The removal (and creation of a port) has been pre-announced in UPDATING
1 month ago. Packages are available for all supported FreeBSD vesions.
I did not think that another entry in UPDATING is required to note the
actual removal.
No MFC is planned - CTM shall be kept in base for all releases up to 12.x.

GNU binutils ld.bfd 2.17.50 does not support ifuncs and produces broken
binaries when ifuncs are in use. When LLD_IS_LD is default we have an
ifunc-capable system linker and can just avoid installing ld.bfd.

Add non-default descriptions for the benefit of WIP branches.
llvm-profdata is used with llvm-cov for code coverage (although llvm-cov
can also operate independently in a gcov-compatible mode).
Although llvm-profdata can be used independently of llvm-cov it makes
sense to group these under one option.

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.

Inheriting $PATH during the build phase can cause the build to fail when
compiling on a different system due to missing build tools or incompatible
versions somewhere in $PATH. This has cause build failures for us before
due to the jenkins slaves still running FreeBSD 10.
Listing the tools we depend on explicitly instead of just using whatever
happens to be in $PATH allows us to check that we don't accidentally add a
new build dependency.
All tools that do no need to be bootstrapped will now be symlinked to
${WORLDTMP}/legacy/bin and during the build phase $PATH will only contain
${WORLDTMP}. There is also a new variable "BOOTSTRAP_ALL_TOOLS" which can
be set to force compiling almost all bootstrap tools instead of symlinking
them. This will not bootstrap tools such as cp,mv, etc. since they may be
used during the build and for those we should really only be using POSIX
compatible options.
Furthermore, this change is required in order to be able to build on
non-FreeBSD hosts. While the same binaries may exist on Linux/MacOS they
often accept different flags or produce incompatible output.

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.

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.
This is currently disabled until __dso_handle support is added.

vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
the active BE can't be renamed. It doesn't make sense in our context to
*not* use -u, so use it.
Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.
A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

Checking for any include below ${SRCTOP}/sys is too strict and breaks
e.g. mkimg which includes sys/sys/disk. ABI issues will only be caused
by including headers in sys/sys since they might not match the host.

This has two advantages:
1) We no longer create lots of empty directories that are not needed
2) This is a requirement for building on non-FreeBSD hosts since mtree will
only exist after the bootstrap-tools phase there.

This can cause surprising errors if the build tools is built against
headers that don't match the host system. It is also required in order
to allow building on non-FreeBSD systems where the headers in
/usr/include/sys are usually completely incompatible with those in the
source tree.
I added an error to Makefile.boot if this is done and found this was
only the case in libnv. With this error in the Makefile ABI breakages
such as r336019 should no longer be possible.

BPF (eBPF) is an independent instruction set architecture which is
introduced in Linux a few years ago. Originally, eBPF execute
environment was only inside Linux kernel. However, recent years there
are some user space implementation (https://github.com/iovisor/ubpf,
https://doc.dpdk.org/guides/prog_guide/bpf_lib.html) and kernel space
implementation for FreeBSD is going on
(https://github.com/YutaroHayakawa/generic-ebpf).
The BPF target support can be enabled using WITH_LLVM_TARGET_BPF, as it
is not built by default.
