The aim is to provide DPDK native high performance library for IPsec data-path processing. The library is supposed to utilize existing DPDK crypto-dev and security API to provide application with transparent IPsec processing API. The library is concentrated on data-path protocols processing (ESP and AH), IKE protocol(s) implementation is out of scope for that library. Current patch introduces SA-level API. SA (low) level API ================== API described below operates on SA level. It provides functionality that allows user for given SA to process inbound and outbound IPsec packets. To be more specific: - for inbound ESP/AH packets perform decryption, authentication, integrity checking, remove ESP/AH related headers - for outbound packets perform payload encryption, attach ICV, update/add IP headers, add ESP/AH headers/trailers, setup related mbuf felids (ol_flags, tx_offloads, etc.). - initialize/un-initialize given SA based on user provided parameters. The following functionality: - match inbound/outbound packets to particular SA - manage crypto/security devices - provide SAD/SPD related functionality - determine what crypto/security device has to be used for given packet(s) is out of scope for SA-level API. SA-level API is based on top of crypto-dev/security API and relies on them to perform actual cipher and integrity checking. To have an ability to easily map crypto/security sessions into related IPSec SA opaque userdata field was added into rte_cryptodev_sym_session and rte_security_session structures. That implies ABI change for both librte_crytpodev and librte_security. Due to the nature of crypto-dev API (enqueue/deque model) we use asynchronous API for IPsec packets destined to be processed by crypto-device. Expected API call sequence would be: /* enqueue for processing by crypto-device */ rte_ipsec_pkt_crypto_prepare(...); rte_cryptodev_enqueue_burst(...); /* dequeue from crypto-device and do final processing (if any) */ rte_cryptodev_dequeue_burst(...); rte_ipsec_pkt_crypto_group(...); /* optional */ rte_ipsec_pkt_process(...); Though for packets destined for inline processing no extra overhead is required and synchronous API call: rte_ipsec_pkt_process() is sufficient for that case. Current implementation supports all four currently defined rte_security types. Though to accommodate future custom implementations function pointers model is used for both for *crypto_prepare* and *process* impelementations.
