2021-06-22Remove timeoutsTamir Duberstein
These aren't useful and create opportunities for flakes. PiperOrigin-RevId: 380889223
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
2021-05-20Add protocol state to TCPINFOMithun Iyer
Add missing protocol state to TCPINFO struct and update packetimpact. This re-arranges the TCP state definitions to align with Linux. Fixes #478 PiperOrigin-RevId: 374996751
2021-03-15Packetimpact test for ACK to OTW Seq segments behavior in CLOSINGZeling Feng
TCP, in CLOSING state, MUST send an ACK with next expected SEQ number after receiving any segment with OTW SEQ number and remain in the same state. While I am here, I also changed shutdown to behave the same as other calls in posix_server. PiperOrigin-RevId: 362976955
2021-03-06[op] Replace syscall package usage with golang.org/x/sys/unix in test/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in some places because the following don't seem to have an equivalent in unix package: - syscall.SysProcIDMap - syscall.Credential Updates #214 PiperOrigin-RevId: 361332034
2021-03-05Gather uname information from DUTZeling Feng
Some OSs behave slightly differently, but still within the RFC. It can be useful to have access to uname information from the testbench. PiperOrigin-RevId: 361193766
2021-02-25Move SetNonblocking into posix_serverZeling Feng
- open flags can be different on different OSs, by putting SetNonblocking into the posix_server rather than the testbench, we can always get the right value for O_NONBLOCK - merged the tcp_queue_{send,receive}_in_syn_sent into a single file PiperOrigin-RevId: 359620630
2021-02-17Deflake tcp_network_unreachable testZeling Feng
Previously, we make two connect attempts. If the first attempt is still on going when the second attempt is made, the test will fail. This change deflakes the situation by not making the second attempt, instead, we poll for the first attempt's completion and read the errno from SO_ERROR. PiperOrigin-RevId: 358104769
2021-01-28Make tcp_noaccept_close_rst more robustZeling Feng
There used to be a race condition where we may call Close before the connection is established. Adding poll support so that we can eliminate this kind of race. Startblock: has LGTM from iyerm and then add reviewer tamird PiperOrigin-RevId: 354369130
2021-01-28Respect SO_BINDTODEVICE in unconnected UDP writesMarina Ciocea
Previously, sending on an unconnected UDP socket would ignore the SO_BINDTODEVICE option. Send on the configured interface when an UDP socket is bound to an interface through setsockop SO_BINDTODEVICE. Add packetimpact tests exercising UDP reads and writes with every combination of bound/unbound, broadcast/multicast/unicast destination, and bound/not-bound to device. PiperOrigin-RevId: 354299670
2020-11-23[1/3] Support isolated containers for parallel packetimpact testsZeling Feng
Summary of the approach: the test runner will set up a few DUTs according to a flag and pass all the test networks to the testbench. The testbench will only reside in a single container. The testbench will put all the test networks into a buffered channel which served as a semaphore and now the user can freely use t.Parallel() in (sub)tests and the true parallelism will be determined by how many DUTs are configured. Creating DUTs on demand is not supported yet, the test author should determine the number of DUTs to be used statically. Specifically in this change: - Don't export any global variables about the test network in testbench. - Sniffer only binds on the local interface because it will be possible to have multiple interfaces to multiple DUTs in a single testbench container. - Migrate existing tests to stop using global variables.

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
