bddf7343 - NIC KTLS for Chelsio T6 adapters.

Thu, 21 Nov 2019 19:30:31 +0000

NIC KTLS for Chelsio T6 adapters.This adds support for ifnet (NIC) KTLS using Chelsio T6 adapters.Unlike the TOE-based KTLS in r353328, NIC TLS works with non-TOEconnections.NIC KTLS on T6 is not able to use the normal TSO (LSO) path to segmentthe encrypted TLS frames output by the crypto engine. Instead, theTOE is placed into a special setup to permit "dummy" connections to beassociated with regular sockets using KTLS. This permits using theTOE to segment the encrypted TLS records. However, this approach doeshave 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 inon-card memory to handle retransmits, NIC KTLS must re-encrypt TLSrecords for retransmit requests as well as non-retransmit requeststhat do not include the start of a TLS record but do include thetrailer. The T6 NIC KTLS code tries to optimize some of the cases forrequests to transmit partial TLS records. In particular it attemptsto minimize sending "waste" bytes that have to be given as input tothe crypto engine but are not needed on the wire to satisfy mbufs sentfrom the TCP stack down to the driver.TCP packets for TLS requests are broken down into the followingclasses (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.To enable NIC KTLS with T6, set the following tunables prior toloading the cxgbe(4) driver:hw.cxgbe.config_file=kern_tlshw.cxgbe.kern_tls=1Reviewed by: npSponsored by: Chelsio CommunicationsDifferential Revision: https://reviews.freebsd.org/D21962 List of files: /freebsd-14.2/sys/modules/cxgbe/if_cxgbe/Makefile

Thu, 17 May 2018 01:42:18 +0000

cxgbe(4): Allocate offload Tx queues when a card has resourcesprovisioned for NIC_ETHOFLD and the kernel has option RATELIMIT.It is possible to use the chip's offload queues for normal NIC Tx andnot just TOE Tx. The difference is that these queues support out oforder processing of work requests and have a per-"flowid" mechanism fortracking credits between the driver and hardware. This allows Tx forany number of flows bound to different rate limits to be submitted to asingle Tx queue and the work requests for slow flows won't cause HOLblocking for the rest.Sponsored by: Chelsio Communications List of files: /freebsd-14.2/sys/modules/cxgbe/if_cxgbe/Makefile

f91fca5b - Add a driver to create VF devices on Chelsio T4/T5 NICs.

Fri, 22 Jul 2016 22:46:41 +0000

Add a driver to create VF devices on Chelsio T4/T5 NICs.Chelsio NICs are a bit unique compared to some other NICs in that theyexpose different functionality on different physical functions. Inparticular, PF4 is used to manage the NIC interfaces ('t4nex' and 't5nex').However, PF4 is not able to create VF devices. Instead, VFs are onlysupported by physical functions 0 through 3. This commit adds 't4iov'and 't5iov' drivers that attach to PF0-3.One extra wrinkle is that the iov devices cannot enable SR-IOV until thefirwmare has been initialized by the main PF4 driver. To handle thiscase, a new t4_if kobj interface has been added to permit cross-callsbetween the PF drivers. The PF4 driver notifies sibling drivers when itis fully attached. It also requests sibling drivers to detach before itdetaches. Sibling drivers query the PF4 driver during their attachroutine to see if it is attached. If not, the sibling drivers defertheir attach actions until the PF4 driver informs them it is attached.VF devices are associated with a single port on the NIC. VF devicescreated from PF0 are associated with the first port on the NIC, VFsfrom PF1 are associated with the second port, etc. VF devices canonly be created from a PF device that has an associated port. Thus,on a 2-port card, VFs are only supported on PF0 and PF1.Reviewed by: np (earlier versions)MFC after: 1 monthSponsored by: Chelsio Communications List of files: /freebsd-14.2/sys/modules/cxgbe/if_cxgbe/Makefile
