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

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

wifi: cfg80211/mac80211: Add support to get radio index

2025-06-24T13:19:27+00:00

Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

wifi: ath6kl: remove WARN on bad firmware input

2025-06-18T07:04:56+00:00

If the firmware gives bad input, that's nothing to do with the driver's stack at this point etc., so the WARN_ON() doesn't add any value. Additionally, this is one of the top syzbot reports now. Just print a message, and as an added bonus, print the sizes too.

wifi: cfg80211: send MLO links tx power info in GET_INTERFACE

2024-12-04T15:14:46+00:00

Currently, TX power is reported on interface/wdev level as part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links can be part of an interface/wdev and hence its necessary to report the TX power of each link. Add support to send tx power for all valid links of an MLD as part of NL80211_CMD_GET_INTERFACE request. As far as userspace is concerned, there is no behavioral change for Non-ML Interfaces. For ML interfaces, userspace should fetch TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.
