Hi Ben,
The cleanup of IPv6 address parsing is greatly appreciated. I haven't
yet reviewed the meat of this patchset, but I figured I'd weigh in on
the commit message on this patch.
I wrote the newer parsing code when extending load balancers to work for
IPv6. The issues I ran into were:
* Load balancer addresses in OVN have optional ports.
* Other user commands in OVN that use IPv6 addresses do not require
square brackets around the IPv6 address (e.g. `ovn-nbctl lsp-set-addresses`)
Interestingly, there had not yet been any user commands that would
accept an IPv6 address with an optional port. The choices were either to
require square brackets around all IPv6 addresses used in load
balancers, or allow bracket-less addresses when no port was specified.
To me, it would seem weird as a user if I had to put square brackets
around IPv6 addresses for some commands but not for others. Also in
other programs I've used, I am not used to including brackets on an IPv6
address when there is no port present. I elected to go with the method
that allowed for brackets to be required only when a port is present.
Unfortunately, no such function existed that would allow for this.
inet_parse_active() was close, but it required square brackets around
IPv6 addresses. So that's why I wrote the new function.
To address your ambiguity concern, "::1:2:3:4:80" is an IPv6 address
with no port. With no square brackets present, that's the only sensible
way to interpret it.
I'll have a deeper look at the entire patchset and give more feedback on
it later.
Mark!
