teor	879b39e1a8	Further unit test tor_timegm and parse_rfc1123_time ... Add unit tests for tor_timegm signed overflow, tor_timegm and parse_rfc1123_time validity checks, and correct_tm year clamping. Unit tests (visible) fixes in bug 13476.	2014-10-20 02:52:21 +11:00
teor	d7b13543e2	Clamp (some) years supplied by the system to 1 CE ... Clamp year values returned by system localtime(_r) and gmtime(_r) to year 1. This ensures tor can read any values it might write out. Fixes bug 13476.	2014-10-20 02:47:31 +11:00
teor	238b8eaa60	Improve date validation in HTTP headers ... Check all date/time values passed to tor_timegm and parse_rfc1123_time for validity, taking leap years into account. Improves HTTP header validation. Avoid unlikely signed integer overflow in tor_timegm on systems with 32-bit time_t. Fixes bug 13476.	2014-10-20 02:40:27 +11:00
teor	dd556fb1e6	Use correct day of year in correct_tm() ... Set the correct day of year value in correct_tm() when the system's localtime(_r) or gmtime(_r) functions fail to set struct tm. Fixes bug 13476.	2014-10-20 02:32:05 +11:00
