Fix wrong WIFCONTINUED() status.

Add FORKEE_ASSERTX()/FORKEE_ASSERT() for forkee; simplify code

A child process cannot call atf functions and expect them to magically
work like in the parent.
The printf(3) messaging from a child will not work out of the box as well
without estabilishing a communication protocol with its parent. To not
overcomplicate the tests - do not log from a child and use err(3)/errx(3)
wrapped with FORKEE_ASSERT()/FORKEE_ASSERTX() as that is guaranteed to work.

Simplify and cleanup code of the tests.

Mark ptraceme4 as expected failure, assume that Linux&FreeBSD are correct

Raising SIGCONT from a ptrace(2)d child should be catched with waidpid(2)
as WIFCONTINUED() false and WIFSTOPPED() true; not both true as it does not
make much sense.

Hmmm, if we omit if_43.c from the SRCS list, then we break the i386
build for one of the XEN kernels.

Adding it back to the list.  At least the build will be successful.

XXX This is probably not the end of this saga, as we still have the
XXX redefined-symbol issue when loading the compat module on amd64.
XXX But for now, a working build for the vast majority of users
XXX (including our automated test suites) is more important than a
XXX successfully-loadable compat module.

Add new test traceme4 in t_ptrace

This test verifies calling raise(2) with the SIGCONT argument in the child.
The parent is notified with it and asserts that WIFCONTINUED() and
WIFSTOPPED() are both set.

XXX: This behavior is surprising. Linux for the same code-path returns false
for WIFCONTINUED() and true for WIFSTOPPED().

Include <stdlib.h> for EXIT_FAILURE.

This code covers (uncovers issues?) WIFCONTINUED() and is the last planned
test in the ptraceme category.

Add new test traceme3 in t_ptrace

This test is modeled after traceme1 and traceme2 with the goal to test if
the child was terminated with a received signal passed with PT_CONTINUE.

Currently the three traceme tests verifies three possible status values from
waitpid(2) called by the parent:
- WIFEXITED(status),
- WIFSIGNALED(status),
- WIFSTOPPED(status)
with associated macros:
- WEXITSTATUS(status),
- WTERMSIG(status),
- WCOREDUMP(status),
- WSTOPSIG(status).

In traceme3 has been assumed that Ctrl-C (SIGINT) does not emit core(5).

Really comment out if_43.c this time.  (I need sleep and/or caffeine.)

(pgoyette)

Use proper characgter to introduce comments!

(pgoyette)

if_43.o gets included from libcompat automatically, due to two calls
to compat_cvtcmd() in if.c.  Ideally, if.c would be modified to have
a pointer to a no-op compat_cvtcmd() and that pointer would get
replaced by compat_modcmd(MODULE_CMD_INIT, ...) code.  But for now,
just don't include it in the compat module at all.

(pgoyette)

Reorganize SRCS lists for libcompat, compat.kmod, sysv_ipc.kmod.

- Share lists between the libcompat and module makefiles.
- Include some omitted entries in compat.kmod:
  . if_43.c
  . kern_sa_60.c
  . kern_time_30.c
  . rndpseudo_50.c
  . rtsock_14.c
  . rtsock_50.c
  . rtsock_70.c
  . uipc_syscalls_40.c
  . uipc_syscalls_50.c
- Exclude a (harmless) spurious entry in sysv_ipc.kmod on LP64 systems:
  . kern_ipc_10.c

* Split sys/kern/sys_process.c into three parts:

        2 - common ptrace(2) syscall code (shared with compat_netbsd32)
        3 - support routines that are shared with PROCFS and/or KTRACE

* Add module glue for #1 and #2.  Both modules will be built-in to the
  kernel if "options PTRACE" is included in the config file (this is
  the default, defined in sys/conf/std).

* Mark the ptrace(2) syscall as modular in syscalls.master (generated
  files will be committed shortly).

* Conditionalize all remaining portions of PTRACE code on a new kernel
  option PTRACE_HOOKS.

XXX Instead of PROCFS depending on 'options PTRACE', we should probably
    just add a procfs attribute to the sys/kern/sys_process.c file's
    entry in files.kern, and add PROCFS to the "#if defineds" for
    process_domem().  It's really confusing to have two different ways

Fix file name auto completion in one specific case.

For example if you do
$mkdir -p /tmp/dir1/dir2

Then:
$ls /tmp/di <TAB> auto completes to
$ls /tmp/dir1/

Hitting <TAB> again auto completes to
$ls /tmp/dir1/dir2

Whereas it should auto complete to
$ls /tmp/dir1/dir2/

Essentially, in cases like above where you have to hit <TAB> twice to get
to the match and there is only one match (because only one file/sub-directory) then
auto complete doesn't work correctly. It doesn't append a trailing slash (in case
of directory) or a space (in case of a file) to the match name.

this change.

Error recovery stops normal queue processing but didn't resume it
when the recovery succeeded. Add the missing calls to scsipi_channel_thaw
similar to kern/41867.

CAM status values are used as xs_status and must be mapped to XS values.
Add the missing mapping for CAM_CMD_TIMEOUT.

POSIX harder the pthread_mutex_timedlock(3) prototype

Add missing __restrict keyword to the first pointer parameter.

It was already used for the second argument, should not be a functional
change and generated code should be the same.

This new form is now aligned with POSIX.

Add new test t_timedmutex

This test is a clone on t_mutex with additional two tests for timed-mutex
specific block.

All simple-mutex (not with the timed property according to the C11 wording)
specific tests are covered by pthread_mutex_timedlock(3) with parameter
ts_lengthy of sufficiently large tv_sec value (right now UINT16_MAX). If,
a test will hang, it won't wait UINT16_MAX seconds, but will be terminated
within the default timeout for ATF tests (right now 300 [sec] in my
NetBSD/amd64 setup).

This test was inspired by a classic selflock test failure of
pthread_mutex_timedlock(3) of the following form:

#include <assert.h>
#include <errno.h>
#include <pthread.h>
#include <stdio.h>
#include <time.h>

int main(int argc, char **argv)
{
pthread_mutex_t mtx;
        struct timespec ts;

        ts.tv_sec = 0;
        ts.tv_nsec = 1000;
        printf("ts{.tv_sec = %d, .tv_nsec=%ld}\n", ts.tv_sec, ts.tv_nsec);
        fflush(stdout);

        printf("mtx_init\n");
assert(pthread_mutex_init(&mtx, NULL) == 0);

        printf("mtx_lock\n");
assert(pthread_mutex_lock(&mtx) == 0);

        printf("mtx_timedlock\n");
assert(pthread_mutex_timedlock(&mtx, &ts) == ETIMEDOUT);

        printf("mtx_unlock\n");
assert(pthread_mutex_unlock(&mtx) == 0);

printf("mtx_destroy\n");
        assert(pthread_mutex_destroy(&mtx) == 0);

return 0;
}

Current NetBSD implementation wrongly hangs on this test.

The issue was detected during development of the C11 portable threads.

My local tests in chroot presents that the are further issues:

t_timedmutex (21/25): 10 test cases
    mutex1: [0.001142s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:75: *param != 20
    mutex2: [0.261499s] Passed.
    mutex3: [0.261496s] Passed.
    mutex4: [0.001204s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:265: pthread_mutex_timedlock(&mutex, &ts_lengthy): Connection timed out
    mutex5: [0.001235s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:337: pthread_mutex_timedlock(&mutex5, &ts_lengthy): Connection timed out
    mutex6: [21.218497s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:512: start != 1
    mutexattr1: [0.001328s] Passed.
    mutexattr2: [0.001175s] Passed.
    timedmutex1: [301.119397s] Failed: Test case timed out after 300 seconds
    timedmutex2: [301.123081s] Failed: Test case timed out after 300 seconds
[623.990659s]

I'm also receiveing the same failure in the mutex6 test in t_mutex, so
there might be a false positives due to local chroot(8) issues.

reorganize ffs_truncate()/ffs_indirtrunc() to be able to partially
succeed; change wapbl_register_deallocation() to return EAGAIN
rather than panic when code hits the limit

callers changed to either loop calling ffs_truncate() using new
utility ufs_truncate_retry() if their semantics requires it, or
just ignore the failure; remove ufs_wapbl_truncate()

this fixes possible user-triggerable panic during truncate, and
resolves WAPBL performance issue with truncates of large files

Fix wm(4) input drop packet counter.

WMREG_RNBC is incremented when there is no available buffers in host
memory. However, ethernet controller can receive packets in such case
if there is space in phy's FIFO. That is, ethernet controller drops
packet only if there is no available buffers *and* there is no space
in phy's FIFO.
So, the number of dropped packets should be added WMREG_MPC only.
