'struct proc' member in the struct sockopt can be NULL. As per the comment
in that structure, NULL means that the calling entity is the kernel, not a
user process (my interpretation):
struct sockopt {
enum sopt_dir sopt_dir; /* is this a get or a set? */
int sopt_level; /* second arg of [gs]etsockopt */
int sopt_name; /* third arg of [gs]etsockopt */
void *sopt_val; /* fourth arg of [gs]etsockopt */
size_t sopt_valsize; /* (almost) fifth arg of [gs]etsockopt */
struct proc *sopt_p; /* calling process or null if kernel */
};
This doesn't apply to socreate() since it isn't passed a 'struct sockopt'
as argument. From a quick glance, the socket functions that are concerned
are sosetopt() and sogetopt().

I will test the NGM_KSOCKET_GETOPT code path as I suspect that a similar
fix will be required.
