- Add a release-dvd.conf pkg(8) configuration file to override
the default FreeBSD.conf configuration.
- Remove architecture-specific pkg-stage.conf files, consolidate,
and move their contents to scripts/pkg-stage.sh.
- Use 'pkg -vv' to determine the ABI, which is used as the
cache directory.
Prior to these changes, it would be possible for pkg-stage to fetch
conflicting binary packages from multiple repositories.

The bug was introduced in r256956 "Improve ZFS N-way mirror read
performance".
The code in vdev_mirror_dva_select erroneously considers already
tried DVAs for the next attempt. Thus, it is possible that a failing DVA
would be retried forever.
As a secondary effect, if the attempts fail with checksum error, then
checksum error reports are accumulated until the original request
ultimately fails or succeeds. But because retrying is going on indefinitely
the cheksum reports accumulation will effectively be a memory leak.

If we prematurely free the name buffer and it gets quickly recycled,
then zfs_rename may see data from another lookup or even unmapped memory
via cn_nameptr.

Otherwise we could run into the following deadlock.
A thread has a transaction open and assigned to a transaction group.
That would prevent the transaction group from be quiesced and synced.
The thread is blocked in getnewvnode_reserve waiting for a vnode to
a be reclaimed. vnlru thread is blocked trying to enter ZFS VOP because
a filesystem is suspended by an ongoing rollback or receive operation.
In its turn the operation is waiting for the current transaction group
to be synced.
zfs_zget is always used outside of active transactions, but zfs_mknode
is always used in a transaction context. Thus, we hoist
getnewvnode_reserve from zfs_mknode to its callers.
While there, assert that ZFS always calls getnewvnode while having
a vnode reserved.

Problem case:
Original lookup returns route with GW set, so gw points to
rte->rt_gateway.
After that we're changing dst and performing lookup another time.
Since fwd host is most probably directly reachable, resulting
rte does not contain rt_gateway, so gw is not set. Finally, we
end with packet transmitted to proper interface but wrong
link-layer address.

sure to clear the lower 12 bits. We're adding the translation
attributes to the physical address and non-zero bits in the first
12 bits would give us something unexpected, including invalid bit
values. Those trigger nested general protection faults.
We do not have to clear the region bits, because they are ignored
anyway, so we can replace an existing dep instruction with the one
we need.
This fixes GP faults for the swapper thread, as it's the only thread
that has a direct-mapped stack. Since the bug is in the nested TLB
fault handler, the frequency of hitting the GP is in the order of
hours/days under load.
The SIGWINCH handler triggers breakage in libedit which is hard to fix; see
PR bin/169773.
Also, window size changes while a program is in foreground (and it rather
than sh will receive SIGWINCH) will now be picked up automatically.
Downside: it is now certain that a resize is only processed after pressing
<Enter>. If libedit is fixed, sh will most likely have to be changed also.

The resolver in libc creates a kqueue for watching a single file descriptor.
This can be done using poll() which should be lighter on the kernel and
reduce possible problems with rlimits (file descriptors, kqueues).

Redo r260506 by using the new TEST_METADATA functionality of bsd.test.mk
to mark the sh(1) and test(1) tests as not supporting root. This is to
get rid of hand-crafted Kyuafiles for these very simple cases.

Redo r260586 by using the new functionality in tap.test.mk to transparently
support perl-based test programs.
As a side-effect, we get rid of an explicit path to /usr/bin/perl by
replacing it with /usr/local/bin/perl (or as defined in tap.test.mk).
This also fixes the name of the legacy_test source file because this should
have always been legacy_test.pl and not legacy_test.sh. My mistake when
originally moving the code around without realizing that this was a perl
script.

Introduce a TAP_TESTS_PERL primitive to list test programs written in perl.
Only do this in tap.test.mk because I only expect perl-based test programs
with this interface.
This is very similar to TAP_TESTS_SH but the difference is that we record
in the Kyuafile that the test program requires a perl interpreter. This
in turn makes Kyua mark the test as skipped if the perl package is not yet
installed, instead of mysteriously failing to run the program.

Introduce a new, per-test-program TEST_METADATA.<program> variable that
contains a list of key/value paris describing metadata properties for
that test program. These properties are later written into the
auto-generated Kyuafile when using the KYUAFILE=auto functionality.
This is to avoid having to supply hand-crafted Kyuafiles when the needs
for metadata overrides are trivial.
While doing this, and because I am documenting TEST_METADATA, take the
chance to document the TEST_INTERFACE setting as well.

can be initiated in the context of a vcpu thread or from the bhyve(8) control
process.
The first use of this functionality is to update the vlapic trigger-mode
register when the IOAPIC pin configuration is changed.
Prior to this change we would update the TMR in the virtual-APIC page at
the time of interrupt delivery. But this doesn't work with Posted Interrupts
because there is no way to program the EOI_exit_bitmap[] in the VMCS of
the target at the time of interrupt delivery.

standard core target by declaring coreops_suppress_target with
initializer. This is also happening for non-cross kgdb, by
virtue of having fbsd-threads.c in libgdb and having it do the
exact same thing. Since fbsd-threads.c is not included in in
libgdb when building a cross debugger, we ended up with more
than 1 core file targets (the standard gdb core file target and
kgdb's libkvm based core file target) and this behaves the same
as not having a core target at all.
