Josh Poimboeuf 687e2caabc create-diff-object: Don't strip callback section symbols ... Internal CI is reporting a SIGSEGV in create-diff-object when it processes macro-callbacks.patch, starting with 19baa5b7c7 ("create-diff-object: process debug sections last"). The problem is that, after changing the order between callback and debug section inclusion, kpatch_include_debug_sections() now tries to include the callback section symbols. But kpatch_include_callback_elements() inadvertently un-includes the callback section symbols (e.g., ".kpatch.callbacks.pre_patch") when it un-includes the callback struct symbols (e.g., "kpatch_pre_patch_data"). So after kpatch_elf_teardown(kelf_patched), the callback section symbols get freed even though there are DWARF .debug_info relocations which reference them. Then kpatch_check_relocations() goes off into the weeds when it accesses one of the freed symbols. Fix it by refining the callback un-include logic so that it *only* strips the struct object symbols. Fixes: 19baa5b7c7 ("create-diff-object: process debug sections last") Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com>		2020-02-18 10:16:39 -06:00
