Functions

func BroaderPermission

func BroaderPermission(a, b model.ACLPermission) bool

BroaderPermission returns true if a offers strictly more permissions than b. Unknown ACLPermission will panic.

func MigrateImportPermissions

func MigrateImportPermissions(ctx context.Context, kvStore kv.Store, cfg *config.Config) error

func MigrateToACL

func MigrateToACL(ctx context.Context, kvStore kv.Store, cfg *config.Config, logger logging.Logger, version int, force bool) error

Types

type ACLsMigrator

type ACLsMigrator struct {
	Actions map[model.ACLPermission]map[string]struct{}
	// contains filtered or unexported fields
}

ACLsMigrator migrates from policies to ACLs.

func NewACLsMigrator

func NewACLsMigrator(svc auth.Service, doUpdate bool) *ACLsMigrator

NewACLsMigrator returns an ACLsMigrator. That ACLsMigrator will only check (change nothing) if doUpdate is false.

func (*ACLsMigrator) ComputeAddedActions

func (mig *ACLsMigrator) ComputeAddedActions(permission model.ACLPermission, alreadyAllowedActions map[string]struct{}) []string

ComputeAddedActions returns the list of actions that permission allows that are not in alreadyAllowedActions.

func (*ACLsMigrator) ComputePermission

func (mig *ACLsMigrator) ComputePermission(ctx context.Context, actions []string) (model.ACLPermission, error)

ComputePermission returns ACL permission for actions and the actions that applying that permission will add to it.

func (*ACLsMigrator) GetMinPermission

func (mig *ACLsMigrator) GetMinPermission(action string) model.ACLPermission

func (*ACLsMigrator) NewACLForPolicies

func (mig *ACLsMigrator) NewACLForPolicies(ctx context.Context, policies []*model.Policy) (acl *model.ACL, warn error, err error)

NewACLForPolicies converts policies of group name to an ACL. warn summarizes all losses in converting policies to ACL. err holds an error if conversion failed.
