https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261999 Bug ID: 261999 Summary: [dtruss] dtrace: invalid probe specifier => lstat* not found Product: Base System Version: 12.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: joerg@FreeBSD.org Plain dtruss(1) on FreeBSD 12.3-stable gives: # dtruss ls dtrace: invalid probe specifier #pragma D option quiet #pragma D option switchrate=10 /* * Command line arguments */ inline int OPT_command = 1; inline int OPT_follow = 0; inline int OPT_printid = 0; inline int OPT_relative = 0; inline int OPT_elapsed = 0; inline int OPT_cpu = 0; inline int OPT_counts = 0; inline int OPT_pid = 0; inline int OPT_name = 0; inline int OPT_trace = 0; inline int OPT_stack = 0; inline string NAME = "."; inline string TRACE = "."; … /* print 3 args, arg0 as a string */ syscall::access*:return, syscall::stat*:return, syscall::lstat*:return, syscall::readlink*:return, syscall::open*:return /self->start/ { … When I run it with DTRACE_DEBUG, I see … libdtrace DEBUG: set context to syscall::access*:return [0] prp=0x0 attr=[u/u/c] argc=0 libdtrace DEBUG: set label to <action list> libdtrace DEBUG: set label to <NULL> libdtrace DEBUG: set label to <predicate> libdtrace DEBUG: set label to <NULL> libdtrace DEBUG: set context to syscall::stat*:return [0] prp=0x0 attr=[u/u/c] argc=0 libdtrace DEBUG: set label to <action list> libdtrace DEBUG: set label to <NULL> libdtrace DEBUG: set label to <predicate> libdtrace DEBUG: set label to <NULL> dtrace: invalid probe specifier … So apparently, the last correctly parsed probe specifier is "syscall::stat*:return", then it bails out. Removing the "syscall::lstat*:return," line makes it work. Note sure why that probe is missing though. -- You are receiving this mail because: You are the assignee for the bug.
