+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] rt2x00: fix monitor mode regression
-
-Since commit df1404650ccbfeb76a84f301f22316be0d00a864 monitor mode for rt2x00
-has been made effectively useless because the hardware filter is configured to
-drop packets whose intended recipient is not the device, regardless of the
-presence of monitor mode interfaces.
-
-This patch fixes this regression by adding explicit monitor mode support, and
-configuring the hardware filter accordingly.

-
-One crash issue be found on ar9300: RTC_RC reg read leads crash, leading
-the data bus error, due to RTC_RC reg write not happen properly.
-
-Warm Reset trigger in continuous beacon stuck for one of the customer for
-other chip, noticed the MAC was stuck in RTC reset. After analysis noticed
-DMA did not complete when RTC was put in reset.
-
-So, before resetting the MAC need to make sure there are no pending DMA
-transactions because this reset does not reset all parts of the chip.
-
-The 12th and 11th bit of MAC _DMA_CFG register used to do that.
- 12 cfg_halt_ack 0x0
- 0 DMA has not yet halted
- 1 DMA has halted
- 11 cfg_halt_req 0x0
- 0 DMA logic operates normally
- 1 Request DMA logic to stop so software can reset the MAC
-
-The Bit [12] of this register indicates when the halt has taken effect or
-not. the DMA halt IS NOT recoverable; once software sets bit [11] to
-request a DMA halt, software must wait for bit [12] to be set and reset
-the MAC.
-
-So, the same thing we implemented for ar9580 chip.

-Subject: [PATCH] mac80211: fix unnecessary frame drops in mesh fwding
-
-The ieee80211_queue_stopped() expects hw queue
-number but it was given raw WMM AC number instead.
-
-This could cause frame drops and problems with
-traffic in some cases - most notably if driver
-doesn't map AC numbers to queue numbers 1:1 and
-uses ieee80211_stop_queues() and
-ieee80211_wake_queue() only without ever calling
-ieee80211_wake_queues().
-
-On ath10k it was possible to hit this problem in
-the following case:
-
- 1. wlan0 uses queue 0
- (ath10k maps queues per vif)
- 2. offchannel uses queue 15
- 3. queues 1-14 are unused
- 4. ieee80211_stop_queues()
- 5. ieee80211_wake_queue(q=0)
- 6. ieee80211_wake_queue(q=15)
- (other queues are not woken up because both
- driver and mac80211 know other queues are
- unused)
- 7. ieee80211_rx_h_mesh_fwding()
- 8. ieee80211_select_queue_80211() returns 2
- 9. ieee80211_queue_stopped(q=2) returns true
- 10. frame is dropped (oops!)

-Subject: [PATCH] mac80211: Requeue work after scan complete for all VIF
- types.
-
-During a sw scan ieee80211_iface_work ignores work items for all vifs.
-However after the scan complete work is requeued only for STA, ADHOC
-and MESH iftypes.
-
-This occasionally results in event processing getting delayed/not
-processed for iftype AP when it coexists with a STA. This can result
-in data halt and eventually disconnection on the AP interface.

-When joining IBSS a full scan should be initiated in order to search
-for existing cell, unless the fixed_channel parameter was set.
-A default channel to create the IBSS on if no cell was found is
-provided as well.
-However - a scan is initiated only on the default channel provided
-regardless of whether ifibss->fixed_channel is set or not, with the
-obvious result of the cell not joining existing IBSS cell that is

-Subject: [PATCH] mac80211: Parse legacy and HT rate in injected frames
-
-Drivers/devices without their own rate control algorithm can get the
-information what rates they should use from either the radiotap header of
-injected frames or from the rate control algorithm. But the parsing of the
-legacy rate information from the radiotap header was removed in commit
-e6a9854b05c1 ("mac80211/drivers: rewrite the rate control API").
-
-The removal of this feature heavily reduced the usefulness of frame
-injection when wanting to simulate specific transmission behavior. Having
-rate parsing together with MCS rates and retry support allows a fine
-grained selection of the tx behavior of injected frames for these kind of
-tests.

-Subject: [PATCH] brcmfmac: fix setting primary channel for 80 MHz width
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-First of all it changes the way we calculate primary channel offset. If
-we use e.g. 80 MHz channel with primary frequency 5180 MHz (which means
-center frequency is 5210 MHz) it makes sense to calculate primary offset
-as -30 MHz.
-Then it fixes values we compare primary_offset with. We were comparing
-offset in MHz against -2 or 2 which was resulting in picking a wrong
-primary channel.

-Subject: [PATCH] brcmfmac: analyze descriptors of current component only
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far we were looking for address descriptors without a check for
-crossing current component border. In case of dealing with unsupported
-descriptor or descriptor missing at all the code would incorrectly get
-data from another component.
-
-Consider this binary-described component from BCM4366 EROM:
-4bf83b01 TAG==CI CID==0x83b
-20080201 TAG==CI PORTS==0+1 WRAPPERS==0+1
-18400035 TAG==ADDR SZ_SZD TYPE_SLAVE
-00050000
-18107085 TAG==ADDR SZ_4K TYPE_SWRAP
-
-Driver was assigning invalid base address to this core:
-brcmfmac: [6 ] core 0x83b:32 base 0x18109000 wrap 0x18107000
-which came from totally different component defined in EROM:
-43b36701 TAG==CI CID==0x367
-00000201 TAG==CI PORTS==0+1 WRAPPERS==0+0
-18109005 TAG==ADDR SZ_4K TYPE_SLAVE
-
-This change will also allow us to support components without wrapper
-address in the future.

-Separated PMU core can be found in new devices and should be used for

-This core is one of exceptions that doesn't have or need wrapper address

-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Platform NVRAM (stored on a flash partition) has entries separated by a
-NULL (\0) char. Our parsing code switches from VALUE state to IDLE
-whenever it meets a NULL (\0). When that happens our IDLE handler should
-simply consume it and analyze whatever is placed ahead.

-This fixes harmless warnings spamming debugging output:

-Subject: [PATCH] brcmfmac: sdio: Increase the default timeouts a bit
-
-On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems
-the card responds very quickly most of the time, unfortunately during
-initialisation it sometimes seems to take just a bit over 2 seconds to
-respond.
-
-This results intialization failing with message like:
- brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52
- brcmf_bus_start: failed: -52
- brcmf_sdio_firmware_callback: dongle is not responding
-
-Increasing the timeout to allow for a bit more headroom allows the
-card to initialize reliably.
-
-A quick search online after diagnosing/fixing this showed that Google
-has a similar patch in their ChromeOS tree, so this doesn't seem
-specific to the board I'm using.

-Subject: [PATCH] mac80211: minstrel: Change expected throughput unit back to
- Kbps
-
-The change from cur_tp to the function
-minstrel_get_tp_avg/minstrel_ht_get_tp_avg changed the unit used for the
-current throughput. For example in minstrel_ht the correct
-conversion between them would be:
-
- mrs->cur_tp / 10 == minstrel_ht_get_tp_avg(..).
-
-This factor 10 must also be included in the calculation of
-minstrel_get_expected_throughput and minstrel_ht_get_expected_throughput to
-return values with the unit [Kbps] instead of [10Kbps]. Otherwise routing
-algorithms like B.A.T.M.A.N. V will make incorrect decision based on these
-values. Its kernel based implementation expects expected_throughput always
-to have the unit [Kbps] and not sometimes [10Kbps] and sometimes [Kbps].
-
-The same requirement has iw or olsrdv2's nl80211 based statistics module
-which retrieve the same data via NL80211_STA_INFO_TX_BITRATE.
-
-Cc: stable@vger.kernel.org

-Subject: [PATCH] brcmfmac: Increase nr of supported flowrings.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-New generation devices have firmware which has more than 256 flowrings.
-E.g. following debugging message comes from 14e4:4365 BCM4366:
-[ 194.606245] brcmfmac: brcmf_pcie_init_ringbuffers Nr of flowrings is 264
-
-At various code places (related to flowrings) we were using u8 which
-could lead to storing wrong number or infinite loops when indexing with
-this type. This issue was quite easy to spot in brcmf_flowring_detach
-where it led to infinite loop e.g. on failed initialization.
-
-This patch switches code to proper types and increases the maximum
-number of supported flowrings to 512.
-
-Originally this change was sent in September 2015, but back it was
-causing a regression on BCM43602 resulting in:
-Unable to handle kernel NULL pointer dereference at virtual address ...
-
-The reason for this regression was missing update (s/u8/u16) of struct
-brcmf_flowring_ring. This problem was handled in 9f64df9 ("brcmfmac: Fix
-bug in flowring management."). Starting with that it's safe to apply
-this original patch as it doesn't cause a regression anymore.
-
-This patch fixes an infinite loop on BCM4366 which is supported since
-4.4 so it makes sense to apply it to stable 4.4+.

-Subject: [PATCH] mac80211: minstrel_ht: set default tx aggregation timeout to
- 0
-
-The value 5000 was put here with the addition of the timeout field to
-ieee80211_start_tx_ba_session. It was originally added in mac80211 to
-save resources for drivers like iwlwifi, which only supports a limited
-number of concurrent aggregation sessions.
-
-Since iwlwifi does not use minstrel_ht and other drivers don't need
-this, 0 is a better default - especially since there have been
-recent reports of aggregation setup related issues reproduced with
-ath9k. This should improve stability without causing any adverse
-effects.

-Subject: [PATCH] mac80211: Fix Public Action frame RX in AP mode
-
-Public Action frames use special rules for how the BSSID field (Address
-3) is set. A wildcard BSSID is used in cases where the transmitter and
-recipient are not members of the same BSS. As such, we need to accept
-Public Action frames with wildcard BSSID.
-
-Commit db8e17324553 ("mac80211: ignore frames between TDLS peers when
-operating as AP") added a rule that drops Action frames to TDLS-peers
-based on an Action frame having different DA (Address 1) and BSSID
-(Address 3) values. This is not correct since it misses the possibility
-of BSSID being a wildcard BSSID in which case the Address 1 would not
-necessarily match.
-
-Fix this by allowing mac80211 to accept wildcard BSSID in an Action
-frame when in AP mode.

-Subject: [PATCH] mac80211: minstrel_ht: improve sample rate skip logic
-
-There were a few issues that were slowing down the process of finding
-the optimal rate, especially on devices with multi-rate retry
-limitations:
-
-When max_tp_rate[0] was slower than max_tp_rate[1], the code did not
-sample max_tp_rate[1], which would often allow it to switch places with
-max_tp_rate[0] (e.g. if only the first sampling attempts were bad, but the
-rate is otherwise good).
-
-Also, sample attempts of rates between max_tp_rate[0] and [1] were being
-ignored in this case, because the code only checked if the rate was
-slower than [1].
-
-Fix this by checking against the fastest / second fastest max_tp_rate
-instead of assuming a specific order between the two.
-
-In my tests this patch significantly reduces the time until minstrel_ht
-finds the optimal rate right after assoc

-Subject: [PATCH] brcmfmac: increase timeout for tx eapol
-
-When keys get set and updated this has to happen after eapol got
-transmitted (without key or old key) before the key can be updated.
-To make sure the order of sending eapol and configuring key is done
-correctly a timeout for tx of eapol is applied. This timeout is set
-to 50 msec, which is not always enough. Especially in AP mode and
-key updates the timeout may need to be much longer because client(s)
-can be in powersave. Increase the timeout from 50 to 950 msec.

-
-Currently ARP and ND (IPv6 Neigbor Discovery) offload get disabled
-on entering suspend. However when firmwares support the wowl_cap
-iovar then these offload routines can be kept enabled as they
-will work during WOWL as well.
