Dear Beowulfers, There's no doubt everybody is well aware of CVE-2016-5195 by now, and that all your systems have been patched several days ago. I mean, all the systems that run a supported LTS distribution.
Because, in case you're like me, you may have to maintain some clusters at specific point releases, and you can't really update everything to the latest LTS version (because of, I don't know, vendors that provide pre-compiled kernel modules, for instance). If you're running a Red Hat based distribution such as CentOS, you probably now that: 1. the upstream fix doesn't apply on your kernel 2. the only supported release is the latest one, meaning that if you have to stay on say CentOS 6.7 for whatever reason, you don't get a kernel with the Dirty COW fix. And that is obviously a problem. So, in case it could help someone, I put together some instructions on how to apply the fix on your RHEL 6.x kernels (works from 6.5 to 6.8). Enjoy! https://github.com/stanford-rc/RHEL6.x-COW Cheers -- Kilian _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
