New functionality is being added to IMA to measure data provided by kernel components. With this feature, IMA policy can be set to enable measuring data provided by device-mapper targets. Currently one such device-mapper target - dm-crypt, is being updated to use this functionality. This new functionality needs test automation in LTP. Some of the existing functionality in ima_keys.sh can be reused for this, but it needs to be refactored into generic functions first. Add a testcase which verifies that the IMA subsystem correctly measures the data coming from a device-mapper target - dm-crypt. Refactor common functionality in ima_keys.sh for this, and move the generic functions to ima_setup.sh. This series needs a kernel built on the following repo/branch/patches: repo: https://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity.git branch: next-integrity commit aa662fc04f5b ("ima: Fix NULL pointer dereference in ima_file_hash") And the following patch series should be applied in the following order: 1. https://patchwork.kernel.org/patch/11795559/ 2. https://patchwork.kernel.org/patch/11801525/ 3. https://patchwork.kernel.org/patch/11743715/ Change Log v2: Incorporated feedback from Petr Vorel on v1. - Updated TST_NEEDS_CMDS to correctly reflects commands used in tests. - Removed unnecessary debugging info. - Refactored common functionality in ima_keys.sh, and moved the generic functions to ima_setup.sh. - Removed the use of eval, and replaced it with the recommended ROD() function. - All temporary files now get created under $TST_TMPDIR, instead of current directory. - Removed unnecessary TFAIL, to avoid double counting failures. - Updated log messages to be consistent. - Moved code to cleanup() to avoid code duplication.
