This deadlock is 100% reproducible. This is because nilfs_ioctl_change_cpmode() first locks sb->s_umount in read mode and then waits for unfreezing in nilfs_transaction_begin(), whereas thaw_super() locks sb->s_umount in write mode. The locking of sb->s_umount here was intended to make snapshot mounts and the downgrade of snapshots to checkpoints exclusive. This fixes the deadlock issue by replacing the sb->s_umount usage in nilfs_ioctl_change_cpmode() with a dedicated mutex which protects snapshot mounts.

2012-07-30nilfs2: fix timing issue between rmcp and chcp ioctlsRyusuke Konishi1-3/+7
The checkpoint deletion ioctl (rmcp ioctl) has potential for breaking snapshot because it is not fully exclusive with checkpoint mode change ioctl (chcp ioctl). The rmcp ioctl first tests if the specified checkpoint is a snapshot or not within nilfs_cpfile_delete_checkpoint function, and then calls nilfs_cpfile_delete_checkpoints function to actually invalidate the checkpoint only if it's not a snapshot. However, the checkpoint can be changed into a snapshot by the chcp ioctl between these two operations. In that case, calling nilfs_cpfile_delete_checkpoints() wrongly invalidates the snapshot, which leads to snapshot list corruption and snapshot count mismatch. This fixes the issue by changing nilfs_cpfile_delete_checkpoints() so that it reconfirms the target checkpoints are snapshot or not. This second check is exclusive with the chcp operation since it is protected by an existing semaphore.
