[PATCH] mac80211: tx: Use info->flags in ieee80211_tx_h_select_key()
Posted by Bert Karwatzki 2 weeks, 3 days ago
Without this ieee80211_select_key_8023() is never called and wifi never
connects.

I noticed that in next-20260907 my wifi adapter fails to connect to the
wireless network. As this still worked in v7.3-rc2 I bisected the issue
and found the offending commit to be this merge:

commit d1352d1b277913736903eff185191c4f9723e0de
Merge: 7e615d9c216c 1b60ed34f712
Author: Mark Brown <broonie@kernel.org>
Date:   Mon Sep 7 13:26:24 2026 +0100

    Merge branch 'for-next' of https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git

So I examined the patch created by
git diff 7e615d9c216c d1352d1b2779
by applying it piece by piece to commit 7e615d9c216c.

The result of this procedure was the patch above as a minimal fix in
next-20260907.

The wirless hardware used is this:
09:00.0 Network controller [0280]: MEDIATEK Corp. MT7925 802.11be 160MHz 2x2 PCIe Wireless Network Adapter [Filogic 360] [14c3:7925]

Using printk()s in ieee80211_select_key_8023() (in next-20260907) I
noticed that ieee80211_select_key_8023() is never called when using
the info->control.flags test.
