| 2009-02-13 | ima: fix build error | Randy Dunlap | |
| IMA_LSM_RULES requires AUDIT. This is automatic if SECURITY_SELINUX=y but not when SECURITY_SMACK=y (and SECURITY_SELINUX=n), so make the dependency explicit. This fixes the following build error: security/integrity/ima/ima_policy.c:111:error: implicit declaration of function 'security_audit_rule_match' security/integrity/ima/ima_policy.c:230:error: implicit declaration of function 'security_audit_rule_init' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org> | |||

| Support for a user loadable policy through securityfs with support for LSM specific policy data. - free invalid rule in ima_parse_add_rule() Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Acked-by: Serge Hallyn <serue@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org> | |||
| 2009-02-06 | integrity: IMA as an integrity service provider | Mimi Zohar | |
| IMA provides hardware (TPM) based measurement and attestation for file measurements. As the Trusted Computing (TPM) model requires, IMA measures all files before they are accessed in any way (on the integrity_bprm_check, integrity_path_check and integrity_file_mmap hooks), and commits the measurements to the TPM. Once added to the TPM, measurements can not be removed. In addition, IMA maintains a list of these file measurements, which can be used to validate the aggregate value stored in the TPM. The TPM can sign these measurements, and thus the system can prove, to itself and to a third party, the system's integrity in a way that cannot be circumvented by malicious or compromised software. - alloc ima_template_entry before calling ima_store_template() - log ima_add_boot_aggregate() failure - removed unused IMA_TEMPLATE_NAME_LEN - replaced hard coded string length with #define name Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org> | |||
