commit c0456b6fda16307070e0896d3cca86f523214a5e
Author: David Smith <dsmith@redhat.com>
Date: Fri Mar 23 15:52:01 2012 -0500
Improve build-id checking when the task we're interested in isn't 'current'.
* translate.cxx (emit_module_init): Moved include files to
runtime/runtime.h.
* runtime/runtime.h: Moved includes here from translate.cxx. Rearranged
order a bit, to allow use of __access_process_vm() earlier.
* runtime/sym.c (_stp_build_id_check): Instead of passing in a flag to
indicate build-id checking a user module, instead pass a task_struct
pointer in. If the task_struct pointer isn't 'current', use
__access_process_vm() to read data.
(_stp_module_check): Update _stp_build_id_check() call.
(_stp_kmodule_check): Ditto.
(_stp_usermodule_check): Ditto.
* runtime/vma.c (_stp_vma_match_vdso): If the task we're trying to match
isn't 'current', use __access_process_vm() to read data.
