2011-05-06cciss: do a better job of detecting controller reset failureStephen M. Cameron
Detect failure of controller reset by noticing if the 32 bytes of "driver version" we store on the hardware in the config table fail to get zeroed out. Previously we noticed if the controller did not transition to "simple mode", but this did not detect reset failure if the controller was already in simple mode prior to the reset attempt (e.g. due to module parameter hpsa_simple_mode=1).

2011-04-21block: don't block events on excl write for non-optical devicesTejun Heo
Disk event code automatically blocks events on excl write. This is primarily to avoid issuing polling commands while burning is in progress. This behavior doesn't fit other types of devices with removeable media where polling commands don't have adverse side effects and door locking usually doesn't exist. This patch introduces new genhd flag which controls the auto-blocking behavior and uses it to enable auto-blocking only on optical devices.

2011-04-21block: rescan partitions on invalidated devices on -ENOMEDIA tooTejun Heo
__blkdev_get() doesn't rescan partitions if disk->fops->open() fails, which leads to ghost partition devices lingering after medimum removal is known to both the kernel and userland. The behavior also creates a subtle inconsistency where O_NONBLOCK open, which doesn't fail even if there's no medium, clears the ghots partitions, which is exploited to work around the problem from userland. Fix it by updating __blkdev_get() to issue partition rescan after -ENOMEDIA too. This was reported in the following bz. https://bugzilla.kernel.org/show_bug.cgi?id=13029 Note for stable: 2.6.38 and later only Cc: stable@kernel.org Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: David Zeuthen <zeuthen@gmail.com> Reported-by: Martin Pitt <martin.pitt@ubuntu.com> Reported-by: Kay Sievers <kay.sievers@vrfy.org> Tested-by: Kay Sievers <kay.sievers@vrfy.org> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
2011-04-21cdrom: always check_disk_change() on openTejun Heo
cdrom_open() called check_disk_change() after the rest of open path succeeded which leads to the following bizarre behavior. * After media change, if the device opened without O_NONBLOCK, open_for_data() naturally fails with -ENOMEDIA and check_disk_change() is never called. The media is known to be gone and the open failure makes it obvious to the userland but device invalidation never happens. * But if the device is opened with O_NONBLOCK, all the checks are bypassed and cdrom_open() doesn't notice that the media is not there and check_disk_change() is called and invalidation happens. There's nothing to be gained by avoiding calling check_disk_change() on open failure. Common cases end up calling check_disk_change() anyway. All we get is inconsistent behavior. Fix it by moving check_disk_change() invocation to the top of cdrom_open() so that it always gets called regardless of how the rest of open proceeds.

2011-04-18proc: do proper range check on readdir offsetLinus Torvalds
Rather than pass in some random truncated offset to the pid-related functions, check that the offset is in range up-front. This is just cleanup, the previous commit fixed the real problem. Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-04-18next_pidmap: fix overflow conditionLinus Torvalds
next_pidmap() just quietly accepted whatever 'last' pid that was passed in, which is not all that safe when one of the users is /proc. Admittedly the proc code should do some sanity checking on the range (and that will be the next commit), but that doesn't mean that the helper functions should just do that pidmap pointer arithmetic without checking the range of its arguments. So clamp 'last' to PID_MAX_LIMIT. The fact that we then do "last+1" doesn't really matter, the for-loop does check against the end of the pidmap array properly (it's only the actual pointer arithmetic overflow case we need to worry about, and going one bit beyond isn't going to overflow).

2011-04-18Input: xen-kbdfront - fix mouse getting stuck after save/restoreIgor Mammedov
Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254.

2011-04-18md: fix up raid1/raid10 unplugging.NeilBrown
We just need to make sure that an unplug event wakes up the md thread, which is exactly what mddev_check_plugged does. Also remove some plug-related code that is no longer needed. Signed-off-by: NeilBrown <neilb@suse.de>
2011-04-18md: incorporate new plugging into raid5.NeilBrown
In raid5 plugging is used for 2 things: 1/ collecting writes that require a bitmap update 2/ collecting writes in the hope that we can create full stripes - or at least more-full. We now release these different sets of stripes when plug_cnt is zero. Also in make_request, we call mddev_check_plug to hopefully increase plug_cnt, and wake up the thread at the end if plugging wasn't achieved for some reason. Signed-off-by: NeilBrown <neilb@suse.de>
2011-04-18md: provide generic support for handling unplug callbacks.NeilBrown
When an md device adds a request to a queue, it can call mddev_check_plugged. If this succeeds then we know that the md thread will be woken up shortly, and ->plug_cnt will be non-zero until then, so some processing can be delayed. If it fails, then no unplug callback is expected and the make_request function needs to do whatever is required to make the request happen. Signed-off-by: NeilBrown <neilb@suse.de>
2011-04-18md - remove old plugging code.NeilBrown
md has some plugging infrastructure for RAID5 to use because the normal plugging infrastructure required a 'request_queue', and when called from dm, RAID5 doesn't have one of those available. This relied on the ->unplug_fn callback which doesn't exist any more. So remove all of that code, both in md and raid5. Subsequent patches with restore the plugging functionality.

2011-04-18md/dm - remove remains of plug_fn callback.NeilBrown

2011-04-18block: drop queue lock before calling __blk_run_queue() for kblockd puntJens Axboe
If we know we are going to punt to kblockd, we can drop the queue lock before calling into __blk_run_queue() since it only does a safe bit test and a workqueue call. Since kblockd needs to grab this very lock as one of the first things it does, it's a good optimization to drop the lock before waking kblockd. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
2011-04-18Revert "block: add callback function for unplug notification"Jens Axboe

2011-04-18powerpc/perf_event: Skip updating kernel counters if register value shrinksEric B Munson
Because of speculative event roll back, it is possible for some event coutners to decrease between reads on POWER7. This causes a problem with the way that counters are updated. Delta calues are calculated in a 64 bit value and the top 32 bits are masked. If the register value has decreased, this leaves us with a very large positive value added to the kernel counters. This patch protects against this by skipping the update if the delta would be negative. This can lead to a lack of precision in the coutner values, but from my testing the value is typcially fewer than 10 samples at a time.

2011-04-18powerpc/pseries: Use a kmem cache for DTL buffersNishanth Aravamudan
PAPR specifies that DTL buffers can not cross AMS environments (aka CMO in the PAPR) and can not cross a memory entitlement granule boundary (4k). This is found in section 14.11.3.2 H_REGISTER_VPA of the PAPR. kmalloc does not guarantee an alignment of the allocation, though, beyond 8 bytes (at least in my understanding).

2011-04-17i2c-algo-bit: Call pre/post_xfer for bit_testAlex Deucher
Apparently some distros set i2c-algo-bit.bit_test to 1 by default. In some cases this causes i2c_bit_add_bus to fail and prevents the i2c bus from being added. In the radeon case, we fail to add the ddc i2c buses which prevents the driver from being able to detect attached monitors. The i2c bus works fine even if bit_test fails. This is likely due to gpio switching that is required and handled in the pre/post_xfer hooks, so call the pre/post_xfer hooks in the bit test as well.
