2012-02-28security: fix ima kconfig warningRandy Dunlap1-1/+1
Fix IMA kconfig warning on non-X86 architectures: warning: (IMA) selects TCG_TIS which has unmet direct dependencies (TCG_TPM && X86) Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Rajiv Andrade <srajiv@linux.vnet.ibm.com> Signed-off-by: James Morris <james.l.morris@oracle.com>

2011-07-18integrity: move ima inode integrity data managementMimi Zohar1-0/+1
Move the inode integrity data(iint) management up to the integrity directory in order to share the iint among the different integrity models. Changelog: - don't define MAX_DIGEST_SIZE - rename several globally visible 'ima_' prefixed functions, structs, locks, etc to 'integrity_' - replace '20' with SHA1_DIGEST_SIZE - reflect location change in appropriate Kconfig and Makefiles - remove unnecessary initialization of iint_initialized to 0 - rebased on current ima_iint.c - define integrity_iint_store/lock as static There should be no other functional changes.

2010-05-17ima: remove ACPI dependencyMimi Zohar1-3/+2
The ACPI dependency moved to the TPM, where it belongs. Although IMA per-se does not require access to the bios measurement log, verifying the IMA boot aggregate does, which requires ACPI. This patch prereq's 'TPM: ACPI/PNP dependency removal' http://lkml.org/lkml/2010/5/4/378.

2009-10-25LSM: imbed ima calls in the security hooksMimi Zohar1-0/+1
Based on discussions on LKML and LSM, where there are consecutive security_ and ima_ calls in the vfs layer, move the ima_ calls to the existing security_ hooks. Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
2009-02-13ima: fix build errorRandy Dunlap1-2/+2
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>

2009-02-06integrity: IMA as an integrity service providerMimi Zohar1-0/+49
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>
