ieee80211_find_sta_by_ifaddr() must be called under the RCU lock and the resulting pointer is only valid under RCU lock as well. Fix ath10k_wmi_tlv_op_pull_peer_stats_info() to hold RCU lock before it calls ieee80211_find_sta_by_ifaddr() and release it when the resulting pointer is no longer needed. This problem was found while reviewing code to debug RCU warn from ath10k_wmi_tlv_parse_peer_stats_info().

Based on the comment block in this function and the FIXME for this, peer being present for the offchannel tx is unlikely. Peer is deleted once tx is complete. Change peer present msg to a warn to detect this condition. Signed-off-by:

FW reports Tx/Rx extended MCS 12.1 to driver as "26". Driver will convert this into base MCS 7 + EXTENDED_SC_DMG flag so kernel can do the correct phy rate conversion. Also add log prints to print "12.1" instead of "26" for extended MCS. Signed-off-by:

Multiple structures in the carl9170 driver have alignment impossible alignment constraints that gcc warns about when building with 'make W=1': drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned] drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned] In the carl9170_cmd structure, multiple members that have an explicit alignment requirement of four bytes are added into a union with explicit byte alignment, but this in turn is part of a structure that also has four-byte alignment. In the wlan.h header, multiple structures contain a ieee80211_hdr member that is required to be two-byte aligned to avoid alignmnet faults when processing network headers, but all members are forced to be byte-aligned using the __packed tag at the end of the struct definition. In both cases, leaving out the packing does not change the internal layout of the structure but changes the alignment constraint of the structure itself. Change all affected structures to only apply packing where it does not violate the alignment requirement of the contained structure. Signed-off-by:

Tx descriptor search index field should be updated with hw peer id and not by AST Hash as per the HW/FW recommendation. Incorrect search index causes throughput degradation in all scenario for all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms. Also no need of these configuration for non station type. seen 10% throughput increase in WDS traffic with this change.

When a network is moved or reconfigured on the different channel, there can be multiple BSSes with the same BSSID and SSID in scan result before the old one expires. Then, it can cause cfg80211_connect_result to map current_bss to a bss with the wrong channel. Let mwifiex_cfg80211_assoc return the selected BSS and then the caller can report it cfg80211_connect_bss. Signed-off-by:

The Voyo winpad A15 tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..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 Voyo winpad A15 tablet. While preparing a matching linux-firmware update I noticed that the nvram is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI quirk entry simply points to the already existing Prowise-PT301 nvram file.

In commit d3ccc14d most of the tasklets in this driver was updated to the new API. However for the rx_work_tasklet only the type of the callback was changed from void _rtl_rx_work(unsigned long data) to void _rtl_rx_work(struct tasklet_struct *t). The initialization of rx_work_tasklet was still open-coded and the function pointer just cast into the old type, and hence nothing sets rx_work_tasklet.use_callback = true and the callback was still called as t->func(t->data); with uninitialized/zero t->data. Commit 6b8c7574 changed the casting of _rtl_rx_work a bit and initialized t->data to a pointer to the tasklet cast to an unsigned long. This way calling t->func(t->data) might actually work through all the casting, but it still doesn't update the code to use the new tasklet API. Let's use the new tasklet_setup to initialize rx_work_tasklet properly and set rx_work_tasklet.use_callback = true so that the callback is called as t->callback(t); without all the casting.

Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-02-05 This series contains updates to ice driver only. Jake adds adds reporting of timeout length during devlink flash and implements support to report devlink info regarding the version of firmware that is stored (downloaded) to the device, but is not yet active. ice_devlink_info_get will report "stored" versions when there is no pending flash update. Version info includes the UNDI Option ROM, the Netlist module, and the fw.bundle_id. Gustavo A. R. Silva replaces a one-element array to flexible-array member. Bruce utilizes flex_array_size() helper and removes dead code on a check for a condition that can't occur. v2: * removed security revision implementation, and re-ordered patches to account for this removal * squashed patches implementing ice_read_flash_module to avoid patches refactoring the implementation of a previous patch in the series * modify ice_devlink_info_get to always report "stored" versions instead of only reporting them when a pending flash update is ready. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: remove dead code ice: use flex_array_size where possible ice: Replace one-element array with flexible-array member ice: display stored UNDI firmware version via devlink info ice: display stored netlist versions via devlink info ice: display some stored NVM versions via devlink info ice: introduce function for reading from flash modules ice: cache NVM module bank information ice: introduce context struct for info report ice: create flash_info structure and separate NVM version ice: report timeout length for erasing during devlink flash ==================== Link: https://lore.kernel.org/r/20210206044101.636242-1-anthony.l.nguyen@intel.comSigned-off-by:

The "dev_has_header" function, recently added in commit d5496990 ("net/packet: fix packet receive on L3 devices without visible hard header"), is more accurate as criteria for determining whether a device exposes the LL header to upper layers, because in addition to dev->header_ops, it also checks for dev->header_ops->create. When transmitting an skb on a device, dev_hard_header can be called to generate an LL header. dev_hard_header will only generate a header if dev->header_ops->create is present. Signed-off-by:

Alex Elder says: ==================== net: ipa: a mix of small improvements Version 2 of this series restructures a couple of the changed functions (in patches 1 and 2) to avoid blocks of indented code by returning early when possible, as suggested by Jakub. The description of the first patch was changed as a result, to better reflect what the updated patch does. It also fixes one spot I identified when updating the code, where gsi_channel_stop() was doing the wrong thing on error. The original description for this series is below. This series contains a sort of unrelated set of code cleanups. The first two are things I wanted to do in a series that updated some NAPI code recently. I didn't want to change things in a way that affected existing testing so I set these aside for later (i.e., now). The third makes a change to event ring handling that's similar to what was done a while back for channels. There's little benefit to cacheing the current state of an event ring, so with this we'll just fetch the state from hardware whenever we need it. The fourth patch removes the definitions of two unused symbols. The fifth replaces a count that is always 0 or 1 with a Boolean. The sixth removes a build-time validation check that doesn't really provide benefit. And the last one fixes a problem (in two spots) that could cause a build-time check to fail "bogusly". ==================== Link: https://lore.kernel.org/r/20210205221100.1738-1-elder@linaro.orgSigned-off-by:
