4482669d7e C++: Add a new 'InvalidPointerDeref' query to experimental. 2022-09-15 17:47:15 +01:00
Mathias Vorreiter Pedersen
b8a5aa5d85 C++: Fix a couple of range analysis issues:
1. The new query is expecting pointer arithmetic operations to generate
range-analysis bounds, but this wasn't true on main.
2. The bounds generated by `boundFlowCond` was incorrectly inferred as
non-strict when comparing a pointers (unlike when comparing values of
integral types). This gave FPs in the new query.

This also fixes a couple of missing results in existing queries that
use the new range-analysis library.

02772ed20c Revert changes to .gitignore and .clang-format
because they are potentially too global, belong in a separate PR.

ca162a4365 C++: complete initial implementation of cpp/missing-check-scanf
There are still some remaining FPs (haven't fully tested them)
that should be ironed out in a follow-up to increase the precision, e.g.:

  * if scanf(&i) != 1 return
    if maybe() && scanf(&i) != 1 return
    use(i) // should be OK on both counts

  * The minimum guard constant for the *_s variants may not be right.

  * int i[2]
    scanf(i, i+1) // second i is flagged as a use of the first

  * Maybe loosen the "unguarded or badly guarded use() = bad" policy to
    "unguarded but already-initialized = good" and "badly guarded = bad",
    since a lot of FPs in MRVA fall into the "unguarded but already-
    initialized" bucket.
