jfs: set i_ctime when setting ACL

2014-02-13T21:56:05Z

This fixes a regression in 3.14-rc1 where xfstests generic/307 fails. jfs sets the ctime on the inode when writing an xattr. Previously, jfs went ahead and stored an acl that can be completely represented in the traditional permission bits, so the ctime was always set in the xattr code. The new code doesn't bother storing the acl in that case, thus the ctime isn't getting set. Signed-off-by: Dave Kleikamp Reported-by: Michael L. Semon

jfs: use generic posix ACL infrastructure

2014-01-26T04:58:22Z

Copy the scheme I introduced to btrfs many years ago to only use the xattr handler for ACLs, but pass plain attrs straight through. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Kleikamp Signed-off-by: Al Viro

fs: make posix_acl_create more useful

2014-01-26T04:58:18Z

Rename the current posix_acl_created to __posix_acl_create and add a fully featured helper to set up the ACLs on file creation that uses get_acl(). Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Signed-off-by: Al Viro

fs: make posix_acl_chmod more useful

2014-01-26T04:58:18Z

Rename the current posix_acl_chmod to __posix_acl_chmod and add a fully featured ACL chmod helper that uses the ->set_acl inode operation. Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Signed-off-by: Al Viro

userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr

2012-09-18T08:01:35Z

- Pass the user namespace the uid and gid values in the xattr are stored in into posix_acl_from_xattr. - Pass the user namespace kuid and kgid values should be converted into when storing uid and gid values in an xattr in posix_acl_to_xattr. - Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to pass in &init_user_ns. In the short term this change is not strictly needed but it makes the code clearer. In the longer term this change is necessary to be able to mount filesystems outside of the initial user namespace that natively store posix acls in the linux xattr format.

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

kill boilerplates around posix_acl_create_masq()

2011-07-25T18:27:32Z

new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with modified clone, on failure releases acl and replaces with NULL. Returns 0 or -ve on error. All callers of posix_acl_create_masq() switched. Signed-off-by: Al Viro

kill boilerplate around posix_acl_chmod_masq()

2011-07-25T18:27:30Z

new helper: posix_acl_chmod(&acl, gfp, mode). Replaces acl with modified clone or with NULL if that has failed; returns 0 or -ve on error. All callers of posix_acl_chmod_masq() switched to that - they'd been doing exactly the same thing. Signed-off-by: Al Viro

vfs: move ACL cache lookup into generic code

2011-07-25T18:23:39Z

This moves logic for checking the cached ACL values from low-level filesystems into generic code. The end result is a streamlined ACL check that doesn't need to load the inode->i_op->check_acl pointer at all for the common cached case. The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.
