-Subject: ath10k: search DT for qcom,ath10k-calibration-variant
-
-Board Data File (BDF) is loaded upon driver boot-up procedure. The right
-board data file is identified on QCA4019 using bus, bmi-chip-id and
-bmi-board-id.
-
-The problem, however, can occur when the (default) board data file cannot
-fulfill with the vendor requirements and it is necessary to use a different
-board data file.
-
-This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
-Something similar has to be provided for systems without SMBIOS but with
-device trees. No solution was specified by QCA and therefore a new one has
-to be found for ath10k.
-
-The device tree requires addition strings to define the variant name
-
- wifi@a000000 {
- status = "okay";
- qcom,ath10k-calibration-variant = "RT-AC58U";
- };
-
- wifi@a800000 {
- status = "okay";
- qcom,ath10k-calibration-variant = "RT-AC58U";
- };
-
-This would create the boarddata identifiers for the board-2.bin search
-
- * bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
- * bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

-Subject: [PATCH] ath10k: suppress "Unknown eventid: 36925" warnings
-
-FW has Smart Logging feature enabled by default for detecting failures
-and processing FATAL_CONDITION_EVENTID (36925 - 0x903D) back to host.
-
-Since ath10k doesn't implement the Smart Logging and FATAL CONDITION
-EVENT processing yet, suppressing the unknown event ID warning by moving
-this under ATH10K_DBG_WMI.
-
-Simulated the same issue by having associated STA powered off when
-ping flood was running from AP backbone. This triggerd STA KICKOUT
-in AP followed by FATAL CONDITION event 36925.
-
-Issue was reproduced and verified in below DUT
-------------------------------------------------
-AP mode of OpenWRT QCA9984 running 6.0.8 with FW ver 10.4-3.5.3-00053

-This reverts commit fb47ada8dc3c30c8e7b415da155742b49536c61e.
-
-In some situations when we set TXOP_BACKOFF, the probe frame is
-not sent at all. What it worse then sending probe frame as part
-of AMPDU and can degrade 11n performance to 11g rates.

-Subject: [PATCH] ath10k: search all IEs for variant before falling back
-Date: Wed, 21 Feb 2018 11:43:39 -0500
-
-commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file
-extension") added a feature to ath10k that allows Board Data File
-(BDF) conflicts between multiple devices that use the same device IDs
-but have different calibration requirements to be resolved by allowing
-a "variant" string to be stored in SMBIOS [and later device tree, added
-by commit d06f26c5c8a4 ("ath10k: search DT for qcom,ath10k-calibration-
-variant")] that gets appended to the ID stored in board-2.bin.
-
-This original patch had a regression, however. Namely that devices with
-a variant present in SMBIOS that didn't need custom BDFs could no longer
-find the default BDF, which has no variant appended. The patch was
-reverted and re-applied with a fix for this issue in commit 1657b8f84ed9
-("search SMBIOS for OEM board file extension").
-
-But the fix to fall back to a default BDF introduced another issue: the
-driver currently parses IEs in board-2.bin one by one, and for each one
-it first checks to see if it matches the ID with the variant appended.
-If it doesn't, it checks to see if it matches the "fallback" ID with no
-variant. If a matching BDF is found at any point during this search, the
-search is terminated and that BDF is used. The issue is that it's very
-possible (and is currently the case for board-2.bin files present in the
-ath10k-firmware repository) for the default BDF to occur in an earlier
-IE than the variant-specific BDF. In this case, the current code will
-happily choose the default BDF even though a better-matching BDF is
-present later in the file.
-
-This patch fixes the issue by first searching the entire file for the ID
-with variant, and searching for the fallback ID only if that search
-fails. It also includes some code cleanup in the area, as
-ath10k_core_fetch_board_data_api_n() no longer does its own string
-mangling to remove the variant from an ID, instead leaving that job to a
-new flag passed to ath10k_core_create_board_name().
-
-I've tested this patch on a QCA4019 and verified that the driver behaves
-correctly for 1) both fallback and variant BDFs present, 2) only fallback
-BDF present, and 3) no matching BDFs present.
-
-Fixes: 1657b8f84ed9 ("ath10k: search SMBIOS for OEM board file extension")

-drivers/net/wireless/ath/ath10k/pci.c:3428:8: error: implicit
-declaration of function 'ath10k_pci_resume'
-[-Werror=implicit-function-declaration]
-
-These are caused by the combination of the following two commits:
-
-6af1de2e4ec4 ("ath10k: mark PM functions as __maybe_unused")
-96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but
-disabled")
-
-Both build fine on their own.
-
-But now that ath10k_pci_pm_{suspend,resume}() is compiled
-unconditionally, we should also compile ath10k_pci_{suspend,resume}()
-unconditionally.
-
-And drop the #ifdef around ath10k_pci_hif_{suspend,resume}() too; they
-are trivial (empty), so we're not saving much space by compiling them
-out. And the alternatives would be to sprinkle more __maybe_unused, or
-spread the #ifdef's further.
-
-Build tested with the following combinations:
-CONFIG_PM=y && CONFIG_PM_SLEEP=y
-CONFIG_PM=y && CONFIG_PM_SLEEP=n
-CONFIG_PM=n
-
-Fixes: 96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but disabled")
-Fixes: 096ad2a15fd8 ("Merge branch 'ath-next'")

-Subject: [PATCH] mac80211: properly free requested-but-not-started TX agg
- sessions
-
-When deleting a station or otherwise tearing down all aggregation
-sessions, make sure to delete requested but not yet started ones,
-to avoid the following scenario:
-
- * session is requested, added to tid_start_tx[]
- * ieee80211_ba_session_work() runs, gets past BLOCK_BA check
- * ieee80211_sta_tear_down_BA_sessions() runs, locks &sta->ampdu_mlme.mtx,
- e.g. while deleting the station - deleting all active sessions
- * ieee80211_ba_session_work() continues since tear down flushes it, and
- calls ieee80211_tx_ba_session_handle_start() for the new session, arms
- the timer for it
- * station deletion continues to __cleanup_single_sta() and frees the
- session struct, while the timer is armed

-The firmware uses a mailbox to communicate to the host what is going
-on. In the driver we validate the bit received. Various people seen
-the following message:
-
- brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

-Bit 4 is cause of this message, but this actually indicates the firmware
-has halted. Handle this bit by giving a more meaningful error message.

-Subject: [PATCH] brcmfmac: add CLM download support
-
-The firmware for brcmfmac devices includes information regarding
-regulatory constraints. For certain devices this information is kept
-separately in a binary form that needs to be downloaded to the device.
-This patch adds support to download this so-called CLM blob file. It
-uses the same naming scheme as the other firmware files with extension
-of .clm_blob.
-
-The CLM blob file is optional. If the file does not exist, the download
-process will be bypassed. It will not affect the driver loading.

-Subject: [PATCH] brcmfmac: change driver unbind order of the sdio function
- devices
-
-In the function brcmf_sdio_firmware_callback() the driver is
-unbound from the sdio function devices in the error path.
-However, the order in which it is done resulted in a use-after-free
-issue (see brcmf_ops_sdio_remove() in bcmsdh.c). Hence change
-the order and first unbind sdio function #2 device and then
-unbind sdio function #1 device.

-
-For legacy chips without CLM blob files, kernel with user helper function
-returns -EAGAIN when we request_firmware(), and then driver got failed
-when bringing up legacy chips. We expect the CLM blob file for legacy chip
-is not existence in firmware path, but the -ENOENT error is transferred to
--EAGAIN in firmware_class.c with user helper.
-Because of that, we continue with CLM data currently present in firmware
-if getting error from doing request_firmware().

-Subject: [PATCH] brcmfmac: Split brcmf_sdiod_regrw_helper() up.
-
-This large function is concealing a LOT of obscure logic about
-how the hardware functions. Time to split it up.
-
-This first patch splits the function into two pieces - read and write,
-doing away with the rw flag in the process.

-
-Unlikely to be a problem, but brcmf_sdiod_regrl() is
-not symmetric with brcmf_sdiod_regrb() in initializing
-the data value on stack. Fix that.

-Subject: [PATCH] brcmfmac: Rename / replace old IO functions with simpler
- ones.
-
-Primarily this patch removes:
-
-brcmf_sdiod_f0_writeb()
-brcmf_sdiod_reg_write()
-brcmf_sdiod_reg_read()
-
-Since we no longer use the quirky method of deciding which function to
-address via the address being accessed, take the opportunity to rename
-some IO functions more in line with common kernel code. We also convert
-those that map directly to sdio_{read,write}*() to macros.

-Subject: [PATCH] brcmfmac: Remove brcmf_sdiod_addrprep()
-
-This function has become trivial enough that it may as well be pushed into
-its callers, which has the side-benefit of clarifying what's going on.
-
-Remove it, and rename brcmf_sdiod_set_sbaddr_window() to
-brcmf_sdiod_set_backplane_window() as it's easier to understand.

-Subject: [PATCH] brcmfmac: enlarge buffer size of caps to 512 bytes
-
-The buffer size of return of cap iovar is greater than 256 bytes in some
-firmwares. For instance, the return size of cap iovar is 271 bytes in 4373
-13.10.246.79 firmare. It makes feature capability parsing failed because
-caps buffer is default value.
-So we enlarge caps buffer size to 512 bytes and add the error print for
-cap iovar error.

-Subject: [PATCH] brcmfmac: Remove func0 from function array
-
-func0 is not provided by the mmc stack as a function when probing.
-Instead providing specific access functions to read/write it.
-
-This prepares for a patch to remove the actual array entry itself.

-Subject: [PATCH] brcmfmac: More efficient and slightly easier to read fixup
- for 4339 chips
-
-Its more efficient to test the register we're interested in first,
-potentially avoiding two more comparisons, and therefore always avoiding
-one comparison per call on all other chips.

-This ensures that mac80211 allocated management frames are properly
-aligned, which makes copying them more efficient.
-For instance, mt76 uses iowrite32_copy to copy beacon frames to beacon

-Misaligned 32-bit accesses cause CPU exceptions on MIPS and should be

-Subject: [PATCH] brcmfmac: assure bcdc dcmd api does not return value > 0
-
-The protocol layer api defines callbacks for dongle commands.
-Although not really well documented these should only return an
-error code in case of an error, or 0 upon success. In the bcdc
-protocol it can return value above 0 and we carry a fix in the
-caller of the protocol layer api. This patch makes it adhere to
-the intent of the api as described above.

-Subject: [PATCH] brcmfmac: separate firmware errors from i/o errors
-
-When using the firmware api it can fail simply because firmware does
-not like the request or it fails due to issues in the host interface.
-Currently, there is only a single error code which is confusing. So
-adding a parameter to pass the firmware error separately and in case
-of a firmware error always return -EBADE to user-space.

-Subject: [PATCH] brcmfmac: fix P2P_DEVICE ethernet address generation
-
-The firmware has a requirement that the P2P_DEVICE address should
-be different from the address of the primary interface. When not
-specified by user-space, the driver generates the MAC address for
-the P2P_DEVICE interface using the MAC address of the primary
-interface and setting the locally administered bit. However, the MAC
-address of the primary interface may already have that bit set causing
-the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this
-by using a random address instead to determine the P2P_DEVICE address.

-Subject: [PATCH] brcmfmac: drop Inter-Access Point Protocol packets by default
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Testing brcmfmac with more recent firmwares resulted in AP interfaces
-not working in some specific setups. Debugging resulted in discovering
-support for IAPP in Broadcom's firmwares.
-
-Older firmwares were only generating 802.11f frames. Newer ones like:
-1) 10.10 (TOB) (r663589)
-2) 10.10.122.20 (r683106)
-for 4366b1 and 4366c0 respectively seem to also /respect/ 802.11f frames
-in the Tx path by performing a STA disassociation.
-
-This obsoleted standard and its implementation is something that:
-1) Most people don't need / want to use
-2) Can allow local DoS attacks
-3) Breaks AP interfaces in some specific bridge setups
-
-To solve issues it can cause this commit modifies brcmfmac to drop IAPP
-packets. If affects:
-1) Rx path: driver won't be sending these unwanted packets up.
-2) Tx path: driver will reject packets that would trigger STA
- disassociation perfromed by a firmware (possible local DoS attack).
-
-It appears there are some Broadcom's clients/users who care about this
-feature despite the drawbacks. They can switch it on using a new module
-param.
-
-This change results in only two more comparisons (check for module param
-and check for Ethernet packet length) for 99.9% of packets. Its overhead
-should be very minimal.

-In case of a linux error brcmf_fil_cmd_data() blurts an error message
-in which the error code is translated to an error string. However, it
-maps it to a firmware error string which should not happen. Simply

-
-The chip id can either be four or five digits. For the chip name either
-the hexadecimal value needs to be taken (four digits) or the decimal
-value (five digits). The function brcmf_chip_name() does this conversion
-so use it to store the name in driver revision info.

-Subject: [PATCH] brcmfmac: allocate struct brcmf_pub instance using
- wiphy_new()
-
-Rework the driver so the wiphy instance holds the main driver information
-in its private buffer. Previously it held struct brcmf_cfg80211_info
-instance so a bit of reorg was needed. This was done so that the wiphy
-name or its parent device can be shown in debug output.

-From: Arend Van Spriel <arend.vanspriel@broadcom.com>
-Date: Thu, 22 Mar 2018 21:28:27 +0100
-Subject: [PATCH] brcmfmac: introduce brcmf_fw_alloc_request() function
-
-The function brcmf_fw_alloc_request() takes a list of required files
-and allocated the struct brcmf_fw_request instance accordingly. The
-request can be modified by the caller before being passed to the
-brcmf_fw_request_firmwares() function.

-Subject: [PATCH] brcmfmac: add extension to .get_fwname() callbacks
-
-This changes the bus layer api by having the caller provide an
-extension. With this the callback can use brcmf_fw_alloc_request()
-to get the needed firmware name.

-
-Revision 7 of PCIe dongle interface increases the item size of tx and rx
-complete rings to accommodate extra payload for new feature. This patch
-simply bump up the size of these two rings without adding the support
-for utilizing the new space. This makes brcmfmac compatible with rev7

-Subject: [PATCH] brcmfmac: Add support for bcm43364 wireless chipset
-
-Add support for the BCM43364 chipset via an SDIO interface, as used in
-e.g. the Murata 1FX module.
-
-The BCM43364 uses the same firmware as the BCM43430 (which is already
-included), the only difference is the omission of Bluetooth.
-
-However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS
-of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't
-load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place
-triggers the brcmfmac driver to load, and then correctly use the
-firmware file 'brcmfmac43430-sdio.bin'.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-brcmfmac is a FullMAC driver and it implements/uses cfg80211 interface
-for stations management. At the same time it doesn't receive or pass up
-management frames.
-
-This flag indicates that authenticator doesn't have to subscribe to or
-handle management frames. Some authenticators (e.g. hostapd) were
-working with brcmfmac thanks to some extra assumptions. This commit
-clears up the situation.

- devices
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-NVRAM is designed to work with Broadcom's SDK Linux kernel which fakes
-PCI domain 0 for all internal MMIO devices. Since official Linux kernel
-uses platform devices for that purpose there is a mismatch in numbering
-PCI domains.
-
-There used to be a fix for that problem but it was accidentally dropped
-during the last firmware loading rework. That resulted in brcmfmac not
-being able to extract device specific NVRAM content and all kind of
-calibration problems.

-
-Check for that entry and store internally info about monitor mode

-Subject: [PATCH] brcmfmac: handle msgbuf packets marked with monitor mode flag
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-New Broadcom firmwares mark monitor mode packets using a newly defined
-bit in the flags field. Use it to filter them out and pass to the
-monitor interface. These defines were found in bcmmsgbuf.h from SDK.
-
-As not every firmware generates radiotap header this commit introduces
-BRCMF_FEAT_MONITOR_FMT_RADIOTAP flag. It has to be has based on firmware
-capabilities. If not present brcmf_netif_mon_rx() will assume packet is
-a raw 802.11 frame and will prepend it with an empty radiotap header.
-
-This new code is limited to the msgbuf protocol at this point. Adding
-support for SDIO/USB devices will require some extra work (possibly a
-new firmware release).

-Subject: [PATCH] brcmfmac: update STA info struct to the v5
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-That struct is used when querying firmware for the STA. It seem is has
-been changing during the time. Luckily its format seems to be backward
-compatible starting with v2 (the only breakage was v1 -> v2).
-
-The version that was supported by brcmfmac so far was v4. It was what
-43602a1 and 4366b1 firmwares (7.35.177.56 and 10.10.69.3309 accordingly)
-were using. It also seems to be used by early 4366c0 firmwares
-(10.10.69.6908 and 10.10.69.69017).
-
-The problem appears when switching to the 10.10.122.20 firmware. It uses
-v5 and instead of falling back to v4 when submitted buffer isn't big
-enough it fallbacks to the v3.
-
-To receive all v4 specific info with the newest firmware we have to
-submit a struct (buffer) that matches v5.

-Subject: [PATCH] brcmfmac: specify some features per firmware version
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some features supported by firmware aren't advertised and there is no
-way for a driver to query them. This includes e.g. monitor mode details.
-
-Most firmwares support monitor interface but only the latest ones
-/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
-reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
-but "it only indicates the core part of the stack supports").
-
-Similarly support for tagging monitor frames and building radiotap
-headers can't be reliably detected for all firmwares.
-
-This commit adds table that allows mapping features to firmware version.
-It adds mappings for 43602a1 and 4366b1 firmwares from
-linux-firmware.git. Both were confirmed to be passing monitor frames.

-Subject: [PATCH] mac80211: add NEED_ALIGNED4_SKBS hw flag
-
-HW/driver should set NEED_ALIGNED4_SKBS flag in case
-require aligned skbs to four-byte boundaries.
-This affect only TX direction.
-
-Padding is added after ieee80211_hdr, before IV/LLC.
-
-Before we have to do memmove(hdrlen) twice in the
-dirver. Once before we pass this to HW and next
-in tx completion (to be sure monitor will report
-this tx frame correctly).
-
-With this patch we can skip this memmove() and save CPU.
-
-Currently this was tested with ath9k, both hw/sw crypt for
-wep/tkip/ccmp.

-Subject: [PATCH] ath9k_hw: fix channel maximum power level test
-
-The tx power applied by set_txpower is limited by the CTL (conformance
-test limit) entries in the EEPROM. These can change based on the user
-configured regulatory domain.
-Depending on the EEPROM data this can cause the tx power to become too
-limited, if the original regdomain CTLs impose lowr limits than the CTLs
-of the user configured regdomain.
-
-To fix this issue, set the initial channel limits without any CTL
-restrictions and only apply the CTL at run time when setting the channel
-and the real tx power.

-Subject: [PATCH] cfg80211: use only 1Mbps for basic rates in mesh
-
-Mesh used to use the mandatory rates as basic rates, but we got
-the calculation of mandatory rates wrong until some time ago.
-Fix this this broke interoperability with older versions since
-now more basic rates are required, and thus the MBSS isn't the
-same and the network stops working.
-
-Fix this by simply using only 1Mbps as the basic rate in 2.4GHz.
-Since the changed mandatory rates only affected 2.4GHz, this is
-all we need to make it work again.
-
-Reported-and-tested-by: Matthias Schiffer <mschiffer@universe-factory.net>
-Fixes: 1bd773c077de ("wireless: set correct mandatory rate flags")

-Subject: [PATCH] mac80211: minstrel: reduce minstrel_mcs_groups size
-
-By storing a shift value for all duration values of a group, we can
-reduce precision by a neglegible amount to make it fit into a u16 value.
-This improves cache footprint and reduces size:
-
-Before:
- text data bss dec hex filename
- 10024 116 0 10140 279c rc80211_minstrel_ht.o
-
-After:
- text data bss dec hex filename
- 9368 116 0 9484 250c rc80211_minstrel_ht.o
-
-Signed-off-by: Felix Fietkau <nbd@nbd.name>

-Subject: [PATCH] ath9k: Protect queue draining by rcu_read_lock()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When ath9k was switched over to use the mac80211 intermediate queues,
-node cleanup now drains the mac80211 queues. However, this call path is
-not protected by rcu_read_lock() as it was previously entirely internal
-to the driver which uses its own locking.
-
-This leads to a possible rcu_dereference() without holding
-rcu_read_lock(); but only if a station is cleaned up while having
-packets queued on the TXQ. Fix this by adding the rcu_read_lock() to the
-caller in ath9k.
-
-Fixes: 50f08edf9809 ("ath9k: Switch to using mac80211 intermediate software queues.")

-Long/short preamble selection cannot be sampled separately, since it

-currently not used preamble modes are not counted in the statistics,

-Subject: [PATCH] mac80211: fix memory accounting with A-MSDU aggregation
-
-fq uses skb->truesize for memory usage tracking. Increments/decrements
-are done on enqueue/dequeue.
-When A-MSDU aggregation is performed on tx side, the packet is
-aggregated with the last packet in the queue belonging to the same flow.
-There are multiple bugs here:
-- The truesize field of the aggregated packet isn't updated, so memory
-usage is underestimated
-- fq->memory_usage isn't adjusted.
-
-Because of the combination of both bugs, this only causes tx issues in
-rare cases, mainly when the A-MSDU head needs to be reallocated.
-
-Fix this by adjusting both truesize of the A-MSDU head and adding the
-truesize delta to fq->memory_usage.

-Subject: [PATCH v2] cfg80211: initialize sinfo in cfg80211_get_station
-
-Most of the implementations behind cfg80211_get_station will not initialize
-sinfo to zero before manipulating it. For example, the member "filled",
-which indicates the filled in parts of this struct, is often only modified
-by enabling certain bits in the bitfield while keeping the remaining bits
-in their original state. A caller without a preinitialized sinfo.filled can
-then no longer decide which parts of sinfo were filled in by
-cfg80211_get_station (or actually the underlying implementations).
-
-cfg80211_get_station must therefore take care that sinfo is initialized to
-zero. Otherwise, the caller may tries to read information which was not
-filled in and which must therefore also be considered uninitialized. In
-batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
-may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
-switch to non-optimal neighbors for certain destinations.

-Subject: [PATCH] ath10k: Fix kernel panic while using worker
- (ath10k_sta_rc_update_wk)
-
-When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
-(ieee80211_sta) delete will trigger the kernel panic.
-
-This problem arise in AP + Mesh configuration, Where the current node AP VAP
-and neighbor node mesh VAP MAC address are same. When the current mesh node
-try to establish the mesh link with neighbor node, driver peer creation for
-the neighbor mesh node fails due to duplication MAC address. Already the AP
-VAP created with same MAC address.
-
-It is caused by the following scenario steps.
-
-Steps:
-1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
- fails to do the state change for a station from IEEE80211_STA_NOTEXIST
- to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
- called from ieee80211_add_station() to handle the new station
- (neighbor mesh node) request from the wpa_supplicant.
-2. Concurrently ath10k receive the sta_rc_update callback notification from
- the mesh_neighbour_update() to handle the beacon frames of the above
- neighbor mesh node. since its atomic callback, ath10k driver queue the
- work (ath10k_sta_rc_update_wk) to handle rc update.
-3. Due to driver sta_state callback fails (step 1), mac80211 free the station
- object.
-4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
- the station object which is already deleted. so it will trigger kernel
- panic.
-
-Added the peer exist check in sta_rc_update callback before queue the work.

-Subject: [PATCH] ath10k: fix kernel panic while reading tpc_stats
-
-When attempt to read tpc_stats for the chipsets which support
-more than 3 tx chain will trigger kernel panic(kernel stack is corrupted)
-due to writing values on rate_code array out of range.
-This patch changes the array size depends on the WMI_TPC_TX_N_CHAIN and
-added check to avoid write values on the array if the num tx chain
-get in tpc config event is greater than WMI_TPC_TX_N_CHAIN.
-
-Tested on QCA9984 with firmware-5.bin_10.4-3.5.3-00057

-Subject: [PATCH] ath: add support to get the detected radar specifications
-
-This enables ath10k/ath9k drivers to collect the specifications of the
-radar type once it is detected by the dfs pattern detector unit.
-Usage of the collected info is specific to driver implementation.
-For example, collected radar info could be used by the host driver
-to send to co-processors for additional processing/validation.
-
-Note: 'radar_detector_specs' data containing the specifications of
-different radar types which was private within dfs_pattern_detector/
-dfs_pri_detector is now shared with drivers as well for making use
-of this information.

-Subject: [PATCH] ath10k: DFS Host Confirmation
-
-In the 10.4-3.6 firmware branch there's a new DFS Host confirmation
-feature which is advertised using WMI_SERVICE_HOST_DFS_CHECK_SUPPORT flag.
-
-This new features enables the ath10k host to send information to the
-firmware on the specifications of detected radar type. This allows the
-firmware to validate if the host's radar pattern detector unit is
-operational and check if the radar information shared by host matches
-the radar pulses sent as phy error events from firmware. If the check
-fails the firmware won't allow use of DFS channels on AP mode when using
-FCC regulatory region.
-
-Hence this patch is mandatory when using a firmware from 10.4-3.6 branch.
-Else, DFS channels on FCC regions cannot be used.
-
-Supported Chipsets : QCA9984/QCA9888/QCA4019
-Firmware Version : 10.4-3.6-00104

-Subject: [PATCH] ath10k: fix spectral scan for QCA9984 and QCA9888 chipsets
-
-The spectral scan has been always broken on QCA9984 and QCA9888.
-
-Introduce a hardware parameter 'spectral_bin_offset' to resolve this issue for
-QCA9984 and QCA9888 chipsets. For other chipsets, the hardware parameter
-'spectral_bin_offset' is zero so that existing behaviour is retained as it is.
-
-In QCA9984 and QCA9888 chipsets, hardware param value 'spectral_bin_discard'
-is 12 bytes. This 12 bytes is derived as the sum of segment index (4 bytes),
-extra bins before the actual data (4 bytes) and extra bins after the actual
-data (4 bytes). Always discarding (12 bytes) happens at end of the samples and
-incorrect samples got dumped, so that user can find incorrect arrangement
-samples in spectral scan dump.
-
-To fix this issue, we have to discard first 8 bytes and last 4 bytes in every
-samples, so totally 12 bytes are discarded. In every sample we need to consider
-the offset while taking the actual spectral data. For QCA9984, QCA9888 the
-offset is 8 bytes (segment index + extra bins before actual data).
-
-Hardware tested: QCA9984 and QCA9888
-Firmware tested: 10.4-3.5.3-00053

-
-Tx99 is typically configured via a monitor mode interface, which does
-not get added to the driver as a vif. Since the code currently expects
-a configured virtual interface for tx99, enabling tx99 via debugfs fails.
-Since the vif is not needed anyway, remove all checks for it.

-Subject: [PATCH] ath10k: Don't initialize devices asynchronously
-
-OpenWrt requires all PHYs to be initialized to create the configuration files
-during bootup. ath10k violates this because it delays the creation of the PHY
-to a not well defined point in the future.
-
-Forcing the work to be done immediately works around this problem but may also
-delay the boot when firmware images cannot be found.

-current handling of peer_bw_rxnss_override parameter is based on guessing the VHT160/8080 capability by rx rate. this is wrong and may lead
-to a non initialized peer_bw_rxnss_override parameter which is required since VHT160 operation mode only supports 2x2 chainmasks in addition the original code
-initialized the parameter with wrong masked values.
-This patch uses the peer phymode and peer nss information for correct initialisation of the peer_bw_rxnss_override parameter.
-if this peer information is not available, we initialize the parameter by minimum nss which is suggested by QCA as temporary workaround according
-to the QCA sourcecodes.

-v2: remove debug messages
-v3: apply some cosmetics, update documentation
-v4: fix compile warning and truncate nss to maximum of 2x2 since current chipsets only support 2x2 at vht160
-v5: handle maximum nss for chipsets supportig vht160 with 1x1 only
-v7: use more simple code variant and take care about hw/sw chainmask configuration
-v8: fix some code style issues

-starting with firmware 10.4.3.4.x series QCA changed the handling of the channel property band_center_freq1 and band_center_freq2 in vht160 operation mode
-likelly for backward compatiblity with vht80 only capable clients.
-this patch adjusts the handling to get vht160 to work again with official qca firmwares newer than 3.3
-consider that this patch will not work with older firmwares anymore. to avoid undefined behaviour this we disable vht160 capability for outdated firmwares

-v2: fix trailing whitespace issue and fix some typos within the commit note

-
-Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based
-chipsets with on chipset connected led's using WMI Firmware API. The LED
-device will get available named as "ath10k-phyX" at sysfs and can be controlled
-with various triggers. adds also debugfs interface for gpio control.
-
-This patch is specific for OpenWRt base, as is use old backported package
-with old wireless source. Support for QCA9984 is removed and a simbol
-is added to local-simbol file to export the actually compile the code
-with the ATH10K_LEDS simbol.

----
-
-v13:
-
-* only compile tested!
-
-* fix all checkpatch warnings
-
-* fix commit log
-
-* sizeof(struct ath10k_gpiocontrol) -> sizeof(*gpio)
-
-* unsigned -> unsigned int
-
-* remove GPIOLIB code, that should be added in a separate patch
-
-* rename gpio.c to leds.c
-
-* add leds.h
-
-* rename some functions:
-
- ath10k_attach_led() -> ath10k_leds_register()
- ath10k_unregister_led() -> ath10k_leds_unregister()
- ath10k_reset_led_pin() -> ath10k_leds_start()
-
-* call ath10k_leds_unregister() before ath10k_thermal_unregister() to preserve ordering
-
-* call ath10k_leds_start() only from ath10k_core_start() and not from mac.c
-
-* rename struct ath10k_gpiocontrol as anonymous function under struct
- ath10k::leds, no need for memory allocation
-
-* merge ath10k_add_led() to ath10k_attach_led(), which is it's only caller
-
-* remove #if IS_ENABLED() checks from most of places, memory savings from those were not worth it
-
-* Kconfig help text improvement and move it lower in the menu, also don't enable it by default
-
-* switch to set_brightness_blocking() so that the callback can sleep,
- then no need to use ath10k_wmi_cmd_send_nowait() and can take mutex
- to access ar->state
-
-* don't touch ath10k_wmi_pdev_get_temperature()
-
-* as QCA6174/QCA9377 are not (yet) supported don't add the command to WMI-TLV interface
-
-* remove debugfs interface, that should be added in another patch
-
-* cleanup includes

-Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
-
-Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
-the RX and TX path. These filtered channel can in theory still be used by
-the hardware but the signal strength is reduced so much that it makes no
-sense.
-
-There is already a DT property to limit the available channels but ath10k
-has to manually call this functionality to limit the currrently set wiphy
-channels further.

+Subject: [PATCH] ath9k_hw: fix channel maximum power level test
+
+The tx power applied by set_txpower is limited by the CTL (conformance
+test limit) entries in the EEPROM. These can change based on the user
+configured regulatory domain.
+Depending on the EEPROM data this can cause the tx power to become too
+limited, if the original regdomain CTLs impose lowr limits than the CTLs
+of the user configured regdomain.
+
+To fix this issue, set the initial channel limits without any CTL
+restrictions and only apply the CTL at run time when setting the channel
+and the real tx power.

+Subject: [PATCH v4 2/8] mac80211: ath9k: set default state for platform LEDs
+
+Support default state for platform LEDs connected to ath9k device.
+Now LEDs are correctly set on or off at ath9k module initialization.
+Very useful if power LED is connected to wireless chip.

+Subject: [PATCH] ath10k: Don't initialize devices asynchronously
+
+OpenWrt requires all PHYs to be initialized to create the configuration files
+during bootup. ath10k violates this because it delays the creation of the PHY
+to a not well defined point in the future.
+
+Forcing the work to be done immediately works around this problem but may also
+delay the boot when firmware images cannot be found.

+
+current handling of peer_bw_rxnss_override parameter is based on guessing the VHT160/8080 capability by rx rate. this is wrong and may lead
+to a non initialized peer_bw_rxnss_override parameter which is required since VHT160 operation mode only supports 2x2 chainmasks in addition the original code
+initialized the parameter with wrong masked values.
+This patch uses the peer phymode and peer nss information for correct initialisation of the peer_bw_rxnss_override parameter.
+if this peer information is not available, we initialize the parameter by minimum nss which is suggested by QCA as temporary workaround according
+to the QCA sourcecodes.

+v2: remove debug messages
+v3: apply some cosmetics, update documentation
+v4: fix compile warning and truncate nss to maximum of 2x2 since current chipsets only support 2x2 at vht160
+v5: handle maximum nss for chipsets supportig vht160 with 1x1 only
+v7: use more simple code variant and take care about hw/sw chainmask configuration
+v8: fix some code style issues

+starting with firmware 10.4.3.4.x series QCA changed the handling of the channel property band_center_freq1 and band_center_freq2 in vht160 operation mode
+likelly for backward compatiblity with vht80 only capable clients.
+this patch adjusts the handling to get vht160 to work again with official qca firmwares newer than 3.3
+consider that this patch will not work with older firmwares anymore. to avoid undefined behaviour this we disable vht160 capability for outdated firmwares

+Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
+
+Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
+the RX and TX path. These filtered channel can in theory still be used by
+the hardware but the signal strength is reduced so much that it makes no
+sense.
+
+There is already a DT property to limit the available channels but ath10k
+has to manually call this functionality to limit the currrently set wiphy
+channels further.

+Subject: [PATCH] mac80211: add NEED_ALIGNED4_SKBS hw flag
+
+HW/driver should set NEED_ALIGNED4_SKBS flag in case
+require aligned skbs to four-byte boundaries.
+This affect only TX direction.
+
+Padding is added after ieee80211_hdr, before IV/LLC.
+
+Before we have to do memmove(hdrlen) twice in the
+dirver. Once before we pass this to HW and next
+in tx completion (to be sure monitor will report
+this tx frame correctly).
+
+With this patch we can skip this memmove() and save CPU.
+
+Currently this was tested with ath9k, both hw/sw crypt for
+wep/tkip/ccmp.

+Subject: [PATCH] mac80211: minstrel: reduce minstrel_mcs_groups size
+
+By storing a shift value for all duration values of a group, we can
+reduce precision by a neglegible amount to make it fit into a u16 value.
+This improves cache footprint and reduces size:
+
+Before:
+ text data bss dec hex filename
+ 10024 116 0 10140 279c rc80211_minstrel_ht.o
+
+After:
+ text data bss dec hex filename
+ 9368 116 0 9484 250c rc80211_minstrel_ht.o

+ in HT mode
+
+Long/short preamble selection cannot be sampled separately, since it
+depends on the BSS state. Because of that, sampling attempts to
+currently not used preamble modes are not counted in the statistics,
+which leads to CCK rates being sampled too often.
+
+Fix statistics accounting for long/short preamble by increasing the
+index where necessary.
+Fix excessive CCK rate sampling by dropping unsupported sample attempts.

+Subject: [PATCH] mac80211: fix memory accounting with A-MSDU aggregation
+
+fq uses skb->truesize for memory usage tracking. Increments/decrements
+are done on enqueue/dequeue.
+When A-MSDU aggregation is performed on tx side, the packet is
+aggregated with the last packet in the queue belonging to the same flow.
+There are multiple bugs here:
+- The truesize field of the aggregated packet isn't updated, so memory
+usage is underestimated
+- fq->memory_usage isn't adjusted.
+
+Because of the combination of both bugs, this only causes tx issues in
+rare cases, mainly when the A-MSDU head needs to be reallocated.
+
+Fix this by adjusting both truesize of the A-MSDU head and adding the
+truesize delta to fq->memory_usage.

+Subject: [PATCH v2] cfg80211: initialize sinfo in cfg80211_get_station
+
+Most of the implementations behind cfg80211_get_station will not initialize
+sinfo to zero before manipulating it. For example, the member "filled",
+which indicates the filled in parts of this struct, is often only modified
+by enabling certain bits in the bitfield while keeping the remaining bits
+in their original state. A caller without a preinitialized sinfo.filled can
+then no longer decide which parts of sinfo were filled in by
+cfg80211_get_station (or actually the underlying implementations).
+
+cfg80211_get_station must therefore take care that sinfo is initialized to
+zero. Otherwise, the caller may tries to read information which was not
+filled in and which must therefore also be considered uninitialized. In
+batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
+may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
+switch to non-optimal neighbors for certain destinations.
+
