[ruby-core:101992] [Ruby master Feature#17524] resolv: add some more characters in IPv6 link local zone id

[nov]

Issue #17524 has been reported by no6v (Nobuhiro IMAI).

----------------------------------------
Feature #17524: resolv: add some more characters in IPv6 link local zone id
https://bugs.ruby-lang.org/issues/17524

* Author: no6v (Nobuhiro IMAI)
* Status: Open
* Priority: Normal
----------------------------------------
According to [RFC6874](https://tools.ietf.org/html/rfc6874#section-2), IPv6 link local zone id is:

```
   ZoneID = 1*( unreserved / pct-encoded )
```

where `unreserved` in [RFC3986](https://tools.ietf.org/html/rfc3986#section-2.3) is as follow.

```
   unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"
```

Actually, `docker` can create such an interface.

```sh
$ docker network create --ipv6 --subnet fe80::/64 --opt com.docker.network.bridge.name=ruby_3.0.0-1 ruby
$ ruby -rsocket -e 'p Socket.ip_address_list.last'
#<Addrinfo: fe80::1%ruby_3.0.0-1>
```

This makes `TestResolvAddr#test_valid_socket_ip_address_list` failure.
Supporting a `pct-encoded` may be overwork, but adding the all of `unreserved` to

* `Resolv::IPv6::Regex_8HexLinkLocal` and
* `Resolv::IPv6::Regex_CompressedHexLinkLocal`

sounds reasonable for me. What do you think?

[ruby-core:101995] [Ruby master Feature#17524] resolv: add some more characters in IPv6 link local zone id

[merch-redmine]

Issue #17524 has been updated by jeremyevans0 (Jeremy Evans).

Assignee set to akr (Akira Tanaka)
Status changed from Open to Assigned

This seems reasonable to me.  I chose a more conservative approach in the initial implementation, but we've already had to expand it once for s390, and if adding the rest of the unreserved characters fixes docker, we should do that.

I've submitted a pull request upstream for this: https://github.com/ruby/resolv/pull/2

[jaruga]

Issue #17524 has been updated by jaruga (Jun Aruga).


I just faced this issue where `cni-podman0` including `-` is used as string matching with `Resolv::IPv6::Regex_CompressedHexLinkLocal`.

```
$ ruby -rsocket -e 'p Socket.ip_address_list[8]'
#<Addrinfo: fe80::9856:24ff:fe1b:f759%cni-podman0>
```

[gotoken (Kentaro Goto)]

Issue #17524 has been updated by gotoken (Kentaro Goto).


With ruby 3.1.0 on my LXC box, this is the only problem reported as a failure with `make test-all`.
It would be helpful if you could merge https://github.com/ruby/resolv/pull/2.
