-Subject: [PATCH] mac80211: mesh: flush mesh paths unconditionally
-
-Currently, the mesh paths associated with a nexthop station are cleaned
-up in the following code path:
-
- __sta_info_destroy_part1
- synchronize_net()
- __sta_info_destroy_part2
- -> cleanup_single_sta
- -> mesh_sta_cleanup
- -> mesh_plink_deactivate
- -> mesh_path_flush_by_nexthop
-
-However, there are a couple of problems here:
-
-1) the paths aren't flushed at all if the MPM is running in userspace
- (e.g. when using wpa_supplicant or authsae)
-
-2) there is no synchronize_rcu between removing the path and readers
- accessing the nexthop, which means the following race is possible:
-
-CPU0 CPU1
-~~~~ ~~~~
- sta_info_destroy_part1()
- synchronize_net()
-rcu_read_lock()
-mesh_nexthop_resolve()
- mpath = mesh_path_lookup()
- [...] -> mesh_path_flush_by_nexthop()
- sta = rcu_dereference(
- mpath->next_hop)
- kfree(sta)
- access sta <-- CRASH
-
-Fix both of these by unconditionally flushing paths before destroying
-the sta, and by adding a synchronize_net() after path flush to ensure
-no active readers can still dereference the sta.
-
-Fixes this crash:

+Subject: [PATCH] mac80211: add NEED_ALIGNED4_SKBS hw flag
+
+HW/driver should set NEED_ALIGNED4_SKBS flag in case
+require aligned skbs to four-byte boundaries.
+This affect only TX direction.
+
+Padding is added after ieee80211_hdr, before IV/LLC.
+
+Before we have to do memmove(hdrlen) twice in the
+dirver. Once before we pass this to HW and next
+in tx completion (to be sure monitor will report
+this tx frame correctly).
+
+With this patch we can skip this memmove() and save CPU.
+
+Currently this was tested with ath9k, both hw/sw crypt for
+wep/tkip/ccmp.

+Subject: [PATCH] ath10k: Fix sending NULL/ Qos NULL data frames for
+ QCA99X0 and later
+
+For chipsets like QCA99X0, IPQ4019 and later we are not getting proper
+NULL func status (always acked/successs !!) when hostapd does a
+PROBE_CLIENT via nullfunc frames when the station is powered off
+abruptly (inactive timer probes client via null func after the inactive
+time reaches beyond the threshold). Fix this by disabling the workaround
+(getting the ACK status of NULL func frames by sending via HTT mgmt-tx
+ path) introduced by the change ("ath10k: fix beacon loss handling ")
+for QCA99X0 and later chipsets. The normal tx path provides the proper
+ACK status for NULL data frames. As of now disable this workaround for
+chipsets QCA99X0 and later, once the 10.1 firmware is obselete we can
+completely get rid of this workaround for all the chipsets

-This results in reporting of rx frames (with CCK rates)
-totally wrong for QCA99X0, QCA4019. Fix this by having
-separate CCK rate table for these chipsets with rev2 suffix
-and registering the correct rate mapping to mac80211 based on

+Subject: [PATCH] cfg80211: fix proto in ieee80211_data_to_8023 for frames
+ without LLC header
+
+The PDU length of incoming LLC frames is set to the total skb payload size
+in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly
+includes the length of the IEEE 802.11 header.
+
+The resulting LLC frame header has a too large PDU length, causing the
+llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming
+skb, effectively breaking STP.
+
+Solve the problem by properly substracting the IEEE 802.11 frame header size
+from the PDU length, allowing the LLC processor to pick up the incoming
+control messages.
+
+Special thanks to Gerry Rozema for tracking down the regression and proposing
+a suitable patch.
+
+Fixes: 2d1c304cb2d5 ("cfg80211: add function for 802.3 conversion with separate output buffer")

-Subject: [PATCH] ath10k: fix deadlock while processing rx_in_ord_ind
-
-commit 5c86d97bcc1d ("ath10k: combine txrx and replenish task")
-introduced deadlock while processing rx in order indication message
-for qca6174 based devices. While merging replenish and txrx tasklets,
-replenish task should be called out of htt rx ring locking since it
-is also try to acquire the same lock.
-
-Unfortunately this issue is not exposed by other solutions (qca988x,
-qca99x0 & qca4019), as rx_in_ord_ind message is specific to qca6174
-based devices. This patch fixes
-
-=============================================
-[ INFO: possible recursive locking detected ]
