Re: [PATCH v6 04/25] X.509: Make certificate parser public

[sashiko-bot@kernel.org]

> From: Lukas Wunner <lukas@wunner.de>
> 
> The upcoming support for PCI device authentication with CMA-SPDM
> (PCIe r6.1 sec 6.31) requires validating the Subject Alternative Name
> in X.509 certificates.
> 
> High-level functions for X.509 parsing such as key_create_or_update()
> throw away the internal, low-level struct x509_certificate after
> extracting the struct public_key and public_key_signature from it.
> The Subject Alternative Name is thus inaccessible when using those
> functions.
> 
> Afford CMA-SPDM access to the Subject Alternative Name by making struct
> x509_certificate public, together with the functions for parsing an
> X.509 certificate into such a struct and freeing such a struct.
> 
> No functional change intended.
