2020-12-14[netstack] Update raw socket and hostinet control message parsing.Ayush Ranjan
There are surprisingly few syscall tests that run with hostinet. For example running the following command only returns two results: `bazel query test/syscalls:all | grep hostnet` I think as a result, as our control messages evolved, hostinet was left behind. Update it to support all control messages netstack supports. This change also updates sentry's control message parsing logic to make it up to date with all the control messages we support.

2020-12-11[netstack] Decouple tcpip.ControlMessages from the IP control messges.Ayush Ranjan
tcpip.ControlMessages can not contain Linux specific structures which makes it painful to convert back and forth from Linux to tcpip back to Linux when passing around control messages in hostinet and raw sockets. Now we convert to the Linux version of the control message as soon as we are out of tcpip. PiperOrigin-RevId: 347027065

Inode number consistency checks are now skipped in save/restore tests for reasons described in greatest detail in StatTest.StateDoesntChangeAfterRename.

2020-02-18Enable IPV6_RECVTCLASS socket option for datagram socketsgVisor bot
Added the ability to get/set the IP_RECVTCLASS socket option on UDP endpoints. 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.

2020-01-27Update package locations.Adin Scannell

2019-12-02Support sending IP_TOS and IPV6_TCLASS control messages with hostinet sockets.Dean Deng
There are two potential ways of sending a TOS byte with outgoing packets: including a control message in sendmsg, or setting the IP_TOS/IPV6_TCLASS socket options (for IPV4 and IPV6 respectively). This change lets hostinet support the former. PiperOrigin-RevId: 283346737
