    MODSIGN: Provide Kconfig options · ea0b6dcf
    David Howells 提交于
    Provide kernel configuration options for module signing.
    
    The following configuration options are added:
    
         CONFIG_MODULE_SIG_SHA1
         CONFIG_MODULE_SIG_SHA224
         CONFIG_MODULE_SIG_SHA256
         CONFIG_MODULE_SIG_SHA384
         CONFIG_MODULE_SIG_SHA512
    
    These select the cryptographic hash used to digest the data prior to signing.
    Additionally, the crypto module selected will be built into the kernel as it
    won't be possible to load it as a module without incurring a circular
    dependency when the kernel tries to check its signature.
