func (lp *LayeredProfile) LocalProfile() *Profile

LocalProfile returns the local profile associated with this layered profile.

func (*LayeredProfile) LockForUsage added in v0.6.0 

func (lp *LayeredProfile) LockForUsage()

func (*LayeredProfile) MarkStillActive added in v0.6.0 

func (lp *LayeredProfile) MarkStillActive()

MarkStillActive marks all the layers as still active.

func (*LayeredProfile) MarkUsed added in v0.4.1 

func (lp *LayeredProfile) MarkUsed()

MarkUsed marks the localProfile as used.

func (*LayeredProfile) MatchEndpoint added in v0.4.0 

func (lp *LayeredProfile) MatchEndpoint(ctx context.Context, entity *intel.Entity) (endpoints.EPResult, endpoints.Reason)

MatchEndpoint checks if the given endpoint matches an entry in any of the profiles. This functions requires the layered profile to be read locked.

func (*LayeredProfile) MatchFilterLists added in v0.4.0 

func (lp *LayeredProfile) MatchFilterLists(ctx context.Context, entity *intel.Entity) (endpoints.EPResult, endpoints.Reason)

MatchFilterLists matches the entity against the set of filter lists. This functions requires the layered profile to be read locked.

func (*LayeredProfile) MatchServiceEndpoint added in v0.4.0 

func (lp *LayeredProfile) MatchServiceEndpoint(ctx context.Context, entity *intel.Entity) (endpoints.EPResult, endpoints.Reason)

MatchServiceEndpoint checks if the given endpoint of an inbound connection matches an entry in any of the profiles. This functions requires the layered profile to be read locked.

func (*LayeredProfile) NeedsUpdate added in v0.6.0 

func (lp *LayeredProfile) NeedsUpdate() (outdated bool)

NeedsUpdate checks for outdated profiles.

func (*LayeredProfile) RevisionCnt added in v0.4.4 

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

RevisionCnt returns the current profile revision counter.

func (*LayeredProfile) SecurityLevel added in v0.4.0 

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 added in v0.6.0 

func (lp *LayeredProfile) UnlockForUsage()

UnlockForUsage unlocks the layered profile, including all layers individually.

func (*LayeredProfile) Update added in v0.4.0 

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Update checks for and replaces any outdated profiles.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
	// 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 New 

func New(source profileSource, id string, linkedPath string) *Profile

New returns a new Profile.

func (*Profile) AddEndpoint added in v0.4.0
