Subject: [PATCH] ath: regd: add extra coutry codes
This patch adds several country codes to the regd.h and regd_common.h
files in order to support devices whose country codes are not present in
the original list. Without this patch, all devices whose manufacturer
programmed any of these code in their EEPROM will not work.

Subject: [PATCH] ath10k: add support for configuring management packet rate
By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.
This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

Subject: [PATCH] ath10k: fix possible out of bound access of ath10k_rates array
While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
from the passed bitrate, there is a chance of out of bound array access
when wrong bitrate is passed. This is fixed by comparing the bitrates
within the correct size of the ath10k_rates array.
Fixes commit f279294e9ee2 ("ath10k: add support for configuring management
packet rate"). Also correction made to some indents used in the above commit.

Subject: [PATCH wireless-drivers] brcmfmac: fix roamoff=1 modparam
When the update_connect_param callback is set, nl80211 expects the flag
WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is
only set when modparam roamoff=0, while the callback is set
unconditionally. Since commit 7f9a3e150ec7 this causes a warning in
wiphy_register, which breaks brcmfmac.
Disable the update_connect_param callback when roamoff=0 to fix this.

MIME-Version: 1.0

Previous commit /adding/ support for 160 MHz chanspecs was incomplete.
It didn't set bandwidth info and didn't extract control channel info. As
the result it was also using uninitialized "sb" var.
This change has been tested for two chanspecs found to be reported by
some devices/firmwares:
1) 60/160 (0xee32)
Before: chnum:50 control_ch_num:36
After: chnum:50 control_ch_num:60
2) 120/160 (0xed72)
Before: chnum:114 control_ch_num:100
After: chnum:114 control_ch_num:120

The newest firmwares provide STA info using v7 of the struct. As v7
isn't backward compatible, a union is needed.
Even though brcmfmac does not use any of the new info it's important to
provide the proper struct buffer. Without this change new firmwares will
fallback to the very limited v3 instead of something in between such as
v4.

Subject: [PATCH] brcmfmac: Call brcmf_dmi_probe before brcmf_of_probe
ARM systems with UEFI may have both devicetree (of) and DMI data in this
case we end up setting brcmf_mp_device.board_type twice.
In this case we should prefer the devicetree data, because:
1) The devicerree data is more reliable
2) Some ARM systems (e.g. the Raspberry Pi 3 models) support both UEFI and
classic uboot booting, the devicetree data is always there, so using it
makes sure we ask for the same nvram file independent of how we booted.
This commit moves the brcmf_dmi_probe call to before the brcmf_of_probe
call, so that the latter can override the value of the first if both are
set.

The credit numbers are static and tunable per chip in firmware side.
However the credit number may be changed that is based on packet pool
length and will send BRCMF_E_FIFO_CREDIT_MAP event to notify host driver
updates the credit numbers during interface up.
The purpose of this patch is making host driver has ability of updating
the credit numbers when receiving the BRCMF_E_FIFO_CREDIT_MAP event.

Subject: [PATCH] brcmfmac: enable frameburst mode in default firmware setting
The frameburst feature can enable per-packet framebursting in firmware
side and get higher TX throughput in High Throughput(HT) mode. To enhance
TX throughput, we enable frameburst mode in default firmware setting.

Subject: [PATCH] brcmfmac: allow GCI core enumuration
GCI core is needed for ULP operation. Allow GCI core enumuration with
below changes:
- Allow GCI to be added to core list even when it doesn't have a wrapper.
- Allow 8K address space size.
- Don't overwrite the address value when an additional size descriptor
is in place.

Subject: [PATCH] brcmfmac: update 43012 F2 watermark setting to fix DMA Error
during UDP RX Traffic
The number of words that the read FIFO has to contain except
the end of frame before sends data back to the host.
Max watermark = (512B - 2* (BurstLength))/4 =
(512 - 128)/4 = 384/4 = 0x60
so if burst length (i.e. BurstLength = 64) is increased,
watermark has to be reduced. This is the optimal setting for this chip.

Subject: [PATCH] brcmfmac: disable command decode in sdio_aos
AOS is a part of the SDIOD core that becomes active when the rest of
SDIOD is sleeping to keep SDIO bus alive responding to reduced set of
commands.
Transaction between AOS and SDIOD is not protected, and if cmd 52 is
received in AOS and in the middle of response state changed from AOS to
SDIOD, response is corrupted and it causes to SDIO Host controller to
hang.
Command decode for below chips are disabled in this commit:

Subject: [PATCH] brcmfmac: fix false-positive -Wmaybe-unintialized warning
When CONFIG_NO_AUTO_INLINE is set, we get a false-postive warning
for the brcmf_fw_request_nvram_done() function, after gcc figures
out that brcmf_fw_nvram_from_efi() might not set the 'data_len'
variable, but fails to notice that it always returns NULL:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c: In function 'brcmf_fw_request_nvram_done':
drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c:560:11: error: 'data_len' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Mark it 'inline' to force gcc to understand this.

Since commit 1204aa17f3b4 ("brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag")
the Raspberry Pi 3 A+ (BCM43455) isn't able to operate in AP mode with
hostapd (device_ap_sme=1 use_monitor=0):

Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for PoV TAB-P1006W-232
tablet
The Point of View TAB-P1006W-232 tablet contains quite generic names in
the sys_vendor and product_name DMI strings, without this patch brcmfmac
will try to load: brcmfmac43340-sdio.Insyde-BayTrail.txt as nvram file
which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file
name is used on the PoV TAB-P1006W-232 tablet.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).
This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.
All bus files should follow & get updated similarly (soon).

Subject: [PATCH] brcmfmac: support monitor frames with the hardware/ucode
header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far there were two monitor frame formats:
1) 802.11 frames (with frame (sub)type & all addresses)
2) 802.11 frames with the radiotap header
Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in
discovering a new format being used. It seems (almost?) identical to the
one known from ucode used in SoftMAC devices which is most likely the
same codebase anyway.
While new firmwares will /announce/ radiotap header support using the
"rtap" fw capability string it seems no string was added for the new
ucode header format.
All above means that:
1) We need new format support when dealing with a received frame
2) A new feature bit & mapping quirks have to be added manually
As for now only an empty radiotap is being created. Adding support for
extracting some info (band, channel, signal, etc.) is planned for the
future.

For USB there is no separate channel being used to pass events
from firmware to the host driver and as such are passed over the
data path. In order to detect mock event messages an additional
check is needed on event subtype. This check is added conditionally
using unlikely() keyword.

Subject: [PATCH] brcmfmac: create debugfs files for bus-specific layer
Since we moved the drivers debugfs directory under ieee80211 debugfs the
debugfs entries need to be added after wiphy_register() has been called.
For most part that has been done accordingly, but for the debugfs entries
added by SDIO it was not and failed silently. This patch fixes that by
adding a bus-layer callback for it.
Fixes: 856d5a011c86 ("brcmfmac: allocate struct brcmf_pub instance using wiphy_new()")

Subject: [PATCH] brcmfmac: disable MBSS feature for bcm4330 device
The MBSS feature was already disabled for bcm43362 as it resulted in a
beacon with BRCM_TEST_SSID regardless user configuration in hostapd. Now
the same has been reported for bcm4330 so disable the feature for this
device as well.

Subject: [PATCH] brcmfmac: use chipname in brcmf_fw_alloc_request() for error
path as well
The local variable chipname is string representation of chip id and revision
which is printed in the good flow of brcmf_fw_alloc_request(). Also use it
for the error path, ie. for unknown/unsupported devices.

Subject: [PATCH] brcmfmac: add basic validation of shared RAM address
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
While experimenting with firmware loading I ended up in a state of
firmware reporting shared RAM address 0x04000001. It was causing:
[ 94.448015] Unable to handle kernel paging request at virtual address cd680001
due to reading out of the mapped memory.
This patch adds some basic validation to avoid kernel crashes due to the
unexpected firmware behavior.

Subject: [PATCH 01/28] rt2x00: use simple_read_from_buffer()
The problem with this copy_to_user() calls is that they don't ensure
that "size" is less than the "length" which the user provided.
Obviously, this is debugfs and "size" is normally going to be very small
so it probably doesn't matter, but this is the correct thing to do.

Content-Transfer-Encoding: 8bit
Current implementation of RT6352 support provides too high tx power
at least on iPA/eLNA devices. Reduce amplification of variable gain
amplifier by 6dB to match board target power of 17dBm.
Transmited signal strength with this patch is similar to that of
stock firmware or pandorabox firmware. Throughput measured with iperf
improves. Device tested: Xiaomi Miwifi Mini.

Subject: [PATCH 13/28] rt2x00: Work around a firmware bug with shared keys
Apparently the rt2x61 firmware fails temporarily to decode
broadcast packets if the shared keys are not assigned
in the "correct" sequence. At the same time unicast
packets work fine, since they are encrypted with the
pairwise key.
At least with WPA2 CCMP mode the shared keys are
set in the following sequence: keyidx=1, 2, 1, 2.
After a while only keyidx 2 gets decrypted, and
keyidx 1 is ignored, probably because there is never
a keyidx 3.
Symptoms are arping -b works for 10 minutes, since
keyidx=2 is used for broadcast, and then it stops
working for 10 minutes, because keyidx=1 is used.
That failure mode repeats forever.
Note, the firmware does not even know which keyidx
corresponds to which hw_key_idx so the firmware is
trying to be smarter than the driver, which is bound
to fail.
As workaround the function rt61pci_config_shared_key
requests software decryption of the shared keys,
by returning EOPNOTSUPP. However, pairwise keys are
still handled by hardware which works just fine.

Subject: [PATCH 20/28] rt2x00: do not print error when queue is full
For unknown reasons printk() on some context can cause CPU hung on
embedded MT7620 AP/router MIPS platforms. What can result on wifi
disconnects.
This patch move queue full messages to debug level what is consistent
with other mac80211 drivers which drop packet silently if tx queue is
full. This make MT7620 OpenWRT routers more stable, what was reported
by various users.

Subject: [PATCH 25/28] rt2800mmio: use timer and work for handling tx statuses
timeouts
Sometimes we can get into situation when there are pending statuses,
but we do not get INT_SOURCE_CSR_TX_FIFO_STATUS. Handle this situation
by arming timeout timer and read statuses (it will fix case when
we just do not have irq) and queue work to handle case we missed
statues from hardware FIFO.
