- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.
- Logical OR where binary OR was expected.
- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.
- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.
- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.
- Updated "EXAMPLES" section in SYSCTL manual page.

vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
a UDP packet. This implementation is based on RFC7348.
Currently, the IPv6 support is not fully compliant with the specification:
we should be able to receive UPDv6 packets with a zero checksum, but we
need to support RFC6935 first. Patches for this should come soon.
Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
network stack to support batching, GRO, and GSO. Each frame has to make
two trips through the network stack, and each frame will be at most MTU
sized. Performance suffers accordingly.
Some latest generation NICs have begun to support vxlan HW offloads that
we should also take advantage of. VIMAGE support should also be added soon.

Initial commit to include virtual machine images as part
of the FreeBSD release builds.
This adds a make(1) environment variable requirement,
WITH_VMIMAGES, which triggers the virtual machine image
targets when not defined to an empty value.
Relevant user-driven variables include:
o VMFORMATS: The virtual machine image formats to create.
Valid formats are provided by running 'mkimg --formats'
o VMSIZE: The size of the resulting virtual machine
image. Typical compression is roughly 140Mb, regardless
of the target size (10GB, 15GB, 20GB, 40GB sizes have been
tested with the same result).
o VMBASE: The prefix of the virtual machine disk images.
The VMBASE make(1) environment variable is suffixed with
each format in VMFORMATS for each individual disk image, as
well as '.img' for the source UFS filesystem passed to
mkimg(1).
This also includes a new script, mk-vmimage.sh, based on how
the VM images for 10.0-RELEASE, 9.3-RELEASE, and 10.1-RELEASE
were created (mk-vmimage.sh in ^/user/gjb/thermite/).
With the order in which the stages need to occur, as well as
sanity-checking error cases, it makes much more sense to
execute a shell script called from make(1), using env(1) to
set specific parameters for the target image than it does to
do this in make(1) directly.
r272236:
Use VMBASE in place of a hard-coded filename in the CLEANFILES
list.
r272262:
Remove a 'set -x' that snuck in during testing.
r272264:
release/Makefile:
Connect the virtual machine image build to the release
target if WITH_VMIMAGES is set to a non-empty value.
release/release.sh:
Add WITH_VMIMAGES to RELEASE_RMAKEFLAGS.
release/release.conf.sample:
Add commented entries for tuning the release build if the
WITH_VMIMAGES make(1) environment variable is set to
a non-empty value.

r272272:
Remove comments left in accidentally while testing, so the
VM /etc/fstab is actually created.
r272277:
Remove the UFS label from the root filesystem since it is added
by mkimg(1) as a gpt label, consistent with the fstab(5) entry.
r272279:
Comment cleanup in panic() message when mkimg(1) does not support
the requested disk image format.
r272376:
Separate release/scripts/mk-vmimage.sh to machine-specific
scripts, making it possible to mimic the functionality for
non-x86 targets.
Move echo output if MAKEFLAGS is empty outside of usage().
Remove TARGET/TARGET_ARCH evaluation.
r272380:
Avoid using env(1) to set values passed to mk-vmimage.sh,
and instead pass the values as arguments to the script,
making it easier to run this by hand, without 'make release'.
Add usage_vm_base() and usage_vm_image() usage helpers.
r272381:
After evaluating WITH_VMIMAGES is non-empty, ensure
the mk-vmimage.sh script exists before running it.
r272392:
Add WITH_COMPRESSED_VMIMAGES variable, which when set enables
xz(1) compression of the virtual machine images.
This is intentionally separate to allow more fine-grained
tuning over which images are compressed, especially in cases
where compressing 20GB sparse images can take hours.
r272412:
Document the new 'vm-image' target, and associated release.conf
variables.
r272413:
Remove two stray comments added during the initial iterations
of testing, no longer needed.

This will only take effect if PORTSDIR is not set, as previously supported.
Use .if exists(), for four specific possibilities relative to .CURDIR:
., .., ../.., and ../../.. The fourth possibility is primarily in case
ports ever grows a third level. If none of these paths exist, fall back to
the old default of /usr/ports.
This removes the need to set PORTSDIR explicitly (or via wrapper script) if
one is running out of a ports tree that is not in /usr/ports, but in a
home directory.
