Dmesg prints the module name when a stap module is loaded. However, neither systemtap.sum nor systemtap.log record the stap module name for every stap run, so it's not easy to tell which testcase caused a particular warning. This can be fixed by having the runtime print the original name of the script file to dmesg. The eBPF backend should also do this. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread

However, typically the full path to the stap script file is printed. It would probably be good to trim directories from the stap file path. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread

For every bpf program loaded into the kernel, stapbpf outputs a corresponding notice to dmesg(), mirroring _stp_print_kernel_info in the default backend. This required defining a new ELF section 'stapbpf_script_name' in the .bo files output by bpf-translate.cxx. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
