qca9980 GTK rekey fails on 4-addr bridges about ath10k-ct HOT 4 OPEN

If I build you a set of firmware images, would you be interested in trying to bisect the problem? The procedure is to copy the firmware blob onto your owrt system and reboot and test, you should not actually need to build new owrt image. If it is a bug I introduced, then the bisect should find it and probably I can fix it.

I am willing to do any testing you prescribe. I have my test environment ready to go.

My skill level is "overachieving bash hacker", which isn't a complement. I can build my own images, apply patches, and that sort of thing, but anything beyond a hello-word in C is a no-go and I don't know anything about device firmware.

I believe I am suffering from this same problem. R7800 as master (WDS, platform is ipq806x with qca9880), MR8300 as client (has a third radio so I don't run AP+STA, ipq40xx), WPA2 with 802.11w optional. I've 100% drops every 6000 seconds on my periodic 1s ping tests between both routers, exactly my GTK rekey period set. ct drivers on both ends, ath10k on both ends. I believe (but need to retest) I can replicate them on WPA3 as well.

Will try lowering the rekey period.

Noting as well https://patchwork.kernel.org/project/ath10k/patch/[email protected]/ seems to be related?

Note my comment above:

I have noticed the failure rate increases as wpa_group_rekey on hostapd is increased: 3% failure at 60, 25% at 600, 87% at 3600, and 99% at 86400

You will need to change your wpa_group_rekey to sub-1-hour to be successful even some of the time. It might just be better to set it really high, though I don't know what the maximum is.

I am still willing to test this out, I just got busy and never really followed up on this.
