	// Name is the default filesystem name.
	Name = "proc"
)

Functions

func GetMetadata

func GetMetadata(ctx context.Context, mm *mm.MemoryManager, buf *bytes.Buffer, t MetadataType) error

GetMetadata fetches the process's metadata of type t and writes it into buf. The process is identified by mm.

Types

type FilesystemType

type FilesystemType struct{}

FilesystemType is the factory class for procfs.

func (FilesystemType) GetFilesystem

func (ft FilesystemType) GetFilesystem(ctx context.Context, vfsObj *vfs.VirtualFilesystem, creds *auth.Credentials, source string, opts vfs.GetFilesystemOptions) (*vfs.Filesystem, *vfs.Dentry, error)

GetFilesystem implements vfs.FilesystemType.GetFilesystem.

func (FilesystemType) Name

func (FilesystemType) Name() string

Name implements vfs.FilesystemType.Name.

func (FilesystemType) Release

func (FilesystemType) Release(ctx context.Context)

Release implements vfs.FilesystemType.Release.

func (*FilesystemType) StateFields

func (ft *FilesystemType) StateFields() []string

func (*FilesystemType) StateLoad

func (ft *FilesystemType) StateLoad(stateSourceObject state.Source)

+checklocksignore

func (*FilesystemType) StateSave

func (ft *FilesystemType) StateSave(stateSinkObject state.Sink)

+checklocksignore

func (*FilesystemType) StateTypeName

func (ft *FilesystemType) StateTypeName() string

type InternalData

type InternalData struct {
	Cgroups map[string]string
}

InternalData contains internal data passed in to the procfs mount via vfs.GetFilesystemOptions.InternalData.

func (*InternalData) StateFields

func (i *InternalData) StateFields() []string

func (*InternalData) StateLoad

func (i *InternalData) StateLoad(stateSourceObject state.Source)

+checklocksignore

func (*InternalData) StateSave

func (i *InternalData) StateSave(stateSinkObject state.Sink)

+checklocksignore

func (*InternalData) StateTypeName

func (i *InternalData) StateTypeName() string

type MetadataType

type MetadataType int

MetadataType enumerates the types of metadata that is exposed through proc.

const (
	// Cmdline represents /proc/[pid]/cmdline.
	Cmdline MetadataType = iota

	// Environ represents /proc/[pid]/environ.
	Environ
)
