commit 1e98001ff63cd7e75d95b4ea0d3d2a69965d8890
Author: Ingo Franzki <ifranzki@linux.ibm.com>
Date: Tue Feb 9 16:22:51 2021 +0100
SOFT: Fix problem with C_Get/SetOperationState and digest contexts
In commit 46829bf986d45262ad45c782c084a3f908f4acb8 the SOFT token was changed
to use OpenSSL's EVP interface for implementing SHA digest. With this change,
the OpenSSL digest context (EVP_MD_CTX) was saved in the DIGEST_CONTEXT's
context field. Since EVP_MD_CTX is opaque, its length is not known, so context_len
was set to 1.
This hinders C_Get/SetOperationState to correctly save and restore the digest
state, since the EVP_MD_CTX is not saved by C_GetOperationState, and
C_SetOperationState also can't restore the digest state, leaving a subsequent
C_DigestUpdate or C_DigestFinal with an invalid EVP_MD_CTX. This most likely
produces a segfault.
Fix this by saving the md_data from within the EVP_MD_CTX after each digest operation,
and restoring md_data on every operation with a fresh initialized EVP_MD_CTX.
