2014-07-23ath9k: fix aggregation session lockupFelix Fietkau
If an aggregation session fails, frames still end up in the driver queue with IEEE80211_TX_CTL_AMPDU set. This causes tx for the affected station/tid to stall, since ath_tx_get_tid_subframe returning packets to send. Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation session is running.

2014-07-07rt2800usb: Don't perform DMA from stackAndrea Merello
Function rt2800usb_autorun_detect() passes the address of a variable allocated onto the stack to be used for DMA by the USB layer. This has been caught by my debugging-enabled kernel. This patch change things in order to allocate that variable via kmalloc, and it adjusts things to handle the kmalloc failure case, propagating the error.

2014-06-25mwifiex: fix Tx timeout issueAmitkumar Karwar
https://bugzilla.kernel.org/show_bug.cgi?id=70191 https://bugzilla.kernel.org/show_bug.cgi?id=77581 It is observed that sometimes Tx packet is downloaded without adding driver's txpd header. This results in firmware parsing garbage data as packet length. Sometimes firmware is unable to read the packet if length comes out as invalid. This stops further traffic and timeout occurs. The root cause is uninitialized fields in tx_info(skb->cb) of packet used to get garbage values. In this case if MWIFIEX_BUF_FLAG_REQUEUED_PKT flag is mistakenly set, txpd header was skipped. This patch makes sure that tx_info is correctly initialized to fix the problem.

2014-06-17rt2x00: fix rfkill regression on rt2500pciStanislaw Gruszka
As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit.

2014-06-16mwifiex: fix tx_info/rx_info overlap with PCIe dma_mappingChin-Ran Lo
On PCIe Tx data path, network interface specific tx_info parameters such as bss_num and bss_type are saved at "skb->cb + sizeof(dma_addr_t)" (returned by MWIFIEX_SKB_TXCB). Later mwifiex_map_pci_memory() called from mwifiex_pcie_send_data() will memcpy sizeof(struct mwifiex_dma_mapping) bytes to save PCIe DMA address and length information at beginning of skb->cb. This accidently overwrites bss_num and bss_type saved in skb->cb previously because bss_num/bss_type and mwifiex_dma_mapping data overlap. Similarly, on PCIe Rx data path, rx_info parameters overlaps with PCIe DMA address and length information too. Fix it by defining mwifiex_cb structure and having MWIFIEX_SKB_TXCB and MWIFIEX_SKB_RXCB return the correct address of tx_info/rx_info using the structure members. Also add a BUILD_BUG_ON to maks sure that mwifiex_cb structure doesn't exceed the size of skb->cb.

2014-06-05at76c50x: fix scan does not work with latest mac80211Andrea Merello
since commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 scan in not working anymore, due to mac80211 requires rx frequency status information. This patch makes the driver report this information. While NOT scanning this is straightforward. While scanning the firmware performs RF sweep and we cannot track the actual tuning frequency, so this is guessed by parsing beacons and probe responses. This should be enough for ensuring functionality.

2014-06-02ath10k: fix 8th virtual AP interface with DFSBartosz Markowski
Firmware 10.x supports up to 8 virtual AP interfaces, but in a DFS channel it was possible to create only 7 interfaces as ath10k internal creates a monitor interface for DFS. Previous vdev map initialization was missing enough space for 8 + 1 vdevs due to wrong define used and that's why there was no space for 8th interface. Use the correct define TARGET_10X_NUM_VDEVS with 10.x firmware to make it possible to create the 8th virtual interface.

2014-06-02ath10k: remove unnecessary htt rx corruption checkMichal Kazior
While fixing a bug reported by Avery I went ahead and added a warning suspecting there might be something more to the bug. This ended up with people reporting they see warnings during heavy traffic. This bought me some time and helped me understand the problem better - apparently fw/hw can report a chained msdus as follows: 1 msdu, 1 chained, 1 msdu (0 length). The patch removes the extra check but leaves the other change that fixed the original skb_push panic bug (msdu_chaining was overwritten in an unfortunate way which made the above example to be treated as non-chained case).
