2021-06-30[syserror] Update syserror to linuxerr for EACCES, EBADF, and EPERM.Zach Koopmans
Update all instances of the above errors to the faster linuxerr implementation. With the temporary linuxerr.Equals(), no logical changes are made. PiperOrigin-RevId: 382306655

2021-06-29Sort children map before hashChong Cai
The unordered map may generate different hash due to its order. The children map needs to be sorted each time before hashing to avoid false verification failure due to the map. Store the sorted children map in verity dentry to avoid sorting it each time verification happens. Also serialize the whole VerityDescriptor struct to hash now that the map is removed from it.

2021-06-29[syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVALZach Koopmans
Remove three syserror entries duplicated in linuxerr. Because of the linuxerr.Equals method, this is a mere change of return values from syserror to linuxerr definitions. Done with only these three errnos as CLs removing all grow to a significantly large size. PiperOrigin-RevId: 382173835

2021-06-29Delete PID files right after they are readFabricio Voznika
The PID files are not used after they are read, so there is no point in keeping them around until the shim is deleted. Updates #6225 PiperOrigin-RevId: 382169916

2021-06-29Redirect all calls from `errdefs.ToGRPC` to `utils.ErrToGRPC`Fabricio Voznika
This is to ensure that Go 1.13 error wrapping is correctly translated to gRPC errors before returning from the shim. Updates #6225 PiperOrigin-RevId: 382120441
2021-06-29Fix TUN IFF_NO_PI bugliornm
When TUN is created with IFF_NO_PI flag, there will be no Ethernet header and no packet info, therefore, both read and write will fail. This commit fix this bug.

2021-06-28netstack: deflake TestSynRcvdBadSeqNumberKevin Krakauer
There was a race wherein Accept() could fail, then the handshake would complete, and then a waiter would be created to listen for the handshake. In such cases, no notification was ever sent and the test timed out. PiperOrigin-RevId: 381913041

2021-06-25Remove sndQueue as its pointless now.Bhasker Hariharan
sndQueue made sense when the worker goroutine and the syscall context held different locks. Now both lock the endpoint lock before doing anything which means adding to sndQueue is pointless as we move it to writeList immediately after that in endpoint.Write() by calling e.drainSendQueue.

2021-06-24Refactor default router state to off-link route stateGhanan Gowripalan
This change prepares for a later change which supports the NDP Route Information option to discover more-specific routes, as per RFC 4191. The newly introduced off-link route state will be used to hold both the state for default routers (which is a default (off-link) route through the router, and more-specific routes (which are routes through some router to some destination subnet more specific than the IPv6 empty subnet). Updates #6172. PiperOrigin-RevId: 381403761

2021-06-23Do not attempt to kill stopped exec processesNoah Fontes
While #6204 addressed the stopped state for handling signals in the main process, it did not update exec processes in the same way. This change mirrors that adjustment for exec processes.
2021-06-23Ensure shim propagates errors over gRPC correctlyNoah Fontes
This change wraps containerd's errdefs.ToGRPC function with one that understands Go 1.13-style error wrapping style, which is used pervasively throughout the shim. With this change, errors that have been marked with, e.g., `errdefs.ErrNotFound`, will be correctly propagated back to the containerd server.
