From fd5f4e9054acbf4f22fac81a358baf3c27aa42ac Mon Sep 17 00:00:00 2001 From: Dmitry Kasatkin Date: Wed, 5 Nov 2014 17:01:14 +0200 Subject: 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 Signed-off-by: Mimi Zohar --- security/integrity/integrity.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'security/integrity/integrity.h') diff --git a/security/integrity/integrity.h b/security/integrity/integrity.h index 1057abbd31cd..caa1f6ca72e9 100644 --- a/security/integrity/integrity.h +++ b/security/integrity/integrity.h @@ -162,6 +162,14 @@ static inline int asymmetric_verify(struct key *keyring, const char *sig, } #endif +#ifdef CONFIG_IMA_LOAD_X509 +void __init ima_load_x509(void); +#else +static inline void ima_load_x509(void) +{ +} +#endif + #ifdef CONFIG_INTEGRITY_AUDIT /* declarations */ void integrity_audit_msg(int audit_msgno, struct inode *inode, -- cgit v1.2.3
