| | | | | | | | | | http://bugzilla.kernel.org/show_bug.cgi?id=13312 at76_dwork_hw_scan holds a mutex while calling ieee80211_scan_completed, which then calls at76_config which needs the same mutex.

* iwlwifi: do not cancel delayed work inside spin_lock_irqsaveReinette Chatre2009-05-203-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling cancel_delayed_work() from inside spin_lock_irqsave, introduces a potential deadlock. As explained by Johannes Berg <johannes@sipsolutions.net> A - lock T - timer phase CPU 1 CPU 2 --------------------------------------------- some place that calls cancel_timer_sync() (which is the | code) lock-irq(A) | "lock-irq"(T) | "unlock"(T) | wait(T) unlock(A) timer softirq "lock"(T) run(T) "unlock"(T) irq handler lock(A) unlock(A) Now all that again, interleaved, leading to deadlock: lock-irq(A) "lock"(T) run(T) IRQ during or maybe before run(T) --> lock(A) "lock-irq"(T) wait(T) We fix this by moving the call to cancel_delayed_work() into workqueue. There are cases where the work may not actually be queued or running at the time we are trying to cancel it, but cancel_delayed_work() is able to deal with this. Also cleanup iwl_set_mode related to this call. This function (iwl_set_mode) is only called when bringing interface up and there will thus not be any scanning done. No need to try to cancel scanning.

* ath5k: fix exp off-by-one when computing OFDM delta slopeForrest Zhang2009-05-201-3/+3
| | | | | | | | | | | | | | | Commit e8f055f0c3b ("ath5k: Update reset code") subtly changed the code that computes floating point values for the PHY3_TIMING register such that the exponent is off by a decimal point, which can cause problems with OFDM channel operation. get_bitmask_order() actually returns the highest bit set plus one, whereas the previous code wanted the highest bit set. Instead, use ilog2 which is what this code is really calculating. Also check coef_scaled to handle the (invalid) case where we need log2(0).

| * ath5k: update channel in sw state after stopping RX and TXBob Copeland2009-05-111-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a non-theoretical race condition when transmitting and receiving frames during a scan. If the channel or operating band changes while processing status descriptors in the tasklets, ath5k will incorrectly use the new channel and band when reporting the rates, even if the frame was actually sent on a previous channel.

| * iwlwifi: update key flags at time key is setReinette Chatre2009-05-041-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to be symmetrical in what is done when key is set and cleared. This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info(). Fix this by setting flags in iwl_set_tkip_dynamic_key_info(). Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging TX issues it is helpful to know the seq nr of the frame being transmitted. The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at.

| | | | | | | | | | | | | | | | | | | | | | After suspend & resume the rt2x00 devices won't wakeup anymore due to a broken register information setup. The most important problem is the release of the EEPROM buffer which is completely cleared and never read again after the suspend.

The problem is that if ieee80211_register_hw fails, we call rt2x00lib_remove_hw twice: * first inside rt2x00lib_probe_hw upon failure of ieee80211_register_hw * error status is returned to rt2x00lib_probe_dev, which then sees it and calls in this case rt2x00lib_remove_dev that will again run rt2x00lib_remove_hw Prevent this avoiding calling rt2x00lib_remove_hw inside rt2x00lib_probe_hw Problem was detected with CONFIG_DEBUG_PAGEALLOC=y, CONFIG_SLUB_DEBUG=y, CONFIG_SLUB_DEBUG_ON=y, that dumps this with no firmware available: rt61pci 0000:00:07.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 wmaster0 (rt61pci): not using net_device_ops yet phy0: Selected rate control algorithm 'pid' phy0: Failed to initialize wep: -2 phy0 -> rt2x00lib_probe_dev: Error - Failed to initialize hw. ============================================================================= BUG kmalloc-128: Object already free ----------------------------------------------------------------------------- INFO: Allocated in rt61pci_probe_hw+0x3e5/0x6e0 [rt61pci] age=340 cpu=0 pid=21 INFO: Freed in rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] age=0 cpu=0 pid=21 INFO: Slab 0xc13ac3e0 objects=23 used=10 fp=0xdd59f6e0 flags=0x400000c3 INFO: Object 0xdd59f6e0 @offset=1760 fp=0xdd59f790 Bytes b4 0xdd59f6d0: 15 00 00 00 b2 8a fb ff 5a 5a 5a 5a 5a 5a 5a 5a ....².ûÿZZZZZZZZ Object 0xdd59f6e0: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f6f0: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f700: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f710: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f720: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f730: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f740: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f750: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b a5 kkkkkkkkkkkkkkk¥ Redzone 0xdd59f760: bb bb bb bb »»»» Padding 0xdd59f788: 5a 5a 5a 5a 5a 5a 5a 5a ZZZZZZZZ Pid: 21, comm: stage1 Not tainted 2.6.29.1-desktop-1.1mnb #1 Call Trace: [<c01abbb3>] print_trailer+0xd3/0x120 [<c01abd37>] object_err+0x37/0x50 [<c01acf57>] __slab_free+0xe7/0x2f0 [<c01ad1de>] kfree+0x7e/0xd0 [<e0e4a239>] ? rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4a239>] ? rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4a239>] rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4acc7>] rt2x00lib_remove_dev+0x37/0x50 [rt2x00lib] [<e0e4b087>] rt2x00lib_probe_dev+0x1a7/0x3b0 [rt2x00lib] [<e0eb288f>] rt2x00pci_probe+0xdf/0x1ee [rt2x00pci] [<c026b9ee>] local_pci_probe+0xe/0x10 [<c026c750>] pci_device_probe+0x60/0x80 [<c02d5c2a>] driver_probe_device+0x9a/0x2e0 [<c02d5ef9>] __driver_attach+0x89/0x90 [<c02d541b>] bus_for_each_dev+0x4b/0x70 [<c026c690>] ? pci_device_remove+0x0/0x40 [<c02d59d9>] driver_attach+0x19/0x20 [<c02d5e70>] ? __driver_attach+0x0/0x90 [<c02d4cef>] bus_add_driver+0x1cf/0x2a0 [<c026c690>] ? pci_device_remove+0x0/0x40 [<c02d60c9>] driver_register+0x69/0x140 [<c026c9b0>] __pci_register_driver+0x40/0x80 [<e0ecc000>] ? rt61pci_init+0x0/0x19 [rt61pci] [<e0ecc017>] rt61pci_init+0x17/0x19 [rt61pci] [<c0101116>] do_one_initcall+0x26/0x1c0 [<c01ab90c>] ? slab_pad_check+0x3c/0x120 [<c01ab90c>] ? slab_pad_check+0x3c/0x120 [<c01ac8da>] ? check_object+0xda/0x210 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01ad09e>] ? __slab_free+0x22e/0x2f0 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01687ec>] ? stop_machine_destroy+0x3c/0x40 [<c015e515>] ? load_module+0xa5/0x1c50 [<e0ec5000>] ? rt61pci_eepromregister_read+0x0/0x40 [rt61pci] [<e0eb2000>] ? rt2x00pci_write_tx_data+0x0/0x90 [rt2x00pci] [<c03ac2fb>] ? mutex_lock+0xb/0x20 [<c03ac2fb>] ? mutex_lock+0xb/0x20 [<c017ad16>] ? tracepoint_update_probe_range+0x76/0xa0 [<c017ad6f>] ? tracepoint_module_notify+0x2f/0x40 [<c03b02ed>] ? notifier_call_chain+0x2d/0x70 [<c014f0ed>] ? __blocking_notifier_call_chain+0x4d/0x60 [<c014f11a>] ? blocking_notifier_call_chain+0x1a/0x20 [<c0160156>] sys_init_module+0x96/0x1d0 [<c019dad6>] ? sys_munmap+0x46/0x60 [<c0105546>] syscall_call+0x7/0xb FIX kmalloc-128: Object at 0xdd59f6e0 not freed rt61pci 0000:00:07.0: PCI INT A disabled rt61pci: probe of 0000:00:07.0 failed with error -2 Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
