From 2298d3964f1ce32d35bb7585e4fa224c5bf2c8d4 Mon Sep 17 00:00:00 2001
From: Ingo Franzki <ifranzki@linux.ibm.com>

Subject: [PATCH] provider: Default debug directory to /tmp but make it
configurable
The IBMCA provider debug logs were written to the /var/log/ibmca/ directory,
but this required that directory to be world-writable, because we don't know
under which user an application runs that uses the provider.
A world-writable directory under /var has security implications and should be
avoided.
Change the default log directory to /tmp which is world-writable anyway.
Additionally the log directory can now be configured via the 'debug-path'
option in the IBMCA provider section of the OpenSSL config file, or via
environment variable 'IBMCA_DEBUG_PATH'.
Closes: https://github.com/opencryptoki/openssl-ibmca/issues/107

Subject: [PATCH] provider: RSA: Fix get_params to retrieve max-size, bits, and
security-bits
The RSA key management's get_params() function should be able to return the
values for max-size, bits, and security-bits if at least the public key is
available.
The detection whether the key is 'empty', i.e. has neither the public nor the
private key components was wrong. This leads to the fact that those parameters
were not returned when only the public key was available.
