Description Roland McGrath 2005-06-08 09:26:41 UTC 
In the RHEL3 kernel on x86_64, PTRACE_SETOPTIONS only supports the
PTRACE_O_TRACESYSGOOD flag, not the others.  The generic code would be fine if
it were used.  The arch/x86_64/kernel/ptrace.c code just needs not to override
it for that case.

Patch posted for review on 8-Jun-2005.
Comment 4 Ernie Petrides 2005-06-15 01:02:30 UTC 
A fix for this problem has just been committed to the RHEL3 U6
patch pool this evening (in kernel version 2.4.21-32.8.EL).

test case

There is no real-world test case because I punted using the features that were
broken in the kernel.  I've whipped up this simple contrived test case.

Steffen, that Issue Tracker report has nothing to do with this bug.

Please unlink BZ 159814 from IT 53971.
