(Based on LTP "--verify" option.) - Ignore file measurement violations while verifying the IMA measurement list. (Based on LTP "--validate" option.) - Verify the file data signature included in the measurement list based on the file hash also included in the measurement list (--verify-sig) - Support original "ima" template (mixed templates not supported) * Support "sm3" crypto name Bug fixes and code cleanup: * Don't exit with -1 on failure, exit with 125 * On signature verification failure, include pathname. * Provide minimal hash_info.h file in case one doesn't exist, needed by the ima-evm-utils regression tests. * On systems with TPM 1.2, skip "boot_aggregate.test" using sample logs * Fix hash_algo type comparison mismatch * Simplify/clean up code * Address compiler complaints and failures * Fix memory allocations and leaks * Sanity check provided input files are regular files * Revert making "tsspcrread" a compile build time decision. * Limit additional messages based on log level (-v) 2019-07-30 Mimi Zohar <zohar@linux.ibm.com> version 1.2.1 Bug fixes: * When verifying multiple file signatures, return correct status * Don't automatically use keys from x509 certs if user supplied "--rsa" * Fix verifying DIGSIG_VERSION_1 signatures * autoconf, openssl fixes 2019-07-24 Mimi Zohar <zohar@linux.ibm.com> version 1.2 new features: * Generate EVM signatures based on the specified hash algorithm * include "security.apparmor" in EVM signature * Add support for writing & verifying "user.xxxx" xattrs for testing * Support Strebog/Gost hash functions * Add OpenSSL engine support * Use of EVP_PKEY OpenSSL API to generate/verify v2 signatures * Support verifying multiple signatures at once * Support new template "buf" field and warn about other unknown fields * Improve OpenSSL error reporting * Support reading TPM 2.0 PCRs using tsspcrread Bug fixes and code cleanup: * Update manpage stylesheet detection * Fix xattr.h include file * On error when reading TPM PCRs, don't log gargabe * Properly return keyid string to calc_keyid_v1/v2 callers, caused by limiting keyid output to verbose mode * Fix hash buffer overflow caused by EVM support for larger hashes, defined MAX_DIGEST_SIZE and MAX_SIGNATURE_SIZE, and added "asserts". * Linked with libcrypto instead of OpenSSL * Updated Autotools, replacing INCLUDES with AM_CPPFLAGS * Include new "hash-info.gen" in tar * Log the hash algorithm, not just the hash value * Fixed memory leaks in: EV_MD_CTX, init_public_keys * Fixed other warnings/bugs discovered by clang, coverity * Remove indirect calls in verify_hash() to improve code readability * Don't fallback to using sha1 * Namespace some too generic object names * Make functions/arrays static if possible 2018-01-28 Mimi Zohar <zohar@us.ibm.com> version 1.1 * Support the new openssl 1.1 api * Support for validating multiple pcrs * Verify the measurement list signature based on the list digest * Verify the "ima-sig" measurement list using multiple keys * Fixed parsing the measurement template data field length * Portable & immutable EVM signatures (new format) * Multiple fixes that have been lingering in the next branch.
