GFS2: inline function gfs2_set_mode

2014-03-19T15:53:52Z

Here is a revised patch based on Steve's feedback: This patch eliminates function gfs2_set_mode which was only called in one place, and always returned 0. Signed-off-by: Bob Peterson Signed-off-by: Steven Whitehouse

GFS2: Increase the max number of ACLs

2014-03-19T15:16:24Z

This patch increases the maximum number of ACLs from 25 to 300 for a 4K block size. The value is adjusted accordingly if the block size is smaller. Note that this is an arbitrary limit with a performance tradeoff, and that the physical limit is slightly over 500. Signed-off-by: Bob Peterson Signed-off-by: Steven Whitehouse

GFS2: return -E2BIG if hit the maximum limits of ACLs

2014-03-06T10:39:32Z

Return -E2BIG rather than -EINVAL if hit the maximum size limits of ACLs, as the former errno is consistent with VFS xattr syscalls.

gfs2: use generic posix ACL infrastructure

2014-01-26T04:58:22Z

This contains some major refactoring for the create path so that inodes are created with the right mode to start with instead of fixing it up later. Signed-off-by: Christoph Hellwig 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

gfs2: Use uid_eq and gid_eq where appropriate

2013-02-13T14:15:10Z

Where kuid_t values are compared use uid_eq and where kgid_t values are compared use gid_eq. This is unfortunately necessary because of the type safety that keeps someone from accidentally mixing kuids and kgids with other types. Cc: Steven Whitehouse Signed-off-by: "Eric W. Biederman"

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.

GFS2: Fix sgid propagation when using ACLs

2012-05-04T13:33:06Z

This cleans up the mode setting code when creating inodes. The SGID bit was being reset by setattr_copy() when the user creating a subdirectory was not in the owning group. When ACLs are in use this SGID bit should have been propagated if the ACL allows creation of a subdirectory. GFS2's behaviour now matches that of the other ACL supporting filesystems in this regard.

GFS2: We only need one ACL getting function

2011-11-23T13:31:51Z

There is no need to have two versions of this function with slightly different arguments. Signed-off-by: Steven Whitehouse
