ima: load x509 certificate from the kernel
Define configuration option to load X509 certificate into the IMA trusted kernel keyring. It implements ima_load_x509() hook to load X509 certificate into the .ima trusted kernel keyring from the root filesystem. Changes in v3: * use ima_policy_flag in ima_get_action() ima_load_x509 temporarily clears ima_policy_flag to disable appraisal to load key. Use it to skip appraisal rules. * Key directory path changed to /etc/keys (Mimi) * Expand IMA_LOAD_X509 Kconfig help Changes in v2: * added '__init' * use ima_policy_flag to disable appraisal to load keys Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
