Since booting into a kernel with this diff, I've started seeing the
following messages on my OpenBSD AP that uses athn(4):
Apr 30 02:13:54 smetana /bsd: athn0: Michael MIC failure
Apr 30 02:14:40 smetana /bsd: athn0: Michael MIC failure
Apr 30 02:16:43 smetana /bsd: athn0: Michael MIC failure
Apr 30 02:16:43 smetana /bsd: athn0: HostAP will be disabled for 69 seconds as
a countermeasure against TKIP key cracking attempts
Apr 30 02:21:49 smetana /bsd: athn0: Michael MIC failure
Apr 30 02:21:49 smetana /bsd: athn0: HostAP will be disabled for 61 seconds as
a countermeasure against TKIP key cracking attempts
Apr 30 02:24:17 smetana /bsd: athn0: Michael MIC failure
Apr 30 02:24:17 smetana /bsd: athn0: HostAP will be disabled for 82 seconds as
a countermeasure against TKIP key cracking attempts
Apr 30 02:25:52 smetana /bsd: athn0: Michael MIC failure
That is with:
iwm0 at pci1 dev 0 function 0 "Intel Dual Band Wireless-AC 9260" rev 0x29, msix
iwm0: hw rev 0x320, fw ver 34.3125811985.0
This also could be related to the earlier diff, so I'm reverting back
to a snapshot kernel for now.
The AP is running:
OpenBSD 6.9 (GENERIC.MP) #0: Thu Apr 15 17:07:30 CEST 2021
kette...@smetana.sibelius.xs4all.nl:/home/kettenis/src/athn/sys/arch/arm64/c
Which is a kernel I built to test athn.c r1.110.
Will keep you posted...
Cheers,
Mark
