Hello.

Hi Tetsuo,

quoted

I found that your patch was applied. But since the reproducer tested only 0 byte
case, I think that rejecting only less than sizeof(struct htc_frame_hdr) bytes
is not sufficient.

More complete patch with Ack from Toke is waiting at
https://lkml.kernel.org/r/7acfa1be-4b5c-b2ce-de43-95b0593fb3e5@I-love.SAKURA.ne.jp .

Thanks for letting me know! I just checked that your patch indeed
fixes the issue I am facing.
If it is more complete, I think we'd indeed better use yours.

I recognized that "ath9k: fix an uninit value use in ath9k_htc_rx_msg()" is
local to KMSAN tree.
https://github.com/google/kmsan/commit/d891e35583bf2e81ccc7a2ea548bf7cf47329f40

I actually did a rebase of KMSAN tree to v6.0-rc2 yesterday and
dropped that patch (picked yours instead).
Thanks for the heads-up!
