Yu Watanabe 50550722e3 network: fix NDisc handling for the case when multiple routers exist 
69203fba70 does not consider the case that
multiple routers exist, and causes #16719.

Fixes #16719.

Yu Watanabe ea121d8f25 network: update address infomation even if link is in failed or linger state 
As the link may be reconfigured later. If we do not update the address
information, then its setup state or operstate may not be updated
correctly.

Yu Watanabe e55265184b network: do not assume static addresses are configured 
link_request_set_routes() is also called when a dynamic address is
configured. At that time, static addresses may not be configured yet.

Fixes #16546.

Yu Watanabe 1633c45731 network: dhcp6: drop addresses and delegated prefixes on client stop 
Previously, we did not drop addresses and delegated prefixes when
DHCP6 client is stopped.

Fixes #15455.
Fixes #13564.

Yu Watanabe 69203fba70 network: ndisc: remove old addresses and routes after at least one SLAAC address becomes ready 
Otherwise, the old addresses will exist in deperecated state.

Yu Watanabe 6e537f62d7 network: dhcp4: release old lease after the new address become ready 
Previously, on DHCPv4 address renewal, the old address may be removed
while the new address is not ready yet.

This also simplifies the logic of removing address and routes.

Zbigniew Jędrzejewski-Szmek de7fef4b6e tree-wide: use set_ensure_put() 
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.

Zbigniew Jędrzejewski-Szmek 10b20e5a93 network: allow empty assignment to PreferredLifetime= 
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.
 2020-05-25 14:52:04 +02:00
Zbigniew Jędrzejewski-Szmek d273579667 network: use consistent type when parsing lifetimes 
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.

Susant Sahani 5ead535224 network: Introduce method to generate EUI-64 addresses 2020-03-01 00:16:51 +09:00
Yu Watanabe 07336a0672 network: assume Scope=host when Address= is loopback address 
Fixes #14903.
 2020-02-28 09:53:36 +01:00
Kevin P. Fleming 8a98f11ed0 network: Make address_hash_ops available outside of networkd-address.c 
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.

Yu Watanabe 98b0299479 network: append INTERFACE= attributes for logs corresponds to a netif 2020-01-07 22:20:43 +09:00
Yu Watanabe de697db05b network: introduce AddPrefixRoute= and deprecate PrefixRoute= 
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.

AJ Bagwell e92b60b20f ipv4ll: do not reset conflict counter on restart 
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.

Susant Sahani 051e77cac1 network: introduce DAD for static address 
Closes #2527.

Zbigniew Jędrzejewski-Szmek 24be91817f networkd: split out helper function for address extraction 2019-09-17 19:09:57 +02:00
Zbigniew Jędrzejewski-Szmek 57ad760746 network: drop all checks of ipv6_disabled sysctl 
*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.

Yu Watanabe ce158189a8 network: do not check deprecated flag in address_is_ready() 
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.

Yu Watanabe bafa964144 network: read link specific sysctl value 
This introduce link_sysctl_ipv6_enabled() and replaces
manager_sysctl_ipv6_enabled() with it.

Yu Watanabe 54a1a535bd network: ignore requested ipv6 addresses when ipv6 is disabled by sysctl 2019-06-12 11:02:33 +09:00

Yu Watanabe 67a4683364 network: use IN_ADDR_NULL and ETHER_ADDR_NULL 
The change in manager_rtnl_process_address() may not be necessary,
but for safety, let's initialize the value.

Lennart Poettering 0a9707187b util: split out memcmp()/memset() related calls into memory-util.[ch] 
Just some source rearranging.

Yu Watanabe fcbf4cb727 network: drop sections contain invalid settings in network_verify() 
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().

Yu Watanabe 9560e5b323 network: make all xxx_new_static() static 
These functions are called from only config parsers, and the parsers are
in the same files. So, let's make them static.

Yu Watanabe 4aa4c4b0f4 network: avoid address section freed 
Otherwise, if HomeAddress= or friends are specified at the first line of
a section, then its assignment will be ignored.

Yu Watanabe 959f65d32e network: make bond master follow operstates of slaves 
If one of bond slaves is in off, no-carrier, or dormant, then
bond master is set to degraded.

Yu Watanabe d40b01e44b network: in_addr_is_null() may return negative errno 
So, do not silently cast the returned value to boolean.
Exception is the case that family is trivially AF_INET or AF_INET6.
