Since strtol(3) doesn't clear errno on success, anything that sets errno prior to this call will make it look like the call failed. This happens when built with ASAN. Signed-off-by: Dan Albert <danalbert@google.com>

When scope_index_read() fails while attempting to allocate memory for scope_index->class_perms_map, scope_index_destroy() gets called with scope->class_perms_len != 0 and scope->class_perms_map == NULL.

When running secilc on the following CIL file, the program tries to free the data associated with type X using cil_destroy_typeattribute(): (macro sys_obj_type ((user ARG1)) (typeattribute X)) (block B (type X) (call sys_obj_type (Y)) ) By adding some printf statements to cil_typeattribute_init(), cil_type_init() and cil_destroy_typeattribute(), the error message I get when using gcc's address sanitizer is: $ secilc -o /dev/null -f /dev/null test.cil -vvvvvv creating TYPE 0x60400000dfd0 Parsing 2017-02-02_crashing_nulptrderef_cil.cil Building AST from Parse Tree creating TYPEATTR 0x60600000e420 creating TYPE 0x60400000df50 Destroying Parse Tree Resolving AST Failed to resolve call statement at 2017-02-02_crashing_nulptrderef_cil.cil:5 Problem at 2017-02-02_crashing_nulptrderef_cil.cil:5 Pass 8 of resolution failed Failed to resolve ast Failed to compile cildb: -2 Destroying TYPEATTR 0x60600000e420, types (nil) name X Destroying TYPEATTR 0x60400000df50, types 0xbebebebe00000000 name X ASAN:DEADLYSIGNAL ================================================================= ==30684==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x7fc0539d114a bp 0x7ffc1fbcb300 sp 0x7ffc1fbcb2f0 T0) #0 0x7fc0539d1149 in ebitmap_destroy /usr/src/selinux/libsepol/src/ebitmap.c:356 #1 0x7fc053b96201 in cil_destroy_typeattribute ../cil/src/cil_build_ast.c:2370 #2 0x7fc053b42ea4 in cil_destroy_data ../cil/src/cil.c:616 #3 0x7fc053c595bf in cil_tree_node_destroy ../cil/src/cil_tree.c:235 #4 0x7fc053c59819 in cil_tree_children_destroy ../cil/src/cil_tree.c:201 #5 0x7fc053c59958 in cil_tree_subtree_destroy ../cil/src/cil_tree.c:172 #6 0x7fc053c59a27 in cil_tree_destroy ../cil/src/cil_tree.c:165 #7 0x7fc053b44fd7 in cil_db_destroy ../cil/src/cil.c:299 #8 0x4026a1 in main /usr/src/selinux/secilc/secilc.c:335 #9 0x7fc0535e5290 in __libc_start_main (/usr/lib/libc.so.6+0x20290) #10 0x403af9 in _start (/usr/src/selinux/DESTDIR/usr/bin/secilc+0x403af9) AddressSanitizer can not provide additional info. SUMMARY: AddressSanitizer: SEGV /usr/src/selinux/libsepol/src/ebitmap.c:356 in ebitmap_destroy ==30684==ABORTING When copying the AST tree in cil_resolve_call1(), __cil_copy_node_helper() calls cil_copy_typeattribute() to grab type X in the symbol table of block B, and creates a node with the data of X but with CIL_TYPEATTRIBUTE flavor. This example is a "type confusion" bug between cil_type and cil_typeattribute structures. It can be generalized to any couple of structures sharing the same symbol table (an easy way of finding other couples is by reading the code of cil_flavor_to_symtab_index()). Fix this issue in a "generic" way in __cil_copy_node_helper(), by verifying that the flavor of the found data is the same as expected and triggering an error when it is not.
