This patch fixes two problems with the minstrel_ht rate control algorithms handling of A-MPDU frames: 1. The ampdu_len field of the tx status is not always initialized for non-HT frames (and it would probably be unreasonable to require all drivers to do so). This could cause rate control statistics to be corrupted. We now trust the ampdu_len and ampdu_ack_len fields only when the frame is marked with the IEEE80211_TX_STAT_AMPDU flag. 2. Successful transmission attempts where only recognized when the A-MPDU subframe carrying the rate control status information was marked with the IEEE80211_TX_STAT_ACK flag. If this information happed to be carried on a frame that failed to be ACKed then the other subframes (which may have succeeded) where not correctly registered. We now update rate control statistics regardless of whether the subframe carrying the information was ACKed or not. Cc: <stable@kernel.org> Signed-off-by:

Since this small buffer isn't used for DMA, we can simply allocate it on the stack, it just needs to be 16 bytes of which only 8 will be used for WEP40 keys. Signed-off-by:

wl1271 driver is under heavy development but on the other hand the older wl1251 driver is currently considered more as a legacy driver. To make it easier to develop wl1271 features move wl1251 to it's own directory, drivers/net/wireless/wl1251. There are no functional changes, only moving of files. One regression is that Kconfig won't be updated automatically and user needs to enable wl1251 manually with an older config file. Signed-off-by:

In preparation of moving wl1251 out from drivers/net/wireless/wl12xx create a separate copy of wl12xx_80211.h. This file should not even exist, we should instead use generic ieee80211 definitions. This will be fixed in the future so that the file can be removed. Signed-off-by:

In the past, carl9170 has been plagued by mysterious ghosts. e.g.: wlan4: deauthenticated from 02:04:d8:3c:ac:c1 (Reason: 0) Apparently, the AP sent us a bogus deauthentication notification. But upon closer inspection the "management frame" turned out to be a corrupted scrap of an unsuccessful A-MPDU. Signed-off-by:

The total/fatal error bit was erroneously prefixed with AR9170_RX_ERROR instead of AR9170_RX_STATUS. Luckily, the hardware specification confirmed that the 0x80 flag will never be set for mac->error. So, it was always just a dead branch. This patch also imports the latest version of shared wlan.h header from the firmware git. Signed-off-by:

The patches "rt2x00: Improve TX status entry validation" and "rt2x00: rework tx status handling in rt2800pci" together were causing problems with tx status processing in rt2800pci: phy1 -> rt2800pci_txdone: Warning - Got TX status for an empty queue 3, dropping phy1 -> rt2800pci_txdone: Warning - Got TX status for an unavailable queue 7, dropping Fix this by using the correct field definition for getting the QID out of the tx status report.

This patch updates IEEE802.11 mesh constants to be consistent with newly approved values. It modifies some values, as well as adds many new constants in preparation for updating mesh code to the current 802.11s drafts. ANA numbers were taken from: https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls A few notes are in order: 1. This will break backwards compatibility with existing Linux kernels as over-the-air constants have changed. 2. Some old and obsolete constants have been retained for now as the mesh code itself hasn't been updated yet to the new 802.11s draft. This was desired to keep the existing mesh scheme working until it can be updated. Adding the approved values is the first step in updating the mesh code. 3. Obsolete constants have been clearly marked. 4. All ANA approved 802.11s constants have been added. Signed-off-by:

Results for the active channel are updated whenever a new survey dump is requested, the old data is kept to allow multiple processes to make their own channel utilization averages. All other channels only contain the data for the last time that the hardware was on the channel, i.e. the last scan result or other off-channel activity. Running a background scan does not clear the data for the active channel. Signed-off-by:

Several serve threading problems in the current release reorder timer implementation have been discovered. A lengthy discussion - which lists some of the pitfalls and possible solutions - can be found at: http://marc.info/?t=128635927000001 But due to the complicated nature of the subject and the imminent advent of a new -rc cycle, it was decided to disable the feature for the time being.

This patch not only fixes a null-pointer de-reference that would be triggered by a PLINK_OPEN frame with mis- matching/incompatible mesh configuration, but also responds correctly to non-compatible PLINK_OPEN frames by generating a PLINK_CLOSE with the right reason code. The original bug was detected by smatch. ( http://repo.or.cz/w/smatch.git ) net/mac80211/mesh_plink.c +574 mesh_rx_plink_frame(168) error: we previously assumed 'sta' could be null.

This reverts commit 5a254ffe. The commit failed to take into account that allocated wireless devices (wiphys) are not added into the device list upon allocation, but only when they are registered. Therefore, it opened up a race between allocating and registering a name, so that if two processes allocate and register concurrently ("alloc, alloc, register, register" rather than "alloc, register, alloc, register") the code will attempt to use the same name twice.

Enable runtime PM for the wl1271 SDIO device. We request power whenever the WLAN interface is brought up, and release it after the WLAN interface is taken down. As a result, power is released immediately after probe returns, since at that point power has not been explicitly requested yet (i.e. the WLAN interface is still down). Signed-off-by:

6000g2 devices need to have temperature offset calibration. The runtime uCode needs to receive the calibration results just like BB and LO calibration. To do this, driver reads the offset value from NVM and send it to uCode after runtime uCode is alive. Signed-off-by:

iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as the chain noise reset calibration index and IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain calibration index, if not specified by the TLV value in the new firmware format. However, this is broken if we need to add more calibrations like the temperature offset calibration because we increased IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1. To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE and use it as the calibration index instead. We still keep the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for the TLV value given by ucode. Signed-off-by:

The set_pwr_src operation is only ever used from within the same sub-driver that it is declared in, so it can just be called directly instead of being an operation. Also, it is never called to set the power source to V_aux, so change the two functions accordingly (but keep the V_aux code for documentation purposes in a comment). Signed-off-by:
