode? To add struct sock* to flow id? Having this template we search through SAD searching for entries with appropriate mode/proto/algo, permitted by selector. If no appropriate entry found, it is requested from key manager. PROBLEMS: Q: How to find all the bundles referring to a physical path for PMTU discovery? Seems, dst should contain list of all parents... and enter to infinite locking hierarchy disaster. No! It is easier, we will not search for them, let them find us. We add genid to each dst plus pointer to genid of raw IP route, pmtu disc will update pmtu on raw IP route and increase its genid. dst_check() will see this for top level and trigger resyncing metrics. Plus, it will be made via sk->sk_dst_cache.

May be overdone, * better to prove they can be removed * than the reverse. * Alan Cox : Added a zapped field for tcp to note * a socket is reset and must stay shut up * Alan Cox : New fields for options * Pauline Middelink : identd support * Alan Cox : Eliminate low level recv/recvfrom * David S. Miller : New socket lookup architecture. * Steve Whitehouse: Default routines for sock_ops * Arnaldo C. Melo : removed net_pinfo, tp_pinfo and made * protinfo be just a void pointer, as the * protocol specific parts were moved to * respective headers and ipv4/v6, etc now * use private slabcaches for its socks * Pedro Hortas : New flags field for socket options */ #ifndef _SOCK_H #define _SOCK_H #include <linux/hardirq.h> #include <linux/kernel.h> #include <linux/list.h> #include <linux/list_nulls.h> #include <linux/timer.h> #include <linux/cache.h> #include <linux/bitops.h> #include <linux/lockdep.h> #include <linux/netdevice.h> #include <linux/skbuff.h> /* struct sk_buff */ #include <linux/mm.h> #include <linux/security.h> #include <linux/slab.h> #include <linux/uaccess.h> #include <linux/page_counter.h> #include <linux/memcontrol.h> #include <linux/static_key.h> #include <linux/sched.h> #include <linux/wait.h> #include <linux/cgroup-defs.h> #include <linux/rbtree.h> #include <linux/filter.h> #include <linux/rculist_nulls.h> #include <linux/poll.h> #include <linux/sockptr.h> #include <linux/indirect_call_wrapper.h> #include <linux/atomic.h> #include <linux/refcount.h> #include <net/dst.h> #include <net/checksum.h> #include <net/tcp_states.h> #include <linux/net_tstamp.h> #include <net/l3mdev.h> #include <uapi/linux/socket.h> /* * This structure really needs to be cleaned up. * Most of it is for TCP, and not used by any of * the other protocols. */ /* Define this to get the SOCK_DBG debugging facility. */ #define SOCK_DEBUGGING #ifdef SOCK_DEBUGGING #define SOCK_DEBUG(sk, msg...) do { if ((sk) && sock_flag((sk), SOCK_DBG)) \ printk(KERN_DEBUG msg); } while (0) #else /* Validate arguments and do nothing */ static inline __printf(2, 3) void SOCK_DEBUG(const struct sock *sk, const char *msg, ...) { } #endif /* This is the per-socket lock.

This file codes a "divisionless" version of RED algorithm as written down in Fig.17 of the paper. Short description. ------------------ When a new packet arrives we calculate the average queue length: avg = (1-W)*avg + W*current_queue_len, W is the filter time constant (chosen as 2^(-Wlog)), it controls the inertia of the algorithm. To allow larger bursts, W should be decreased. if (avg > th_max) -> packet marked (dropped). if (avg < th_min) -> packet passes. if (th_min < avg < th_max) we calculate probability: Pb = max_P * (avg - th_min)/(th_max-th_min) and mark (drop) packet with this probability. Pb changes from 0 (at avg==th_min) to max_P (avg==th_max). max_P should be small (not 1), usually 0.01..0.02 is good value. max_P is chosen as a number, so that max_P/(th_max-th_min) is a negative power of two in order arithmetics to contain only shifts. Parameters, settable by user: ----------------------------- qth_min - bytes (should be < qth_max/2) qth_max - bytes (should be at least 2*qth_min and less limit) Wlog - bits (<32) log(1/W). Plog - bits (<32) Plog is related to max_P by formula: max_P = (qth_max-qth_min)/2^Plog; F.e. if qth_max=128K and qth_min=32K, then Plog=22 corresponds to max_P=0.02 Scell_log Stab Lookup table for log((1-W)^(t/t_ave).

To dequeue a frame from a * txq, it calls ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a * queue, it calls the .wake_tx_queue driver op. * * Drivers can optionally delegate responsibility for scheduling queues to * mac80211, to take advantage of airtime fairness accounting. In this case, to * obtain the next queue to pull frames from, the driver calls * ieee80211_next_txq(). The driver is then expected to return the txq using * ieee80211_return_txq(). * * For AP powersave TIM handling, the driver only needs to indicate if it has * buffered packets in the driver specific data structures by calling * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq * struct, mac80211 sets the appropriate TIM PVB bits and calls * .release_buffered_frames(). * In that callback the driver is therefore expected to release its own * buffered frames and afterwards also frames from the ieee80211_txq (obtained * via the usual ieee80211_tx_dequeue). */ struct device; /** * enum ieee80211_max_queues - maximum number of queues * * @IEEE80211_MAX_QUEUES: Maximum number of regular device queues. * @IEEE80211_MAX_QUEUE_MAP: bitmap with maximum queues set */ enum ieee80211_max_queues { IEEE80211_MAX_QUEUES = 16, IEEE80211_MAX_QUEUE_MAP = BIT(IEEE80211_MAX_QUEUES) - 1, }; #define IEEE80211_INVAL_HW_QUEUE 0xff /** * enum ieee80211_ac_numbers - AC numbers as used in mac80211 * @IEEE80211_AC_VO: voice * @IEEE80211_AC_VI: video * @IEEE80211_AC_BE: best effort * @IEEE80211_AC_BK: background */ enum ieee80211_ac_numbers { IEEE80211_AC_VO = 0, IEEE80211_AC_VI = 1, IEEE80211_AC_BE = 2, IEEE80211_AC_BK = 3, }; /** * struct ieee80211_tx_queue_params - transmit queue configuration * * The information provided in this structure is required for QoS * transmit queue configuration.

For such * drivers, mac80211 packet loss mechanism will not be triggered and driver * is completely depending on firmware event for station kickout. * * @IEEE80211_HW_SUPPORTS_TX_FRAG: Hardware does fragmentation by itself. * The stack will not do fragmentation. * The callback for @set_frag_threshold should be set as well. * * @IEEE80211_HW_SUPPORTS_TDLS_BUFFER_STA: Hardware supports buffer STA on * TDLS links. * * @IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP: The driver requires the * mgd_prepare_tx() callback to be called before transmission of a * deauthentication frame in case the association was completed but no * beacon was heard. This is required in multi-channel scenarios, where the * virtual interface might not be given air time for the transmission of * the frame, as it is not synced with the AP/P2P GO yet, and thus the * deauthentication frame might not be transmitted. * * @IEEE80211_HW_DOESNT_SUPPORT_QOS_NDP: The driver (or firmware) doesn't * support QoS NDP for AP probing - that's most likely a driver bug. * * @IEEE80211_HW_BUFF_MMPDU_TXQ: use the TXQ for bufferable MMPDUs, this of * course requires the driver to use TXQs to start with. * * @IEEE80211_HW_SUPPORTS_VHT_EXT_NSS_BW: (Hardware) rate control supports VHT * extended NSS BW (dot11VHTExtendedNSSBWCapable).

In that case, it will be told about the desired powersave mode * with the %IEEE80211_CONF_PS flag depending on the association status. * The hardware must take care of sending nullfunc frames when necessary, * i.e. when entering and leaving powersave mode. The hardware is required * to look at the AID in beacons and signal to the AP that it woke up when * it finds traffic directed to it. * * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused * with hardware wakeup and sleep states. Driver is responsible for waking * up the hardware before issuing commands to the hardware and putting it * back to sleep at appropriate times. * * When PS is enabled, hardware needs to wakeup for beacons and receive the * buffered multicast/broadcast frames after the beacon. Also it must be * possible to send frames and receive the acknowledment frame. * * Other hardware designs cannot send nullfunc frames by themselves and also * need software support for parsing the TIM bitmap. This is also supported * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still * required to pass up beacons. The hardware is still required to handle * waking up for multicast traffic; if it cannot the driver must handle that * as best as it can, mac80211 is too slow to do that. * * Dynamic powersave is an extension to normal powersave in which the * hardware stays awake for a user-specified period of time after sending a * frame so that reply frames need not be buffered and therefore delayed to * the next wakeup. It's compromise of getting good enough latency when * there's data traffic and still saving significantly power in idle * periods. * * Dynamic powersave is simply supported by mac80211 enabling and disabling * PS based on traffic. Driver needs to only set %IEEE80211_HW_SUPPORTS_PS * flag and mac80211 will handle everything automatically. Additionally, * hardware having support for the dynamic PS feature may set the * %IEEE80211_HW_SUPPORTS_DYNAMIC_PS flag to indicate that it can support * dynamic PS mode itself. The driver needs to look at the * @dynamic_ps_timeout hardware configuration value and use it that value * whenever %IEEE80211_CONF_PS is set.

It usually works so that * the firmware creates a checksum of the beacon but omits all constantly * changing elements (TSF, TIM etc). Whenever the checksum changes the * beacon is forwarded to the host, otherwise it will be just dropped. That * way the host will only receive beacons where some relevant information * (for example ERP protection or WMM settings) have changed. * * Beacon filter support is advertised with the %IEEE80211_VIF_BEACON_FILTER * interface capability. The driver needs to enable beacon filter support * whenever power save is enabled, that is %IEEE80211_CONF_PS is set. When * power save is enabled, the stack will not check for beacon loss and the * driver needs to notify about loss of beacons with ieee80211_beacon_loss(). * * The time (or number of beacons missed) until the firmware notifies the * driver of a beacon loss event (which in turn causes the driver to call * ieee80211_beacon_loss()) should be configurable and will be controlled * by mac80211 and the roaming algorithm in the future. * * Since there may be constantly changing information elements that nothing * in the software stack cares about, we will, in the future, have mac80211 * tell the driver which information elements are interesting in the sense * that we want to see changes in them. This will include * * - a list of information element IDs * - a list of OUIs for the vendor information element * * Ideally, the hardware would filter out any beacons without changes in the * requested elements, but if it cannot support that it may, at the expense * of some efficiency, filter out only a subset. For example, if the device * doesn't support checking for OUIs it should pass up all changes in all * vendor information elements. * * Note that change, for the sake of simplification, also includes information * elements appearing or disappearing from the beacon. * * Some hardware supports an "ignore list" instead, just make sure nothing * that was requested is on the ignore list, and include commonly changing * information element IDs in the ignore list, for example 11 (BSS load) and * the various vendor-assigned IEs with unknown contents (128, 129, 133-136, * 149, 150, 155, 156, 173, 176, 178, 179, 219); for forward compatibility * it could also include some currently unused IDs. * * * In addition to these capabilities, hardware should support notifying the * host of changes in the beacon RSSI. This is relevant to implement roaming * when no traffic is flowing (when traffic is flowing we see the RSSI of * the received data packets). This can consist in notifying the host when * the RSSI changes significantly or when it drops below or rises above * configurable thresholds. In the future these thresholds will also be * configured by mac80211 (which gets them from userspace) to implement * them as the roaming algorithm requires. * * If the hardware cannot implement this, the driver should ask it to * periodically pass beacon frames to the host so that software can do the * signal strength threshold checking. */ /** * DOC: Spatial multiplexing power save * * SMPS (Spatial multiplexing power save) is a mechanism to conserve * power in an 802.11n implementation.

However, for best CPU usage and power consumption, * having as few frames as possible percolate through the stack is * desirable. Hence, the hardware should filter as much as possible. * * To achieve this, mac80211 uses filter flags (see below) to tell * the driver's configure_filter() function which frames should be * passed to mac80211 and which should be filtered out. * * Before configure_filter() is invoked, the prepare_multicast() * callback is invoked with the parameters @mc_count and @mc_list * for the combined multicast address list of all virtual interfaces. * It's use is optional, and it returns a u64 that is passed to * configure_filter(). Additionally, configure_filter() has the * arguments @changed_flags telling which flags were changed and * @total_flags with the new flag states. * * If your device has no multicast address filters your driver will * need to check both the %FIF_ALLMULTI flag and the @mc_count * parameter to see whether multicast frames should be accepted * or dropped. * * All unsupported flags in @total_flags must be cleared. * Hardware does not support a flag if it is incapable of _passing_ * the frame to the stack. Otherwise the driver must ignore * the flag, but not clear it. * You must _only_ clear the flag (announce no support for the * flag to mac80211) if you are not able to pass the packet type * to the stack (so the hardware always filters it). * So for example, you should clear @FIF_CONTROL, if your hardware * always filters control frames. If your hardware always passes * control frames to the kernel and is incapable of filtering them, * you do _not_ clear the @FIF_CONTROL flag. * This rule applies to all other FIF flags as well. */ /** * DOC: AP support for powersaving clients * * In order to implement AP and P2P GO modes, mac80211 has support for * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD. * There currently is no support for sAPSD. * * There is one assumption that mac80211 makes, namely that a client * will not poll with PS-Poll and trigger with uAPSD at the same time. * Both are supported, and both can be used by the same client, but * they can't be used concurrently by the same client. This simplifies * the driver code. * * The first thing to keep in mind is that there is a flag for complete * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set, * mac80211 expects the driver to handle most of the state machine for * powersaving clients and will ignore the PM bit in incoming frames. * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of * stations' powersave transitions. In this mode, mac80211 also doesn't * handle PS-Poll/uAPSD. * * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the * PM bit in incoming frames for client powersave transitions. When a * station goes to sleep, we will stop transmitting to it. There is, * however, a race condition: a station might go to sleep while there is * data buffered on hardware queues. If the device has support for this * it will reject frames, and the driver should give the frames back to * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will * cause mac80211 to retry the frame when the station wakes up. The * driver is also notified of powersave transitions by calling its * @sta_notify callback. * * When the station is asleep, it has three choices: it can wake up, * it can PS-Poll, or it can possibly start a uAPSD service period. * Waking up is implemented by simply transmitting all buffered (and * filtered) frames to the station. This is the easiest case. When * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 * will inform the driver of this with the @allow_buffered_frames * callback; this callback is optional. mac80211 will then transmit * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER * on each frame. The last frame in the service period (or the only * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to * indicate that it ends the service period; as this frame must have * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS. * When TX status is reported for this frame, the service period is * marked has having ended and a new one can be started by the peer. * * Additionally, non-bufferable MMPDUs can also be transmitted by * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them. * * Another race condition can happen on some devices like iwlwifi * when there are frames queued for the station and it wakes up * or polls; the frames that are already queued could end up being * transmitted first instead, causing reordering and/or wrong * processing of the EOSP. The cause is that allowing frames to be * transmitted to a certain station is out-of-band communication to * the device. To allow this problem to be solved, the driver can * call ieee80211_sta_block_awake() if frames are buffered when it * is notified that the station went to sleep. When all these frames * have been filtered (see above), it must call the function again * to indicate that the station is no longer blocked. * * If the driver buffers frames in the driver for aggregation in any * way, it must use the ieee80211_sta_set_buffered() call when it is * notified of the station going to sleep to inform mac80211 of any * TIDs that have frames buffered. Note that when a station wakes up * this information is reset (hence the requirement to call it when * informed of the station going to sleep). Then, when a service * period starts for any reason, @release_buffered_frames is called * with the number of frames to be released and which TIDs they are * to come from. In this case, the driver is responsible for setting * the EOSP (for uAPSD) and MORE_DATA bits in the released frames, * to help the @more_data parameter is passed to tell the driver if * there is more data on other TIDs -- the TIDs to release frames * from are ignored since mac80211 doesn't know how many frames the * buffers for those TIDs contain. * * If the driver also implement GO mode, where absence periods may * shorten service periods (or abort PS-Poll responses), it must * filter those response frames except in the case of frames that * are buffered in the driver -- those must remain buffered to avoid * reordering. Because it is possible that no frames are released * in this case, the driver must call ieee80211_sta_eosp() * to indicate to mac80211 that the service period ended anyway. * * Finally, if frames from multiple TIDs are released from mac80211 * but the driver might reorder them, it must clear & set the flags * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP) * and also take care of the EOSP and MORE_DATA bits in the frame. * The driver may also use ieee80211_sta_eosp() in this case. * * Note that if the driver ever buffers frames other than QoS-data * frames, it must take care to never send a non-QoS-data frame as * the last frame in a service period, adding a QoS-nulldata frame * after a non-QoS-data frame if needed. */ /** * DOC: HW queue control * * Before HW queue control was introduced, mac80211 only had a single static * assignment of per-interface AC software queues to hardware queues. This * was problematic for a few reasons: * 1) off-channel transmissions might get stuck behind other frames * 2) multiple virtual interfaces couldn't be handled correctly * 3) after-DTIM frames could get stuck behind other frames * * To solve this, hardware typically uses multiple different queues for all * the different usages, and this needs to be propagated into mac80211 so it * won't have the same problem with the software queues. * * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability * flag that tells it that the driver implements its own queue control. To do * so, the driver will set up the various queues in each &struct ieee80211_vif * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and * if necessary will queue the frame on the right software queue that mirrors * the hardware queue. * Additionally, the driver has to then use these HW queue IDs for the queue * management functions (ieee80211_stop_queue() et al.) * * The driver is free to set up the queue mappings as needed, multiple virtual * interfaces may map to the same hardware queues if needed. The setup has to * happen during add_interface or change_interface callbacks.

This handler should, * preferably, never fail and stop queues appropriately. * Must be atomic. * * @start: Called before the first netdevice attached to the hardware * is enabled. This should turn on the hardware and must turn on * frame reception (for possibly enabled monitor interfaces.) * Returns negative error codes, these may be seen in userspace, * or zero. * When the device is started it should not have a MAC address * to avoid acknowledging frames before a non-monitor device * is added. * Must be implemented and can sleep. * * @stop: Called after last netdevice attached to the hardware * is disabled. This should turn off the hardware (at least * it must turn off frame reception.) * May be called right after add_interface if that rejects * an interface. If you added any work onto the mac80211 workqueue * you should ensure to cancel it on this callback. * Must be implemented and can sleep. * * @suspend: Suspend the device; mac80211 itself will quiesce before and * stop transmitting and doing any other configuration, and then * ask the device to suspend. This is only invoked when WoWLAN is * configured, otherwise the device is deconfigured completely and * reconfigured at resume time. * The driver may also impose special conditions under which it * wants to use the "normal" suspend (deconfigure), say if it only * supports WoWLAN when the device is associated. In this case, it * must return 1 from this function. * * @resume: If WoWLAN was configured, this indicates that mac80211 is * now resuming its operation, after this the device must be fully * functional again. If this returns an error, the only way out is * to also unregister the device. If it returns 1, then mac80211 * will also go through the regular complete restart on resume. * * @set_wakeup: Enable or disable wakeup when WoWLAN configuration is * modified. The reason is that device_set_wakeup_enable() is * supposed to be called when the configuration changes, not only * in suspend(). * * @add_interface: Called when a netdevice attached to the hardware is * enabled. Because it is not called for monitor mode devices, @start * and @stop must be implemented. * The driver should perform any initialization it needs before * the device can be enabled. The initial configuration for the * interface is given in the conf parameter. * The callback may refuse to add an interface by returning a * negative error code (which will be seen in userspace.) * Must be implemented and can sleep. * * @change_interface: Called when a netdevice changes type. This callback * is optional, but only if it is supported can interface types be * switched while the interface is UP. The callback may sleep. * Note that while an interface is being switched, it will not be * found by the interface iteration callbacks. * * @remove_interface: Notifies a driver that an interface is going down. * The @stop callback is called after this if it is the last interface * and no monitor interfaces are present. * When all interfaces are removed, the MAC address in the hardware * must be cleared so the device no longer acknowledges packets, * the mac_addr member of the conf structure is, however, set to the * MAC address of the device going away. * Hence, this callback must be implemented. It can sleep. * * @config: Handler for configuration requests. IEEE 802.11 code calls this * function to change hardware configuration, e.g., channel. * This function should never fail but returns a negative error code * if it does. The callback can sleep. * * @bss_info_changed: Handler for configuration requests related to BSS * parameters that may vary during BSS's lifespan, and may affect low * level driver (e.g. assoc/disassoc status, erp parameters). * This function should not be used if no BSS has been set, unless * for association indication. The @changed parameter indicates which * of the bss parameters has changed when a call is made. The callback * can sleep. * * @prepare_multicast: Prepare for multicast filter configuration. * This callback is optional, and its return value is passed * to configure_filter(). This callback must be atomic. * * @configure_filter: Configure the device's RX filter. * See the section "Frame filtering" for more information. * This callback must be implemented and can sleep. * * @config_iface_filter: Configure the interface's RX filter. * This callback is optional and is used to configure which frames * should be passed to mac80211. The filter_flags is the combination * of FIF_* flags. The changed_flags is a bit mask that indicates * which flags are changed. * This callback can sleep. * * @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit * must be set or cleared for a given STA. Must be atomic. * * @set_key: See the section "Hardware crypto acceleration" * This callback is only called between add_interface and * remove_interface calls, i.e. while the given virtual interface * is enabled. * Returns a negative error code if the key can't be added. * The callback can sleep. * * @update_tkip_key: See the section "Hardware crypto acceleration" * This callback will be called in the context of Rx. Called for drivers * which set IEEE80211_KEY_FLAG_TKIP_REQ_RX_P1_KEY. * The callback must be atomic. * * @set_rekey_data: If the device supports GTK rekeying, for example while the * host is suspended, it can assign this callback to retrieve the data * necessary to do GTK rekeying, this is the KEK, KCK and replay counter. * After rekeying was done it should (for example during resume) notify * userspace of the new replay counter using ieee80211_gtk_rekey_notify(). * * @set_default_unicast_key: Set the default (unicast) key index, useful for * WEP when the device sends data packets autonomously, e.g. for ARP * offloading. The index can be 0-3, or -1 for unsetting it. * * @hw_scan: Ask the hardware to service the scan request, no need to start * the scan state machine in stack. The scan must honour the channel * configuration done by the regulatory agent in the wiphy's * registered bands. The hardware (or the driver) needs to make sure * that power save is disabled. * The @req ie/ie_len members are rewritten by mac80211 to contain the * entire IEs after the SSID, so that drivers need not look at these * at all but just send them after the SSID -- mac80211 includes the * (extended) supported rates and HT information (where applicable). * When the scan finishes, ieee80211_scan_completed() must be called; * note that it also must be called when the scan cannot finish due to * any error unless this callback returned a negative error code. * This callback is also allowed to return the special return value 1, * this indicates that hardware scan isn't desirable right now and a * software scan should be done instead. A driver wishing to use this * capability must ensure its (hardware) scan capabilities aren't * advertised as more capable than mac80211's software scan is. * The callback can sleep. * * @cancel_hw_scan: Ask the low-level tp cancel the active hw scan. * The driver should ask the hardware to cancel the scan (if possible), * but the scan will be completed only after the driver will call * ieee80211_scan_completed(). * This callback is needed for wowlan, to prevent enqueueing a new * scan_work after the low-level driver was already suspended. * The callback can sleep. * * @sched_scan_start: Ask the hardware to start scanning repeatedly at * specific intervals. The driver must call the * ieee80211_sched_scan_results() function whenever it finds results. * This process will continue until sched_scan_stop is called. * * @sched_scan_stop: Tell the hardware to stop an ongoing scheduled scan. * In this case, ieee80211_sched_scan_stopped() must not be called. * * @sw_scan_start: Notifier function that is called just before a software scan * is started. Can be NULL, if the driver doesn't need this notification. * The mac_addr parameter allows supporting NL80211_SCAN_FLAG_RANDOM_ADDR, * the driver may set the NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR flag if it * can use this parameter. The callback can sleep. * * @sw_scan_complete: Notifier function that is called just after a * software scan finished. Can be NULL, if the driver doesn't need * this notification. * The callback can sleep. * * @get_stats: Return low-level statistics. * Returns zero if statistics are available. * The callback can sleep. * * @get_key_seq: If your device implements encryption in hardware and does * IV/PN assignment then this callback should be provided to read the * IV/PN for the given key from hardware. * The callback must be atomic. * * @set_frag_threshold: Configuration of fragmentation threshold. Assign this * if the device does fragmentation by itself. Note that to prevent the * stack from doing fragmentation IEEE80211_HW_SUPPORTS_TX_FRAG * should be set as well. * The callback can sleep. * * @set_rts_threshold: Configuration of RTS threshold (if device needs it) * The callback can sleep. * * @sta_add: Notifies low level driver about addition of an associated station, * AP, IBSS/WDS/mesh peer etc. This callback can sleep. * * @sta_remove: Notifies low level driver about removal of an associated * station, AP, IBSS/WDS/mesh peer etc. Note that after the callback * returns it isn't safe to use the pointer, not even RCU protected; * no RCU grace period is guaranteed between returning here and freeing * the station. See @sta_pre_rcu_remove if needed. * This callback can sleep. * * @sta_add_debugfs: Drivers can use this callback to add debugfs files * when a station is added to mac80211's station list. This callback * should be within a CONFIG_MAC80211_DEBUGFS conditional. This * callback can sleep. * * @sta_notify: Notifies low level driver about power state transition of an * associated station, AP, IBSS/WDS/mesh peer etc. For a VIF operating * in AP mode, this callback will not be called when the flag * %IEEE80211_HW_AP_LINK_PS is set. Must be atomic. * * @sta_set_txpwr: Configure the station tx power. This callback set the tx * power for the station. * This callback can sleep. * * @sta_state: Notifies low level driver about state transition of a * station (which can be the AP, a client, IBSS/WDS/mesh peer etc.) * This callback is mutually exclusive with @sta_add/@sta_remove. * It must not fail for down transitions but may fail for transitions * up the list of states. Also note that after the callback returns it * isn't safe to use the pointer, not even RCU protected - no RCU grace * period is guaranteed between returning here and freeing the station. * See @sta_pre_rcu_remove if needed. * The callback can sleep. * * @sta_pre_rcu_remove: Notify driver about station removal before RCU * synchronisation. This is useful if a driver needs to have station * pointers protected using RCU, it can then use this call to clear * the pointers instead of waiting for an RCU grace period to elapse * in @sta_state. * The callback can sleep. * * @sta_rc_update: Notifies the driver of changes to the bitrates that can be * used to transmit to the station. The changes are advertised with bits * from &enum ieee80211_rate_control_changed and the values are reflected * in the station data. This callback should only be used when the driver * uses hardware rate control (%IEEE80211_HW_HAS_RATE_CONTROL) since * otherwise the rate control algorithm is notified directly. * Must be atomic. * @sta_rate_tbl_update: Notifies the driver that the rate table changed. This * is only used if the configured rate control algorithm actually uses * the new rate table API, and is therefore optional. Must be atomic. * * @sta_statistics: Get statistics for this station. For example with beacon * filtering, the statistics kept by mac80211 might not be accurate, so * let the driver pre-fill the statistics. The driver can fill most of * the values (indicating which by setting the filled bitmap), but not * all of them make sense - see the source for which ones are possible. * Statistics that the driver doesn't fill will be filled by mac80211. * The callback can sleep. * * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max), * bursting) for a hardware TX queue. * Returns a negative error code on failure. * The callback can sleep. * * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently, * this is only used for IBSS mode BSSID merging and debugging. Is not a * required function. * The callback can sleep. * * @set_tsf: Set the TSF timer to the specified value in the firmware/hardware. * Currently, this is only used for IBSS mode debugging. Is not a * required function. * The callback can sleep. * * @offset_tsf: Offset the TSF timer by the specified value in the * firmware/hardware. Preferred to set_tsf as it avoids delay between * calling set_tsf() and hardware getting programmed, which will show up * as TSF delay. Is not a required function. * The callback can sleep. * * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize * with other STAs in the IBSS. This is only used in IBSS mode. This * function is optional if the firmware/hardware takes full care of * TSF synchronization. * The callback can sleep. * * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us. * This is needed only for IBSS mode and the result of this function is * used to determine whether to reply to Probe Requests. * Returns non-zero if this device sent the last beacon. * The callback can sleep. * * @get_survey: Return per-channel survey information * * @rfkill_poll: Poll rfkill hardware state. If you need this, you also * need to set wiphy->rfkill_poll to %true before registration, * and need to call wiphy_rfkill_set_hw_state() in the callback. * The callback can sleep. * * @set_coverage_class: Set slot time for given coverage class as specified * in IEEE 802.11-2007 section 17.3.8.6 and modify ACK timeout * accordingly; coverage class equals to -1 to enable ACK timeout * estimation algorithm (dynack). To disable dynack set valid value for * coverage class. This callback is not required and may sleep. * * @testmode_cmd: Implement a cfg80211 test mode command. The passed @vif may * be %NULL. The callback can sleep. * @testmode_dump: Implement a cfg80211 test mode dump. The callback can sleep. * * @flush: Flush all pending frames from the hardware queue, making sure * that the hardware queues are empty. The @queues parameter is a bitmap * of queues to flush, which is useful if different virtual interfaces * use different hardware queues; it may also indicate all queues. * If the parameter @drop is set to %true, pending frames may be dropped. * Note that vif can be NULL. * The callback can sleep. * * @channel_switch: Drivers that need (or want) to offload the channel * switch operation for CSAs received from the AP may implement this * callback. They must then call ieee80211_chswitch_done() to indicate * completion of the channel switch. * * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may * reject TX/RX mask combinations they cannot support by returning -EINVAL * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). * * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). * * @remain_on_channel: Starts an off-channel period on the given channel, must * call back to ieee80211_ready_on_channel() when on that channel. Note * that normal channel traffic is not stopped as this is intended for hw * offload. Frames to transmit on the off-channel channel are transmitted * normally except for the %IEEE80211_TX_CTL_TX_OFFCHAN flag. When the * duration (which will always be non-zero) expires, the driver must call * ieee80211_remain_on_channel_expired(). * Note that this callback may be called while the device is in IDLE and * must be accepted in this case. * This callback may sleep. * @cancel_remain_on_channel: Requests that an ongoing off-channel period is * aborted before it expires. This callback may sleep. * * @set_ringparam: Set tx and rx ring sizes. * * @get_ringparam: Get tx and rx ring current and maximum sizes. * * @tx_frames_pending: Check if there is any pending frame in the hardware * queues before entering power save. * * @set_bitrate_mask: Set a mask of rates to be used for rate control selection * when transmitting a frame. Currently only legacy rates are handled. * The callback can sleep. * @event_callback: Notify driver about any event in mac80211. See * &enum ieee80211_event_type for the different types. * The callback must be atomic. * * @release_buffered_frames: Release buffered frames according to the given * parameters. In the case where the driver buffers some frames for * sleeping stations mac80211 will use this callback to tell the driver * to release some frames, either for PS-poll or uAPSD. * Note that if the @more_data parameter is %false the driver must check * if there are more frames on the given TIDs, and if there are more than * the frames being released then it must still set the more-data bit in * the frame. If the @more_data parameter is %true, then of course the * more-data bit must always be set. * The @tids parameter tells the driver which TIDs to release frames * from, for PS-poll it will always have only a single bit set. * In the case this is used for a PS-poll initiated release, the * @num_frames parameter will always be 1 so code can be shared. In * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag * on the TX status (and must report TX status) so that the PS-poll * period is properly ended. This is used to avoid sending multiple * responses for a retried PS-poll frame. * In the case this is used for uAPSD, the @num_frames parameter may be * bigger than one, but the driver may send fewer frames (it must send * at least one, however). In this case it is also responsible for * setting the EOSP flag in the QoS header of the frames. Also, when the * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP * on the last frame in the SP. Alternatively, it may call the function * ieee80211_sta_eosp() to inform mac80211 of the end of the SP. * This callback must be atomic. * @allow_buffered_frames: Prepare device to allow the given number of frames * to go out to the given station. The frames will be sent by mac80211 * via the usual TX path after this call. The TX information for frames * released will also have the %IEEE80211_TX_CTL_NO_PS_BUFFER flag set * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case * frames from multiple TIDs are released and the driver might reorder * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag * on the last frame and clear it on all others and also handle the EOSP * bit in the QoS header correctly. Alternatively, it can also call the * ieee80211_sta_eosp() function. * The @tids parameter is a bitmap and tells the driver which TIDs the * frames will be on; it will at most have two bits set. * This callback must be atomic. * * @get_et_sset_count: Ethtool API to get string-set count. * * @get_et_stats: Ethtool API to get a set of u64 stats. * * @get_et_strings: Ethtool API to get a set of strings to describe stats * and perhaps other supported types of ethtool data-sets. * * @mgd_prepare_tx: Prepare for transmitting a management frame for association * before associated. In multi-channel scenarios, a virtual interface is * bound to a channel before it is associated, but as it isn't associated * yet it need not necessarily be given airtime, in particular since any * transmission to a P2P GO needs to be synchronized against the GO's * powersave state. mac80211 will call this function before transmitting a * management frame prior to having successfully associated to allow the * driver to give it channel time for the transmission, to get a response * and to be able to synchronize with the GO. * For drivers that set %IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP, mac80211 * would also call this function before transmitting a deauthentication * frame in case that no beacon was heard from the AP/P2P GO. * The callback will be called before each transmission and upon return * mac80211 will transmit the frame right away. * Additional information is passed in the &struct ieee80211_prep_tx_info * data. If duration there is greater than zero, mac80211 hints to the * driver the duration for which the operation is requested. * The callback is optional and can (should!) sleep. * @mgd_complete_tx: Notify the driver that the response frame for a previously * transmitted frame announced with @mgd_prepare_tx was received, the data * is filled similarly to @mgd_prepare_tx though the duration is not used. * Note that this isn't always called for each mgd_prepare_tx() call, for * example for SAE the 'confirm' messages can be on the air in any order. * * @mgd_protect_tdls_discover: Protect a TDLS discovery session. After sending * a TDLS discovery-request, we expect a reply to arrive on the AP's * channel. We must stay on the channel (no PSM, scan, etc.), since a TDLS * setup-response is a direct packet not buffered by the AP. * mac80211 will call this function just before the transmission of a TDLS * discovery-request. The recommended period of protection is at least * 2 * (DTIM period). * The callback is optional and can sleep. * * @add_chanctx: Notifies device driver about new channel context creation. * This callback may sleep. * @remove_chanctx: Notifies device driver about channel context destruction. * This callback may sleep. * @change_chanctx: Notifies device driver about channel context changes that * may happen when combining different virtual interfaces on the same * channel context with different settings * This callback may sleep. * @assign_vif_chanctx: Notifies device driver about channel context being bound * to vif. Possible use is for hw queue remapping. * This callback may sleep. * @unassign_vif_chanctx: Notifies device driver about channel context being * unbound from vif. * This callback may sleep. * @switch_vif_chanctx: switch a number of vifs from one chanctx to * another, as specified in the list of * @ieee80211_vif_chanctx_switch passed to the driver, according * to the mode defined in &ieee80211_chanctx_switch_mode. * This callback may sleep. * * @start_ap: Start operation on the AP interface, this is called after all the * information in bss_conf is set and beacon can be retrieved. A channel * context is bound before this is called. Note that if the driver uses * software scan or ROC, this (and @stop_ap) isn't called when the AP is * just "paused" for scanning/ROC, which is indicated by the beacon being * disabled/enabled via @bss_info_changed. * @stop_ap: Stop operation on the AP interface. * * @reconfig_complete: Called after a call to ieee80211_restart_hw() and * during resume, when the reconfiguration has completed. * This can help the driver implement the reconfiguration step (and * indicate mac80211 is ready to receive frames). * This callback may sleep. * * @ipv6_addr_change: IPv6 address assignment on the given interface changed. * Currently, this is only called for managed or P2P client interfaces. * This callback is optional; it must not sleep. * * @channel_switch_beacon: Starts a channel switch to a new channel. * Beacons are modified to include CSA or ECSA IEs before calling this * function. The corresponding count fields in these IEs must be * decremented, and when they reach 1 the driver must call * ieee80211_csa_finish(). Drivers which use ieee80211_beacon_get() * get the csa counter decremented by mac80211, but must check if it is * 1 using ieee80211_beacon_counter_is_complete() after the beacon has been * transmitted and then call ieee80211_csa_finish(). * If the CSA count starts as zero or 1, this function will not be called, * since there won't be any time to beacon before the switch anyway. * @pre_channel_switch: This is an optional callback that is called * before a channel switch procedure is started (ie. when a STA * gets a CSA or a userspace initiated channel-switch), allowing * the driver to prepare for the channel switch. * @post_channel_switch: This is an optional callback that is called * after a channel switch procedure is completed, allowing the * driver to go back to a normal configuration. * @abort_channel_switch: This is an optional callback that is called * when channel switch procedure was completed, allowing the * driver to go back to a normal configuration. * @channel_switch_rx_beacon: This is an optional callback that is called * when channel switch procedure is in progress and additional beacon with * CSA IE was received, allowing driver to track changes in count. * @join_ibss: Join an IBSS (on an IBSS interface); this is called after all * information in bss_conf is set up and the beacon can be retrieved. A * channel context is bound before this is called. * @leave_ibss: Leave the IBSS again. * * @get_expected_throughput: extract the expected throughput towards the * specified station. The returned value is expressed in Kbps. It returns 0 * if the RC algorithm does not have proper data to provide. * * @get_txpower: get current maximum tx power (in dBm) based on configuration * and hardware limits. * * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver * is responsible for continually initiating channel-switching operations * and returning to the base channel for communication with the AP. The * driver receives a channel-switch request template and the location of * the switch-timing IE within the template as part of the invocation. * The template is valid only within the call, and the driver can * optionally copy the skb for further re-use. * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both * peers must be on the base channel when the call completes. * @tdls_recv_channel_switch: a TDLS channel-switch related frame (request or * response) has been received from a remote peer. The driver gets * parameters parsed from the incoming frame and may use them to continue * an ongoing channel-switch operation. In addition, a channel-switch * response template is provided, together with the location of the * switch-timing IE within the template. The skb can only be used within * the function call. * * @wake_tx_queue: Called when new packets have been added to the queue. * @sync_rx_queues: Process all pending frames in RSS queues. This is a * synchronization which is needed in case driver has in its RSS queues * pending frames that were received prior to the control path action * currently taken (e.g. disassociation) but are not processed yet. * * @start_nan: join an existing NAN cluster, or create a new one. * @stop_nan: leave the NAN cluster. * @nan_change_conf: change NAN configuration. The data in cfg80211_nan_conf * contains full new configuration and changes specify which parameters * are changed with respect to the last NAN config. * The driver gets both full configuration and the changed parameters since * some devices may need the full configuration while others need only the * changed parameters. * @add_nan_func: Add a NAN function. Returns 0 on success. The data in * cfg80211_nan_func must not be referenced outside the scope of * this call. * @del_nan_func: Remove a NAN function. The driver must call * ieee80211_nan_func_terminated() with * NL80211_NAN_FUNC_TERM_REASON_USER_REQUEST reason code upon removal. * @can_aggregate_in_amsdu: Called in order to determine if HW supports * aggregating two specific frames in the same A-MSDU. The relation * between the skbs should be symmetric and transitive. Note that while * skb is always a real frame, head may or may not be an A-MSDU. * @get_ftm_responder_stats: Retrieve FTM responder statistics, if available. * Statistics should be cumulative, currently no way to reset is provided. * * @start_pmsr: start peer measurement (e.g. FTM) (this call can sleep) * @abort_pmsr: abort peer measurement (this call can sleep) * @set_tid_config: Apply TID specific configurations. This callback may sleep. * @reset_tid_config: Reset TID specific configuration for the peer. * This callback may sleep. * @update_vif_offload: Update virtual interface offload flags * This callback may sleep. * @sta_set_4addr: Called to notify the driver when a station starts/stops using * 4-address mode * @set_sar_specs: Update the SAR (TX power) settings. * @sta_set_decap_offload: Called to notify the driver when a station is allowed * to use rx decapsulation offload * @add_twt_setup: Update hw with TWT agreement parameters received from the peer. * This callback allows the hw to check if requested parameters * are supported and if there is enough room for a new agreement. * The hw is expected to set agreement result in the req_type field of * twt structure. * @twt_teardown_request: Update the hw with TWT teardown request received * from the peer. */ struct ieee80211_ops { void (*tx)(struct ieee80211_hw *hw, struct ieee80211_tx_control *control, struct sk_buff *skb);

The details are all in the datasheets but I will try to give a short description here. Inputs ====== There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have to select which tuner input to use and which SCART input to use. The selected tuner input, the selected SCART input and all I2S inputs go to the DSP (the tuner input first goes through the demodulator). The DSP handles things like volume, bass/treble, balance, and some chips have support for surround sound. It has several outputs: MAIN, AUX, I2S and SCART1/2. Each output can select which DSP input to use. So the MAIN output can select the tuner input while at the same time the SCART1 output uses the I2S input. Outputs ======= Most DSP outputs are also the outputs of the msp3400. However, the SCART outputs of the msp3400 can select which input to use: either the SCART1 or SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely bypassing the DSP. Summary ======= So to specify a complete routing scheme for the msp3400 you will have to specify in the 'input' arg of the s_routing function: 1) which tuner input to use 2) which SCART input to use 3) which DSP input to use for each DSP output And in the 'output' arg of the s_routing function you specify: 1) which SCART input to use for each SCART output Depending on how the msp is wired to the other components you can ignore or mute certain inputs or outputs. Also, depending on the msp version only a subset of the inputs or outputs may be present. At the end of this header some tables are added containing a list of what is available for each msp version. */ /* Inputs to the DSP unit: two independent selections have to be made: 1) the tuner (SIF) input 2) the SCART input Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner input, bits 4-7 are reserved. */ /* SCART input to DSP selection */ #define MSP_IN_SCART1 0 /* Pin SC1_IN */ #define MSP_IN_SCART2 1 /* Pin SC2_IN */ #define MSP_IN_SCART3 2 /* Pin SC3_IN */ #define MSP_IN_SCART4 3 /* Pin SC4_IN */ #define MSP_IN_MONO 6 /* Pin MONO_IN */ #define MSP_IN_MUTE 7 /* Mute DSP input */ #define MSP_SCART_TO_DSP(in) (in) /* Tuner input to demodulator and DSP selection */ #define MSP_IN_TUNER1 0 /* Analog Sound IF input pin ANA_IN1 */ #define MSP_IN_TUNER2 1 /* Analog Sound IF input pin ANA_IN2 */ #define MSP_TUNER_TO_DSP(in) ((in) << 3) /* The msp has up to 5 DSP outputs, each output can independently select a DSP input.

There also is a quasi-peak detector output, but that is not used by this driver and is set to the same input as the loudspeaker output. Not all outputs are supported by all msp models. Setting the input of an unsupported output will be ignored by the driver. There are up to 16 DSP inputs to choose from, so each output is assigned 4 bits. Note: the 44x8G can mix two inputs and feed the result back to the DSP. This is currently not implemented. Also not implemented is the multi-channel capable I2S3 input of the 44x0G.

Ditto for the corresponding * _unregister() routines. * * atomic_notifier_chain_unregister(), blocking_notifier_chain_unregister(), * and srcu_notifier_chain_unregister() _must not_ be called from within * the call chain. * * SRCU notifier chains are an alternative form of blocking notifier chains. * They use SRCU (Sleepable Read-Copy Update) instead of rw-semaphores for * protection of the chain links. This means there is _very_ low overhead * in srcu_notifier_call_chain(): no cache bounces and no memory barriers. * As compensation, srcu_notifier_chain_unregister() is rather expensive. * SRCU notifier chains should be used when the chain will be called very * often but notifier_blocks will seldom be removed. */ struct notifier_block; typedef int (*notifier_fn_t)(struct notifier_block *nb, unsigned long action, void *data); struct notifier_block { notifier_fn_t notifier_call; struct notifier_block __rcu *next; int priority; }; struct atomic_notifier_head { spinlock_t lock; struct notifier_block __rcu *head; }; struct blocking_notifier_head { struct rw_semaphore rwsem; struct notifier_block __rcu *head; }; struct raw_notifier_head { struct notifier_block __rcu *head; }; struct srcu_notifier_head { struct mutex mutex; struct srcu_struct srcu; struct notifier_block __rcu *head; }; #define ATOMIC_INIT_NOTIFIER_HEAD(name) do { \ spin_lock_init(&(name)->lock); \ (name)->head = NULL; \ } while (0) #define BLOCKING_INIT_NOTIFIER_HEAD(name) do { \ init_rwsem(&(name)->rwsem); \ (name)->head = NULL; \ } while (0) #define RAW_INIT_NOTIFIER_HEAD(name) do { \ (name)->head = NULL; \ } while (0) /* srcu_notifier_heads must be cleaned up dynamically */ extern void srcu_init_notifier_head(struct srcu_notifier_head *nh); #define srcu_cleanup_notifier_head(name) \ cleanup_srcu_struct(&(name)->srcu); #define ATOMIC_NOTIFIER_INIT(name) { \ .lock = __SPIN_LOCK_UNLOCKED(name.lock), \ .head = NULL } #define BLOCKING_NOTIFIER_INIT(name) { \ .rwsem = __RWSEM_INITIALIZER((name).rwsem), \ .head = NULL } #define RAW_NOTIFIER_INIT(name) { \ .head = NULL } #define SRCU_NOTIFIER_INIT(name, pcpu) \ { \ .mutex = __MUTEX_INITIALIZER(name.mutex), \ .head = NULL, \ .srcu = __SRCU_STRUCT_INIT(name.srcu, pcpu), \ } #define ATOMIC_NOTIFIER_HEAD(name) \ struct atomic_notifier_head name = \ ATOMIC_NOTIFIER_INIT(name) #define BLOCKING_NOTIFIER_HEAD(name) \ struct blocking_notifier_head name = \ BLOCKING_NOTIFIER_INIT(name) #define RAW_NOTIFIER_HEAD(name) \ struct raw_notifier_head name = \ RAW_NOTIFIER_INIT(name) #ifdef CONFIG_TREE_SRCU #define _SRCU_NOTIFIER_HEAD(name, mod) \ static DEFINE_PER_CPU(struct srcu_data, name##_head_srcu_data); \ mod struct srcu_notifier_head name = \ SRCU_NOTIFIER_INIT(name, name##_head_srcu_data) #else #define _SRCU_NOTIFIER_HEAD(name, mod) \ mod struct srcu_notifier_head name = \ SRCU_NOTIFIER_INIT(name, name) #endif #define SRCU_NOTIFIER_HEAD(name) \ _SRCU_NOTIFIER_HEAD(name, /* not static */) #define SRCU_NOTIFIER_HEAD_STATIC(name) \ _SRCU_NOTIFIER_HEAD(name, static) #ifdef __KERNEL__ extern int atomic_notifier_chain_register(struct atomic_notifier_head *nh, struct notifier_block *nb); extern int blocking_notifier_chain_register(struct blocking_notifier_head *nh, struct notifier_block *nb); extern int raw_notifier_chain_register(struct raw_notifier_head *nh, struct notifier_block *nb); extern int srcu_notifier_chain_register(struct srcu_notifier_head *nh, struct notifier_block *nb); extern int atomic_notifier_chain_unregister(struct atomic_notifier_head *nh, struct notifier_block *nb); extern int blocking_notifier_chain_unregister(struct blocking_notifier_head *nh, struct notifier_block *nb); extern int raw_notifier_chain_unregister(struct raw_notifier_head *nh, struct notifier_block *nb); extern int srcu_notifier_chain_unregister(struct srcu_notifier_head *nh, struct notifier_block *nb); extern int atomic_notifier_call_chain(struct atomic_notifier_head *nh, unsigned long val, void *v); extern int blocking_notifier_call_chain(struct blocking_notifier_head *nh, unsigned long val, void *v); extern int raw_notifier_call_chain(struct raw_notifier_head *nh, unsigned long val, void *v); extern int srcu_notifier_call_chain(struct srcu_notifier_head *nh, unsigned long val, void *v); extern int blocking_notifier_call_chain_robust(struct blocking_notifier_head *nh, unsigned long val_up, unsigned long val_down, void *v); extern int raw_notifier_call_chain_robust(struct raw_notifier_head *nh, unsigned long val_up, unsigned long val_down, void *v); #define NOTIFY_DONE 0x0000 /* Don't care */ #define NOTIFY_OK 0x0001 /* Suits me */ #define NOTIFY_STOP_MASK 0x8000 /* Don't call further */ #define NOTIFY_BAD (NOTIFY_STOP_MASK|0x0002) /* Bad/Veto action */ /* * Clean way to return from the notifier and stop further calls. */ #define NOTIFY_STOP (NOTIFY_OK|NOTIFY_STOP_MASK) /* Encapsulate (negative) errno value (in particular, NOTIFY_BAD <=> EPERM). */ static inline int notifier_from_errno(int err) { if (err) return NOTIFY_STOP_MASK | (NOTIFY_OK - err); return NOTIFY_OK; } /* Restore (negative) errno value from notify return value. */ static inline int notifier_to_errno(int ret) { ret &= ~NOTIFY_STOP_MASK; return ret > NOTIFY_OK ?

Always preceded by an @open call and one or more @read * calls. * * @psi: in: pointer to the struct pstore_info for the backend * * Returns 0 on success, and non-zero on error. (Though pstore will * ignore the error.) * * @read: * Read next available backend record. Called after a successful * @open. * * @record: * pointer to record to populate. @buf should be allocated * by the backend and filled. At least @type and @id should * be populated, since these are used when creating pstorefs * file names. * * Returns record size on success, zero when no more records are * available, or negative on error. * * @write: * A newly generated record needs to be written to backend storage. * * @record: * pointer to record metadata. When @type is PSTORE_TYPE_DMESG, * @buf will be pointing to the preallocated @psi.buf, since * memory allocation may be broken during an Oops. Regardless, * @buf must be proccesed or copied before returning. The * backend is also expected to write @id with something that * can help identify this record to a future @erase callback. * The @time field will be prepopulated with the current time, * when available. The @size field will have the size of data * in @buf. * * Returns 0 on success, and non-zero on error. * * @write_user: * Perform a frontend write to a backend record, using a specified * buffer that is coming directly from userspace, instead of the * @record @buf. * * @record: pointer to record metadata. * @buf: pointer to userspace contents to write to backend * * Returns 0 on success, and non-zero on error. * * @erase: * Delete a record from backend storage. Different backends * identify records differently, so entire original record is * passed back to assist in identification of what the backend * should remove from storage. * * @record: pointer to record metadata. * * Returns 0 on success, and non-zero on error. * */ struct pstore_info { struct module *owner; const char *name; spinlock_t buf_lock; char *buf; size_t bufsize; struct mutex read_mutex; int flags; int max_reason; void *data; int (*open)(struct pstore_info *psi); int (*close)(struct pstore_info *psi); ssize_t (*read)(struct pstore_record *record); int (*write)(struct pstore_record *record); int (*write_user)(struct pstore_record *record, const char __user *buf); int (*erase)(struct pstore_record *record); }; /* Supported frontends */ #define PSTORE_FLAGS_DMESG BIT(0) #define PSTORE_FLAGS_CONSOLE BIT(1) #define PSTORE_FLAGS_FTRACE BIT(2) #define PSTORE_FLAGS_PMSG BIT(3) extern int pstore_register(struct pstore_info *); extern void pstore_unregister(struct pstore_info *); struct pstore_ftrace_record { unsigned long ip; unsigned long parent_ip; u64 ts; }; /* * ftrace related stuff: Both backends and frontends need these so expose * them here. */ #if NR_CPUS <= 2 && defined(CONFIG_ARM_THUMB) #define PSTORE_CPU_IN_IP 0x1 #elif NR_CPUS <= 4 && defined(CONFIG_ARM) #define PSTORE_CPU_IN_IP 0x3 #endif #define TS_CPU_SHIFT 8 #define TS_CPU_MASK (BIT(TS_CPU_SHIFT) - 1) /* * If CPU number can be stored in IP, store it there, otherwise store it in * the time stamp.

TCPM signals TCPC to enable the mechanism upon * entering connected state and signals disabling upon disconnect. * @set_auto_vbus_discharge_threshold: * Mandatory when enable_auto_vbus_discharge is implemented.

Always provide this; some controllers * only use PIO, or don't use DMA for some endpoints. * @dma: DMA address corresponding to 'buf'. If you don't set this * field, and the usb controller needs one, it is responsible * for mapping and unmapping the buffer. * @sg: a scatterlist for SG-capable controllers. * @num_sgs: number of SG entries * @num_mapped_sgs: number of SG entries mapped to DMA (internal) * @length: Length of that data * @stream_id: The stream id, when USB3.0 bulk streams are being used * @is_last: Indicates if this is the last request of a stream_id before * switching to a different stream (required for DWC3 controllers). * @no_interrupt: If true, hints that no completion irq is needed. * Helpful sometimes with deep request queues that are handled * directly by DMA controllers. * @zero: If true, when writing data, makes the last packet be "short" * by adding a zero length packet as needed; * @short_not_ok: When reading data, makes short packets be * treated as errors (queue stops advancing till cleanup). * @dma_mapped: Indicates if request has been mapped to DMA (internal) * @complete: Function called when request completes, so this request and * its buffer may be re-used. The function will always be called with * interrupts disabled, and it must not sleep. * Reads terminate with a short packet, or when the buffer fills, * whichever comes first. When writes terminate, some data bytes * will usually still be in flight (often in a hardware fifo). * Errors (for reads or writes) stop the queue from advancing * until the completion function returns, so that any transfers * invalidated by the error may first be dequeued. * @context: For use by the completion callback * @list: For use by the gadget driver. * @frame_number: Reports the interval number in (micro)frame in which the * isochronous transfer was transmitted or received. * @status: Reports completion code, zero or a negative errno. * Normally, faults block the transfer queue from advancing until * the completion callback returns. * Code "-ESHUTDOWN" indicates completion caused by device disconnect, * or when the driver disabled the endpoint. * @actual: Reports bytes transferred to/from the buffer. For reads (OUT * transfers) this may be less than the requested length. If the * short_not_ok flag is set, short reads are treated as errors * even when status otherwise indicates successful completion. * Note that for writes (IN transfers) some data bytes may still * reside in a device-side FIFO when the request is reported as * complete. * * These are allocated/freed through the endpoint they're used with. The * hardware's driver can add extra per-request data to the memory it returns, * which often avoids separate memory allocations (potential failures), * later when the request is queued. * * Request flags affect request handling, such as whether a zero length * packet is written (the "zero" flag), whether a short read should be * treated as an error (blocking request queue advance, the "short_not_ok" * flag), or hinting that an interrupt is not required (the "no_interrupt" * flag, for use with deep request queues). * * Bulk endpoints can use any size buffers, and can also be used for interrupt * transfers. interrupt-only endpoints can be much less functional. * * NOTE: this is analogous to 'struct urb' on the host side, except that * it's thinner and promotes more pre-allocation. */ struct usb_request { struct usb_ep *ep; void *buf; unsigned length; dma_addr_t dma; struct scatterlist *sg; unsigned num_sgs; unsigned num_mapped_sgs; unsigned stream_id:16; unsigned is_last:1; unsigned no_interrupt:1; unsigned zero:1; unsigned short_not_ok:1; unsigned dma_mapped:1; void (*complete)(struct usb_ep *ep, struct usb_request *req); void *context; struct list_head list; unsigned frame_number; /* ISO ONLY */ int status; unsigned actual; }; /*-------------------------------------------------------------------------*/ /* endpoint-specific parts of the api to the usb controller hardware. * unlike the urb model, (de)multiplexing layers are not required. * (so this api could slash overhead if used on the host side...) * * note that device side usb controllers commonly differ in how many * endpoints they support, as well as their capabilities. */ struct usb_ep_ops { int (*enable) (struct usb_ep *ep, const struct usb_endpoint_descriptor *desc); int (*disable) (struct usb_ep *ep); void (*dispose) (struct usb_ep *ep); struct usb_request *(*alloc_request) (struct usb_ep *ep, gfp_t gfp_flags); void (*free_request) (struct usb_ep *ep, struct usb_request *req); int (*queue) (struct usb_ep *ep, struct usb_request *req, gfp_t gfp_flags); int (*dequeue) (struct usb_ep *ep, struct usb_request *req); int (*set_halt) (struct usb_ep *ep, int value); int (*set_wedge) (struct usb_ep *ep); int (*fifo_status) (struct usb_ep *ep); void (*fifo_flush) (struct usb_ep *ep); }; /** * struct usb_ep_caps - endpoint capabilities description * @type_control:Endpoint supports control type (reserved for ep0). * @type_iso:Endpoint supports isochronous transfers. * @type_bulk:Endpoint supports bulk transfers. * @type_int:Endpoint supports interrupt transfers. * @dir_in:Endpoint supports IN direction. * @dir_out:Endpoint supports OUT direction. */ struct usb_ep_caps { unsigned type_control:1; unsigned type_iso:1; unsigned type_bulk:1; unsigned type_int:1; unsigned dir_in:1; unsigned dir_out:1; }; #define USB_EP_CAPS_TYPE_CONTROL 0x01 #define USB_EP_CAPS_TYPE_ISO 0x02 #define USB_EP_CAPS_TYPE_BULK 0x04 #define USB_EP_CAPS_TYPE_INT 0x08 #define USB_EP_CAPS_TYPE_ALL \ (USB_EP_CAPS_TYPE_ISO | USB_EP_CAPS_TYPE_BULK | USB_EP_CAPS_TYPE_INT) #define USB_EP_CAPS_DIR_IN 0x01 #define USB_EP_CAPS_DIR_OUT 0x02 #define USB_EP_CAPS_DIR_ALL (USB_EP_CAPS_DIR_IN | USB_EP_CAPS_DIR_OUT) #define USB_EP_CAPS(_type, _dir) \ { \ .type_control = !!(_type & USB_EP_CAPS_TYPE_CONTROL), \ .type_iso = !!(_type & USB_EP_CAPS_TYPE_ISO), \ .type_bulk = !!(_type & USB_EP_CAPS_TYPE_BULK), \ .type_int = !!(_type & USB_EP_CAPS_TYPE_INT), \ .dir_in = !!(_dir & USB_EP_CAPS_DIR_IN), \ .dir_out = !!(_dir & USB_EP_CAPS_DIR_OUT), \ } /** * struct usb_ep - device side representation of USB endpoint * @name:identifier for the endpoint, such as "ep-a" or "ep9in-bulk" * @ops: Function pointers used to access hardware-specific operations. * @ep_list:the gadget's ep_list holds all of its endpoints * @caps:The structure describing types and directions supported by endpoint. * @enabled: The current endpoint enabled/disabled state. * @claimed: True if this endpoint is claimed by a function. * @maxpacket:The maximum packet size used on this endpoint.

Called in_interrupt; this may not sleep.

May be called in_interrupt. * @resume: Invoked on USB resume. May be called in_interrupt. * @reset: Invoked on USB bus reset. It is mandatory for all gadget drivers * and should be called in_interrupt. * @driver: Driver model state for this driver. * @udc_name: A name of UDC this driver should be bound to.

Drivers must make sure the endpoint * descriptors match any hardware constraints. Some hardware also constrains * other descriptors. (The pxa250 allows only configurations 1, 2, or 3). * * The driver's setup() callback must also implement set_configuration, * and should also implement set_interface, get_configuration, and * get_interface.

Thus, * static_branch_inc() can be thought of as a 'make more true' and * static_branch_dec() as a 'make more false'. * * Since this relies on modifying code, the branch modifying functions * must be considered absolute slow paths (machine wide synchronization etc.). * OTOH, since the affected branches are unconditional, their runtime overhead * will be absolutely minimal, esp. in the default (off) case where the total * effect is a single NOP of appropriate size. The on case will patch in a jump * to the out-of-line block. * * When the control is directly exposed to userspace, it is prudent to delay the * decrement to avoid high frequency code modifications which can (and do) * cause significant performance degradation. Struct static_key_deferred and * static_key_slow_dec_deferred() provide for this. * * Lacking toolchain and or architecture support, static keys fall back to a * simple conditional branch. * * Additional babbling in: Documentation/staging/static-keys.rst */ #ifndef __ASSEMBLY__ #include <linux/types.h> #include <linux/compiler.h> extern bool static_key_initialized; #define STATIC_KEY_CHECK_USE(key) WARN(!static_key_initialized, \ "%s(): static key '%pS' used before call to jump_label_init()", \ __func__, (key)) #ifdef CONFIG_JUMP_LABEL struct static_key { atomic_t enabled; /* * Note: * To make anonymous unions work with old compilers, the static * initialization of them requires brackets.

There are * more than twice as many slots as event channels. * * Each PaRAM set describes a sequence of transfers, either for one large * buffer or for several discontiguous smaller buffers. An EDMA transfer * is driven only from a channel, which performs the transfers specified * in its PaRAM slot until there are no more transfers.

Updates to a * name will modify the trampoline's branch destination. * * If the arch has CONFIG_HAVE_STATIC_CALL_INLINE, then the call sites * themselves will be patched at runtime to call the functions directly, * rather than calling through the trampoline. This requires objtool or a * compiler plugin to detect all the static_call() sites and annotate them * in the .static_call_sites section. * * * Notes on NULL function pointers: * * Static_call()s support NULL functions, with many of the caveats that * regular function pointers have. * * Clearly calling a NULL function pointer is 'BAD', so too for * static_call()s (although when HAVE_STATIC_CALL it might not be immediately * fatal). A NULL static_call can be the result of: * * DECLARE_STATIC_CALL_NULL(my_static_call, void (*)(int)); * * which is equivalent to declaring a NULL function pointer with just a * typename: * * void (*my_func_ptr)(int arg1) = NULL; * * or using static_call_update() with a NULL function. In both cases the * HAVE_STATIC_CALL implementation will patch the trampoline with a RET * instruction, instead of an immediate tail-call JMP. HAVE_STATIC_CALL_INLINE * architectures can patch the trampoline call to a NOP. * * In all cases, any argument evaluation is unconditional. Unlike a regular * conditional function pointer call: * * if (my_func_ptr) * my_func_ptr(arg1) * * where the argument evaludation also depends on the pointer value. * * When calling a static_call that can be NULL, use: * * static_call_cond(name)(arg1); * * which will include the required value tests to avoid NULL-pointer * dereferences. * * To query which function is currently set to be called, use: * * func = static_call_query(name); * * * DEFINE_STATIC_CALL_RET0 / __static_call_return0: * * Just like how DEFINE_STATIC_CALL_NULL() / static_call_cond() optimize the * conditional void function call, DEFINE_STATIC_CALL_RET0 / * __static_call_return0 optimize the do nothing return 0 function. * * This feature is strictly UB per the C standard (since it casts a function * pointer to a different signature) and relies on the architecture ABI to * make things work.

This avoids wrapping the * counter and causing 'spurious' use-after-free issues. In order to avoid the * cost associated with introducing cmpxchg() loops into all of the saturating * operations, we temporarily allow the counter to take on an unchecked value * and then explicitly set it to REFCOUNT_SATURATED on detecting that underflow * or overflow has occurred. Although this is racy when multiple threads * access the refcount concurrently, by placing REFCOUNT_SATURATED roughly * equidistant from 0 and INT_MAX we minimise the scope for error: * * INT_MAX REFCOUNT_SATURATED UINT_MAX * 0 (0x7fff_ffff) (0xc000_0000) (0xffff_ffff) * +--------------------------------+----------------+----------------+ * <---------- bad value! ----------> * * (in a signed view of the world, the "bad value" range corresponds to * a negative counter value). * * As an example, consider a refcount_inc() operation that causes the counter * to overflow: * * int old = atomic_fetch_add_relaxed(r); * // old is INT_MAX, refcount now INT_MIN (0x8000_0000) * if (old < 0) * atomic_set(r, REFCOUNT_SATURATED); * * If another thread also performs a refcount_inc() operation between the two * atomic operations, then the count will continue to edge closer to 0. If it * reaches a value of 1 before /any/ of the threads reset it to the saturated * value, then a concurrent refcount_dec_and_test() may erroneously free the * underlying object. * Linux limits the maximum number of tasks to PID_MAX_LIMIT, which is currently * 0x400000 (and can't easily be raised in the future beyond FUTEX_TID_MASK). * With the current PID limit, if no batched refcounting operations are used and * the attacker can't repeatedly trigger kernel oopses in the middle of refcount * operations, this makes it impossible for a saturated refcount to leave the * saturation range, even if it is possible for multiple uses of the same * refcount to nest in the context of a single task: * * (UINT_MAX+1-REFCOUNT_SATURATED) / PID_MAX_LIMIT = * 0x40000000 / 0x400000 = 0x100 = 256 * * If hundreds of references are added/removed with a single refcounting * operation, it may potentially be possible to leave the saturation range; but * given the precise timing details involved with the round-robin scheduling of * each thread manipulating the refcount and the need to hit the race multiple * times in succession, there doesn't appear to be a practical avenue of attack * even if using refcount_add() operations with larger increments. * * Memory ordering * =============== * * Memory ordering rules are slightly relaxed wrt regular atomic_t functions * and provide only what is strictly required for refcounts. * * The increments are fully relaxed; these will not provide ordering. The * rationale is that whatever is used to obtain the object we're increasing the * reference count on will provide the ordering. For locked data structures, * its the lock acquire, for RCU/lockless data structures its the dependent * load. * * Do note that inc_not_zero() provides a control dependency which will order * future stores against the inc, this ensures we'll never modify the object * if we did not in fact acquire a reference. * * The decrements will provide release order, such that all the prior loads and * stores will be issued before, it also provides a control dependency, which * will order us against the subsequent free(). * * The control dependency is against the load of the cmpxchg (ll/sc) that * succeeded. This means the stores aren't fully ordered, but this is fine * because the 1->0 transition indicates no concurrency. * * Note that the allocator is responsible for ordering things between free() * and alloc(). * * The decrements dec_and_test() and sub_and_test() also provide acquire * ordering on success. * */ #ifndef _LINUX_REFCOUNT_H #define _LINUX_REFCOUNT_H #include <linux/atomic.h> #include <linux/bug.h> #include <linux/compiler.h> #include <linux/limits.h> #include <linux/spinlock_types.h> struct mutex; /** * typedef refcount_t - variant of atomic_t specialized for reference counts * @refs: atomic_t counter field * * The counter saturates at REFCOUNT_SATURATED and will not move once * there.
