The future of the Linux Security Module APIThe future of the Linux Security Module APIPosted Apr 20, 2006 13:43 UTC (Thu) by jamesm (guest, #2273)In reply to: The future of the Linux Security Module API by nix Parent article: The future of the Linux Security Module API
This is a misrepresentation of the upstream review process, which will naturally include a challenge as to why a new patch should be accepted into the kernel, particularly if it is duplicating a subset or near-subset of existing code.
No SELinux developer has ever just said "it sucks", but instead would have probably spent a considerable amount of time reviewing the code and then posting a detailed response. It is very often the case that there are serious implementation and design flaws in submissions to the kernel. In the case of LSM in particular, the API has problems which foster the development of modules which are not appropriate as LSMs, and would often be better implemented as distinct kernel components to be called by other LSMs, or simply integrated into what was then the only significant LSM in the tree.

The future of the Linux Security Module API Posted Apr 20, 2006 19:30 UTC (Thu) by hingo (guest, #14792) [Link] So you are saying that according to the upstream review process, you cannot get another LSM user included if it does roughly the same thing as SELinux or a subset of it and also that if SELinux is the only LSM user in the kernel mainline it will be removed... nice logic.(Nothing personal, I just realised that what you described might actually be close to reality.)
The future of the Linux Security Module API Posted Apr 20, 2006 19:41 UTC (Thu) by jamesm (guest, #2273) [Link] No, I am not saying that.
All code being submitted to the mainline kernel needs to be reviewed and justified before acceptance. One of the challenges is to demonstrate why the new code is needed, which reasonably includes asking things like "why partially duplicate something which is already there?"
The future of the Linux Security Module API Posted Apr 20, 2006 20:55 UTC (Thu) by nix (subscriber, #2304) [Link] You're right, that was a misremembering on my part. The SELinux developers didn't say it sucks.
Christoph Hellwig did (actually he called it bullshit).
(Mind you, he seems to be trying for the Al Viro Insult Award, although he seems to have missed the bit in the rulebook that says that the insults have to be *unusual*; insults in obscure dialects or dead languages gain extra credit. The ideal insult is one so obscure that the recipient doesn't have a clue he's been insulted, but clear enough that everyone else on the list knows perfectly well.)
