-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, Recently, OpenBSD have moved from RC4 to ChaCha20 for their arc4random(3) family of functions and they have later removed a few interfaces for good reasons. On FreeBSD, we aim to maintain ABI stability so we can not simply remove the interface; we can not remove it from -HEAD because they are established by previous -STABLE branches, or we would have to bump major number of shared libraries. After thinking about some other alternatives, I have created two dummy (well, they also log the event) compatibility shims for these two interfaces that gets removed from OpenBSD. Is this a reasonable approach of handling changes like this? Cheers, - -- Xin LI <delphij@delphij.net> https://www.delphij.net/ FreeBSD - The Power to Serve!
