commit 953b3539 upstream. This patch fixes an issue wherein association would fail on P2P interfaces. This happened because we are checking priv->mode against NL80211_IFTYPE_STATION. While this check is correct for infrastructure stations, it would fail P2P clients for which mode is NL80211_IFTYPE_P2P_CLIENT. Better check would be bss_role which has only 2 values: STA/AP.

commit e2288b66 upstream. Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following call to rt2x00queue_pause_queue() reduce to noop, i.e we do not stop queue in mac80211. To fix that introduce rt2x00queue_pause_queue_nocheck() function, which will stop queue in mac80211 directly. Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit. Note also that reordering operations i.e. first call to rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue() directly is the only available solution to fix the problem without major rework.

commit d9c78e97 upstream. PTR_ERR() returns a signed long type value which is limited by IS_ERR(), it must be a negative number whose range is [-MAX_ERRNO, 0). The bug here returns negative numbers as error codes, then check it by "if (ret < 0)", but -PTR_ERR() is actually positive. The wrong use here leads to failure as below, even panic.

commit e13bae4f upstream. As reported in https://bugzilla.kernel.org/show_bug.cgi?id=60514, the station loop never initialises 'sinfo' and therefore adds up a stack values, leaking stack information (the number of times it adds values is easily obtained another way.) Fix this by initialising the sinfo for each station to add. Signed-off-by:

commit 6b0f3274 upstream. The duplicate retransmission detection code in mac80211 erroneously attempts to do the check for every frame, even frames that don't have a sequence control field or that don't use it (QoS-Null frames.) This is problematic because it causes the code to access data beyond the end of the SKB and depending on the data there will drop packets erroneously. Correct the code to not do duplicate detection for such frames. I found this error while testing AP powersave, it lead to retransmitted PS-Poll frames being dropped entirely as the data beyond the end of the SKB was always zero. Signed-off-by:

There is no software way to reset adpter. This patch add initial configuration and set it in disabled state, to avoid this freeze.

commit 079a036f upstream. Without this patch the driver waits ~1 ms for the UART to become idle. At 115200n8 this time is (theoretically) enough to transfer 11.5 characters (= 115200 bits/s / (10 Bits/char) * 1ms). As the mxs-auart has a fifo size of 16 characters the clock is gated too early. The problem is worse for lower baud rates. This only happens to really shut down the transmitter in the middle of a transfer if /dev/ttyAPPx isn't opened in userspace (e.g. by a getty) but was at least once (because the bootloader doesn't disable the transmitter). So increase the timeout to 20 ms which should be enough for 9600n8, too. Moreover skip gating the clock if the timeout is elapsed. Signed-off-by:

commit 697aebab upstream. A fixup for Apple Mac Mini was lost during the adaption to the generic parser because the fallback for the generic ID 8384:7680 was dropped, and it resulted in the silence output (and maybe other problems). Unfortunately, just adding the missing subsystem ID wasn't enough, in this case. The subsystem ID of this machine is 0000:0100 (what Apple thought...?), and since snd_hda_pick_fixup() doesn't take the vendor id zero into account, the driver ignored this entry. Now it's fixed to regard the vendor id zero as a valid value. Reported-and-tested-by:

commit dd5e6d6a upstream. We can't use dev->mod_index for selecting the interrupt routing entry, because it's not an index into interrupt routing table. It will be even wrong on a machine with 2 CPUs (4 cores). But all needed information is contained in the PAT entries for the serial ports. mod[0] contains the iosapic address and mod_info has some indications for the interrupt input (at least it looks like it). This patch implements the searching for the right iosapic and uses this interrupt input information. Signed-off-by:
