The ath patch number is already large and adding other patch for ath11k will add more confusion with the patch numbering. Since the support of ath11k based device is imminent, prepare the mac80211 ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k (empty for now).

Subject: [PATCH] ath10k: Fix TKIP Michael MIC verification for PCIe
|
|
|
|
TKIP Michael MIC was not verified properly for PCIe cases since the
|
|
validation steps in ieee80211_rx_h_michael_mic_verify() in mac80211 did
|
|
not get fully executed due to unexpected flag values in
|
|
ieee80211_rx_status.
|
|
|
|
Fix this by setting the flags property to meet mac80211 expectations for
|
|
performing Michael MIC validation there. This fixes CVE-2020-26141. It
|
|
does the same as ath10k_htt_rx_proc_rx_ind_hl() for SDIO which passed
|
|
MIC verification case. This applies only to QCA6174/QCA9377 PCIe.
|
|
|
|
Tested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00110-QCARMSWP-1
