2009-09-08rt2x00: fix memory corruption in rf cache, add a sanity checkPavel Roskin
commit 6b26dead3ce97d016b57724b01974d5ca5c84bd5 upstream. Change rt2x00_rf_read() and rt2x00_rf_write() to subtract 1 from the rf register number. This is needed because the rf registers are enumerated starting with one. The size of the rf register cache is just enough to hold all registers, so writing to the highest register was corrupting memory. Add a check to make sure that the rf register number is valid.

2009-08-16ide: fix memory leak when flush command is issuedMaxime Bizon
commit bc146d23d1358af43f03793c3ad8c9f16bbcffcb upstream. I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory leak after writing lots of data, the kmalloc-96 slab cache keeps growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush is never kfreed. Commit a09485df9cda49fbde2766c86eb18a9cae585162 ("ide: move request type specific code from ide_end_drive_cmd() to callers (v3)") and f505d49ffd25ed062e76ffd17568d3937fcd338c ("ide: fix barriers support") cause this regression, cmd->rq must now be set for ide_complete_cmd to honor the IDE_TFLAG_DYN flag.

2009-08-16USB: devio: Properly do access_ok() checksMichael Buesch
commit 18753ebc8a98efe0e8ff6167afb31cef220c8e50 upstream. access_ok() checks must be done on every part of the userspace structure that is accessed. If access_ok() on one part of the struct succeeded, it does not imply it will succeed on other parts of the struct. (Does depend on the architecture implementation of access_ok()). This changes the __get_user() users to first check access_ok() on the data structure.

commit 346c17a6cf60375323adfaa4b8a9d841049f890e upstream. There are some broken devices that report multiple DMA xfer modes enabled at once (ATA spec doesn't allow it) but otherwise work fine with DMA so just delete ide_id_dma_bug(). [ As discovered by detective work by Frans and Bart, due to how handling of the ID block was handled before commit c419993 ("ide-iops: only clear DMA words on setting DMA mode") this check was always seeing zeros in the fields or other similar garbage. Therefore this check wasn't actually checking anything. Now that the tests actually check the real bits, all we see are devices that trigger the check yet work perfectly fine, therefore killing this useless check is the best thing to do. -DaveM ] Reported-by: Frans Pop <elendil@planet.nl> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S.

2009-08-16thinkpad-acpi: disable broken bay and dock subdriversHenrique de Moraes Holschuh
commit 550e7fd8afb7664ae7cedb398c407694e2bf7d3c upstream. Currently, the ThinkPad-ACPI bay and dock drivers are completely broken, and cause a NULL pointer derreference in kernel mode (and, therefore, an OOPS) when they try to issue events (i.e. on dock, undock, bay ejection, etc). OTOH, the standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27. In fact, it does a much better job of it than thinkpad-acpi ever did. It is just not worth the hassle to find a way to fix this crap without breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old, deprecated code that sees little testing or use. As a quick fix suitable for -stable backports, mark the thinkpad-acpi bay and dock subdrivers as BROKEN in Kconfig. The dead code will be removed by a later patch. This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

2009-08-16SCSI: libsas: reuse the original port when hotplugging phys in wide portsTom Peng
commit 5381837f125cc62ad703fbcdfcd7566fc81fd404 upstream. There's a hotplug problem in the way libsas allocates ports: it loops over the available ports first trying to add to an existing for a wide port and otherwise allocating the next free port. This scheme only works if the port array is packed from zero, which fails if a port gets hot unplugged and the array becomes sparse. In that case, a new port is formed even if there's a wide port it should be part of. Fix this by creating two loops over all the ports: the first to see if the phy should be part of a wide port and the second to form a new port in an empty port slot.

commit 7a777919bbeec3eac1d7904a728a60e9c2bb9c67 upstream. Requests to get max LUN, for certain USB storage devices, require a longer timeout before a correct reply is returned. This happens for a Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set to 0, thus losing functionality, because of the timeout occurring too quickly. Raising the timeout value fixes the issue and might help other devices to return a correct max LUN value as well.

2009-08-16E100: work around the driver using streaming DMA mapping for RX descriptors.Krzysztof Halasa
[ Upstream commit 303d67c288319768b19ed8dbed429fef7eb7c275 ] E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Unfortunately it fails to transfer skb->data ownership to the device after it reads the descriptor's status, breaking on non-coherent (e.g., ARM) platforms. This have to be converted to use coherent memory for the descriptors. Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2009-08-16be2net: Fix to avoid a crash seen on PPC with LRO and Jumbo frames.Ajit Khaparde
[ Upstream commit bd46cb6cf11867130a41ea9546dd65688b71f3c2 ] While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames. With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page. This patch is against the net-2.6 tree. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-08-16iwlwifi: only show active power level via sysfsReinette Chatre
commit 872ed1902f511a8947021c562f5728a5bf0640b5 upstream. This changes the power_level file to adhere to the "one value per file" sysfs rule. The user will know which power level was requested as it will be the number just written to this file. It is thus not necessary to create a new sysfs file for this value. In addition it fixes a problem where powertop's parsing expects this value to be the first value in this file without any descriptions.

commit fe2c4d018fc6127610fef677e020b3bb41cfaaaf upstream. ata_eh_reset() was missing error return handling after follow-up SRST allowing EH to continue the normal probing path after reset failure. This was discovered while testing new WD 2TB drives which take longer than 10 secs to spin up and cause the first follow-up SRST to time out.

2009-07-30Input: wistron_btns - recognize Maxdata Pro 7000 notebooksGiuseppe Mazzotta
commit e705cee427e319665969ef7ac664f3612dec8899 upstream. This patch adds DMI information to automatically load the correct layout for the Maxdata Pro 7000X/DX notebook models. Such notebooks are clones of Fujitsu Amilo V2000, the hook for the v2000 is being used and I have tested that perfectly works. The immediate result of integrating this patch is that the five special buttons will work on these specific notebook models and that the RF killswitch will not be activated after suspend. This patch definitively obsoletes the fsam7400 module which I was still needing to enable wifi and to fix the RF killswitch suspend problem; in the current 2.6.30 kernel it is necessary to load the wistron_btns module with options 'force=1 keymap=1557/MS2141', which was not anyway a complete workaround.

commit 69885683d22d8c05910fd808c01fdce1322739b4 upstream. The recent commit 7513c2a761d69d2a93f17146b3563527d3618ba0 (dm raid1: add is_remote_recovering hook for clusters) changed do_writes() to update the ms->writes list but forgot to wake up kmirrord to process it. The rule is that when anything is being added on ms->reads, ms->writes or ms->failures and the list was empty before we must call wakeup_mirrord (for immediate processing) or delayed_wake (for delayed processing). Otherwise the bios could sit on the list indefinitely.

2009-07-30block: fix sg SG_DXFER_TO_FROM_DEV regressionFUJITA Tomonori
commit ecb554a846f8e9d2a58f6d6c118168a63ac065aa upstream. I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use the block layer mapping API (2.6.28). Douglas Gilbert explained SG_DXFER_TO_FROM_DEV: http://www.spinics.net/lists/linux-scsi/msg37135.html = The semantics of SG_DXFER_TO_FROM_DEV were: - copy user space buffer to kernel (LLD) buffer - do SCSI command which is assumed to be of the DATA_IN (data from device) variety. This would overwrite some or all of the kernel buffer - copy kernel (LLD) buffer back to the user space. The idea was to detect short reads by filling the original user space buffer with some marker bytes ("0xec" it would seem in this report). The "resid" value is a better way of detecting short reads but that was only added this century and requires co-operation from the LLD. = This patch changes the block layer mapping API to support this semantics. This simply adds another field to struct rq_map_data and enables __bio_copy_iov() to copy data from user space even with READ requests. It's better to add the flags field and kills null_mapped and the new from_user fields in struct rq_map_data but that approach makes it difficult to send this patch to stable trees because st and osst drivers use struct rq_map_data (they were converted to use the block layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer mapping API. zhou sf reported this regiression and tested this patch: http://www.spinics.net/lists/linux-scsi/msg37128.html http://www.spinics.net/lists/linux-scsi/msg37168.html Reported-by: zhou sf <sxzzsf@gmail.com> Tested-by: zhou sf <sxzzsf@gmail.com> Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-07-30vc: create vcs(a) devices for consolesKay Sievers
commit c46a7aec556ffdbdb7357db0b05904b176cb3375 upstream. The buffer for the consoles are unconditionally allocated at con_init() time, which miss the creation of the vcs(a) devices.
