This CL adds terminal support for "docker exec". We previously only supported consoles for the container process, but not exec processes. The SYS_IOCTL syscall was added to the default seccomp filter list, but only for ioctls that get/set winsize and termios structs. We need to allow these ioctl for all containers because it's possible to run "exec -ti" on a container that was started without an attached console, after the filters have been installed. Note that control-character signals are still not properly supported. Tested with: $ docker run --runtime=runsc -it alpine In another terminial: $ docker exec -it <containerid> /bin/sh PiperOrigin-RevId: 210185456 Change-Id: I6d2401e53a7697bb988c120a8961505c335f96d9 |
