2021-06-22[syserror] Add conversions to linuxerr with temporary Equals method.Zach Koopmans
Add Equals method to compare syserror and unix.Errno errors to linuxerr errors. This will facilitate removal of syserror definitions in a followup, and finding needed conversions from unix.Errno to linuxerr. PiperOrigin-RevId: 380909667
2021-06-22runsc: don't kill sandbox, let it stop properlyAndrei Vagin
The typical sequence of calls to start a container looks like this ct, err := container.New(conf, containerArgs) defer ct.Destroy() ct.Start(conf) ws, err := ct.Wait() For the root container, ct.Destroy() kills the sandbox process. This doesn't look like a right wait to stop it. For example, all ongoing rpc calls are aborted in this case. If everything is going alright, we can just wait and it will exit itself.

2021-05-07Init all vCPU when initializing machine on ARM64howard zhang
This patch is to solve problem that vCPU timer mess up when adding vCPU dynamically on ARM64, for detailed information please refer to: https://github.com/google/gvisor/issues/5739 There is no influence on x86 and here are main changes for ARM64: 1. create maxVCPUs number of vCPU in machine initialization 2. we want to sync gvisor vCPU number with host CPU number, so use smaller number between runtime.NumCPU and KVM_CAP_MAX_VCPUS to be maxVCPUS 3. put unused vCPUs into architecture-specific map initialvCPUs 4. When machine need to bind a new vCPU with tid, rather than creating new one, it would pick a vCPU from map initalvCPUs 5. change the setSystemTime function. When vCPU number increasing, the time cost for function setTSC(use syscall to set cntvoff) is liner growth from around 300 ns to 100000 ns, and this leads to the function setSystemTimeLegacy can not get correct offset value. 6. initializing StdioFDs and goferFD before a platform to avoid StdioFDs confects with vCPU fds Signed-off-by: howard zhang <howard.zhang@arm.com>

2021-05-05Fixes to runsc cgroupsFabricio Voznika
When loading cgroups for another process, `/proc/self` was used in a few places, causing the end state to be a mix of the process and self. This is now fixes to always use the proper `/proc/[pid]` path. Added net_prio and net_cls to the list of optional controllers. This is to allow runsc to execute then these cgroups are disabled as long as there are no net_prio and net_cls limits that need to be applied. Deflake TestMultiContainerEvent.

2021-05-04Make Mount.Type optional for bind mountsFabricio Voznika
According to the OCI spec Mount.Type is an optional field and it defaults to "bind" when any of "bind" or "rbind" is included in Mount.Options. Also fix the shim to remove bind/rbind from options when mount is converted from bind to tmpfs inside the Sentry. Fixes #2330 Fixes #3274 PiperOrigin-RevId: 371996891
