Add DNSMatchDomains property to Interface (split DNS)

[fhriley]

Based on the work of Stephen Larew [email protected].

This adds split DNS capability. MacOS and iOS don't fully support the separation of search domains and match domains so a best effort is made to implement to what the configuration intends.

Thanks for putting this together -- it seems to behave exactly how I want it to... the question is, will it ever flow upstream?

[nicx]

any chance that this PR will make it into the official release?

[aSilentSniper]

Please Merge this request so i dont have to build it myself

[evanphx]

Anything we can do to help get this merged? Would love to see it land.

[robertoschwald]

Still this badly needed PR is not merged. PLEASE MERGE, FOLKS!

It's a bummer... I've been waiting for this before switching our company over to use WireGuard instead of OpenVPN... without it, the usability is not that great.

I continue to renew my apple developer subscription for the express purpose of building a custom WireGuard with this PR.

Keen to see split DNS on the iOS app, but it's worth noting the preference of the maintainer for contributions to this repository is either by sending properly formatted patches using git-send-email to the WireGuard mailing list, or via a prefixed branch in the official repository.

[robertoschwald]

I already sent a patch to the ml.

[philipstewart]

Wonderful - do you have a link? I could only find this one in a brief scan of the list, but the change proposed in this PR seems to be more extensive.

[robertoschwald]

Sent it April/5/24.

Is being held until the list moderator can review it for approval.
