wifi: rsi_91x_usb: do not pause rfkill polling when stopping mac80211

2026-03-19T08:07:16Z

Removing rsi_91x USB adapter could cause rtnetlink to lock up. When rsi_mac80211_stop is called, wiphy_lock is locked. Call to wiphy_rfkill_stop_polling would wait until the work queue has finished, but because the work queue waits for wiphy_lock, that would never happen. Moving the call to rsi_disconnect avoids the lock up. Signed-off-by: Ville Nummela Link: https://patch.msgid.link/20260318081912.87744-1-ville.nummela@kempower.com Signed-off-by: Johannes Berg

wifi: rsi: Don't default to -EOPNOTSUPP in rsi_mac80211_config

2026-03-02T11:06:03Z

This triggers a WARN_ON in ieee80211_hw_conf_init and isn't the expected behavior from the driver - other drivers default to 0 too.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

net: remove unnecessary module_init/exit functions

2026-02-03T01:25:23Z

Many network drivers have unnecessary empty module_init and module_exit functions. Remove them (including some that just print a message). Note that if a module_init function exists, a module_exit function must also exist; otherwise, the module cannot be unloaded.

wifi: rsi: sdio: Migrate to use sdio specific shutdown function

This saves a cast in the driver. The motivation is stop using the callback .shutdown in rsi_driver.drv to make it possible to drop that.

wifi: rsi: Fix memory corruption due to not set vif driver data size

2026-01-12T18:34:56Z

The struct ieee80211_vif contains trailing space for vif driver data, when struct ieee80211_vif is allocated, the total memory size that is allocated is sizeof(struct ieee80211_vif) + size of vif driver data. The size of vif driver data is set by each WiFi driver as needed. The RSI911x driver does not set vif driver data size, no trailing space for vif driver data is therefore allocated past struct ieee80211_vif . The RSI911x driver does however use the vif driver data to store its vif driver data structure "struct vif_priv". An access to vif->drv_priv leads to access out of struct ieee80211_vif bounds and corruption of some memory. In case of the failure observed locally, rsi_mac80211_add_interface() would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv; vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member struct list_head new_flows . The flow = list_first_entry(head, struct fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus address, which when accessed causes a crash. The trigger is very simple, boot the machine with init=/bin/sh , mount devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1", "ip link set wlan0 down" and the crash occurs. Fix this by setting the correct size of vif driver data, which is the size of "struct vif_priv", so that memory is allocated and the driver can store its driver data in it, instead of corrupting memory around it.

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

2025-06-24T13:19:27Z

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.
