wifi: cfg80211: fix the order of arguments for trace events of the tx_rx_evt class

2024-06-12T09:11:22+00:00

[ Upstream commit 9ef369973cd2c97cce3388d2c0c7e3c056656e8a ] The declarations of the tx_rx_evt class and the rdev_set_antenna event use the wrong order of arguments in the TP_ARGS macro. Fix the order of arguments in the TP_ARGS macro. Found by Linux Verification Center (linuxtesting.org) with SVACE.

wifi: cfg80211/nl80211: Add support to indicate STA MLD setup links removal

2023-06-19T10:08:40+00:00

STA MLD setup links may get removed if AP MLD remove the corresponding affiliated APs with Multi-Link reconfiguration as described in P802.11be_D3.0, section 35.3.6.2.2 Removing affiliated APs. Currently, there is no support to notify such operation to cfg80211 and userspace. Add support for the drivers to indicate STA MLD setup links removal to cfg80211 and notify the same to userspace. Upon receiving such indication from the driver, clear the MLO links information of the removed links in the WDEV.

wifi: cfg80211: add inform_bss op to update BSS

wifi: cfg80211: make TDLS management link-aware

2023-06-19T10:05:27+00:00

For multi-link operation(MLO) TDLS management frames need to be transmitted on a specific link. The TDLS setup request will add BSSID along with peer address and userspace will pass the link-id based on BSSID value to the driver(or mac80211).

wifi: cfg80211: replace strlcpy() with strscpy()

2023-06-14T10:32:19+00:00

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since WIPHY_ASSIGN is only used by TRACE macros and the return values are ignored.

wifi: nl80211: add a command to enable/disable HW timestamping

2023-03-07T09:52:00+00:00

Add a command to enable and disable HW timestamping of TM and FTM frames. HW timestamping can be enabled for a specific mac address or for all addresses. The low level driver will indicate how many peers HW timestamping can be enabled concurrently, and this information will be passed to userspace.

Add support to offload OWE processing to user space for MLD AP when driver's SME in use. Add new parameters in struct cfg80211_update_owe_info to provide below information in cfg80211_update_owe_info_event() call: - MLO link ID of the AP, with which station requested (re)association. This is applicable for both MLO and non-MLO station connections when the AP affiliated with an MLD. - Station's MLD address if the connection is MLO capable.
