For developers gensnmptree can now generate functions for enums to convert
between enums and strings and to check the validity of a value.
The sources in FreeBSD are now in sync with the upstream which allows to
bring in IPv6 modifications.
Add vertical space between struct definition and function prototype.
Use "NULL" to describe zero pointers, instead of "zero."
Remove perhaps unclear "can not" and replace. Tag struct member names used
with appropriate tags.
Currently libclang_rt is not provided for cross-building and as such
is not connected to cross-tools. For building clang once in universe
it is likely that libclang_rt won't exist for the universe toolchain
but even if it did it would not support anything but the native arch.
So explicitly check for support before enabling h_raw.

Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.
This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.
Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
geli_groups="storage backup"
geli_storage_flags="-k /etc/geli/storage.keys"
geli_storage_devices="ada0 ada1"
geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"

Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally. Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.
The relocation of libraries allows libraries to be build for 32-bit
compat. This also reduces the number of non-standard builds in
the system.
This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit
system out of the box as it will look in the wrong place for libraries
unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

This effectively reverts r335449 and changes the previous MK_LLD_IS_LD
to a MK_LLD_BOOTSTRAP check. If !TOOLS_PREFIX then these sources are
always built for llvm-objdump, lld, and llvm-cov. When TOOLS_PREFIX
is set then they are only needed if lld is being bootstrapped.

This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld. The current list is:
* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86
To not influence anything right now, all of these are on by default, in
situations where clang is enabled.
Selectively turning a few targets off manually should work. Turning on
only one target should work too, even if that target does not correspond
to the build architecture. (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)
I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled. The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time. For a full
buildworld the difference will probably be less pronounced, though.

MK_LLD is for the installed lld while MK_LLD_BOOTSTRAP is for the build
tool. For WITH_SYSTEM_LINKER it is necesarry to separate the logic of
these two. When building libllvm TOOLS_PREFIX will be defined and
MK_LLD_BOOTSTRAP should be checked instead.

Pull out the note about overlapping buffers to its own paragraph, as it
applies to all routines documented by this page.
Emphasize the potentially surprising strncpy(3) behavior of zero-filling the
remainder of a buffer larger than the source string.
Encourage strlcpy use; remove portability note about strlcpy(3). Adapting a
strlcpy-using code base to a platform that does not provide strlcpy in libc
is so trivial as to not be worth mentioning. (Just copy strlcpy.c out of
any BSD libc, or include and link the pre-packaged libbsd library on non-BSD
platforms.)
Likewise, expand the page's warning about ease of potential misuse to cover
all functions documented herein, and explicitly suggest using strlcpy most
of the time. The text was mostly cribbed from a similar suggestion in
gets(3).
Finally, document the remaining valid use of strncpy -- the rare
fixed-length record with no expectation of nul-termination.

This patch adds a new socket option, SO_REUSEPORT_LB, which allow multiple
programs or threads to bind to the same port and incoming connections will be
load balanced using a hash function.
Most of the code was copied from a similar patch for DragonflyBSD.
However, in DragonflyBSD, load balancing is a global on/off setting and can not
be set per socket. This patch allows for simultaneous use of both the current
SO_REUSEPORT and the new SO_REUSEPORT_LB options on the same system.
Required changes to structures:
Globally change so_options from 16 to 32 bit value to allow for more options.
Add hashtable in pcbinfo to hold all SO_REUSEPORT_LB sockets.
Limitations:
As DragonflyBSD, a load balance group is limited to 256 pcbs (256 programs or
threads sharing the same socket).
This is a substantially different contribution as compared to its original
incarnation at svn r332894 and reverted at svn r332967. Thanks to rwatson@
for the substantive feedback that is included in this commit.
