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.
- 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.
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.
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.
