Rodriguez" <mcgrof@...e.com>, netfilter-devel@...r.kernel.org Subject: Looking for extensible kernel database format Hey folks, next week I'd like to address replacing the need for CRDA [0] as a udev helper with in-kernel functionality There's a few motivations for this but a good one is that the kernel already has now cryptographic support to verify the integrity of the regulatory database, just as it has support for verifying the integrity of modules / firmware. We'd use something like: request_file(file_reqs) Where the file_reqs provides the requirements, including cryptographic requirements, and I suspect we'd use LSM to vet for the cryptographic needs of the file. Now other than this step CRDA currently *reads* a database and today we have our own format. If we want to extend this though we will have to issue a new regdb format and old kernels might not be compatible with the new format. This is a typical database problem and I'm hoping we are not the first to deal with this. What *extensible* kernel database format are there already, are they generic already? I'd prefer something already using netlink. Any recommendations?
