2011-11-17p54spi: Fix workqueue deadlockMichael Büsch
priv->work must not be synced while priv->mutex is locked, because the mutex is taken in the work handler. Move cancel_work_sync down to after the device shutdown code. This is safe, because the work handler checks fw_state and bails out early in case of a race.

2011-11-17rt2x00: handle spurious pci interruptsStanislaw Gruszka
We have documented case of very bad performance issue on rt2800pci device, because it generate spurious interrupt, what cause irq line is disabled: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We already address that problem in separate patch by returning IRQ_HANDLED from interrupt handler. We think similar fix is needed for other rt2x00 PCI devices, because users report performance problems on these devices too.

2011-11-15rt2x00: Fix sleep-while-atomic bug in powersaving code.Gertjan van Wingerde
The generic powersaving code that determines after reception of a frame whether the device should go back to sleep or whether is could stay awake was calling rt2x00lib_config directly from RX tasklet context. On a number of the devices this call can actually sleep, due to having to confirm that the sleeping commands have been executed successfully. Fix this by moving the call to rt2x00lib_config to a workqueue call.

2011-11-11mwifiex: fix association issue with AP configured in hidden SSID modeAmitkumar Karwar
Firmware expects 'max_ssid_length' field in 'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for performing SSID specific scan. Currently driver updates it with an actual SSID length. Hence UUT is not able to find the AP configured in hidden SSID mode in scan results and association fails. max_ssid_length is filled with '0' to fix the issue.

2011-11-11iwlwifi: avoid a panic when unloading the module with RF KillEmmanuel Grumbach
When HW RF kill switch is set to kill the radio, our NIC issues an interrupt after we stop the APM module. When we unload the module, the driver disables and cleans the interrupts before stopping the APM. So we have a real interrupt (inta not zero) pending. When this interrupts pops up the tasklet has already been killed and we crash. Here is a logical description of the flow: disable and clean interrupts synchronize interrupts kill the tasklet stop the APM <<== creates an RF kill interrupt free_irq <<== somehow our ISR is called here and we crash Here is the panic message: [ 201.313636] BUG: unable to handle kernel paging request at ffff8800911b7150 [ 201.314541] IP: [<ffffffff8106d652>] tasklet_action+0x62/0x130 [ 201.315149] PGD 1c06063 PUD db37f067 PMD db408067 PTE 80000000911b7160 [ 201.316456] Oops: 0000 [#1] SMP DEBUG_PAGEALLOC [ 201.317324] CPU 1 [ 201.317495] Modules linked in: arc4 iwlwifi(-) mac80211 cfg80211 netconsole configfs binfmt_misc i915 drm_kms_helper drm uvcvideo i2c_algo_bit videodev dell_laptop dcdbas intel_agp dell_wmi intel_ips psmouse intel_gtt v4l2_compat_ioctl32 asix usbnet mii serio_raw video sparse_keymap firewire_ohci sdhci_pci sdhci firewire_core e1000e crc_itu_t [last unloaded: configfs] [ 201.323839] [ 201.324015] Pid: 2061, comm: modprobe Not tainted 3.1.0-rc9-wl #4 Dell Inc.

2011-11-02libertas: ensure we clean up a scan request properlyAndres Salomon
Commit 2e30168b ("libertas: terminate scan when stopping interface") adds cleanup code to lbs_eth_stop to call cfg80211_scan_done if there's an outstanding cfg80211_scan_request. However, it assumes that the scan request was allocated via the cfg80211 stack. Libertas has its own internal allocation method, kept track of with priv->internal_scan. This doesn't set scan_req->wiphy, amongst other things, which results in hitting a BUG() when we call cfg80211_scan_done on the request. This provides a function to take care of the low-level scan_req cleanup details. We simply call that to deal with finishing up scan requests. The bug we were hitting was: [ 964.321495] kernel BUG at net/wireless/core.h:87!

Previously the driver did not care if TX_CTL_REQ_TX_STATUS was set on aggregated frames or not and it would silently drop successfully sent frames if possible [much like: "no news is good news!"]. But, TX_CTL_REQ_TX_STATUS was invented for a reason and no tx status report should ever be dropped if it is set.

2011-10-31Bluetooth: bfusb: Fix error path on firmware loadDavid Herrmann
When loading the usb-configuration we do not signal the end of configuration on memory allocation error. This patch moves the memory allocation to the top so every error path uses "goto error" now to correctly send the usb-ctrl message when detecting some error. This also replaces GFP_ATOMIC with GFP_KERNEL as we are allowed to sleep here.

2011-10-31Bluetooth: bcm203x: Fix race condition on disconnectDavid Herrmann
When disconnecting a bcm203x device we kill and destroy the usb-urb, however, there might still be a pending work-structure which resubmits the now invalid urb. To avoid this race condition, we simply set a shutdown-flag and synchronously kill the worker first. This also adds a comment to all schedule_work()s, as it is really not clear that they are used as replacement for short timers (which can be seen in the git history).

2011-10-30bonding: eliminate bond_close race conditionsJay Vosburgh
This patch resolves two sets of race conditions. Mitsuo Hayasaka <mitsuo.hayasaka.hu@hitachi.com> reported the first, as follows: The bond_close() calls cancel_delayed_work() to cancel delayed works. It, however, cannot cancel works that were already queued in workqueue. The bond_open() initializes work->data, and proccess_one_work() refers get_work_cwq(work)->wq->flags. The get_work_cwq() returns NULL when work->data has been initialized. Thus, a panic occurs. He included a patch that converted the cancel_delayed_work calls in bond_close to flush_delayed_work_sync, which eliminated the above problem. His patch is incorporated, at least in principle, into this patch. In this patch, we use cancel_delayed_work_sync in place of flush_delayed_work_sync, and also convert bond_uninit in addition to bond_close. This conversion to _sync, however, opens new races between bond_close and three periodically executing workqueue functions: bond_mii_monitor, bond_alb_monitor and bond_activebackup_arp_mon. The race occurs because bond_close and bond_uninit are always called with RTNL held, and these workqueue functions may acquire RTNL to perform failover-related activities. If bond_close or bond_uninit is waiting in cancel_delayed_work_sync, deadlock occurs. These deadlocks are resolved by having the workqueue functions acquire RTNL conditionally. If the rtnl_trylock() fails, the functions reschedule and return immediately. For the cases that are attempting to perform link failover, a delay of 1 is used; for the other cases, the normal interval is used (as those activities are not as time critical). Additionally, the bond_mii_monitor function now stores the delay in a variable (mimicing the structure of activebackup_arp_mon). Lastly, all of the above renders the kill_timers sentinel moot, and therefore it has been removed.

Instead, just checking for RESETTING_BIT not set before sending config_led command down to card. o Take rtnl_lock instead of RESETTING_BIT for beacon test while sending config_led command down to make sure interface cannot be brought up/ down. o Allocate and free resources if interface is down before sending the config_led command. This is to make sure config_led command sending doesn't fail. o Clear QLCNIC_LED_ENABLE bit if beacon/ LED test fails to start.

2011-10-27stmmac: update normal descriptor structure (v2)Giuseppe CAVALLARO
This patch updates the normal descriptor structure to work fine on new GMAC Synopsys chips. Normal descriptors were designed on the old MAC10/100 databook 1.91 where some bits were reserved: for example the tx checksum insertion and rx checksum offload. The patch maintains the back-compatibility with old MAC devices (tested on STx7109 MAC10/100) and adds new fields that actually new GMAC devices can use. For example, STx7109 (MAC10/100) will pass from the platform tx_coe = 0, enh_desc = 0, has_gmac = 0. A platform like Loongson1B (GMAC) will pass: tx_coe = 1, enh_desc = 0, has_gmac = 1. Thanks to Kelvin, he enhanced the normal descriptors for GMAC (on MIPS Loongson1B platform).
