[Bionic-only] URL's under non-compliant A records do not resolve

[alexytomi]

Because Bionic, getaddrinfo() fails to resolve A records like __test.something.com because it technically doesn't comply with the DNS standards, the code responsible for this is found here https://android.googlesource.com/platform/bionic.git/+/refs/tags/android-16.0.0_r4/libc/dns/resolv/res_comp.c#151

Here is a real-world example, the record is "malformed" into this because of Cloudflare proxying.

Theory as to how this happens is as follows

• Make a proxied A record
• Add SRV record
• Cloudflare does its magic

This seems to be exactly what the OGCraft server owner had done as well as what this thread details

This has been discussed to be not planned in private development channels due to literally being non-compliant but documenting it is nice

Note: This does work under glibc and windows. Only android does this.

Changed our minds, this is planned to be fixed
