... except that it simply confirms that something's fishy with getname_kernel() of ->name of struct filename returned by getname(). IOW, I still do not understand the mechanism of breakage there.
Another thing I really do not understand is + if (inode->i_ino) { + /* valid inode number, use that for the comparison */ + if (n->ino != inode->i_ino || + n->dev != inode->i_sb->s_dev) + continue; in __audit_inode(). We don't *have* dentries with dentry->d_inode->i_ino == 0. Ever. WTF is that about? Paul?
