t_cabsl source is in t_cabsl.cxx not t_cabsl.cc - the latter
is what bsd.tests.mk defaults to.
This only broke after my commit of share/mk/bsd.dep.mk rev 1.85
but I don't know why it didn't cause a problem previously.
When conversion specifier is not a derivative form of "%s", retrieve
input as 32bit integer, and then convert to string literal. Then we
can avoid interpretation from ASCII code to integer, which is
apparently byte-order depended.
integer one, which is not trapped for powerpc and aarch64.
Note that it is checked in lib/libc/gen/t_siginfo whether integer divide by
zero is interpreted as SIGFPE or not.
Now, all *_crash_fpe tests pass for powerpc, and nothing changes for amd64
at least.
This is much better handled by a user-land tool.

Note that the ioctl SIOCGIFINFO_IN6 no longer sets flags. That now
needs to be done using the pre-existing SIOCSIFINFO_FLAGS ioctl.
Compat is fully provided where it makes sense, but trying to turn on
RA handling will obviously throw an error as it no longer exists.
Note that if you use IPv6 temporary addresses, this now needs to be
turned on in dhcpcd.conf(5) rather than in sysctl.conf(5).
New tests:
- fork_setpgid
- vfork_setpgid
- posix_spawn_setpgid
- unrelated_tracer_fork_setpgid
- unrelated_tracer_vfork_setpgid
- unrelated_tracer_posix_spawn_setpgid
These tests trigger a kernel assert for pg_jobc going negative.
The tests are temporarily skipped.
The two files include-sub.mk and include-subsub.mk were never intended to
be test cases on their own. They belong to include-main.mk.

This logic correctly uses strncpy(3) to fully initialize a fixed-width field, and also ensures
NUL-termination on the next line as other users of the field expect.
Add -Werror=stringop-truncation to prevent build failure, when run with MKSANITIZER=yes.
Error was reported when build.sh was run with MKSANITIZER=yes flag.

Set SIGPASS for SIGCHLD for the traced child in the following tests:
- unrelated_tracer_fork*

There is a race that SIGCHLD might be blocked during forking and dropped.

fifo_vnodeop_opv_desc symbols.
Many filesystems ffs, lfs, ulfs, chfs, ext2fs etc. use fifofs
internally for their fifo vnops. NFS does too, but it also needs
networking anyway. Unfortunately fifofs brings in a lot of the
networking code so that the rumpkernel is not well partition. In
addition the fifo code is rarely used.
The existing hack depended on duplicating the above symbols and
adding minimal functionality for the majority of the the tests
(except the ffs and the puffs one). In these two cases both symbols
were loaded and the symbol sizes clashed which broke the sanitizers.
While this can be fixed with weak symbols and other kinds of
indirection, it is more straight forward to select between the
minimal and the full fifofs implementation by introducing a new
shared library librumpvfs_nofifofs.
SIGCHLD once blocked is discarded by the kernel as it has the
SA_IGNORE property. During the fork(2) operation all signals can be
shortly blocked and missed (unless there is a registered signal
handler in the traced child). This leads to a race in this test if
there would be an intention to catch SIGCHLD.

Instead of comparing old and new signal mask, just after the cloning
operation, check whether the expected signal is still masked and in
another test whether it is still ignored.
Catch up after t_ptrace_fork_wait.h r. 1.2.
ELF RTLD after rtld.c r. 1.204 introduced locking that wraps the fork
syscall. This locking changes signal mask of the calling process during
the forking process.
