treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

wifi: mac80211: add initial UHR support

wifi: mac80211: make monitor link info check more specific

2025-11-11T10:05:19+00:00

Verify that only one of the permitted change flags is set when changing the link of a monitor interface. Before the WARN_ON_ONCE would accept anything if mu_mimo_owner was set. Also, split out the mu_mimo_owner flag and enable it for all interface types. The option is set during association when VHT is available and it is not expected that any configuration of the MU groups is done without it being set.

wifi: mac80211: correctly initialise S1G chandef for STA

2025-09-19T09:56:07+00:00

When moving to the APs channel, ensure we correctly initialise the chandef and perform the required validation. Additionally, if the AP is beaconing on a 2MHz primary, calculate the 2MHz primary center frequency by extracting the sibling 1MHz primary and averaging the frequencies to find the 2MHz primary center frequency.

wifi: mac80211: Support Tx of action frame for NAN

2025-09-19T09:26:22+00:00

Add support for sending management frame over a NAN Device interface: - Declare support for the supported management frames types. - Since action frame transmissions over a NAN Device interface do not necessarily require a channel configuration, e.g., they can be transmitted during DW, modify the Tx path to avoid accessing channel information for NAN Device interface. - In addition modify the points in the Tx path logic to account for cases that a band is not specified in the Tx information.

The command NL80211_CMD_SET_BSS has a number of individual attributes and the driver can advertise which of those it will handle when it is changed by user-space. For drivers providing an empty .change_bss() the callback has been removed.

wifi: mac80211: increase scan_ies_len for S1G

2025-08-26T11:47:21+00:00

Currently the S1G capability element is not taken into account for the scan_ies_len, which leads to a buffer length validation failure in ieee80211_prep_hw_scan() and subsequent WARN in __ieee80211_start_scan(). This prevents hw scanning from functioning. To fix ensure we accommodate for the S1G capability length.
