[dpdk-dev] [dpdk-dev v1] test/cryptodev: fix incomplete data length

[dpdk-dev] [dpdk-dev v1] test/cryptodev: fix incomplete data length

[Kai Ji]

This patch fixes incorrect data lengths computation in cryptodev
unit test. Previously some data lengths were incorrectly set, which
was insensitive for crypto op unit tets but is critical for raw data
path API unit tests. The patch addressed the issue by setting the
correct data lengths for some tests.

Re: [dpdk-dev] [EXT] [dpdk-dev v1] test/cryptodev: fix incomplete data length

[Anoob Joseph]

Hi Kai,

Patch looks good. Wondering if we need same fix in functions such as " test_zuc_auth_cipher()".

We were also hitting this issue when we enabled few additional features in Marvell PMDs. Upon investigation, we realized that this issue would come up for certain packet size combinations if the padded lengths are not same. We observed the issue only with test_mixed_auth_cipher(), which is getting addressed with this patch. Just wondering if you have checked whether other places also would need a fix.

Thanks,
Anoob

[Anoob] Isn't ciphertext_pad_len guaranteed to be the larger one of the two? Do we need another variable and the RTE_MAX?

[Anoob] Now that more things are common across the branches, can we move out some bits outside the if condition? Like, the above line is definitely same and be kept outside condition. The append call prior to this can also be kept common if we can rename the local variable.

[Kai] Yes, this fix should apply to test_zuc_auth_cipher().  However,  I don't see any zuc test failed from my side as there  is no zuc test vector to cover the OOP partial digest case. I think I will add this fix into the zuc test anyway.

[Kai] the ciphertext_pad_len should be always bigger than plaintext_pad_len,  code changed in v2.

[dpdk-dev] [dpdk-dev v2] test/cryptodev: fix incomplete data length

[Kai Ji]

This patch fixes incorrect data lengths computation in cryptodev
unit test. Previously some data lengths were incorrectly set, which
was insensitive for crypto op unit tets but is critical for raw data
path API unit tests. The patch addressed the issue by setting the
correct data lengths for some tests.

[dpdk-dev] [dpdk-dev v3] test/cryptodev: fix incomplete data length

[Kai Ji]

This patch fixes incorrect data lengths computation in cryptodev
unit test. Previously some data lengths were incorrectly set, which
was insensitive for crypto op unit tets but is critical for raw data
path API unit tests. The patch addressed the issue by setting the
correct data lengths for some tests.

Fixes: 681f540da52b ("cryptodev: do not use AAD in wireless algorithms")
Cc: pablo.de.lara.guarch@intel.com

Fixes: e847fc512817 ("test/crypto: add encrypted digest case for AES-CTR-CMAC")
Cc: adamx.dybkowski@intel.com

Fixes: b1c1df46878d ("test/crypto: add ZUC test cases for auth-cipher")
Cc: damianx.nowak@intel.com

v2:
- review comments addressed

v3:
- remove unneeded debug code
