Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

udf: Fix crash after seekdir udf_readdir() didn't validate the directory position it should start reading from. Thus when user uses lseek(2) on directory file descriptor it can trick udf_readdir() into reading from a position in the middle of directory entry which then upsets directory parsing code resulting in errors or even possible kernel crashes. Similarly when the directory is modified between two readdir calls, the directory position need not be valid anymore. Add code to validate current offset in the directory. This is actually rather expensive for UDF as we need to read from the beginning of the directory and parse all directory entries. This is because in UDF a directory is just a stream of data containing directory entries and since file names are fully under user's control we cannot depend on detecting magic numbers and checksums in the header of directory entry as a malicious attacker could fake them. We skip this step if we detect that nothing changed since the last readdir call. Reported-by: Nathan Wilson <nate@chickenbrittle.com> CC: stable@vger.kernel.org Signed-off-by: Jan Kara <jack@suse.cz>

rename the generic fsync implementations We don't name our generic fsync implementations very well currently. The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
