Hello,
I recently had to revisit and slightly improve the patches I sent to the
list in January. They are attached in this mail, and also available at
<http://gitweb.fperrin.net/?p=iftop.git;a=shortlog;h=refs/heads/ip6reverse>.
Paul, can you apply them if they DTRT ?
The first patch makes iftop compile on FreeBSD.
The second and the third make reverse ip6 resolution available to
methods beyond getnameinfo(3).
The methods that correctly resolve reverse ip6 addresses are:
- getnameinfo;
- gethostbyaddr_r;
- gethostbyaddr;
- gethostbyaddr with fork.
This leaves out the ares and libresolv methods, I suppose that can be
fixed quickly.
In patch n°3, this is done by saving the addresses in a structure that
remembers the AF, which is given by the caller to resolve(). I believe
this in the correct thing to do.
In patch n°2, this is done by importing the getnameinfo's AF guessing to
these methods. This is less intrusive.
