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

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.

Subject: [PATCH] ath10k: fix build errors with !CONFIG_PM
Build errors have been reported with CONFIG_PM=n:
drivers/net/wireless/ath/ath10k/pci.c:3416:8: error: implicit
declaration of function 'ath10k_pci_suspend'
[-Werror=implicit-function-declaration]
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

If there are multiple mesh stations with the same MAC address,
they will both get confused and start throwing warnings.
Obviously in this case nothing can actually work anyway, so just
drop frames that look like they're from ourselves early on.

Subject: [PATCH] brcmfmac: handle FWHALT mailbox indication
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: get rid of brcmf_cfg80211_escan() function
The function brcmf_cfg80211_escan() is only called by brcmf_cfg80211_scan()
so there is no reason to split in two function especially since the latter
does not do an awful lot.

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.

Subject: [PATCH] brcmfmac: fix CLM load error for legacy chips when user
helper is enabled
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 2/2] ath10k: move spectral scan support under a separate
config symbol
At the moment, spectral scan support, and with it RELAY, is always enabled
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
RELAY in ath10k, and it unconditionally reserves a relay channel.
Having debugfs support in ath10k is often useful even on very small
embedded routers, where we'd rather like to avoid the code size and RAM
usage of the relay support. While ath10k-based devices usually have more
resources than ath9k-based ones, it makes sense to keep the configuration
symmetric to ath9k, so the same base kernel without RELAY can be used for
both ath9k and ath10k hardware.

Subject: [PATCH] brcmfmac: Register sizes on hardware are not dependent on
compiler types
The 4 IO functions in this patch are incorrect as they use compiler types
to determine how many bytes to send to the hardware.

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.

Subject: [PATCH] brcmfmac: Clean up brcmf_sdiod_set_sbaddr_window()
This function sets the address of the IO window used for
SDIO accesses onto the backplane of the chip.
It currently uses 3 separate masks despite the full mask being
defined in the code already. Remove the separate masks and clean up.

Subject: [PATCH] brcmfmac: Remove brcmf_sdiod_request_data()
This function is obfuscating how IO works on this chip. Remove it
and push its logic into brcmf_sdiod_reg_{read,write}().
Handling of -ENOMEDIUM is altered, but as that's pretty much broken anyway
we can ignore that.

Subject: [PATCH] brcmfmac: Fix asymmetric IO functions.
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.

From 71bd508d7ded8c504ef05d1b4befecfe25e54cb1 Mon Sep 17 00:00:00 2001
From: Ian Molton <ian@mnementh.co.uk>
Date: Fri, 8 Dec 2017 13:10:29 +0100
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: remove unnecessary call to
brcmf_sdiod_set_backplane_window()
All functions that might require the window address changing call
brcmf_sdiod_set_backplane_window() prior to access. Thus resetting
the window is not required.

Subject: [PATCH] brcmfmac: Remove repeated calls to brcmf_chip_get_core()
There is no need to repeatdly call brcmf_chip_get_core(), which
traverses a list of cores every time its called (including during
register access code!).
Call it once, and store a pointer to the core structure. The existing
code does nto keep track of users of the cores anyway, and even so, this
will allow for easier refcounting in future.

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.

The IO functions operate within the Chipcommon IO window. Explicitly
set this, rather than relying on the last initialisation IO access to
leave it set to the right value by chance.

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.

Subject: [PATCH] mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple
of 4
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
template memory on the chip.
Misaligned 32-bit accesses cause CPU exceptions on MIPS and should be
avoided.

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: add possibility to obtain firmware error
The feature module needs to evaluate the actual firmware error return
upon a control command. This adds a flag to struct brcmf_if that the
caller can set. This flag is checked to determine the error code that
needs to be returned.

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.

brcmf_cfg80211_reg_notifier() expect valid ISO3166 codes in the complete

No longer needed to call this in bus layer so make it static and call
it in the last phase of brcmf_attach() instead.

Subject: [PATCH] brcmfmac: do not convert linux error to firmware error string
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
print only the numeric error code and be done with it.

Subject: [PATCH] brcmfmac: use brcmf_chip_name() to store name in revinfo
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.

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

Subject: [PATCH] brcmfmac: use wiphy debugfs dir entry
The driver used to create a brcmfmac dir entry at the top level
debugfs mount point. This moves the debugfs entries into the
wiphy debugfs dir entry.

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.

Subject: [PATCH] brcmfmac: reports boottime_ns while informing bss
Provides a timestamp in bss information so user space can see when the
bss info was updated. Since tsf is not available from the dongle events
boottime is reported instead.

Subject: [PATCH] brcmfmac: use nl80211_band directly to get ieee80211 channel
The enum nl80211_band used to retrieve wiphy->bands is the same as
wiphy->bands->band which is checked by wiphy_register(). So it can be used
directly as parameter of ieee80211_channel_to_frequency().
