Hi Richard,
I mean the change of that two lines to like:
if (cnt < m->header.messageLength || m->header.messageLength <
pdulen) {
pr_debug("wrong length, cnt: %d messageLength: %hu pdulen
:%d",
cnt, m->header.messageLength, pdulen);
return -EBADMSG;
}
Thanks,
vincent

What? We already have
if (cnt < pdulen)
return -EBADMSG;
in msg_post_recv();
Or did you mean something else?
Thanks,
Richard
