From c871b0f2fd27e7f9097d507f47de5270f88003b9 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Mon, 6 Jun 2016 12:01:23 -0700 Subject: Btrfs: check if extent buffer is aligned to sectorsize Thanks to fuzz testing, we can pass an invalid bytenr to extent buffer via alloc_extent_buffer(). An unaligned eb can have more pages than it should have, which ends up extent buffer's leak or some corrupted content in extent buffer. This adds a warning to let us quickly know what was happening. Now that alloc_extent_buffer() no more returns NULL, this changes its caller and callers of its caller to match with the new error handling.

But we're returning NULL in both cases, this makes it return -ENOENT in case a) and return -EIO in case b), and this fixes its callers as well as btrfs_search_forward() 's caller to catch the new errors. The problem is reported by Peter Becker, and I can manage to hit the same BUG_ON by mounting my fuzz image.

However this turned out to had a significant impact on throughput (and a bit on latency too) for benchmarks using the dbench tool, which simulates real workloads from smbd (Samba) servers. For example on a test vm (with a debug kernel): Unpatched: Throughput 19.1572 MB/sec 32 clients 32 procs max_latency=1005.229 ms Patched: Throughput 23.7015 MB/sec 32 clients 32 procs max_latency=809.206 ms The patched results (this patch is applied) are similar to the results of a kernel with the commit 56f23fdbb600 ("Btrfs: fix file/data loss caused by fsync after rename and new inode") reverted. This change avoids the fallback to a transaction commit and instead makes sure all the names of the conflicting inode (the one that had a name in a past transaction that matches the name of the new file in the same parent directory) are logged so that at log replay time we don't lose neither the new file nor the old file, and the old file gets the name it was renamed to. This also ends up avoiding a full transaction commit for a similar case that involves an unlink instead of a rename of the old file: at transaction N create file A at directory D at transaction N + M (where M >= 1) remove file A create a new file named A at directory D fsync the new file power fail Signed-off-by: Filipe Manana --- fs/btrfs/inode.c | 19 +++++++++++- fs/btrfs/tree-log.c | 85 ++++++++++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 95 insertions(+), 9 deletions(-) (limited to 'fs/btrfs/tree-log.c') diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c index f9686541997b..453b9d0da5f1 100644 --- a/fs/btrfs/inode.c +++ b/fs/btrfs/inode.c @@ -4203,6 +4203,7 @@ static int btrfs_rmdir(struct inode *dir, struct dentry *dentry) int err = 0; struct btrfs_root *root = BTRFS_I(dir)->root; struct btrfs_trans_handle *trans; + u64 last_unlink_trans; if (inode->i_size > BTRFS_EMPTY_DIR_SIZE) return -ENOTEMPTY; @@ -4225,11 +4226,27 @@ static int btrfs_rmdir(struct inode *dir, struct dentry *dentry) if (err) goto out; + last_unlink_trans = BTRFS_I(inode)->last_unlink_trans; + /* now the directory is empty */ err = btrfs_unlink_inode(trans, root, dir, d_inode(dentry), dentry->d_name.name, dentry->d_name.len); - if (!err) + if (!err) { btrfs_i_size_write(inode, 0); + /* + * Propagate the last_unlink_trans value of the deleted dir to + * its parent directory.

So fix this by ensuring that when logging the inode for a new dentry that has a name matching an old name of some other inode, we don't log again the original inode that we are fsync'ing.

It gets added to a per log-transaction list which we walk when things go bad. Commit d1433debe added an optimization to skip waiting for the log commit, but didn't take root_log_ctx out of the list. This patch makes sure we remove things before exiting.
