* reiserfs: fix oops while creating privroot with selinux enabledJeff Mahoney2010-03-24
| | | | | | | | | | | | | | | | | | Commit 57fe60df ("reiserfs: add atomic addition of selinux attributes during inode creation") contains a bug that will cause it to oops when mounting a file system that didn't previously contain extended attributes on a system using security.* xattrs. The issue is that while creating the privroot during mount reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which dereferences the xattr root. The xattr root doesn't exist, so we get an oops.

* reiserfs: fixup perms when xattrs are disabledJeff Mahoney2009-05-17
| | | | | | | | | | This adds CONFIG_REISERFS_FS_XATTR protection from reiserfs_permission. This is needed to avoid warnings during file deletions and chowns with xattrs disabled. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* reiserfs: fixup xattr_root cachingJeff Mahoney2009-05-09
| | | | | | | | | | | | | The xattr_root caching was broken from my previous patch set. It wouldn't cause corruption, but could cause decreased performance due to allocating a larger chunk of the journal (~ 27 blocks) than it would actually use. This patch loads the xattr root dentry at xattr initialization and creates it on-demand. Since we're using the cached dentry, there's no point in keeping lookup_or_create_dir around, so that's removed.

* Always lookup priv_root on reiserfs mount and keep itAl Viro2009-05-09
| | | | | | | | ... even if it's a negative dentry. That way we can set ->d_op on root before anyone could race with us. Simplify d_compare(), while we are at it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* reiserfs: add atomic addition of selinux attributes during inode creationJeff Mahoney2009-03-30
| | | | | | | | | | | | | Some time ago, some changes were made to make security inode attributes be atomically written during inode creation. ReiserFS fell behind in this area, but with the reworking of the xattr code, it's now fairly easy to add. The following patch adds the ability for security attributes to be added automatically during inode creation.

* reiserfs: journaled xattrsJeff Mahoney2009-03-30
| | | | | | | | | | | | | | | | | | | Deadlocks are possible in the xattr code between the journal lock and the xattr sems. This patch implements journalling for xattr operations. The benefit is twofold: * It gets rid of the deadlock possibility by always ensuring that xattr write operations are initiated inside a transaction. * It corrects the problem where xattr backing files aren't considered any differently than normal files, despite the fact they are metadata. I discussed the added journal load with Chris Mason, and we decided that since xattrs (versus other journal activity) is fairly rare, the introduction of larger transactions to support journaled xattrs wouldn't be too big a deal.

* reiserfs: use generic xattr handlersJeff Mahoney2009-03-30
| | | | | | | | | | | | | | | | | | | Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed.

* reiserfs: make per-inode xattr locking more fine grainedJeff Mahoney2009-03-30
| | | | | | | | | | The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level.

* reiserfs: eliminate per-super xattr lockJeff Mahoney2009-03-30

* reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unsetJeff Mahoney2009-03-30
| | | | | | | | | | | | | | The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory.

* reiserfs: remove IS_PRIVATE helpersJeff Mahoney2009-03-30
| | | | | | | | | | There are a number of helper functions for marking a reiserfs inode private that were leftover from reiserfs did its own thing wrt to private inodes. S_PRIVATE has been in the kernel for some time, so this patch removes the helpers and uses IS_PRIVATE instead.

* reiserfs: run scripts/Lindent on reiserfs codeLinus Torvalds2005-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was a pure indentation change, using: scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h to make reiserfs match the regular Linux indentation style. As Jeff Mahoney <jeffm@suse.com> writes: The ReiserFS code is a mix of a number of different coding styles, sometimes different even from line-to-line. Since the code has been relatively stable for quite some time and there are few outstanding patches to be applied, it is time to reformat the code to conform to the Linux style standard outlined in Documentation/CodingStyle. This patch contains the result of running scripts/Lindent against fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the code can be made to look better, but I'd rather keep those patches separate so that there isn't a subtle by-hand hand accident in the middle of a huge patch. To be clear: This patch is reformatting *only*. A number of patches may follow that continue to make the code more consistent with the Linux coding style. Hans wasn't particularly enthusiastic about these patches, but said he wouldn't really oppose them either. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
