| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The evdev buffer isn't big enough when you get many fingers on the device. Bump up the buffer to a reasonable size, matching what other multitouch devices use. Without this change, events may be discarded in the evdev buffer before they are read.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This device contains the very same bug in report descriptor as the Ortek ones do (i.e. LogicalMinimum == 1, which is wrong for the key array). As we have more reports for the Ortek devices, we are keeping the driver name for now. Apparently there is a chip producer which sells chip with this buggy descriptor to multiple vendors. Thus if such reports start to come at highger frequency, we'll either have to rename the driver accordingly, or come up with more generic workaround. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

* | | mm: avoid wrapping vm_pgoff in mremap()Linus Torvalds2011-04-071-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. Noticed by Robert Swiecki when running a system call fuzzer, where it caused a BUG_ON() due to terminally confusing the vma_prio_tree code. A vma dumping patch by Hugh then pinpointed the crazy wrapped case.

To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: Martin K.

* | | | inotify: fix double free/corruption of stuct userEric Paris2011-04-062-26/+14

This is a regression introduced by a2ae4cc9a16e ("inotify: stop kernel memory leak on file creation failure"). We fix this by making sure that if a group exists the user reference is dropped when the group is cleaned up. We should not explictly drop the reference on error and also drop the reference when the group is cleaned up. The new lifetime rules are that an inotify group lives from inotify_new_group to the last fsnotify_put_group. Since the struct user and inotify_devs are directly tied to this lifetime they are only changed/updated in those two locations. We get rid of all special casing of struct user or user->inotify_devs. Signed-off-by: Eric Paris <eparis@redhat.com> Cc: stable@kernel.org (2.6.37 and up) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Following the fix to reset the GMBUS controller after a NAK, we finally utilize the 0xa0 probe for a CRT connection. And discover that the code is broken. Shock. There are a number of issues, but following a key insight from Dave Airlie, that 0xA0 is an invalid address on a 7-bit bus (though not if we were to enable 10-bit addressing), and would look like the EDID port 0x50, it is possible to see where the confusion starts. In short, a write to 0xA0 is accepted by the GMBUS controller which we interpreted as meaning the existence of a connection (a slave on the other end of the wire ACKing the write). That was false. During testing with a broken GMBUS implementation, which never reset an earlier NAK, this test always reported a NAK and so we proceeded on to the next test.

Then commit c2be05481f61252 "powerpc: Fix default_machine_crash_shutdown #ifdef botch" changed the ifdef around the calling site to add a check on SMP, but the ifdef around the function itself was left unchanged, leaving an unused function for PPC_STD_MMU_64=y and SMP=n Rather than have two ifdefs that can get out of sync like this, simply put the corrected conditional around the function and use a stub to get rid of one set of ifdefs completely.

Just remove this warning since it's ok, this will allow all of the normal space accounting take place.

| * | | | | | | Btrfs: fix free space cache when there are pinned extents and clusters V2Josef Bacik2011-04-051-4/+78

Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster and writing out any entries that are in the cluster to the cache, as well as writing any pinned extents we currently have to the cache since those will be available for us to use the next time the fs mounts. This patch also adds a check to the end of load_free_space_cache to make sure we got the right amount of free space cache, and if not make sure to clear the cache and re-cache the old fashioned way.
