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
new boolean setting Assign=. If enabled an address from the prefix is
automatically assigned to the interface.
- * 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 interfaces.
+ * 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
IPv4AcceptLocal=. If enabled the interface accepts packets with local
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.
