If I want to use mtx_unlock for some threads, should I use mtx_lock()
before?


I admit, I don't understand your question, but anyway:
man 9 mutex

Looks like a good example why it is a bad idea to have an application 
proxy running in the kernel.  More to the point, could you provide fin 
in frames 8 through 12 and the local variables in frame 8, too?

Re: sendto() giving EPERM outside a jail

Hi,
I am trying to port miniupnpd (http://miniupnp.tuxfamily.org/) and by in large 
it seems to work fine (evil idea as it is :) However it spews out a lot of..
miniupnpd[13010]: sendto(udp_notify): Operation not permitted

According to my reading of the man page it is not possible to get this error 
unless I'm using jails (which I'm not). The code in question does..

That's probably a buglet in the man page.

memset(sockname, 0, sizeof(struct sockaddr_in));
sockname.sin_family = AF_INET;
sockname.sin_port = htons(PORT);
sockname.sin_addr.s_addr = inet_addr(UPNP_MCAST_ADDR);
while(known_service_types[i])
{
snprintf(bufr, sizeof(bufr),
 NOTIFY * HTTP/1.1\r\n
HOST:%s:%d\r\n
...
n = sendto(s, bufr, strlen(bufr), 0,
(struct sockaddr *)sockname, sizeof(struct sockaddr_in) );

(line 278 of miniupnpd.c).

Can someone shed light on what the problem is? The application appears to work 
fine even with this error though.

man setsockopt, search for SO_BROADCAST.
