2019-11-25Fix panic in sniffer.Kevin Krakauer
Packets written via SOCK_RAW are guaranteed to have network headers, but not transport headers. Check first whether there are enough bytes left in the packet to contain a transport header before attempting to parse it. PiperOrigin-RevId: 282363895

2019-11-20Pass OpenTruncate to gofer in Open call when opening file with O_TRUNC.Nicolas Lacasse
Note that the Sentry still calls Truncate() on the file before calling Open. A new p9 version check was added to ensure that the p9 server can handle the the OpenTruncate flag. If not, then the flag is stripped before sending. PiperOrigin-RevId: 281609112

2019-11-15Handle in-flight TCP segments when moving to CLOSE.Mithun Iyer
As we move to CLOSE state from LAST-ACK or TIME-WAIT, ensure that we re-match all in-flight segments to any listening endpoint. Also fix LISTEN state handling of any ACK segments as per RFC793. Fixes #1153 PiperOrigin-RevId: 280703556

2019-11-14Fix panic when logging raw packets via sniffer.Kevin Krakauer
Sniffer assumed that outgoing packets have transport headers, but users can write packets via SOCK_RAW with arbitrary transport headers that netstack doesn't know about. We now explicitly check for the presence of network and transport headers before assuming they exist. PiperOrigin-RevId: 280594395

2019-11-12Do not handle TCP packets that include a non-unicast IP addressGhanan Gowripalan
This change drops TCP packets with a non-unicast IP address as the source or destination address as TCP is meant for communication between two endpoints. Test: Make sure that if the source or destination address contains a non-unicast address, no TCP packet is sent in response and the packet is dropped. PiperOrigin-RevId: 280073731
