Hi, I just stumbled over this today:
> root@fc60 [prod] ~ # ping6 -s 1445 rzob-router.gocept.net > PING rzob-router.gocept.net (2a02:248:101:63::1): 1445 data bytes > 1240 bytes from 2a02:238:1:f030::2: Packet too big, mtu=-737869824 Looking at the code this seems to be a formatting issue where ping is using a %d instead of %u for an unsigned 32 bit integer. I guess nobody really does send this big MTUs so it doesn’t normally matter, but my ISP is doing funny things today … le sigh.
