picobsd/tinyware has had this compact HTTPD server for a long time, and some
people do use it. Move it out into usr.sbin well in advance of any action
being taken on picobsd.
This has been gated behind an HTTPD option defaulted to *off*, primarily for
two reasons:
1.) This code likely needs a good audit, as it's been living off in picobsd
land for a long time, and
2.) We don't currently ship an httpd and this may not be a welcome surprise.

The current approach of injecting manifest into mac_veriexec is to
verify the integrity of it in userspace (veriexec (8)) and pass its
entries into kernel using a char device (/dev/veriexec).
This requires verifying root partition integrity in loader,
for example by using memory disk and checking its hash.
Otherwise if rootfs is compromised an attacker could inject their own data.
This patch introduces an option to parse manifest in kernel based on envs.
The loader sets manifest path and digest.
EVENTHANDLER is used to launch the module right after the rootfs is mounted.
It has to be done this way, since one might want to verify integrity of the init file.
This means that manifest is required to be present on the root partition.
Note that the envs have to be set right before boot to make sure that no one can spoof them.

This initial integration takes googlemock/googletest release 1.8.1, integrates
the library, tests, and sample unit tests into the build.
googlemock/googletest's inclusion is optionally available via `MK_GOOGLETEST`.
`MK_GOOGLETEST` is dependent on `MK_TESTS` and is enabled by default when
built with a C++11 capable toolchain.
Google tests can be specified via the `GTESTS` variable, which, in comparison
with the other test drivers, is more simplified/streamlined, as Googletest only
supports C++ tests; not raw C or shell tests (C tests can be written in C++
using the standard embedding methods).
No dependent libraries are assumed for the tests. One must specify `gmock`,
`gmock_main`, `gtest`, or `gtest_main`, via `LIBADD` for the program.
More information about googlemock and googletest can be found on the
Googletest [project page](https://github.com/google/googletest), and the
[GoogleMock](https://github.com/google/googletest/blob/v1.8.x/googlemock/docs/Documentation.md)
and
[GoogleTest](https://github.com/google/googletest/tree/v1.8.x/googletest/docs)
docs.
These tests are originally integrated into the build as plain driver tests, but
will be natively integrated into Kyua in a later version.

UEFI related headers were copied from edk2.
A new build option "MK_LOADER_EFI_SECUREBOOT" was added to allow
loading of trusted anchors from UEFI.
Certificate revocation support is also introduced.
The forbidden certificates are loaded from dbx variable.
Verification fails in two cases:
There is a direct match between cert in dbx and the one in the chain.
The CA used to sign the chain is found in dbx.
One can also insert a hash of TBS section of a certificate into dbx.
In this case verifications fails only if a direct match with a
certificate in chain is found.

These libraries don't compile on non-C++-11 capable compilers, e.g., g++ 4.2.1
and its corresponding implementation of the c++ library, i.e., libstdc++.
Blacklist compilation on all non-C++-11 capable compilers and give others the
option of opting out of building/installing gmock/gtest via MK_GOOGLETEST.
This option is controlled by MK_CXX and MK_TESTS, as ATF compilation is.
Building binaries as PIE allows the executable itself to be loaded at a
random address when ASLR is enabled (not just its shared libraries).
With this change PIE objects have a .pieo extension and INTERNALLIB
libraries libXXX_pie.a.
MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, as
they explicitly reference .a libraries in their Makefiles. These can
be addressed on an individual basis later. MK_PIE is also disabled for
rtld-elf because it is already position-independent using bespoke
Makefile rules.
Currently only dynamically linked binaries will be built as PIE.

Some WITH_/WITHOUT_ defaults will likey change in the future (e.g. as we
migrate to copyfree base system components).
Add non-default descriptions for the benefit of WIP branches.
The linker's -z now flag sets the DF_BIND_NOW flag, which signals to the
runtime loader that all relocation processing should be performed at
process startup rather than on demand. In combination with lld's
default of enabling relro this causes the GOT to be made read-only when
the process starts, preventing straightforward GOT overwrite attacks.
Shawn Webb discovered a failure on HardenedBSD with BIND_NOW and ifunc
use, which resulted in my rtld fix in r340137. Add a BIND_NOW knob as
it is trivial to do so and is a useful ELF hardening feature. This
change is equivalent to HardenedBSD's but not identical as there are
other diffs/conflicts nearby.
Note that our ELF Tool Chain readelf does not currently decode the
DF_BIND_NOW flag - see PR232983.

You should not be using DES. You should not have been using DES for the
past 30 years.
The ed DES-CBC scheme lacked several desirable properties of a sealed
document system, even ignoring DES itself. In particular, it did not
provide the "integrity" cryptographic property (detection of tampering), and
it treated ASCII passwords as 64-bit keys (instead of using a KDF like
scrypt or PBKDF2).
Some general approaches ed(1) users might consider to replace the removed
DES mode:
1. Full disk encryption with something like AES-XTS. This is easy to
conceptualize, design, and implement, and it provides confidentiality for
data at rest. Like CBC, it lacks tampering protection. Examples include
GELI, LUKS, FileVault2.
2. Encrypted overlay ("stackable") filesystems (EncFS, PEFS?, CryptoFS,
others).
3. Native encryption at the filesystem layer. Ext4/F2FS, ZFS, APFS, and
NTFS all have some flavor of this.
4. Storing your files unencrypted. It's not like DES was doing you much
good.
If you have DES-CBC scrambled files produced by ed(1) prior to this change,
you may decrypt them with:
openssl des-cbc -d -iv 0 -K <key in hex> -in <inputfile> -out <plaintext>

In the last decade(s) we have seen both short term or long term projects
committed to the tree which were considered or even marked "experimental".
While out-of-tree development has become easier than it used to be in
CVS times, there still is a need to have the code shipping with HEAD but
not enabled by default.
While people may think about VIMAGE as one of the recent larger, long term
projects, early protocol implementations (before they are standardised)
are others. (Free)BSD historically was one of the operating systems
which would have running code at early stages and help develop and
influence standardisation and the industry.
Give developers an opportunity to be more pro-active for early adoption
or running large scale code changes stumbling over each others but not
the user's feet. I have not added the option to NOTES in order to avoid
breaking supported option builds, which require constant compile testing.

all the function pointers to be called in the correct order from the

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.

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools. If either check fails though then
libclang is built.
The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".
-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.
A new 'make test-system-linker' target is added to see the logic results.
Makefile.inc1:
CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
logic as done with SYSTEM_COMPILER. This also required moving where
bsd.linker.mk was read since XLD needs to be set before parsing it. This
creates a situation where src.opts.mk can not test LINKER_FEATURES or
add LLD_BOOTSTAP to BROKEN_OPTIONS.

It was an old TRE that had plenty of bugs and no performance gain over
regex(3). I disabled it by default in r323615, and there was some confusion
about what the knob does- likely due to poor naming on my part- to the tune
of "well, it sounds like it should speed things up" (mentioned by multiple
people).
To compound this, I have no intention of maintaining a second regex
implementation. If someone would like to step up and volunteer to maintain a
lean-and-mean implementation for grep, this is OK, but we have very few
volunteers to maintain even our primary regex implementation.

The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.
The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.
A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.
