2021-03-08Avoid a race with test peer advert and DUT sendMithun Iyer
Fix a race where the DUT could send out test data before it received the peer window advertisement. Such a race results in the DUT taking longer time to retransmit zero window probe, thus causing the test to fail receiving the last expected probe. To ensure this ordering, piggyback a non-zero payload with the zero window advertisement and let the DUT receive that, before continuing with the test. PiperOrigin-RevId: 361640241

2021-03-06[op] Replace syscall package usage with golang.org/x/sys/unix in runsc/.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: 361381490

2021-03-03Make dedicated methods for data operations in PacketBufferTing-Yu Wang
One of the preparation to decouple underlying buffer implementation. There are still some methods that tie to VectorisedView, and they will be changed gradually in later CLs. This CL also introduce a new ICMPv6ChecksumParams to replace long list of parameters when calling ICMPv6Checksum, aiming to be more descriptive. PiperOrigin-RevId: 360778149

2021-03-03Assert UpdatedAtNanos in neighbor cache testsSam Balana
Changes the neighbor_cache_test.go tests to always assert UpdatedAtNanos. Completes the assertion of UpdatedAtNanos in every NUD test, a field that was historically not checked due to the lack of a deterministic, controllable clock. This is no longer true with the tcpip.Clock interface. While the tests have been adjusted to use Clock, asserting by the UpdatedAtNanos was neglected. Fixes #4663 PiperOrigin-RevId: 360730077

This validates that struct fields if annotated with "// checklocks:mu" where "mu" is a mutex field in the same struct then access to the field is only done with "mu" locked.

Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.
