wifi: iwlegacy: avoid fortify warning

2023-02-17T09:35:54+00:00

There are two different alive messages, the "init" one is bigger than the other one, so we have a fortify read warn here. Avoid it by copying from the variable-sized 'raw' instead.

wifi: iwl4965: Add missing check for create_singlethread_workqueue()

2023-02-13T15:17:27+00:00

Add the check for the return value of the create_singlethread_workqueue() in order to avoid NULL pointer dereference.

wifi: iwlegacy: common: don't call dev_kfree_skb() under spin_lock_irqsave()

2022-12-14T12:21:21+00:00

It is not allowed to call consume_skb() from hardware interrupt context or with interrupts being disabled. So replace dev_kfree_skb() with dev_consume_skb_irq() under spin_lock_irqsave(). Compile tested only.

wifi: iwlegacy: remove redundant variable len

2022-11-08T07:40:18+00:00

Variable len is being assigned and modified but it is never used. The variable is redundant and can be removed.

wifi: mac80211: add wake_tx_queue callback to drivers

2022-10-10T09:00:03+00:00

mac80211 is fully switching over to the internal TX queue (iTXQ) implementation. Update all drivers not yet providing the now mandatory wake_tx_queue() callback. As an side effect the netdev interfaces of all updated drivers will switch to the noqueue qdisc. Signed-off-by: Alexander Wetzel [add staging drivers] Signed-off-by: Johannes Berg

iwlegacy: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper

2022-09-28T06:45:15+00:00

Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

wifi: mac80211: make smps_mode per-link

2022-09-06T08:11:44+00:00

The SMPS power save mode needs to be per-link rather than being shared for all links. As such, move it into struct ieee80211_link_sta. Signed-off-by: Benjamin Berg Signed-off-by: Johannes Berg

Merge wireless/main to get the rx.link fix, which is needed for further work in this area. Signed-off-by: Johannes Berg

wifi: move from strlcpy with unused retval to strscpy

2022-09-02T08:47:22+00:00

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.
