Hi
Since the merge window opened I've been unable to see any wireless
networks or join my usual access point
I bisected this to:
9ed4f91628737c820af6a1815b65bc06bd31518f is the first bad commit
commit 9ed4f91628737c820af6a1815b65bc06bd31518f
Author: Ryan Hsu <[email protected]>
Date: Tue Jan 16 11:43:49 2018 +0200
ath10k: add sanity check to ie_len before parsing fw/board ie
Validate ie_len after the alignment padding before access the buffer
to avoid potential overflow.
Signed-off-by: Ryan Hsu <[email protected]>
Signed-off-by: Kalle Valo <[email protected]>
And I can confirm that reverting the patch makes things work again (attached)
Device:
3c:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac
Wireless Network Adapter [168c:003e] (rev 32)
Firmware:
https://github.com/kvalo/ath10k-firmware
ath10k-firmware/QCA6174/hw3.0/4.4.1.c1
There was nothing obvious in the dmesg
Regards
Mike
