In init.d/iscsi the portal address is collected thusly:
echo "$(cat "$connectiondev/persistent_address"):$(cat
"$connectiondev/persistent_port"),$(cat "/sys/$sessiondev/tpgt")"
>iscsi_portal
resulting in an iscsi_portal file looking like
2606:a000:a449:5900::4:3260,1
In finish.d/iscsi_settings, this string is then picked apart:
group="${portal##*,}"
portal="${portal%,*}"
ip="${portal%%:*}"
port="${portal#*:}"
These variables are then used to populate iscsi.initramfs, which ends up
looking like this:
ISCSI_TARGET_NAME="iqn.2016-11.net.nivex:storage.istest"
ISCSI_TARGET_IP="2606"
ISCSI_TARGET_PORT="a000:a449:5900::4:3260"
ISCSI_TARGET_GROUP="1"
ISCSI_USERNAME="istest"
ISCSI_PASSWORD="123456789012"
I think the easiest fix would be to switch the greed of the matching, as in:
ip="${portal%:*}"
port="${portal##*:}"
though I worry about naively splitting on colon when dealing with IPv6
addresses like this.
