fs: take the ACL checks to common code

2011-07-25T18:30:23Z

Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

ext2: Fix link count corruption under heavy link+rename load

2011-03-02T10:03:52Z

vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt it as reported and analyzed by Josh. In fact, there is no good reason to mess with i_nlink of the moved file. We did it presumably to simulate linking into the new directory and unlinking from an old one. But the practical effect of this is disputable because fsck can possibly treat file as being properly linked into both directories without writing any error which is confusing. So we just stop increment-decrement games with i_nlink which also fixes the corruption. CC: stable@kernel.org CC: Al Viro Signed-off-by: Josh Hunt Signed-off-by: Jan Kara

fs/vfs/security: pass last path component to LSM on inode creation

2011-02-01T16:12:29Z

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

ext2: Remove redundant unlikely()

2011-01-10T18:04:07Z

IS_ERR() already implies unlikely(), so it can be omitted here. Signed-off-by: Tobias Klauser Signed-off-by: Jan Kara

new helper: ihold()

2010-10-26T01:26:11Z

Clones an existing reference to inode; caller must already hold one. Signed-off-by: Al Viro

dquot: cleanup dquot initialize routine

2010-03-04T23:20:30Z

Get rid of the initialize dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_initialize helper to __dquot_initialize and vfs_dq_init to dquot_initialize to have a consistent namespace.

dquot: move dquot initialization responsibility into the filesystem

2010-03-04T23:20:30Z

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 Signed-off-by: Jan Kara

ext2: fix format string compile warning (ino_t)

2009-09-23T14:39:58Z

Unlike on most other architectures ino_t is an unsigned int on s390. So add an explicit cast to avoid this compile warning: fs/ext2/namei.c: In function 'ext2_lookup': fs/ext2/namei.c:73: warning: format '%lu' expects type 'long unsigned int', but argument 4 has type 'ino_t' Signed-off-by: Heiko Carstens Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
