2023-10-23wifi: iwlwifi: mvm: update station's MFP flag after associationAvraham Stern1-0/+6
The management frames protection flag is always set when the station is not yet authorized. However, it was not cleared after association even if the association did not use MFP. As a result, all public action frames are not parsed by fw (which will cause FTM to fail, for example). Update the station MFP flag after the station is authorized.

2023-10-19net: introduce napi_is_scheduled helperChristian Marangi1-1/+1
We currently have napi_if_scheduled_mark_missed that can be used to check if napi is scheduled but that does more thing than simply checking it and return a bool. Some driver already implement custom function to check if napi is scheduled. Drop these custom function and introduce napi_is_scheduled that simply check if napi is scheduled atomically. Update any driver and code that implement a similar check and instead use this new helper. Signed-off-by: Christian Marangi <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>

DCFO tracking compensate the CFO (carrier frequency offset) by digital hardware that provides fine CFO estimation.

2023-10-18wifi: ath5k: replace deprecated strncpy with strscpyJustin Stitt1-2/+1
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect led->name to be NUL-terminated based on the presence of a manual NUL-byte assignment. This NUL-byte assignment was added in Commit daf9669bea30aa22 ("ath5k: ensure led name is null terminated"). If strscpy() had existed and had been used back when this code was written then potential bugs and the need to manually NUL-terminate could have been avoided. Since we now have the technology, let's use it :) Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. If NUL-padding is required let's opt for strscpy_pad().

2023-10-12wifi: ath11k: ath11k_debugfs_register(): fix format-truncation warningKalle Valo1-2/+2
In v6.6-rc4 with GCC 13.2 I see a new warning: drivers/net/wireless/ath/ath11k/debugfs.c: In function 'ath11k_debugfs_register': drivers/net/wireless/ath/ath11k/debugfs.c:1597:51: error: '%d' directive output may be truncated writing between 1 and 3 bytes into a region of size 2 [-Werror=format-truncation=] drivers/net/wireless/ath/ath11k/debugfs.c:1597:48: note: directive argument in the range [0, 255] drivers/net/wireless/ath/ath11k/debugfs.c:1597:9: note: 'snprintf' output between 5 and 7 bytes into a destination of size 5 Increase the size of pdev_name to 10 bytes to make sure there's enough room for the string. Also change the format to '%u' as ar->pdev_idx is u8. Compile tested only. Signed-off-by: Kalle Valo <[email protected]> Link: https://lore.kernel.org/r/[email protected]
2023-10-12wifi: rtw89: coex: add annotation __counted_by() to struct ↵Ping-Ke Shih1-6/+5
rtw89_btc_btf_set_mon_reg Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). Use struct_size() and flex_array_size() helpers to calculate proper sizes for allocation and memcpy(). Don't change logic at all, and result is identical as before.

Since we have TX rate from RA report of C2H event and RX rate from RX descriptor, show them in debugfs like TX rate [1]: EHT 2SS MCS-7 GI:3.2 BW:80 (hw_rate=0x427) RX rate [1]: EHT 2SS MCS-7 GI:3.2 BW:80 (hw_rate=0x427) Signed-off-by: Ping-Ke Shih <[email protected]> Signed-off-by: Kalle Valo <[email protected]> Link: https://lore.kernel.org/r/[email protected]

RA (rate adaptive) C2H report is to reflect current TX rate firmware is using. Parse C2H event encoded in EHT mode, and then user space and debugfs can use the information to know TX rate.

2023-10-12wifi: rtw89: parse EHT information from RX descriptor and PPDU status packetPing-Ke Shih1-15/+44
There are two kinds of RX packets -- normal and its PPDU status packet. Both have RX descriptor containing some information such as rate, GI and bandwidth, and we use these information to find the relationship between two kinds of packets. Then, we can get more information like RSSI and EVM from PPDU status packet.
