#! /usr/bin/python3 # # This script generates a BPF program with structure inspired by trace.py. The # generated program operates on PID-indexed stacks. Generally speaking, # bookkeeping is done at every intermediate function kprobe/kretprobe to enforce # the goal of "fail iff this call chain and these predicates". # # Top level functions(the ones at the end of the call chain) are responsible for # creating the pid_struct and deleting it from the map in kprobe and kretprobe # respectively. # # Intermediate functions(between should_fail_whatever and the top level # functions) are responsible for updating the stack to indicate "I have been # called and one of my predicate(s) passed" in their entry probes. In their exit # probes, they do the opposite, popping their stack to maintain correctness. # This implementation aims to ensure correctness in edge cases like recursive # calls, so there's some additional information stored in pid_struct for that. # # At the bottom level function(should_fail_whatever), we do a simple check to # ensure all necessary calls/predicates have passed before error injection. # # Note: presently there are a few hacks to get around various rewriter/verifier # issues. # # Note: this tool requires: # - CONFIG_BPF_KPROBE_OVERRIDE # # USAGE: inject [-h] [-I header] [-P probability] [-v] mode spec # # Copyright (c) 2018 Facebook, Inc. # Licensed under the Apache License, Version 2.0 (the "License") # # 16-Mar-2018 Howard McLauchlan Created this. import argparse import re from bcc import BPF class Probe: errno_mapping = { "kmalloc": "-ENOMEM", "bio": "-EIO", "alloc_page" : "true", } @classmethod def configure(cls, mode, probability, count): cls.mode = mode cls.probability = probability cls.count = count def __init__(self, func, preds, length, entry): # length of call chain self.length = length self.func = func self.preds = preds self.is_entry = entry def _bail(self, err): raise ValueError("error in probe '%s': %s" % (self.spec, err)) def _get_err(self): return Probe.errno_mapping[Probe.mode] def _get_if_top(self): # ordering guarantees that if this function is top, the last tup is top chk = self.preds[0][1] == 0 if not chk: return "" if Probe.probability == 1: early_pred = "false" else: early_pred = "bpf_get_prandom_u32() > %s" % str(int((1<<32)*Probe.probability)) # init the map # don't do an early exit here so the singular case works automatically # have an early exit for probability option enter = """ /* * Early exit for probability case */ if (%s) return 0;
