2013-02-25usbnet: smsc95xx: fix broken runtime suspendMing Lei
Commit b2d4b150(smsc95xx: enable dynamic autosuspend) implements autosuspend, but breaks current runtime suspend, such as: when the interface becomes down, the usb device can't be put into runtime suspend any more. This patch fixes the broken runtime suspend. Cc: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: Ming Lei <ming.lei@canonical.com> Signed-off-by: David S.

2013-02-25usbnet: smsc95xx: fix suspend failureMing Lei
The three below functions: smsc95xx_enter_suspend0() smsc95xx_enter_suspend1() smsc95xx_enter_suspend2() return > 0 in case of success, so they will cause smsc95xx_suspend() to return > 0 and cause suspend failure. The bug is introduced in commit 3b9f7d(smsc95xx: fix error handling in suspend failure case).

2013-02-25b43: Fix lockdep splat on module unloadLarry Finger
On unload, b43 produces a lockdep warning that can be summarized in the following way: ====================================================== [ INFO: possible circular locking dependency detected ] 3.8.0-wl+ #117 Not tainted ------------------------------------------------------- modprobe/5557 is trying to acquire lock: ((&wl->firmware_load)){+.+.+.}, at: [<ffffffff81062160>] flush_work+0x0/0x2a0 but task is already holding lock: (rtnl_mutex){+.+.+.}, at: [<ffffffff813bd7d2>] rtnl_lock+0x12/0x20 which lock already depends on the new lock. [ INFO: possible circular locking dependency detected ] ====================================================== The full output is available at http://lkml.indiana.edu/hypermail/linux/kernel/1302.3/00060.html. To summarize, commit 6b6fa58 added a 'cancel_work_sync(&wl->firmware_load)' call in the wrong place. The fix is to move the cancel_work_sync() call to b43_bcma_remove() and b43_ssb_remove().

commit "ip_gre: allow CSUM capable devices to handle packets" aa0e51cdda005cd37e2, broke GRE_CSUM case. GRE_CSUM needs checksum computed for inner packet. Therefore csum-calculation can not be offloaded if tunnel device requires GRE_CSUM.

2013-02-25ACPI: Overriding ACPI tables via initrd only works with an initrd and on X86Thomas Renninger
Reflect this dependency in Kconfig, to prevent build failures. Shorten the config description as suggested by Borislav Petkov. Finding a suitable memory area to store the modified table(s) has been taken over from arch/x86/kernel/setup.c and makes use of max_low_pfn_mapped: memblock_find_in_range(0, max_low_pfn_mapped,...) This one is X86 specific. It may not be hard to extend this functionality for other ACPI aware architectures if there is need for. For now make this feature only available for X86 to avoid build failures on IA64, compare with: https://bugzilla.kernel.org/show_bug.cgi?id=54091 Signed-off-by: Thomas Renninger <trenn@suse.de> Link: http://lkml.kernel.org/r/1361538742-67599-3-git-send-email-trenn@suse.de Signed-off-by: H.

2013-02-25IPoIB: Free ipoib neigh on path record failure so path rec queries are retriedRoland Dreier
If IPoIB fails to look up a path record (eg if it tries during an SM failover when one SM is dead but the new one hasn't taken over yet), the driver ends up with a neighbour structure but no address handle (AH). There's no mechanism to recover from this: any further packets sent to this destination will be silently dumped in ipoib_start_xmit(). Fix this by freeing the neighbour structures when a path rec query fails, so that the next packet queued to be sent will trigger a new path record query.

2013-02-25IB/srp: Fail I/O requests if the transport is offlineBart Van Assche
If an SRP target is no longer reachable and srp_reset_host() fails to reconnect then ib_srp will invoke scsi_remove_host(). That function will invoke __scsi_remove_device() for each LUN. And that last function will change the device state from SDEV_TRANSPORT_OFFLINE into SDEV_CANCEL. Certain user space software, e.g. older versions of multipathd, continue queueing I/O to SCSI devices that are in the SDEV_CANCEL state. If these I/O requests are submitted as SG_IO that means that the REQ_PREEMPT flag will be set and hence that these requests will be passed to srp_queuecommand(). These requests will time out. If new requests are queued fast enough from user space these active requests will prevent __scsi_remove_device() to finish. Avoid this by failing I/O requests in the SDEV_CANCEL state if the transport is offline. Introduce a new variable to keep track of the transport state instead of failing requests if (!target->connected || target->qp_in_error), so that the SCSI error handler has a chance to retry commands after a transport layer failure occurred.

2013-02-25IB/srp: Avoid endless SCSI error handling loopBart Van Assche
If a SCSI command times out it is passed to the SCSI error handler. The SCSI error handler will try to abort the commands that timed out. If aborting fails, a device reset will be attempted. If the device reset also fails a host reset will be attempted. If the host reset also fails the whole procedure will be repeated. srp_abort() and srp_reset_device() fail for a QP in the error state. srp_reset_host() fails after host removal has started. Hence if the SCSI error handler gets invoked after host removal has started and with the QP in the error state an endless loop will be triggered. Modify the SCSI error handling functions in ib_srp as follows: - Abort SCSI commands properly even if the QP is in the error state. - Make srp_reset_host() reset SCSI requests even after host removal has already started or if reconnecting fails.

Discussion was continuing after patch application, trying to figure out how to best mesh exported data with the installers, boot-time agents and other parties that want this info. 2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing the wonderfulness of sane power management to your CD/DVD device. Includes one SCSI-subsystem patch (with appropriate ACKs), adding runtime PM support to 'sr' driver. That is the ZPODD interaction bits. Patchset went through some 13 revisions before it got here; kudos to Intel for persistence. 3) pata_samsung_cf: use devm_clk_get() 4) more ata_piix, ahci PCI IDs 5) Add SATA driver for R-Car SoC 6) Convert libata to use devm_ioremap_resource (Note: I think Greg sent this to you, also) 7) Set proper Sense Key (SK) in the SCSI simulator when ATA passthrough indicates check condition.

2013-02-24tty vt: fix character insertion overflowNicolas Pitre
Commit 81732c3b2fed ("tty vt: Fix line garbage in virtual console on command line edition") broke insert_char() in multiple ways. Then commit b1a925f44a3a ("tty vt: Fix a regression in command line edition") partially fixed it. However, the buffer being moved is still too large and overflowing beyond the end of the current line, corrupting existing characters on the next line. Example test case: echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B" Expected result: ab c de Current result: ab c e Needless to say that this is very annoying when inserting words in the middle of paragraphs with certain text editors.

2013-02-24vmxnet3: fix ethtool ring buffer size settingNeil Horman
Noticed that vmxnet3's get_ringparam function was returning the summation of all ring buffers on a NIC, rather than just the size of any one ring. This causes problems when a vmxnet3 instance has multiple queues, as ethtool, when setting ring parameters, first gets the current ring parameters to set the existing values in the set_ringparm commannd. The result is, that unless both rx and tx ring sizes are set in a single operation, which ever ring is not set will silently have its ring count multiplied by the number of queues on the NIC until it reaches a driver defined maxiumum value. Fix it by not multiplying the rx and tx ring sizes by the number of queues in the system, like every other driver. Tested by myself successfully.
