When resetting the VFP state we need to discard any old state so we don't

Add a regression test for a scenario where a shadow vm object is shared

In situations when the current file name wasn't the first element on

This might cause us to pre-cache the same file twice.
Until now, the boot image can be embedded into the loader with
/sys/tools/embed_mfs.sh, and memory disk (MD) is already supported
in loader source. But due to memory disk (MD) driver isn't registered
to the loader yet, the boot image can't be boot from embedded memory

Capsicum did not prevent certain privileged networking operations,
specifically creation of raw sockets and network configuration ioctls.
However, these facilities can be used to circumvent some of the
restrictions that capability mode is supposed to enforce.
Add capability mode checks to disallow network configuration ioctls and
creation of sockets other than PF_LOCAL and SOCK_DGRAM/STREAM/SEQPACKET
internet sockets.

This fixes the failing test_read_append_filter_wrong_program test in CI
which has been failing since 01-Dec-2020.
Commit message from a1b7bf8013
Silence stderr in test_read_append_filter_program
When the FreeBSD testsuite runs the libarchive tests it checks that stderr
is empty. Since #1382 this is no longer the case. This change restores
the behaviour of silencing bunzip2 stderr but doesn't bring back the

With new ZFS prefetcher improvements it is no longer needed to fully

By default, makefs(8) has very few spare inodes in its output images,
which is fine for static filesystems, but not so great for VM images
where many more files will be added. Make makefs(8) use the same
default settings as newfs(8) when creating images with free space --
there isn't much point to leaving free space on the image if you
can't put files there. If no free space is requested, use current
behavior of a minimal number of available inodes.

Commit: f2f1ab39c0 ("pci_user: call bus_translate_resource before BAR mmap")
broke build for 32-bit platforms due to rman_res_t and vm_paddr_t
incompatible types. Fix that.
On some armv8 machines it is possible that the mapping between CPU
and PCI bus BAR base addresses is not 1:1. In case a BAR is allocated
in kernel using bus_alloc_resource_any this translation is handled in
ofw_pci_activate_resource.
Do the same in pci_user.c by calling bus_translate_resource devmethod.
This fixes mmaping BARs to userspace on Marvell SoCs (Armada 7k8k/CN913x)
and possibly many other platforms.

Add a man page for gptboot.efi. Describe when and how to use this as it differs
from the BIOS cases. Include cross reference for the preferred method described
in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to
the other.
This man page was heavily copied from the gptboot.8 man page by Warren Block.
They are different enough to need separate man pages for clarity, but there's
enough similarity that I worry about the duplication. In the really long term,
gptboot(8) will disappear, so having the same info here will help when that
day comes. In the short to medium term, the information is likely to not
change in gptboot(8) and any changes to gptboot.efi(8) will be easier to
make in a separate copy.
loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have
referenced gptboot.efi(8) from there.
