10 years agonetworkd: smooth transition from ipv4ll to dhcp address
Umut Tezduyar Lindskog [Wed, 2 Apr 2014 19:31:12 +0000 (21:31 +0200)]
networkd: smooth transition from ipv4ll to dhcp address

Currently when both ipv4ll and dhcp are enabled, ipv4ll
address (if one has been claimed) is removed when dhcp
address is aquired. This is not the best thing to do
since there might be clients unaware of the removal
trying to communicate.

This patch provides a smooth transition between ipv4ll
and dhcp. If ipv4ll address was claimed [1] before dhcp,
address is marked as deprecated. Deprecated address is still
a valid address and packets can be received on it but address
cannot be selected as a source address. If dhcp lease cannot
be extended, then ipv4ll address is marked as valid again.

[1] If there is no collision, claiming IPv4LL takes between 4 to
7 seconds.

sd-rtnl: fix self-reference leaks

Like sd-bus, sd-rtnl can have self-references through queued messages. In
particular, each queued message has the following self-ref loop:
  rtnl->wqueue[i]->rtnl == rtnl

When sd_rtnl_unref() gets called, we must therefore make sure we correctly
consider each self-reference when deciding to destroy the object. For each
queued message, there _might_ be one ref. However, rtnl-messages can be
created _without_ a bus-reference, therefore we need to verify the
actually required ref-count.

Once we know exactly how many self-refs exist, and we verified none of the
queued messages has external references, we can destruct the object.
We must immediately drop our own reference, then flush all queues and
destroy the bus object. Otherwise, each sd_rtnl_message_unref() call would
recurse into the same destruction logic as they enter with the same
rtnl-refcnt.

Note: We really should verify _all_ queued messages have m->rtnl set to
      the bus they're queued on. If that's given, we can change:
        if (REFCNT_GET(rtnl->n_ref) <= refs)
      to
        if (REFCNT_GET(rtnl->n_ref) == refs)
      and thus avoid recalculating the required refs for each message we
      remove from the queue during destruction.

However, it makes sense to just create the route explicitly whether it is

other entries and saves us from knowing the state of the kernel tables.
