Despite that dracut has a hard dependency on bash,
its modules doesn't, dracut only has a hard dependency on bash for
module-setup (on a fully usable machine). Inside initramfs, dracut
allows users choose from a list of handful other shells, e.g. bash,
busybox, dash, mkfsh.
In fact, my local machine's initramfs is being built with dash,
and it's functional for a very long time.
Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also
allows our users to have that right, too.
Let's fix the problem 'make checkbashisms' reported and allows our users
to have that right, again.
For 'plymouth' case, let's simply run the command inside the if instead
of checking for the existence of command before running it, because the
status is also failture if plymouth is unavailable.
While we're at it, let's remove an unnecessary fork for grep in
zfs-generator.sh.in and its following complicated 'if elif fi' with
a simple 'case ... esac'.
To support this change, also exclude 90zfs from "make checkbashisms"
because the current CI infrastructure ships an old version of
"checkbashisms", which complains about "command -v", while the current
latest "checkbashisms" thinks it's fine. In the near future, we can
revert that change to "Makefile.am" when CI infrastructure is updated.

On systems with musl libc, hostid(1) always prints "00000000", which
will cause improper behavior when the 90zfs module is configured in a
dracut initramfs. Work around this by copying the host /etc/hostid if
the file exists, and otherwise only write /etc/hostid if hostid(1)
returns something meaningful. This avoids zgenhostid creating a random
/etc/hostid for the initramfs, which could lead to errors when trying to
import the pool if spl_hostid isn't defined in the kernel command line.
Furthermore, tag the /etc/hostid file as hostonly, since it is system
specific and shouldn't be taken into account when trying to use an
initramfs generated in one system to boot into a different system.

Not all systems / distros have a `/bin/bash`, and these scripts are
more difficult to run at development time.
For example, my system is NixOS which doesn't have a /bin/bash. This
is not a problem for NixOS building ZFS as a package: the build
environment automatically replaces these shebangs with corrected
paths.
The problem is much more annoying at development time: either the
scripts don't run, or I correct them for my local machine and deal with
a perpetually dirty work tree.
Before committing this patch I confirmed there are existing scripts
which use `/usr/bin/env` to locate bash, so I am thinking this is a
safe transformation.
There are a handful of other shebangs in this repository which don't
work on my system. This patch is useful on its own specifically for
`commitcheck.sh`, otherwise I can't validate my commits before
submission.
Here are the remaining shebangs which NixOS systems won't have:
1274 #!/bin/ksh -p
91 #!/bin/ksh
89 #! /bin/ksh -p
2 #!/bin/sed -f
1 #!/usr/bin/perl -w
1 #!/usr/bin/ksh
1 #!/bin/nawk -f
plus this which will create an invalid shebang in
`tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`:
echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh
I chose to leave those alone for now, and gauge the interest in this
much smaller patch first.
The fixes for these are easy enough by simply using `/usr/bin/env ksh`:
91 #!/bin/ksh
1 #!/usr/bin/ksh
The fix for the other set is much trickier. Quoting the GNU coreutils
manual:
Most operating systems (e.g. GNU/Linux, BSDs) treat all text after
the first space as a single argument. When using env in a script it
is thus not possible to specify multiple arguments.
and not all `env`'s support arguments.
Mine (GNU Coreutils 8.31) does, though this feature is new since
April 2018, GNU Coreutils 8.30:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2
and worse, requires the -S argument:
-S, --split-string=S process and split S into separate arguments;
used to pass multiple arguments on shebang
lines
Example:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr"
/nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory
/nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr"
2
1
GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's
would be unhappy with the `-S`:
https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation
BusyBox v1.30.1 does not, and does not have a `-S`-like option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr"
env: can't execute 'sort -nr': No such file or directory
Toybox 0.8.1 also does not, and also does not have a `-S` option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr"
env: exec sort -nr: No such file or directory
---
At any rate, if this patch merges and the remaining ~1,500 are updated,
the much larger patch should probably include a checkstyle-like test
asserting all new shebangs use `/usr/bin/env`. I also don't mind
dealing with NixOS weirdness if the project would prefer that.

Because + is a reserved character in ZFS, it's used as a

root=ZFS=root+pool/filesystem+name will properly expand by

The on-disk format for encrypted datasets protects not only
the encrypted and authenticated blocks themselves, but also
the order and interpretation of these blocks. In order to
make this work while maintaining the ability to do raw
sends, the indirect bps maintain a secure checksum of all
the MACs in the block below it along with a few other
fields that determine how the data is interpreted.
Unfortunately, the current on-disk format erroneously
includes some fields which are not portable and thus cannot
support raw sends. It is not possible to easily work around
this issue due to a separate and much smaller bug which
causes indirect blocks for encrypted dnodes to not be
compressed, which conflicts with the previous bug. In
addition, the current code generates incompatible on-disk
formats on big endian and little endian systems due to an
issue with how block pointers are authenticated. Finally,
raw send streams do not currently include dn_maxblkid when
sending both the metadnode and normal dnodes which are
needed in order to ensure that we are correctly maintaining
the portable objset MAC.
This patch zero's out the offending fields when computing
the bp MAC and ensures that these MACs are always
calculated in little endian order (regardless of the host
system's byte order). This patch also registers an errata
for the old on-disk format, which we detect by adding a
"version" field to newly created DSL Crypto Keys. We allow
datasets without a version (version 0) to only be mounted
for read so that they can easily be migrated. We also now
include dn_maxblkid in raw send streams to ensure the MAC
can be maintained correctly.
This patch also contains minor bug fixes and cleanups.

Closes#6962
* PBKDF2 implementation changed to OpenSSL implementation.
* HKDF implementation moved to its own file and tests
added to ensure correctness.
* Removed libzfs's now unnecessary dependency on libzpool
and libicp.
* Ztest can now create and test encrypted datasets. This is
currently disabled until issue #6526 is resolved, but
otherwise functions as advertised.
* Several small bug fixes discovered after enabling ztest
to run on encrypted datasets.
* Fixed coverity defects added by the encryption patch.
* Updated man pages for encrypted send / receive behavior.
* Fixed a bug where encrypted datasets could receive
DRR_WRITE_EMBEDDED records.
* Minor code cleanups / consolidation.

On Void Linux (x86_64 musl) libgcc_s.so is located in "/usr/lib"
so it is not found by dracut and it produces an error.
Add a simple additional path check for "/usr/lib/libgcc_s.so*"
and install it in the initramfs.

while these are source by dracut (which is a bash script)
the practical difference is small, but it is more correct:
/bin/sh is not bash on all systems (e.g. Debian and its
derivatives use /bin/dash as /bin/sh by default).

The vdev_id script requires awk, grep, and head. Use dracut_install to
ensure that these commands are available in the initrd environment.

When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.
Important note: this code will not accomplish its stated goal until this
bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432
That bug impacts more than just ZFS. It impacts LUKS, dmraid, and
unmount during poweroff. It is a Fedora-wide bug.

The behavior of the Dracut module was very wrong before.
The correct behavior: initramfs should not run `zfs-mount` to completion
if the two generator files exist. If, however, one of them is missing,
it indicates one of three cases:
* The kernel command line did not specify a root ZFS file system, and
another Dracut module is already handling root mount (via systemd).
`mount-zfs` can run, but it will do nothing.
* There is no systemd to run `sysroot.mount` to begin with.
`mount-zfs` must run.
* The root parameter is zfs:AUTO, which cannot be run in sysroot.mount.
`mount-zfs` must run.
In any of these three cases, it is safe to run `zfs-mount` to completion.
`zfs-mount` must also delete itself if it determines it should not run,
or else Dracut will do the insane thing of running it over and over again.
Literally, the definition of insanity, doing the same thing that did not
work before, expecting different results. Doing that may have had a great
result before, when we had a race between devices appearing and pools
being mounted, and `mount-zfs` was tasked with the full responsibility
of importing the needed pool, but nowadays it is wrong behavior and
should be suppressed.
I deduced that self-deletion was the correct thing to do by looking at
other Dracut code, because (as we all are very fully aware of) Dracut
is entirely, ahem, "implementation-defined".
