2021-07-21buildkite: update GoKevin Krakauer
#6322 tried to update Go to 1.16, but existing nodes fail to upgrade due to the presence of old Go [1]. Specifically when trying to add Go to `/usr/bin`: ``` ln: failed to create symbolic link '/usr/bin/go': File exists ``` Also: - Removing `golang-go` also removes apt installs of `gcc` and `pkg-config`, so those are installed explicitly. - Add `-c` to wget, which will prevent re-downloading Go for each run. - Disable GO111MODULE when building cri-tools and containerd, since we're using pre-module versions of each. 1 - https://buildkite.com/gvisor/pipeline/builds/7285#3593244c-e411-472d-804a-9c7fbbd24762 PiperOrigin-RevId: 386106881

2021-07-20Don't kill container when volume is unmountedFabricio Voznika
The gofer session is killed when a gofer backed volume is unmounted. The gofer monitor catches the disconnect and kills the container. This changes the gofer monitor to only care about the rootfs connections, which cannot be unmounted. Fixes #6259 PiperOrigin-RevId: 385929039

2021-07-13Do not require O_PATH flag to enable verityChong Cai
Remove the hack in gVisor vfs that allows verity to bypass the O_PATH check, since ioctl is not allowed on fds opened with O_PATH in linux. Verity still opens the lowerFD with O_PATH to open it as a symlink, but the API no longer expects O_PATH to open a fd to be verity enabled. Now only O_FOLLOW should be specified when opening and enabling verity features. PiperOrigin-RevId: 384567833
