* ocfs2: should not use le32_add_cpu to set ocfs2_dinode i_flagsJoseph Qi2013-07-041-3/+3

| * fs/vfs/security: pass last path component to LSM on inode creationEric Paris2011-02-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path. This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL. Signed-off-by: Eric Paris <eparis@redhat.com>

The generation number for the parent directory is recorded in the inode_info, which increments every time the lock on the directory is dropped.

* ocfs2: Fix orphan add in ocfs2_create_inode_in_orphanMark Fasheh2010-09-081-20/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ocfs2_create_inode_in_orphan() is used by reflink to create the newly reflinked inode simultaneously in the orphan dir. This allows us to easily handle partially-reflinked files during recovery cleanup. We have a problem though - the orphan dir stringifies inode # to determine a unique name under which the orphan entry dirent can be created. Since ocfs2_create_inode_in_orphan() needs the space allocated in the orphan dir before it can allocate the inode, we currently call into the orphan code: /* * We give the orphan dir the root blkno to fake an orphan name, * and allocate enough space for our insertion. */ status = ocfs2_prepare_orphan_dir(osb, &orphan_dir, osb->root_blkno, orphan_name, &orphan_insert); Using osb->root_blkno might work fine on unindexed directories, but the orphan dir can have an index. When it has that index, the above code fails to allocate the proper index entry. Later, when we try to remove the file from the orphan dir (using the actual inode #), the reflink operation will fail. To fix this, I created a function ocfs2_alloc_orphaned_file() which uses the newly split out orphan and inode alloc code to figure out what the inode block number will be (once allocated) and then prepare the orphan dir from that data.

* dquot: move dquot initialization responsibility into the filesystemChristoph Hellwig2010-03-051-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | Currently various places in the VFS call vfs_dq_init directly. This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the initialization. For most metadata operations this is a straight forward move into the methods, but for truncate and open it's a bit more complicated. For truncate we currently only call vfs_dq_init for the sys_truncate case because open already takes care of it for ftruncate and open(O_TRUNC) - the new code causes an additional vfs_dq_init for those which is harmless. For open the initialization is moved from do_filp_open into the open method, which means it happens slightly earlier now, and only for regular files. The latter is fine because we don't need to initialize it for operations on special files, and we already do it as part of the namespace operations for directories. Add a dquot_file_open helper that filesystems that support generic quotas can use to fill in ->open. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
* dquot: cleanup inode allocation / freeing routinesChristoph Hellwig2010-03-051-21/+9Star
| | | | | | | | | | | | | | Get rid of the alloc_inode and free_inode dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Also get rid of the vfs_dq_alloc/vfs_dq_free wrappers and always call the lowlevel dquot_alloc_inode / dqout_free_inode routines directly, which now lose the number argument which is always 1.

* dquot: cleanup space allocation / freeing routinesChristoph Hellwig2010-03-051-5/+4Star
| | | | | | | | | | | | | | | | Get rid of the alloc_space, free_space, reserve_space, claim_space and release_rsv dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Move shared logic into the common __dquot_alloc_space, dquot_claim_space_nodirty and __dquot_free_space low-level methods, and rationalize the wrappers around it to move as much as possible code into the common block for CONFIG_QUOTA vs not. Also rename all these helpers to be named dquot_* instead of vfs_dq_*. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
