2023-08-24wifi: mac80211: Do not include crypto/algapi.hHerbert Xu
The header file crypto/algapi.h is for internal use only. Use the header file crypto/utils.h instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Link: https://lore.kernel.org/r/E1qYlA0-006vFr-Ts@formenos.hmeau.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2023-08-23wifi: wilc1000: Remove unused declarationsYue Haibing
Commit 8399918f3056 ("staging: wilc1000: use RCU list to maintain vif interfaces list") removed wilc_get_interface() but not its declaration. Commit 9bc061e88054 ("staging: wilc1000: added support to dynamically add/remove interfaces") declared but never implemented wilc_cfg_alloc() and wilc_netdev_interface().

2023-08-23wifi: mwifiex: avoid possible NULL skb pointer dereferenceDmitry Antipov
In 'mwifiex_handle_uap_rx_forward()', always check the value returned by 'skb_copy()' to avoid potential NULL pointer dereference in 'mwifiex_uap_queue_bridged_pkt()', and drop original skb in case of copying failure. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2023-08-23wifi: rt2x00: limit MT7620 TX power based on eeprom calibrationShiji Yang
In the vendor driver, the current channel power is queried from EEPROM_TXPOWER_BG1 and EEPROM_TXPOWER_BG2. And then the mixed value will be written into the low half-word of the TX_ALC_CFG_0 register. The high half-word of the TX_ALC_CFG_0 is a fixed value 0x2f2f. We can't get the accurate TX power. Based on my tests and the new MediaTek mt76 driver source code, the real TX power is approximately equal to channel_power + (max) rate_power. Usually max rate_power is the gain of the OFDM 6M rate, which can be readed from the offset EEPROM_TXPOWER_BYRATE +1. Based on these eeprom values, this patch adds basic TX power control for the MT7620 and limits its maximum TX power. This can avoid the link speed decrease caused by chip overheating. rt2800_config_alc() function has also been renamed to rt2800_config_alc_rt6352() because it's only used by RT6352 (MT7620). Notice: It's still need some work to sync the max channel power to the user interface. This part is missing from the rt2x00 driver framework. If we set the power exceed the calibration value, it won't take effect.

2023-08-22mac80211: make ieee80211_tx_info padding explicitArnd Bergmann
While looking at a bug, I got rather confused by the layout of the 'status' field in ieee80211_tx_info. Apparently, the intention is that status_driver_data[] is used for driver specific data, and fills up the size of the union to 40 bytes, just like the other ones. This is indeed what actually happens, but only because of the combination of two mistakes: - "void *status_driver_data[18 / sizeof(void *)];" is intended to be 18 bytes long but is actually two bytes shorter because of rounding-down in the division, to a multiple of the pointer size (4 bytes or 8 bytes). - The other fields combined are intended to be 22 bytes long, but are actually 24 bytes because of padding in front of the unaligned tx_time member, and in front of the pointer array. The two mistakes cancel out. so the size ends up fine, but it seems more helpful to make this explicit, by having a multiple of 8 bytes in the size calculation and explicitly describing the padding.
