Description Eugene Teo (Security Response) 2007-05-18 04:33:08 UTC
Description of problem:
The linux/nfs_mount.h header file from glibc-kernheaders-2.4-9.1.100.EL rpm does
not tally with the linux/nfs_mount.h header file from kernel-2.6.9-55.EL rpm. As
a result, the am-utils-6.0.9-15.RHEL4 rpm that is built against an older version
of linux/nfs_mount.h, will trigger a lot of warning messages "kernel: nfs
warning: mount version older than kernel" in the logs.

[root@padme linux]# pwd
/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/include/linux
[root@padme linux]# grep -r NFS_MOUNT_VERSION .
./nfs_mount.h:#define NFS_MOUNT_VERSION 6
[root@padme include]# pwd
/usr/include
[root@padme include]# grep NFS_MOUNT_VERSION ./linux/nfs_mount.h
#define NFS_MOUNT_VERSION       4

Version-Release number of selected component (if applicable):
glibc-kernheaders-2.4-9.1.100.EL
am-utils-6.0.9-15.RHEL4
kernel-2.6.9-55.EL

How reproducible:
Always.

Steps to Reproduce:
1. Install am-utils
2. tail -f /var/log/messages &
3. service amd start

You will be able to see the warning messages.

Actual results:
"kernel: nfs warning: mount version older than kernel" messages appeared in logs.

Expected results:
"kernel: nfs warning: mount version older than kernel" messages should not
appear in logs.

Additional info:
By using the kernel headers from a more recent kernel, and rebuilding the amd
RPM would help resolve this problem.
