Trying dual-stack on some embedded platform, I noticed that quite frequently (20%) libCurl starts from IPv4 regardless the Happy Eyeballs timeout value. After debugging this issue, I noticed that this happens if c-ares resolver response for IPv6 family comes before IPv4 (which was randomly happening in my tests). In such cases, because libCurl puts the last resolver response on top of the address list, when IPv4 resolver response comes after IPv6 one - the IPv4 family starts the connection phase instead of IPv6 family. The solution for this issue is to always put IPv6 addresses on top of the address list, regardless the order of resolver responses. Bug: https://curl.se/mail/lib-2021-06/0003.html Closes #7188 |
