Subject: [PATCH] n-dhcp4: discard NAKs from other servers in SELECTING

I got a report of a scenario where multiple servers reply to a REQUEST
in SELECTING, and all servers send NAKs except the one which sent the
offer, which replies with a ACK. In that scenario, n-dhcp4 is not able
to obtain a lease because it restarts from INIT as soon as the first
NAK is received. For comparison, dhclient can get a lease because it
ignores all NAKs in SELECTING.

Arguably, the network is misconfigured there, but it would be great if
n-dhcp4 could still work in such scenario.

According to RFC 2131, ACK and NAK messages from server must contain a
server-id option. The RFC doesn't explicitly say that the client
should check the option, but I think it's a reasonable thing to do, at
least for NAKs.

This patch stores the server-id of the REQUEST in SELECTING, and
compares it with the server-id from NAKs, to discard other servers'
replies.

Subject: [PATCH 1/2] dhcp: set "src" for DHCPv4 routes

Let's set the "src" (RTA_PREFSRC) of DHCP routes.
This helps with source address selection.

This can matter if the interface also has static addresses
configured.

Systemd-networkd also does this ([1], [2]).

NetworkManager stores new network profiles in keyfile format in the
/etc/NetworkManager/system-connections/ directory.

Previously, NetworkManager stored network profiles in ifcfg format
in this directory (/etc/sysconfig/network-scripts/). However, the ifcfg
format is deprecated. By default, NetworkManager no longer creates
new profiles in this format.

Connection profiles in keyfile format have many benefits. For example,
this format is INI file-based and can easily be parsed and generated.

Each section in NetworkManager keyfiles corresponds to a NetworkManager
setting name as described in the nm-settings(5) and nm-settings-keyfile(5)
man pages. Each key-value-pair in a section is one of the properties
listed in the settings specification of the man page.

If you still use network profiles in ifcfg format, consider migrating
them to keyfile format. To migrate all profiles at once, enter:

# nmcli connection migrate

This command migrates all profiles from ifcfg format to keyfile
format and stores them in /etc/NetworkManager/system-connections/.

Alternatively, to migrate only a specific profile, enter:

# nmcli connection migrate <profile_name|UUID|D-Bus_path>

For further details, see:
* nm-settings-keyfile(5)
* nmcli(1)
