* Squashfs: add sanity checks to lookup table reading at mount timePhillip Lougher2011-05-253-4/+30
| | | | | | | | | | | | Fsfuzzer generates corrupted filesystems which throw a warn_on in kmalloc. One of these is due to a corrupted superblock inodes field. Fix this by checking that the number of bytes to be read (and allocated) does not extend into the next filesystem structure. Also add a couple of other sanity checks of the mount-time lookup table structures. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>

* Squashfs: handle corruption of directory structurePhillip Lougher2011-03-162-0/+21
| | | | | | | | | | | | | | | | | | Handle the rare case where a directory metadata block is uncompressed and corrupted, leading to a kernel oops in directory scanning (memcpy). Normally corruption is detected at the decompression stage and dealt with then, however, this will not happen if: - metadata isn't compressed (users can optionally request no metadata compression), or - the compressed metadata block was larger than the original, in which case the uncompressed version was used, or - the data was corrupt after decompression This patch fixes this by adding some sanity checks against known maximum values.

* Squashfs: extend decompressor framework to handle compression optionsPhillip Lougher2011-02-288-16/+54
| | | | | | | | | | | | | | | | Extend decompressor framework to handle compression options stored in the filesystem. These options can be used by the relevant decompressor at initialisation time to over-ride defaults. The presence of compression options in the filesystem is indicated by the COMP_OPT filesystem flag. If present the data is read from the filesystem and passed to the decompressor init function. The decompressor init function signature has been extended to take this data. Also update the init function signature in the glib, lzo and xz decompressor wrappers.

| * Btrfs: exclude super blocks when we read in block groupsJosef Bacik2011-02-061-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been resulting in a BUT_ON(ret) after btrfs_reserve_extent in btrfs_cow_file_range. The reason is we don't actually calculate the bytes_super for a block group until we go to cache it, which means that the space_info can hand out reservations for space that it doesn't actually have, and we can run out of data space. This is also a problem if you are using space caching since we don't ever calculate bytes_super for the block groups. So instead everytime we read a block group call exclude_super_stripes, which calculates the bytes_super for the block group so it can be left out of the space_info. Then whenever caching completes we just call free_excluded_extents so that the super excluded extents are freed up. Also if we are unmounting and we hit any block groups that haven't been cached we still need to call free_excluded_extents to make sure things are cleaned up properly.

| * Btrfs: make sure search_bitmap finds something in remove_from_bitmapJosef Bacik2011-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When we're cleaning up the tree log we need to be able to remove free space from the block group. The problem is if that free space spans bitmaps we would not find the space since we're looking for too many bytes. So make sure the amount of bytes we search for is limited to either the number of bytes we want, or the number of bytes left in the bitmap. This was tested by a user who was hitting the BUG() after search_bitmap. With this patch he can now mount his fs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Xfstests 224 will just sit there and spin for ever until eventually we give up flushing delalloc and exit. On my box this took several hours. I could not interrupt this process either, even though we use INTERRUPTIBLE. So do 2 things 1) Keep us from looping over and over again without reclaiming anything 2) If we get interrupted exit the loop I tested this and the test now exits in a reasonable amount of time, and can be interrupted with ctrl+c.

| * Btrfs: use the global block reserve if we cannot reserve spaceJosef Bacik2011-01-281-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We call use_block_rsv right before we make an allocation in order to make sure we have enough space. Now normally people have called btrfs_start_transaction() with the appropriate amount of space that we need, so we just use some of that pre-reserved space and move along happily. The problem is where people use btrfs_join_transaction(), which doesn't actually reserve any space. So we try and reserve space here, but we cannot flush delalloc, so this forces us to return -ENOSPC when in reality we have plenty of space. The most common symptom is seeing a bunch of "couldn't dirty inode" messages in syslog. With xfstests 224 we end up falling back to start_transaction and then doing all the flush delalloc stuff which causes to hang for a very long time. So instead steal from the global reserve, which is what this is meant for anyway. With this patch and the other 2 I have sent xfstests 224 now passes successfully.

| * Btrfs: do not release more reserved bytes to the global_block_rsv than we needJosef Bacik2011-01-281-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we do btrfs_block_rsv_release, if global_block_rsv is not full we will release all the extra bytes to global_block_rsv, even if it's only a little short of the amount of space that we need to reserve. This causes us to starve ourselves of reservable space during the transaction which will force us to shrink delalloc bytes and commit the transaction more often than we should. So instead just add the amount of bytes we need to add to the global reserve so reserved == size, and then add the rest back into the space_info for general use.

For more stable Btrfs, I think that we should reduce BUG_ON(). But, I think that long time is necessary for this. So, I propose this patch as a short-term solution. With this patch: - To more stable Btrfs, the part that should be corrected is clarified. - The panic isn't done by the NULL pointer reference etc. (even if BUG_ON() is increased temporarily) - The error code is returned in the place where the error can be easily returned. As a long-term plan: - BUG_ON() is reduced by using the forced-readonly framework, etc. Signed-off-by: Tsutomu Itoh <t-itoh@jp.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>

This can eg result from a memory allocation failure via the call to btrfs_iget, and thus does not imply that root is different than sub_root. Thus, an IS_ERR check is added to ensure that there is no dereference of inode in this case. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...)
