Hooks Package Documentation
The hooks package contains the user-space Go code responsible for
loading eBPF hooks and eBPF maps, which are used to instrument the user
API. This package is utilized by the CLI commands. Additionally, it
launches proxies on a range of local ports to capture egress calls.

Functions ¶
func LaunchPerfBufferConsumers ¶
func LaunchPerfBufferConsumers(objs bpfObjects, connectionFactory *connection.Factory, stopper chan os.Signal, logger *zap.Logger)
LaunchPerfBufferConsumers launches socket events
Types ¶
type Hook ¶
type Hook struct {
platform.TestCaseDB
// contains filtered or unexported fields
}
func (*Hook) CleanProxyEntry ¶
func (*Hook) GetConfigMocks ¶
func (*Hook) GetDepsSize ¶
func (*Hook) GetDestinationInfo ¶
func (*Hook) GetTcsMocks ¶
func (*Hook) IsDockerRelatedCmd ¶
It checks if the cmd is related to docker or not, it also returns if its a docker compose file
func (*Hook) LaunchUserApplication ¶
func (*Hook) LoadHooks ¶
LoadHooks is used to attach the eBPF hooks into the linux kernel. Hooks are attached for outgoing and incoming network requests.
proxyPorts is used for redirecting outgoing network calls to the unoccupied proxy server.
$BPF_CLANG and $BPF_CFLAGS are set by the Makefile.
func (*Hook) PrintRedirectProxyMap ¶
func (h *Hook) PrintRedirectProxyMap()
// printing the whole map
func (*Hook) SendKeployPid ¶
func (*Hook) SendNameSpaceId ¶
This function is helpful when user application in running inside a docker container.
func (*Hook) SendProxyInfo ¶
This function sends the IP and Port of the running proxy in the eBPF program.
func (*Hook) SetConfigMocks ¶
func (*Hook) SetKeployModeInKernel ¶
func (*Hook) SetTcsMocks ¶
func (*Hook) StopUserApplication ¶
func (h *Hook) StopUserApplication()
StopUserApplication stops the user application
