UDF: support NFSv2 export

2015-05-18T09:23:08+00:00

The "fh_len" passed to ->fh_to_* is not guaranteed to be that same as that returned by encode_fh - it may be larger. With NFSv2, the filehandle is fixed length, so it may appear longer than expected and be zero-padded. So we must test that fh_len is at least some value, not exactly equal to it.

udf: Return error from udf_find_entry()

2015-05-18T09:23:07+00:00

Return appropriate error from udf_find_entry() instead of just NULL. That way we can distinguish the fact that some error happened when looking up filename (and return error to userspace) from the fact that we just didn't find the filename. Also update callers of udf_find_entry() accordingly. [JK: Improved udf_find_entry() documentation] Suggested-by: Jan Kara Signed-off-by: Fabian Frederick Signed-off-by: Jan Kara

udf: Return -ENOMEM when allocation fails in udf_get_filename()

2015-05-18T09:23:03+00:00

Return -ENOMEM when allocation fails in udf_get_filename(). Update udf_pc_to_char(), udf_readdir(), and udf_find_entry() to handle the error appropriately. This allows us to pass appropriate error to userspace instead of corrupting symlink contents by omitting some path elements. Signed-off-by: Fabian Frederick Signed-off-by: Jan Kara

udf: Update ctime and mtime when directory is modified

2015-04-01T12:26:14+00:00

We failed to update ctime & mtime of a directory when new entry was created in it during rename, link, create, etc. Fix that. Reported-by: Taesoo Kim Signed-off-by: Jan Kara

udf: Reduce repeated dereferences

2014-12-21T21:42:37+00:00

Replace repeated dereferences like dir->i_sb by storing superblock pointer in a variable and using that. Signed-off-by: Jan Kara

udf: Check path length when reading symlink

2014-12-19T13:12:08+00:00

Symlink reading code does not check whether the resulting path fits into the page provided by the generic code. This isn't as easy as just checking the symlink size because of various encoding conversions we perform on path. So we have to check whether there is still enough space in the buffer on the fly.
