* [PATCH 1/5] crypto/openssl: fix GCM and CCM thread unsafe ctxs [not found] <20240603155555.1278010-1-jack.bond-preston@foss.arm.com> @ 2024-06-03 15:55 ` Jack Bond-Preston 0 siblings, 0 replies; 2+ messages in thread From: Jack Bond-Preston @ 2024-06-03 15:55 UTC (permalink / raw) To: jack.bond-preston; +Cc: stable, Wathsala Vithanage 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), with no explanation. This commit fixes the issue again, essentially reverting this part of the commit.
