description |
In automatically encrypted Clevis+Tang unlock of LUKS encrypted device (dmcrypt/cryptsetup) - on top of which the ZFS Pool for / resides, dhcpcd is used in order to obtain automatically an IP address during initramfs boot.
During this phase, dhcpcd is called before interfaces have carrier causing a 29 seconds boot delay.
Boot delay is currently 45 seconds, instead of the 15 seconds that it should.
BUG Initially reported in: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2064926
Relevant Logs:
```
dhcpcd-10.0.6 starting
[...]
no interfaces have a carrier
exiting due to oneshot
dhcpcd exited
Sleeping 29 seconds before retrying getting a DHCP lease
dhcpcd-10.0.6 starting
```
A possible workaround would be to manually edit /usr/share/initramfs-tools/scripts/functions
Changing this:
`for ROUNDTTT in 30 60 90 120; do`
To this:
`for ROUNDTTT in 5 5 5 5; do`
But the proper solution would be to continuously "scan" the state of the Interface (every Second or so), and wait until the interface is UP, before deciding to call dhcpcd. |
[ Impact ]
The boot time can be longer on system that configure their network in the initrd.
[ Test Plan ]
The affected systems show "Sleeping $time seconds before retrying getting a DHCP lease" in their boot log. Once applying the fix, this message should not be found any more and "dhcpcd-10.0.6 starting" should be only logged once (at most once for IPv4 and once for IPv6 depending on the boot parameters).
There are qemu-net and qemu-net-dnsmasq autopkgtests for this area of code.
[ Where problems could occur ]
The DHCP code in the initrd are touched. So the boot can be affected. Also updating initramfs-tools will regenerate the initrd and can cause issues there (like full disks, etc).
