This is an IPPROTO_TCP, TCP_NOPUSH with an optval of 0.Hi John,
Can you try making a far simpler program that just does:
int optval, s;
s = socket(PF_INET, SOCK_STREAM, 0);
if (s< 0)
optval = 0;
if (setsockopt(s, IPPROTO_TCP, TCP_NOPUSH,&optval, sizeof(optval))< 0)
and see if that breaks?
I can't repeat this with the code you sent. I tried this in a while (1)
loop and had 4 instances running without issue.
FWIW, I can't crash 7.4-RC2 (i386) and 8.2-RC2 (amd64) with either the original or John's code. Tried both as user and root.
