2020-09-01Fix handling of unacceptable ACKs during close.Mithun Iyer
On receiving an ACK with unacceptable ACK number, in a closing state, TCP, needs to reply back with an ACK with correct seq and ack numbers and remain in same state. This change is as per RFC793 page 37, but with a difference that it does not apply to ESTABLISHED state, just as in Linux. Also add more tests to check for OTW sequence number and unacceptable ack numbers in these states. Fixes #3785 PiperOrigin-RevId: 329616283

2020-08-25Support SO_LINGER socket option.Nayana Bidari
When SO_LINGER option is enabled, the close will not return until all the queued messages are sent and acknowledged for the socket or linger timeout is reached. If the option is not set, close will return immediately. This option is mainly supported for connection oriented protocols such as TCP. PiperOrigin-RevId: 328350576
2020-07-27Ask for *testing.T instead of storing itJay Zhuang
Storing *testing.T on test helper structs is problematic when subtests are used, because it is possible for nested tests to call Fatal on parent test, which incorrect terminates the parent test. For example func TestOuter(t *testing.T) { dut := NewDUT(t) t.Run("first test", func(t *testing.T) { dut.FallibleCall() }) t.Run("second test", func(t *testing.T) { dut.FallibleCall() } } In the example above, assuming `FallibleCall` calls `t.Fatal` on the `t` it holds, if `dut.FallibleCall` fails in "first test", it will call `Fatal` on the parent `t`, quitting `TestOuter`. This is not a behavior we want. PiperOrigin-RevId: 323350241

2020-05-29Move TCP to CLOSED from SYN-RCVD on RST.Mithun Iyer
RST handling is broken when the TCP state transitions from SYN-SENT to SYN-RCVD in case of simultaneous open. An incoming RST should trigger cleanup of the endpoint. RFC793, section 3.9, page 70. Fixes #2814 PiperOrigin-RevId: 313828777

2020-04-23Simplify Docker test infrastructure.Adin Scannell
This change adds a layer of abstraction around the internal Docker APIs, and eliminates all direct dependencies on Dockerfiles in the infrastructure. A subsequent change will automated the generation of local images (with efficient caching). Note that this change drops the use of bazel container rules, as that experiment does not seem to be viable. PiperOrigin-RevId: 308095430
2020-04-07Test TCP sender behavior against window shrinkinggVisor bot
RFC 1122 Section 3.7: A sending TCP MUST be robust against window shrinking, which may cause the "useable window" to become negative. PiperOrigin-RevId: 305377072
