-Subject: [PATCH] ath9k: Switch to using mac80211 intermediate software
- queues.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This switches ath9k over to using the mac80211 intermediate software
-queueing mechanism for data packets. It removes the queueing inside the
-driver, except for the retry queue, and instead pulls from mac80211 when
-a packet is needed. The retry queue is used to store a packet that was
-pulled but can't be sent immediately.
-
-The old code path in ath_tx_start that would queue packets has been
-removed completely, as has the qlen limit tunables (since there's no
-longer a queue in the driver to limit).
-
-Based on Tim's original patch set, but reworked quite thoroughly.

-Subject: [PATCH] mac80211: add NEED_ALIGNED4_SKBS hw flag
-
-HW/driver should set NEED_ALIGNED4_SKBS flag in case
-require aligned skbs to four-byte boundaries.
-This affect only TX direction.
-
-Padding is added after ieee80211_hdr, before IV/LLC.
-
-Before we have to do memmove(hdrlen) twice in the
-dirver. Once before we pass this to HW and next
-in tx completion (to be sure monitor will report
-this tx frame correctly).
-
-With this patch we can skip this memmove() and save CPU.
-
-Currently this was tested with ath9k, both hw/sw crypt for
-wep/tkip/ccmp.

+
+HW/driver should set NEED_ALIGNED4_SKBS flag in case
+require aligned skbs to four-byte boundaries.
+This affect only TX direction.
+
+Padding is added after ieee80211_hdr, before IV/LLC.
+
+Before we have to do memmove(hdrlen) twice in the
+dirver. Once before we pass this to HW and next
+in tx completion (to be sure monitor will report
+this tx frame correctly).
+
+With this patch we can skip this memmove() and save CPU.
+
+Currently this was tested with ath9k, both hw/sw crypt for
+wep/tkip/ccmp.

-Subject: [PATCH] mac80211: Use rhltable instead of rhashtable
-
-mac80211 currently uses rhashtable with insecure_elasticity set
-to true. The latter is because of duplicate objects. What's
-more, mac80211 walks the rhashtable chains by hand which is broken
-as rhashtable may contain multiple tables due to resizing or
-rehashing.
-
-This patch fixes it by converting it to the newly added rhltable
-interface which is designed for use with duplicate objects.
-
-With rhltable a lookup returns a list of objects instead of a
-single one. This is then fed into the existing for_each_sta_info
-macro.
-
-This patch also deletes the sta_addr_hash function since rhashtable
-defaults to jhash.
-

+soon as it's dequeued from the tid for the first time. Ensure that
+double calls to ath_tx_addto_baw (e.g. on retransmission) don't cause

-Subject: [PATCH] mac80211: fix sequence number allocation regression
-
-The recent commit that moved around TX handlers dropped the sequence
-number allocation at the end of ieee80211_tx_dequeue and calls
-ieee80211_tx_h_sequence instead (for the non-fast-xmit case).
-However, it did not change the fast-xmit sequence allocation condition
-in ieee80211_xmit_fast_finish, which skipped seqno alloc if intermediate
-tx queues are being used.
-
-Drop the now obsolete condition.
-
-Fixes: bb42f2d13ffc ("mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue")

+The code currently relies on refcounting to disable IRQs from within the
+IRQ handler and re-enabling them again after the tasklet has run.
+
+However, due to race conditions sometimes the IRQ handler might be
+called twice, or the tasklet may not run at all (if interrupted in the
+middle of a reset).
+
+This can cause nasty imbalances in the irq-disable refcount which will
+get the driver permanently stuck until the entire radio has been stopped
+and started again (ath_reset will not recover from this).
+
+Instead of using this fragile logic, change the code to ensure that
+running the irq handler during tasklet processing is safe, and leave the
+refcount untouched.

+ rt2x00lib module
+
+As reported by Felix:
+
+Though protected by an ifdef, introducing an usb symbol dependency in
+the rt2x00lib module is a major inconvenience for distributions that
+package kernel modules split into individual packages.
+
+Get rid of this unnecessary dependency by calling the usb related
+function from a more suitable place.

-+* Qualcomm Atheros ath9k wireless devices
-+
-+This node provides properties for configuring the ath9k wireless device. The
-+node is expected to be specified as a child node of the PCI controller to
-+which the wireless chip is connected.
-+
-+Required properties:
-+- compatible: For PCI and PCIe devices this should be an identifier following
-+ the format as defined in "PCI Bus Binding to Open Firmware"
-+ Revision 2.1. One of the possible formats is "pciVVVV,DDDD"
-+ where VVVV is the PCI vendor ID and DDDD is PCI device ID.
-+ Typically QCA's PCI vendor ID 168c is used while the PCI device
-+ ID depends on the chipset - see the following (possibly
-+ incomplete) list:
-+ - 0023 for AR5416
-+ - 0024 for AR5418
-+ - 0027 for AR9160
-+ - 0029 for AR9220 and AR9223
-+ - 002a for AR9280 and AR9283
-+ - 002b for AR9285
-+ - 002c for AR2427
-+ - 002d for AR9227
-+ - 002e for AR9287
-+ - 0030 for AR9380, AR9381 and AR9382
-+ - 0032 for AR9485
-+ - 0033 for AR9580 and AR9590
-+ - 0034 for AR9462
-+ - 0036 for AR9565
-+ - 0037 for AR9485
-+- reg: Address and length of the register set for the device.
-+
-+Optional properties:
-+- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
-+ ath9k wireless chip (in this case the calibration /
-+ EEPROM data will be loaded from userspace using the
-+ kernel firmware loader).
-+- mac-address: See ethernet.txt in the parent directory
-+- local-mac-address: See ethernet.txt in the parent directory
-+
-+
-+In this example, the node is defined as child node of the PCI controller:
-+&pci0 {
-+ wifi@168c,002d {
-+ compatible = "pci168c,002d";
-+ reg = <0x7000 0 0 0 0x1000>;
-+ qca,no-eeprom;
-+ };

-Subject: [PATCH] ath10k: Fix soft lockup during firmware crash/hw-restart
-
-During firmware crash (or) user requested manual restart
-the system gets into a soft lock up state because of the
-below root cause.
-
-During user requested hardware restart / firmware crash
-the system goes into a soft lockup state as 'napi_synchronize'
-is called after 'napi_disable' (which sets 'NAPI_STATE_SCHED'
-bit) and it sleeps into infinite loop as it waits for
-'NAPI_STATE_SCHED' to be cleared. This condition is hit because
-'ath10k_hif_stop' is called twice as below (resulting in calling
-'napi_synchronize' after 'napi_disable')
-
-'ath10k_core_restart' -> 'ath10k_hif_stop' (ATH10K_STATE_ON) ->
--> 'ieee80211_restart_hw' -> 'ath10k_start' -> 'ath10k_halt' ->
-'ath10k_core_stop' -> 'ath10k_hif_stop' (ATH10K_STATE_RESTARTING)
-
-Fix this by calling 'ath10k_halt' in ath10k_core_restart itself
-as it makes more sense before informing mac80211 to restart h/w
-Also remove 'ath10k_halt' in ath10k_start for the state of 'restarting'
-

-Subject: [PATCH] cfg80211: limit scan results cache size
-
-It's possible to make scanning consume almost arbitrary amounts
-of memory, e.g. by sending beacon frames with random BSSIDs at
-high rates while somebody is scanning.
-
-Limit the number of BSS table entries we're willing to cache to
-1000, limiting maximum memory usage to maybe 4-5MB, but lower
-in practice - that would be the case for having both full-sized
-beacon and probe response frames for each entry; this seems not
-possible in practice, so a limit of 1000 entries will likely be
-closer to 0.5 MB.

-Subject: [PATCH] ath9k: Introduce airtime fairness scheduling between stations
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reworks the ath9k driver to schedule transmissions to connected
-stations in a way that enforces airtime fairness between them. It
-accomplishes this by measuring the time spent transmitting to or
-receiving from a station at TX and RX completion, and accounting this to
-a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based
-deficit scheduler is employed at packet dequeue time, to control which
-station gets the next transmission opportunity.
-
-Airtime fairness can significantly improve the efficiency of the network
-when station rates vary. The following throughput values are from a
-simple three-station test scenario, where two stations operate at the
-highest HT20 rate, and one station at the lowest, and the scheduler is
-employed at the access point:
-
- Before / After
-Fast station 1: 19.17 / 25.09 Mbps
-Fast station 2: 19.83 / 25.21 Mbps
-Slow station: 2.58 / 1.77 Mbps
-Total: 41.58 / 52.07 Mbps
-
-The benefit of airtime fairness goes up the more stations are present.
-In a 30-station test with one station artificially limited to 1 Mbps,
-we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This patch adds a helper for reading that new property and applying
-limitations of supported channels specified this way.
-It is used with devices that normally support a wide wireless band but
-in a given config are limited to some part of it (usually due to board
-design). For example a dual-band chipset may be able to support one band
-only because of used antennas.
-It's also common that tri-band routers have separated radios for lower
-and higher part of 5 GHz band and it may be impossible to say which is
-which without a DT info.

-
-ibss and mesh modes copy the ht capabilites from the band without
-overriding the SMPS state. Unfortunately the default value 0 for the
-SMPS field means static SMPS instead of disabled.
-
-This results in HT ibss and mesh setups using only single-stream rates,

-Subject: [PATCH] mac80211: initialize fast-xmit 'info' later
-
-In ieee80211_xmit_fast(), 'info' is initialized to point to the skb
-that's passed in, but that skb may later be replaced by a clone (if
-it was shared), leading to an invalid pointer.
-
-This can lead to use-after-free and also later crashes since the
-real SKB's info->hw_queue doesn't get initialized properly.
-
-Fix this by assigning info only later, when it's needed, after the
-skb replacement (may have) happened.

-On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag,
-we crash when the peer sends an AddBA request while we already

-drivers, the tid_agg_rx is left NULL even though the session is
-valid, and the agg_session_valid bit is set.
-
-To fix this, store the dialog tokens outside the tid_agg_rx to

-Subject: [PATCH] mac80211: prevent skb/txq mismatch
-
-Station structure is considered as not uploaded
-(to driver) until drv_sta_state() finishes. This
-call is however done after the structure is
-attached to mac80211 internal lists and hashes.
-This means mac80211 can lookup (and use) station
-structure before it is uploaded to a driver.
-
-If this happens (structure exists, but
-sta->uploaded is false) fast_tx path can still be
-taken. Deep in the fastpath call the sta->uploaded
-is checked against to derive "pubsta" argument for
-ieee80211_get_txq(). If sta->uploaded is false
-(and sta is actually non-NULL) ieee80211_get_txq()
-effectively downgraded to vif->txq.
-
-At first glance this may look innocent but coerces
-mac80211 into a state that is almost guaranteed
-(codel may drop offending skb) to crash because a
-station-oriented skb gets queued up on
-vif-oriented txq. The ieee80211_tx_dequeue() ends
-up looking at info->control.flags and tries to use
-txq->sta which in the fail case is NULL.
-
-It's probably pointless to pretend one can
-downgrade skb from sta-txq to vif-txq.
-
-Since downgrading unicast traffic to vif->txq must
-not be done there's no txq to put a frame on if
-sta->uploaded is false. Therefore the code is made
-to fall back to regular tx() op path if the
-described condition is hit.
-
-Only drivers using wake_tx_queue were affected.
-
-Example crash dump before fix:
-
- Unable to handle kernel paging request at virtual address ffffe26c
- PC is at ieee80211_tx_dequeue+0x204/0x690 [mac80211]

-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-A bugfix added a sanity check around the assignment and use of the
-'is_11d' variable, which looks correct to me, but as the function is
-rather complex already, this confuses the compiler to the point where
-it can no longer figure out if the variable is always initialized
-correctly:
-
-brcm80211/brcmfmac/cfg80211.c: In function ‘brcmf_cfg80211_start_ap’:
-brcm80211/brcmfmac/cfg80211.c:4586:10: error: ‘is_11d’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
-
-This adds an initialization for the newly introduced case in which
-the variable should not really be used, in order to make the warning
-go away.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far our core code was calling brcmf_fws_process_skb which wasn't
-a proper thing to do. If case of devices using msgbuf protocol fwsignal
-shouldn't be used. It was an unnecessary extra layer simply calling
-a protocol specifix txdata function.
-
-Please note we already have txdata callback, but it's used for calls
-between bcdc and fwsignal so it couldn't be simply used there.
-
-This makes core code more generic (instead of bcdc/fwsignal specific).

- stopped
-
-Firmware doesn't update beacon/Probe Response vendor IEs correctly when
-bss is down, so we move brcmf_config_ap_mgmt_ie after BSS up. And host
-driver should clear IEs when AP stopped so that the IEs in host side will
-be synced with in firmware side.

-Subject: [PATCH] ath9k: fix race condition in enabling/disabling IRQs
-
-The code currently relies on refcounting to disable IRQs from within the
-IRQ handler and re-enabling them again after the tasklet has run.
-
-However, due to race conditions sometimes the IRQ handler might be
-called twice, or the tasklet may not run at all (if interrupted in the
-middle of a reset).
-
-This can cause nasty imbalances in the irq-disable refcount which will
-get the driver permanently stuck until the entire radio has been stopped
-and started again (ath_reset will not recover from this).
-
-Instead of using this fragile logic, change the code to ensure that
-running the irq handler during tasklet processing is safe, and leave the
-refcount untouched.

-
-This chip was already supported, but seems a device came up giving
-a different chip identifier. So adding that effectively mapping to
-the same firmware file as for 43340 chip.

-
-The ssids list in the scheduled scan request were not properly taken
-into account when configuring in firmware. The hidden bit was set for
-any ssid resulting in active scanning for all. Only set it for ssids
-that are in the ssids list.

-Subject: [PATCH] brcmfmac: avoid writing channel out of allocated array
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Our code was assigning number of channels to the index variable by
-default. If firmware reported channel we didn't predict this would
-result in using that initial index value and writing out of array. This
-never happened so far (we got a complete list of supported channels) but
-it means possible memory corruption so we should handle it anyway.
-
-This patch simply detects unexpected channel and ignores it.
-
-As we don't try to create new entry now, it's also safe to drop hw_value
-and center_freq assignment. For known channels we have these set anyway.
-
-I decided to fix this issue by assigning NULL or a target channel to the
-channel variable. This was one of possible ways, I prefefred this one as
-it also avoids using channel[index] over and over.

-Subject: [PATCH] brcmfmac: setup wiphy bands after registering it first
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-During bands setup we disable all channels that firmware doesn't support
-in the current regulatory setup. If we do this before wiphy_register
-it will result in copying set flags (including IEEE80211_CHAN_DISABLED)
-to the orig_flags which is supposed to be persistent. We don't want this
-as regulatory change may result in enabling some channels. We shouldn't
-mess with orig_flags then (by changing them or ignoring them) so it's
-better to just take care of their proper values.
-
-This patch cleanups code a bit (by taking orig_flags more seriously) and
-allows further improvements like disabling really unavailable channels.
-We will need that e.g. if some frequencies should be disabled for good
-due to hardware setup (design).

-BCM43455 is a more recent revision of the BCM4345. Some of the BCM43455
-got a dedicated SDIO device ID which is currently not supported by
-brcmfmac.
-Adding the new sdio_device_id to brcmfmac is enough to get the BCM43455

-brcmf_sdio_fromevntchan() was being called on the the data frame

-mischaracterized as on the event channel rather than the data channel.
-
-This fixes a major performance regression (due to dropped packets). With

-Subject: [PATCH] brcmfmac: drop brcmf_bus_detach and inline its code
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Driver used to call brcmf_bus_detach only from one place and it already
-contained a check for drvr not being NULL. We can get rid of this extra
-function, call brcmf_bus_stop directly and simplify the code.
-There also isn't brcmf_bus_attach function which one could expect so it
-looks more consistent this way.

-Subject: [v2 PATCH 2/7] ath9k: indicate that the AR9003 EEPROM template values
- are little endian
-
-The eepMisc field was not set explicitly. The default value of 0 means
-that the values in the EEPROM (template) should be interpreted as little
-endian. However, this is not clear until comparing the AR9003 code with
-the other EEPROM formats.
-To make the code easier to understand we explicitly state that the values
-are little endian - there are no functional changes with this patch.

-This allows deciding if we have to swap the EEPROM data (so it matches
-the system's native endianness) even if no byte-swapping (swab16, based on
-the first two bytes in the EEPROM) is needed.

-get_eeprom(ah, EEP_MINOR_REV) and get_eeprom_rev(ah) are both doing the

-Subject: [v2 PATCH 5/7] ath9k: consistently use get_eeprom_rev(ah)
-
-The AR5416_VER_MASK macro does the same as get_eeprom_rev, except that
-one has to know the actual EEPROM type (and providing a reference to
-that in a variable named "eep"). Additionally the eeprom_*.c
-implementations used the same shifting logic multiple times to get the
-eeprom revision which was also unnecessary duplication of
-get_eeprom_rev.
-
-Also use the AR5416_EEP_VER_MINOR_MASK macro where needed and introduce
-a similar macro (AR5416_EEP_VER_MAJOR_MASK) for the major version.
-Finally drop AR9287_EEP_VER_MINOR_MASK since it simply duplicates the
-already defined AR5416_EEP_VER_MINOR_MASK.

-Subject: [v2 PATCH 6/7] ath9k: Make the EEPROM swapping check use the eepmisc
- register
-
-There are two ways of swapping the EEPROM data in the ath9k driver:
-1) swab16 based on the first two EEPROM "magic" bytes (same for all
- EEPROM formats)
-2) field and EEPROM format specific swab16/swab32 (different for
- eeprom_def, eeprom_4k and eeprom_9287)
-
-The result of the first check was used to also enable the second swap.
-This behavior seems incorrect, since the data may only be byte-swapped
-(afterwards the data could be in the correct endianness).
-Thus we introduce a separate check based on the "eepmisc" register
-(which is part of the EEPROM data). When bit 0 is set, then the EEPROM
-format specific values are in "big endian". This is also done by the
-FreeBSD kernel, see [0] for example.
-
-This allows us to parse EEPROMs with the "correct" magic bytes but
-swapped EEPROM format specific values. These EEPROMs (mostly found in
-lantiq and broadcom based big endian MIPS based devices) only worked
-due to platform specific "hacks" which swapped the EEPROM so the
-magic was inverted, which also enabled the format specific swapping.
-With this patch the old behavior is still supported, but neither
-recommended nor needed anymore.

-Subject: [v2 PATCH 7/7] ath9k: define all EEPROM fields in Little Endian format
-
-The ar9300_eeprom logic is already using only 8-bit (endian neutral),
-__le16 and __le32 fields to state explicitly how the values should be
-interpreted.
-All other EEPROM implementations (4k, 9287 and def) were using u16 and
-u32 fields with additional logic to swap the values (read from the
-original EEPROM) so they match the current CPUs endianness.
-
-The EEPROM format defaults to "all values are Little Endian", indicated
-by the absence of the AR5416_EEPMISC_BIG_ENDIAN in the u8 EEPMISC
-register. If we detect that the EEPROM indicates Big Endian mode
-(AR5416_EEPMISC_BIG_ENDIAN is set in the EEPMISC register) then we'll
-swap the values to convert them into Little Endian. This is done by
-activating the EEPMISC based logic in ath9k_hw_nvram_swap_data even if
-AH_NO_EEP_SWAP is set (this makes ath9k behave like the FreeBSD driver,
-which also does not have a flag to enable swapping based on the
-AR5416_EEPMISC_BIG_ENDIAN bit). Before this logic was only used to
-enable swapping when "current CPU endianness != EEPROM endianness".
-
-After changing all relevant fields to __le16 and __le32 sparse was used
-to check that all code which reads any of these fields uses
-le{16,32}_to_cpu.

-The shared memory of the rt2800 devices is accessible

-Subject: [PATCH] rt2x00: rt2800lib: fix beacon generation on RT3593
-
-On the RT3593 chipset, the beacon registers are located
-in the high 8KB part of the shared memory.
-
-The high part of the shared memory is only accessible
-if it is explicitly selected. Add a helper function
-in order to be able to control the SHR_MSEL bit in
-the PBF_SYS_CTRL register. Also add a few more helper
-functions and use those to select the correct part of
-the shared memory before and after accessing the beacon
-registers.
-
-The base addresses of the beacon registers are also
-different from the actually used values, so fix the
-'rt2800_hw_beacon_base' function to return the correct
-values.

- rt2800_drv_data
-
-Some chipsets can handle more than 8 beacons at once.
-Add a new field to the rt2800_drv_data structure which
-will hold the number of supported beacons of the given
-chipset.
-
-Update the rt2x00_init_registers function to get the
-beacon count from the new field instead of using a
-hardcoded value.
-
-In order to keep the current behaviour, initialize the
-new field with the actually used value.

-Subject: rt2x00: add support for mac addr from device tree
-
-On some devices the EEPROMs of Ralink Wi-Fi chips have a default Ralink
-MAC address set (RT3062F: 00:0C:43:30:62:00, RT3060F:
-00:0C:43:30:60:00). Using multiple of these devices in the same network
-can cause nasty issues.
-
-Allow to override the MAC in the EEPROM with (a known good) one set in
-the device tree to bypass the issue.

-
-The 8192eu suffered from two issues when reloading the driver.
-
-The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and
-23 didn't get set in rtl8192e_enable_rf().
-
-In addition it also seems prone to issues when setting REG_RF_CTRL to
-0 intead of just disabling the RF_ENABLE bit. Similar to what was
-causing issues with the 8188eu.
-
-With this patch I can successfully reload the driver and reassociate
-to an APi with an 8192eu dongle.

-Subject: [PATCH] rtl8xxxu: Pass tx_info to fill_txdesc in order to have access
- to retry count
-
-In order to obtain retry count for a given rate we need to pass the
-full struct ieee80211_tx_info to the function setting the rate in he
-TX descriptor.
-
-This uncovered a huge bug where the old code would use struct
-ieee80211_rate.flags to test for rate parameters, which is always
-zero, instead of the flags value from struct ieee80211_tx_rate.
-
-Time to find a brown paper bag :(
