https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242637 Bug ID: 242637 Summary: [patch] emulators/virtualbox-ose: fix bridging when the ng_ether node name does not match the interface name Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: vbox@FreeBSD.org Reporter: landonf@FreeBSD.org Assignee: vbox@FreeBSD.org Flags: maintainer-feedback?(vbox@FreeBSD.org) Created attachment 209951 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D209951&action= =3Dedit Patch for current (5.2.34) emulators/virtualbox-ose This patch fixes bridging in cases where the interface's ng_ether netgraph = node name does not match its interface name. This is commonly seen with VLANs configured in rc.conf; for example: ifconfig_igb0=3D"up" vlans_igb0=3D"12" This will create an 'igb0.12' VLAN interface, but because '.' is a reserved character in netgraph node names, the corresponding netgraph node will be n= amed 'igb0_12': Name: igb0_12 Type: ether ID: 00000007 Num hooks: 0 Currently, VBoxNetFlt assumes a 1:1 correspondence between interface name a= nd ng_ether node name; when attempting to bridge to igb0.12, the node named "igb0.12" is not found, and VBoxNetFlt's netgraph initialization silently fails. Rather than assume the node name, this patch enumerates all ng_ether nodes, using the NGM_ETHER_GET_IFNAME control message to identify the ng_ether node corresponding to the target interface. I've attached patches for the current emulators/virtualbox-ose port, as wel= l as a patch relative to the 6.1 patch posted on 2019-12-13 (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234878). --=20 You are receiving this mail because: You are the assignee for the bug.=
