https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258874 Alexander V. Chernikov <melifaro@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |melifaro@FreeBSD.org --- Comment #6 from Alexander V. Chernikov <melifaro@FreeBSD.org> --- For the record, the previous behaviour was provided by the following code in route.c: ``` /* * MSB of net should be meaningful. 0/0 is exception. */ if (net > 0) while ((net & 0xff000000) =3D=3D 0) net <<=3D 8; ``` https://cgit.freebsd.org/src/tree/sbin/route/route.c?h=3Dstable/12#n1123 This part was removed as a classful bits cleanup here: https://cgit.freebsd.org/src/commit/sbin/route/route.c?id=3Dd28210b2c2aaf32= 00907ed30d296b0d4856dd03c I have mixed opinions on that. Using 10/8 or 240/4 is certainly convenient. However, it effectively goes again the behaviour specified in inet(3), so it may be a bit confusing for the people w/o muscular memory on remembering th= at worked. I'd rather prefer to leave it in a current state. --=20 You are receiving this mail because: You are the assignee for the bug.=
