I gave misc.c a quick skim before looking into the kernel:
int
unix_listener(const char *path, int backlog, int unlink_first)
{
struct sockaddr_un sunaddr;
int saved_errno, sock;
memset(&sunaddr, 0, sizeof(sunaddr));
sunaddr.sun_family = AF_UNIX;
if (strlcpy(sunaddr.sun_path, path, sizeof(sunaddr.sun_path)) >=
sizeof(sunaddr.sun_path)) {
error("%s: \"%s\" too long for Unix domain socket", __func__,
path);
errno = ENAMETOOLONG;
return -1;
}
sock = socket(PF_UNIX, SOCK_STREAM, 0);
...
if (bind(sock, (struct sockaddr *)&sunaddr, sizeof(sunaddr)) < 0) {
They memset 0 the struct, and pass the size of the struct. So I suspect OpenSSH
is fine.
Thanks
