Adds stap_kprobe_process_found and stap_kprobe_mmap_found handlers and then the task_finder uses those to set the semaphore values. The probe adds user_path and user_lib which are used by the task_finder to decide what object to sniff. * sdt.h (STAP_SEMAPHORE): Also define for kprobes. * tapsets.cxx (dwarf_derived_probe): Add user_path and user_lib. (dwarf_derived_probe::join_group): Enable task finder for kprobes. (dwarf_derived_probe::dwarf_derived_probe): Set user_path and user_lib. (dwarf_derived_probe_group::emit_module_decls): Emit stap_kprobe_mmap_found, sdt_sem_offset, sdt_sem_address, pathname, and finder declarations. Emit stap_kprobe_process_found and stap_kprobe_mmap_found. (dwarf_derived_probe_group::emit_module_init): Setup task finder. (sdt_query::convert_location): Remove TOK_LIBRARY token. (dwarf_builder::build): Set user_path and user_lib. (kprobe_derived_probe): Add path and library. (kprobe_builder::build): Get process and library params ----------------------------------------------------------------------- Summary of changes: includes/sys/sdt.h | 10 +- tapsets.cxx | 213 +++++++++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 198 insertions(+), 25 deletions(-) hooks/post-receive -- systemtap: system-wide probe/trace tool
