2010-06-06iwlwifi: move sysfs_create_group to post request firmwareEmmanuel Grumbach1-159/+159
Move the sysfs_create_group to iwl_ucode_callback after we have safely got the firmware. The motivation to do this comes from a warning from lockdep which detected that we request priv->mutex while holding s_active during a sysfs request (show_statistics in the example copy pasted). The reverse order exists upon request_firmware: request_firmware which is a sysfs operation that requires s_active is run under priv->mutex. This ensures that we don't get sysfs request before we finish to request the firmware, avoiding this deadlock. ======================================================= [ INFO: possible circular locking dependency detected ] ------------------------------------------------------- cat/2595 is trying to acquire lock: (&priv->mutex){+.+.+.}, at: [<facfa598>] show_statistics+0x48/0x100 [iwlagn] but task is already holding lock: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (s_active){++++.+}: [<c0489b74>] __lock_acquire+0xc44/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c0581499>] sysfs_addrm_finish+0xe9/0x180 [<c057f64a>] sysfs_hash_and_remove+0x4a/0x80 [<c05829d4>] sysfs_remove_group+0x44/0xd0 [<c0714b75>] dpm_sysfs_remove+0x15/0x20 [<c070dac8>] device_del+0x38/0x170 [<c070dc1e>] device_unregister+0x1e/0x60 [<c071838d>] _request_firmware+0x29d/0x550 [<c07186c7>] request_firmware+0x17/0x20 [<fad01bf1>] iwl_mac_start+0xb1/0x1230 [iwlagn] [<fa46ba06>] ieee80211_open+0x436/0x6f0 [mac80211] [<c0808cd2>] dev_open+0x92/0xf0 [<c0808b2b>] dev_change_flags+0x7b/0x190 [<c08148e8>] do_setlink+0x178/0x3b0 [<c0815169>] rtnl_setlink+0xf9/0x130 [<c081453b>] rtnetlink_rcv_msg+0x1bb/0x1f0 [<c0827ce6>] netlink_rcv_skb+0x86/0xa0 [<c081436c>] rtnetlink_rcv+0x1c/0x30 [<c08279c3>] netlink_unicast+0x263/0x290 [<c0828768>] netlink_sendmsg+0x1c8/0x2a0 [<c07f85fd>] sock_sendmsg+0xcd/0x100 [<c07f964d>] sys_sendmsg+0x15d/0x290 [<c07f9e6b>] sys_socketcall+0xeb/0x2a0 [<c040ad9f>] sysenter_do_call+0x12/0x38 -> #0 (&priv->mutex){+.+.+.}: [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c08bb358>] __mutex_lock_common+0x58/0x470 [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c052880f>] vfs_read+0x9f/0x190 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 other info that might help us debug this: 3 locks held by cat/2595: #0: (&buffer->mutex){+.+.+.}, at: [<c057fe25>] sysfs_read_file+0x35/0x190 #1: (s_active){++++.+}, at: [<c0580ecd>] sysfs_get_active_two+0x2d/0x50 #2: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 stack backtrace: Pid: 2595, comm: cat Not tainted 2.6.33-tp-rc4 #2 Call Trace: [<c08b99ab>] ? printk+0x1d/0x22 [<c0487752>] print_circular_bug+0xc2/0xd0 [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c0478d81>] ? sched_clock_cpu+0x121/0x180 [<c048a1ed>] lock_acquire+0x8d/0x110 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb358>] __mutex_lock_common+0x58/0x470 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c0580cf9>] ? sysfs_get_active+0x69/0xb0 [<facfa550>] ? show_statistics+0x0/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c05ff314>] ? security_file_permission+0x14/0x20 [<c0528242>] ? rw_verify_area+0x62/0xd0 [<c052880f>] vfs_read+0x9f/0x190 [<c047745b>] ? up_read+0x1b/0x30 [<c057fdf0>] ? sysfs_read_file+0x0/0x190 [<c04af3b4>] ? audit_syscall_entry+0x1f4/0x220 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-06-01ath5k: wake queues on resetBruno Randolf1-14/+3
We can wake all queues after a chip reset since everything should be set up and we are ready to transmit. If we don't do that we might end up starting up with stopped queues, not beeing able to transmit. (This started to happen after "ath5k: clean up queue manipulation" but since periodic calibration also stopped and started the queues this effect was hidden most of the time). This way we can also get rid of the superfluous ath5k_reset_wake() function. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2010-05-24ath5k: consistently use rx_bufsize for RX DMABruno Randolf1-3/+4
We should use the same buffer size we set up for DMA also in the hardware descriptor. Previously we used common->rx_bufsize for setting up the DMA mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the descriptor itself. The problem is that skb_tailroom(skb) can give us a larger value than the size we set up for DMA before. This allows the hardware to write into memory locations not set up for DMA. In practice this should rarely happen because all packets should be smaller than the maximum 802.11 packet size. On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559 bytes length (including padding for cache alignment) but sbk_tailroom() was 2592. Just consistently use rx_bufsize for all RX DMA memory sizes. Also use the return value of the descriptor setup function.

2010-05-21iwlwifi: fix internal scan raceReinette Chatre1-3/+18
It is possible for internal scan to race against itself if the device is not returning the scan results from first requests. What happens in this case is the cleanup done during the abort of the first internal scan also cleans up part of the new scan, causing it to access memory it shouldn't. Here are details: * First internal scan is triggered and scan command sent to device. * After seven seconds there is no scan results so the watchdog timer triggers a scan abort. * The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for failed scan. * During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING and queue the "scan_completed" work. ** At this time, since the problem that caused the internal scan in first place is still present, a new internal scan is triggered. The behavior at this point is a bit different between 2.6.34 and 2.6.35 since 2.6.35 has a lot of this synchronized. The rest of the race description will thus be generalized. ** As part of preparing for the scan "is_internal_short_scan" is set to true. * At this point the completion work for fist scan is run. As part of this there is some locking missing around the "is_internal_short_scan" variable and it is set to "false". ** Now the second scan runs and it considers itself a real (not internal0 scan and thus causes problems with wrong memory being accessed. The fix is twofold. * Since "is_internal_short_scan" should be protected by mutex, fix this in scan completion work so that changes to it can be serialized. * Do not queue a new internal scan if one is in progress.

This adds support for a new copper device for 82599, device id 0x151c. This 82599 10GBase-T device uses the PHY's internal temperature sensor to guard against over-temp conditions. In this scenario the PHY will be put in a low power mode and link will no longer be able to transmit or receive any data. When this occurs, the over-temp interrupt is latched and driver logs this error message. A HW reset or power cycle is required to clear this status.

For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency.

2010-05-19ixgbe: fix header len when unsplit packet overflows to data bufferShannon Nelson1-2/+3
When in packet split mode, packet type is not recognized, and the packet is larger than the header size, the 82599 overflows the packet into the data area, but doesn't set the HDR_LEN field. We can safely assume the length is the current header size. This fixes an obscure corner case that can be triggered by non-ip packet headers or (more likely) by disabling the L2 packet recognition.
