Hello all,
I am testing some former programs with xenomai-2.4-rc4/kernel-2.6.23.1/pentiumM;
Calling rt_task_inquire(Id, NULL) with a null second argument now
freezes or reboots the pc...
I had no problem with this call with a former (2.3.1) xenomai version. Is it a
known behaviour?
Daniel

the rt_task_inquire system call checks that the "info" pointer points to
a piece of writable memory and returns -EFAULT otherwise. So, what you
should get is a segmentation fault, no freeze or reboot. Actually, I
have tested a small test which segfaults as expected. Could you provide
us with the simple test that causes a freeze or reboot ?

That was the behaviour I got with xenomai-2.3.1 (I only wanted to check if the
task was still existing and thus only interested in the value returned)

file testinfo.c and config attached, uncommenting line 201 reboots the system
at cleaning time after ^C
(xeno 2.4-rc5, kernel 2.6.23.1, gcc 4.0.2 with --xeno-cflags and --xeno-ldflags)

As a matter of fact, the address checking code on x86* considers any
address below the page offset as being valid, so passing NULL went
undetected in your case. This was already the case with 2.3.1, you
likely just got lucky with respect to the consequences of another hole -
in the I-pipe this time - which has been plugged recently, and now fixes
up any fault whenever Xenomai has to leave it unhandled:
http://www.denx.de/cgi-bin/gitweb.cgi?p=ipipe-2.6.git;a=commit;h=e7b140c69794521fe8979a39337f36112dbe330c
The fix above was only available when CONFIG_IPIPE_DEBUG was enabled in
the latest patch series, and prevented any ungraceful consequence of
writing to an invalid address from the Xenomai domain. We actually need
to have this fixup done in any case. Next I-pipe patches will include
this change.
In short, rt_task_inquire() has never been meant to accept a NULL
parameter so far, and doing so was not properly caught at Xenomai level.
When using the invalid pointer that went undetected for writing the
output data back, some I-pipe issue let the resulting access fault
unhandled, causing a general panic state in the kernel whenever the
fixup above was not active (older I-pipe support or CONFIG_IPIPE_DEBUG
disabled).
I've slightly improved the address checking code for x86 32/64, so that
it also detects any address lower than the natural page size, which
would have caught the NULL case. We can't do much more, at least on the
fast path, than detecting addresses lower than PAGE_SIZE or located in
kernel memory. Other spurious addresses should trigger a segmentation
violation, which should be properly handled in all cases using an I-pipe
/x86 patch beyond 1.10-11 (the same goes for x86_64, beyond 1.2-05).
Now, it seems reasonable to ask rt_task_inquire() to test whether the
target task exists or not, in which case it may be acceptable to pass a
NULL buffer. This change will likely be applied to the trunk asap, and
will be part of -rc6.

Could you explain why Xenomai is special here? The range-checking macros
matched mainline before (as it should be), now it is different without
any (at least to) obvious reason. Their purpose is not to avoid page
faults but to avoid "confused deputy" attacks (user making the kernel
accessing privileged memory).

I'm not sure if we need this debugging feature on by default - in the
fast path of Linux code running on usual page faults. The check must
never fire unless the RT domain's kernel is buggy, thus we should only
use it during debugging.
Something is fishy here - or I'm still missing the point. The question
for me is: Why was the NULL pointer access over Xenomai passed through
without relaxing the caller, which then causes all those lethal
corruptions? Were you able to reproduce this case and understand what
goes wrong, Philippe?

Sorry, makes no sense to me. If the user makes us accessing the NULL
page, we receive a nice trap, relax the thread, and ideally report the
bug as EFAULT back to the user, no?

Mainline macros only check for (addr < PAGE_OFFSET), which basically
says that any address below the first kernel location is ok. The rest is
expected to be caught by the usual exception mechanism. Because of the
dual domain model, we have to fixup things that Linux hasn't.

You are missing the major issue: there is some situations where Xenomai
will never handle a fault occurring on top of the Xenomai domain,
because it has not really be triggered by a shadow, but rather by a pure
Linux thread running a syscall in high stage. This is the case for those
running __xn_exec_any flagged services, like rt_task_inquire. And no, we
don't want to turn __xn_exec_any services into __xn_exec_conforming
ones, because there is no point in having real-time threads calling such
services from secondary mode to be uselessly switched to primary mode.

As explained, some situations should better be left to the I-pipe as a
fallback situation. This is what is going to happen with the next patches.
What we have to do is the fixup always, only enabling the debug message
and the trace freeze according to the IPIPE_DEBUG knob. The rationale is
simple: those situations are bugous, but should not be lethal, because
Linux normally allows for the fault to occur, so we should allow this
too. But since this reveals a problem, this has to be reported in the
message log when running in debug mode, since we cannot propagate this
information in any other way.

The caller was _NOT_ running as a shadow. You may have tasks running as
pure Linux threads in the Xenomai domain. In such a case, Xenomai
_cannot_ handle the situation by itself, and needs the help of the
I-pipe, because only the I-pipe is allowed to switch domains.

What things precisely? Maybe just a clarifying comment is lacking in the
code, though for me this patch still looks unrelated to the issue below.

OK, got it. We do have a case now where faults happen over non-root
domains and are not a kernel faults. But such faults, even though they
are not OK, shall not uselessly flood our kernel console. Instead, we
need to switch silently and let Linux handle them. If the faults are
fixable (like in this case), we are fine again. If not, we see the usual
oops. Maybe we can track - silently - if there was a switch back earlier
in order to report the original domain in the oops.

Ack. Still, this fiddling with __xn_access_ok is totally unclear to me.
