2020-03-12Kill sandbox process when parent process terminatesFabricio Voznika
When the sandbox runs in attached more, e.g. runsc do, runsc run, the sandbox lifetime is controlled by the parent process. This wasn't working in all cases because PR_GET_PDEATHSIG doesn't propagate through execve when the process changes uid/gid. So it was getting dropped when the sandbox execve's to change to user nobody. PiperOrigin-RevId: 300601247

2019-09-05Ignore the root container when calculating oom_score_adj for the sandbox.Ian Lewis
This is done because the root container for CRI is the infrastructure (pause) container and always gets a low oom_score_adj. We do this to ensure that only the oom_score_adj of user containers is used to calculated the sandbox oom_score_adj. Implemented in runsc rather than the containerd shim as it's a bit cleaner to implement here (in the shim it would require overwriting the oomScoreAdj and re-writing out the config.json again). This processing is Kubernetes(CRI) specific but we are currently only supporting CRI for multi-container support anyway. PiperOrigin-RevId: 267507706

2019-06-12Allow 'runsc do' to run without rootFabricio Voznika
'--rootless' flag lets a non-root user execute 'runsc do'. The drawback is that the sandbox and gofer processes will run as root inside a user namespace that is mapped to the caller's user, intead of nobody. And network is defaulted to '--network=host' inside the root network namespace. On the bright side, it's very convenient for testing: runsc --rootless do ls runsc --rootless do curl www.google.com PiperOrigin-RevId: 252840970

2019-06-11Add support to mount pod shared tmpfs mountsFabricio Voznika
Parse annotations containing 'gvisor.dev/spec/mount' that gives hints about how mounts are shared between containers inside a pod. This information can be used to better inform how to mount these volumes inside gVisor. For example, a volume that is shared between containers inside a pod can be bind mounted inside the sandbox, instead of being two independent mounts. For now, this information is used to allow the same tmpfs mounts to be shared between containers which wasn't possible before. PiperOrigin-RevId: 252704037

2019-03-18Add support for mount propagationFabricio Voznika
Properly handle propagation options for root and mounts. Now usage of mount options shared, rshared, and noexec cause error to start. shared/ rshared breaks sandbox=>host isolation. slave however can be supported because changes propagate from host to sandbox. Root FS setup moved inside the gofer. Apart from simplifying the code, it keeps all mounts inside the namespace. And they are torn down when the namespace is destroyed (DestroyFS is no longer needed). PiperOrigin-RevId: 239037661 Change-Id: I8b5ee4d50da33c042ea34fa68e56514ebe20e6e0

2018-10-18Resolve mount paths while setting up root fs mountFabricio Voznika
It's hard to resolve symlinks inside the sandbox because rootfs and mounts may be read-only, forcing us to create mount points inside lower layer of an overlay, **before** the volumes are mounted. Since the destination must already be resolved outside the sandbox when creating mounts, take this opportunity to rewrite the spec with paths resolved. "runsc boot" will use the "resolved" spec to load mounts. In addition, symlink traversals were disabled while mounting containers inside the sandbox. It haven't been able to write a good test for it. So I'm relying on manual tests for now. PiperOrigin-RevId: 217749904 Change-Id: I7ac434d5befd230db1488446cda03300cc0751a9
