Patch contains a coccinelle script, but it only works in some cases. Many
parts were converted by hand.
Note: I did not fix errors in return value handing. This will be done separate
to keep the patch comprehensible. No functional change is intended in this
patch.
Users might want to use that to unset a previous setting. The docs seem OK as
they are: we don't need to explictly mention the empty value, since it is
almost always allowed.
Those fields are both uint32_t, so we should use the same type when parsing.
Having a different type didn't change the result, but let's be consistent.
In order to allow other parts of systemd-networkd to use sets/hashmaps
of Address objects, the address_hash_ops structure needs to be made
available to them.
PrefixRoute= was added by e63be0847c,
but unfortunately, the meaning of PrefixRoute= is inverted; when true
IFA_F_NOPREFIXROUTE flag is added. This introduces AddPrefixRoute=
setting.
Don't reset the conflict counter when trying a new pseudo random
address, so that after trying 10 addresses the londer timeout is used in
accordance with the RFC
Fixes#14299.
*We* control the sysctl setting. If the user configured IPv6, then we apply the
settings, and just make sure that at some point during the configuration the
sysctl is disabled (i.e. ipv6 enabled) if we have IPv6 configured.
Replaces #13283.
Without this change, the address with PreferredLifetime=0 cannot be ready,
and thus, no consequent setting up process does not start.
The bug was introduced by 6aa5773.
Follow-up for b7ed5384ab.
Fixes#13341.
If e.g., an [Address] section has an invalid setting, then
previously assigned settings in the section is freed, and
only later settings are stored. That may cause partially broken
section stored in Network object.
This makes if an invalid setting is found, then set 'invalid' flag
instead of freeing it. And invalid sections are dropped later by
network_verify().
- Do not allocate NetworkConfigSection when filename == NULL
- set .network element before calling hashmap_put()
- Always free NetworkConfigSection in each object.
In case networkd is restarted this prevents a removal of an already existing IP
address that would be configured using networkd. With the proposed changes the
IP address will be kept on the interface without removing. This happens only on
physical hosts or VMs since networkd handles interface configuration slightly
different in containers.
