[LU-1354] PGP Sign RPM's

• Type: New Feature
• Resolution: Unresolved
• Priority: Minor
• Affects Version/s: Lustre 2.7.0, Lustre 2.5.5

Description

The current RHEL RPM's as delievered by whamcould are not signed with a PKI certificate. It would be beneficial if Whamcloud could sign the RPM's with PKI to verify that Whamcloud is in fact the author of the RPM's.

Bumping this topic. Any news?

Is there any news on this topic ?

After further investigation. The module signing / cert management is as follows:

1. During the kernel build, a unique pub/priv key is generated (using info in kernelsource/x509.genkey):

   kernelsource/signing_key.{x509,priv}
   

1. All certificates in kernel source dir (files with the .x509 extension) are signed with the per-kernel key and included in the default trust chain.
2. All kernel modules are signed with the signing_key and thus any module signed with those would also be acceptable.

NOTE:
CentOS does not sign any of the provided kmod-* packaged modules.

If we're going to sign rpms, we should also consider signing the modules so they will work in a FIPS enabled kernel.

It would be valuable to have the RPMS finally signed - also in order to use them properly with configuration management tools like Puppet, etc.

There are several people (myself, Brian Murrell, maybe Oleg) on the HPDD team that have well-known keys that could sign an RPM-signing key.

[Michael Di Domenico]

Well some trust is better then no trust, eh? But it does provide someone an ability to verify that the packages were created by a specific person and that the packages have not been altered down the chain.

as long as the passphrase is safe and the whamcloud servers remain protected, I should be able to sign-off to an auditor that the software I downloaded did in fact come from and was produced by Whamcloud. The only other way I can make that claim with any real distinction would be to have a (silver, non-r/w) CD mailed from whamcloud to me.

We certainly could create a GPG key and sign our RPMs with it. It would be a key with likely no web of trust to it from you though so how much would you really trust it?
