Re: syslogd truncating messages on FreeBSD >11.2-R

Hi,
please let me know if there is a better forum for this.
As of 11.3-RELEASE syslogd truncates all forwarded messages to 480 bytes for
IPV4 and 1180 for IPv6.
The change occurs in the added code:
switch (f->f_type) {
case F_FORW:
/* Truncate messages to RFC 5426 recommended size. */
dprintf(" %s", f->fu_forw_hname);
switch (f->fu_forw_addr->ai_addr->sa_family) {
#ifdef INET
case AF_INET:
dprintf(":%d\n",
ntohs(satosin(f->fu_forw_addr->ai_addr)->sin_port));
iovlist_truncate(il, 480);
break;
#endif
There's more code for IPv6 and the function iovlist_truncate itself.
This change is not turned on by a switch and happens automatically, however I
can't find it documented in UPDATING or the release notes. I would have
thought that any change in default behaviour of the system should at least be
documented.
Ideally this change would have been implemented via a switch given that the
RFC mentioned in the code (RFC 5426) does not mandate truncation, but
recommends it when the network MTU is not known.
What's the best way to reach out to the maintainer to suggest a switch to
turn on this code?
Thanks,
Scott
Hi Scott,
Looks like this came in in base r332510 [1] via:
https://reviews.freebsd.org/D15011
The commit log message and review history may provide additional context
for the behaviour change (I haven't reviewed them)
I have CC'd the committer on this email, but in the meantime, and if you
wouldn't mind, it is worth reporting the issue via Bugzilla, so that we
track it, and so others can find it.

Actually, no. It just looks like this:
#!/bin/sh
# PROVIDE: waagent
# REQUIRE: sshd netif dhclient
# KEYWORD: nojail
. /etc/rc.subr
PATH=$PATH:/usr/local/bin:/usr/local/sbin
name="waagent"
rcvar="waagent_enable"
pidfile="/var/run/waagent.pid"
command="/usr/local/sbin/${name}"
command_interpreter="python"
command_args="start"
load_rc_config $name
run_rc_command "$1"
Which is why I have been jumping through some annoying hoops to try and
get this to work :-) Must admit I havent had the time to devote to it
properly yet, as I thought it would be relatively simple to do, but the
simple ways I tried didn't work.
-pete.

I thought this was too tricky, in any case it is rather fast to re-create it, so i guess the clobber stuff should work, In any case the modules where loaded, so the complain was just that, a warning. danny > > -- Ian > > ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
