2020-12-17Add sandbox ID to state file nameFabricio Voznika
This allows to find all containers inside a sandbox more efficiently. This operation is required every time a container starts and stops, and previously required loading *all* container state files to check whether the container belonged to the sandbox. Apert from being inneficient, it has caused problems when state files are stale or corrupt, causing inavalability to create any container. Also adjust commands `list` and `debug` to skip over files that fail to load. Resolves #5052 PiperOrigin-RevId: 348050637

2020-12-16Add support to count the number of packets SACKed.Nayana Bidari
sacked_out is required in RACK to check the number of duplicate acknowledgements during updating the reorder window. If there is no reordering and the value for sacked_out is greater than the classic threshold value 3, then reorder window is set to zero. It is calculated by counting the number of segments sacked in the ACK and is reduced when a cumulative ACK is received which covers the SACK blocks. This value is set to zero when the connection enters recovery. PiperOrigin-RevId: 347872246

2020-12-16Ensure correctness of saved receive windowMithun Iyer
When the scaled receive window size > 65535 (max uint16), we advertise the scaled value as 65535, but are not adjusting the saved receive window value when doing so. This would keep our current window calculation logic to be incorrect, as the saved receive window value is different from what was advertised. Fixes #4903 PiperOrigin-RevId: 347771340

2020-12-15[syzkaller] Avoid AIOContext from resurrecting after being marked dead.Ayush Ranjan
syzkaller reported the closing of a nil channel. This is only possible when the AIOContext was destroyed twice. Some scenarios that could lead to this: - It died and then some called aioCtx.Prepare() on it and then killed it again which could cause the double destroy. The context could have been destroyed in between the call to LookupAIOContext() and Prepare(). - aioManager was destroyed but it did not update the contexts map. So Lookup could still return a dead AIOContext and then someone could call Prepare on it and kill it again. So added a check in aioCtx.Prepare() for the context being dead. This will prevent a dead context from resurrecting. Also refactored code to destroy the aioContext consistently. Earlier we were not munmapping the aioContexts that were destroyed upon aioManager destruction. Reported-by: syzbot+ef6a588d0ce6059991d2@syzkaller.appspotmail.com PiperOrigin-RevId: 347704347
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.

2020-12-12Reduce the memory overhead in IP fragment managementToshi Kikuchi
- Deep-copy pkt.Data and hold it instead of shallow-copy (vv.Clone). This allows the pkt's backing array, which includes the header portion, to be freed. - Remove fragHeap. The fragments are now held in holes struct instead. - Stop reserving the initial capacity of holes slice. PiperOrigin-RevId: 347198744

2020-12-11Add runsc symbolize command.Dean Deng
This command takes instruction pointers from stdin and converts them into their corresponding file names and line/column numbers in the runsc source code. The inputs are not interpreted as actual addresses, but as synthetic values that are exposed through /sys/kernel/debug/kcov. One can extract coverage information from kcov and translate those values into locations in the source code by running symbolize on the same runsc binary. This will allow us to generate syzkaller coverage reports. PiperOrigin-RevId: 347089624
2020-12-11Fix panic when IPv4 address is used in sendmsg for IPv6 socketsNayana Bidari
We do not rely on error for getsockopt options(which have boolean values) anymore. This will cause issue in sendmsg where we used to return error for IPV6_V6Only option. Fix the panic by returning error (for sockets other than TCP and UDP) if the address does not match the type(AF_INET/AF_INET6) of the socket. PiperOrigin-RevId: 347063838

For "hey", requests >= concurrency. b.N can be set by the --test.benchtime={b.N}x. The previous setting of b.N * c can be surprisingly slow for larger c. Set the requests to max(b.N, c) and log to the user if it is c. PiperOrigin-RevId: 347053675

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
