Public bug reported:
On any host platform where SOCK_CLOEXEC is defined (Linux at least), a
socket is leaked on each call to qemu_socket() AND the socket returned
hasn't been created with the desired SOCK_CLOEXEC attribute. The
qemu_socket routine is:
Line 272 of util/osdep.c:
/*
* Opens a socket with FD_CLOEXEC set
*/
int qemu_socket(int domain, int type, int protocol)
{
int ret;
#ifdef SOCK_CLOEXEC
ret = socket(domain, type | SOCK_CLOEXEC, protocol);
if (ret != -1 || errno != EINVAL) {
return ret;
}
#endif
ret = socket(domain, type, protocol);
if (ret >= 0) {
qemu_set_cloexec(ret);
}
return ret;
}
