This deprecates IPForward= setting, which unconditionally controled
the global setting, even though it is a setting in .network file.
Instead, this introduces new IPv4Forwarding= and IPv6Forwarding=
settings both in .network and networkd.conf.
If these settings are specified in a .network file, then the
per-interface forwarding setting will be configured.
If specified in networkd.conf, then the global IP forwarding setting will
be configured.
Closes#30648.
Allow to set the broadcast queueing threshold
on macvlan devices. This controls which multicast packets will be
processed in a workqueue instead of inline.
This renames a few of the switches vmspawn takes, such as --qemu-mem=
and --qemu-smp= to names without the "qemu" moniker and uses less
cryptic names (i.e. --ram= and --cpus=).
I think it's a bit unsystematic that so far we use the "qemu" prefix for
some options but not for others. At least I could not figure out a
system when we use it and when we don't. Hence let's clean it up and
just use simpler names without suffix.
After all we might want to plug other hypervisors behind vmspawn one
day, hence I think there's value in sticking to generic names for these
switches that allow us to switch out backends easily. In particular for
--ram= and --cpus= which are probably the most fundamental of VM settings
there are.
The old switches are support for compat, but not advertised in man page
or --help text anymore.
I left "--qemu-gui" under its current name, since it fundamentally is a
a qemu concept, exposing a qemu specific graphical UI.
If specified we'll not try to find a free V, but instead just output
directly to the specified TTY. This is particularly useful for
debugging, as it means "systemd-bsod --tty=/dev/tty" just works.
The command will refuse to write to a TTY, so give a strong hint
that redirecting to a file is recommended. This makes the synopsis,
man page text, and --help output consistent.
Also drop the space after the redirection operator everywhere.
Let's bring the credentials into a better order, in order of relevance.
Also, let's clarify what the generic LUKS PIN is about.
Finally, list the credentials in system-credentials(7) too, after all
people might want to unlock a disk with this via SMBIOS Type 11 or so.
Precedence for example in ac63c8df30/rules.d/99-systemd.rules.in (L75).
Add ENV to the list of keys where string substitutions can be used.
While I'm at it, also sort the list in that paragraph alphabetically.
This makes it possible to edit blob directories using homectl. The
following syntax is available:
* `--blob-directory=/path/somewhere`: Replaces the entire blob directory
with the contents of /path/somewhere
* `--blob-directory=foobar=/path/somewhere`: Replaces just the file
foobar in the blob directory with the contents of /path/somewhere
* `--blob-directory=foobar=`: Deletes the file foobar from the blob
directory
* `--blob-directory=`: Resets all previous flags
* `--avatar=`, etc: Shortcuts for `--blob-directory=FILENAME=` for the
known files in the blob directory
Introduces new extended variants of the various incarnations of
Create and Update, which take a map of filenames to FDs. This map is
then used to populate the bulk directory.
FDs are used to prevent the client from abusing homed's blob directory
permissions (everything is made world-readable by homed) to open files
that they normally aren't allowed to open. Passing along an FD ensures
that the client has read access to the file it wants homed to make
world-readable.
Internally, homework uses the map to overwrite the system blob dir.
Later, homework's existing blob dir reconciliation logic will propagate
the new contents from the system blob dir into the embedded blob
dir
This ensures that a user-specific blob directory exists in
/var/cache/systemd/homed for as long as the user exists, and gets
deleted if the user gets deleted.
It also advertises this blob directory via the user record, so that
clients can find and use it.
Allows to configure bond arp_missed_max is the maximum number of arp_interval monitor cycle
for missed ARP replies. If this number is exceeded, link is reported as
down.
In case the D-Bus policy is not set up correctly the example just
loops forever. Check the return of sd_bus_request_name_async() in
a callback and exit if the error is not temporary.

This commit adds a new way of forwarding journal messages - forwarding
over a socket.
The socket can be any of AF_INET, AF_INET6, AF_UNIUX or AF_VSOCK.
The address to connect to is retrieved from the "journald.forward_address" credential.
It can also be specified in systemd-journald's unit file with ForwardAddress=
owneridmap bind option will map the target directory owner from inside the
container to the owner of the directory bound from the host filesystem.
This will ensure files and directories created in the container will be owned
by the directory owner of the host filesystem. All other users will remain
unmapped. Files to be written as other users in the container will not be
allowed.
Resolves: #27037
This field is like preferredLanguage, but takes a priority list of
languages instead. If an app isn't translated into a user's primary
language, it can fall back to one of the other languages in the list
thus making the app more accessible to the user.
For instance: in my experience, many Ukrainians are fluent in Russian,
often significantly better than English (especially if they are of a
generation that grew up during the USSR). Such a person might set this
new variable to ["uk_UA.UTF-8", "ru_UA.UTF-8"] so that software that
lacks Ukrainian translations will first try Russian translations before
defaulting to English.
Fixes#31290
cryptsetup 2.7.0 adds feature to link effective volume key in custom
kernel keyring during device activation. It can be used later to pass
linked volume key to other services.
For example: kdump enabled systems installed on LUKS2 device.
This feature allows it to store volume key linked in a kernel keyring
to the kdump reserved memory and reuse it to reactivate LUKS2 device
in case of kernel crash.
OOMPolicy in scope units is separately supported in
version v253, so I think it cannot be directly used
in the manpage with the version from the service.
fix:#30836
The idea is simple: skip the final operation that creates or removes things
or changes the attributes, but otherwise go through the rest of the code.
This results in quite a lot of fairly repetitive conditions in the low-level
code. Another approach would be to print earlier, at a higher level, but then
we'd have less precise information about what is about to happen.
