Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
- correct RTA_NETMASK processing
- correct -A filter behavior (do not advert aggregated route to other if)
- better signal handling
- mandate getifaddrs
- do not advert connected routes on !IFF_UP routes. experimental
sync with kame
- keep the case consistent between the actual name and what's referenced.
e.g, if it's `foo', don't use '.Nm Foo' at the start of a sentence.
- remove unnecessary `.Nm foo' after the first occurrence (except for
using `.Nm ""' if there's stuff following, or for the 2nd and so on
occurrences in a SYNOPSIS
- use Sx, Ic, Li, Em, Sq, and Xr as appropriate
- remove obsolete non-advanced-api support.
- if a routing entry exists for aggregate prefix (-A), do not overwrite
the routing entry (exit with error).
rip6query: RIPng query (similar to ripquery)
NOTE: we usually do not run route6d on end nodes at startup (rtsol should do
the trick). So I figured that route6d can be in /usr/sbin, not in /sbin
(routed is in /sbin). Correct me if I'm wrong.
