systemd System and Service Manager
-CHANGES WITH 246 in spe:
+CHANGES WITH 246:
* The service manager gained basic support for cgroup v2 freezer. Units
can now be suspended or resumed either using new systemctl verbs,
* .socket units gained a new boolean setting PassPacketInfo=. If
enabled, the kernel will attach additional per-packet metadata to all
- packets read from the socket, as ancillary message. This controls the
- IP_PKTINFO, IPV6_RECVPKTINFO, NETLINK_PKTINFO socket options,
+ packets read from the socket, as an ancillary message. This controls
+ the IP_PKTINFO, IPV6_RECVPKTINFO, NETLINK_PKTINFO socket options,
depending on socket type.
* .service units gained a new setting RootHash= which may be used to
* Most options in systemd that accept hexadecimal values prefixed with
0x in additional to the usual decimal notation now also support octal
- notation when he 0o prefix is used and binary notation if the 0b
+ notation when the 0o prefix is used and binary notation if the 0b
prefix is used.
+ * Various command line parameters and configuration file settings that
+ configure key or certificate files now optionally take paths to
+ AF_UNIX sockets in the file system. If configured that way a stream
+ connection is made to the socket and the required data read from
+ it. This is a simple and natural extension to the existing regular
+ file logic, and permits other software to provide keys or
+ certificates via simple IPC services, for example when unencrypted
+ storage on disk is not desired. Specifically, systemd-networkd's
+ Wireguard and MACSEC key file settings as well as
+ systemd-journal-gatewayd's and systemd-journal-remote's PEM
+ key/certificate parameters support this now.
+
* Unit files, tmpfiles.d/ snippets, sysusers.d/ snippets and other
configuration files that support specifier expansion learnt six new
specifiers: %a resolves to the current architecture, %o/%w/%B/%W
from the documentation, but will now result in warnings when used,
and be converted to "journal" and "journal+console" automatically.
+ * If the service setting User= is set to the "nobody" user, a warning
+ message is now written to the logs (but the value is nonetheless
+ accepted). Setting User=nobody is unsafe, since the primary purpose
+ of the "nobody" user is to own all files whose owner cannot be mapped
+ locally. It's in particular used by the NFS subsystem and in user
+ namespacing. By running a service under this user's UID it might get
+ read and even write access to all these otherwise unmappable files,
+ which is quite likely a major security problem.
+
+ * tmpfs mounts automatically created by systemd (/tmp, /run, /dev/shm,
+ and others) now have a size and inode limits applied (50% of RAM for
+ /tmp, 10% of RAM for /dev/shm, etc.)
+
+ * nss-mymachines lost support for resolution of users and groups, and
+ now only does resolution of hostnames. This functionality is now
+ provided by nss-systemd. Thus, the 'mymachines' entry should be
+ removed from the 'passwd:' and 'group:' lines in /etc/nsswitch.conf
+ (and 'systemd' added if it is not already there).
+
* A new kernel command line option systemd.hostname= has been added
that allows controlling the hostname that is initialized early during
boot.
enabled by default, please submit a patch that adds it to the
database (see /usr/lib/udev/hwdb.d/60-autosuspend.hwdb).
- * systemd-udevd gained new configuration option timeout_signal= as well
- as corresponding kernel command line option udev.timeout_signal=.
+ * systemd-udevd gained the new configuration option timeout_signal= as well
+ as a corresponding kernel command line option udev.timeout_signal=.
The option can be used to configure the UNIX signal that the main
daemon sends to the worker processes on timeout. Setting the signal
to SIGABRT is useful for debugging.
RxMiniBufferSize= and RxJumboBufferSize= in order to configure jumbo
frame ring buffer sizes.
+ * networkd.conf gained a new boolean setting ManageForeignRoutes=. If
+ enabled systemd-networkd manages all routes configured by other tools.
+
+ * .network files managed by systemd-networkd gained a new section
+ [SR-IOV], in order to configure SR-IOV capable network devices.
+
* systemd-networkd's [IPv6Prefix] section in .network files gained a
new boolean setting Assign=. If enabled an address from the prefix is
automatically assigned to the interface.
+ * systemd-networkd gained a new section [DHCPv6PrefixDelegation] which
+ controls delegated prefixes assigned by DHCPv6 client. The section
+ has three settings: SubnetID=, Assign=, and Token=. The setting
+ SubnetID= allows explicit configuration of the preferred subnet that
+ systemd-networkd's Prefix Delegation logic assigns to interfaces. If
+ Assign= is enabled (which is the default) an address from any acquired
+ delegated prefix is automatically chosen and assigned to the
+ interface. The setting Token= specifies an optional address generation
+ mode for Assign=.
+
* systemd-networkd's [Network] section gained a new setting
- IPv6PDSubnetId= that allows explicit configuration of the preferred
- subnet that networkd's Prefix Delegation logic assigns to an
- interfaces.
+ IPv4AcceptLocal=. If enabled the interface accepts packets with local
+ source addresses.
* systemd-networkd gained support for configuring the HTB queuing
discipline in the [HierarchyTokenBucket] and
[DeficitRoundRobinSchedulerClass], "BFIFO" in [BFIFO],
"PFIFOHeadDrop" in [PFIFOHeadDrop], "PFIFOFast" in [PFIFOFast], "HHF"
in [HeavyHitterFilter], "ETS" in [EnhancedTransmissionSelection] and
- "QFQ" in [QuickFairQueueingClass].
+ "QFQ" in [QuickFairQueueing] and [QuickFairQueueingClass].
* systemd-networkd gained support for a new Termination= setting in the
[CAN] section for configuring the termination resistor. It also
traffic). DataBitRate=, DataSamplePoint=, FDMode=, FDNonISO= have
been added to configure various CAN-FD aspects.
- * systemd-networkd's [DHCPv6] section gained a new WithoutRA= boolean
- setting. If enabled, DHCPv6 will be attempted right-away without
- requiring an Router Advertisement packet suggesting it
- first. Conversely, the [IPv6AcceptRA] gained a boolean option
+ * systemd-networkd's [DHCPv6] section gained a new option WithoutRA=.
+ When enabled, DHCPv6 will be attempted right-away without requiring an
+ Router Advertisement packet suggesting it first (i.e. without the 'M'
+ or 'O' flags set). The [IPv6AcceptRA] section gained a boolean option
DHCPv6Client= that may be used to turn off the DHCPv6 client even if
the RA packets suggest it.
Description"). Support for "MUD" URLs was also added to the LLDP
stack, configurable in the [LLDP] section in .network files.
+ * The Mode= settings in [MACVLAN] and [MACVTAP] now support 'source'
+ mode. Also, the sections now support a new setting SourceMACAddress=.
+
* systemd-networkd's .netdev files now support a new setting
VLANProtocol= in the [Bridge] section that allows configuration of
the VLAN protocol to use.
* systemd-networkd supports a new Group= setting in the [Link] section
of the .network files, to control the link group.
+ * systemd-networkd's [Network] section gained a new
+ IPv6LinkLocalAddressGenerationMode= setting, which specifies how IPv6
+ link local address is generated.
+
* A new default .network file is now shipped that matches TUN/TAP
devices that begin with "vt-" in their name. Such interfaces will
have IP routing onto the host links set up automatically. This is
interface which is fully set up for host communication, simply by
carefully picking an interface name to use.
- * A new boolean option AssignAcquiredDelegatedPrefixAddress= has been
- added to the [DHCPv6] section of .network files. If enabled (which is
- the default) an address from any acquired delegated prefix is
- automatically chosen and assigned to the interface.
+ * systemd-networkd's [DHCPv6] section gained a new setting RouteMetric=
+ which sets the route priority for routes specified by the DHCP server.
+
+ * systemd-networkd's [DHCPv6] section gained a new setting VendorClass=
+ which configures the vendor class information sent to DHCP server.
* The BlackList= settings in .network files' [DHCPv4] and
[IPv6AcceptRA] sections have been renamed DenyList=. The old names
interface. There are new "up" and "down" commands to bring specific
interfaces up or down.
- * systemd-resolved's DNS= configuration option now optionally accepts
- DNS server addresses suffixed by "#" followed by a host name. If
- used, the DNS-over-TLS certificate is validated to match the
- specified hostname.
+ * systemd-resolved's DNS= configuration option now optionally accepts a
+ port number (after ":") and a host name (after "#"). When the host
+ name is specified, the DNS-over-TLS certificate is validated to match
+ the specified hostname. Additionally, in case of IPv6 addresses, an
+ interface may be specified (after "%").
* systemd-resolved may be configured to forward single-label DNS names.
This is not standard-conformant, but may make sense in setups where
MESSAGE=. This is useful to retrieve a very specific set of fields
without any decoration.
+ * The sd-journal.h API gained two new functions:
+ sd_journal_enumerate_available_unique() and
+ sd_journal_enumerate_available_data() that operate like their
+ counterparts that lack the _available_ in the name, but skip items
+ that cannot be read and processed by the local implementation
+ (i.e. are compressed in an unsupported format or such),
+
* coredumpctl gained a new --file= switch, matching the same one in
journalctl: a specific journal file may be specified to read the
coredump data from.
storage and file system may now be configured explicitly, too, via
the new /etc/systemd/homed.conf configuration file.
+ * systemd-homed now supports unlocking home directories with FIDO2
+ security tokens that support the 'hmac-secret' extension, in addition
+ to the existing support for PKCS#11 security token unlocking
+ support. Note that many recent hardware security tokens support both
+ interfaces. The FIDO2 support is accessible via homectl's
+ --fido2-device= option.
+
+ * homectl's --pkcs11-uri= setting now accepts two special parameters:
+ if "auto" is specified and only one suitable PKCS#11 security token
+ is plugged in, its URL is automatically determined and enrolled for
+ unlocking the home directory. If "list" is specified a brief table of
+ suitable PKCS#11 security tokens is shown. Similar, the new
+ --fido2-device= option also supports these two special values, for
+ automatically selecting and listing suitable FIDO2 devices.
+
* The /etc/crypttab tmp option now optionally takes an argument
selecting the file system to use. Moreover, the default is now
changed from ext2 to ext4.
control the inode limit for the per-user $XDG_RUNTIME_DIR tmpfs
instance.
- * systemd-firstboot gained a new --root-password-hashed= parameter for
- setting the root user's password as UNIX password hash. There's a new
- --delete-root-password switch which instead of setting a password for
- the root user, removes it so that log-in without a password is
- permitted. There's now --force which if specified means any existing
- configuration is overwritten by the specified settings. It also
- gained a new --kernel-command-line= parameter which may be used to
- set the /etc/kernel/cmdline file of an OS image.
-
* A new generator systemd-xdg-autostart-generator has been added. It
generates systemd unit files from XDG autostart .desktop files, and
may be used to let the systemd user instance manage services that are
started automatically as part of the desktop session.
- * "booctl" gained a new verb "reboot-to-firmware" that may be used
- to query and change the firmware's reboot into firmware setup flag.
+ * "bootctl" gained a new verb "reboot-to-firmware" that may be used
+ to query and change the firmware's 'reboot into firmware' setup flag.
* systemd-firstboot gained a new switch --kernel-command-line= that may
be used to initialize the /etc/kernel/cmdline file of the image. It
also gained a new switch --root-password-hashed= which is like
--root-password= but accepts a pre-hashed UNIX password as
argument. The new option --delete-root-password may be used to unset
- any password for the root user (dangerous!). A new --force option may
- be used to override any already set settings with the parameters
- specified on the command line (by default, the tool will not override
- what has already been set before, i.e. is purely incremental).
+ any password for the root user (dangerous!). The --root-shell= switch
+ may be used to control the shell to use for the root account. A new
+ --force option may be used to override any already set settings with
+ the parameters specified on the command line (by default, the tool
+ will not override what has already been set before, i.e. is purely
+ incremental).
+
+ * systemd-firstboot gained support for a new --image= switch, which is
+ similar to --root= but accepts the path to a disk image file, on
+ which it then operates.
* A new sd-path.h API has been added to libsystemd. It provides a
simple API for retrieving various search paths and primary
document the methods, signals and properties.
* The expectations on user/group name syntax are now documented in
- detail; documentation how classic home directories may be converted
- into home directories managed by homed has been added; documentation
- regarding integration of homed/userdb functionality in desktops has
- been added:
+ detail; documentation on how classic home directories may be
+ converted into home directories managed by homed has been added;
+ documentation regarding integration of homed/userdb functionality in
+ desktops has been added:
https://systemd.io/USER_NAMES
https://systemd.io/CONVERTING_TO_HOMED
https://systemd.io/JOURNAL_FILE_FORMAT
+ * The interface for containers (https://systemd.io/CONTAINER_INTERFACE)
+ has been extended by a set of environment variables that expose
+ select fields from the host's os-release file to the container
+ payload. Similarly, host's os-release files can be mounted into the
+ container underneath /run/host. Together, those mechanisms provide a
+ standardized way to expose information about the host to the
+ container payload. Both interfaces are implemented in systemd-nspawn.
+
* All D-Bus services shipped in systemd now implement the generic
LogControl1 D-Bus API which allows clients to change log level +
target of the service during runtime.
+ * Only relevant for developers: the mkosi.default symlink has been
+ dropped from version control. Please create a symlink to one of the
+ distribution-specific defaults in .mkosi/ based on your preference.
