aad5d334a6 Save ima-evm-utils sourceforge wiki
The sourceforge wiki info is dated and requires a major overhaul.  Some
of the information already exists in the linux kernel documentation.
For now, save it with the referenced html files.

c1635add22 Disable use of OpenSSL "engine" support
OpenSSL v3 "engine" support is deprecated and replaced with "providers".
Engine support will continue to work for a while, but results in
deprecated declaration and other messages.  One option is simply to hide
them ("-Wno-deprecated-declarations").  The other alternative is to
conditionally build ima-evm-utils without OpenSSL engine support and
without disabling deprecated declarations.

Based on "--disable-engine" or "--enable-engine=no" configuration
option, disable OpenSSL "engine" support.

As suggested by Vitaly,
- verify ENGINE_init symbol is defined in libcrypto
- disable engine support if either OPENSSL_NO_DYNAMIC_ENGINE or
OPENSSL_NO_ENGINE variables are defined

751a395772 Deprecate IMA signature version 1
The original IMA file signatures were based on a SHA1 hash.  Kernel
support for other hash algorithms was subsequently upstreamed.  Deprecate
"--rsa" support.

80bb310152 set default hash algorithm in configuration time
The default hash algorithm for evmctl is today hardcoded in the libimaevm.c
file. To facilitate package maintainers across different distributions to
set their own default hash algorithm, this patch adds the
--with-default-hash=<algo> option to the configuration script.

The chosen algorithm will then be checked by its available in the kernel,
otherwise IMA won't be able to verify files hashed by the user. For that,
the kernel header hash_info.h used as the source of supported hashes. In
case the hash_info.h header is not present, the configuration script warns
about it, but uses whatever the user specified in the option.

command line tools.

The algorithm_string_to_algid() function supports only the digest
algorithms in use.  The table has place holders for other algorithms
as they are needed and the C strings are defined.

The table can also be used for an algorithm ID to string function if
it's ever needed.

79ab82f55f Rename "Changelog" to "NEWS"
autoconfig requires the existence of a "NEWS" file.  "git log" is a better
changelog, and "ChangeLog" is really condensed and suitable to be NEWS.
After renaming ChangeLog to NEWS, autoconfig complains about the missing

Replacing the default automake GNU flavor with "foreign" removes the
requirement for defining the NEWS, COPYING, AUTHORS, ChangeLog, and

31ceff7eb6 ima-evm-utils: use tsspcrread to read the TPM 2.0 PCRs
The kernel does not expose the crypto agile TPM 2.0 PCR banks to
userspace like it exposes PCRs for TPM 1.2.  As a result, a userspace
application is required to read PCRs.

This patch adds tsspcrread support for reading the TPM 2.0 PCRs.
tsspcrread is one application included in the ibmtss package.

Sample error messages:
Failed to read PCRs: (tsspcrread failed: No such file or directory)
Failed to read PCRs: (TSS_Dev_Open: Error opening /dev/tpmrm0)

b628d8bfdb ima-evm-utils: Extract digest algorithms from hash_info.h
If configured with "--with-kernel-headers=PATH" try to extract hash
algorithms from "hash_info.h" from the kernel source tree or
kernel-headers package located in the specified path. (Otherwise, it
will be tried to get from the installed kernel.)

This also introduces two algorithm lists, one is built-in and another is
from the kernel source. (They should never contain conflicting algorithm
IDs by their append-only nature.) If the digest is not found in the
built-in list it will be searched in the list from kernel's
"hash_info.h".

This patch will allow evmctl to be just recompiled to work with digest
algorithms introduced in the newer kernels.

6aea54d2ad evmctl: use correct include for xattr.h
The xattr API/ABI is provided by both the c-library, as well as by the
libattr package. The c-library's header file is sys/xattr.h, whereas
libattr's header file can be found in attr/xattr.h.

Given none of the code here *links* against the libattr.so shared library, it
is wrong to *compile* against libattr's API (header file).

Doing so avoids confusion as to which xattr.h is used as the least problem,
and potential ABI differences as the worst problem due the mismatching header
file used.

So make sure we compile and link against the same thing, the c-library in
both cases.
