Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
Customer get's this message:
Sep 17 13:50:48 localhost kernel: Spectre V2 : WARNING: module 'oracleasm' built without retpoline-enabled compiler, may affect Spectre v2 mitigation
Version-Release number of selected component (if applicable):
kmod-oracleasm-2.0.8-15.el6_9.x86_64
How reproducible:
Install the above module on a retpoline installed kernel
Some notes on previous kmod-oracleasm updates:
Some customers require the Oracle ASMlib kernel module ("oracleasm"). Oracle has indicated that, although they provide this module for earlier RHEL releases, they will not do this for RHEL 6.
The module is open source, and available in several locations on the Internet. We plan to ship it as a kmod, separate from the kernel package, in the Supplementary channel. This is done to make it clear that Red Hat provides only limited support. x86_64 only.
The kernel module uses some symbols that are not on the whitelist. As a result, it will be advisable to re-build the module for each y-stream release, and then manually check to ensure that there are no relevant kernel symbol changes during the z-stream.
The ASMlib kmod rpm package will be marked as dependent on the y-stream GA kernel version (and any subsequent z-stream kernels). This will ensure that either both the kernel and ASMlib module are upgraded, or both are not upgraded, or the kernel is upgraded and asmlib uninstalled.
