Description Roland McGrath 2007-03-22 20:49:44 EDT
+++ This bug was initially created as a clone of Bug #232837 +++

The frysk test suite now has a good regression test for this issue, which I've
fixed in the Fedora kernel.  The behavior is a regression from RHEL4 and all
prior kernels.
Comment 1 RHEL Product and Program Management 2007-03-22 21:06:08 EDT
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.
Comment 4 RHEL Product and Program Management 2007-06-20 08:31:34 EDT
This request was evaluated by Red Hat Kernel Team for inclusion in a Red
Hat Enterprise Linux maintenance release, and has moved to bugzilla 
status POST.
Comment 5 Don Zickus 2007-07-19 16:06:35 EDT
in kernel-2.6.18-30.el5
Comment 7 Mike Gahagan 2007-08-28 15:47:33 EDT
Which testcase should be used to verify this bug? This is the only difference
I'm seeing in running the test suite that comes with frysk. Is the stopkills
test case the one I should be looking at for this bug?

[root@test183 tests]# diff out.2.6.18-*
18c18
< PASS: frysk4330/stopkills
---
> FAIL: frysk4330/stopkills
[root@test183 tests]# echo diff out.2.6.18-*
diff out.2.6.18-43.el5 out.2.6.18-8.el5

the failure mode according to strace is the ptrace(PTRACE_DETACH,...) call is
failing with a -ESRCH (No such process), but I'm not sure if that applies here.
Comment 8 Mike Gahagan 2007-08-28 16:30:13 EDT
nevermind... looks like the testcase I mentioned in comment 7 is for bz235545
which is also fixed. :). I found the testcase in Bug #232837 and I can confirm
it is fixed with the -43 kernel.
