* Btrfs: fix crash in scrub repair code when device is missingStefan Behrens2012-05-041-0/+7
| | | | | | | | | | Fix that when scrub tries to repair an I/O or checksum error and one of the devices containing the mirror is missing, it crashes in bio_add_page because the bdev is a NULL pointer for missing devices.

* Btrfs: fix page leak when allocing extent buffersJosef Bacik2012-05-041-2/+2
| | | | | | | | | | | | If we happen to alloc a extent buffer and then alloc a page and notice that page is already attached to an extent buffer, we will only unlock it and free our existing eb. Any pages currently attached to that eb will be properly freed, but we don't do the page_cache_release() on the page where we noticed the other extent buffer which can cause us to leak pages and I hope cause the weird issues we've been seeing in this area.

* Btrfs: reduce lock contention during extent insertionChris Mason2012-04-271-2/+7
| | | | | | | | | | | | We're spending huge amounts of time on lock contention during end_io processing because we unconditionally assume we are overwriting an existing extent in the file for each IO. This checks to see if we are outside i_size, and if so, it uses a less expensive readonly search of the btree to look for existing extents. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: avoid deadlocks from GFP_KERNEL allocations during btrfs_real_readdirChris Mason2012-04-271-29/+1
| | | | | | | | | | | | | | Btrfs has an optimization where it will preallocate dentries during readdir to fill in enough information to open the inode without an extra lookup. But, we're calling d_alloc, which is doing GFP_KERNEL allocations, and that leads to deadlocks because our readdir code has tree locks held. For now, disable this optimization. We'll fix the gfp mask in the next merge window. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: fix block_rsv and space_info lock orderingStefan Behrens2012-04-271-2/+2
| | | | | | | | | | | | | | | | | may_commit_transaction() calls spin_lock(&space_info->lock); spin_lock(&delayed_rsv->lock); and update_global_block_rsv() calls spin_lock(&block_rsv->lock); spin_lock(&sinfo->lock); Lockdep complains about this at run time. Everywhere except in update_global_block_rsv(), the space_info lock is the outer lock, therefore the locking order in update_global_block_rsv() is changed.

| | | | | | | | | btrfs_map_block sets mirror_num, so that the repair code knows eventually which device gave us the read error. For RAID10, mirror_num must be 1 or 2.

* Btrfs: do not start delalloc inodes during syncJosef Bacik2012-04-271-1/+0
| | | | | | | | | | | | | btrfs_start_delalloc_inodes will just walk the list of delalloc inodes and start writing them out, but it doesn't splice the list or anything so as long as somebody is doing work on the box you could end up in this section _forever_. So just remove it, it's not needed anyway since sync will start writeback on all inodes anyway, all we need to do is wait for ordered extents and then we can commit the transaction. In my horrible torture test sync goes from taking 4 minutes to about 1.5 minutes. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: fix that check_int_data mount option was ignoredStefan Behrens2012-04-181-1/+1
| | | | | | | | | | The bitfield member mount_opt was too small by one bit to hold the mount option that enabled to include data extents in the integrity checker. Since the same issue happened when the BTRFS_MOUNT_PANIC_ON_FATAL_ERROR option was added (git rebase silently merges so that the increase of the size of the bitfield member is lost), the bit limit was removed entirely.

| | | | | | | | | When a filesystem is mounted with the degraded option, it is possible that some of the devices are not there. btrfs_ioctl_dev_info() crashs in this case because the device name is a NULL pointer.

* btrfs: don't return EINTRArne Jansen2012-04-181-6/+3
| | | | | | | | | | | | It is basically a good thing if we are interruptible when waiting for free space, but the generality in which it is implemented currently leads to system calls being interruptible that are not documented this way. For example git can't handle interrupted unlink(), leading to corrupt repos under space pressure. Instead we raise the bar to only be interruptible by SIGKILL.

* Btrfs: always store the mirror we read the eb fromJosef Bacik2012-04-184-20/+17
| | | | | | | | | | | | A user reported a panic where we were trying to fix a bad mirror but the mirror number we were giving was 0, which is invalid. This is because we don't do the transid verification until after the read, so as far as the read code is concerned the read was a success. So instead store the mirror we read from so that if there is some failure post read we know which mirror to try next and which mirror needs to be fixed if we find a good copy of the block.

* Btrfs: Make free_ipath() deal gracefully with NULL pointersJesper Juhl2012-04-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make free_ipath() behave like most other freeing functions in the kernel and gracefully do nothing when passed a NULL pointer. Besides this making the bahaviour consistent with functions such as kfree(), vfree(), btrfs_free_path() etc etc, it also fixes a real NULL deref issue in fs/btrfs/ioctl.c::btrfs_ioctl_ino_to_path(). In that function we have this code: ... ipath = init_ipath(size, root, path); if (IS_ERR(ipath)) { ret = PTR_ERR(ipath); ipath = NULL; goto out; } ... out: btrfs_free_path(path); free_ipath(ipath); ... If we ever take the true branch of that 'if' statement we'll end up passing a NULL pointer to free_ipath() which will subsequently dereference it and we'll go "Boom" :-( This patch will avoid that.

* Btrfs: use commit root when loading free space cacheJosef Bacik2012-04-132-10/+3
| | | | | | | | | | | | | | A user reported that booting his box up with btrfs root on 3.4 was way slower than on 3.3 because I removed the ideal caching code. It turns out that we don't load the free space cache if we're in a commit for deadlock reasons, but since we're reading the cache and it hasn't changed yet we are safe reading the inode and free space item from the commit root, so do that and remove all of the deadlock checks so we don't unnecessarily skip loading the free space cache.

Meanwhile, invalidate pagecache(*) will fail due to dirty flags in pages. So the old data may be flushed into disk by flush thread, which will lead to data loss.

* Btrfs: flush out and clean up any block device pages during mountChris Mason2012-03-292-0/+4
| | | | | | | | | | | | | | Btrfs puts the filesystem metadata into its own address space, and somehow the block device address space isn't getting onto disk properly before a mount.

This is a short term measure to make sure it is fixed. The block devices really should be flushed and cleaned up higher in the stack. Signed-off-by: Chris Mason <chris.mason@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | In commit 4692cf58 we introduced new backref walking code for btrfs. This assumes we're searching live roots, which requires a transaction context. While scrubbing, however, we must not join a transaction because this could deadlock with the commit path. Additionally, what scrub really wants to do is resolving a logical address in the commit root it's currently checking. This patch adds support for logical to path resolving on commit roots and makes scrub use that. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
