2021-06-09Avoid fanout group collisions with best effortKevin Krakauer
Running multiple instances of netstack in the same network namespace can cause collisions when enabling packet fanout for fdbased endpoints. The only bulletproof fix is to run in different network namespaces, but by using `getpid()` instead of 0 as the fanout ID starting point we can avoid collisions in the common case, particularly when testing/experimenting. Addresses #6124

2021-06-07Remove unsupported syscall event for setsockopt(*, SOL_SOCKET, SO_OOBINLINE).Nicolas Lacasse
Netstack behaves as if SO_OOBINLINE is always set, and was logging an unsupported syscall event if the app tries to disable it. We don't have a real use case for TCP urgent mechanisms (and RFC6093 says apps SHOULD NOT use it). This CL keeps the current behavior, but removes the unsupported syscall event.

2021-06-05Use the NIC packets arrived at when filteringGhanan Gowripalan
As per https://linux.die.net/man/8/iptables, ``` Parameters -i, --in-interface [!] name Name of an interface via which a packet was received (only for packets entering the INPUT, FORWARD and PREROUTING chains). ``` Before this change, iptables would use the NIC that a packet was delivered to after forwarding a packet locally (when forwarding is enabled) instead of the NIC the packet arrived at.

2021-06-04Honor data and FIN from the ACK completing handshakeMithun Iyer
If the ACK completing the handshake has FIN or data, requeue the segment for further processing by the newly established endpoint. Otherwise, the segments would have to be retransmitted by the peer to be processed by the established endpoint. Doing this, keeps the behavior in parity with Linux. This also addresses a test flake with TCPNonBlockingConnectClose where the ACK (completing the handshake) and multiple retransmitted FINACKs from the peer could be dropped by the listener, when using syncookies and the accept queue is full. The handshake could eventually get completed with a retransmitted FINACK, without actual processing of FIN. This can cause the poll with POLLRDHUP on the accepted socket to sometimes time out before the next FINACK retransmission. PiperOrigin-RevId: 377651695

2021-06-04Allow sniffer receive timeout durations less than one usecSam Balana
Fixes the erronously signaled fatal error when the sniffer receive timeout duration is less than one usec. This was caused by the converstion from float64 to int64; the integer conversion truncated the floating point to 0, which signaled the fatal error. PiperOrigin-RevId: 377600179
