Hi Roland, hi everybody,
I have finished teaching my spring term so I am back working on utrace.
I am porting my stuff about virtualquare kmview on the new version of
kernels.
I ran into something that seems to be a bug on PTRACE_SINGLEBLOCK.
The source code here enclosed says OKAY on a

has the tracing of system calls changed in utrace between Fedora 8 and 9?
For some reason the only way to trace the syscall is to trace also
UTRACE_EVENT(SIGNAL_TERM)
or CORE.
I added an empty report_signal function and now

This may not answer your question, but I believe it is not proper to

Maybe I am wrong but the quiesce callback gets called *before* the other

Dear Roland, dear utrace developers,
I have update also the second patch (which includes the first).
This patch fixes the utrace_stop race condition and

I have updated my patch #1 (it solves the race condition on utrace_stop but

I am trying to get the patches updated downloading, compiling and testing
the fixes every week or so...
Things would be

Hi Ronald utrace developers
I am back...
I am upgrading my kmview support and I have stepped into a clear bug.
in utrace_reap:
--
list_for_each_entry_safe(engine, next, utrace-attached, entry) {
ops = engine-ops;
engine-ops = NULL;
engine-flags = 0;
Let me add my two euro-cents to this discussion.

Unfortunately ptrace does all that magic already (badly). People don't
just use it for (s)tracing syscalls, but also for tracing signals, for
single step debugging and poking at memory, register state, for process

I ran the whole systemtap testsuite with a kernel built from your git
tree, and did not see any utrace-specific issues. Thanks!
I have got the git tree, too.
