* [dpdk-dev] [PATCH] test: fix crypto_op length for sessionless case

Currently, private_data_offset for the sessionless is computed
wrongly which includes extra bytes added because of using
sizeof(struct rte_crypto_sym_xform) * 2) instead of
(sizeof(union rte_event_crypto_metadata)). Due to this buffer
overflow, the corruption was leading to test application
crash while freeing the ops mempool.

Fixes: 3c2c535ecfc0 ("test: add event crypto adapter auto-test")

Hi Aaron/dpdklab,

This patch's CI seems to have lot of false positive!
Ferruh triggered the re-test sometime back. Now, it is reporting less.
Could you please check from your end? Thanks!

Regards
Abhinandan

Only a malloc related unit test is still failing, which seems unrelated with the
patch. I am triggering it one more time, third time lucky.

Also after re-run, some tests passing now still shown as fail in the patchwork
checks table. Isn't re-run sending the patchwork test status again?

Hi all,

I have rerun the failing unit test. It also recreated the report, so
that category should be passing now.
Currently, I am looking more into the ABI test that is failing on
Arch, as well as the failures with DTS tests.
I will keep this thread updated.

Thanks,
Brandon

I do not understand the need for this patch.
Event metadata is copied after private data offset,
and this patch is changing the offset value.

You changed the value of len = iv_off + max_iv_len + metadata_size,
but metadata is copied after this 'len'. See this
rte_memcpy((uint8_t *)op + len, &m_data, sizeof(m_data));

I do not agree with this patch, am I missing something?

Op_mpool is created with element of priv_size = DEFAULT_NUM_XFORMS * sizeof(struct rte_crypto_sym_xform) + MAXIMUM_IV_LENGTH.
Whereas for the "sessionless" length is set to " uint32_t len = IV_OFFSET + MAXIMUM_IV_LENGTH + (sizeof(struct rte_crypto_sym_xform) * 2)"
Whereas, IV_OFFSET  = (sizeof(struct rte_crypto_op) + sizeof(struct rte_crypto_sym_op) + DEFAULT_NUM_XFORMS * sizeof(struct rte_crypto_sym_xform)).

So substituting IV_OFFSET, len = (sizeof(struct rte_crypto_op) + sizeof(struct rte_crypto_sym_op) + DEFAULT_NUM_XFORMS * sizeof(struct rte_crypto_sym_xform)) + MAXIMUM_IV_LENGTH + (sizeof(struct rte_crypto_sym_xform) * 2).
Which is a way ahead of the boundary which causes buffer overflow.

When memcpy is executed -> rte_memcpy((uint8_t *)op + len, &m_data, sizeof(m_data));
The m_data will overwrite the beyond the boundary. Hope this clarifies the need for fix.

You are setting len = sizeof(rte_crypto_op) + sizeof(rte_crypto_sym_op) + 2 *(sizeof(xform)) + IV_LEN + m_data_len
And then copying mdata at end of 'len', which is not correct. Here, len already include mdata and you are copying mdata after its designated space. Right? 
IMO, len should be set as IV_OFFSET+IV_LEN only.

Along with above changes, ops mempool has to be updated with sizeof(union rte_event_crypto_metadata) as below: 

	params.op_mpool = rte_crypto_op_pool_create(
			"EVENT_CRYPTO_SYM_OP_POOL",
			RTE_CRYPTO_OP_TYPE_SYMMETRIC,
			NUM_MBUFS, MBUF_CACHE_SIZE,
			DEFAULT_NUM_XFORMS *
			sizeof(struct rte_crypto_sym_xform) +
			MAXIMUM_IV_LENGTH +
+			sizeof(union rte_event_crypto_metadata),
			rte_socket_id());

Do you agree?
