Description of problem: Version-Release number of selected component (if applicable): kernel-2.6.18-232.el5 kernel-devel-2.6.18-232.el5 kernel-headers-2.6.18-232.el5 samba-3.0.33-3.29.el5_5.1 samba-client-3.0.33-3.29.el5_5.1 samba-common-3.0.33-3.29.el5_5.1 How reproducible: always Steps to Reproduce: run following test on ia64 machine /CoreOS/selinux-policy/Regression/bz484146-smbd-and-spamassassin-in-user-home-dir Actual results: kernel unaligned access to 0xe000000135af2147, ip=0xa0000002117dd0f1 kernel unaligned access to 0xe00000409b155837, ip=0xa000000100247b50 kernel unaligned access to 0xe00000409b15583f, ip=0xa000000100247b50 kernel unaligned access to 0xe00000409b155847, ip=0xa000000100247b50 kernel unaligned access to 0xe00000409b15584f, ip=0xa000000100247b50 Expected results: no "unaligned access" messages
It's necessary to be logged in via console when running the test.
Created attachment 467618 [details] stack dump from each unaligned access This does not appear to be an SELinux issue at all. It appears the relevant functions are: smbCalcSize_LE and utf8_mbtowc
This is clearly a cifs issue, and not an ia64 issue. I'll find out who owns cifs and reassign the BZ to them. P.
Sounds like this may be similar to this bug report. I'll have to re-familiarize myself with it... https://bugzilla.kernel.org/show_bug.cgi?id=11115
Milos, I have a backported patchset of the one that should be going upstream in my test kernels here: http://people.redhat.com/jlayton/ ...could you test these and let me know if they solve the issue for you?
"unaligned access" messages disappeared. Following packages were installed before the test: kernel-devel-2.6.18-240.el5.jtltest.129 kernel-2.6.18-240.el5.jtltest.129
