2012-02-03ath9k: Fix kernel panic during driver initilizationMohammed Shafi Shajakhan
all works need to be initialized before ieee80211_register_hw to prevent mac80211 call backs such as drv_start, drv_config getting started. otherwise we would queue/cancel works before initializing them and it leads to kernel panic. this issue can be recreated with the following script in Chrome laptops with AR928X cards, with background scan running (or) Network manager is running while true do sudo modprobe -v ath9k sleep 3 sudo modprobe -r ath9k sleep 3 done EIP: [<81040a47>] __cancel_work_timer+0xb8/0xe1 SS:ESP 0068:f6be9d70 ---[ end trace 4f86d6139a9900ef ]--- Registered led device: ath9k-phy0 ieee80211 phy0: Atheros AR9280 Rev:2 mem=0xf88a0000, irq=16 Kernel panic - not syncing: Fatal exception Pid: 456, comm: wpa_supplicant Tainted: G D 3.0.13 #1 Call Trace: [<81379e21>] panic+0x53/0x14a [<81004a30>] oops_end+0x73/0x81 [<81004b53>] die+0x4c/0x55 [<81002710>] do_trap+0x7c/0x83 [<81002855>] ? do_bounds+0x58/0x58 [<810028cc>] do_invalid_op+0x77/0x81 [<81040a47>] ? __cancel_work_timer+0xb8/0xe1 [<810489ec>] ? sched_clock_cpu+0x81/0x11f [<8103f809>] ? wait_on_work+0xe2/0xf7 [<8137f807>] error_code+0x67/0x6c [<810300d8>] ? wait_consider_task+0x4ba/0x84c [<81040a47>] ? __cancel_work_timer+0xb8/0xe1 [<810380c9>] ? try_to_del_timer_sync+0x5f/0x67 [<81040a91>] cancel_work_sync+0xf/0x11 [<f88d7b7c>] ath_set_channel+0x62/0x25c [ath9k] [<f88d67d1>] ? ath9k_tx_last_beacon+0x26a/0x85c [ath9k] [<f88d8899>] ath_radio_disable+0x3f1/0x68e [ath9k] [<f90d0edb>] ieee80211_hw_config+0x111/0x116 [mac80211] [<f90dd95c>] __ieee80211_recalc_idle+0x919/0xa37 [mac80211] [<f90dda76>] __ieee80211_recalc_idle+0xa33/0xa37 [mac80211] [<812dbed8>] __dev_open+0x82/0xab Cc: <stable@vger.kernel.org> Cc: Gary Morain <gmorain@google.com> Cc: Paul Stewart <pstew@google.com> Cc: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Tested-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

2012-02-03mwifiex: handle association failure case correctlyAmitkumar Karwar
Currently even if association is failed "iw link" shows some information about connected BSS and "Tx timeout" error is seen in dmesg log. This patch fixes below issues in the code to handle assoc failure case correctly. 1) "status" variable in mwifiex_wait_queue_complete() is not correctly updated. Hence driver doesn't inform cfg80211 stack about association failure. 2) During association network queues are stopped but carrier is not cleared, which gives Tx timeout error in failure case Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2012-02-03ixgbevf: Fix mailbox interrupt ack bugGreg Rose
Remove jump to out label that was skipping over code to replace the ack bit in the mailbox cache variable. This was causing driver mailbox routines that poll for the PF to ack a message to time out which would in turn cause all other mailbox messages to fail. Also replace the mailbox cache variable message indication bit when a message is found so that other functions that choose to poll for a mailbox message from the PF won't miss it.

2012-02-03can: flexcan: Fix CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACKReuben Dowle
Currently the flexcan driver uses hardware local echo. This blindly echos all transmitted frames to all receiving sockets, regardless what CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to. This patch now submits transmitted frames to be echoed in the transmit complete interrupt, preserving the reference to the sending socket. This allows the can protocol to correctly handle the local echo. Further this patch moves tx_bytes statistic accounting into the tx_complete handler.

2012-02-03can: flexcan: fix irq flooding by clearing all interrupt sourcesWolfgang Grandegger
As pointed out by Reuben Dowle and Lothar Waßmann, the TWRN_INT, RWRN_INT, BOFF_INT interrupt sources need to be cleared as well to avoid interrupt flooding, at least for the Flexcan on i.MX28 SOCs. Furthermore, the interrupts are only cleared, if really one of those interrupt sources are pending (which is not the case for rx and tx done).
