David Howells	99716b7cae	KEYS: Make the system trusted keyring depend on the asymmetric key type ... Make the system trusted keyring depend on the asymmetric key type as there's not a lot of point having it if you can't then load asymmetric keys onto it. This requires the ASYMMETRIC_KEY_TYPE to be made a bool, not a tristate, as the Kconfig language doesn't then correctly force ASYMMETRIC_KEY_TYPE to 'y' rather than 'm' if SYSTEM_TRUSTED_KEYRING is 'y'. Making SYSTEM_TRUSTED_KEYRING *select* ASYMMETRIC_KEY_TYPE instead doesn't work as the Kconfig interpreter then wrongly complains about dependency loops.

Mehmet Kayaalp	c4c3610595	KEYS: Reserve an extra certificate symbol for inserting without recompiling ... Place a system_extra_cert buffer of configurable size, right after the system_certificate_list, so that inserted keys can be readily processed by the existing mechanism. Added script takes a key file and a kernel image and inserts its contents to the reserved area. The system_certificate_list_size is also adjusted accordingly. Call the script as: scripts/insert-sys-cert -b <vmlinux> -c <certfile> If vmlinux has no symbol table, supply System.map file with -s flag. Subsequent runs replace the previously inserted key, instead of appending the new one.

David Howells	cfc411e7ff	Move certificate handling to its own directory ... Move certificate handling out of the kernel/ directory and into a certs/ directory to get all the weird stuff in one place and move the generated signing keys into this directory.
