and sent in by Greg Hudson as seen in PR misc/3227. Basically what it
does is adds a flushall option which deletes all but localhost routes.
This is done by andoring in a flag called doall (1 means do all routes
including gateway, 0 means do a regular flush). I have seen some
platforms that do this. I tested it out on ipv4 only, it works as
advertised. Commit was approved by christos@.
muck up the routing tables. The patch was submitted by Quentin Garnier
<netbsd@quatriemek.com> and tweaked a little after it was reviewed
by Christos Zoulas <christos@netbsd.org>. Final change/commit approved
by Christos.
address corresponding to RTA_GATEWAY, or nothing if it doesn't exist.
Modify the exit value of route depending on this, so that one can do
stuff like:
#!/bin/sh
gw=`route -sn get default 2>/dev/null`
if [ -z "$gw" ]; then
echo no default route
exit 1
fi
ping -w1 -c1 $gw >/dev/null 2>&1
if ! route -sn get $gw >/dev/null; then
echo default gateway not responding
exit 1
fi
echo default gateway is at $gw
and check netmask (or prefix) length as well as the destination
address when determining if a route is a "default" or not. This means
that the output from 'route show' will no longer say:
Internet6:
Destination Gateway Flags
default localhost UG
default localhost UG
but instead
Internet6:
Destination Gateway Flags
::/104 localhost UGR
::/96 localhost UGR
which makes much more sense.
let static routes overwrite cloned routes, as cloned routes can come back again
if necessary. behavior same as freebsd/bsdi, code partially from bsdi42.
(NRL rt->rt_parent was not added)
should fix PR 11916 and maybe some other PRs with ARP behavior.
recompilation of usr.sbin/route6d is suggested.
XXX route show is total duplicate of netstat -r, we need to either remove
route show, or share the same source code, otherwise maintenance cost
bites (and is biting) us
* reset af to 0 in flushroutes() and newroute()
* cleanup -DSMALL:
- `flush' and AF_APPLETALK is supported (the latter had partial support)
- AF_NS, AF_ISO, and AF_CCITT are not supported at all (rather than being
- partially unsupported).
