From: Akhil Goyal Date: Sun, 18 Oct 2020 09:40:41 +0000 (+0530) Subject: security: update session create API X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e30b2833c47c;p=dpdk.git security: update session create API The API ``rte_security_session_create`` takes only single mempool for session and session private data. So the application need to create mempool for twice the number of sessions needed and will also lead to wastage of memory as session private data need more memory compared to session. Hence the API is modified to take two mempool pointers - one for session and one for private data. This is very similar to crypto based session create APIs.

Also compile time flag ``RTE_ETHDEV_QUEUE_STAT_CNTRS`` will be removed. -* security: The API ``rte_security_session_create`` takes only single mempool - for session and session private data. So the application need to create - mempool for twice the number of sessions needed and will also lead to - wastage of memory as session private data need more memory compared to session. - Hence the API will be modified to take two mempool pointers - one for session - and one for private data. - * cryptodev: support for using IV with all sizes is added, J0 still can be used but only when IV length in following structs ``rte_crypto_auth_xform``, ``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal diff --git a/doc/guides/rel_notes/release_20_11.rst b/doc/guides/rel_notes/release_20_11.rst index 98043b7319..25ea3c20b4 100644 --- a/doc/guides/rel_notes/release_20_11.rst +++ b/doc/guides/rel_notes/release_20_11.rst @@ -473,6 +473,12 @@ API Changes ``uint32_t`` to ``uint8_t`` so that a new field ``sdap_enabled`` can be added to support SDAP. +* security: The API ``rte_security_session_create`` is updated to take two + mempool objects one for session and other for session private data. + So the application need to create two mempools and get the size of session + private data using API ``rte_security_session_get_size`` for private session + mempool. + * ipsec: ``RTE_SATP_LOG2_NUM`` has been dropped from ``enum`` and subsequently moved ``rte_ipsec`` lib from experimental to stable. diff --git a/examples/ipsec-secgw/ipsec-secgw.c b/examples/ipsec-secgw/ipsec-secgw.c index 58ecfd6f76..5ed4678d40 100644 --- a/examples/ipsec-secgw/ipsec-secgw.c +++ b/examples/ipsec-secgw/ipsec-secgw.c @@ -2348,12 +2348,8 @@ session_pool_init(struct socket_ctx *ctx, int32_t socket_id, size_t sess_sz) snprintf(mp_name, RTE_MEMPOOL_NAMESIZE, "sess_mp_%u", socket_id);
