2020-12-17[netstack] Implement MSG_ERRQUEUE flag for recvmsg(2).Ayush Ranjan
Introduces the per-socket error queue and the necessary cmsg mechanisms. PiperOrigin-RevId: 348028508
2020-12-15[netstack] Make recvmsg(2) call to host in hostinet even if dst is empty.Ayush Ranjan
We want to make the recvmsg syscall to the host regardless of if the dst is empty or not so that: - Host can populate the control messages if necessary. - Host can return sender address. - Host can return appropriate errors. Earlier because we were using the IOSequence.CopyOutFrom() API, the usermem package does not even call the Reader function if the destination is empty (as an optimization).

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
