2020-06-05Fix error code returned due to Port exhaustion.Bhasker Hariharan
For TCP sockets gVisor incorrectly returns EAGAIN when no ephemeral ports are available to bind during a connect. Linux returns EADDRNOTAVAIL. This change fixes gVisor to return the correct code and adds a test for the same. This change also fixes a minor bug for ping sockets where connect() would fail with EINVAL unless the socket was bound first. Also added tests for testing UDP Port exhaustion and Ping socket port exhaustion. PiperOrigin-RevId: 314988525

2020-06-05Fix copylocks error about copying IPTables.Ting-Yu Wang
IPTables.connections contains a sync.RWMutex. Copying it will trigger copylocks analysis. Tested by manually enabling nogo tests. sync.RWMutex is added to IPTables for the additional race condition discovered. PiperOrigin-RevId: 314817019
2020-06-05Handle TCP segment split cases as per MSS.Mithun Iyer
- Always split segments larger than MSS. Currently, we base the segment split decision as a function of the send congestion window and MSS, which could be greater than the MSS advertised by remote. - While splitting segments, ensure the PSH flag is reset when there are segments that are queued to be sent. - With TCP_CORK, hold up segments up until MSS. Fix a bug in computing available send space before attempting to coalesce segments. Fixes #2832 PiperOrigin-RevId: 314802928

2020-06-04test/syscall: run hostnet tests in separate network namespacesAndrei Vagin
A few tests use hard coded port numbers, so we need to guruantee that these ports will not be used for somthing else.

2020-06-03Pass PacketBuffer as pointer.Ting-Yu Wang
Historically we've been passing PacketBuffer by shallow copying through out the stack. Right now, this is only correct as the caller would not use PacketBuffer after passing into the next layer in netstack. With new buffer management effort in gVisor/netstack, PacketBuffer will own a Buffer (to be added). Internally, both PacketBuffer and Buffer may have pointers and shallow copying shouldn't be used. Updates #2404. PiperOrigin-RevId: 314610879

b/36576592 calls out an edge case previously not supported by HostFS. HostFS is currently being removed, meaning gVisor supports this feature. Simply add the test to open_test. PiperOrigin-RevId: 314610226

2020-06-03Avoid TCP segment split when out of sender window.Mithun Iyer
If the entire segment cannot be accommodated in the receiver advertised window and if there are still unacknowledged pending segments, skip splitting the segment. The segment transmit would get retried by the retransmit handler. PiperOrigin-RevId: 314538523
