Get rid of static Atffiles and let bsd.test.mk generate them on the fly.

Add test case for PR kern/43548

Due to the nature of the feature under test, this one is a little
different, so let me explain how it works.

The test program forks and bootstraps a rump kernel in both processes.
It then configures shared memory interfaces in both. shmif is nice
in that it uses a mmaped file as the bus and does not require root
privileges for communication between two (or more) processes. The
child process then proceeds to increase icmp.returndatabytes as
indicated by the PR, while the parent process sets the global TTL
of the rump kernel to 1 (note: both values only affect the respective
rump kernels, not each other or more importantly the host kernel).
The parent then sends the bad packet which is supposed to be routed
by the child. If ip_icmp.c was too old, *boom* + fail; otherwise
nothing bad happens and the test exists with success after one
second.

Eventually this test can be extended into a framework for automated
testing of any networking code which requires (arbitrarily complex)
routing setups.

Centralize the base rump libraries into a variable used by all the other
Makefiles so that we can make changes to it centrally as needed and have
less mess. Fixes the sun2 build that needs rumpvfs after librump after
the latest changes.

Deal with fallout from the addition of
KERN_PROC_CWD in sysctl(3)
That is kern.proc.$$.KERN_PROC_CWD (I think - not that it matters here)

The effect is that -lrump now requires -lrumpvfs

This set of changes fixes (I believe) regular dynamic builds,
more might be required for static builds (will be verified soon).

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.

More need for librumpdev

Add tests for ICMP redirect timeout

Fix static linking for the tests: -lrump is also used by -lrumpuser,
so we also need -lrump after -lrumpuser. Fixes build for sun2.

branches: 1.3.12; 1.3.22;
Add another version of the simple ping test, this time written as a
shell script and using rump_server, rump.ifconfig and rump.ping.

XXX: uses rump_allserver for now, though, since i noticed a problem
where the rump kernel syscall vector does not get updated for
dlopen()'d libraries (and hence if you dlopen librumpnet.so, socket()
still gives ENOSYS). Me be fixink it later.

Don't play with "../.." in includes for h_macros.h; deal with it centrally.
Minor fixes.

Do not use artificial low timeouts - slow machines might be still paging
in all the rump environment. Bump timeout from 4 seconds to 20 (my shark
needs ~9).

Move more PR references from comments to ATF's "descr".

branches: 1.7.6;
Adjusts tests after import of atf-0.12:

- The use.fs property is gone.
- Mark the tests/fs/t_create:attrs test as broken when using the default
unprivileged-user:_atf setting. This probably deserves a fix somehow
but I'm not sure at this point.

add Makefile.inc everywhere so that we can set WARNS=4 by default. Amazing
how many bugs this found :-)

Remove stuff handled by common code now.

Calculate broadcast IP instead of requiring it as a config parameter.

make interface/routing configuration a bit more generic

Change the default value of DEBUG of stable tests to false

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 get_lladdr to net_common.sh

Accept DEBUG environment variable

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

Make test names self-descriptive

More adaptation to changed ifconfig output format.

Add tests for ICMP redirect timeout

In the "got %d/%d" message printed at the end of the pingsize test,
make the latter number show the actual number of ICMP packets the test
attempted to send. Thus, the two numbers can now be meaningfully
compared, and their difference indicates the number of packets lost.

branches: 1.23.2;
Handle errors better.
Fix test for checking we sent all the data we asked to.

Allow a valid sendto .... duh

Fix a printf(3)-like format in ATF ICMP t_ping.c

Use %zd for ssize_t, instead of %d.

Note value received. Harden another sendto for ENOBUFS.

Use raw buffer size (not aligned value) to limit packet size

make that u_int, because it is passed as a socket option.

add Makefile.inc everywhere so that we can set WARNS=4 by default. Amazing

setsockopt() wants int instead of size_t. Should fix this on LP64.

Add a delay between startup of pinger and pingee here too.

XXX: there's apparently some race condition which appears to trigger
if a broadcast arp arrives around the same time as the arpwhohas
is sent. This causes original packet to never be sent by the
arpwhohas requestor. If this rings a bell to someone, please let
me know.

.. put a timeout here just in case the receive does not increase
the counter.

Add a test for the "ping of death". Declare the test a success
when the receiver increases the "ip toolong" stat counter.

send pings in ascending order

Add a two-way floodping test and a test which sends icmp echos with
various sizes.

Substitute a surgical rump_server configuration for rump_allserver
now that it's possible. With warm fs cache, the startup time of
the former is 0.01s and the latter 0.1s. With cold caches it's
0.2s vs 2s.
