62456 + This feature supports both IPV4 and IPV6 and exempts the

62459 + visibility against scanners.
62460 +
62461 + The blackhole feature as-implemented is equivalent to the FreeBSD
62462 + blackhole feature, as it prevents RST responses to all packets, not
62463 + just SYNs. Under most application behavior this causes no

62467 + side-effect and to prevent intentional LAST_ACK DoSes, this
62468 + feature also adds automatic mitigation against such attacks.
62469 + The mitigation drastically reduces the amount of time a socket
62470 + can spend in LAST_ACK state. If you're using haproxy and not

109868 + * This plugin recomputes expressions of function arguments marked by a size_overflow attribute
109869 + * with double integer precision (DImode/TImode for 32/64 bit integer types).
109870 + * The recomputed argument is checked against TYPE_MAX and an event is logged on overflow and the triggering process is killed.
109871 + *
