[LU-1361] Lustre kernel rpm does not provide kernel ABI (kabi) information

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.3.0, Lustre 2.1.2
• Affects Version/s: Lustre 2.1.0
• Environment: RHEL/CentOS 6.2
• Severity: 3
• Assignee: Minh Diep
• Reporter: Greg Edwards

Description

It appears the Lustre kernel rpm is built without any of the kernel ABI (kabi) information
left in tact. For example:

[root@localhost ~]# rpm -q --provides kernel-2.6.32-220.el6_lustre.g4554b65.x86_64
kernel = 2.6.32-220.el6_lustre.g4554b65
kernel-x86_64 = 2.6.32-220.el6_lustre.g4554b65
kernel-drm = 4.3.0
kernel-drm-nouveau = 16
kernel-modeset = 1
kernel-uname-r = 2.6.32-220.el6_lustre.g4554b65.x86_64
kernel-xen = 2.6.32-220.el6_lustre.g4554b65
kernel = 2.6.32-220.el6_lustre.g4554b65
kernel(x86-64) = 2.6.32-220.el6_lustre.g4554b65

Compare this with the corresponding kernel rpm from RHEL/CentOS:

$ rpm -q --provides kernel-2.6.32-220.el6.x86_64
kernel = 2.6.32-220.el6

kernel-drm-nouveau = 16

.... and so forth ....

Note your kernel is missing all the kabi hashes for the whitelisted
(exported) symbols.

This causes problems when installing other kernel modules that are
packaged according to Red Hat's kernel module package format. See:
