ocfs2: fix a tiny race when truncate dio orohaned entry

2015-06-25T00:49:39+00:00

Once dio crashed it will leave an entry in orphan dir. And orphan scan will take care of the clean up. There is a tiny race case that the same entry will be truncated twice and then trigger the BUG in ocfs2_del_inode_from_orphan.

ocfs2: use ENOENT instead of EEXIST when get system file fails

2015-04-14T23:48:58+00:00

When ocfs2_get_system_file_inode fails, it is obscure to set the return value to -EEXIST. So change it to -ENOENT. Signed-off-by: Joseph Qi Cc: Mark Fasheh Cc: Joel Becker Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ocfs2: use actual name length when find entry in ocfs2_orphan_del()

2015-04-14T23:48:58+00:00

If the namelen is 20 and name only has actual length 16, it will fail in ocfs2_find_entry because of mismatch. So use actual name length when find entry. Signed-off-by: Joseph Qi Signed-off-by: Yiwen Jiang Cc: Mark Fasheh Cc: Joel Becker Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ocfs2: wait for orphan recovery first once append O_DIRECT write crash

2015-02-17T01:56:05+00:00

If one node has crashed with orphan entry leftover, another node which do append O_DIRECT write to the same file will override the i_dio_orphaned_slot. Then the old entry won't be cleaned forever. If this case happens, we let it wait for orphan recovery first.

ocfs2: add functions to add and remove inode in orphan dir

2015-02-17T01:56:04+00:00

Add functions to add inode to orphan dir and remove inode in orphan dir. Here we do not call ocfs2_prepare_orphan_dir and ocfs2_orphan_add directly. Because append O_DIRECT will add inode to orphan two and may result in more than one orphan entry for the same inode.

ocfs2: fix the wrong directory passed to ocfs2_lookup_ino_from_name() when link file

2015-01-08T23:10:51+00:00

In ocfs2_link(), the parent directory inode passed to function ocfs2_lookup_ino_from_name() is wrong. Parameter dir is the parent of new_dentry not old_dentry. We should get old_dir from old_dentry and lookup old_dentry in old_dir in case another node remove the old dentry. With this change, hard linking works again, when paths are relative with at least one subdirectory. This is how the problem was reproducable: # mkdir a # mkdir b # touch a/test # ln a/test b/test ln: failed to create hard link `b/test' => `a/test': No such file or directory However when creating links in the same dir, it worked well. Now the link gets created.

ocfs2: fix d_splice_alias() return code checking

2014-10-29T23:33:15+00:00

d_splice_alias() can return a valid dentry, NULL or an ERR_PTR. Currently the code checks not for ERR_PTR and will cuase an oops in ocfs2_dentry_attach_lock(). Fix this by using IS_ERR_OR_NULL().
