same as the previous commit to ifconfig - handle a mediatype of IBSS
without failing/complaining.
Internally inside wpa_s things treat IBSS/ADHOC as equivalent.
Right now net80211 is configured as type IBSS but then treats it
as mediatype ADHOC. This doesn't change that; it just correctly handles
being given a mediatype of IBSS.
wpa_supplicant actually calls the wpa ioctl with cipher 0 as part
of the teardown process and this returns an ioctl error.
It's required as part of the (hopefully!) upcoming encrypted
IBSS support which does indeed do the above as part of interface
setup and then exits ungracefully when it gets an ioctl error.
(I'll fix wpa_supplicant in a later commit as part of other work.)
The dependency for ypldap is only with WITH_NIS, but libevent is small
enough to not warrant the extra logic and maintenance cost here so just
always build it.

Really this should not be a DPSRCS. The acct_test.c should not #include
convert.c, but just link it in as a normal SRCS.

This is so that 'make depend' is not a required build step in these
files.
DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anything
which can safely be in SRCS should be. DPSRCS is mostly just a way to
generate files that should not be linked into the final PROG/LIB. For
headers and grammars it is safe for them to be in SRCS since they will
be excluded during linking and installation.
The only remaining uses of DPSRCS are for generating .c or .o files that
must be built before 'make depend' can run 'mkdep' on the SRCS c files
list. A semi-proper example is in tests/sys/kern/acct/Makefile where a
checked-in .c file has an #include on a generated .c file. The
generated .c file should not be linked into the final PROG though since
it is #include'd. The more proper way here is just to build/link it in
though without DPSRCS. Another example is in sys/modules/linux/Makefile
where a shell script runs to parse a DPSRCS .o file that should not be
linked into the module. Beyond those, the need for DPSRCS is largely
unneeded, redundant, and forces 'make depend' to be ran. Generally,
these Makefiles should avoid the need for DPSRCS and define proper
dependencies for their files as well.
An example of an improper usage and why this matters is in usr.bin/netstat.
nl_defs.h was only in DPSRCS and so was not generated during 'make all',
but only during 'make depend'. The files including it lacked proper
depenencies on it, which forced running 'make depend' to workaround that
bug. The 'make depend' target should mostly be used for incremental build
help, not to produce a working build. This specific example was broken in
the meta build until r287905 since it does not run 'make depend'.
The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:
SRCS:M*.h' when there is no .depend file.

This is going to be used to allow DIRDEPS to be bootstrapped off of
LIBADD/DPADD. It currently works for internal libraries which have a
DIR defined for them but also use the .a library from a src-mapped obj
directory. It can also be useful for using -L without a --sysroot per
LIBADD to use the OBJDIR version of the libraries.
I didn't review every LIBADD, so it is possible this is missing some.

This avoids using the staged headers for sys/crypto/sha2/*.h, such as sha256.h,
which added an unneeded pre-build dependency on libmd to libcrypt. This
header is an INCS in lib/libmd, but found via .PATH in sys/crypto/sha2.
Since the libcrypt build was already using the in-src libmd headers
directly, just teach it how to find the sha256.h header as well.

We need to not use -nostdinc since it breaks building of clang itself. Use
-isystem rather than -I/usr/include and -nostdinc which gets us using
the stage include directory before searching the real host headers.
This allows removing more of the -I hacks to get host headers since the
headers are no longer excluded. The -B seemed unneeded.
This fixes building of secure/lib/libcrypto which was looking at the
/usr/include/openssl/asn1.h header rather than the staged one.
This fixes building of clang which wants to find its own internal
headers in the STAGEDIR/usr/lib/clang/* path.

The main problem was bitrot after elftoolchain being swapped in for the
GNU toolchain.
This also reworks how the list of 'host allowed' libraries is determined
to only allow INTERNALLIBs, which is needed for libelftc to come in.
For usr.bin/readelf use the same hack, as libelf and libdward, to bring in
the needed sys/ headers for host builds. This has not yet been a problem due
to readelf not being built as a host tool in buildworld. This is possible
in the meta build though when building the toolchain.

Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file. There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

This is just as Makefile.inc1 does it for these phases. Otherwise some
of the build tools are not found and used properly, such as 'make-roken'
in the kerberos5 build on older releases.

librtld_db only needs libutil.h to build, not the libproc library. So
it can safely use its header and allow libproc to depend on librtld_rb
to be built first to link. This is required after fixing ld --sysroot
in r291226.

Because of how osreldate.h was being built with newvers.sh, which always
spat out a vers.c dependent on SVN or git, the meta mode build was
considering osreldate.h to depend on the current git or SVN index. This
would lead to entire tree rebuilds when modifying git's index. There's
no reason to be generating vers.c here so just skip it.
While here, in mk-osreldate.sh rename PARAM_H to proper PARAMFILE (which
newvers.sh already has a default for) and remove unneeded export.

For this case, the normal META MODE staging logic should be used. The
BSARGS having DESTDIR= is due to Makefile.inc1 overriding DESTDIR to
something when appropriate. For the toolchain stage META MODE is in charge of
it, not Makefile.inc1.
At least include/, if staging it to the host stagedir, was impacted from
this. Staging of include.host is not yet done.

I added MYBEACON support a while ago to listen to beacons that are only
for your configured BSSID. For AR9380 and later NICs this results in
a lot less chip wakeups in station mode as it then only shows you beacons
that are destined to you.
However in IBSS mode you really do want to hear all beacons so you can do
IBSS merges. Oops.
So only use MYBEACON for STA + not-scanning, and just use BEACON for
the other modes it used to use BEACON for.
This doesn't completely fix IBSS merges though - there are still some
conditions to chase down and fix.
I've seen some cases where we get stuck in a loop constantly trying to
negotiate A-MPDU TX which is definitely not supposed to happen.
This will let me see if it's something funky with the retry count or
not.
only for read locks on pcbs. The same race can happen with write
lock semantics as well.
The race scenario:
- Two threads (1 and 2) locate pcb with writer semantics (INPLOOKUP_WLOCKPCB)
and do in_pcbref() on it.
- 1 and 2 both drop the inp hash lock.
- Another thread (3) grabs the inp hash lock. Then it runs in_pcbfree(),
which wlocks the pcb. They must happen faster than 1 or 2 come INP_WLOCK()!
- 1 and 2 congest in INP_WLOCK().
- 3 does in_pcbremlists(), drops hash lock, and runs in_pcbrele_wlocked(),
which doesn't free the pcb due to two references on it.
Then it unlocks the pcb.
- 1 (or 2) gets wlock on the pcb, runs in_pcbrele_wlocked(), which doesn't
report inp as freed, due to 2 (or 1) still helding extra reference on it.
The thread tries to do smth with a disconnected pcb and crashes.

The indent_wrapper tool only accepts full context diffs and works by
identifying the surrounding C-block touched by a diff and passing only
that to indent for styling. In the end a diff is produced or an
external tool like meld can be invoked, to show the styling
differences.
