tor/changes/bug13290-avoid-div-zero-circuitstatus-pareto

  o Minor bugfixes:
    - In circuit_build_times_calculate_timeout() in circuitstats.c, avoid
      dividing by zero in the pareto calculations. This traps under
      clang -fsanitize=undefined-trap -fsanitize-undefined-trap-on-error.
      Fixes bug 13290.
Avoid division by zero in circuitstats pareto In circuit_build_times_calculate_timeout() in circuitstats.c, avoid dividing by zero in the pareto calculations. If either the alpha or p parameters are 0, we would divide by zero, yielding an infinite result; which would be clamped to INT32_MAX anyway. So rather than dividing by zero, we just skip the offending calculation(s), and use INT32_MAX for the result. Division by zero traps under clang -fsanitize=undefined-trap -fsanitize-undefined-trap-on-error. 2014-09-29 12:24:40 +02:00			`o Minor bugfixes:`
