One crypto hardware logical function (cpt-lf) per netdev is required for inline ipsec outbound functionality. Software prepare and submit crypto hardware (CPT) instruction for outbound inline ipsec crypto mode offload. The CPT instruction have details for encryption and authentication Crypto hardware encrypt, authenticate and provide the ESP packet to network hardware logic to transmit ipsec packet. First patch makes dma memory writable for in-place encryption, Second patch moves code to common file, Third patch disable backpressure on crypto (CPT) and network (NIX) hardware. Patch four onwards enables inline outbound ipsec. v4->v5: - Fixed un-initialized warning and pointer check (comment from Kalesh Anakkur Purayil) v3->v4: - Few error messages in datapath removed and some moved under netif_msg_tx_err(). - Added check for crypto offload (XFRM_DEV_OFFLOAD_CRYPTO) Thanks "Leon Romanovsky" for pointing out - Fixed codespell error as per comment from Simon Horman - Added some other cleanup comment from Kalesh Anakkur Purayil v2->v3: - Fix smatch and sparse erros (Comment from Simon Horman) - Fix build error with W=1 (Comment from Simon Horman) https://patchwork.kernel.org/project/netdevbpf/patch/20240513105446.297451-6-bbhushan2@marvell.com/ - Some other minor cleanup as per comment https://www.spinics.net/lists/netdev/msg997197.html v1->v2: - Fix compilation error to build driver a module - Use dma_wmb() instead of architecture specific barrier - Fix couple of other compilation warnings Bharat Bhushan (8): octeontx2-pf: map skb data as device writeable octeontx2-pf: Move skb fragment map/unmap to common code octeontx2-af: Disable backpressure between CPT and NIX cn10k-ipsec: Initialize crypto hardware for outb inline ipsec cn10k-ipsec: Add SA add/delete support for outb inline ipsec cn10k-ipsec: Process inline ipsec transmit offload cn10k-ipsec: Allow inline ipsec offload for skb with SA cn10k-ipsec: Enable outbound inline ipsec offload .../net/ethernet/marvell/octeontx2/af/mbox.h | 4 + .../ethernet/marvell/octeontx2/af/rvu_nix.c | 74 +- .../ethernet/marvell/octeontx2/nic/Makefile | 1 + .../marvell/octeontx2/nic/cn10k_ipsec.c | 1068 +++++++++++++++++ .../marvell/octeontx2/nic/cn10k_ipsec.h | 258 ++++ .../marvell/octeontx2/nic/otx2_common.c | 99 +- .../marvell/octeontx2/nic/otx2_common.h | 25 + .../marvell/octeontx2/nic/otx2_dcbnl.c | 3 + .../ethernet/marvell/octeontx2/nic/otx2_pf.c | 19 +- .../marvell/octeontx2/nic/otx2_txrx.c | 65 +- .../marvell/octeontx2/nic/otx2_txrx.h | 3 + .../ethernet/marvell/octeontx2/nic/otx2_vf.c | 10 +- 12 files changed, 1575 insertions(+), 54 deletions(-) create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/cn10k_ipsec.c create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/cn10k_ipsec.h
