commit 2f5899a39dcffb404c9a3d06ad438aff3e03bf04 upstream. I am not sure what happened. It looks like we have always leaked the q->queue that is allocated from the kfifo_init call. nab finally noticed that we were leaking and this patch fixes it by adding a kfree call to iscsi_pool_free. kfifo_free is not used per kfifo_init's instructions to use kfree.

2009-02-20Fix Intel IOMMU write-buffer flushingDavid Woodhouse
commit ca77fde8e62cecb2c0769052228d15b901367af8 upstream. This is the cause of the DMA faults and disk corruption that people have been seeing. Some chipsets neglect to report the RWBF "capability" -- the flag which says that we need to flush the chipset write-buffer when changing the DMA page tables, to ensure that the change is visible to the IOMMU. Override that bit on the affected chipsets, and everything is happy again. Thanks to Chris and Bhavesh and others for helping to debug.

commit d89293abd95bfd7dd9229087d6c30c1464c5ac83 upstream. The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary speed down warning messages but it accidentally disabled SATA link spd down during configuration phase after reset where PIO mode is always zero.

[ Upstream commit e918085aaff34086e265f825dd469926b1aec4a4 ] 802.1Q expanded the maximum ethernet frame size by 4 bytes for the VLAN tag. We're not taking this into account in virtio_net, which means the buffers we provide to the backend in the virtqueue RX ring aren't big enough to hold a full MTU VLAN packet. For QEMU/KVM, this results in the backend exiting with a packet truncation error.

2009-02-17tun: Fix unicast filter overflowAlex Williamson
[ Upstream commit cfbf84fcbcda98bb91ada683a8dc8e6901a83ebd ] Tap devices can make use of a small MAC filter set via the TUNSETTXFILTER ioctl. The filter has a set of exact matches plus a hash for imperfect filtering of additional multicast addresses. The current code is unbalanced, adding unicast addresses to the multicast hash, but only checking the hash against multicast addresses. This results in the filter dropping unicast addresses that overflow the exact filter. The fix is simply to disable the filter by leaving count set to zero if we find non-multicast addresses after the exact match table is filled.

[ Upstream commit 71822faa3bc0af5dbf5e333a2d085f1ed7cd809f ] From: Ilkka Virta <itvirta@iki.fi> In the lockup situation the driver seems to go off in an eternal storm of interrupts right after calling request_irq(). It doesn't actually do anything interesting in the interrupt handler. Since connecting the link afterwards works, something later in initialization must fix this. Looking at gem_do_start() and gem_open(), it seems that the only thing done while opening the device after the request_irq(), is a call to napi_enable(). I don't know what the ordering requirements are for the initialization, but I boldly tried to move the napi_enable() call inside gem_do_start() before the link state is checked and interrupts subsequently enabled, and it seems to work for me. Doesn't even break anything too obvious... Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-02-17nbd: fix I/O hang on disconnected nbdsPaul Clements
commit 4d48a542b42747c36a5937447d9c3de7c897ea50 upstream. Fix a problem that causes I/O to a disconnected (or partially initialized) nbd device to hang indefinitely. To reproduce: # ioctl NBD_SET_SIZE_BLOCKS /dev/nbd23 514048 # dd if=/dev/nbd23 of=/dev/null bs=4096 count=1 ...hangs... This can also occur when an nbd device loses its nbd-client/server connection. Although we clear the queue of any outstanding I/Os after the client/server connection fails, any additional I/Os that get queued later will hang. This bug may also be the problem reported in this bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12277 Testing would need to be performed to determine if the two issues are the same. This problem was introduced by the new request handling thread code ("NBD: allow nbd to be used locally", 3/2008), which entered into mainline around 2.6.25. The fix, which is fairly simple, is to restore the check for lo->sock being NULL in do_nbd_request. This causes I/O to an uninitialized nbd to immediately fail with an I/O error, as it did prior to the introduction of this bug.

2009-02-12ipw2200: fix scanning while associatedHelmut Schaa
commit 14a4dfe2ff8c353f59ae8324059ded1cfe22c7d9 upstream. This patch fixes sporadic firmware restarts when scanning while associated. The firmware will quietly cancel a scan (while associated) if the dwell time for a channel to be scanned is larger than the time it may stay away from the operating channel (because of DTIM catching). Unfortunately the driver is not notified about the canceled scan and therefore the scan watchdog timeout will be hit and the driver causes a firmware restart which results in disassociation. This mainly happens on passive channels which use a dwell time of 120 whereas a typical beacon interval is around 100. The patch changes the dwell time for passive channels to be slightly smaller than the actual beacon interval to work around the firmware issue. Furthermore the number of allowed beacon misses is increased from one to three as otherwise most scans (while associated) won't complete successfully. However scanning while associated will still fail in corner cases such as a beacon intervals below 30. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

commit 3419c75e15f82c3ab09bd944fddbde72c9e4b3ea upstream. We only want to disable ASPM when the last function is removed from the parent's device list. We determine this by checking to see if the parent's device list is completely empty. Unfortunately, we never hit that code because the parent is considered an upstream port, and never had an ASPM link_state associated with it. The early check for !link_state causes us to return early, we never discover that our device list is empty, and thus we never remove the downstream ports' link_state nodes. Instead of checking to see if the parent's device list is empty, we can check to see if we are the last device on the list, and if so, then we know that we can clean up properly.

commit 0a3db1cec5d476804185114ff5d1845aed3936b3 upstream. According to the Spec the first two elements in the _BCL package won't be regarded as the available brightness level. The first is the brightness when full power is connected to the box(It means that the AC adapter is plugged). The second is the brightness level when the box is on battery. If the first two elements are still used while finding the next brightness level, it will fall back to the lowest level when keeping on pressing hotkey. (On some boxes the brightness will be changed twice when hotkey is pressed once. One is in the ACPI video driver. The other is changed by sys I/F. In the ACPI video driver the first two elements will be used while changing the brightness. But the first two elements is skipped while using sys I/F. In such case there exists the inconsistency). So he first two elements had better be skipped while showing the available brightness or finding the next brightness level. http://bugzilla.kernel.org/show_bug.cgi?id=12450 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 15b2bee22a0390d951301b53e83df88d0350c499 upstream. A nasty bug was found where an MTU change (or anything else that caused a reset) could race with the interrupt code. The interrupt code was entered by a shared interrupt during the MTU change. This change prevents the interrupt code from running while the driver is in the middle of its reset path.

eeepc-laptop init commit 7695fb04aca62e2d8a7ca6ede50f6211e1d71e53 upstream. I got the following oops while changing the backlight brightness during startup. When it happens, it prevents use of the hotkeys, Fn-Fx, and the lid button. It's a clear use-before-init, as I verified by testing with an appropriately-placed "else printk".

Commit c8c4707cf7ca8ff7dcc1653447e48cb3de0bf114 upstream. According to https://bugs.launchpad.net/bugs/294391 - 3rd generation iPods need the "fix capacity" workaround after all (apparently they crash after the last sector was accessed), - 2nd generation iPods need the "128 kB maximum request size" workaround. Alas both iPod generations feature the same model ID in the config ROM, hence we can only define a shared quirks list entry for them. Luckily the fix capacity workaround did not show a negative effect in Jarod's tests with 2nd gen. iPod. A side note: Apple computers in target mode (or at least an x86 Mac mini) don't have firmware_version and model_id, hence none of the iPod quirks list entries is active for them.

2009-02-12firewire: ohci: increase AT req. retries, fix ack_busy_X from Panasonic ↵Stefan Richter
camcorders and others Commit 8b7b6afaa84708d08139daa08538ca3e56c351f1 upstream. Camcorders have a tendency to fail read requests to their config ROM and write request to their FCP command register with ack_busy_X. This has become a problem with newer kernels and especially Panasonic camcorders, causing AV/C in dvgrab and kino to fail. Dvgrab for example frequently logs "send oops"; kino reports loss of AV/C control. I suspect that lower CPU scheduling latencies in newer kernels made this issue more prominent now. According to https://sourceforge.net/tracker/?func=detail&atid=114103&aid=2492640&group_id=14103 this can be fixed by configuring the FireWire controller for more hardware retries for request transmission; these retries are evidently more successful than libavc1394's own retry loop (typically 3 tries on top of hardware retries). Presumably the same issue has been reported at https://bugzilla.redhat.com/show_bug.cgi?id=449252 and https://bugzilla.redhat.com/show_bug.cgi?id=477279 . In a quick test with a JVC camcorder (which didn't malfunction like the reported camcorders), this change decreased the number of ack_busy_X from 16 in three runs of dvgrab to 4 in three runs of the same capture duration.
