Integrate

in to the FreeBSD test suite as
tests/sys/geom/class/{concat,eli,gate,mirror,nop,raid3,shsec,stripe,uzip}
The tools/regression/geom and tools/regression/geom_part testcases are being
left alone because both test sets are both currently broken.
The majority of this work was done on ^/user/ngie/more-tests2 . The differences
are as follows:
- tests/sys/geom/class/Makefile.inc is not present; it was
inlined into the class's Makefiles for explicitness.
- The testcases officially require root via kyua
- The geom_gate(4) tests don't use the pidfile changes proposed in

* Remove a duplicate error check in mk_pair_of_sockets
* Always close sockets in the success path of ATF test cases. Don't
bother with the error paths, because those are mostly assertions
anyway. Most of these socket leaks were reported by Coverity.
All of them are harmless, because each ATF test case runs in its

Export current system call code and argument count for system call entry
and exit events. To preserve the ABI, the new fields are moved to the
end of struct thread in these branches (unlike HEAD) and explicitly copied
when new threads are created. In addition, the new tests are only added
in 10.
r287386:
Export current system call code and argument count for system call entry
and exit events. procfs stop events for system call tracing report these
values (argument count for system call entry and code for system call exit),
but ptrace() does not provide this information. (Note that while the system
call code can be determined in an ABI-specific manner during system call
entry, it is not generally available during system call exit.)
The values are exported via new fields at the end of struct ptrace_lwpinfo
available via PT_LWPINFO.
r288949:
Fix various edge cases related to system call tracing.
- Always set td_dbg_sc_* when P_TRACED is set on system call entry
even if the debugger is not tracing system call entries. This
ensures the fields are valid when reporting other stops that
occur at system call boundaries such as for PT_FOLLOW_FORKS or
when only tracing system call exits.
- Set TDB_SCX when reporting the stop for a new child process in
fork_return(). This causes the event to be reported as a system
call exit.
- Report a system call exit event in fork_return() for new threads in
a traced process.
- Copy td_dbg_sc_* to new threads instead of zeroing. This ensures
that td_dbg_sc_code in particular will report the system call that
created the new thread or process when it reports a system call
exit event in fork_return().
- Add new ptrace tests to verify that new child processes and threads
report system call exit events with a valid pl_syscall_code via
PT_LWPINFO.
r288993:
Document the recently added pl_syscall_* fields in struct ptrace_lwpinfo.
Add more mmap tests related to character devices.
- Add cdev-related tests for bad args.
- Add two simple tests cases for mapping /dev/zero that test for

Add various tests to ensure that invalid arguments passed to mmap()
trigger failures.
Note: most of the tests that should provoke an EINVAL error do not
pass on stable/10 as stable/10 does not have the changes that added
more strict parameter checking to mmap(). Those changes will not be
merged to stable/10, so I have disabled them via #if 0 with a comment
explaining why.
Various fixes to orphan handling which also fix issues with following
forks.
283281:
Always set p_oppid when attaching to an existing process via procfs
tracing. This matches the behavior of ptrace(PT_ATTACH). Also,
the procfs detach request assumes p_oppid is always set.
283282:
Only reparent a traced process to its old parent if the tracing process is
not the old parent. Otherwise, proc_reap() will leave the zombie in place
resulting in the process' status being returned twice to its parent.
Add test cases for PT_TRACE_ME and PT_ATTACH which are fixed by
this change.
283562:
Do not allow a process to reap an orphan (a child currently being
traced by another process such as a debugger). The parent process does
need to check for matching orphan pids to avoid returning ECHILD if an
orphan has exited, but it should not return the exited status for the
child until after the debugger has detached from the orphan process
either explicitly or implicitly via wait().
Add two tests for for this case: one where the debugger is the direct
child (thus the parent has a non-empty children list) and one where
the debugger is not a direct child (so the only "child" of the parent
is the orphan).
283647:
Tweak the description of when waitpid() doesn't return any status for a
non-blocking wait to avoid the word "empty".
283836:
Consistently only use one end of the pipe in the parent and debugger
processes and do not rely on EOF due to a close() in the debugger.
284000:
Add a CHILD_REQUIRE macro similar to ATF_REQUIRE for use in child processes
of the main test process.
286158:
Clear P_TRACED before reparenting a detached process back to its
original parent. Otherwise the debugee will be set as an orphan of
the debugger.
Add tests for tracing forks via PT_FOLLOW_FORK.

MFC r265092
Fix a panic when removing an IP address from an interface, if the same

264887, which changed the fibnum parameter in the call to rtalloc1_fib() in
ifa_switch_loopback_route() from RT_DEFAULT_FIB to RT_ALL_FIBS. The
solution is to use the interface fib in that call. For the majority of

Correct ARP update handling when the routes for network interfaces are

Restricting an interface's routes to the FIB to which it is assigned (by
setting net.add_addr_allfibs=0) causes ARP updates to fail with "arpresolve:

Replace 4.4BSD Lite's unix domain socket backpressure hack with a cleaner
mechanism, based on the new SB_STOP sockbuf flag. The old hack dynamically
changed the sending sockbuf's high water mark whenever adding or removing
data from the receiving sockbuf. It worked for stream sockets, but it never
worked for SOCK_SEQPACKET sockets because of their atomic nature. If the
sockbuf was partially full, it might return EMSGSIZE instead of blocking.
The new solution is based on DragonFlyBSD's fix from commit
3a6117bbe0ed6a87605c1e43e12a1438d8844380 on 2008-05-27. It adds an SB_STOP
flag to sockbufs. Whenever uipc_send surpasses the socket's size limit, it
sets SB_STOP on the sending sockbuf. sbspace() will then return 0 for that
sockbuf, causing sosend_generic and friends to block. uipc_rcvd will
likewise clear SB_STOP. There are two fringe benefits: uipc_{send,rcvd} no
longer need to call chgsbsize() on every send and receive because they don't
change the sockbuf's high water mark. Also, uipc_sense no longer needs to
acquire the UIPC linkage lock, because it's simpler to compute the
st_blksizes.
There is one drawback: since sbspace() will only ever return 0 or the
maximum, sosend_generic will allow the sockbuf to exceed its nominal maximum
size by at most one packet of size less than the max. I don't think that's
a serious problem. In fact, I'm not even positive that FreeBSD guarantees a
socket will always stay within its nominal size limit.

db_show_unpcb.
tests/sys/kern/unix_seqpacket_test.c
Clear expected failures from ATF.
Fix PR kern/185813 "SOCK_SEQPACKET AF_UNIX sockets with asymmetrical buffers
drop packets". It was caused by a check for the space available in a
sockbuf, but it was checking the wrong sockbuf.
sys/sys/sockbuf.h
sys/kern/uipc_sockbuf.c
Add sbappendaddr_nospacecheck_locked(), which is just like
sbappendaddr_locked but doesn't validate the receiving socket's space.
Factor out common code into sbappendaddr_locked_internal(). We
shouldn't simply make sbappendaddr_locked check the space and then call
sbappendaddr_nospacecheck_locked, because that would cause the O(n)
function m_length to be called twice.
sys/kern/uipc_usrreq.c
Use sbappendaddr_nospacecheck_locked for SOCK_SEQPACKET sockets,
because the receiving sockbuf's size limit is irrelevant.
tests/sys/kern/unix_seqpacket_test.c
Now that 185813 is fixed, pipe_128k_8k fails intermittently due to
185812. Make it fail every time by adding a usleep after starting the
writer thread and before starting the reader thread in test_pipe. That
gives the writer time to fill up its send buffer. Also, clear the
expected failure message due to 185813. It actually said "185812", but
that was a typo.

Only use -lpthread for unix_seqpacket_test, not for all test programs.

kern/unix_seqpacket_test.c
Fix compiler warnings. Most were benign, but rcvbuf_oversized
wasn't working as intended because I forgot to set the buffer sizes.
test_eagain_*_* should've been using nonblocking sockets instead of blocking
sockets. The error was not exposed as long as the kernel suffered from PR
kern/185812. Now corrected, these tests pass on DragonFlyBSD 3.6.0.
r261081
Replace the old unix_seqpacket and unix_seqpacket_exercise
tests, which were a little broken and not automatable, with
unix_seqpacket_test. It's coverage is a superset of the old
tests and it uses ATF. It includes test cases for bugs
kern/185813 and kern/185812.
r261133
Fix the Makefiles so that the tests I submitted in r261081 will
actually get built.
r261615
tests/sys/Makefile
use TESTS_SUBDIRS for kern instead of SUBDIRS. I don't
think it makes a difference in this case, but
TESTS_SUBDIRS is generally correct for subdirectories
that contain tests.
This is a MFC of the following into stable/10:
- r257097 Set up the /usr/tests hierarchy.
- r257098 Add missing WITHOUTTESTS file.
- r257100 Add a tests(7) manual page.
- r257105 Disable WITHTESTS= for now.
- r257848 Fix buildworld when WITHTESTS is enabled.
- r257850 Subsume the functionality of MKATF into MKTESTS.
- r257851 Handle the removal of the test suite when WITHOUTTESTS=yes.
- r257852 Install category Kyuafiles from their category directories.
- r258232 Install BSD.tests.mtree when MKTESTS is yes.
Note that building with WITH_TESTS is still broken at this point (and
hence why WITHOUT_TESTS is the set as the default). Subsequent pullups
will fix the remaining issues.
