| * xfs: don't leak quotacheck dquots when cow recoveryDarrick J. Wong2017-08-17
| | | | | | | | | | | | | | | | | | If we fail a mount on account of cow recovery errors, it's possible that a previous quotacheck left some dquots in memory. The bailout clause of xfs_mountfs forgets to purge these, and so we leak them. Fix that. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
| * xfs: clear MS_ACTIVE after finishing log recoveryDarrick J. Wong2017-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Way back when we established inode block-map redo log items, it was discovered that we needed to prevent the VFS from evicting inodes during log recovery because any given inode might be have bmap redo items to replay even if the inode has no link count and is ultimately deleted, and any eviction of an unlinked inode causes the inode to be truncated and freed too early. To make this possible, we set MS_ACTIVE so that inodes would not be torn down immediately upon release. Unfortunately, this also results in the quota inodes not being released at all if a later part of the mount process should fail, because we never reclaim the inodes. So, set MS_ACTIVE right before we do the last part of log recovery and clear it immediately after we finish the log recovery so that everything will be torn down properly if we abort the mount.

| * xfs: fix inobt inode allocation search optimizationOmar Sandoval2017-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we try to allocate a free inode by searching the inobt, we try to find the inode nearest the parent inode by searching chunks both left and right of the chunk containing the parent. As an optimization, we cache the leftmost and rightmost records that we previously searched; if we do another allocation with the same parent inode, we'll pick up the search where it last left off. There's a bug in the case where we found a free inode to the left of the parent's chunk: we need to update the cached left and right records, but because we already reassigned the right record to point to the left, we end up assigning the left record to both the cached left and right records. This isn't a correctness problem strictly, but it can result in the next allocation rechecking chunks unnecessarily or allocating inodes further away from the parent than it needs to. Fix it by swapping the record pointer after we update the cached left and right records.

The result of these malicious bio merges is a bio that extends past the memory page used by any of the originating bios. Take into account the following scenario, where a guest creates two grant references that point to the same mfn, ie: grant 1 -> mfn A, grant 2 -> mfn A. These references are then used in a PV block request, and mapped by the backend domain, thus obtaining two different pfns that point to the same mfn, pfn B -> mfn A, pfn C -> mfn A. If those grants happen to be used in two consecutive sectors of a disk IO operation becoming two different bios in the backend domain, the checks in xen_biovec_phys_mergeable will succeed, because bfn1 == bfn2 (they both point to the same mfn). However due to the bio merging, the backend domain will end up with a bio that expands past mfn A into mfn A + 1. Fix this by making sure the check in xen_biovec_phys_mergeable takes into account the offset and the length of the bio, this basically replicates whats done in __BIOVEC_PHYS_MERGEABLE using mfns (bus addresses). While there also remove the usage of __BIOVEC_PHYS_MERGEABLE, since that's already checked by the callers of xen_biovec_phys_mergeable. CC: stable@vger.kernel.org Reported-by: "Jan H.

This creates a 1:1 mapping between the addresses used by tscadc and those in its child nodes (adc, tsc). Without such a mapping, the reg = ... lines in the tsc and adc nodes do not create a resource. Probing the fsl-imx25-tcq and fsl-imx25-tsadc drivers will then fail since there's no IORESOURCE_MEM.

This leads to a list double add (without list debugging the kernel hangs due to the double add later): WARNING: CPU: 0 PID: 19 at lib/list_debug.c:31 __list_add_valid+0xbc/0xc4 list_add double add: new=c1229754, prev=c12383b4, next=c1229754. Initialize the power domain after we get the regulator. Also do not print an error in case the regulator defers probing.
