renew and 2 rebind Status in systemd: Fix Released Status in systemd package in Ubuntu: In Progress Status in systemd source package in Bionic: Fix Committed Status in systemd source package in Focal: Fix Committed Status in systemd source package in Groovy: Fix Committed Status in systemd source package in Hirsute: In Progress Bug description: [impact] networkd dhcpv4 client never attempts more than 2 renew and 2 rebind [test case] configure an interface to use dhcpv4; acquire a dhcpv4 address, then stop the dhcpv4 server, and wait for the networkd client to perform its renewals and rebinds before expiring the lease using a 20 minute lease time as an example (all times are approximate due to RFC-mandated random 'fuzz' time of -1 to +1 sec): the current behavior would be to sent renew requests at: 10:00 13:45 and then rebind requests at: 17:30 18:45 then the lease would expire at 20:00 the correct/new behavior should be renew requests at: 10:00 13:45 15:37 16:37 and then rebind requests at: 17:30 18:45 19:45 and then lease expiration at 20:00. longer lease times would increase the number of retransmissions. [regression potential] any regression would likely result in problems receiving and/or maintaining a dhcpv4 address [scope] this is needed in b/f/g/h. this was fixed upstream in: https://github.com/systemd/systemd/pull/17908 that was just added, so this is not fixed in any ubuntu release yet. technically, this is needed in x as well, however I don't plan to backport to x since 1) it reaches ESM soon and 2) the default network management tool in x is ifupdown, not systemd-networkd.
