2010-06-07asix: check packet size against mtu+ETH_HLEN instead of ETH_FRAME_LENJussi Kivilinna
Driver checks received packet is too large in asix_rx_fixup() and fails if it is. Problem is that MTU might be set larger than 1500 and asix fails to work correctly with VLAN tagged packets. The check should be 'dev->net->mtu + ETH_HLEN' instead. Tested with AX88772. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-06-06r8169: fix random mdio_write failuresTimo Teräs
Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856ff (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state.

2010-06-05iwlwifi: move sysfs_create_group to post request firmwareEmmanuel Grumbach
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>

Commit 56d1de0a21db28e41741cfa0a66e18bc8d920554, "ath5k: clean up filter flags setting" introduced a regression in monitor mode such that the promisc filter flag would get lost.

2010-06-02korina: fix deadlock on RX FIFO overrunPhil Sutter
By calling korina_restart(), the IRQ handler tries to disable the interrupt it's currently serving. This leads to a deadlock since disable_irq() waits for any running IRQ handlers to finish before returning. This patch addresses the issue by turning korina_restart() into a workqueue task, which is then scheduled when needed. Reproducing the deadlock is easily done using e.g. GNU netcat to send large amounts of UDP data to the host running this driver. Note that the same problem (and fix) applies to TX FIFO underruns, but apparently these are less easy to trigger. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: David S.

This causes free_netdev() to hang during rmmod. We fix this by calling netif_napi_del() during ->close(). Also, bnx2_init_napi() must not be in the __devinit section since it is called by ->open().

Grant patches added an of mach table to struct device_driver. However, while he changed the macio device code to use that, he left the match table pointer in struct macio_driver and didn't update drivers to use the "new" one, thus breaking the probing. This completes the change by moving all drivers to setup the "new" one, removing all traces of the old one, and while at it (since it changes the exact same locations), I also remove two other duplicates from struct driver which are the name and owner fields.

2010-05-29fs_enet: Adjust BDs after tx errorMark Ware
This patch fixes an occasional transmit lockup in the mac-fcc which occurs after a tx error. The test scenario had the local port set to autoneg and the other end fixed at 100FD, resulting in a large number of late collisions. According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after a tx error occurs, TBPTR may sometimes point beyond BDs still marked as ready. This patch walks back through the BDs and points TBPTR to the earliest one marked as ready. Tested on a custom board with a MPC8280.

2010-05-28ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is usedVasanthakumar Thiagarajan
This bug was introduced by the following commit Author: Vasanthakumar Thiagarajan <vasanth@atheros.com> Date: Thu Apr 15 17:38:46 2010 -0400 ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(), this may result in a rate scaling with wrong feedback (number of unacked frames in this case). It is the last one in the chain of buffers for an aggregate frame that should be checked. Also it misses the initialization of this field in the buffer, this may lead to a situation where we stop the sw retransmission of failed subframes associated to this buffer.

ath_print in xmit.c should say "Reseting hardware" instead of Resetting HAL!(since HAL is being fazed out). dmesg shows: [ 8660.899624] ath: Failed to stop TX DMA in 100 msec after killing last frame [ 8660.899676] ath: Unable to stop TxDMA.

2010-05-28netdev/fec: fix ifconfig eth0 down hang issueBryan Wu
BugLink: http://bugs.launchpad.net/bugs/559065 In fec open/close function, we need to use phy_connect and phy_disconnect operation before we start/stop phy. Otherwise it will cause system hang. Only call fec_enet_mii_probe() in open function, because the first open action will cause NULL pointer error. Signed-off-by: Bryan Wu <bryan.wu@canonical.com> Signed-off-by: David S.

2010-05-28cnic: Fix context memory init. on 5709.Michael Chan
We need to zero context memory on 5709 in the function cnic_init_context(). Without this, iscsid restart on 5709 will not work because of stale data. TX context blocks should not be initialized by cnic_init_context() because of the special remapping on 5709. Update version to 2.1.2.
