patch 'crypto/qat: fix DOCSIS crash' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/22/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/5a12a4c1fa0e030e9c4197dc01751d82087a68af

Thanks.

Subject: [PATCH] crypto/qat: fix DOCSIS crash
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 03f0e3608d44d468b22ed17c30144d87edeb3ee9 ]

Currently if AES or DES algorithms fail for DOCSIS test suite,
a segmentation fault occurs when cryptodev_qat_autotest is ran.

This is due to a duplicate call of EVP_CIPHER_CTX_free for the
session context. Ctx is freed firstly in the bpi_cipher_ctx_init
function and then again at the end of qat_sym_session_configure_cipher
function.

This commit fixes this bug by removing the first instance
of EVP_CIPHER_CTX_free, leaving just the dedicated function in
the upper level to free the ctx.

Fixes: 98f060891615 ("crypto/qat: add symmetric session file")
