+Date: Tue, 18 Nov 2014 23:58:51 +0100
+Subject: [PATCH] mac80211: add an intermediate software queue implementation
+
+This allows drivers to request per-vif and per-sta-tid queues from which
+they can pull frames. This makes it easier to keep the hardware queues
+short, and to improve fairness between clients and vifs.
+
+The task of scheduling packet transmission is left up to the driver -
+queueing is controlled by mac80211. Drivers can only dequeue packets by
+calling ieee80211_tx_dequeue. This makes it possible to add active queue
+management later without changing drivers using this code.
+
+This can also be used as a starting point to implement A-MSDU
+aggregation in a way that does not add artificially induced latency.
+
+Signed-off-by: Felix Fietkau <nbd@openwrt.org>

+Subject: [PATCH] mac80211: lock rate control
+
+Both minstrel (reported by Sven Eckelmann) and the iwlwifi rate
+control aren't properly taking concurrency into account. It's
+likely that the same is true for other rate control algorithms.
+
+In the case of minstrel this manifests itself in crashes when an
+update and other data access are run concurrently, for example
+when the stations change bandwidth or similar. In iwlwifi, this
+can cause firmware crashes.
+
+Since fixing all rate control algorithms will be very difficult,
+just provide locking for invocations. This protects the internal
+data structures the algorithms maintain.
+
+I've manipulated hostapd to test this, by having it change its
+advertised bandwidth roughly ever 150ms. At the same time, I'm
+running a flood ping between the client and the AP, which causes
+this race of update vs. get_rate/status to easily happen on the
+client. With this change, the system survives this test.

-Subject: [PATCH] ath9k: Fix RTC_DERIVED_CLK usage
-
-Based on the reference clock, which could be 25MHz or 40MHz,
-AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
-But, when a chip reset is done, processing the initvals
-sets the register back to the default value.
-
-Fix this by moving the code in ath9k_hw_init_pll() to
-ar9003_hw_override_ini(). Also, do this override for AR9531.

+Subject: [PATCH] ath5k: channel change fix
+
+ath5k updates the channel pointer and after that it stops the Rx logic
+and apply channel to HW. In case of channel switch, such sequence
+creates a small window when a frame, which is received on the old
+channel is considered as a frame received on the new one.
+
+The most notable consequence of this situation occurs during the switch
+from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
+with CCK rate, e.g. beacon received at the 1mbps, causes the following
+warning:
+

+
+The easiest way to reproduce this warning is to run scan with dualband
+NIC in noisy environments, when the channel 11 runs multiple APs. In my
+tests if the APs num >= 12, the warning appears in the first few
+seconds of scanning.
+
+In order to fix this, the Rx disable code moved to a higher level and
+placed before the channel pointer update. This is also makes the code a
+bit more symmetrical, since we disable and enable the Rx in the same
+function.
+
+In fact, at the pointer update time new frames should not appear,
+because interrupt generation at this point should already be disabled.
+The next patch should address this issue.

+Subject: [PATCH] ath5k: fix reset race
+
+To prepare for reset ath5k should finish all asynchronous tasks. At
+first, it disables the interrupt generation, then it waits for the
+interrupt handler and tasklets completion, and then proceeds to the HW
+configuration update. But it does not consider that the interrupt
+handler or tasklet re-enables the interrupt generation. And we fall in a
+situation when ath5k assumes that interrupts are disabled, but it is
+not.
+
+This can lead to different consequences, such as reception of the frame,
+when we do not expect it. Under certain circumstances, this can lead to
+the following warning:
+
+ WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]()

+
+Fix this issue by adding a new status flag, which forbids to re-enable

+Note: previous patch, which reorders the Rx disable code helps to avoid
+the above warning, but not fixes the root cause of unexpected frame
+receiving.

-
- ath9k: Summarize hw state per channel context

-
-broke multi-vif configuration due to not properly calculating
-the bssid mask.
-
-The test case that caught this was:
-
- create wlan0 and sta0-4 (6 total), not sure how much that matters.
- associate all 6 (works fine)
- disconnect 5 of them, leaving sta0 up
- Start trying to bring up the other 5 one at a time. It will
- fail, with iw events looking like this (in these logs, several
- sta are trying to come up, but symptom is the same with just one)
-
-The patch causing the regression made quite a few changes, but
-the part I think caused this particular problem was not
-recalculating the bssid mask when adding and removing interfaces.
-
-Re-adding those calls fixes my test case. Fix bad comment
-as well.

-Subject: [PATCH] mac80211: minstrel_ht: fix a crash in rate sorting
-
-The commit 5935839ad73583781b8bbe8d91412f6826e218a4
-"mac80211: improve minstrel_ht rate sorting by throughput & probability"
-
-introduced a crash on rate sorting that occurs when the rate added to
-the sorting array is faster than all the previous rates. Due to an
-off-by-one error, it reads the rate index from tp_list[-1], which
-contains uninitialized stack garbage, and then uses the resulting index
-for accessing the group rate stats, leading to a crash if the garbage
-value is big enough.

-Subject: [PATCH] mac80211: add an intermediate software queue implementation
-
-This allows drivers to request per-vif and per-sta-tid queues from which
-they can pull frames. This makes it easier to keep the hardware queues
-short, and to improve fairness between clients and vifs.
-
-The task of scheduling packet transmission is left up to the driver -
-queueing is controlled by mac80211. Drivers can only dequeue packets by
-calling ieee80211_tx_dequeue. This makes it possible to add active queue
-management later without changing drivers using this code.
-
-This can also be used as a starting point to implement A-MSDU
-aggregation in a way that does not add artificially induced latency.

- reset
-
-To fix invalid hardware accesses, the commit
-"ath9k: do not access hardware on IRQs during reset" made the irq
-handler ignore interrupts emitted after queueing a hardware reset (which
-disables the IRQ). This left a small time window for the IRQ to get
-re-enabled by the tasklet, which caused IRQ storms.
-Instead of returning IRQ_NONE when ATH_OP_HW_RESET is set, disable the
-IRQ entirely for the duration of the reset.

-Subject: [PATCH] ath5k: fix spontaneus AR5312 freezes
-
-Sometimes while CPU have some load and ath5k doing the wireless
-interface reset the whole WiSoC completely freezes. Set of tests shows
-that using atomic delay function while we wait interface reset helps to
-avoid such freezes.
-
-The easiest way to reproduce this issue: create a station interface,
-start continous scan with wpa_supplicant and load CPU by something. Or
-just create multiple station interfaces and put them all in continous
-scan.
-
-This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use
-usleep_range where possible"), which replaces initial udelay()
-by usleep_range().
-
-I do not know actual source of this issue, but all looks like that HW
-freeze is caused by transaction on internal SoC bus, while wireless
-block is in reset state.
-
-Also I should note that I do not know how many chips are affected, but I
-did not see this issue with chips, other than AR5312.

-Subject: [PATCH] ath5k: channel change fix
-
-ath5k updates the channel pointer and after that it stops the Rx logic
-and apply channel to HW. In case of channel switch, such sequence
-creates a small window when a frame, which is received on the old
-channel is considered as a frame received on the new one.
-
-The most notable consequence of this situation occurs during the switch
-from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
-with CCK rate, e.g. beacon received at the 1mbps, causes the following
-warning:

-The easiest way to reproduce this warning is to run scan with dualband
-NIC in noisy environments, when the channel 11 runs multiple APs. In my
-tests if the APs num >= 12, the warning appears in the first few
-seconds of scanning.
-
-In order to fix this, the Rx disable code moved to a higher level and
-placed before the channel pointer update. This is also makes the code a
-bit more symmetrical, since we disable and enable the Rx in the same
-function.
-
-In fact, at the pointer update time new frames should not appear,
-because interrupt generation at this point should already be disabled.
-The next patch should address this issue.

-Subject: [PATCH] ath5k: fix reset race
-
-To prepare for reset ath5k should finish all asynchronous tasks. At
-first, it disables the interrupt generation, then it waits for the
-interrupt handler and tasklets completion, and then proceeds to the HW
-configuration update. But it does not consider that the interrupt
-handler or tasklet re-enables the interrupt generation. And we fall in a
-situation when ath5k assumes that interrupts are disabled, but it is
-not.
-
-This can lead to different consequences, such as reception of the frame,
-when we do not expect it. Under certain circumstances, this can lead to
-the following warning:
-
- WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]()
- invalid hw_rix: 1a

- [<800418a8>] ret_from_kernel_thread+0x14/0x1c
-
-Fix this issue by adding a new status flag, which forbids to re-enable
-the interrupt generation until the HW configuration is completed.
-
-Note: previous patch, which reorders the Rx disable code helps to avoid
-the above warning, but not fixes the root cause of unexpected frame
-receiving.
