Add tests of rtcache invalidation

branches: 1.5.6;
Move route check functions to net_common.sh

branches: 1.4.2;
Add tests of route flags using IPv6 addresses

Add tests for a gateway not on the local subnet

The tests are derived from the example at
http://www.netbsd.org/docs/network/#nonsubnetgateway ,
which has come up in PR 50717.

Add tests for route flags

branches: 1.1.2;
Time to start adding tests for the routing code to make that part
of the kernel more approachable.

Begin the task with an xfail test for PR kern/40455.

Get rid of all the -lrumpdev and -lrumpvfs that are no longer needed
after moving rump's mainbus from rumpdev to rumpkern.

Produces the same atf-run results as before.

tests: dump kernel stats on cleanup

branches: 1.12.4;
Adjust outputs of route's flags to include a numeric output

Fix typo

Add some tests to change flags of routes

branches: 1.9.2;
Accept DEBUG environment variable

By doing so, we can easily turn DEBUG on/off without modifying
the ATF scripts.

Add -lrumpdev so that tests work again.

Add some tests for route change

Remove extra grep

Make the test name self-descriptive

branches: 1.4.12;
Check for RUMP programs before using them.

branches: 1.3.4; 1.3.10;
Instead of doing 'atf_check ... sh -c foo', just do 'atf_check ... -x foo'.

Problem was fixed, don't expect to fail anymore

Clean up clunky eval strings

- Remove unnecessary \ at EOL
- This allows to omit ; too
- Remove unnecessary quotes for arguments of atf_set
- Don't expand $DEBUG in eval
- We expect it's expanded on execution

Check if ARP/NDP entries are purged when a related route is deleted

Restore ARP/NDP entries to route show and netstat -r

Requested by dyoung@ some time ago

Fix wrong comment

Check existence of ARP/NDP entries

Checking ARP/NDP entries is valid rather than checking routes.

branches: 1.15.6;
Add ifconfig -w to improve test stability

Share rump_server start/stop and interface creation/destruction functions

The common functions store socks of rump_servers, interfaces of rump_servers
and buses that intefaces connect and allow to destroy them with common
functions without specifying which socks, interfaces and buses we should
destroy.

This change reduces lots of similar setup/cleanup codes.

Move route check functions to net_common.sh

Accept DEBUG environment variable

By doing so, we can easily turn DEBUG on/off without modifying
the ATF scripts.

Add -lrumpdev so that tests work again.

Fix test names

Make a bunch of test names self-descriptive

Return 0 for $DEBUG=false case

Add more tests of RTF_REJECT

Add more tests of RTF_REJECT

Fix tests for blackhole routes

The gateway of a blackhole route must be a loopback interface.

Separate nexthop caches from the routing table

By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.

Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route

You can know details of behavior changes by seeing diffs under tests/.

Add tests of route flags using IPv6 addresses

tests: add tests for automatic route deletions on an address removal

Adjust outputs of route's flags to include a numeric output

Drop RTF_LLINFO flag (now it's RTF_LLDATA) from local routes

They don't have llinfo anymore. And also the change fixes unexpected
behavior of ARP proxy.

Tweak route get outputs to make tests work

"expire" value of route get output is unexpectedly a negative value
on rump kernel for some reasons and the tests almost always fail
on babylon5. So just ignore it to make tests work for now. Should
fix it in the future.
