From 3be4beaf7c91ec9c6fefa5f11173af37113d10ae Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Tue, 20 Aug 2013 14:36:27 -0400 Subject: KEYS: verify a certificate is signed by a 'trusted' key Only public keys, with certificates signed by an existing 'trusted' key on the system trusted keyring, should be added to a trusted keyring. This patch adds support for verifying a certificate's signature. This is derived from David Howells pkcs7_request_asymmetric_key() patch. Changelog v6: - on error free key - Dmitry - validate trust only for not already trusted keys - Dmitry - formatting cleanup Changelog: - define get_system_trusted_keyring() to fix kbuild issues Signed-off-by: Mimi Zohar Signed-off-by: David Howells Acked-by: Dmitry Kasatkin --- include/keys/system_keyring.h | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/keys/system_keyring.h b/include/keys/system_keyring.h index 8dabc399bd1d..72665eb80692 100644 --- a/include/keys/system_keyring.h +++ b/include/keys/system_keyring.h @@ -17,7 +17,15 @@ #include extern struct key *system_trusted_keyring; - +static inline struct key *get_system_trusted_keyring(void) +{ + return system_trusted_keyring; +} +#else +static inline struct key *get_system_trusted_keyring(void) +{ + return NULL; +} #endif #endif /* _KEYS_SYSTEM_KEYRING_H */ -- cgit v1.2.3
