2019-08-29Compile procter binaries during image creation.Nicolas Lacasse
Using "go run ..." in the ENTRYPOINT causes the go compiler to run each time the container is started. We can just compile the binary once as part of the image. PiperOrigin-RevId: 266212462

2019-08-27Populate link address cache at dispatchTamir Duberstein
This allows the stack to learn remote link addresses on incoming packets, reducing the need to ARP to send responses. This also reduces the number of round trips to the system clock, since that may also prove to be performance-sensitive. Fixes #739. PiperOrigin-RevId: 265815816

2019-08-26netstack/tcp: Add LastAck transition.Rahat Mahmood
Add missing state transition to LastAck, which should happen when the endpoint has already recieved a FIN from the remote side, and is sending its own FIN. PiperOrigin-RevId: 265568314
2019-08-26Add support for Intel cache CPUID leafsMichael Pratt
This exposes L1, L2, etc. cache sizes, cache line size, etc. Across S/R, everything except cache line size can differ from the host. This is because cache line size is critical for correct use of CLFLUSH / CLFLUSHOPT, but as far as I know, the other cache parameters can only affect performance, not correctness. AMD uses different leafs for cache information, which are not yet supported. fail. There are no known cases of cache line size other than 64 in the fleet. PiperOrigin-RevId: 265544786

2019-08-26Prevent a network endpoint to send/rcv if its address was removedChris Kuiper
This addresses the problem where an endpoint has its address removed but still has outstanding references held by routes used in connected TCP/UDP sockets which prevent the removal of the endpoint. The fix adds a new "expired" flag to the referenced network endpoint, which is set when an endpoint has its address removed. Incoming packets are not delivered to an expired endpoint (unless in promiscuous mode), while sending outgoing packets triggers an error to the caller (unless in spoofing mode). In addition, a few helper functions were added to stack_test.go to reduce code duplications. PiperOrigin-RevId: 265514326

2019-08-23Second try at flaky futex test.Zach Koopmans
The flake had the call to futex_unlock_pi() returning EINVAL with the FUTEX_OWNER_DIED set. In this case, userspace has to clean up stale state. So instead of calling FUTEX_UNLOCK_PI outright, we'll use the advised atomic compare_exchange as advised in the man page. PiperOrigin-RevId: 265163920

2019-08-22test: set shard_count to 5 by defaultAndrei Vagin
In cl/264434674 and cl/264498919, we stop running test cases in parallel to not overload test hosts. But now tests requires more time to run, so we need to increase a default number of shards or a default test timeout. Let's start with increasing the number of shards and see how it will works.

2019-08-21Support binding to multicast and broadcast addressesChris Kuiper
This fixes the issue of not being able to bind to either a multicast or broadcast address as well as to send and receive data from it. The way to solve this is to treat these addresses similar to the ANY address and register their transport endpoint ID with the global stack's demuxer rather than the NIC's. That way there is no need to require an endpoint with that multicast or broadcast address. The stack's demuxer is in fact the only correct one to use, because neither broadcast- nor multicast-bound sockets care which NIC a packet was received on (for multicast a join is still needed to receive packets on a NIC). I also took the liberty of refactoring udp_test.go to consolidate a lot of duplicate code and make it easier to create repetitive tests that test the same feature for a variety of packet and socket types. For this purpose I created a "flowType" that represents two things: 1) the type of packet being sent or received and 2) the type of socket used for the test. E.g., a "multicastV4in6" flow represents a V4-mapped multicast packet run through a V6-dual socket. This allows writing significantly simpler tests. A nice example is testTTL().
