You should first do the changes that make the old name obsolete and only after that have a patch that does the rename. Unfortunately, this patch cannot possibly acked with the current order. /Jarkko

If the rename happens afterwards, now two patches will always need to be reverted instead of the possibility of one. Is this your expectation?

Is this your expectation? I'd drop this patch altogether. Old name is a bit ugly but does it matter all that much? You already 16 patches without this. /Jarkko

Is this your expectation? If the keyring name change is independent of any other changes, as Jarkko suggested, nothing would break. > I'd drop this patch altogether.

The name "get_builtin_and_secondary_restriction" implies trust based on keys in the ".builtin_trusted_keys" and ".secondary_trusted_keys" keyrings. This patch set is extending that to include keys on the new ".machine" keyring, by linking it to the secondary keyring.

Yes, it is an option, as long as it is documented correctly in the prepending kdoc the symbol name does not matter all that much.. /Jarkko

The series grew based on requests added in each round. How about I drop IMA support from the next round? This would eliminate nine patches from the series (5, 6, 7, 9-14), leaving six patches to introduce and enable the new machine keyring (3, 4, 8, 15-17). The first two patches could be taken today. The only reason the first two are included is to get this series through the kernel test robot. This would allow the machine keyring to be used for module signing. Afterwards I could introduce the CA restriction behind another Kconfig in a different series to add back IMA support. Let me know if this would be a better approach.

Once you allow ALL the MOK keys to be loaded onto the .machine keyring, limiting which keys should be loaded will change the existing expected behavior. So you indeed would need to define a new config option. Your patch set links the ".machine" keyring to the ".secondary_trusted_keys" kerying. Based on IMA_KEYRINGS_PERMIT_SIGNED_BY_BUILTIN_OR_SECONDARY config being enabled, determines whether IMA trusts the secondary keyring. From IMA_KEYRINGS_PERMIT_SIGNED_BY_BUILTIN_OR_SECONDARY: help Keys may be added to the IMA or IMA blacklist keyrings, if the key is validly signed by a CA cert in the system built-in or secondary trusted keyrings. Intermediate keys between those the kernel has compiled in and the IMA keys to be added may be added to the system secondary keyring, provided they are validly signed by a key already resident in the built-in or secondary trusted keyrings. A dependency to prevent enabling this configuration, if the ".machine" keyring is enabled, would need to be defined. thanks, Mimi
