Greg Kroah-Hartman 2c1cf00eea relay: check return of create_buf_file() properly ... If create_buf_file() returns an error, don't try to reference it later as a valid dentry pointer. This problem was exposed when debugfs started to return errors instead of just NULL for some calls when they do not succeed properly. Also, the check for WARN_ON(dentry) was just wrong :) Reported-by: Kees Cook <keescook@chromium.org> Reported-and-tested-by: syzbot+16c3a70e1e9b29346c43@syzkaller.appspotmail.com Reported-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: David Rientjes <rientjes@google.com> Fixes: ff9fb72bc0 ("debugfs: return error values, not NULL") Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2019-01-31 14:01:48 +01:00
