8 years agodfa: fix some unlikely integer overflows
Paul Eggert [Wed, 14 Dec 2016 21:21:04 +0000 (13:21 -0800)]
dfa: fix some unlikely integer overflows

I found these while reviewing the recent Coverity-related fix.
This patch changes part of dfa.c to prefer ptrdiff_t instead of
size_t for object counts.  Using ptrdiff_t is the style typically
used in Emacs; although it wastes a sign bit as sizes can never be
negative, it makes -fsanitize=undefined more likely to catch
integer overflows in index calculation, and nowadays the upside is
typically more important than the downside.  Although perhaps the
rest of dfa.c should be changed to prefer ptrdiff_t as well (much
of dfa.c already does, since it uses state_num which is signed),
that is a bigger change and is not needed to fix the bugs I found.
* lib/dfa.c: Include stdint.h and intprops.h.
(TOKEN_MAX): New macro.
(position_set, struct mb_char_classes, struct dfa, maybe_realloc)
(charclass_index, parse_bracket_exp, addtok, insert, merge)
(realloc_trans_if_necessary, free_mbdata):
Use ptrdiff_t instead of size_t for object counts related to xpalloc.
This is safe because xpalloc checks that the sizes do not exceed
either SIZE_MAX or PTRDIFF_MAX.
(xpalloc): New function, mostly taken from Emacs.
(maybe_realloc, copy, realloc_trans_if_necessary): Use it.
(maybe_realloc): Add NITEMS_MAX to signature.  All callers changed.
(charclass_index): Check for integer overflow in computing
charclass index; it must not exceed TOKEN_MAX - CSET, as CSET is
added to it later.
(alloc_position_set): Check for integer overflow.  On typical
platforms this check has zero overhead, since the constant
expression is false.
(realloc_trans_if_necessary):
Remove assertion, which I hope Coverity no longer needs.
* modules/dfa (Depends-on): Add intprops, stdint.

strerror_r-posix: Fix override of AC_FUNC_STRERROR_R

Requiring autoconf's AC_FUNC_STRERROR_R and then calling AC_DEFINE
ourselves leads to two insertions of #define STRERROR_R_CHAR_P
in confdefs.h, but with different values (at least on glibc).  This
in turn sparks a gcc warning about redeclaring the macro, and kills
any subsequent tests that use -Werror (which now error because of
the conflicting define, whether or not the test used to error).

A better approach is to replace the autoconf macro with a version
of our own that doesn't probe anything, so that the AC_DEFINE is
reached exactly once.

* m4/strerror_r.m4 (AC_FUNC_STRERROR_R): New override.
(gl_FUNC_STRERROR_R): Don't reuse AC_DEFINE() with a potentially
different value.
