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.
