Modified Files: src/tests/kernel: h_segv.c t_trapsignal.sh Log Message: Extend ATF tests in t_trapsignal.sh to verify software breakpoint traps There are at least four types of SIGTRAP events: - software/hardware single step (trace trap) - software breakpoint - hardware breakpoint/watchpoint - kernel event (exec, fork, vfork, vfork-done, lwp-create, lwp-exit) A program can execute software breakpoint without the context of being traced and this is a regular crash signal emitting SIGTRAP (TRAP_BRKPT). Rename original trap_* tests (trap_simple, trap_handle, trap_mask, trap_handle_recurse and trap_ignore) to segv_* tests and restrict them for SIGSEGV. Add new tests: trap_* testing the same scenarios as segv_ ones, however verifying the software breakpoint trap (SIGTRAP). Keep the original name of h_segv.c, and extend it for software breakpoint events. The purpose of these tests is to verify SIGTRAP kernel paths without the ptrace(2) context. All tests pass.
