https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256393 Bug ID: 256393 Summary: Issue with recreation of ppp/tun interfaces Product: Base System Version: 13.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: nwhitehorn@FreeBSD.org I am running a machine acting as a ppp server using userland ppp(8) and run= ning 13-STABLE (this issue does not occur on 13.0-RELEASE and earlier). When a client establishes a connection, everything is fine and a connection is established without issue. When that connection ends and the client attempt= s to re-establish the connection, however, IPCP fails and just continues in a lo= op, never setting the IP address on the local tun(4) interface. If I try to set= it by hand, I get this: root@conference:/home/nwhitehorn # ifconfig tun0 tun0: flags=3D8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500 options=3D80000<LINKSTATE> inet6 fe80::f816:3eff:fe26:d92a%tun0 prefixlen 64 scopeid 0x3 groups: tun nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> Opened by PID 1359 root@conference:/home/nwhitehorn # ifconfig tun0 192.168.42.1 192.168.42.2 ifconfig: ioctl (SIOCAIFADDR): File exists This seems like a regression in tun(4), but I haven't had a chance to really debug it. --=20 You are receiving this mail because: You are the assignee for the bug.=
