2012-10-25Btrfs: fix memory leak when cloning root's nodeLiu Bo1-3/+5
After cloning root's node, we forgot to dec the src's ref which can lead to a memory leak. Signed-off-by: Liu Bo <[email protected]> Signed-off-by: Chris Mason <[email protected]>

2012-10-25Btrfs: Use btrfs_update_inode_fallback when creating a snapshotJosef Bacik3-5/+6
On a really full file system I was getting ENOSPC back from btrfs_update_inode when trying to update the parent inode when creating a snapshot. Just use the fallback method so we can update the inode and not have to worry about having a delayed ref. Thanks, Signed-off-by: Josef Bacik <[email protected]>

2012-10-25Btrfs: fix deadlock caused by the nested chunk allocationMiao Xie1-0/+7
Steps to reproduce: # mkfs.btrfs -m raid1 <disk1> <disk2> # btrfstune -S 1 <disk1> # mount <disk1> <mnt> # btrfs device add <disk3> <disk4> <mnt> # mount -o remount,rw <mnt> # dd if=/dev/zero of=<mnt>/tmpfile bs=1M count=1 Deadlock happened. It is because of the nested chunk allocation. When we wrote the data into the filesystem, we would allocate the data chunk because there was no data chunk in the filesystem. At the end of the data chunk allocation, we should insert the metadata of the data chunk into the extent tree, but there was no raid1 chunk, so we tried to lock the chunk allocation mutex to allocate the new chunk, but we had held the mutex, the deadlock happened. By rights, we would allocate the raid1 chunk when we added the second device because the profile of the seed filesystem is raid1 and we had two devices. But we didn't do that in fact. It is because the last step of the first device insertion didn't commit the transaction. So when we added the second device, we didn't cow the tree, and just inserted the relative metadata into the leaves which were generated by the first device insertion, and its profile was dup. So, I fix this problem by commiting the transaction at the end of the first device insertion. Signed-off-by: Miao Xie <[email protected]>

2012-10-25Fix a sign bug causing invalid memory access in the ino_paths ioctl.Gabriel de Perthuis1-1/+1
To see the problem, create many hardlinks to the same file (120 should do it), then look up paths by inode with: ls -i btrfs inspect inode-resolve -v $ino /mnt/btrfs I noticed the memory layout of the fspath->val data had some irregularities (some unnecessary gaps that stop appearing about halfway), so I'm not sure there aren't any bugs left in it.

2012-10-25USB: mos7840: fix port-data memory leakJohan Hovold1-130/+89
Fix port-data memory leak by moving port data allocation and deallocation to port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Note that the indentation was kept intact using a do-while(0) in order to facilitate review. A follow-up patch will remove it. Compile-only tested.

2012-10-25x86: efi: Turn off efi_enabled after setup on mixed fw/kernelOlof Johansson3-8/+23
When 32-bit EFI is used with 64-bit kernel (or vice versa), turn off efi_enabled once setup is done. Beyond setup, it is normally used to determine if runtime services are available and we will have none. This will resolve issues stemming from efivars modprobe panicking on a 32/64-bit setup, as well as some reboot issues on similar setups.

2012-10-25USB: usb-wwan: fix multiple memory leaks in error pathsJohan Hovold5-78/+54
Fix port-data memory leak in usb-serial probe error path by moving port data allocation to port_probe. Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect with a port_remove hook") port data is deallocated in port_remove. This leaves a possibility for memory leaks if usb-serial probe fails after attach but before the port in question has been successfully registered. Note that this patch also fixes two additional memory leaks in the error path of attach should port initialisation fail for any port as the urbs were never freed and neither was the data of any of the successfully initialised ports.

Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer accessible at disconnect or release.

2012-10-25USB: mct_u232: fix broken closeJohan Hovold1-6/+8
Make sure generic close is called at close. The driver relies on the generic write implementation but did not call generic close. Note that the call to kill the read urb is not redundant, as mct_u232 uses an interrupt urb from the second port as the read urb and that generic close therefore fails to kill it.
