* Fix strftime format bugMasami Hiramatsu2009-04-021-3/+6
| | | | | This fixes bugs in strftime-subset function. This modifies %C, %l and %j to fit the output of date command.
* PR9821: staprun supports subset of strftime.Masami Hiramatsu2009-03-201-1/+118
| | | | | Add strftime subset format support for output file name to systemtap. This format will be evaluated when opening a new output file.
* PR6930: stapio: support file switchingMasami Hiramatsu2009-03-201-2/+28
| | | | | | | | | | | | | | | Add file-switching option(-S size[,N]) to stapio. This option has two arguments, 'size' and 'N', and requires -o option. - When the size of output file exceeds specified 'size'MB, staprun switches output file to the next file. For this purpose, all output file has a serial number as a suffix only when user specifies this option. - Using this option in bulk mode, the output file name will be 'FILE_cpuX.SERIAL'. - When the number of files exceeds specified N, staprun removes the oldest file. This argument can be omitted.
* PR6930: stapio: run in background as a daemonMasami Hiramatsu2009-03-201-4/+48
| | | | | | | Add '-D'(daemon mode) option to staprun/stapio for daemon mode. In this mode, stapio shows just its pid and detachs from console. Since it has no stdio, this mode requires -o option. stapio will exit when it receives SIGTERM or detects some error.
* PR6930: staprun: supports error message to syslogMasami Hiramatsu2009-03-201-0/+21
| | | | | Add an interface (eprintf) to output error messages to syslogd, because staprun has no stderr after detaching from console.

Merge from setuid-branch. Changes also by Martin Hunt <hunt@redhat.com>. * staprun.c (init_staprun): Drop CAP_SYS_ADMIN when we're done with it. (main): Calls parse_modpath instead of path_parse_modname. Just call parse_modpath with argv[optind]. Let it allocate and set modpath and modname. If no modulename was given, display usage and exit. Drop CAP_SYS_NICE when we're done with it. Set atexit(exit_cleanup) so cleanup always gets called and modules get removed. Call handle_symbols. (run_stapio): Set argv[0] to stapio so that it executes as itself instead of staprun. (cleanup): Only do cleanups once and only try to remove module when appropriate. (exit_cleanup): New. Calls cleanup(). (mountfs): Sets uid to root before making directory and then restores uid. (setup_ctl_channel): Uses DEBUGFS define and improved error message. (setup_relayfs): Ditto. (setup_oldrelayfs): Uses DEBUGFS and RELAYFS defines. (run_stp_check): Replaced by mountfs(). (mountfs): New function. Replaces an external script with C code. (init_staprun): Calls mountfs() instead of run_stp_check(). * staprun.h: Renamed path_parse_modname to parse_modpath. Added MODULE_NAME_LEN define. Added [_][p]err macros. Removed VERSION_CMD. * mainloop.c (cleanup_and_exit): Make sure initialized is 2 before exiting with code 2. (stp_main_loop): Set initialized to 2 when STP_TRANSPORT is received. Call cleanup_and_exit() with proper status. (start_cmd): exit 1 instead of -1. (system_cmd): Ditto. (init_staprun): Renamed init_stapio. (cleanup_and_exit): Set exit status. * cap.c: New file. * common.c: New file. * stapio.c: New file. * staprun_funcs.c: New file. * Makefile: Removed. * symbols.c (get_sections): Move the filter code up so that uninteresting section names are filtered out before attempting to open them. (do_kernel_symbols): Better detect overfow conditions and realloc new space. (do_module): After sending all modules, send a null message to indicate we are finished. * ctl.c (init_ctl_channel): When attempting to attach, if the control channel doesn't exist, print a better error message. * relay_old.c (init_oldrelayfs): Errors out if open_relayfs_files() couldn't open any files. PR 4795 * mainloop.c (send_request): Fixed buffer overflow check. * staprun.h: Added buffer overflow checking versions of strcpy/sprintf/snprintf. * common.c (path_parse_modname): Checks for overflows on strcpy/sprintf/snprintf. (read_buffer_info): Ditto. * ctl.c (init_ctl_channel): Ditto. * relay.c (init_relayfs): Ditto. * relay_old.c (open_relayfs_files): Ditto. (init_oldrelayfs): Ditto. * staprun_funcs.c (insert_module): Ditto. (check_path): Ditto. * symbols.c (get_sections): Ditto.
