From 3c31ef05ba732e3ab5d23761c5f84768ca8de68e Mon Sep 17 00:00:00 2001

Subject: [PATCH] sd-netlink: introduce sd_netlink_message_read_strv()
The combination of sd_netlink_message_enter_container() and
sd_netlink_message_read_string() only reads the last element if the attribute is
duplicated, such a situation easily happens for IFLA_ALT_IFNAME.
The function introduced here reads all matched attributes.
(cherry picked from commit 8f3c1859669230c2c8458675f41de13e369b47e7)

Subject: [PATCH] netlink: do not fail when new interface name is already used
as an alternative name
When renaming a network interface, the new name may be used as an
alternative name. In that case, let's swap the current name and the
alternative name. That is, first drop the new name from the list of
alternative names, then rename the interface, finally set the old name
as an alternative name.
(cherry picked from commit 434a34838034347f45fb9a47df55b1a36e5addfd)

Subject: [PATCH] sd-hwdb: allow empty properties
So far we didn't allow empty properties, but it makes sense to do so, for
example to distinguish empty data from lack of data. It also makes it easy to
override properties (back to the empty) value for specific cases.
