Ideally, they should fail w/o your code change applied -* documentation changes - -Squash your commits into logical pieces of work that might want to be reviewed -separate from the rest of the PRs. Ideally, each commit should implement a -single idea, and the PR branch should pass the tests at every commit. GitHub -makes it easy to review the cumulative effect of many commits; so, when in -doubt, use smaller commits. - -PRs that fix issues should include a reference like `Closes #XXXX` in the -commit message so that github will automatically close the referenced issue -when the PR is merged. - -Contributors must assert that they are in compliance with the [Developer -Certificate of Origin 1.1](http://developercertificate.org/).

Your signature certifies that you wrote the patch or -otherwise have the right to pass it on as an open-source patch. - -### License - -The license of go-criu is the Apache 2.0 license. diff --git a/vendor/github.com/checkpoint-restore/go-criu/main.go b/vendor/github.com/checkpoint-restore/go-criu/main.go deleted file mode 100644 index cf94c376e..000000000 --- a/vendor/github.com/checkpoint-restore/go-criu/main.go +++ /dev/null @@ -1,250 +0,0 @@ -package criu - -import ( - "errors" - "fmt" - "os" - "os/exec" - "strconv" - "syscall" - - "github.com/checkpoint-restore/go-criu/rpc" - "github.com/golang/protobuf/proto" -) - -// Criu struct -type Criu struct { - swrkCmd *exec.Cmd - swrkSk *os.File -} - -// MakeCriu returns the Criu object required for most operations -func MakeCriu() *Criu { - return &Criu{} -} - -// Prepare sets up everything for the RPC communication to CRIU -func (c *Criu) Prepare() error { - fds, err := syscall.Socketpair(syscall.AF_LOCAL, syscall.SOCK_SEQPACKET, 0) - if err != nil { - return err - } - - cln := os.NewFile(uintptr(fds[0]), "criu-xprt-cln") - syscall.CloseOnExec(fds[0]) - srv := os.NewFile(uintptr(fds[1]), "criu-xprt-srv") - defer srv.Close() - - args := []string{"swrk", strconv.Itoa(fds[1])} - cmd := exec.Command("criu", args...) - - err = cmd.Start() - if err != nil { - cln.Close() - return err - } - - c.swrkCmd = cmd - c.swrkSk = cln - - return nil -} - -// Cleanup cleans up -func (c *Criu) Cleanup() { - if c.swrkCmd != nil { - c.swrkSk.Close() - c.swrkSk = nil - c.swrkCmd.Wait() - c.swrkCmd = nil - } -} - -func (c *Criu) sendAndRecv(reqB []byte) ([]byte, int, error) { - cln := c.swrkSk - _, err := cln.Write(reqB) - if err != nil { - return nil, 0, err - } - - respB := make([]byte, 2*4096) - n, err := cln.Read(respB) - if err != nil { - return nil, 0, err - } - - return respB, n, nil -} - -func (c *Criu) doSwrk(reqType rpc.CriuReqType, opts *rpc.CriuOpts, nfy Notify) error { - resp, err := c.doSwrkWithResp(reqType, opts, nfy) - if err != nil { - return err - } - respType := resp.GetType() - if respType != reqType { - return errors.New("unexpected responce") - } - - return nil -} - -func (c *Criu) doSwrkWithResp(reqType rpc.CriuReqType, opts *rpc.CriuOpts, nfy Notify) (*rpc.CriuResp, error) { - var resp *rpc.CriuResp - - req := rpc.CriuReq{ - Type: &reqType, - Opts: opts, - } - - if nfy != nil { - opts.NotifyScripts = proto.Bool(true) - } - - if c.swrkCmd == nil { - err := c.Prepare() - if err != nil { - return nil, err - } - - defer c.Cleanup() - } - - for { - reqB, err := proto.Marshal(&req) - if err != nil { - return nil, err - } - - respB, respS, err := c.sendAndRecv(reqB) - if err != nil { - return nil, err - } - - resp = &rpc.CriuResp{} - err = proto.Unmarshal(respB[:respS], resp) - if err != nil { - return nil, err - } - - if !resp.GetSuccess() { - return resp, fmt.Errorf("operation failed (msg:%s err:%d)", - resp.GetCrErrmsg(), resp.GetCrErrno()) - } - - respType := resp.GetType() - if respType != rpc.CriuReqType_NOTIFY { - break - } - if nfy == nil { - return resp, errors.New("unexpected notify") - } - - notify := resp.GetNotify() - switch notify.GetScript() { - case "pre-dump": - err = nfy.PreDump() - case "post-dump": - err = nfy.PostDump() - case "pre-restore": - err = nfy.PreRestore() - case "post-restore": - err = nfy.PostRestore(notify.GetPid()) - case "network-lock": - err = nfy.NetworkLock() - case "network-unlock": - err = nfy.NetworkUnlock() - case "setup-namespaces": - err = nfy.SetupNamespaces(notify.GetPid()) - case "post-setup-namespaces": - err = nfy.PostSetupNamespaces() - case "post-resume": - err = nfy.PostResume() - default: - err = nil - } - - if err != nil { - return resp, err - } - - req = rpc.CriuReq{ - Type: &respType, - NotifySuccess: proto.Bool(true), - } - } - - return resp, nil -} - -// Dump dumps a process -func (c *Criu) Dump(opts rpc.CriuOpts, nfy Notify) error { - return c.doSwrk(rpc.CriuReqType_DUMP, &opts, nfy) -} - -// Restore restores a process -func (c *Criu) Restore(opts rpc.CriuOpts, nfy Notify) error { - return c.doSwrk(rpc.CriuReqType_RESTORE, &opts, nfy) -} - -// PreDump does a pre-dump -func (c *Criu) PreDump(opts rpc.CriuOpts, nfy Notify) error { - return c.doSwrk(rpc.CriuReqType_PRE_DUMP, &opts, nfy) -} - -// StartPageServer starts the page server -func (c *Criu) StartPageServer(opts rpc.CriuOpts) error { - return c.doSwrk(rpc.CriuReqType_PAGE_SERVER, &opts, nil) -} - -// StartPageServerChld starts the page server and returns PID and port -func (c *Criu) StartPageServerChld(opts rpc.CriuOpts) (int, int, error) { - resp, err := c.doSwrkWithResp(rpc.CriuReqType_PAGE_SERVER_CHLD, &opts, nil) - if err != nil { - return 0, 0, err - } - - return int(resp.Ps.GetPid()), int(resp.Ps.GetPort()), nil -} - -// GetCriuVersion executes the VERSION RPC call and returns the version -// as an integer.

The code is based on the Go-based PHaul +implementation from the CRIU repository. For easier inclusion into other Go projects the +CRIU Go bindings have been moved to this repository. + +The Go bindings provide an easy way to use the CRIU RPC calls from Go without the need +to set up all the infrastructure to make the actual RPC connection to CRIU. + +The following example would print the version of CRIU: +```go +import ( + "log" + + "github.com/checkpoint/restore/go-criu/v5" +) + +func main() { + c := criu.MakeCriu() + version, err := c.GetCriuVersion() + if err != nil { + log.Fatalln(err) + } + log.Println(version) +} +``` + +or to just check if at least a certain CRIU version is installed: + +```go + c := criu.MakeCriu() + result, err := c.IsCriuAtLeast(31100) +``` + +## Releases + +The first go-criu release was 3.11 based on CRIU 3.11. The initial plan +was to follow CRIU so that go-criu would carry the same version number as +CRIU. + +As go-criu is imported in other projects and as Go modules are expected +to follow Semantic Versioning go-criu will also follow Semantic Versioning +starting with the 4.0.0 release. + +The following table shows the relation between go-criu and criu versions: + +| Major version | Latest release | CRIU version | +| -------------- | -------------- | ------------ | +| v5             | 5.0.0         | 3.15         | +| v4             | 4.1.0         | 3.14         | + +## How to contribute + +While bug fixes can first be identified via an "issue", that is not required. +It's ok to just open up a PR with the fix, but make sure you include the same +information you would have included in an issue - like how to reproduce it. + +PRs for new features should include some background on what use cases the +new code is trying to address. When possible and when it makes sense, try to +break-up larger PRs into smaller ones - it's easier to review smaller +code changes. But only if those smaller ones make sense as stand-alone PRs. + +Regardless of the type of PR, all PRs should include: +* well documented code changes +* additional testcases. Ideally, they should fail w/o your code change applied +* documentation changes + +Squash your commits into logical pieces of work that might want to be reviewed +separate from the rest of the PRs. Ideally, each commit should implement a +single idea, and the PR branch should pass the tests at every commit. GitHub +makes it easy to review the cumulative effect of many commits; so, when in +doubt, use smaller commits. + +PRs that fix issues should include a reference like `Closes #XXXX` in the +commit message so that github will automatically close the referenced issue +when the PR is merged. + +Contributors must assert that they are in compliance with the [Developer +Certificate of Origin 1.1](http://developercertificate.org/). This is achieved +by adding a "Signed-off-by" line containing the contributor's name and e-mail +to every commit message. Your signature certifies that you wrote the patch or +otherwise have the right to pass it on as an open-source patch. + +### License and copyright + +Unless mentioned otherwise in a specific file's header, all code in +this project is released under the Apache 2.0 license. + +The author of a change remains the copyright holder of their code +(no copyright assignment).

It is only possible to restore a container into a pod if it has been checkpointed out of pod. It is also not possible to restore a non pod container into a pod. The main reason this does not work is the PID namespace. If a non pod container is being restored in a pod with a shared PID namespace, at least one process in the restored container uses PID 1 which is already in use by the infrastructure container. If someone tries to restore container from a pod with a shared PID namespace without a shared PID namespace it will also fail because the resulting PID namespace will not have a PID 1.
