> inet_aton accepts trailing characterrs after a valid IP ( https://bugzilla.redhat.com/show_bug.cgi?id=1347549). There is a little bit of confusion between getaddrinfo() and inet_aton() here (https://bugzilla.redhat.com/show_bug.cgi?id=1347549 is about getaddrinfo()). getaddrinfo() has been fixed: https://sourceware.org/bugzilla/show_bug.cgi?id=20018 But glibc devs don't want to fix inet_aton() to keep the backward compatibility ("for historic reasons"): more info in bpo-37495 "socket.inet_aton parsing issue on some libc versions". This issue is about ssl.match_hostname() which uses internally socket.inet_aton(). ssl.match_hostname() has been fixed to implement further checks to workaround inet_aton() behavior (ignore extra string after a whitespace). I also removed inet_aton() from the title of this issue to reduce confusion ;-)
