2018-11-20Fix recursive read lock taken on TaskSetFabricio Voznika
SyncSyscallFiltersToThreadGroup and Task.TheadID() both acquired TaskSet RWLock in R mode and could deadlock if a writer comes in between. PiperOrigin-RevId: 222313551 Change-Id: I4221057d8d46fec544cbfa55765c9a284fe7ebfa
2018-10-20Add more unimplemented syscall eventsFabricio Voznika
Added events for *ctl syscalls that may have multiple different commands. For runsc, each syscall event is only logged once. For *ctl syscalls, use the cmd as identifier, not only the syscall number. PiperOrigin-RevId: 218015941 Change-Id: Ie3c19131ae36124861e9b492a7dbe1765d9e5e59

2018-10-15Merge host.endpoint into host.ConnectedEndpointIan Gudger
host.endpoint contained duplicated logic from the sockerpair implementation and host.ConnectedEndpoint. Remove host.endpoint in favor of a host.ConnectedEndpoint wrapped in a socketpair end. PiperOrigin-RevId: 217240096 Change-Id: I4a3d51e3fe82bdf30e2d0152458b8499ab4c987c
2018-09-27Implement 'runsc kill --all'Fabricio Voznika
In order to implement kill --all correctly, the Sentry needs to track all tasks that belong to a given container. This change introduces ContainerID to the task, that gets inherited by all children. 'kill --all' then iterates over all tasks comparing the ContainerID field to find all processes that need to be signalled.

2018-08-31Document more task-goroutine-owned fields in kernel.Task.Jamie Liu
Task.creds can only be changed by the task's own set*id and execve syscalls, and Task namespaces can only be changed by the task's own unshare/setns syscalls. PiperOrigin-RevId: 211156279 Change-Id: I94d57105d34e8739d964400995a8a5d76306b2a0
2018-08-31Disintegrate kernel.TaskResources.Jamie Liu
This allows us to call kernel.FDMap.DecRef without holding mutexes cleanly. PiperOrigin-RevId: 211139657 Change-Id: Ie59d5210fb9282e1950e2e40323df7264a01bcec

2018-05-15sentry: Replaces saving of inet.Stack with retrieval via context.Kevin Krakauer
Previously, inet.Stack was referenced in 2 structs in sentry/socket that can be saved/restored. If an app is saved and restored on another machine, it may try to use the old stack, which will have been replaced by a new stack on the new machine.
