Trying to characterise some performance stuff, I thought I'd run socat
under OSv however it panics:
$ sudo scripts/run.py -n -e 'socat tcp4-listen:6971 open:/dev/null'OSv
v0.55.0
eth0: 192.168.122.76
Booted up in 3245.70 ms
Cmdline: socat tcp4-listen:6971 open:/dev/null
Assertion failed: type == SOCK_STREAM (libc/af_local.cc:
socketpair_af_local: 101)
[backtrace]
0x00000000402228ae <abort(char const*, ...)+280>
0x0000000040222917 <__assert_fail+64>

0x657473696c2d346f <???+1814901871>
The particular function in socat which triggers this is:
static int diag_sock_pair(void) {
int handlersocks[2];
if (socketpair(AF_UNIX, SOCK_DGRAM, 0, handlersocks) < 0) {
diag_sock_send = -1;
diag_sock_recv = -1;
return -1;
}
diag_sock_send = handlersocks[1];
diag_sock_recv = handlersocks[0];
return 0;
}
And in OSv:
#5 0x00000000406fb1d1 in socketpair_af_local (type=2, proto=0,
sv=0x200000700b20) at libc/af_local.cc:101
101 assert(type == SOCK_STREAM);
Not sure why this restriction exists, and I've changed my local socat
to use SOCK_STREAM - but just thought we should note a difference
between linux and OSv here...
