Add a new net_device_ops callback pointer, to address the first two of these. Separating them from .ndo_do_ioctl makes it easy to grep for drivers with a .ndo_siocdevprivate callback, and the unwieldy name hopefully makes it easier to spot in code review. By passing the ifreq structure and the ifr_data pointer separately, it is no longer necessary to overload these, and the driver can use either one for a given command.

Adjust the prototype to only pass the if_settings sub-structure in place of the ifreq, and remove the redundant 'cmd' argument in the process.

These behaviours have been chosen to map closely to the +existing sockets APIs. + +``bind()`` : set local socket address +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Sockets that receive incoming request packets will bind to a local address, +using the ``bind()`` syscall. + +.. code-block:: C + + struct sockaddr_mctp addr; + + addr.smctp_family = AF_MCTP; + addr.smctp_network = MCTP_NET_ANY; + addr.smctp_addr.s_addr = MCTP_ADDR_ANY; + addr.smctp_type = MCTP_TYPE_PLDM; + addr.smctp_tag = MCTP_TAG_OWNER; + + int rc = bind(sd, (struct sockaddr *)&addr, sizeof(addr)); + +This establishes the local address of the socket. Incoming MCTP messages that +match the network, address, and message type will be received by this socket. +The reference to 'incoming' is important here; a bound socket will only receive +messages with the TO bit set, to indicate an incoming request message, rather +than a response. + +The ``smctp_tag`` value will configure the tags accepted from the remote side of +this socket. Given the above, the only valid value is ``MCTP_TAG_OWNER``, which +will result in remotely "owned" tags being routed to this socket. Since +``MCTP_TAG_OWNER`` is set, the 3 least-significant bits of ``smctp_tag`` are not +used; callers must set them to zero. + +A ``smctp_network`` value of ``MCTP_NET_ANY`` will configure the socket to +receive incoming packets from any locally-connected network. A specific network +value will cause the socket to only receive incoming messages from that network. + +The ``smctp_addr`` field specifies a local address to bind to. A value of +``MCTP_ADDR_ANY`` configures the socket to receive messages addressed to any +local destination EID. + +The ``smctp_type`` field specifies which message types to receive. Only the +lower 7 bits of the type is matched on incoming messages (ie., the +most-significant IC bit is not part of the match). This results in the socket +receiving packets with and without a message integrity check footer. + +``sendto()``, ``sendmsg()``, ``send()`` : transmit an MCTP message +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +An MCTP message is transmitted using one of the ``sendto()``, ``sendmsg()`` or +``send()`` syscalls. Using ``sendto()`` as the primary example: + +.. code-block:: C + + struct sockaddr_mctp addr; + char buf[14]; + ssize_t len; + + /* set message destination */ + addr.smctp_family = AF_MCTP; + addr.smctp_network = 0; + addr.smctp_addr.s_addr = 8; + addr.smctp_tag = MCTP_TAG_OWNER; + addr.smctp_type = MCTP_TYPE_ECHO; + + /* arbitrary message to send, with message-type header */ + buf[0] = MCTP_TYPE_ECHO; + memcpy(buf + 1, "hello, world!", sizeof(buf) - 1); + + len = sendto(sd, buf, sizeof(buf), 0, + (struct sockaddr_mctp *)&addr, sizeof(addr)); + +The network and address fields of ``addr`` define the remote address to send to. +If ``smctp_tag`` has the ``MCTP_TAG_OWNER``, the kernel will ignore any bits set +in ``MCTP_TAG_VALUE``, and generate a tag value suitable for the destination +EID. If ``MCTP_TAG_OWNER`` is not set, the message will be sent with the tag +value as specified. If a tag value cannot be allocated, the system call will +report an errno of ``EAGAIN``. + +The application must provide the message type byte as the first byte of the +message buffer passed to ``sendto()``. If a message integrity check is to be +included in the transmitted message, it must also be provided in the message +buffer, and the most-significant bit of the message type byte must be 1. + +The ``sendmsg()`` system call allows a more compact argument interface, and the +message buffer to be specified as a scatter-gather list. At present no ancillary +message types (used for the ``msg_control`` data passed to ``sendmsg()``) are +defined. + +Transmitting a message on an unconnected socket with ``MCTP_TAG_OWNER`` +specified will cause an allocation of a tag, if no valid tag is already +allocated for that destination. The (destination-eid,tag) tuple acts as an +implicit local socket address, to allow the socket to receive responses to this +outgoing message. If any previous allocation has been performed (to for a +different remote EID), that allocation is lost. + +Sockets will only receive responses to requests they have sent (with TO=1) and +may only respond (with TO=0) to requests they have received. + +``recvfrom()``, ``recvmsg()``, ``recv()`` : receive an MCTP message +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +An MCTP message can be received by an application using one of the +``recvfrom()``, ``recvmsg()``, or ``recv()`` system calls.

If an +integrity check follows the message, it will be included in the received buffer. + +The ``recv()`` system call behaves in a similar way, but does not provide a +remote address to the application. Therefore, these are only useful if the +remote address is already known, or the message does not require a reply. + +Like the send calls, sockets will only receive responses to requests they have +sent (TO=1) and may only respond (TO=0) to requests they have received. diff --git a/MAINTAINERS b/MAINTAINERS index 4ca73465e690..73beb91891ee 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -11037,6 +11037,7 @@ M: Jeremy Kerr M: Matt Johnston L: netdev@vger.kernel.org S: Maintained +F: Documentation/networking/mctp.rst F: drivers/net/mctp/ F: include/net/mctp.h F: include/net/mctpdevice.h -- cgit v1.2.3 From d1626a1c273d0e66834006b10ebe12062dce2b6f Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Thu, 29 Jul 2021 20:19:01 +0300 Subject: docs: networking: dpaa2: document mirroring support on the switch Document the mirroring capabilities of the dpaa2-switch driver, any restrictions that are imposed and some example commands.

As the driver still feels like a Linux-2.2 era artifact today, it appears that the best way forward is to just delete it.

On active backup scenario, the MPTCP connection can do forward progress only due to MPTCP retransmissions - rtx can pick backup subflows. This patch introduces a new flag flow MPTCP subflows: if the underlying TCP connection made no progresses for long time, and there are other less problematic subflows available, the given subflow become stale. Stale subflows are not considered active: if all non backup subflows become stale, the MPTCP scheduler can pick backup subflows for plain transmissions. Stale subflows can return in active state, as soon as any reply from the peer is observed. Active backup scenarios can now leverage the available b/w with no restrinction.

No functional and performance changes are intended, but it makes it much easier to understand what's going on with how BPF programs are actually get executed. It's more obvious what types and callbacks are expected. Also extra () around input parameters can be dropped, as well as `__` variable prefixes intended to avoid naming collisions, which makes the code simpler to read and write. This refactoring also highlighted one extra issue. BPF_PROG_RUN is both a macro and an enum value (BPF_PROG_RUN == BPF_PROG_TEST_RUN). Turning BPF_PROG_RUN into a function causes naming conflict compilation error. So rename BPF_PROG_RUN into lower-case bpf_prog_run(), similar to bpf_prog_run_xdp(), bpf_prog_run_pin_on_cpu(), etc. All existing callers of BPF_PROG_RUN, the macro, are switched to bpf_prog_run() explicitly.

The intention for this file was to pull documentation from comments above API functions in libbpf. However, due to limitations of the kernel documentation system, this API documentation could not be versioned, which is counterintuative to how users expect to use it. There is also currently no doc comments, making this a blank page. Once the kernel comment documentation is actually contributed, it will still exist in the kernel repository, just in the code itself. A seperate site is being spun up to generate documentaiton from those comments in a way in which it can be versioned properly. This also reconfigures the bpf documentation index page to make it easier to sync to the previously mentioned documentaiton site.

In order to make it more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and 'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these parameters can be accessed by ethtool netlink coalesce uAPI. Also add an new structure kernel_ethtool_coalesce, then the new parameter can be added into this struct.
