unix_mkname() looks like (in both 2.4.x and 2.6.x)...
static int unix_mkname(struct sockaddr_un * sunaddr, int len, unsigned *hashp)
{
if (len <= sizeof(short) || len > sizeof(*sunaddr))
return -EINVAL;
[...]
if (len > sizeof(*sunaddr))
len = sizeof(*sunaddr);
...so if you pass a "large" sockaddr_un struct bind() just returns
-EINVAL. I assume that is intentional, but that just makes the huge
comment and test later dead code.
