Safety of eBPF programs is statically determined by the verifier, which detects:
- loops
- out of range jumps
- unreachable instructions
- invalid instructions
- uninitialized register access
- uninitialized stack access
- misaligned stack access
- out of range stack access
- invalid calling convention
Is there something that documents exactly what conditions an eBPF
program must satisfy in order to be considered valid?
