ath10k has a replay detection issue which was fixed in v4.14 and we would like to get this security fix also to linux-stable-4.4.But for that it depends on 3 mac80211 patches so the below mac80211 commits needs to be picked first in the same order and then apply this patchset.
f980ebc058c2 : mac80211: allow not sending MIC up from driver for HW crypto f631a77ba920 : mac80211: allow same PN for AMSDU sub-frames cef0acd4d7d4 : mac80211: Add RX flag to indicate ICV stripped
These patches should be applied in that order(commit f980ebc058c2 first) and they should apply cleanly with 3-way merge.
Sriram R (2): ath10k: Add new hw param to identify alignment for different chipsets ath10k: rebuild crypto header in rx data frames

Chipset QCA99X0 doesnot have rx_hdr_status padded to align in 4-byte boundary.Hence define a new hw_params field to handle different alignment behaviour between different chipsets.

I feel this breaks since the above mentioned mac80211 commits are not available in this queue.

Could you please check after these commits are queued as well before this patch is applied.

Ugh, you are right, I missed that in the cover leter, my fault. I'll blame the jet-lag :)
I'll go drop the first patch for now, and then look at all of these again at the end of the week for the next round of releases.

Hi Greg,
This patch along with its dependency patches (in the following order)
f980ebc058c2 : mac80211: allow not sending MIC up from driver for HW crypto f631a77ba920 : mac80211: allow same PN for AMSDU sub-frames cef0acd4d7d4 : mac80211: Add RX flag to indicate ICV stripped [PATCH 1/2 linux-stable-4.4] ath10k: Add new hw param to identify alignment for different chipsets
Hi Greg,
I feel this breaks since the above mentioned mac80211 commits are not available in this queue.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/diff...
Could you please check after these commits are queued as well before this patch is applied.
Please let me know if i miss something here so i could check from my side as well.
Ugh, you are right, I missed that in the cover leter, my fault. I'll blame the jet-lag :)
I'll go drop the first patch for now, and then look at all of these again at the end of the week for the next round of releases.
thanks,
greg k-h
Sure, Thanks Greg.
Regards, Sriram.R

These patches should be applied in that order(commit f980ebc058c2 first) and they should apply cleanly with 3-way merge.
Thanks, now queued up.
