4c1a82cea5 pkgbase: Create a FreeBSD-utilities package and make it the default one
The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

705aad98c6 Some devices take undesired actions when RTS and DTR are
asserted. Some development boards for example will reset on DTR,
and some radio interfaces will transmit on RTS.

This patch allows "stty -f /dev/ttyu9.init -rtsdtr" to prevent
RTS and DTR from being asserted on open(), allowing these devices
to be used without problems.

484160a9cf sh: Add set -o pipefail
The pipefail option allows checking the exit status of all commands in a
pipeline more easily, at a limited cost of complexity in sh itself. It works
similarly to the option in bash, ksh93 and mksh.

Like ksh93 and unlike bash and mksh, the state of the option is saved when a
pipeline is started. Therefore, even in the case of commands like
  A | B &
a later change of the option does not change the exit status, the same way
  (A | B) &
works.

Since SIGPIPE is not handled specially, more work in the script is required
for a proper exit status for pipelines containing commands such as head that
may terminate successfully without reading all input. This can be something
like

(
        cmd1
        r=$?
        if [ "$r" -gt 128 ] && [ "$(kill -l "$r")" = PIPE ]; then
                exit 0
        else
                exit "$r"
        fi
) | head

aac5464b61 sh: Restore $((x)) error checking after fix for $((-9223372036854775808))
SVN r342880 was designed to fix $((-9223372036854775808)) and things like
$((0x8000000000000000)) but also broke error detection for values of
variables without dollar sign ($((x))).

For compatibility, overflow in plain literals continues to be ignored and
the value is clamped to the boundary (except 9223372036854775808 which is
changed to -9223372036854775808).

900c4ed3ca rm(1): Formalize non-functional status of -P flag
-P was introduced in 4.4BSD-Lite2 around 1994.  It overwrote file contents
with a pass of 0xff, 0x00, then 0xff, in a low effort attempt to "really
delete" files.

It has no user-visible effect; at the end of the day, the file is unlinked via
the filesystem.  Furthermore, the utility of overwriting files with patterned
data is extremely limited due to caveats at every layer of the stack[0] and
therefore mostly futile.  At the least, three passes is likely wasteful on
modern hardware[1].  It could also be seen as a violation of the "Unix
Philosophy" to do one thing per tiny, composable program.

Since 1994, FreeBSD has left it alone; OpenBSD replaced it with a single
pass of arc4random(3) output in 2012[2]; and NetBSD implemented partial, but
explicitly incomplete support for U.S. DoD 5220.22-M, "National Industrial
Security Program Operating Manual" in 2004[3].

NetBSD's enhanced comment above rm_overwrite makes a strong case for removing
the flag entirely:

> This is an expensive way to keep people from recovering files from your
> non-snapshotted FFS filesystems using fsdb(8).  Really.  No more.
>
> It is impossible to actually conform to the exact procedure given in
> [NISPOM] if one is overwriting a file, not an entire disk, because the
> procedure requires examination and comparison of the disk's defect lists.
> Any program that claims to securely erase *files* while conforming to the
> standard, then, is not correct.
>
> Furthermore, the presence of track caches, disk and controller write
> caches, and so forth make it extremely difficult to ensure that data have
> actually been written to the disk, particularly when one tries to repeatedly
> overwrite the same sectors in quick succession.  We call fsync(), but
> controllers with nonvolatile cache, as well as IDE disks that just plain lie
> about the stable storage of data, will defeat this.
>
> [NISPOM] requires physical media destruction, rather than any technique of
> the sort attempted here, for secret data.

As a first step towards evental removal, make it a placebo.  It's not like
it was serving any security function.  It is not defined in or mentioned by
POSIX.

If you are security conscious and need to erase your files, use a
woodchipper.  At a minimum, the entire disk needs to be overwritten, not
just one file.

d83db3fb6a Drop ed(1) "crypto"
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>

27181846bb pgrep naively appends the delimiter to all PIDs including the last
e.g. "pgrep -d, getty" outputs "1399,1386,1309,1308,1307,1306,1305,1302,"
Ensure the list is correctly delimited by suppressing the emission of the
delimiter after the final PID.

01df7d10a5 Remove SUBDIR ordering/uniquifying in *bin/Makefile
After the addition of SUBDIR.yes, uniquifying/ordering the SUBDIRs doesn't
make a whole lot of sense, and it's in effect a half measure.

Ordering SUBDIR (after adding SUBDIR.yes to it) in bsd.subdir.mk is a
separate change that warrants more discussion/testing, because while
the SUBDIR_PARALLEL work largely fixed dependency ordering for SUBDIRs,
there might be downstream FreeBSD consumers that rely on the SUBDIR
ordering.

63bd650f4b ln(1): fix -F behavior
When '-F' option is used, the target directory needs to be unlinked.
Currently, the modified target ("target/source") is being unlinked, and
since it doesn't yet exist, the original target isn't removed.
This is fixed by skipping the block where target is modified to
"target/source" when '-F' option is set.
Hence, a symbolic link (with the same name as of the original target) to
the source_file is produced.

Update the test for ln(1) to reflect fix for option '-F'
