2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-12-24Enable IP_RECVTOS socket option for datagram socketsRyan Heacock
Added the ability to get/set the IP_RECVTOS socket option on UDP endpoints. If enabled, TOS from the incoming Network Header passed as ancillary data in the ControlMessages. 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 PiperOrigin-RevId: 287029703

2019-11-06Use PacketBuffers, rather than VectorisedViews, in netstack.Kevin Krakauer
PacketBuffers are analogous to Linux's sk_buff. They hold all information about a packet, headers, and payload. This is important for: * iptables to access various headers of packets * Preventing the clutter of passing different net and link headers along with VectorisedViews to packet handling functions. This change only affects the incoming packet path, and a future change will change the outgoing path.

2019-10-30Deep copy dispatcher views.Kevin Krakauer
When VectorisedViews were passed up the stack from packet_dispatchers, we were passing a sub-slice of the dispatcher's views fields. The dispatchers then immediately set those views to nil. This wasn't caught before because every implementer copied the data in these views before returning. PiperOrigin-RevId: 277615351
