CHANGES WITH 235:

|

* modprobe.d drop-in is now shipped by default that sets bonding module
|
||||
option max_bonds=0. This overrides the kernel default, to avoid
|
||||
conflicts and ambiguity as to whether or not bond0 should be managed
|
||||
by networkd or not. This resolves multiple bugs of bond0 properties
|
||||
not being applied, when bond0 is configured with
|
||||
networkd. Distributors may choose to not package this, however in
|
||||
that case users will be prevented from correctly managing bond0
|
||||
interface using networkd.

|

which print the logging level and target of the system manager,

"set-log-target" verbs, which can be used to change those values.
|
||||
|

* systemd-networkd .network DHCP setting UseMTU default has changed
|
||||
from false to true. Meaning, DHCP server advertised mtu setting is
|
||||
from false to true. Meaning, DHCP server advertised MTU setting is
|
||||
now applied by default. This resolves networking issues on low-mtu
|
||||
networks.
|
||||
|
||||
* journald.conf gained a new boolean setting ReadKMsg= which defaults
|
||||
to on. If turned off kernel log messages will not be read by
|
||||
systemd-journald and not be included in the logs. It also gained a
|
||||
new setting LineMax= for configuring the maximum line length to allow
|
||||
when converting STDOUT/STDERR log streams into individual log
|
||||
records. The new default for this value is 48K, up from the previous
|
||||
hardcoded 4K.
|
||||
|
||||
* A new setting RuntimeDirectoryPreserve= for units has been added,
|
||||
which allows more detailed control of what to do with a runtime
|
||||
directory configured with RuntimeDirectory= (i.e. a directory below
|
||||
/run or $XDG_RUNTIME_DIR) after a unit is stopped.
|
||||
|
||||
* The RuntimeDirectory= setting for units gained support for creating
|
||||
deeper subdirectories below /run or $XDG_RUNTIME_DIR, instead of just
|
||||
one top-level directory.
|
||||
|
||||
* Units gained new options StateDirectory=, CacheDirectory=,
|
||||
LogsDirectory= and ConfigurationDirectory= which are closely related
|
||||
to RuntimeDirectory= but manage per-service directories below
|
||||
/var/lib, /var/cache, /var/log and /etc. By making use of this it is
|
||||
possible to write unit files which when activated automatically gain
|
||||
properly owned service specific directories in these locations, thus
|
||||
making unit files self-contained and increasing compatibility with
|
||||
stateless systems and factory reset where /etc or /var are
|
||||
unpopulated at boot. Matching these new settings there's also
|
||||
StateDirectoryMode=, CacheDirectoryMode=, LogsDirectoryMode=,
|
||||
ConfigurationDirectoryMode= for configuring the access mode of these
|
||||
directories.
|
||||
|
||||
* Automake support has been removed from this release. systemd is now
|
||||
Meson-only.
|
||||
|
||||
* systemd-journald will now aggressively cache client metadata during
|
||||
runtime, speeding up log write performance under pressure. This comes
|
||||
at a small price though: as much of the metadata is read
|
||||
asynchronously from /proc/ (and isn't implicitly attached to log
|
||||
datagrams by the kernel, like UID/GID/PID/SELinux are) this means the
|
||||
metadata stored alongside a log entry might be slightly
|
||||
out-of-date. Previously it could only be slightly newer than the log
|
||||
message. The time window is small however, and given that the kernel
|
||||
is unlikely to be improved anytime soon in this regard, this appears
|
||||
acceptable to us.
|
||||
|
||||
* nss-myhostname/systemd-resolved will now by default synthesize an
|
||||
A/AAAA resource record for the "_gateway" hostname, pointing to the
|
||||
current default IP gateway. Previously it did that for the "gateway"
|
||||
name, hampering adoption, as some distributions wanted to leave that
|
||||
host name open for local use. The old behaviour may still be
|
||||
requested at build time.
|
||||
|
||||
* systemd-networkd's [Address] section in .network files gained a new
|
||||
Scope= setting for configuring the IP address scope. The [Network]
|
||||
section gained a new boolean setting ConfigureWithoutCarrier= that
|
||||
tells systemd-networkd to ignore link sensing when configuring the
|
||||
device. The [DHCP] section gained a new Anonymize= boolean option for
|
||||
turning on a number of options suggested in RFC 7844. A new
|
||||
[RoutingPolicyRule] section has been added for configuring the IP
|
||||
routing policy. The [Route] section has gained support for a new
|
||||
Type= setting which permits configuring
|
||||
blackhole/unreachable/prohibit routes.
|
||||
|
||||
* The [VRF] section in .netdev files gained a new Table= setting for
|
||||
configuring the routing table to use. The [Tunnel] section gained a
|
||||
new Independent= boolean field for configuring tunnels independent of
|
||||
an underlying network interface. The [Bridge] section gained a new
|
||||
GroupForwardMask= option for configuration of propagation of link
|
||||
local frames between bridge ports.
|
||||
|
||||
* The WakeOnLan= setting in .link files gained support for a number of
|
||||
new modes. A new TCP6SegmentationOffload= setting has been added for
|
||||
configuring TCP/IPv6 hardware segmentation offload.
|
||||
|
||||
* The IPv6 RA sender implementation may now optionally send out RDNSS
|
||||
and RDNSSL records for supplying DNS configuration to peers.
|
||||
|
||||
* systemd-nspawn gained support for a new --system-call-filter= command
|
||||
line option for adding/removing entries in the default system call
|
||||
filter it applies. Moreover systemd-nspawn has been changed to
|
||||
implement a system call whitelist instead of a blacklist.
|
||||
|
||||
* systemd-run gained support for a new --pipe command line option. If
|
||||
used the STDIN/STDOUT/STDERR file descriptors passed to systemd-run
|
||||
are directly passed on to the activated transient service
|
||||
binary. This allows invoking arbitrary processes as systemd services
|
||||
(for example to take benefit of dependency management, accounting
|
||||
management, resource management or log management that is done
|
||||
automatically for services) — while still allowing them to be
|
||||
integrated in a classic UNIX shell pipeline.
|
||||
|
||||
* When a service sends RELOAD=1 via sd_notify() and reload propagation
|
||||
using ReloadPropagationTo= is configured, a reload is now propagated
|
||||
to configured units. (Previously this was only done on explicitly
|
||||
requested reloads, using "systemctl reload" or an equivalent
|
||||
command.)
|
||||
|
||||
* For each service unit a restart counter is now kept: it is increased
|
||||
each time the service is restarted due to Restart=, and may be
|
||||
queried using "systemctl show -p NRestarts …".
|
||||
|
||||
* New system call filter groups @setuid, @credentials, @memlock,
|
||||
@signal and @timer have been added, for usage with SystemCallFilter=
|
||||
in unit files and the new --system-call-filter= command line option
|
||||
of systemd-nspawn (see above).
|
||||
|
||||
* ExecStart= lines in unit files gained two new modifiers: when a
|
||||
command line is prefixed with "!" the command will be executed as
|
||||
configured, except for the credentials applied by
|
||||
setuid()/setgid()/setgroups(). It is very similar to the pre-existing
|
||||
"+", but does still apply namespacing options unlike "+". There's
|
||||
also "!!" now, which is mostly identical, but becomes a NOP on
|
||||
systems that support ambient capabilities. This is useful to write
|
||||
unit files that work with ambient capabilities where possible but
|
||||
automatically fall back to traditional privilege dropping mechanisms
|
||||
on systems where this is not supported.
|
||||
|
||||
* ListenNetlink= settings in socket units now support RDMA netlink
|
||||
sockets.
|
||||
|
||||
* A new unit file setting LockPersonality= has been added which permits
|
||||
locking down the chosen execution domain ("personality") of a service
|
||||
during runtime.
|
||||
|
||||
* A new special target "getty-pre.target" has been added, which is
|
||||
ordered before all text logins, and may be used to order services
|
||||
before, that shall run before these textual logins acquire access to
|
||||
the console.
|
||||
|
||||
* systemd will now attempt to load the virtio-rng.ko kernel module very
|
||||
early on if a VM environment supporting this is detected. This should
|
||||
improve entropy during early boot in virtualized environments.
|
||||
|
||||
* A _netdev option is now supported in /etc/crypttab that operates in a
|
||||
similar way as the same option in /etc/fstab: it permits configuring
|
||||
encrypted devices that need to be ordered after the network coming
|
||||
up. Following this logic, two new special targets
|
||||
remote-cryptsetup-pre.target and remote-cryptsetup.target have been
|
||||
added that are to cryptsetup.target what
|
||||
remote-fs.target/remote-fs-pre.target are to local-fs.target.
|
||||
|
||||
* Service units gained a new UnsetEnvironment= setting which permits
|
||||
unsetting specific environment variables for specific services that
|
||||
are normally passed to it (for example in order to mask out locale
|
||||
settings for specific services that can't deal with it).
|
||||
|
||||
* Units acquired a new boolean option IPAccounting=. When turned on, IP
|
||||
traffic accounting (packet count as well as byte count) is done for
|
||||
the service, and shown as part of "systemctl status" or "systemd-run
|
||||
--wait".
|
||||
|
||||
* Service units acquired two new options IPAddressAllow= and
|
||||
IPAddressDeny=, taking a list of IPv4 or IPv6 addresses and masks,
|
||||
for configuring a simple IP access control list for all sockets of
|
||||
the unit. These options are available also on .slice and .socket
|
||||
units, permitting flexible access list configuration for individual
|
||||
services as well as groups of services (as defined by a slice unit),
|
||||
including system-wide. Note that IP ACLs configured this way are
|
||||
enforced on every single IPv4 and IPv6 socket created by any process
|
||||
of the service unit, and apply to ingress as well as egress traffic.
|
||||
|
||||
* If CPUAccounting= or IPAccounting= is turned on for a unit a new,
|
||||
recognizable log message is generated each time the unit is stopped,
|
||||
containing information about the consumed resources of this
|
||||
invocation.
|
||||
|
||||
* A new setting KeyringMode= has been added to unit files, which may be
|
||||
used to control how the kernel keyring is set up for executed
|
||||
processes.
|
||||
|
||||
* .timer units now accept calendar specifications in other timezones
|
||||
than UTC or the local timezone.
