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>

0629b15276 setfacl: add recursive functionality
Add a -R option to setfacl to operate recursively on directories, along
with the accompanying flags -H, -L, and -P (whose behaviour mimics
chmod).

A patch was submitted with PR 155163, but this is a new implementation
based on comments raised in the Phabricator review for that patch
(review D9096).

30417f2cd4 Change ps(1) output width to unlimited if not interactive
Apply patch submitted with PR 217159 to make ps use unlimited
width when not associated with a terminal (i.e., none of stdout, stdin,
or stderr is a tty). Update comments and man page correspondingly.
This change was requested to work around lack of -ww in scripts from
third-party packages, including Hadoop, and adds a small measure of
Linux compatibility. Hopefully few if any non-interactive scripts
depend on the old default of 79.

0fdf7fa846 Convert ls(1) to not use libxo(3)
libxo imposes a large burden on system utilities. In the case of ls, that
burden is difficult to justify -- any language that can interact with json
output can use readdir(3) and stat(2).

Logically, this reverts r291607, r285857, r285803, r285734, r285425,
r284494, r284489, r284252, and r284198.

Kyua tests continue to pass (libxo integration was entirely untested).

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.
