Description Keiichiro Tokunaga 2007-09-07 14:08:11 EDT
We found a problem concerning kabi_whitelist when we trid to make a test 
module of MCA handler.

[root@RHEL5-ss3 TMP5.1]# /usr/bin/python ./abi_check.py
Red Hat Enterprise Linux 5.0 ABI

Kernel: 2.6.18-41.el5
Whitelist: /usr/src/kernels/2.6.18-41.el5-ia64/kabi_whitelist

WARNING: The following symbols are used by your module
WARNING: and are not on the ABI whitelist.

symbol: ia64_mca_printk
symbol: ia64_mlogbuf_dump

Both ia64_mca_printk and ia64_mlogbuf_dump are introduced by the patch here, 
which are exported for use by a platform-specific MCA handler (which 
registered via ia64_reg_MCA_extension), but are not on the whitelist.

So this couple of symbols needs to be added to the whitelist, ex. the 
following changes are required:

+       ia64_mca_printk
+       ia64_mlogbuf_dump
Comment 1 Keiichiro Tokunaga 2007-09-07 16:15:19 EDT
A patch posted to rhkernel-list today.
Comment 2 Keiichiro Tokunaga 2007-09-26 11:43:44 EDT
Moving to 5.2.
Comment 9 Jon Masters 2008-03-27 12:42:51 EDT
Can we confirm this is in RHEL5.2. Kei, are you happy? I can see this in the CVS
head at the moment, but let's make sure it's cool with you before closing.

Comment 10 Jon Masters 2008-03-27 13:11:49 EDT
Don, can you set this MODIFIED if you're happy with it?
Comment 11 Don Zickus 2008-03-27 13:35:41 EDT
in kernel-2.6.18-73.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5
Comment 12 Keiichiro Tokunaga 2008-03-27 14:31:53 EDT
I have confirmed the symbols are in the recent whitelist (ia64) and I am OK with
either closing this bug or setting it VERIFIED.
