bcache: Fix a null ptr deref regression

2013-10-13T23:08:35Z

commit 2fe80d3bbf1c8bd9efc5b8154207c8dd104e7306 upstream. Commit c0f04d88e46d ("bcache: Fix flushes in writeback mode") was fixing a reported data corruption bug, but it seems some last minute refactoring or rebasing introduced a null pointer deref.

net: qmi_wwan: add new Qualcomm devices

2013-10-13T23:08:35Z

commit 0470667caa8261beb8a9141102b04a5357dd45b5 upstream. Adding the device list from the Windows driver description files included with a new Qualcomm MDM9615 based device, "Alcatel-sbell ASB TL131 TDD LTE", from China Mobile. This device is tested and verified to work. The others are assumed to work based on using the same Windows driver. Many of these devices support multiple QMI/wwan ports, requiring multiple interface matching entries. All devices are composite, providing a mix of one or more serial, storage or Android Debug Brigde functions in addition to the wwan function. This device list included an update of one previously known device, which was incorrectly assumed to have a Gobi 2K layout. This is corrected.

HID: uhid: allocate static minor

2013-10-13T23:08:35Z

commit 19872d20c890073c5207d9e02bb8f14d451a11eb upstream. udev has this nice feature of creating "dead" /dev/ device-nodes if it finds a devnode: modalias. Once the node is accessed, the kernel automatically loads the module that provides the node. However, this requires udev to know the major:minor code to use for the node. This feature was introduced by: commit 578454ff7eab61d13a26b568f99a89a2c9edc881 Author: Kay Sievers Date: Thu May 20 18:07:20 2010 +0200 driver core: add devname module aliases to allow module on-demand auto-loading However, uhid uses dynamic minor numbers so this doesn't actually work. We need to load uhid to know which minor it's going to use. Hence, allocate a static minor (just like uinput does) and we're good to go.

Btrfs: remove ourselves from the cluster list under lock

2013-10-13T23:08:34Z

commit b8d0c69b9469ffd33df30fee3e990f2d4aa68a09 upstream. A user was reporting weird warnings from btrfs_put_delayed_ref() and I noticed that we were doing this list_del_init() on our head ref outside of delayed_refs->lock. This is a problem if we have people still on the list, we could end up modifying old pointers and such. Fix this by removing us from the list before we do our run_delayed_ref on our head ref.

Btrfs: skip subvol entries when checking if we've created a dir already

2013-10-13T23:08:34Z

commit a05254143cd183b18002cbba7759a1e4629aa762 upstream. We have logic to see if we've already created a parent directory by check to see if an inode inside of that directory has a lower inode number than the one we are currently processing. The logic is that if there is a lower inode number then we would have had to made sure the directory was created at that previous point. The problem is that subvols inode numbers count from the lowest objectid in the root tree, which may be less than our current progress. So just skip if our dir item key is a root item. This fixes the original test and the xfstest version I made that added an extra subvol create.

Btrfs: change how we queue blocks for backref checking

2013-10-13T23:08:34Z

commit b6c60c8018c4e9beb2f83fc82c09f9d033766571 upstream. Previously we only added blocks to the list to have their backrefs checked if the level of the block is right above the one we are searching for. This is because we want to make sure we don't add the entire path up to the root to the lists to make sure we process things one at a time. This assumes that if any blocks in the path to the root are going to be not checked (shared in other words) then they will be in the level right above the current block on up. This isn't quite right though since we can have blocks higher up the list that are shared because they are attached to a reloc root. But we won't add this block to be checked and then later on we will BUG_ON(!upper->checked). So instead keep track of wether or not we've queued a block to be checked in this current search, and if we haven't go ahead and queue it to be checked. This patch fixed the panic I was seeing where we BUG_ON(!upper->checked). Thanks, Signed-off-by: Josef Bacik Signed-off-by: Chris Mason Signed-off-by: Greg Kroah-Hartman

s390: fix system call restart after inferior call

2013-10-13T23:08:34Z

commit dbbfe487e5f3fc00c9fe5207d63309859704d12f upstream. Git commit 616498813b11ffef "s390: system call path micro optimization" introduced a regression in regard to system call restarting and inferior function calls via the ptrace interface. The pointer to the system call table needs to be loaded in sysc_sigpending if do_signal returns with TIF_SYSCALl set after it restored a system call context.
