SYSCTL_COUNTER_U64_ARRAY() macro.
- Add proper asserts to the SYSCTL_COUNTER_U64_ARRAY() macro that checks
the size of the first element of the array.
- Add an example to the counter(9) manual page how to use the
SYSCTL_COUNTER_U64_ARRAY() macro.
- Add some missing symbolic links for counter(9) while at it.
This is several year's worth of fail point upgrades done at EMC Isilon. They
are interdependent enough that it makes sense to put a single diff up for them.
Primarily, we added:
- Changing all mainline execution paths to be lockless, which lets us use fail
points in more sleep-sensitive areas, and allows more parallel execution
- A number of additional commands, including 'pause' that lets us do some
interesting deterministic repros of race conditions
- The ability to dump the stacks of all threads sleeping on a fail point
- A number of other API changes to allow marking up the fail point's context in
the code, and firing callbacks before and after execution
- A man page update

Specifically this fixes /usr/lib/libc.so stripping the paths to the
libraries. The reason for this in r266227 was both likely because ld(1) did
not fully respect --sysroot until r291226 and because of the lib32
build. The lib32 build does not use --sysroot into the /usr/lib32 path,
rather it only uses -L and -B into the /usr/lib32 path and --sysroot
into the normal (64bit) /usr/lib. The _LDSCRIPTROOT was added with
the ldscript support in bsd.lib.mk so that it builds a 32-bit-sysrooted pathed
ldscript in the object directory and then installs a normal unprefixed
version in installworld. This commit also fixes the rebuild during
install which was broken in r266227. This commit would break DIRDEPS_BUILD
build of lib32 but it does not currently have a way to build it anyhow.
For example, before this change we had in /usr/lib/libc.so:
GROUP ( libc.so.7 libc_nonshared.a libssp_nonshared.a )
Now it is restored to pre-r266227:
GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a /usr/lib/libssp_nonshared.a )
The motivation for this is in testing of lld.
From emaste:
lld does not have built-in search paths (e.g. /lib, /usr/lib) and relies on
-L arguments passed by the caller. As the linker is nearly always invoked
from the clang driver this is fine other than the fact that /usr/lib/libc.so
is an ldscript that refers to libc.so.7 which is in /lib, not /usr/lib.

No functional change.
This prevents adding empty targets to the main called target which is
confusing for debugging.

This also fixes META MODE rebuilding these because the 'number of build commands'
changed from the previous build.

Extend it to other cases of meta mode cookies so they get the proper rm

This obsoletes the _SKIP_BUILD check but keeps it for now until it
proves to be enough.
In the dirdeps build the first 'make all' or 'make' ran would invoke
'make dirdeps' which builds dependencies and then builds the current
directory in a sub-make (when BUILD_AT_LEVEL0 is no, which for us it
is). This behavior causes things attached to 'all:' to build in the
dirdeps phase AND the sub-make phase which creates all kinds of problems
for staging, meta file tracking, and races.

This also fixes meta tracking for the beforeinstall since it had been
marked .PHONY before (in bsd.sys.mk).

This is a follow-up to r291561 which reworked the bootstrap tool PATH
handling.
An example of this is when building lib/clang/libclangedit. At first
clang-tblgen will not be staged in the host tree so it will have
CLANG_TBLGEN=clang-tblgen set and exported. During the build though it
will stage clang-tblgen and then find it via the PATH. On the next
build it finds clang-tblgen in the stage directory and would set
CLANG_TBLGEN=<stagedir/usr/bin>/clang-tblgen thus causing the build
command to change. In both cases the same exact tool was used though so
there is no need to rebuild. If the tool did change the normal
meta/filemon handling would pick that up via timestamp comparisons and
rebuild.

An example of where this is needed is in share/examples which for
'etc-examples' runs 'make -C SRCTOP/etc etc-examples' which installs
to the default DESTDIR otherwise.

This came in r239572 for META_MODE handling but it doesn't make sense
since the staging is always done in make(all); make(buildincludes)
is never actually ran in the META_MODE build.

The meta file may decide the target is out of date but nothing
ensures that the *next* build will build this target if it
fails this time for some reason; it is still out-of-date
until it succeeds.

The inclusion of .MAKE.DEPENDFILE (.depend) has special logic in make
to ignore stale/missing dependencies. bmake 20160220 added a '.dinclude'
directive that uses the special logic for .depend when including the file.
This fixes a build error when a file is moved or deleted that exists in a
.depend.OBJ file. This happened in r292782 when sha512c.c "moved" and an
incremental build of lib/libmd would fail with:
make: don't know how to make /usr/src/lib/libcrypt/../libmd/sha512c.c. Stop
Now this will just be seen as a stale dependency and cause a rebuild:
make: /usr/obj/usr/src/lib/libmd/.depend.sha512c.o, 13: ignoring stale .depend for /usr/src/lib/libcrypt/../libmd/sha512c.c
--- sha512c.o ---
...
This rebuild will only be done once since the .depend.sha512c.o will
be updated on the build with the -MF flags.
This also removes -MP being passed for the .depend.OBJ generation (which
would create fake targets for system headers) since the logic is no
longer needed to protect from missing files.

One example is in cddl/usr.sbin/dtrace/tests/common/aggs. It could be
fixed but other uses of this would break, especially in the
DIRDEPS_BUILD which uses the group names for stage cookies.

This will allow Makefile.depend to properly capture all dependencies.
It is not 100% optimal but works. Other options would be to use *.meta
here which would include too much or to keep a Makefile.depend per PROG
and include it from the main Makefile.depend which would not be
straight forward.

Code may still be executing from the wrappers at unload time and thus is
not generally safe to unload. Converting the wrappers to use
EVENTHANDLER(9) will allow this to safely drain on active threads in
hooks. More work on EVENTHANDLER(9) is needed first.

There is no good way to guess if any of these will be needed but
they commonly are and add no extra overhead so just stage them.

Currently the base.txz distribution does not get the BSD.debug.dist mtree
extracted into it. So if you start from that and then try to build a 3rd-party
application outside of buildworld it will by-default try installing the
debug files into a missing directory if they are being installed into /usr/lib.
Check for the existence before forcing the directory to be created rather than
the older way of running a shell command with test -d || mkdir -p always.

This was a regression in r295985.
bsd.dep.mk adds to SRCS for dtrace probes, yacc grammars and some
others.
The code that is moving is planned to be removed once FAST_DEPEND is
default (and the only option) though since FAST_DEPEND doesn't use this.
