func (*LayeredProfile) RevisionCnt

func (lp *LayeredProfile) RevisionCnt() (revisionCounter uint64)

RevisionCnt returns the current profile revision counter.

func (*LayeredProfile) SecurityLevel

func (lp *LayeredProfile) SecurityLevel() uint8

SecurityLevel returns the highest security level of all layered profiles. This function is atomic and does not require any locking.

func (*LayeredProfile) UnlockForUsage

func (lp *LayeredProfile) UnlockForUsage()

UnlockForUsage unlocks the layered profile, including all layers individually.

func (*LayeredProfile) Update

func (lp *LayeredProfile) Update() (revisionCounter uint64)

Update checks for and replaces any outdated profiles.

type Profile

type Profile struct {
	record.Base
	sync.RWMutex

	// ID is a unique identifier for the profile.
	ID string // constant
	// Source describes the source of the profile.
	Source profileSource // constant
	// Name is a human readable name of the profile. It
	// defaults to the basename of the application.
	Name string
	// Description may holds an optional description of the
	// profile or the purpose of the application.
	Description string
	// Homepage may refer the the website of the application
	// vendor.
	Homepage string
	// Icon holds the icon of the application. The value
	// may either be a filepath, a database key or a blob URL.
	// See IconType for more information.
	Icon string
	// IconType describes the type of the Icon property.
	IconType iconType
	// LinkedPath is a filesystem path to the executable this
	// profile was created for.
	LinkedPath string // constant
	// LinkedProfiles is a list of other profiles
	LinkedProfiles []string
	// SecurityLevel is the mininum security level to apply to
	// connections made with this profile.
	// Note(ppacher): we may deprecate this one as it can easily
	//			      be "simulated" by adjusting the settings
	//				  directly.
	SecurityLevel uint8
	// Config holds profile specific setttings. It's a nested
	// object with keys defining the settings database path. All keys
	// until the actual settings value (which is everything that is not
	// an object) need to be concatenated for the settings database
	// path.
	Config map[string]interface{}

	// ApproxLastUsed holds a UTC timestamp in seconds of
	// when this Profile was approximately last used.
	// For performance reasons not every single usage is saved.
	ApproxLastUsed int64
	// LastEdited hols the UTC timestamp in seconds when the profile was last
	// edited by the user. This is not set automatically, but has to be manually
	// set by the user interface.
	LastEdited int64
	// Created holds the UTC timestamp in seconds when the
	// profile has been created.
	Created int64

	// Internal is set to true if the profile is attributed to a
	// Portmaster internal process. Internal is set during profile
	// creation and may be accessed without lock.
	Internal bool
	// contains filtered or unexported fields
}

Profile is used to predefine a security profile for applications.

func EnsureProfile

func EnsureProfile(r record.Record) (*Profile, error)

EnsureProfile ensures that the given record is a *Profile, and returns it.

func GetProfile

func GetProfile(source profileSource, id, linkedPath string) (
	profile *Profile,
	err error,
)

GetProfile fetches a profile. This function ensures that the loaded profile is shared among all callers. You must always supply both the scopedID and linkedPath parameters whenever available. The linkedPath is used as the key for locking concurrent requests, so it must be supplied if available. If linkedPath is not supplied, source and id make up the key instead.

func New

func New(
	source profileSource,
	id string,
	linkedPath string,
	customConfig map[string]interface{},
) *Profile

New returns a new Profile. Optionally, you may supply custom configuration in the flat (key=value) form.

func (*Profile) AddEndpoint

func (profile *Profile) AddEndpoint(newEntry string)

AddEndpoint adds an endpoint to the endpoint list, saves the profile and reloads the configuration.

func (*Profile) AddServiceEndpoint

func (profile *Profile) AddServiceEndpoint(newEntry string)

AddServiceEndpoint adds a service endpoint to the endpoint list, saves the profile and reloads the configuration.

func (*Profile) GetEndpoints

func (profile *Profile) GetEndpoints() endpoints.Endpoints

GetEndpoints returns the endpoint list of the profile. This functions requires the profile to be read locked.

func (*Profile) GetServiceEndpoints

func (profile *Profile) GetServiceEndpoints() endpoints.Endpoints

GetServiceEndpoints returns the service endpoint list of the profile. This functions requires the profile to be read locked.

func (*Profile) IsOutdated

func (profile *Profile) IsOutdated() bool

IsOutdated returns whether the this instance of the profile is marked as outdated.

func (*Profile) LastActive

func (profile *Profile) LastActive() int64

LastActive returns the unix timestamp when the profile was last marked as still active.

func (*Profile) LayeredProfile

func (profile *Profile) LayeredProfile() *LayeredProfile

LayeredProfile returns the layered profile associated with this profile.

func (*Profile) MarkStillActive

func (profile *Profile) MarkStillActive()

MarkStillActive marks the profile as still active.

func (*Profile) MarkUsed

func (profile *Profile) MarkUsed() (changed bool)

MarkUsed updates ApproxLastUsed when it's been a while and saves the profile if it was changed.

func (*Profile) Save

func (profile *Profile) Save() error

Save saves the profile to the database

func (*Profile) ScopedID

func (profile *Profile) ScopedID() string

ScopedID returns the scoped ID (Source + ID) of the profile.

func (*Profile) String

func (profile *Profile) String() string

String returns a string representation of the Profile.

func (*Profile) UpdateMetadata

func (profile *Profile) UpdateMetadata(binaryPath string) (changed bool)

UpdateMetadata updates meta data fields on the profile and returns whether the profile was changed. If there is data that needs to be fetched from the operating system, it will start an async worker to fetch that data and save the profile afterwards.
