I did:
$ glimpse -H /usr/src/ log_in_vain
/usr/src/sys/netinet/tcp_input.c: static int log_in_vain = 0;
/usr/src/sys/netinet/tcp_input.c: SYSCTL_INT(_net_inet_tcp, OID_AUTO, log_in_vain, CTLFLAG_RW,
/usr/src/sys/netinet/tcp_input.c: &log_in_vain, 0, "");
/usr/src/sys/netinet/tcp_input.c: if (log_in_vain && tiflags & TH_SYN) {
/usr/src/sys/netinet/udp_usrreq.c: static int log_in_vain = 0;
/usr/src/sys/netinet/udp_usrreq.c: SYSCTL_INT(_net_inet_udp, OID_AUTO, log_in_vain, CTLFLAG_RW,
/usr/src/sys/netinet/udp_usrreq.c: &log_in_vain, 0, "");
/usr/src/sys/netinet/udp_usrreq.c: if (log_in_vain) {
As you can see, the sysctl doc strings are empty.
