All,
Just realized that lcr module does not support IPv6 yet. Is there
already any work going on here? Otherwise we'd take this task over.

i don't know of such work. if you decide to do it, try to not cause any
performance hit for current ipv4 usage.

andreas,
based on the patch i got impression that it uses current ip_addr column
of lcr_gw table to store also ipv6 address? if so, then also the schema
file would need to be changed.

Exactly. Sorry, forgot that part. Since the patch supports optional
surrounding square brackets, the max. length of an IPv6 address is 47.
So it's either 8*4+7+2 for normal IPv6, like
"[0000:0000:0000:0000:0000:0000:0000:0000]", or (6*4+5)+1+(4*3+3)+2 for
tunneling, like "[0000:0000:0000:0000:0000:0000:192.168.100.100]".
We could argue whether to not support square brackets and just allow
plain IP format, I've no strong opinions on that. We just wanted to make
it as flexible as possible.
Should I adapt the patch to reflect the schema change as well, or could
you maybe change it manually in lib/srdb1/schema/lcr_gw.xml?

i cannot comment on storing ipv6 address, because i don't know anything
about them. one possibility is to add a new column ipv6_addr to lcr_gw
table and take the address from the one which is not empty (if any).

Well, the question was not where to store the IPv6 address, rather than
in which format. As it is now, it'll allow it both with and without
surrounding square brackets. That's where I have no strong opinions.
However, with the current implementation, it'll re-use the ip_addr
column, because in my opinion there is no point in adding another one.
If I want to add an IPv6 gateway, I put the IPv6 address there,
otherwise the IPv4 address. If a gateway supports both, I can insert the
gateway twice and control via lcr_rule_target the priority and weight in
order to have a fall-back or whatever. I'd highly favor keeping that
approach.

ok, then push also change to lcr_gw schema and include an upgrade script
in wiki (or where ever that are nowadays stored).

I agree. IPv6 has no brackets, that's just a notation for using in URI's.
