[tor/release-0.2.2] Detect and handle NULL returns from (gm/local)time_r
by nickm＠torproject.org 29 Apr '11

29 Apr '11

commit 51e551d3837990b7c4491253a88bedd2513fe1de Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue Dec 7 14:37:50 2010 -0500 Detect and handle NULL returns from (gm/local)time_r These functions can return NULL for otherwise-valid values of time_t. Notably, the glibc gmtime manpage says it can return NULL if the year if greater than INT_MAX, and the windows MSDN gmtime page says it can return NULL for negative time_t values. Also, our formatting code is not guaranteed to correctly handle years after 9999 CE. This patch tries to correct this by detecting NULL values from gmtime/localtime_r, and trying to clip them to a reasonable end of the scale. If they are in the middle of the scale, we call it a downright error. Arguably, it's a bug to get out-of-bounds dates like this to begin with. But we've had bugs of this kind in the past, and warning when we see a bug is much kinder than doing a NULL-pointer dereference. Boboper found this one too. --- changes/gmtime_null | 6 +++ src/common/compat.c | 104 +++++++++++++++++++++++++++++++++++++++++++++------ src/common/compat.h | 9 ---- 3 files changed, 98 insertions(+), 21 deletions(-) diff --git a/changes/gmtime_null b/changes/gmtime_null new file mode 100644 index 0000000..16a2540 --- /dev/null +++ b/changes/gmtime_null @@ -0,0 +1,6 @@ + o Minor bugfixes + - On some platforms, gmtime and localtime can return NULL under + certain circumstances even for well-defined values of time_t. + Try to detect and make up for this deficiency.
