+ ath9k_hw: toggle weak signal detection in AP mode on older chipsets
+
+ The commit 80b4205b "ath9k: Fix OFDM weak signal detection for AP mode"
+ prevented weak signal detection changes from taking effect in AP mode on
+ all chipsets, claiming it is "not allowed".
+
+ The main reason for not disabling weak signal detection in AP mode is
+ that typically beacon RSSI is used to track whether it is needed to
+ boost range, and this is unavailable in AP mode for obvious reasons.
+
+ The problem with not disabling weak signal detection is that older
+ chipsets are very sensitive to high PHY error counts. When faced with
+ heavy noise, this can lead to an excessive amount of "Failed to stop
+ TX DMA" errors in the field.

+ mac80211: fix station wakeup powersave race
+
+ Consider the following (relatively unlikely) scenario:
+ 1) station goes to sleep while frames are buffered in driver
+ 2) driver blocks wakeup (until no more frames are buffered)
+ 3) station wakes up again
+ 4) driver unblocks wakeup
+
+ In this case, the current mac80211 code will do the following:
+ 1) WLAN_STA_PS_STA set
+ 2) WLAN_STA_PS_DRIVER set
+ 3) - nothing -
+ 4) WLAN_STA_PS_DRIVER cleared
+
+ As a result, no frames will be delivered to the client, even
+ though it is awake, until it sends another frame to us that
+ triggers ieee80211_sta_ps_deliver_wakeup() in sta_ps_end().
+
+ Since we now take the PS spinlock, we can fix this while at
+ the same time removing the complexity with the pending skb
+ queue function. This was broken since my commit 50a9432daeec
+ ("mac80211: fix powersaving clients races") due to removing
+ the clearing of WLAN_STA_PS_STA in the RX path.
+
+ While at it, fix a cleanup path issue when a station is
+ removed while the driver is still blocking its wakeup.

+
+ mac80211: insert stations before adding to driver
+
+ There's a race condition in mac80211 because we add stations
+ to the internal lists after adding them to the driver, which
+ means that (for example) the following can happen:
+ 1. a station connects and is added
+ 2. first, it is added to the driver
+ 3. then, it is added to the mac80211 lists
+
+ If the station goes to sleep between steps 2 and 3, and the
+ firmware/hardware records it as being asleep, mac80211 will
+ never instruct the driver to wake it up again as it never
+ realized it went to sleep since the RX path discarded the
+ frame as a "spurious class 3 frame", no station entry was
+ present yet.
+
+ Fix this by adding the station in software first, and only
+ then adding it to the driver. That way, any state that the
+ driver changes will be reflected properly in mac80211's
+ station state. The problematic part is the roll-back if the
+ driver fails to add the station, in that case a bit more is
+ needed. To not make that overly complex prevent starting BA
+ sessions in the meantime.

+
+ mac80211: fix AP powersave TX vs. wakeup race
+
+ There is a race between the TX path and the STA wakeup: while
+ a station is sleeping, mac80211 buffers frames until it wakes
+ up, then the frames are transmitted. However, the RX and TX
+ path are concurrent, so the packet indicating wakeup can be
+ processed while a packet is being transmitted.
+
+ This can lead to a situation where the buffered frames list
+ is emptied on the one side, while a frame is being added on
+ the other side, as the station is still seen as sleeping in
+ the TX path.
+
+ As a result, the newly added frame will not be send anytime
+ soon. It might be sent much later (and out of order) when the
+ station goes to sleep and wakes up the next time.
+
+ Additionally, it can lead to the crash below.
+
+ Fix all this by synchronising both paths with a new lock.
+ Both path are not fastpath since they handle PS situations.
+
+ In a later patch we'll remove the extra skb queue locks to
+ reduce locking overhead.

+ rtl8187: fix regression on MIPS without coherent DMA
+
+ This patch fixes regression caused by commit a16dad77634 "MIPS: Fix
+ potencial corruption". That commit fixes one corruption scenario in
+ cost of adding another one, which actually start to cause crashes
+ on Yeeloong laptop when rtl8187 driver is used.
+
+ For correct DMA read operation on machines without DMA coherence, kernel
+ have to invalidate cache, such it will refill later with new data that
+ device wrote to memory, when that data is needed to process. We can only
+ invalidate full cache line. Hence when cache line includes both dma
+ buffer and some other data (written in cache, but not yet in main
+ memory), the other data can not hit memory due to invalidation. That
+ happen on rtl8187 where struct rtl8187_priv fields are located just
+ before and after small buffers that are passed to USB layer and DMA
+ is performed on them.
+
+ To fix the problem we align buffers and reserve space after them to make
+ them match cache line.
+
+ This patch does not resolve all possible MIPS problems entirely, for
+ that we have to assure that we always map cache aligned buffers for DMA,
+ what can be complex or even not possible. But patch fixes visible and
+ reproducible regression and seems other possible corruptions do not
+ happen in practice, since Yeeloong laptop works stable without rtl8187
+ driver.

+
+ IQ calibration post-processing for AR955x is different

+
+ For non-AR955x chips, the iqcal_idx (which will be used

+ cfg80211: consider existing DFS interfaces
+
+ It was possible to break interface combinations in
+ the following way:
+
+ combo 1: iftype = AP, num_ifaces = 2, num_chans = 2,
+ combo 2: iftype = AP, num_ifaces = 1, num_chans = 1, radar = HT20
+
+ With the above interface combinations it was
+ possible to:
+
+ step 1. start AP on DFS channel by matching combo 2
+ step 2. start AP on non-DFS channel by matching combo 1
+
+ This was possible beacuse (step 2) did not consider
+ if other interfaces require radar detection.
+
+ The patch changes how cfg80211 tracks channels -
+ instead of channel itself now a complete chandef
+ is stored.

+ cfg80211: fix channel configuration in IBSS join
+
+ When receiving an IBSS_JOINED event select the BSS object
+ based on the {bssid, channel} couple rather than the bssid
+ only.
+ With the current approach if another cell having the same
+ BSSID (but using a different channel) exists then cfg80211
+ picks up the wrong BSS object.
+ The result is a mismatching channel configuration between
+ cfg80211 and the driver, that can lead to any sort of
+ problem.
+
+ The issue can be triggered by having an IBSS sitting on
+ given channel and then asking the driver to create a new
+ cell using the same BSSID but with a different frequency.
+ By passing the channel to cfg80211_get_bss() we can solve
+ this ambiguity and retrieve/create the correct BSS object.
+ All the users of cfg80211_ibss_joined() have been changed
+ accordingly.
+
+ Moreover WARN when cfg80211_ibss_joined() gets a NULL
+ channel as argument and remove a bogus call of the same
+ function in ath6kl (it does not make sense to call
+ cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

+
+ Fix this by introducing a new helper ieee80211_is_bufferable_mmpdu()

+ mac80211: fix fragmentation code, particularly for encryption
+
+ The "new" fragmentation code (since my rewrite almost 5 years ago)
+ erroneously sets skb->len rather than using skb_trim() to adjust
+ the length of the first fragment after copying out all the others.
+ This leaves the skb tail pointer pointing to after where the data
+ originally ended, and thus causes the encryption MIC to be written
+ at that point, rather than where it belongs: immediately after the
+ data.
+
+ The impact of this is that if software encryption is done, then
+ a) encryption doesn't work for the first fragment, the connection
+ becomes unusable as the first fragment will never be properly
+ verified at the receiver, the MIC is practically guaranteed to
+ be wrong
+ b) we leak up to 8 bytes of plaintext (!) of the packet out into
+ the air
+
+ This is only mitigated by the fact that many devices are capable
+ of doing encryption in hardware, in which case this can't happen
+ as the tail pointer is irrelevant in that case. Additionally,
+ fragmentation is not used very frequently and would normally have
+ to be configured manually.
+
+ Fix this by using skb_trim() properly.

+ cfg80211: send scan results from work queue
+
+ Due to the previous commit, when a scan finishes, it is in theory
+ possible to hit the following sequence:
+ 1. interface starts being removed
+ 2. scan is cancelled by driver and cfg80211 is notified
+ 3. scan done work is scheduled
+ 4. interface is removed completely, rdev->scan_req is freed,
+ event sent to userspace but scan done work remains pending
+ 5. new scan is requested on another virtual interface
+ 6. scan done work runs, freeing the still-running scan
+
+ To fix this situation, hang on to the scan done message and block
+ new scans while that is the case, and only send the message from
+ the work function, regardless of whether the scan_req is already
+ freed from interface removal. This makes step 5 above impossible
+ and changes step 6 to be
+ 5. scan done work runs, sending the scan done message
+
+ As this can't work for wext, so we send the message immediately,

+
+ cfg80211: fix scan done race
+
+ When an interface/wdev is removed, any ongoing scan should be
+ cancelled by the driver. This will make it call cfg80211, which
+ only queues a work struct. If interface/wdev removal is quick
+ enough, this can leave the scan request pending and processed
+ only after the interface is gone, causing a use-after-free.
+
+ Fix this by making sure the scan request is not pending after
+ the interface is destroyed. We can't flush or cancel the work
+ item due to locking concerns, but when it'll run it shouldn't
+ find anything to do. This leaves a potential issue, if a new
+ scan gets requested before the work runs, it prematurely stops
+ the running scan, potentially causing another crash. I'll fix
+ that in the next patch.
+
+ This was particularly observed with P2P_DEVICE wdevs, likely
+ because freeing them is quicker than freeing netdevs.

+ While at it, reset the driver_smps_mode when the ap is

+ nl80211: send event when AP operation is stopped
+
+ There are a few cases, e.g. suspend, where an AP interface is
+ stopped by the kernel rather than by userspace request, most
+ commonly when suspending. To let userspace know about this,
+ send the NL80211_CMD_STOP_AP command as an event every time
+ an AP interface is stopped. This also happens when userspace
+ did in fact request the AP stop, but that's not a problem.
+
+ For full-MAC drivers this may need to be extended to also
+ cover cases where the device stopped the AP operation for
+ some reason, this a bit more complicated because then all
+ cfg80211 state also needs to be reset; such API is not part

+ nl80211: fix scheduled scan RSSI matchset attribute confusion
+
+ The scheduled scan matchsets were intended to be a list of filters,
+ with the found BSS having to pass at least one of them to be passed
+ to the host. When the RSSI attribute was added, however, this was
+ broken and currently wpa_supplicant adds that attribute in its own
+ matchset; however, it doesn't intend that to mean that anything
+ that passes the RSSI filter should be passed to the host, instead
+ it wants it to mean that everything needs to also have higher RSSI.
+
+ This is semantically problematic because we have a list of filters
+ like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which
+ one should be OR'ed and which one AND'ed.
+
+ To fix this, move the RSSI filter attribute into each matchset. As
+ we need to stay backward compatible, treat a matchset with only the
+ RSSI attribute as a "default RSSI filter" for all other matchsets,
+ but only if there are other matchsets (an RSSI-only matchset by
+ itself is still desirable.)
+
+ To make driver implementation easier, keep a global min_rssi_thold
+ for the entire request as well. The only affected driver is ath6kl.
+
+ I found this when I looked into the code after Raja Mani submitted
+ a patch fixing the n_match_sets calculation to disregard the RSSI,
+ but that patch didn't address the semantic issue.
