2009-12-17Btrfs: Pass transaction handle to security and ACL initialization functionsYan, Zheng
Pass transaction handle down to security and ACL initialization functions, so we can avoid starting nested transactions Signed-off-by: Yan Zheng <zheng.yan@oracle.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2009-02-04Btrfs: selinux supportJim Owens
Add call to LSM security initialization and save resulting security xattr for new inodes. Add xattr support to symlink inode ops. Set inode->i_op for existing special files. Signed-off-by: jim owens <jowens@hp.com>
2008-09-25Btrfs: optimize btrget/set/removexattrChristoph Hellwig
btrfs actually stores the whole xattr name, including the prefix ondisk, so using the generic resolver that strips off the prefix is not very helpful. Instead do the real ondisk xattrs manually and only use the generic resolver for synthetic xattrs like ACLs. (Sorry Josef for guiding you towards the wrong direction here intially) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25btrfs: optmize listxattrChristoph Hellwig
The ->list handler is really not useful at all, because we always call btrfs_xattr_generic_list anyway. After this is done find_btrfs_xattr_handler becomes unused, and it becomes obvious that the temporary name buffer allocation isn't needed but we can directly copy into the supplied buffer. Tested with various getfattr -d calls on varying xattr lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
