Add support for PACKET_RX_RING w/ TPACKET_V2
hbhasker opened this issue · comments
Description
In issue #6664 (comment) it was discovered that the latest versions of libpcap have removed all non-mmapped packet capture support as of this commit the-tcpdump-group/libpcap@457027a.
Which means latest versions of tcpdump do not work in gVisor. We will need to add support for PACKET_RX_RING w/ TPACKET_v2 at least to be able to support tcpdump. We can punt on PACKET_TX_RING for now as its not required for tcpdump. TPACKET_v3 is more complicated and probably not required at the moment.
