It can happen that ext3_free_branches calls ext3_forget() for an indirect block in an earlier transaction than a transaction in which we clear pointer to this indirect block. Thus if we crash before a transaction clearing the block pointer is committed, we will see indirect block pointing to already freed blocks and complain during orphan list cleanup. The fix is simple: Make sure ext3_forget() is called in the transaction doing block pointer clearing. This is a backport of an ext4 fix by Amir G. <amir73il@users.sourceforge.net> Signed-off-by: NJan Kara <jack@suse.cz>

The hibernate issues that got fixed in commit 985b823b ("drm/i915: fix hibernation since i915 self-reclaim fixes") turn out to have been incomplete. Vefa Bicakci tested lots of hibernate cycles, and without the __GFP_RECLAIMABLE flag the system eventually fails to resume. With the flag added, Vefa can apparently hibernate forever (or until he gets bored running his automated scripts, whichever comes first). The reclaimable flag was there originally, and was one of the flags that were dropped (unintentionally) by commit 4bdadb97 ("drm/i915: Selectively enable self-reclaim") that introduced all these problems, but I didn't want to just blindly add back all the flags in commit 985b823b, and it looked like __GFP_RECLAIM wasn't necessary. It clearly was. I still suspect that there is some subtle reason we're missing that causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use in this context, and is what the code historically used. And we have no idea what the causes the corruption without it. Reported-and-tested-by: NM.

If we fail to assign resources to a PCI BAR, this patch makes us try the original address from BIOS rather than leaving it disabled. Linux tries to make sure all PCI device BARs are inside the upstream PCI host bridge or P2P bridge apertures, reassigning BARs if necessary. Windows does similar reassignment. Before this patch, if we could not move a BAR into an aperture, we left the resource unassigned, i.e., at address zero. Windows leaves such BARs at the original BIOS addresses, and this patch makes Linux do the same. This is a bit ugly because we disable the resource long before we try to reassign it, so we have to keep track of the BIOS BAR address somewhere. For lack of a better place, I put it in the struct pci_dev. I think it would be cleaner to attempt the assignment immediately when the claim fails, so we could easily remember the original address. But we currently claim motherboard resources in the middle, after attempting to claim PCI resources and before assigning new PCI resources, and changing that is a fairly big job.

OCFS2 uses t_commit trigger to compute and store checksum of the just committed blocks. When a buffer has b_frozen_data, checksum is computed for it instead of b_data but this can result in an old checksum being written to the filesystem in the following scenario: 1) transaction1 is opened 2) handle1 is opened 3) journal_access(handle1, bh) - This sets jh->b_transaction to transaction1 4) modify(bh) 5) journal_dirty(handle1, bh) 6) handle1 is closed 7) start committing transaction1, opening transaction2 8) handle2 is opened 9) journal_access(handle2, bh) - This copies off b_frozen_data to make it safe for transaction1 to commit. jh->b_next_transaction is set to transaction2. 10) jbd2_journal_write_metadata() checksums b_frozen_data 11) the journal correctly writes b_frozen_data to the disk journal 12) handle2 is closed - There was no dirty call for the bh on handle2, so it is never queued for any more journal operation 13) Checkpointing finally happens, and it just spools the bh via normal buffer writeback. This will write b_data, which was never triggered on and thus contains a wrong (old) checksum. This patch fixes the problem by calling the trigger at the moment data is frozen for journal commit - i.e., either when b_frozen_data is created by do_get_write_access or just before we write a buffer to the log if b_frozen_data does not exist. We also rename the trigger to t_frozen as that better describes when it is called.

This patch fixes a kernel Oops in the GFS2 rename code. The problem was in the way the gfs2 directory code was trying to re-use sentinel directory entries. In the failing case, gfs2's rename function was renaming a file to another name that had the same non-trivial length. The file being renamed happened to be the first directory entry on the leaf block. First, the rename code (gfs2_rename in ops_inode.c) found the original directory entry and decided it could do its job by simply replacing the directory entry with another. Therefore it determined correctly that no block allocations were needed. Next, the rename code deleted the old directory entry prior to replacing it with the new name. Therefore, the soon-to-be replaced directory entry was temporarily made into a directory entry "sentinel" or a place holder at the start of a leaf block. Lastly, it went to re-add the replacement directory entry in that leaf block. However, when gfs2_dirent_find_space was looking for space in the leaf block, it used the wrong value for the sentinel. That threw off its calculations so later it decides it can't really re-use the sentinel and therefore must allocate a new leaf block. But because it previously decided to re-use the directory entry, it didn't waste the time to grab a new block allocation for the inode. Therefore, the inode's i_alloc pointer was still NULL and it crashes trying to reference it. In the case of sentinel directory entries, the entire dirent is reused, not just the "free space" portion of it, and therefore the function gfs2_dirent_find_space should use the value 0 rather than GFS2_DIRENT_SIZE(0) for the actual dirent size. Fixing this calculation enables the reproducer programs to work properly. Signed-off-by: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch fixes a problem in an error path when looking up dinodes. There are two sister-functions, gfs2_inode_lookup and gfs2_process_unlinked_inode. Both functions acquire and hold the i_iopen glock for the dinode being looked up. The last thing they try to do is hold the i_gl glock for the dinode. If that glock fails for some reason, the error path was incorrectly calling gfs2_glock_put for the i_iopen glock twice. This resulted in the glock being prematurely freed. The "minimum hold time" usually kept the glock in memory, but the lock interface to dlm (aka lock_dlm) freed its memory for the glock. In some circumstances, it would cause dlm's dlm_astd daemon to try to call the bast function for the freed lock_dlm memory, which resulted in a NULL pointer dereference.

This patch fixes bugzilla bug #590878: GFS2: recovery stuck on transaction lock. We set the frozen flag on the glock when we receive a completion that cannot be delivered due to blocked locks. At that point we check to see whether the first waiting holder has the noexp flag set. If the noexp lock is queued later, then we need to unfreeze the glock at that point in time, namely, in the glock work function. This patch was originally written by Steve Whitehouse, but since he's on holiday, I'm submitting it. It's been well tested with a complex recovery test called revolver.
