* dracut: Fix race condition between load-key and importLorenz Hüdepohl2021-01-261-0/+8
| | | | | | | | | | zfs-load-key.sh is called by the dracut-pre-mount.service unit which has no explicit 'After' dependency on zfs-import.target. That way it can be that the pool has not yet been imported and the zfs-load-key.sh finishes without ever seeing the relevant pool.

* dracut: use /bin/sh instead of bash as the intepreterĐoàn Trần Công Danh2020-11-287-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Reviewed-by: Gabriel A.

* config/dracut/90zfs: handle cases where hostid(1) returns all zerosÉrico Rolim2020-11-141-1/+7
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d2bce6d03 added the 'make checkbashisms' target but did not resolve all of the bashisms in the scripts.

| | | | | | | | | | | | | | | | | | | | | | The horrible effects of human slavery continue to impact society. The casual use of the term "slave" in computer software is an unnecessary reference to a painful human experience. This commit removes all possible references to the term "slave". Implementation notes: The zpool.d/slaves script is renamed to dm-deps, which uses the same terminology as `dmsetup deps`. References to the `/sys/class/block/$dev/slaves` directory remain. This directory name is determined by the Linux kernel. Although `dmsetup deps` provides the same information, it unfortunately requires elevated privileges, whereas the `/sys/...` directory is world-readable.

* bash scripts: use /usr/bin/env for bash shebangsGraham Christensen2020-02-103-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Encryption Stability and On-Disk Format FixesTom Caputi2018-02-021-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Properly use the Dracut cleanup hook to order pool shutdownRudd-O2016-10-174-2/+13
| | | | | | | | | | | | | | | | | | 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. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Manuel Amador (Rudd-O) <[email protected]> Closes #5287

* Use a different technique to detect whether to mount-zfsRudd-O2016-10-062-19/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".
