0f18e6f6d6 bwn(4): Conditionalize "RX decryption attempted" message on a new
BWN_DEBUG_HWCRYPTO debug flag.

The MAC will attempt decryption (and set BWN_RX_MAC_DEC) even if a key has
not been supplied to the hardware; this is expected behavior, and there's
no need to spam users' console with this debugging printf.

6026dcd7ca Add support for zstd-compressed user and kernel core dumps.
This works similarly to the existing gzip compression support, but
zstd is typically faster and gives better compression ratios.

Support for this functionality must be configured by adding ZSTDIO to
one's kernel configuration file. dumpon(8)'s new -Z option is used to
configure zstd compression for kernel dumps. savecore(8) now recognizes
and saves zstd-compressed kernel dumps with a .zst extension.

08a3b42fdb Narrow a race, and fix a leak, in g_part_wither
A race in g_part_wither() can lead to I/O being performed with a freed GEOM
when the device disappears.  Close the race as best as we can for now,
following the code patterns from g_part_ctl_destroy() and g_part_ctl_undo().
This also fixes a leak, as g_wither_geom() does not wither providers, it
only orphans them, so the partition entries would never get destroyed in
g_wither_washer().

Note, this is not a complete fix, it can still race with g_part_start(), the
race has merely been narrowed.

67dcd64ab8 linuxkpi: Do not leak pages on put.
When the owner of the wire reference releases the last reference, it
might be that the page was already attempted to be freed (but free
cannot be performed at that time due to wire).  Check that the page
was removed from the object as the indicator of the free attempt and
finish the free operation if so.

c4be9169c0 Do not leak rv->psind in some specific situations.
Suppose that we have an object with a mapped superpage, and that all
pages in the superpages are held (by some driver).  Additionally,
suppose that the object is terminated, e.g. because the only process
mapping it is exiting.  Then the reservation is broken, but the pages
cannot be freed until later, when they are unheld.  In this situation,
the reservation code cannot clean psind, since no pages are freed, and
the page is freed and then reused with invalid psind.

Clean psind on vm_reserv_break() to avoid the situation.

This fixes UNH IPv6 conformance test cases v6LC_4_1_08 and v6LC_4_1_09,

7c7c726bca siba(4): Ignore disabled per-core address match entries.
Previously, the address regions described by disabled admatch entries would
be treated as being mapped to the given core; while incorrect, this was
essentially harmless given that the entries describe unused address space
on the few affected devices.

We now perform parsing of per-core admatch registers and interrupt flags in
siba_erom, correctly skip any disabled admatch entries, and use the
siba_erom API in siba_add_children() to perform enumeration of attached
cores.

7cafeaa1fd Add Lua as a scripting langauge to /boot/loader
liblua glues the lua run time into the boot loader. It implements all
the runtime routines that lua expects. In addition, it has a few
standard 'C' headers that nueter various aspects of the LUA build that
are too specific to lua to be in libsa. Many refinements from the
original code to improve implementation and the number of included lua
libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default
module path. Numerous cleanups from the original GSoC project,
including hacking libsa to allow lua to be built with only one change
outside luaconf.h.

Add the final bit of lua glue to bring in liblua and plug into the
multiple interpreter framework, previously committed.

Add LOADER_LUA option, currently off by default.

Presently, this is an experimental option. One must opt-in to using
this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been
lightly tested, so keep a backup copy of your old loader handy.
The menu code, coming in the next commit, hasn't been exhaustively
tested. A LUA boot loader is 60k larger than a FORTH one, which is
80k larger than a no-interpreter one. Subtle changes in size
may tip things past some subtle limit (the binary is ~430k now
when built with LUA). A future version may offer coexistance.

Bump FreeBSD version to 1200058 to mark the milestone.
