Summary: 802.1q tagged vlan 4095 sometimes crashes vde-switch
Initial Comment:
Hello,
When the vde-switch receives a packet with 802.1q tagged vlan 4095 (yes, I
know, these packets shouldn't be on the network..), it looks up vlant[4095].
This sometimes triggers a segfault.
I would suggest you add a
if (vlan >= NUMOFVLAN)
return; /* discard unwanted packets */
between these lines
vlan=((packet->data[0] << 8) + packet->data[1]) & 0xfff;
if (! BA_CHECK(vlant[vlan].table,port))
return; /*discard unwanted packets*/
Regards,
Bas van Sisseren
