* libdw: Fix crashing on illegal/zero Dwarf_Die.Mark Wielaard2018-05-151-2/+3
| | | | | | | | | | | In some cases we create an illegal Dwarf_Die by clearing all fields. The idea is that dwarf_tag () on such a Dwarf_Die will return DW_TAG_invalid, to indicate that the Dwarf_Die is unusable (and other functions will also return errors). But when "reconstructing" the Dwarf_Die addr we might use the cu before realizing the Dwarf_Die is invalid. Fix this with an explicit NULL check and add a testcase.

* Remove old-style function definitions.Mark Wielaard2015-09-231-3/+1
| | | | | | | We already require -std=gnu99 and old-style function definitions might hide some compiler warnings. Signed-off-by: Mark Wielaard <[email protected]>
* Remove redundant NULL tests.Chih-Hung Hsieh2015-09-141-2/+1
| | | | | | | | GCC6 and Clang give warnings on redundant NULL tests of parameters that are declared with __nonnull_attribute__. Signed-off-by: Chih-Hung Hsieh <[email protected]> Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Check DW_AT_sibling attribute offset is after current DIE.Mark Wielaard2015-01-151-2/+5
| | | | | | | | | | The sibling attribute should point after this DIE in the CU. Otherwise various algorithms might loop or go into infinite recursion walking the DIE tree. Found by afl-fuzz. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Check sibling attribute offset still falls inside CU data.Mark Wielaard2015-01-121-0/+7
| | | | | | Found with afl-fuzz. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: save startp/endp boundaries in Dwarf_CUJosh Stone2014-12-111-4/+2
| | | | | | | Rather than looking up section data every time, we can simply save the range of each CU as pointers in Dwarf_CU. Signed-off-by: Josh Stone <[email protected]>
* libdw: Always check __libdw_find_attr return value.Mark Wielaard2014-11-261-2/+2
| | | | | | | __libdw_find_attr will return NULL and might not set code or form. Only use code or form if the returned address is not NULL. Signed-off-by: Mark Wielaard <[email protected]>
