Subject: [PATCH 6.1 006/118] btrfs: lock the inode in shared mode before starting fiemap
Date: Mon, 20 Feb 2023 14:35:22 +0100 [thread overview]
Message-ID: <20230220133600.646294275@linuxfoundation.org> (raw)
In-Reply-To: <20230220133600.368809650@linuxfoundation.org>
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit 519b7e13b5ae8dd38da1e52275705343be6bb508 ]
Currently fiemap does not take the inode's lock (VFS lock), it only locks
a file range in the inode's io tree. This however can lead to a deadlock
if we have a concurrent fsync on the file and fiemap code triggers a fault
when accessing the user space buffer with fiemap_fill_next_extent(). The
deadlock happens on the inode's i_mmap_lock semaphore, which is taken both
by fsync and btrfs_page_mkwrite(). This deadlock was recently reported by
syzbot and triggers a trace like the following:

What happens is the following:
1) Task A is doing an fsync, enters btrfs_sync_file() and flushes delalloc
before locking the inode and the i_mmap_lock semaphore, that is, before
calling btrfs_inode_lock();
2) After task A flushes delalloc and before it calls btrfs_inode_lock(),
another task dirties a page;
3) Task B starts a fiemap without FIEMAP_FLAG_SYNC, so the page dirtied
at step 2 remains dirty and unflushed. Then when it enters
extent_fiemap() and it locks a file range that includes the range of
the page dirtied in step 2;
4) Task A calls btrfs_inode_lock() and locks the inode (VFS lock) and the
inode's i_mmap_lock semaphore in write mode. Then it tries to flush
delalloc by calling start_ordered_ops(), which will block, at
find_lock_delalloc_range(), when trying to lock the range of the page
dirtied at step 2, since this range was locked by the fiemap task (at
step 3);
5) Task B generates a page fault when accessing the user space fiemap
buffer with a call to fiemap_fill_next_extent().
The fault handler needs to call btrfs_page_mkwrite() for some other
page of our inode, and there we deadlock when trying to lock the
inode's i_mmap_lock semaphore in read mode, since the fsync task locked
it in write mode (step 4) and the fsync task can not progress because
it's waiting to lock a file range that is currently locked by us (the
fiemap task, step 3).
Fix this by taking the inode's lock (VFS lock) in shared mode when
entering fiemap. This effectively serializes fiemap with fsync (except the
most expensive part of fsync, the log sync), preventing this deadlock.
