I pushed the proposed fix for initramfs-tools to https://code.launchpad.net/~bdrung/ubuntu/+source/initramfs- tools/+git/initramfs-tools/+ref/ubuntu/2091904
Besides adding autopkgtest, the relevant code change is in https://git.launchpad.net/~bdrung/ubuntu/+source/initramfs- tools/commit/?id=0d384c77a8f9ba4e63a0746b54f03cb754339c1f: ``` diff --git a/scripts/functions b/scripts/functions index 1a0880db..96a5e0d9 100644 --- a/scripts/functions +++ b/scripts/functions @@ -290,10 +290,34 @@ _update_ip_param() fi } +_set_bootif_and_ip_param_from_ibft() +{ + local iface mac + for iface in /sys/firmware/ibft/ethernet*; do + echo "iface: $iface" + [ -e "$iface/mac" ] || continue + read -r mac < "${iface}"/mac + [ -n "$mac" ] || continue + echo "mac: $mac" + BOOTIF="$mac" + case "$(cat "$iface/ip-addr")" in + *:*) + # IPv6 address + IP=off + IP6=on + ;; + esac + done +} + configure_networking() { local netdev_desc + if [ -z "${DEVICE-}${DEVICE6-}${BOOTIF-}" ] && [ -e /sys/firmware/ibft ]; then + _set_bootif_and_ip_param_from_ibft + fi + # The order of precedence here is: # 1.

The iBFT can contain IPv4 or IPv6 addresses. local-top/iscsi calls `configure_networking`. The default behaviour of `configure_networking` is DHCPv4 on all available interfaces (if ip= and ip6= are not set). If iBFT provides IPv6 addresses and no DHCPv4 server are running, `configure_networking` will only try DHCPv4 and run into a timeout. Placing the single line "ISCSI_AUTO=true" into /etc/iscsi/iscsi.initramfs, or use the kernel boot line option "iscsi_auto" will configure the network devices based on iBFT, but the code in `local-top/iscsi` will assume that the addresses are IPv4. dracut on the other hand has the kernel boot line parameters `rd.iscsi.firmware=1` and `rd.iscsi.ibft` and `ibft` as option for the `ip` parameter. The `ibft` option is a bit under documented. https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/installation_guide/chap- anaconda-boot-options mentions `ip=ibft` and dracut.cmdline mentions it. There are multiple ways to address the timeout with IPv6 iBFT: 1) Extend `local-top/iscsi` to differentiate between IPv4 and IPv6 when "iscsi_auto" is used. This information needs to be passed to `configure_networking` to only try to bring up that device and protocol. 2) Use `ip=ibft` as indicator to use ibft as source for the network configuration. If no ip= parameter is set, local-top/iscsi should default to ip=ibft when calling configure_networking. Both solutions require passing data to configure_networking. Requiring the user to set `ip=off ip6=on` is not a good user experience and not a solution in my opinion.
