Upgrade to dev-libs/libdnet-1.14 is blocked due to lack of ipv6 flag, which is needed for fragroute: # emerge -pv dev-libs/libdnet These are the packages that would be merged, in order: Calculating dependencies... done!

Created attachment 662275 [details] new libdnet-1.14 ebuild The attached ebuild restores the ipv6 flag, and both libdnet-1.14 and net-analyzer/fragroute-1.2.6-r3 build correctly with it in place. I didn't test fragroute to any extend, but since the creator is the provider of this libdnet patch I assume it works OK.
Comment on attachment 662275 [details] new libdnet-1.14 ebuild Not going to do that. Upstream for libdnet needs to implement these changes officially to expose the new API features. As you can see from the See alsos, this process was set in motion some time ago, and the new API features have been implemented but not yet released. If you want to actually help, then you will need to ask libdnet developers to release a new version with those changes.

For context, libdnet development was in limbo for years, so the previous addition of the "ndisc/ipv6" patch from the fragroute authors seemed fine. With recent changes in the life of libdnet, however, adding patches in that way is not ideal. For instance, the "ndisc" addition to the previously added IPv6 support should be accompanied with a libtool version/SONAME change[0], as the users of libdnet should be able to find out whether it supports the new feature.

I suppose this means that fragroute is on its way out.

Since the ndisc feature in libdnet is used solely by fragroute, I decided that as long as the in-tree usage is consistent, there should be no need to wait for libdnet upstream to release a new version with the API changes.
