> Commit 67ab783b5d70 ("crypto/openssl: use local copy for session
> contexts") introduced a fix for concurrency bugs which could occur when
> using one OpenSSL PMD session across multiple cores simultaneously. The
> solution was to clone the EVP contexts per-buffer to avoid them being
> used concurrently.
>
> However, part of commit 75adf1eae44f ("crypto/openssl: update HMAC
> routine with 3.0 EVP API") reverted this fix, only for combined ops
> (AES-GCM and AES-CCM).
>
> Fix the concurrency issue by cloning EVP contexts per-buffer. An extra
> workaround is required for OpenSSL versions which are >= 3.0.0, and
> <= 3.2.0. This is because, prior to OpenSSL 3.2.0, EVP_CIPHER_CTX_copy()
> is not implemented for AES-GCM or AES-CCM. When using these OpenSSL
> versions, create and initialise the context from scratch, per-buffer.
