2020-05-01Support for connection tracking of TCP packets.Nayana Bidari
Connection tracking is used to track packets in prerouting and output hooks of iptables. The NAT rules modify the tuples in connections. The connection tracking code modifies the packets by looking at the modified tuples.

2020-05-01Regenerate SLAAC address on conflicts with the NICGhanan Gowripalan
If the NIC already has a generated SLAAC address, regenerate a new SLAAC address until one is generated that does not conflict with the NIC's existing addresses, up to a maximum of 10 attempts. This applies to both stable and temporary SLAAC addresses. Test: stack_test.TestMixedSLAACAddrConflictRegen PiperOrigin-RevId: 309495628

2020-05-01Port netstack, hostinet, and netlink sockets to VFS2.Dean Deng
All three follow the same pattern: 1. Refactor VFS1 sockets into socketOpsCommon, so that most of the methods can be shared with VFS2. 2. Create a FileDescriptionImpl with the corresponding socket operations, rewriting the few that cannot be shared with VFS1. 3. Set up a VFS2 socket provider that creates a socket by setting up a dentry in the global Kernel.socketMount and connecting it with a new FileDescription. This mostly completes the work for porting sockets to VFS2, and many syscall tests can be enabled as a result. There are several networking-related syscall tests that are still not passing: 1. net gofer tests 2. socketpair gofer tests 2. sendfile tests (splice is not implemented in VFS2 yet) Updates #1478, #1484, #1485 PiperOrigin-RevId: 309457331

2020-04-30Make tcp_close_wait_ack_test more accurateZeling Feng
Previously the test used an out-dated window size which is advertised during the handshake to generate testing packets, but the window size has changed since the handshake; currently it is using the most recent one which is advertised in DUT's ACK to our FIN packet to generate the testing outside-the-window packets.
