2023-05-17wifi: rtw89: 8851b: add BT coexistence support functionPing-Ke Shih
Add 8851B specific parameters of BT coexistence. Since 8851B has special two antenna hardware module with antenna diversity, BT coexistence needs to recognize this, so add some fields to store these information for further use.

2023-05-17wifi: b43: fix incorrect __packed annotationArnd Bergmann
clang warns about an unpacked structure inside of a packed one: drivers/net/wireless/broadcom/b43/b43.h:654:4: error: field data within 'struct b43_iv' is less aligned than 'union (unnamed union at /home/arnd/arm-soc/drivers/net/wireless/broadcom/b43/b43.h:651:2)' and is usually due to 'struct b43_iv' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access] The problem here is that the anonymous union has the default alignment from its members, apparently because the original author mixed up the placement of the __packed attribute by placing it next to the struct member rather than the union definition. As the struct itself is also marked as __packed, there is no need to mark its members, so just move the annotation to the inner type instead. As Michael noted, the same problem is present in b43legacy, so change both at the same time.

2023-05-17wifi: rtw88: sdio: Always use two consecutive bytes for word operationsMartin Blumenstingl
The Allwinner sunxi-mmc controller cannot handle word (16 bit) transfers. So and sdio_{read,write}w fails with messages like the following example using an RTL8822BS (but the same problems were also observed with RTL8822CS and RTL8723DS chips): rtw_8822bs mmc1:0001:1: Firmware version 27.2.0, H2C version 13 sunxi-mmc 4021000.mmc: unaligned scatterlist: os f80 length 2 sunxi-mmc 4021000.mmc: map DMA failed rtw_8822bs mmc1:0001:1: sdio read16 failed (0x10230): -22 Use two consecutive single byte accesses for word operations instead. It turns out that upon closer inspection this is also what the vendor driver does, even though it does have support for sdio_{read,write}w. So we can conclude that the rtw88 chips do support word access but only on SDIO controllers that also support it. Since there's no way to detect if the controller supports word access or not the rtw88 sdio driver switches to the easiest approach: avoiding word access.

2023-05-16wifi: iwlwifi: mvm: Add locking to the rate read flowAriel Malamud
The rs_drv_get_rate flow reads the lq_sta to return the optimal rate for tx frames. This read flow is not protected thereby leaving a small window, a few instructions wide, open to contention by an asynchronous rate update. Indeed this race condition was hit and the update occurred in the middle of the read. Fix this by locking the lq_sta struct during read.

2023-05-16wifi: iwlwifi: mvm: don't trust firmware n_channelsJohannes Berg
If the firmware sends us a corrupted MCC response with n_channels much larger than the command response can be, we might copy far too much (uninitialized) memory and even crash if the n_channels is large enough to make it run out of the one page allocated for the FW response.

2023-05-16wifi: iwlwifi: fw: fix DBGI dumpJohannes Berg
The DBGI dump is (unsurprisingly) of type DBGI, not SRAM. This leads to bad register accesses because the union is built differently, there's no allocation ID, and thus the allocation ID ends up being 0x8000. Note that this was already wrong for DRAM vs. SMEM since they use different parts of the union, but the allocation ID is at the same place, so it worked. Fix all of this but set the allocation ID in a way that the offset calculation ends up without any offset. Fixes: 34bc27783a31 ("iwlwifi: yoyo: fix DBGI_SRAM ini dump header.")

Newer FW re-design SER (syetem error recovery) L1 (level 1) flow. New L1 flow will expect two extra states before original L1 flow. * Before: fw --- M1 --> driver fw <-- M2 --- driver fw --- M3 --> driver fw <-- M4 --- driver fw --- M5 --> driver * After: fw --- pre-M0 --> driver fw <-- post-M0 --- driver fw --- M1 --> driver fw <-- M2 --- driver fw --- M3 --> driver fw <-- M4 --- driver fw --- M5 --> driver Then before M1, FW gets one more interval to deal with things that FW should have handled well. To consider backward/forward compatibility, FW and driver won't change flow from M1 to M5. (only except that halt trigger control will change a little bit.) So, there will be two differnt starting points of SER L1. * old FW: SER L1 starts from M1 * new FW: SER L1 starts from pre-M0 Then, driver adds the new SER L1 entry and also keep the original one instead of changing it.
