* libsandbox: add pre checks to static tracingMike Frysinger2009-06-041-31/+7
| | | | | | | | | | The normal wrapped functions go through some "pre checks" where certain normal conditions are not flagged as problematic. The static tracing lacked those pre checks though.

* libsandbox: add debug output for all wrapper early-checksMike Frysinger2009-03-121-1/+5
| | | | | | | | If a wrapped function bails early due to some local logic, make sure we log this at the debug level. Having them silently return on us makes tracking down problems harder than it needs to be. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* libsandbox: push errno save/restore down in openat()Mike Frysinger2009-03-071-5/+5
| | | | | | | Minor optimization to not bother saving/restoring the errno if we don't actually call another C library function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* libsandbox: add wrappers for _FORTIFY_SOURCE funcsv1.3.8Mike Frysinger2009-02-201-0/+44
When glibc is compiled with optimization and higher _FORTIFY_SOURCE levels, the headers redirect dynamic calls to the open*() functions to the __open*_2() functions. The latter provides runtime checking. But this means we also need to wrap the latter forms in order to get sandbox checking on the open() functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
