From 5e8a3b7b558273fa06525f642fdf2d678dde85eb Mon Sep 17 00:00:00 2001 From: Dave Brolley Date: Thu, 3 Sep 2009 16:13:30 -0400 Subject: Allow process begin/end probes for unprivileged users. 2009-09-03 Dave Brolley * tapsets.cxx (visit_cast_op): Don't disallow unprivileged users. Annotate synthesized function with /* unprivileged */. * tapset-utrace.cxx (register_tapset_utrace): Call allow_unprivileged for process begin and end probes. * translate.cxx (translate_pass): Generate '#define STP_PRIVILEGED 1' unless --unprivileged was specified. * runtime/transport/transport.c: Don't define _stp_unprivileged_user. * runtime/task_finder.c (__stp_utrace_attach_match_filename): Check that _stp_uid equals the task euid when STP_PRIVILEGED is not defined. (stap_start_task_finder): Likewise. * runtime/staprun/staprun.c (insert_stap_module): Don't generate module option _stp_unprivileged_user. --- runtime/staprun/staprun.c | 10 +--------- 1 file changed, 1 insertion(+), 9 deletions(-) (limited to 'runtime/staprun') diff --git a/runtime/staprun/staprun.c b/runtime/staprun/staprun.c index 7eb7f28f..da3e304b 100644 --- a/runtime/staprun/staprun.c +++ b/runtime/staprun/staprun.c @@ -145,19 +145,11 @@ static int enable_uprobes(void) static int insert_stap_module(void) { char special_options[128]; - char *bufptr = special_options; /* Add the _stp_bufsize option. */ - if (snprintf_chk(bufptr, sizeof (special_options), "_stp_bufsize=%d", buffer_size)) + if (snprintf_chk(special_options, sizeof (special_options), "_stp_bufsize=%d", buffer_size)) return -1; - /* Add the _stp_unprivileged_user option. */ - bufptr += strlen (bufptr); - if (snprintf_chk(bufptr, - sizeof (special_options) - (bufptr - special_options), - " _stp_unprivileged_user=%d", unprivileged_user)) - return -1; - return insert_module(modpath, special_options, modoptions); } -- cgit
