Re: [Bug 221385] [Regression] v6 mapped v4 addresses not working in 11.1

2017-10-16 Thread Lewis Donzis
Would appreciate some guidance on this. It seems like a reasonably serious regression, so I’m surprised it hasn’t already been fixed. Since all of our code binds a particular library, we were able to work around it by overriding the weak referenced socket() with our own version that creates th
