validate that utimes() cannot update the times of a file on a read only
filesystem. The values are never actually used, but since
src/sys/kern/vfs_syscalls.c 1.535
they are validated for sanity, and the syscall returns EINVAL if the
values passed are invalid (tv_usec <0 or >= 1000000). If that happens
we don't get as far as the test which produces the EROFS that is expected
from this test (these tests - one for each filesystem type).
So, init the timeval structs (just to 0, the values will still not be
used) so that the EINVAL doesn't bite us before we're eaten by the EROFS
which is the way we're supposed to die.
If the syscall API args were labelled as "const" the compiler probably
would have caught the use of uninit'd vars and complained much sooner.
- Add cchar command to director test language to allow a complex character
to be defined and passed to the slave.
- Removed the distinction between args and returns internally to prevent
confusing the two which leads to errors and/or crashes.
- Converted mutt_test to use the new cchar definition and fixed the
check files for the test.
filesystem tests. Use the new -J option to pass the raw device into
the cleaner. This avoids the not rump safe getdiskrawname call and
makes sure we use an internal rump device name for cleaning. This
should fix bin/54488.
Define _REENTRANT for MKSANITIZER build. This is needed for at least stdio
code. This caused new build issued with duplicated symbols in few places
and rump kernel code picking different code paths borrowed from libc.
Handle all this in one go.
Add bsd.sanitizer.mk to share common code used by programs and libraries.
Switch from realall to beforeinstall target in .syms files. This is more
reliable in MKSANITIZER.
It didn't work correctly because rumphijack for vmstat didn't work expectedly;
vmstat has the sgid bit for kvm(3) and that prevents rumphijack from working.
Address the issue by cloning a vmstat binary without the sgid bit temporarily
and using it for rumphijack. Note that it's a workaround. vmstat should stop
using kvm(3) for /dev/kmem and drop the sgid bit eventually.
Allow to rename snprintf-like functions to avoid clashes with a sanitizer.
This tests needs a fixup to remove 'undef symbol' from the test code
generator.
A receiver of an ICMPv6 request packet creates a stale cache entry and it turns
into the delay state on replying the packet. After 5 second, the receiver sends
an NS packet as a reachability confirmation, which disturbs the test and causes
a unexpected result.
Should fix PR misc/54451
differences more exact, allowing between 0 and 1 s delay between the
expected wakeup and the actual event happening.
Also convert the QEMU special case code to the same scheme, but for now
disable it (with XXX mark) and see if the proper timing limits fix that
case too.
If not, we will re-enable the QEMU special case.
(it doesn't - that is, shouldn't) which includes processing -- as an
"end of options". The first arg is (always) the format string.
Remove/fix tests that assumed the contrary.
Problem (with printf) pointed out on tech-userlevel by Thierry Laronde.
