* udf: Add read-only support for 2.50 UDF mediaJan Kara2008-04-171-1/+15
| | | | | | | | | | | | This patch implements parsing of metadata partitions and reading of Metadata File thus allowing to read UDF 2.50 media. Error resilience is implemented through accessing the Metadata Mirror File in case the data the Metadata File cannot be read. The patch is based on the original patch by Sebastian Manciulea <manciuleas@yahoo.com> and Mircea Fedoreanu <mirceaf_spl@yahoo.com>.

* udf: Cleanup anchor block detection.Jan Kara2008-04-171-1/+1
| | | | | | | | | | | | | | UDF anchor block detection is complicated by several things - there are several places where the anchor point can be, some of them relative to the last recorded block which some devices report wrongly. Moreover some devices on some media seem to have 7 spare blocks sectors for every 32 blocks (at least as far as I understand the old code) so we have to count also with that possibility. This patch splits anchor block detection into several functions so that it is clearer what we actually try to do. We fix several bugs of the type "for such and such media, we fail to check block blah" as a result of the cleanup. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: move headers out include/linux/Christoph Hellwig2008-04-171-0/+93
| | | | | | | | | | | | | | | | There's really no reason to keep udf headers in include/linux as they're not used by anything but fs/udf/. This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h, include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and include/linux/udf_fs.h into fs/udf/udfdecl.h. The only thing remaining in include/linux/ is a stub of udf_fs_i.h defining the four user-visible udf ioctls. It's also moved from unifdef-y to headers-y because it can be included unconditionally now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

* UDF: fix UID and GID mount option ignoranceCyrill Gorcunov2007-07-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fix weird behaviour of UDF mounting procedure. To get UID changed (for now) we have to type mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point and specifying two uid at once is strange a bit. So with the patch we are able to mount without additional 'uid=ignore' option. The same for GID option is done. This patch will not break current mount scheme (with two option). Btw this does fix (I hope) the following [BUG 6124] mount of UDF fs ignores UID and GID options http://bugzilla.kernel.org/show_bug.cgi?id=6124 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: Jan Kara <jack@ucw.cz> Cc: Michael <auslands-kv@gmx.de> Cc: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* [PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi2006-03-081-0/+4
| | | | | | | | | | | | | | | | | | | | Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+139
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!
