During runtime, you need the following additional
dependencies:
Features:
+* ability to insert trusted configuration and secrets into the boot parameters
+ of a kernel booting in a VM or on baremetal some way, via TPM
+ protection. idea:
+ 1. pass via /proc/bootconfig
+ 2. for secrets: put secrets in node of /proc/bootconfig, decrypt them via
+ TPM early on in PID 1, put them in $CREDENTIAL_PATH logic
+ 3. for config: put signed data in node /proc/booconfig, validate via TPM
+ early on in PID 1, put data into /run/bootconfig/ as individual files
+ 4. boot loader/stub should pick these up automatically from the boot loader
+ file systems
+
+* journald: support RFC3164 fully for the incoming syslog transport, see
+ https://github.com/systemd/systemd/issues/19251#issuecomment-816601955
+
+* nspawn: support uid mapping bind mounts, as defined available in kernel 5.12,
+ for all our disk image needs
+
+* homed: if kernel 5.12 uid mapping mounts exist, use that instead of recursive
+ chowns.
+
+* cryptsetup: tweak tpm2-device=auto logic, abort quickly if firmware tells us
+ there isn't any TPM2 device anyway. that way, we'll wait for the TPM2 device
+ to show up only if registered in LUKS header + the firmware suggests there is
+ a device worth waiting for.
+
+* systemd-sysext: optionally, run it in initrd already, before transitioning
+ into host, to open up possibility for services shipped like that.
+
+* add a new switch --auto-definitions=yes/no or so to systemd-repart. If
+ specified, synthesize a definition automatically if we can: enlarge last
+ partition on disk, but only if it is marked for growing and not read-only.
+
+* add a switch to homectl (maybe called --first-boot) where it will check if
+ any non-system users exist, and if not prompts interactively for basic user
+ info, mimicking systemd-firstboot. Then, place this in a service that runs
+ after systemd-homed, but before gdm and friends, as a simple, barebones
+ fallback logic to get a regular user created on uninitialized systems.
+
* maybe add a tool that displays most recent journal logs as QR code to scan
off screen and run it automatically on boot failures, emergency logs and
such. Use DRM APIs directly, see
* systemd-repart: read LUKS encryption key from $CREDENTIALS_PATH
* introduce /dev/disk/root/* symlinks that allow referencing partitions on the
- disk the rootfs is on in a reasonably secure way.
+ disk the rootfs is on in a reasonably secure way. (or maybe: add
+ /dev/gpt-auto-{home,srv,boot,…} similar in style to /dev/gpt-auto-root as we
+ already have it.
* systemd-repart: add a switch to factory reset the partition table without
immediately applying the new configuration again. i.e. --factory-reset=leave
or so. (this is useful to factory reset an image, then putting it into
another machine, ensuring that luks key is generated on new machine, not old)
+* systemd-repart: support setting up dm-integrity with HMAC
+
+* systemd-repart: maybe remove half-initialized image on failure. It fails
+ if the output file exists, so a repeated invocation will usually fail if
+ something goes wrong on the way.
+
+* systemd-repart: drop pager mode on normal operation?
+
* move logind udev rules to top-level rule.d/ directory
* move multiseat vid/pid matches from logind udev rule to hwdb
With all that in place if nspawn host and container payload are up-to-date
enough we have a very simple way to make host users available in containers.
-* systemd-sysusers: pick up passwords from credentials logic, so that users can
- easily set root user pw. enable cred inheriting for root user from PID 1, so
- that for containers we can configure the root pw automatically via nspawn's
- --set-credential= switch. (Also do this for systemd-firstboot)
-
* whenever we receive fds via SCM_RIGHTS make sure none got dropped due to the
reception limit the kernel silently enforces.
* systemd-analyze netif that explains predictable interface (or networkctl)
-* port selinux code from mallinfo() to mallinfo2() once added to glibc
-
* Add service setting to run a service within the specified VRF. i.e. do the
equivalent of "ip vrf exec".
-* export action of device object on sd-device, so that monitor becomes useful
-
-* add root=tmpfs that mounts a tmpfs to /sysroot (to be used in combination
- with usr=…, for a similar effect as systemd.volatile=yes but without the
- "hide-out" effect). Also, add root=gpt-auto-late support or so, that is like
- root=gpt-auto but initially mounts a tmpfs to /sysroot, and then revisits
- later after systemd-repart ran. Usecase: let's ship images with only /usr
- partition, then on first boot create the root partition. In this case we want
- to read the repart data from /usr before the root partition exists. Add
- usr=gpt-auto that automatically finds a /usr partition.
-
* change SwitchRoot() implementation in PID 1 to use pivot_root(".", "."), as
documented in the pivot_root(2) man page, so that we can drop the /oldroot
temporary dir.
* when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or
so, freeze the payload too.
-* repart: support setting up dm-integrity with HMAC
-
* add /etc/integritytab, to support dm-integrity setups. In particular those
with HMAC as hash function, so that we can have a protected /home without
encryption (leaving encryption to the individual dirs/homed).
* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
exists and responds.
-* when systemd-nspawn and suchlike dissect an OS image, and there are multiple
- root partitions, do an strverscmp() on the partition label and boot
- first. That is inspired how sd-boot figures out which kernel to boot, and
- thus allows defining OS images which can be A/B updated and we default to the
- newest version automatically, both in nspawn and in sd-boot
-
-* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
- creates
-
* bootctl:
- teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
- teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
* systemd-repart: allow sizing partitions as factor of available RAM, so that
we can reasonably size swap partitions for hibernation.
-* systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
-
* systemd-repart: allow boolean option that ensures that if existing partition
doesn't exist within the configured size bounds the whole command fails. This
is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
"systemd-gdb" for attaching to the start-up of any system service in its
natural habitat.
-* gpt-auto logic: related to the above, maybe support a "secondary" root
- partition, that is mounted to / and is writable, and where the actual root's
- /usr is mounted into.
-
* gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
* drop nss-myhostname in favour of nss-resolve?
* journalctl: make sure -f ends when the container indicated by -M terminates
-* mount: automatically search for "main" partition of an image has multiple
- partitions
-
* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
find a way to map the User=/Group= of the service to the right name. This way
a user/group for a service only has to exist on the host for the right
discovered Windows installation might have the identifier `auto-windows` or
`auto-windows-10` or so.).
-4. Similar, boot menu entries referring to Apple MacOS X installations should
+4. Similar, boot menu entries referring to Apple macOS installations should
use the identifier `osx` or one that is prefixed with `osx-`. If such an
entry is automatically discovered by the boot loader use `auto-osx` as
identifier, or `auto-osx-` as prefix for the identifier, see above.
Note that these configurations snippets do not need to be the only configuration source for a boot loader. It may extend this list of entries with additional items from other configuration files (for example its own native configuration files) or automatically detected other entries without explicit configuration.
-To make this explicitly clear: this specification is designed with "free" operating systems in mind, starting Windows or MacOS is out of focus with these configuration snippets, use boot-loader specific solutions for that. In the text above, if we say "OS" we hence imply "free", i.e. primarily Linux (though this could be easily be extended to the BSDs and whatnot).

+8. Do not pass the `CAP_AUDIT_CONTROL`, `CAP_AUDIT_READ`, `CAP_AUDIT_WRITE`
+ capabilities to the container, in particular not to those making use of user
+ namespaces. The kernel's audit subsystem is still not virtualized for
+ containers, and passing these credentials is pointless hence, given the
+ actual attempt to make use of the audit subsystem will fail. Note that
+ systemd's audit support is partially conditioned on these capabilities, thus
+ by dropping them you ensure that you get an entirely clean boot, as systemd
+ will make no attempt to use it. If you pass the capabilities to the payload
+ systemd will assume that audit is available and works, and some components
+ will subsequently fail in various ways. Note that once the kernel learnt

+
+# Package Metadata for Core Files
+
+*Intended audience: hackers working on userspace subsystems that create ELF binaries
+or parse ELF core files.*
+
+## Motivation
+
+ELF binaries get stamped with a unique, build-time generated hex string identifier called
+`build-id`, [which gets embedded as an ELF note called `.note.gnu.build-id`](https://fedoraproject.org/wiki/Releases/FeatureBuildId).
+In most cases, this allows to associate a stripped binary with its debugging information.
+It is used, for example, to dynamically fetch DWARF symbols from a debuginfo server, or
+to query the local package manager and find out the package metadata or, again, the DWARF
+symbols or program sources.
+
+However, this usage of the `build-id` requires either local metadata, usually set up by
+the package manager, or access to a remote server over the network. Both of those might
+be unavailable or forbidden.
+
+Thus it becomes desirable to add additional metadata to a binary at build time, so that
+`systemd-coredump` and other services analyzing core files are able to extract said
+metadata simply from the core file itself, without external dependencies.
+
+## Implementation
+
+This document will attempt to define a common metadata format specification, so that
+multiple implementers might use it when building packages, or core file analyzers, and
+so on.
+
+The metadata will be embedded in a single, new ELF header section, in a key-value JSON
+format. Implementers working on parsing core files should not assume a specific list of
+keys, but parse anything that is included in the section.
+Implementers working on build tools should strive to use the same key names, for
+consistency. The most common will be listed here. When corresponding to the content of
+os-release, the values should match, again for consistency.
+
+If available, the metadata should also include the debuginfod server URL that can provide
+the original executable, debuginfo and sources, to further facilitate debugging.

This special requirement is made because `/var/` (unlike the other partition types listed here) is inherently private to a specific installation and cannot possibly be shared between multiple OS installations on the same disk, and thus should be bound to a specific instance of the OS, identified by its machine ID. If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/var`. |

## Partition Flags
-For the root, `/usr/`, server data, home, variable data, temporary data and swap
-partitions, the partition flag bit 63 ("*no-auto*") may be used to turn off
-auto-discovery for the specific partition. If set, the partition will not be
-automatically mounted or enabled.
-
-For the root, `/usr/`, server data, home, variable data and temporary data
-partitions, the partition flag bit 60 ("*read-only*") may be used to mark a
-partition for read-only mounts only. If set, the partition will be mounted
-read-only instead of read-write. Note that the variable data partition and the
-temporary data partition will generally not be able to serve their purpose if
-marked read-only, since by their very definition they are supposed to be
-mutable. (The home and server data partitions are generally assumed to be
-mutable as well, but the requirement for them is not equally strong.) Because
-of that, while the read-only flag is defined and supported, it's almost never a
-good idea to actually use it for these partitions.
-
-Note that these two flag definitions happen to map nicely to the ones used by
-Microsoft Basic Data Partitions.
+This specification defines three GPT partition flags that may be set for the
+partition types defined above:
+
+1. For the root, `/usr/`, Verity, home, server data, variable data, temporary data,
+ swap and extended boot loader partitions, the partition flag bit 63
+ ("*no-auto*") may be used to turn off auto-discovery for the specific
+ partition. If set, the partition will not be automatically mounted or
+ enabled.

+2. For the root, `/usr/`, Verity, home, server data, variable data, temporary
+ data and extended boot loader partitions, the partition flag bit 60
+ ("*read-only*") may be used to mark a partition for read-only mounts only.
+ If set, the partition will be mounted read-only instead of read-write. Note
+ that the variable data partition and the temporary data partition will
+ generally not be able to serve their purpose if marked read-only, since by
+ their very definition they are supposed to be mutable. (The home and server
+ data partitions are generally assumed to be mutable as well, but the
+ requirement for them is not equally strong.) Because of that, while the
+ read-only flag is defined and supported, it's almost never a good idea to
+ actually use it for these partitions. Also note that Verity partitions are
+ by their semantics always read-only. The flag is hence of little effect for
+ them, and it is recommended to set it unconditionally for the Verity
+ partition types.
+
+3. For the root, `/usr/`, home, server data, variable data, temporary data and
+ extended boot loader partitions, the partition flag bit 59
+ ("*grow-file-system*") may be used to mark a partition for automatic growing
+ of the contained file system to the size of the partition when
+ mounted. Tools that automatically mount disk image with a GPT partition
+ table are suggested to implicitly grow the contained file system to the
+ partition size they are contained in. This flag is without effect on
+ partitions marked read-only.
+
+Note that the first two flag definitions happen to map nicely to the ones used
+by Microsoft Basic Data Partitions.
+
+All three of these flags generally affect only auto-discovery and automatic
+mounting of disk images. If partitions marked with these flags are mounted
+using low-level commands like
+[mount(8)](https://man7.org/linux/man-pages/man2/mount.8.html) or directly with
+[mount(2)](https://man7.org/linux/man-pages/man2/mount.2.html), they typically
+have no effect.
## Suggested Mode of Operation
it _must_ take precedence over automatically discovered partitions. If a
`/home/`, `/usr/`, `/srv/`, `/boot/`, `/var/`, `/var/tmp/`, `/efi/` or `/boot/`
directory is found to be populated already in the root partition, the automatic
-discovery _must not_ mount any discovered file system over it.
+discovery _must not_ mount any discovered file system over it. Optionally, in
+case of the root, `/usr/` and their Verity partitions instead of strictly
+mounting the first suitable partition an OS might choose to mount the partition
+whose label compares the highest according to `strverscmp()` or a similar
+logic, in order to implement a simple partition-based A/B versioning
+scheme. The precise rules are left for the implementation to decide, but when
+in doubt earlier partitions (by their index) should always win over later
+partitions if the label comparison is inconclusive.
A *container* *manager* should automatically discover and mount the root,
`/usr/`, `/home/`, `/srv/`, `/var/`, `/var/tmp/` partitions inside a container
prefixed with `:` in which case the kernel command line option takes
precedence, if it is specified as well.

+# Native Journal Protocol
+
+`systemd-journald.service` accepts log data via various protocols:
+
+* Classic RFC3164 BSD syslog via the `/dev/log` socket
+* STDOUT/STDERR of programs via `StandardOutput=journal` + `StandardError=journal` in service files (both of which are default settings)
+* Kernel log messages via the `/dev/kmsg` device node
+* Audit records via the kernel's audit subsystem
+* Structured log messages via `journald`'s native protocol
+
+The latter is what this document is about: if you are developing a program and
+want to pass structured log data to `journald`, it's the Journal's native
+protocol what you want to use. The systemd project provides the
+[`sd_journal_print(3)`](https://www.freedesktop.org/software/systemd/man/sd_journal_print.html)
+API that implements the client side of this protocol. This document explains
+what this interface does behind the scenes, in case you'd like to implement a
+client for it yourself, without linking to `libsystemd` — for example because
+you work in a programming language other than C or otherwise want to avoid the
+dependency.
+
+## Basics
+
+The native protocol of `journald` is spoken on the
+`/run/systemd/journal/socket` `AF_UNIX`/`SOCK_DGRAM` socket on which
+`systemd-journald.service` listens. Each datagram sent to this socket
+encapsulates one journal entry that shall be written. Since datagrams are
+subject to a size limit and we want to allow large journal entries, datagrams
+sent over this socket may come in one of two formats:
+
+* A datagram with the literal journal entry data as payload, without
+ any file descriptors attached.
+
+* A datagram with an empty payload, but with a single
+ [`memfd`](https://man7.org/linux/man-pages/man2/memfd_create.2.html)
+ file descriptor that contains the literal journal entry data.
+
+Other combinations are not permitted, i.e. datagrams with both payload and file
+descriptors, or datagrams with neither, or more than one file descriptor. Such
+datagrams are ignored. The `memfd` file descriptor should be fully sealed. The
+binary format in the datagram payload and in the `memfd` memory is
+identical. Typically a client would attempt to first send the data as datagram
+payload, but if this fails with an `EMSGSIZE` error it would immediately retry
+via the `memfd` logic.
+
+A client probably should bump up the `SO_SNDBUF` socket option of its `AF_UNIX`
+socket towards `journald` in order to delay blocking I/O as much as possible.
+
+## Data Format
+
+Each datagram should consist of a number of environment-like key/value
+assignments. Unlike environment variable assignments the value may contain NUL
+bytes however, as well as any other binary data. Keys may not include the `=`
+or newline characters (or any other control characters or non-ASCII characters)
+and may not be empty.
+
+Serialization into the datagram payload or `memfd` is straight-forward: each
+key/value pair is serialized via one of two methods:
+
+* The first method inserts a `=` character between key and value, and suffixes
+the result with `\n` (i.e. the newline character, ASCII code 10). Example: a
+key `FOO` with a value `BAR` is serialized `F`, `O`, `O`, `=`, `B`, `A`, `R`,
+`\n`.
+
+* The second method should be used if the value of a field contains a `\n`
+byte. In this case, the key name is serialized as is, followed by a `\n`
+character, followed by a (non-aligned) little-endian unsigned 64bit integer
+encoding the size of the value, followed by the literal value data, followed by
+`\n`. Example: a key `FOO` with a value `BAR` may be serialized using this
+second method as: `F`, `O`, `O`, `\n`, `\003`, `\000`, `\000`, `\000`, `\000`,
+`\000`, `\000`, `\000`, `B`, `A`, `R`, `\n`.
+
+If the value of a key/value pair contains a newline character (`\n`), it *must*
+be serialized using the second method. If it does not, either method is
+permitted. However, it is generally recommended to use the first method if
+possible for all key/value pairs where applicable since the generated datagrams
+are easily recognized and understood by the human eye this way, without any
+manual binary decoding — which improves the debugging experience a lot, in
+particular with tools such as `strace` that can show datagram content as text
+dump. After all, log messages are highly relevant for debugging programs, hence
+optimizing log traffic for readability without special tools is generally
+desirable.
+
+Note that keys that begin with `_` have special semantics in `journald`: they
+are *trusted* and implicitly appended by `journald` on the receiving
+side. Clients should not send them — if they do anyway, they will be ignored.
+
+The most important key/value pair to send is `MESSAGE=`, as that contains the
+actual log message text. Other relevant keys a client should send in most cases
+are `PRIORITY=`, `CODE_FILE=`, `CODE_LINE=`, `CODE_FUNC=`, `ERRNO=`. It's
+recommended to generate these fields implicitly on the client side. For further
+information see the [relevant documentation of these
+fields](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html).
+
+The order in which the fields are serialized within one datagram is undefined
+and may be freely chosen by the client. The server side might or might not
+retain or reorder it when writing it to the Journal.
+
+Some programs might generate multi-line log messages (e.g. a stack unwinder
+generating log output about a stack trace, with one line for each stack
+frame). It's highly recommended to send these as a single datagram, using a
+single `MESSAGE=` field with embedded newline characters between the lines (the
+second serialization method described above must hence be used for this
+field). If possible do not split up individual events into multiple Journal
+events that might then be processed and written into the Journal as separate
+entries. The Journal toolchain is capable of handling multi-line log entries
+just fine, and it's generally preferred to have a single set of metadata fields
+associated with each multi-line message.
+
+Note that the same keys may be used multiple times within the same datagram,
+with different values. The Journal supports this and will write such entries to
+disk without complaining. This is useful for associating a single log entry
+with multiple suitable objects of the same type at once. This should only be
+used for specific Journal fields however, where this is expected. Do not use
+this for Journal fields where this is not expected and where code reasonably
+assumes per-event uniqueness of the keys. In most cases code that consumes and
+displays log entries is likely to ignore such non-unique fields or only
+consider the first of the specified values. Specifically, if a Journal entry
+contains multiple `MESSAGE=` fields, likely only the first one is
+displayed. Note that a well-written logging client library thus will not use a
+plain dictionary for accepting structured log metadata, but rather a data
+structure that allows non-unique keys, for example an array, or a dictionary
+that optionally maps to a set of values instead of a single value.
+
+## Example Datagram
+
+Here's an encoded message, with various common fields, all encoded according to
+the first serialization method, with the exception of one, where the value
+contains a newline character, and thus the second method is needed to be used.
+
+```
+PRIORITY=3\n
+SYSLOG_FACILITY=3\n
+CODE_FILE=src/foobar.c\n
+CODE_LINE=77\n
+BINARY_BLOB\n
+\004\000\000\000\000\000\000\000xx\nx\n
+CODE_FUNC=some_func\n
+SYSLOG_IDENTIFIER=footool\n
+MESSAGE=Something happened.\n
+```
+
+(Lines are broken here after each `\n` to make things more readable. C-style
+backslash escaping is used.)
+
+## Automatic Protocol Upgrading
+
+It might be wise to automatically upgrade to logging via the Journal's native
+protocol in clients that previously used the BSD syslog protocol. Behaviour in
+this case should be pretty obvious: try connecting a socket to
+`/run/systemd/journal/socket` first (on success use the native Journal
+protocol), and if that fails fall back to `/dev/log` (and use the BSD syslog
+protocol).
+
+Programs normally logging to STDERR might also choose to upgrade to native
+Journal logging in case they are invoked via systemd's service logic, where
+STDOUT and STDERR are going to the Journal anyway. By preferring the native
+protocol over STDERR-based logging, structured metadata can be passed along,
+including priority information and more — which is not available on STDERR
+based logging. If a program wants to detect automatically whether its STDERR is
+connected to the Journal's stream transport, look for the `$JOURNAL_STREAM`
+environment variable. The systemd service logic sets this variable to a
+colon-separated pair of device and inode number (formatted in decimal ASCII) of
+the STDERR file descriptor. If the `.st_dev` and `.st_ino` fields of the
+`struct stat` data returned by `fstat(STDERR_FILENO, …)` match these values a
+program can be sure its STDERR is connected to the Journal, and may then opt to
+upgrade to the native Journal protocol via an `AF_UNIX` socket of its own, and
+cease to use STDERR.
+
+Why bother with this environment variable check? A service program invoked by
+systemd might employ shell-style I/O redirection on invoked subprograms, and
+those should likely not upgrade to the native Journal protocol, but instead
+continue to use the redirected file descriptors passed to them. Thus, by
+comparing the device and inode number of the actual STDERR file descriptor with
+the one the service manager passed, one can make sure that no I/O redirection
+took place for the current program.
+
+## Alternative Implementations
+
+If you are looking for alternative implementations of this protocol (besides
+systemd's own in `sd_journal_print()`), consider
+[GLib's](https://gitlab.gnome.org/GNOME/glib/-/blob/master/glib/gmessages.c) or
+[`dbus-broker`'s](https://github.com/bus1/dbus-broker/blob/main/src/util/log.c).

+# Description
+#
+# Each node on IEEE 1394 bus has configuration ROM with information for identification. Although the
+# typical content of configuration ROM is defined by 1394 Trading Association, many nodes have own
+# quirks. This database includes supplemental information to unit in the node.
+
+# Convention
+#
+# One entry has two keys. One is customized key to match a node. Another is for kernel alias to
+# match an unit included in the node.
+#
+# The customized key has two formats according to whether the node has model attribute:
+# - ven0x000000mo0x000000units0x000000:0x000000
+# - ven0x000000units0x000000:0x000000
+#
+# Even when the node has multiple units, the entry should match to one of the units. In the case,
+# the customized key should have wild pattern for units field:
+# - ven0x000000mo0x000000units*0x000000:0x000000*
+# - ven0x000000units*0x000000:0x000000*
+#
+# The hexadecimal digits part of the customized key should be lower-case. Linux FireWire subsystem
+# uses lower-case value for attributes of sysfs node, and systemd-hwdb parses the custom key by
+# case-sensitive way. On the other hand, it parses kernel alias by case-insensitive way.
+#
+# The entry should have some of IEEE1394_UNIT_FUNCTION_XXX environment variables to express function
+# of the unit. The variables are used to decide group owner of special file for character device
+# corresponding to node including the unit. At present, below variables are supported:
+# - IEEE1394_UNIT_FUNCTION_MIDI
+# - For any unit to process MIDI messages. For example, the unit includes AV/C music subunit.
+# - IEEE1394_UNIT_FUNCTION_AUDIO
+# - For any unit to process audio signal. For example, the unit includes AV/C audio subunit.
+# - IEEE1394_UNIT_FUNCTION_VIDEO
