2013-06-29SELinux: Institute file_path_has_perm()David Howells
Create a file_path_has_perm() function that is like path_has_perm() but instead takes a file struct that is the source of both the path and the inode (rather than getting the inode from the dentry in the path). This is then used where appropriate. This will be useful for situations like unionmount where it will be possible to have an apparently-negative dentry (eg. a fallthrough) that is open with the file struct pointing to an inode on the lower fs.

2013-06-29Replace a bunch of file->dentry->d_inode refs with file_inode()David Howells
Replace a bunch of file->dentry->d_inode refs with file_inode(). In __fput(), use file->f_inode instead so as not to be affected by any tricks that file_inode() might grow. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

In this case we do need a bit more than usual, due to orphan list handling. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

O_TMPFILE | O_CREAT => linkat() with AT_SYMLINK_FOLLOW and /proc/self/fd/<n> as oldpath (i.e. flink()) will create a link O_TMPFILE | O_CREAT | O_EXCL => ENOENT on attempt to link those guys Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
