A future commit will add support for unicode collation protocol that
allows case folding and comparing strings with locale awareness. But it
only operates on whole strings, so fnmatch cannot use those without a
heavy cost. Instead we just case fold the patterns instead (the IDs we
try to match are already lower case).
New directive `DynamicUserNFTSet=` provides a method for integrating
configuration of dynamic users into firewall rules with NFT sets.
Example:
```
table inet filter {
set u {
typeof meta skuid
}
chain service_output {
meta skuid != @u drop
accept
}
}
```
```
/etc/systemd/system/dunft.service
[Service]
DynamicUser=yes
DynamicUserNFTSet=inet:filter:u
ExecStart=/bin/sleep 1000
[Install]
WantedBy=multi-user.target
```
```
$ sudo nft list set inet filter u
table inet filter {
set u {
typeof meta skuid
elements = { 64864 }
}
}
$ ps -n --format user,group,pid,command -p `pgrep sleep`
USER GROUP PID COMMAND
64864 64864 55158 /bin/sleep 1000
```
New directives `NFTSet=`, `IPv4NFTSet=` and `IPv6NFTSet=` provide a method for
integrating configuration of dynamic networks into firewall rules with NFT
sets.
/etc/systemd/network/eth.network
```
[DHCPv4]
...
NFTSet=netdev:filter:eth_ipv4_address
```
```
table netdev filter {
set eth_ipv4_address {
type ipv4_addr
flags interval
}
chain eth_ingress {
type filter hook ingress device "eth0" priority filter; policy drop;
ip saddr != @eth_ipv4_address drop
accept
}
}
```
```
sudo nft list set netdev filter eth_ipv4_address
table netdev filter {
set eth_ipv4_address {
type ipv4_addr
flags interval
elements = { 10.0.0.0/24 }
}
}
```
New directive `NetLabel=` provides a method for integrating dynamic network
configuration into Linux NetLabel subsystem rules, used by Linux security
modules (LSMs) for network access control. The option expects a whitespace
separated list of NetLabel labels. The labels must conform to lexical
restrictions of LSM labels. When an interface is configured with IP addresses,
the addresses and subnetwork masks will be appended to the NetLabel Fallback
Peer Labeling rules. They will be removed when the interface is
deconfigured. Failures to manage the labels will be ignored.
Example:
```
[DHCP]
NetLabel=system_u:object_r:localnet_peer_t:s0
```
With the above rules for interface `eth0`, when the interface is configured with
an IPv4 address of 10.0.0.0/8, `systemd-networkd` performs the equivalent of
`netlabelctl` operation
```
$ sudo netlabelctl unlbl add interface eth0 address:10.0.0.0/8 label:system_u:object_r:localnet_peer_t:s0
```
Result:
```
$ sudo netlabelctl -p unlbl list
...
interface: eth0
address: 10.0.0.0/8
label: "system_u:object_r:localnet_peer_t:s0"
...
```
/etc/os-release existence is only enforced in --boot mode,
therefore the term "starting" (which also applies to chroot-like mode)
is substituted with "booting" in this context.
The recommendation to use machinectl login/shell instead of
trying to combine two distinct container instances seemed a
litte bit out of context and is now combined via "rather".
The existing sd_hwdb_new function always initializes the hwdb from the
first successful hwdb.bin it finds from hwdb_bin_paths. This means there
is currently no way to initialize a hwdb from an explicit path, which
would be useful for systemd-hwdb query.
Add sd_hwdb_new_from_path to allow a sd_hwdb to be initialized from a
custom path outside of hwdb_bin_paths.
All wiki pages that contain a deprecation banner
pointing to systemd.io or manpages are updated to
point to their replacements directly.
Helpful command for identification of available links:
git grep freedesktop.org/wiki | \
sed "s#.*\(https://www.freedesktop.org/wiki[^ $<'\\\")]*\)\(.*\)#\\1#" | \
sort | uniq
* Avoid traling slash as most links are defined without.
* Always use https:// protocol and www. subdomain
Allows for easier tree-wide linkvalidation
for our migration to systemd.io.
The interface, output, and exit status convention are all taken directly from
rpmdev-vercmp and dpkg --compare-versions. The implementation is different
though. See test-string-util for a list of known cases where we compare
strings incompatibly.
The idea is that this string comparison function will be declared as "the"
method to use for boot entry ordering in the specification and similar
uses. Thus it's nice to allow users to compare strings.
The methods published by the example have a reply in the signature, but
the code was not sending any, so the client gets stuck waiting for a
response that doesn't arrive. Echo back the input string.
Update the object path to follow what would be the canonical format.
Request a service name on the bus, so that the code can be dropped in a
service and it can be dbus-activatable. It also makes it easier to see
on busctl list.
In the documentation, using the term "managed" for both the RA flag and
the DHCPv6 mode is confusing because the mode is referred to as
"solicit" both in the official DHCPv6 documentation (see RFC 8415) and
in the WithoutRA option.
Furthermore, calling the other RA flag "other information" or "other
address configuration" is confusing because its official name is simply
"other configuration" (see RFC 4861 and RFC 5175) and it isn't used to
assign IP addresses.
Rewrite the documentation for DHCPv6Client and WithoutRA to make it
clear that getting the "managed" RA flag triggers the same kind of DHCP
request as WithoutRA=solicit, whereas getting the "other configuration"
RA flag triggers the same kind of DHCP request as
WithoutRA=information-request.
