2015-09-29mac80211: use bool argument to ieee80211_send_nullfuncJohannes Berg

2015-09-29mac80211: fix tx sequence number assignment with software queue + fast-xmitFelix Fietkau

2015-09-29mac80211: advertise support for full station state in AP modeAyala Beker
This enables adding stations in unauthenticated mode, just after receiving the first authentication frame; which in turn allows sending a negative authentication reply if the station cannot be added. In addition init rate control for unassociated station only when it becomes associated, prior to that low rates will be used.

2015-09-29cfg80211: allow changing station capabilities for unassociated stationsAyala Beker
Currently, cfg80211 rejects capability updates for existing entries and as a result it's impossible to update entries that were added unassociated, but that is necessary to go through the full station states from userspace, adding a station before authentication etc. Fix this by allowing updates to capabilities for stations that the driver (or mac80211) assigned unassociated state. Drivers setting the full station state support flag must use the new station type for proper operation.

2015-09-29mac80211: allow writing TX PN in debugfsJohannes Berg
For certain tests, for example replay detection, it can be useful to be able to influence/set the PN used in outgoing packets. Make it possible to change the TX PN in debugfs. For now, this doesn't support TKIP since I haven't needed it, but there's no reason it couldn't be added if necessary. Note that this must be used very carefully: it could, for example, be used to make "valid replays" where the PN reuse happens on a different TID. This couldn't be done by an attacker since the TID is protected as part of the AAD. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-09-29mac80211: don't tear down aggregation on suspend in case of wowlan->anyEliad Peller
In case of "any" wowlan trigger, there is no reason to tear down aggregations, as we want the device to continue working normally. Similarly, there's no reason to tear down aggregations on resume, as they should have been torn down on suspend if needed. However, since the reconfiguration flow is shared with HW restart, tear down aggregations on reconfiguration when we are not resuming. To keep things working after non-wowlan suspend, keep clearing the WLAN_STA_BLOCK_BA flag.

2015-09-29mac80211: Copy tx'ed beacons to monitor modeHelmut Schaa
When debugging wireless powersave issues on the AP side it's quite helpful to see our own beacons that are transmitted by the hardware/driver. However, this is not that easy since beacons don't pass through the regular TX queues. Preferably drivers would call ieee80211_tx_status also for tx'ed beacons but that's not always possible. Hence, just send a copy of each beacon generated by ieee80211_beacon_get_tim to monitor devices when they are getting fetched by the driver. Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by drivers to indicate that they report TX status for beacons.

2015-09-29mmc: pxamci: fix card detect with slot-gpio APIRobert Jarzmik
Move pxamci to mmc slot-gpio API to fix interrupt request. It fixes the case where the card detection is on a gpio expander, on I2C for example on zylonite board. In this case, the card detect netsted interrupt is called from a threaded interrupt. The request_irq() fails, because a hard irq cannot be a nested interrupt from a threaded interrupt (set __setup_irq()). This was tested on zylonite and mioa701 boards.

2015-09-29mmc: sunxi: Fix clk-delay settingsHans de Goede
In recent allwinner kernel sources the mmc clk-delay settings have been slightly tweaked, and for sun9i they are completely different then what we are using. This commit brings us in sync with what allwinner does, fixing problems accessing sdcards on some A33 devices (and likely others). For pre sun9i hardware this makes the following changes: -At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk) -At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk) This also drops the clk-delay calculation for clocks > 50 MHz, we do not need this as we've: mmc->f_max = 50000000, and the delays in the old code were not correct (at 100 MHz the delay must be a multiple of 60, at 200 MHz a multiple of 120).

Typically this means that the mmc host driver fails to probe. As the CD/WP GPIOs are already treated as optional, let's extend that to cover the case when CONFIG_GPIOLIB is unset.

2015-09-29mwifiex: fix mwifiex_rdeeprom_read()Dan Carpenter
There were several bugs here. 1) The done label was in the wrong place so we didn't copy any information out when there was no command given. 2) We were using PAGE_SIZE as the size of the buffer instead of "PAGE_SIZE - pos". 3) snprintf() returns the number of characters that would have been printed if there were enough space. If there was not enough space (and we had fixed the memory corruption bug #2) then it would result in an information leak when we do simple_read_from_buffer(). I've changed it to use scnprintf() instead. I also removed the initialization at the start of the function, because I thought it made the code a little more clear.

When p2p device interface gets deleted by deinitialising discovery it will result in an event which removes the interface, but that is also done by delete p2p interface code. This results in race condition which sometimes results in lockup/crash. With this patch the delete device interface will wait for the event (with timeout) removing the possible race condition.

For debugging purpose it is very handy to be able to disable features. It has happened a few times that new features turned out not always being properly detected for all devices/firmwares. Making it possible to disable the feature with a module parameter will make testing/debugging easier.

2015-09-29brcmfmac: Inform p2p module about p2pon through APIHante Meuleman
When the p2pon module param is used then p2p attach will initialize p2p device iface in the firmware, but it is doing that by checking data. It is cleaner to pass the p2pon information to p2p by API. This information is also needed for other patch.
