Subject: [PATCH] ath9k: dynack: use authentication messages for 'late' ack
In order to properly support dynack in ad-hoc mode running
wpa_supplicant, take into account authentication frames for
'late ack' detection. This patch has been tested on devices
mounted on offshore high-voltage stations connected through
~24Km link

Subject: [PATCH] brcmutil: really fix decoding channel info for 160 MHz
bandwidth
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previous commit /adding/ support for 160 MHz chanspecs was incomplete.
It didn't set bandwidth info and didn't extract control channel info. As
the result it was also using uninitialized "sb" var.
This change has been tested for two chanspecs found to be reported by
some devices/firmwares:
1) 60/160 (0xee32)
Before: chnum:50 control_ch_num:36
After: chnum:50 control_ch_num:60
2) 120/160 (0xed72)
Before: chnum:114 control_ch_num:100
After: chnum:114 control_ch_num:120

[ 31.096533] Disabling lock debugging due to kernel taint
It appears that when trying to determine the length of the string in the
alternate firmware path, we make the mistake of not handling the case
where the firmware path is empty correctly. Since strlen(mp_path) can
return 0, we'll end up accessing mp_path[-1] when the firmware_path
isn't provided through the module arguments.
So, fix this by just setting the end char to '\0' by default, and only
changing it if we have a non-zero length. Additionally, use strnlen()
with BRCMF_FW_ALTPATH_LEN instead of strlen() just to be extra safe.

Subject: [PATCH] brcmfmac: fix roamoff=1 modparam
When the update_connect_param callback is set, nl80211 expects the flag
WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is
only set when modparam roamoff=0, while the callback is set
unconditionally. Since commit 7f9a3e150ec7 this causes a warning in
wiphy_register, which breaks brcmfmac.
Disable the update_connect_param callback when roamoff=0 to fix this.
Fixes: 7f9a3e150ec7 ("nl80211: Update ERP info using NL80211_CMD_UPDATE_CONNECT_PARAMS")

Subject: [PATCH] mac80211: free skb fraglist before freeing the skb
mac80211 uses the frag list to build AMSDU. When freeing
the skb, it may not be really freed, since someone is still
holding a reference to it.
In that case, when TCP skb is being retransmitted, the
pointer to the frag list is being reused, while the data
in there is no longer valid.
Since we will never get frag list from the network stack,
as mac80211 doesn't advertise the capability, we can safely
free and nullify it before releasing the SKB.

Subject: [PATCH] mac80211: fix reordering of buffered broadcast packets
If the buffered broadcast queue contains packets, letting new packets bypass
that queue can lead to heavy reordering, since the driver is probably throttling
transmission of buffered multicast packets after beacons.
Keep buffering packets until the buffer has been cleared (and no client
is in powersave mode).

Subject: [PATCH 1/3] mac80211: fix a kernel panic when TXing after TXQ
teardown
Recently TXQ teardown was moved earlier in ieee80211_unregister_hw(),
to avoid a use-after-free of the netdev data. However, interfaces
aren't fully removed at the point, and cfg80211_shutdown_all_interfaces
can for example, TX a deauth frame. Move the TXQ teardown to the
point between cfg80211_shutdown_all_interfaces and the free of
netdev queues, so we can be sure they are torn down before netdev
is freed, but after there is no ongoing TX.
Fixes: 77cfaf52eca5 ("mac80211: Run TXQ teardown code before de-registering interfaces")

If validate_pae_over_nl80211() were to fail in nl80211_crypto_settings(),
we might leak the 'connkeys' allocation. Fix this.

Subject: [PATCH] mac80211: ensure that management tx skbs have encryption
tailroom
Some drivers use IEEE80211_KEY_FLAG_SW_MGMT_TX to indicate that management
frames need to be software encrypted. Since normal data packets are still
encrypted by the hardware, crypto_tx_tailroom_needed_cnt gets decremented
after key upload. This can lead to passing skbs to ccmp_encrypt_skb, which
don't have the needed tailroom for software encryption.
Change the code to add tailroom for encrypted management packets, even if
crypto_tx_tailroom_needed_cnt is 0.
