2.2.15 kernel bug report
I am enclosing a section of code that crashes the 2.2.15 kernel repeatedly. My system is a 266 Intel P2 with 128Mb ram. The crash is caused by the connect statement. It does not crash if the socket is in BLOCKING mode. My distribution is Slack 7.0 if that matters.

soval=fcntl(s,F_GETFL,0);
ioval=fcntl(0,F_GETFL,0); fcntl(s,F_SETFL,soval|O_NONBLOCK); fcntl(0,F_SETFL,ioval|O_NONBLOCK);
cwait=WAITCONNECT;
*chin=0;
do{
/*If the following line is commented out the program does not crash*/
rval=connect(s, (struct sockaddr *)&dst, sizeof(dst)); read(0,chin,16); sleep(1); } while((rval) && --cwait && *chin!=0xa);
fcntl(s,F_SETFL,soval&~O_NONBLOCK);fcntl(0,F_SETFL,ioval&~O_NONBLOCK);

You haven't mentioned dst before this line, or s. Make a small, complete, minimal test program that shows the bug.

Hi
this was a bug in 2.2.15 you could do while(1) { connect() }
and it would crash the kernel it was fixed by 2.2.16
