From: dsmith@sourceware.org To: systemtap-cvs@sourceware.org Subject: src/runtime/staprun ChangeLog ctl.c mainloop.c ... Date: Tue, 14 Aug 2007 15:24:00 -0000 [thread overview] Message-ID: <20070814152359.19927.qmail@sourceware.org> (raw) CVSROOT: /cvs/systemtap Module name: src Changes by: dsmith@sourceware.org 2007-08-14 15:23:59 Modified files: runtime/staprun: ChangeLog ctl.c mainloop.c relay.c relay_old.c staprun.c staprun.h symbols.c Added files: runtime/staprun: cap.c common.c stapio.c staprun_funcs.c Log message: 2007-08-14 David Smith <dsmith@redhat.com> 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.
