[RFC PATCH v8 06/17] uapi|audit: add ipe audit message definitions

Introduce new definitions to audit.h centered around trust decisions and policy loading and activation, as an extension of the mandatory access control fields. Signed-off-by: Deven Bowers <deven.desai(a)linux.microsoft.com&gt; --- v2: + Split evaluation loop, access control hooks, and evaluation loop from policy parser and userspace interface to pass mailing list character limit v3: + Move ipe_load_properties to patch 04. + Remove useless 0-initializations + Prefix extern variables with ipe_ + Remove kernel module parameters, as these are exposed through sysctls. + Add more prose to the IPE base config option help text. + Use GFP_KERNEL for audit_log_start. + Remove unnecessary caching system. + Remove comments from headers + Use rcu_access_pointer for rcu-pointer null check + Remove usage of reqprot; use prot only. + Move policy load and activation audit event to 03/12 v4: + Remove sysctls in favor of securityfs nodes + Re-add kernel module parameters, as these are now exposed through securityfs. + Refactor property audit loop to a separate function. v5: + fix minor grammatical errors + do not group rule by curly-brace in audit record, reconstruct the exact rule. v6: + No changes v7: + Further split audit system patch into two separate patches; one for include/uapi, and the usage of the new defines. + Change audit records to MAC region (14XX) from Integrity region (18XX), as IPE is an effectively a MAC system around authenticity versus an extension to the integrity subsystem. + Generalize the #defines to support the class of trust-based access-control LSMs. v8: + Change audit type: + AUDIT_TRUST_RESULT -> AUDIT_IPE_ACCESS + Remove audit types (replaced by existing types): + AUDIT_TRUST_POLICY_LOAD + AUDIT_TRUST_POLICY_ACTIVATE + AUDIT_TRUST_STATUS --- include/uapi/linux/audit.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/uapi/linux/audit.h b/include/uapi/linux/audit.h index 7c1dc818b1d5..78b9a04d5b41 100644 --- a/include/uapi/linux/audit.h +++ b/include/uapi/linux/audit.h @@ -143,6 +143,7 @@ #define AUDIT_MAC_UNLBL_STCDEL 1417 /* NetLabel: del a static label */ #define AUDIT_MAC_CALIPSO_ADD 1418 /* NetLabel: add CALIPSO DOI entry */ #define AUDIT_MAC_CALIPSO_DEL 1419 /* NetLabel: del CALIPSO DOI entry */ +#define AUDIT_IPE_ACCESS 1420 /* IPE Denial or Grant */ #define AUDIT_FIRST_KERN_ANOM_MSG 1700 #define AUDIT_LAST_KERN_ANOM_MSG 1799 -- 2.25.1
