syscall/invalid
Micro-benchmark measuring invalid system call rejection latency.
Benchmark Profile
Type: Micro
Kernel subsystem: Syscall dispatch, seccomp filter path
Coverage: Directly measured
Topology: Single role: executer
Overview
Measures how quickly the kernel rejects an invalid syscall number. A direct measurement of the syscall dispatch fast-path and seccomp filter overhead for unknown syscalls.
