Subject: iwlwifi: 9260: Spurious "Unhandled alg: 0x707" and 0x71b
Date: Fri, 16 Aug 2019 16:55:27 +0800
Message-ID: <badc218b-ea1f-3697-b1f2-3ebb294d9849@in04.sg> (raw)

Hi,

I've been getting "Unhandled alg: 0x707" or 0x71b randomly
on my Intel 9260. It seems to happen most often when it
associates to a new AP (or roams to a different one that
has the same SSID/authentication). It also seems to happen
only with particular APs. (I don't have access to the APs,
so there's not much I know about them.)

I applied the two patches mentioned in Bugzilla #203593[1]
i.e. "iwlwifi: mvm: Allow multicast data frames only when
associated" and "iwlwifi: mvm: Allow multicast data frames
only when authorized" on top of iwlwifi in 5.2.8, which
improved the situation a lot, but it still happens pretty
frequently.

[1]: https://bugzilla.kernel.org/show_bug.cgi?id=203593

I'll try to collect some debug data soon. Also, I'll try
to see if my 8260 has the same issues.

Is there anything else I should try or any other patches I
should backport?

Thanks.
