2021-05-27Support SO_BINDTODEVICE in ICMP socketsSam Balana
Adds support for the SO_BINDTODEVICE socket option in ICMP sockets with an accompanying packetimpact test to exercise use of this socket option. Adds a unit test to exercise the NIC selection logic introduced by this change. The remaining unit tests for ICMP sockets need to be added in a subsequent CL. See https://gvisor.dev/issues/5623 for the list of remaining unit tests. Adds a "timeout" field to PacketimpactTestInfo, necessary due to the long runtime of the newly added packetimpact test. Fixes #5678 Fixes #4896 Updates #5623 Updates #5681 Updates #5763 Updates #5956 Updates #5966 Updates #5967 PiperOrigin-RevId: 376271581
2021-05-05Fix a race in reading last seen ICMP error during handshakeMithun Iyer
On receiving an ICMP error during handshake, the error is propagated by reading `endpoint.lastError`. This can race with the socket layer invoking getsockopt() with SO_ERROR where the same value is read and cleared, causing the handshake to bail out with a non-error state. Fix the race by checking for lastError state and failing the handshake with ErrConnectionAborted if the lastError was read and cleared by say SO_ERROR. The race mentioned in the bug, is caught only with the newly added tcp_test unit test, where we have control over stopping/resuming protocol loop. Adding a packetimpact test as well for sanity testing of ICMP error handling during handshake. Fixes #5922 PiperOrigin-RevId: 372135662
2021-04-05Fix listen backlog handling to be in parity with LinuxMithun Iyer
- Change the accept queue full condition for a listening endpoint to only honor completed (and delivered) connections. - Use syncookies if the number of incomplete connections is beyond listen backlog. This also cleans up the SynThreshold option code as that is no longer used with this change. - Added a new stack option to unconditionally generate syncookies. Similar to sysctl -w net.ipv4.tcp_syncookies=2 on Linux. - Enable keeping of incomplete connections beyond listen backlog. - Drop incoming SYNs only if the accept queue is filled up. - Drop incoming ACKs that complete handshakes when accept queue is full - Enable the stack to accept one more connection than programmed by listen backlog. - Handle backlog argument being zero, negative for listen, as Linux. - Add syscall and packetimpact tests to reflect the changes above. - Remove TCPConnectBacklog test which is polling for completed connections on the client side which is not reflective of whether the accept queue is filled up by the test. The modified syscall test in this CL addresses testing of connecting sockets. Fixes #3153 PiperOrigin-RevId: 366935921
2021-03-22Fix and merge tcp_{outside_the_window,tcp_unacc_seq_ack}_closingZeling Feng
The tests were not using the correct windowSize so the testing segments were actually within the window for seqNumOffset=0 tests. The issue is already fixed by #5674. PiperOrigin-RevId: 364252630
2021-03-16Fix tcp_fin_retransmission_netstack_testZeling Feng
Netstack does not check ACK number for FIN-ACK packets and goes into TIMEWAIT unconditionally. Fixing the state machine will give us back the retransmission of FIN. PiperOrigin-RevId: 363301883
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
2021-02-25Move 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
2021-02-12Remove packetimpact test tcp_reorderingNayana Bidari
Remove flaky tcp_reordering_test as it does not check reordering. We have added new reorder tests in tcp_rack_test.go PiperOrigin-RevId: 357278769
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
2021-01-27Add support for more fields in netstack for TCP_INFONayana Bidari
This CL adds support for the following fields: - RTT, RTTVar, RTO - send congestion window (sndCwnd) and send slow start threshold (sndSsthresh) - congestion control state(CaState) - ReorderSeen PiperOrigin-RevId: 354195361
2021-01-22Add tests for RACKNayana Bidari
- Added packetimpact tests for RACK. PiperOrigin-RevId: 353282342
2020-12-05Fix zero receive window advertisements.Mithun Iyer
With the recent changes db36d948fa63ce950d94a5e8e9ebc37956543661, we try to balance the receive window advertisements between payload lengths vs segment overhead length. This works fine when segment size are much higher than the overhead, but not otherwise. In cases where the segment length is smaller than the segment overhead, we may end up not advertising zero receive window for long time and end up tail-dropping segments. This is especially pronounced when application socket reads are slow or stopped. In this change we do not grow the right edge of the receive window for smaller segment sizes similar to Linux. Also, we keep track of the socket buffer usage and let the window grow if the application is actively reading data. Fixes #4903 PiperOrigin-RevId: 345832012
2020-11-25[3/3] Support isolated containers for parallel packetimpact testsZeling Feng
To create DUTs in parallel, we need to create goroutines to do the setup. The old code base has a lot of t.Fatal(f) usage in those setup functions which is not great for this change: "FailNow must be called from the goroutine running the test or benchmark function, not from other goroutines created during the test" (https://golang.org/pkg/testing/#T.FailNow). - Cleanup all t.Fatal(f) usage in DUT.Prepare() - use goroutines to create DUTs in parallel PiperOrigin-RevId: 344275809
2020-11-24[2/3] Support isolated containers for parallel packetimpact testsZeling Feng
Added a new flag num_duts to the test runner to create multiple DUTs for the testbench can connect to. PiperOrigin-RevId: 344195435
2020-11-24Report correct pointer value for "bad next header" ICMP errorJulian Elischer
Because the code handles a bad header as "payload" right up to the last moment we need to make sure payload handling does not remove the error information. Fixes #4909 PiperOrigin-RevId: 344141690
2020-11-19Don't hold AddressEndpoints for multicast addressesGhanan Gowripalan
Group addressable endpoints can simply check if it has joined the multicast group without maintaining address endpoints. This also helps remove the dependency on AddressableEndpoint from GroupAddressableEndpoint. Now that group addresses are not tracked with address endpoints, we can avoid accidentally obtaining a route with a multicast local address. PiperOrigin-RevId: 343336912
2020-11-16Add packetimpact tests for ICMPv6 Error message for fragmentToshi Kikuchi

2020-10-29Add IPv4 reassembly packetimpact testArthur Sfez
The IPv6 reassembly test was also refactored to be easily extended with more cases. PiperOrigin-RevId: 339768605
2020-10-15Syncing packetimpact tests in different directoriesZeling Feng
By exposing an ALL_TESTS list in defs.bzl we can make sure all packetimpact users get to agree on the list of all tests. A defect in this approach is that we have to keep a list of packetimpact_testbench rules in the BUILD file. An helper validate_all_tests has been added to help keep BUILD and .bzl files in sync.

2020-08-04Enable "make packetimpact-tests" to work.Adin Scannell
This required minor fixes to the bazel wrapper. The "dut_platform" is also changed to "native" to line-up with the system call tests and remove the hard-coded "linux" and "netstack" strings.

2020-07-03Update build rule to appease deprecationTamir Duberstein
Before this change, running packetimpact tests produces: parameter 'direct' must contain a list of elements, and may no longer accept a depset. The deprecated behavior may be temporarily re-enabled by setting --incompatible_disable_depset_inputs=false The positional parameter to depset has been changed to mean `direct` rather than its previous meaning of `items`. The documentation[0] explains: A positional parameter distinct from other parameters for legacy support. If --incompatible_disable_depset_items is false, this parameter serves as the value of items. If --incompatible_disable_depset_items is true, this parameter serves as the value of direct. See the documentation for these parameters for more details.
