From 5a421058a07477e23f6ca23bb510894419224080 Mon Sep 17 00:00:00 2001 From: Ghanan Gowripalan Date: Fri, 25 Oct 2019 16:05:31 -0700 Subject: Validate the checksum for incoming ICMPv6 packets This change validates the ICMPv6 checksum field before further processing an ICMPv6 packet. Tests: Unittests to make sure that only ICMPv6 packets with a valid checksum are accepted/processed. Existing tests using checker.ICMPv6 now also check the ICMPv6 checksum field.

Note, Router Solicitations will only be sent when the stack has forwarding disabled. Tests: Unittests to make sure that the initial Router Solicitations are sent as configured. The tests also validate the sent Router Solicitations' fields.

If enabled, traffic class from the incoming Network Header passed as ancillary data in the ControlMessages. Adding Get/SetSockOptBool to decrease the overhead of getting/setting simple options. (This was absorbed in a CL that will be landing before this one). Test: * Added unit test to udp_test.go that tests getting/setting as well as verifying that we receive expected TOS from incoming packet. * Added a syscall test for verifying getting/setting * Removed test skip for existing syscall test to enable end to end test.

Bhasker Hariharan Date: Tue, 14 Apr 2020 19:32:32 -0700 Subject: Reduce flakiness in tcp_test. Tests now use a MinRTO of 3s instead of default 200ms. This reduced flakiness in a lot of the congestion control/recovery tests which were flaky due to retransmit timer firing too early in case the test executors were overloaded. This change also bumps some of the timeouts in tests which were too sensitive to timer variations and reduces the number of slow start iterations which can make the tests run for too long and also trigger retansmit timeouts etc if the executor is overloaded.
