There's an enhancement to syslogd(8).
Added -M option that limit maximum length of forwarded message.
Initially syslogd had forwarded 1024-bytes messages (RFC 3164). But after [[ https://reviews.freebsd.org/D15011 | D15011 ]] forwarded messages has been truncated to 480 octets (for IPv4).
The patch allows to truncate messages by -M option (default 1024).
MAXLINE constant has been increased up to 8192 octets, corresponded to [[ https://reviews.freebsd.org/D27205 | D27205 ]].
