I looked at creating a test scenario for the following piece of code
from src/sys/kern/kern_fork.c:
881 if ((nprocs >= maxproc - 10 && priv_check_cred(td->td_ucred,
882 PRIV_MAXPROC, 0) != 0) || nprocs >= maxproc) {
883 error = EAGAIN;
884 goto fail;
885 }
I came up with a test scenario for this:
http://people.freebsd.org/~pho/kern_fork_test.c
But it is not 100% repeatable, as I would expect many other kernel
tests will be.
The test case runs as expected, until for example root decides to do a
parallel buildworld.
Is this a show stopper?
