Product: Base System Version: 13.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: wzis@hotmail.com the procctl for PROC_TRACE_CTL is not working on my FreeBSD 13.1. [root@bsd123 ~]# uname -a FreeBSD bsd123 13.1-RELEASE-p9 FreeBSD 13.1-RELEASE-p9 GENERIC amd64 [root@bsd123 ~]# cat dt.c #include <stdlib.h> #include <sys/types.h> #include <sys/procctl.h> #include <unistd.h> #include <stdio.h> int main(int argc, char *argv[]) { int trace_flag =3D PROC_TRACE_CTL_DISABLE; pid_t pid; if (argc !=3D 2) { printf("Usage: %s <pid>\n", argv[0]); return 1; } pid =3D atoi(argv[1]); if (procctl(P_PID, pid, PROC_TRACE_CTL, &trace_flag) =3D=3D -1) { perror("procctl"); return 1; } printf("Tracing disabled for process %d\n", pid); return 0; } [root@bsd123 ~]# cc -o dt dt.c [root@bsd123 ~]# ./dt 868 Tracing disabled for process 868 [root@bsd123 ~]# truss -p 868 As above showing, though the procctl didn't error out, but after "disable" = the tracing, the "truss -p PID" still can attach to the process. --=20 You are receiving this mail because: You are the assignee for the bug.=
