* nvmf_che: NVMe-TCP offload support for Chelsio T7 adaptersJohn Baldwin2025-11-102-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides an alternative NVMe over TCP transport which uses PDU offload for TOE connections on a T7. Similar to iSCSI offload via cxgbei.ko, nvmf_che uses DDP when possible to enable the NIC to DMA received data directly into I/O data buffers (pages from a struct bio on the host side, pages from a CTL I/O requests on the controller side) to avoid copying data on the host CPU. nvmf_che is also able to receive a stream of C2H or H2C PDUs for a single data transfer when using DDP without processing the header of each PDU. Unlike cxgbei, nvmf_che aims to be mostly transparent to end users. Notably, neither nvmecontrol or ctld have to be explicitly asked to use an offload. Instead, TCP queue pairs are claimed by this driver whenever they are eligible (e.g., using TOE). The main restriction of nvmf_che compared to the software TCP transport is that Chelsio adapters have a restriction on the largest PDU that can be sent and received. When sending data, nvmf_che is able to split large C2H or H2C data requests across multiple PDUs without affecting nvmf(4) or nvmft(4). To avoid overly large PDUs when using nvmf(4), nvmf_che reports a data transfer limit that is honored by nvmf(4). This ensures that the remote controller's PDUs will never be too large (since the command transfer size is limited to one PDU) and also ensures that nvmf(4) will never to try to send a command PDU with ICD that is too large. For nvmft(4), overly large command PDUs due to ICD are avoided by clamping the size of the reported IOCCSZ in the controller data. However, to ensure that H2C PDUs are sufficiently small, nvmf_che will only claim queue pairs which advertised a suitable MAXH2CDATA parameter during queue negotiation. For ctld(8), this can be achieved by setting the MAXH2CDATA option in a transport-group, e.g. for T7: transport-group tg0 { discovery-auth-group no-authentication listen tcp 0.0.0.0 listen tcp [::] listen discovery-tcp 0.0.0.0 listen discovery-tcp [::] option MAXH2CDATA 32488 } Sponsored by: Chelsio Communications
* cxgbe: Support for NIC KTLS transmit on T7 adapters.John Baldwin2025-09-291-0/+1
| | | | | | | | | | | | | | | | | | | Unlike NIC KTLS support on T6, T7 is able to reuse the existing TSO functionality directly, including trimming the output of the crypto engine before it is passed on to TSO. This is much simpler and does not require the use of bypass pseudo-connections in the TOE engine. Among other things this permits arbitrary TCP options (including the full range of possible TCP timestamp values) while also avoiding various edge cases where parts of a requested TCP packet could not always be transmitted (e.g. partial trailers). This implementation also permits NIC KTLS to be used in parallel with TOE. This version does not yet support connections over a VF (specifically the ktls_tunnel_packet function needs to handle the VF work request), nor does it support VxLAN offload.

* cxgbe: Move the STAG and PBL memory pool arenas to the base driverJohn Baldwin2025-09-291-0/+1
| | | | | | | | | | | | | | Both RDMA (iw_cxgbe) and NVMe offloads use TPT table entries to map transaction tags in incoming PDUs to buffers in host memory permitting direct placement of received data into host memory buffers avoiding copies (iSCSI offload uses a different scheme for mapping tags to host memory). Move the vmem arenas for the supporting card memory regions from iw_cxgbe to the main driver so they can be shared with the NVMe offload driver. In addition, add some helper routines for constructing work requests to update TPT table entries. MFC after: 3 days Sponsored by: Chelsio Communications

* NIC KTLS for Chelsio T6 adapters.John Baldwin2019-11-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for ifnet (NIC) KTLS using Chelsio T6 adapters. Unlike the TOE-based KTLS in r353328, NIC TLS works with non-TOE connections. NIC KTLS on T6 is not able to use the normal TSO (LSO) path to segment the encrypted TLS frames output by the crypto engine. Instead, the TOE is placed into a special setup to permit "dummy" connections to be associated with regular sockets using KTLS. This permits using the TOE to segment the encrypted TLS records. However, this approach does have some limitations: 1) Regular TOE sockets cannot be used when the TOE is in this special mode. One can use either TOE and TOE-based KTLS or NIC KTLS, but not both at the same time. 2) In NIC KTLS mode, the TOE is only able to accept a per-connection timestamp offset that varies in the upper 4 bits. Put another way, only connections whose timestamp offset has the 28 lower bits cleared can use NIC KTLS and generate correct timestamps. The driver will refuse to enable NIC KTLS on connections with a timestamp offset with any of the lower 28 bits set. To use NIC KTLS, users can either disable TCP timestamps by setting the net.inet.tcp.rfc1323 sysctl to 0, or apply a local patch to the tcp_new_ts_offset() function to clear the lower 28 bits of the generated offset. 3) Because the TCP segmentation relies on fields mirrored in a TCB in the TOE, not all fields in a TCP packet can be sent in the TCP segments generated from a TLS record. Specifically, for packets containing TCP options other than timestamps, the driver will inject an "empty" TCP packet holding the requested options (e.g. a SACK scoreboard) along with the segments from the TLS record. These empty TCP packets are counted by the dev.cc.N.txq.M.kern_tls_options sysctls. Unlike TOE TLS which is able to buffer encrypted TLS records in on-card memory to handle retransmits, NIC KTLS must re-encrypt TLS records for retransmit requests as well as non-retransmit requests that do not include the start of a TLS record but do include the trailer. The T6 NIC KTLS code tries to optimize some of the cases for requests to transmit partial TLS records. In particular it attempts to minimize sending "waste" bytes that have to be given as input to the crypto engine but are not needed on the wire to satisfy mbufs sent from the TCP stack down to the driver. TCP packets for TLS requests are broken down into the following classes (with associated counters): - Mbufs that send an entire TLS record in full do not have any waste bytes (dev.cc.N.txq.M.kern_tls_full). - Mbufs that send a short TLS record that ends before the end of the trailer (dev.cc.N.txq.M.kern_tls_short). For sockets using AES-CBC, the encryption must always start at the beginning, so if the mbuf starts at an offset into the TLS record, the offset bytes will be "waste" bytes. For sockets using AES-GCM, the encryption can start at the 16 byte block before the starting offset capping the waste at 15 bytes. - Mbufs that send a partial TLS record that has a non-zero starting offset but ends at the end of the trailer (dev.cc.N.txq.M.kern_tls_partial). In order to compute the authentication hash stored in the trailer, the entire TLS record must be sent as input to the crypto engine, so the bytes before the offset are always "waste" bytes. In addition, other per-txq sysctls are provided: - dev.cc.N.txq.M.kern_tls_cbc: Count of sockets sent via this txq using AES-CBC. - dev.cc.N.txq.M.kern_tls_gcm: Count of sockets sent via this txq using AES-GCM. - dev.cc.N.txq.M.kern_tls_fin: Count of empty FIN-only packets sent to compensate for the TOE engine not being able to set FIN on the last segment of a TLS record if the TLS record mbuf had FIN set. - dev.cc.N.txq.M.kern_tls_records: Count of TLS records sent via this txq including full, short, and partial records. - dev.cc.N.txq.M.kern_tls_octets: Count of non-waste bytes (TLS header and payload) sent for TLS record requests. - dev.cc.N.txq.M.kern_tls_waste: Count of waste bytes sent for TLS record requests.

* Support for TLS offload of TOE connections on T6 adapters.John Baldwin2018-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TOE engine in Chelsio T6 adapters supports offloading of TLS encryption and TCP segmentation for offloaded connections. Sockets using TLS are required to use a set of custom socket options to upload RX and TX keys to the NIC and to enable RX processing. Currently these socket options are implemented as TCP options in the vendor specific range. A patched OpenSSL library will be made available in a port / package for use with the TLS TOE support. TOE sockets can either offload both transmit and reception of TLS records or just transmit. TLS offload (both RX and TX) is enabled by setting the dev.t6nex.<x>.tls sysctl to 1 and requires TOE to be enabled on the relevant interface. Transmit offload can be used on any "normal" or TLS TOE socket by using the custom socket option to program a transmit key. This permits most TOE sockets to transparently offload TLS when applications use a patched SSL library (e.g. using LD_LIBRARY_PATH to request use of a patched OpenSSL library). Receive offload can only be used with TOE sockets using the TLS mode. The dev.t6nex.0.toe.tls_rx_ports sysctl can be set to a list of TCP port numbers. Any connection with either a local or remote port number in that list will be created as a TLS socket rather than a plain TOE socket. Note that although this sysctl accepts an arbitrary list of port numbers, the sysctl(8) tool is only able to set sysctl nodes to a single value. A TLS socket will hang without receiving data if used by an application that is not using a patched SSL library. Thus, the tls_rx_ports node should be used with care. For a server mostly concerned with offloading TLS transmit, this node is not needed as plain TOE sockets will fall back to software crypto when using an unpatched SSL library. New per-interface statistics nodes are added giving counts of TLS packets and payload bytes (payload bytes do not include TLS headers or authentication tags/MACs) offloaded via the TOE engine, e.g.: dev.cc.0.stats.rx_tls_octets: 149 dev.cc.0.stats.rx_tls_records: 13 dev.cc.0.stats.tx_tls_octets: 26501823 dev.cc.0.stats.tx_tls_records: 1620 TLS transmit work requests are constructed by a new variant of t4_push_frames() called t4_push_tls_records() in tom/t4_tls.c. TLS transmit work requests require a buffer containing IVs. If the IVs are too large to fit into the work request, a separate buffer is allocated when constructing a work request. This buffer is associated with the transmit descriptor and freed when the descriptor is ACKed by the adapter. Received TLS frames use two new CPL messages. The first message is a CPL_TLS_DATA containing the decryped payload of a single TLS record. The handler places the mbuf containing the received payload on an mbufq in the TOE pcb. The second message is a CPL_RX_TLS_CMP message which includes a copy of the TLS header and indicates if there were any errors. The handler for this message places the TLS header into the socket buffer followed by the saved mbuf with the payload data. Both of these handlers are contained in tom/t4_tls.c. A few routines were exposed from t4_cpl_io.c for use by t4_tls.c including send_rx_credits(), a new send_rx_modulate(), and t4_close_conn(). TLS keys for both transmit and receive are stored in onboard memory in the NIC in the "TLS keys" memory region. In some cases a TLS socket can hang with pending data available in the NIC that is not delivered to the host. As a workaround, TLS sockets are more aggressive about sending CPL_RX_DATA_ACK messages anytime that any data is read from a TLS socket. In addition, a fallback timer will periodically send CPL_RX_DATA_ACK messages to the NIC for connections that are still in the handshake phase. Once the connection has finished the handshake and programmed RX keys via the socket option, the timer is stopped. A new function select_ulp_mode() is used to determine what sub-mode a given TOE socket should use (plain TOE, DDP, or TLS). The existing set_tcpddp_ulp_mode() function has been renamed to set_ulp_mode() and handles initialization of TLS-specific state when necessary in addition to DDP-specific state. Since TLS sockets do not receive individual TCP segments but always receive full TLS records, they can receive more data than is available in the current window (e.g. if a 16k TLS record is received but the socket buffer is itself 16k). To cope with this, just drop the window to 0 when this happens, but track the overage and "eat" the overage as it is read from the socket buffer not opening the window (or adding rx_credits) for the overage bytes.

* Add a driver for the Chelsio T6 crypto accelerator engine.John Baldwin2017-05-172-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ccr(4) driver supports use of the crypto accelerator engine on Chelsio T6 NICs in "lookaside" mode via the opencrypto framework. Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC, and SHA2-512-HMAC authentication algorithms. The driver also supports chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication algorithm for encrypt-then-authenticate operations. Note that this driver is still under active development and testing and may not yet be ready for production use. It does pass the tests in tests/sys/opencrypto with the exception that the AES-GCM implementation in the driver does not yet support requests with a zero byte payload. To use this driver currently, the "uwire" configuration must be used along with explicitly enabling support for lookaside crypto capabilities in the cxgbe(4) driver. These can be done by setting the following tunables before loading the cxgbe(4) driver: hw.cxgbe.config_file=uwire hw.cxgbe.cryptocaps_allowed=-1 MFC after: 1 month Relnotes: yes Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D10763 Notes: svn path=/head/; revision=318429

For now this capability is always enabled in kernels with options RATELIMIT. t4_tom will check if_capenable once the base driver gets code to support rate limiting for any socket (TOE or not). This was tested with iperf3 and netperf ToT as they already support SO_MAX_PACING_RATE sockopt. There is a bug in firmwares prior to 1.16.45.0 that affects the BSD driver only and results in rate-limiting at an incorrect rate. This will resolve by itself as soon as 1.16.45.0 or later firmware shows up in the driver. Relnotes: Yes Sponsored by: Chelsio Communications Notes: svn path=/head/; revision=317849
* cxgbe(4): Support routines for Tx traffic scheduling.Navdeep Parhar2017-05-021-0/+1
| | | | | | | | | | | | | | | | - Create a new file, t4_sched.c, and move all of the code related to traffic management from t4_main.c and t4_sge.c to this file. - Track both Channel Rate Limiter (ch_rl) and Class Rate Limiter (cl_rl) parameters in the PF driver. - Initialize all the cl_rl limiters with somewhat arbitrary default rates and provide routines to update them on the fly. - Provide routines to reserve and release traffic classes.
