-What: /sys/class/rfkill/rfkill[0-9]+/state
-Date: 09-Jul-2007
-KernelVersion v2.6.22
-Contact: linux-wireless@vger.kernel.org
-Description: Current state of the transmitter.
- This file is deprecated and scheduled to be removed in 2014,
- because its not possible to express the 'soft and hard block'
- state of the rfkill driver.
-Values: A numeric value.
- 0: RFKILL_STATE_SOFT_BLOCKED
- transmitter is turned off by software
- 1: RFKILL_STATE_UNBLOCKED
- transmitter is (potentially) active
- 2: RFKILL_STATE_HARD_BLOCKED
- transmitter is forced off by something outside of
- the driver's control.

+Checksum Offloads in the Linux Networking Stack
+
+
+Introduction
+============
+
+This document describes a set of techniques in the Linux networking stack
+ to take advantage of checksum offload capabilities of various NICs.
+
+The following technologies are described:
+ * TX Checksum Offload
+ * LCO: Local Checksum Offload
+ * RCO: Remote Checksum Offload
+
+Things that should be documented here but aren't yet:
+ * RX Checksum Offload
+ * CHECKSUM_UNNECESSARY conversion
+
+
+TX Checksum Offload
+===================
+
+The interface for offloading a transmit checksum to a device is explained
+ in detail in comments near the top of include/linux/skbuff.h.
+In brief, it allows to request the device fill in a single ones-complement
+ checksum defined by the sk_buff fields skb->csum_start and
+ skb->csum_offset. The device should compute the 16-bit ones-complement
+ checksum (i.e. the 'IP-style' checksum) from csum_start to the end of the
+ packet, and fill in the result at (csum_start + csum_offset).
+Because csum_offset cannot be negative, this ensures that the previous
+ value of the checksum field is included in the checksum computation, thus
+ it can be used to supply any needed corrections to the checksum (such as
+ the sum of the pseudo-header for UDP or TCP).
+This interface only allows a single checksum to be offloaded. Where
+ encapsulation is used, the packet may have multiple checksum fields in
+ different header layers, and the rest will have to be handled by another
+ mechanism such as LCO or RCO.
+No offloading of the IP header checksum is performed; it is always done in
+ software. This is OK because when we build the IP header, we obviously
+ have it in cache, so summing it isn't expensive. It's also rather short.
+The requirements for GSO are more complicated, because when segmenting an
+ encapsulated packet both the inner and outer checksums may need to be
+ edited or recomputed for each resulting segment. See the skbuff.h comment
+ (section 'E') for more details.
+
+A driver declares its offload capabilities in netdev->hw_features; see
+ Documentation/networking/netdev-features for more. Note that a device
+ which only advertises NETIF_F_IP[V6]_CSUM must still obey the csum_start
+ and csum_offset given in the SKB; if it tries to deduce these itself in
+ hardware (as some NICs do) the driver should check that the values in the
+ SKB match those which the hardware will deduce, and if not, fall back to
+ checksumming in software instead (with skb_checksum_help or one of the
+ skb_csum_off_chk* functions as mentioned in include/linux/skbuff.h). This
+ is a pain, but that's what you get when hardware tries to be clever.
+
+The stack should, for the most part, assume that checksum offload is
+ supported by the underlying device. The only place that should check is
+ validate_xmit_skb(), and the functions it calls directly or indirectly.
+ That function compares the offload features requested by the SKB (which
+ may include other offloads besides TX Checksum Offload) and, if they are
+ not supported or enabled on the device (determined by netdev->features),
+ performs the corresponding offload in software. In the case of TX
+ Checksum Offload, that means calling skb_checksum_help(skb).
+
+
+LCO: Local Checksum Offload
+===========================
+
+LCO is a technique for efficiently computing the outer checksum of an
+ encapsulated datagram when the inner checksum is due to be offloaded.
+The ones-complement sum of a correctly checksummed TCP or UDP packet is
+ equal to the sum of the pseudo header, because everything else gets
+ 'cancelled out' by the checksum field. This is because the sum was
+ complemented before being written to the checksum field.
+More generally, this holds in any case where the 'IP-style' ones complement
+ checksum is used, and thus any checksum that TX Checksum Offload supports.
+That is, if we have set up TX Checksum Offload with a start/offset pair, we
+ know that _after the device has filled in that checksum_, the ones
+ complement sum from csum_start to the end of the packet will be equal to
+ _whatever value we put in the checksum field beforehand_. This allows us
+ to compute the outer checksum without looking at the payload: we simply
+ stop summing when we get to csum_start, then add the 16-bit word at
+ (csum_start + csum_offset).
+Then, when the true inner checksum is filled in (either by hardware or by
+ skb_checksum_help()), the outer checksum will become correct by virtue of
+ the arithmetic.
+
+LCO is performed by the stack when constructing an outer UDP header for an
+ encapsulation such as VXLAN or GENEVE, in udp_set_csum(). Similarly for
+ the IPv6 equivalents, in udp6_set_csum().
+It is also performed when constructing an IPv4 GRE header, in
+ net/ipv4/ip_gre.c:build_header(). It is *not* currently performed when
+ constructing an IPv6 GRE header; the GRE checksum is computed over the
+ whole packet in net/ipv6/ip6_gre.c:ip6gre_xmit2(), but it should be
+ possible to use LCO here as IPv6 GRE still uses an IP-style checksum.
+All of the LCO implementations use a helper function lco_csum(), in
+ include/linux/skbuff.h.
+
+LCO can safely be used for nested encapsulations; in this case, the outer
+ encapsulation layer will sum over both its own header and the 'middle'
+ header. This does mean that the 'middle' header will get summed multiple
+ times, but there doesn't seem to be a way to avoid that without incurring
+ bigger costs (e.g. in SKB bloat).
+
+
+RCO: Remote Checksum Offload
+============================
+
+RCO is a technique for eliding the inner checksum of an encapsulated
+ datagram, allowing the outer checksum to be offloaded. It does, however,
+ involve a change to the encapsulation protocols, which the receiver must
+ also support. For this reason, it is disabled by default.
+RCO is detailed in the following Internet-Drafts:
+https://tools.ietf.org/html/draft-herbert-remotecsumoffload-00
+https://tools.ietf.org/html/draft-herbert-vxlan-rco-00
+In Linux, RCO is implemented individually in each encapsulation protocol,
+ and most tunnel types have flags controlling its use. For instance, VXLAN
+ has the flag VXLAN_F_REMCSUM_TX (per struct vxlan_rdst) to indicate that
+ RCO should be used when transmitting to a given remote destination.

+Kernel Connection Mulitplexor
+-----------------------------
+
+Kernel Connection Multiplexor (KCM) is a mechanism that provides a message based
+interface over TCP for generic application protocols. With KCM an application
+can efficiently send and receive application protocol messages over TCP using
+datagram sockets.
+
+KCM implements an NxM multiplexor in the kernel as diagrammed below:
+
++------------+ +------------+ +------------+ +------------+
+| KCM socket | | KCM socket | | KCM socket | | KCM socket |
++------------+ +------------+ +------------+ +------------+
+ | | | |

+ | | | | |

+ | | | | |
++----------+ +----------+ +----------+ +----------+ +----------+

++----------+ +----------+ +----------+ +----------+ +----------+
+ | | | | |
++----------+ +----------+ +----------+ +----------+ +----------+
+| TCP sock | | TCP sock | | TCP sock | | TCP sock | | TCP sock |
++----------+ +----------+ +----------+ +----------+ +----------+
+
+KCM sockets
+-----------
+
+The KCM sockets provide the user interface to the muliplexor. All the KCM sockets
+bound to a multiplexor are considered to have equivalent function, and I/O
+operations in different sockets may be done in parallel without the need for
+synchronization between threads in userspace.
+
+Multiplexor
+-----------
+
+The multiplexor provides the message steering. In the transmit path, messages
+written on a KCM socket are sent atomically on an appropriate TCP socket.
+Similarly, in the receive path, messages are constructed on each TCP socket
+(Psock) and complete messages are steered to a KCM socket.
+
+TCP sockets & Psocks
+--------------------
+
+TCP sockets may be bound to a KCM multiplexor. A Psock structure is allocated
+for each bound TCP socket, this structure holds the state for constructing
+messages on receive as well as other connection specific information for KCM.
+
+Connected mode semantics
+------------------------
+
+Each multiplexor assumes that all attached TCP connections are to the same
+destination and can use the different connections for load balancing when
+transmitting. The normal send and recv calls (include sendmmsg and recvmmsg)
+can be used to send and receive messages from the KCM socket.
+
+Socket types
+------------
+
+KCM supports SOCK_DGRAM and SOCK_SEQPACKET socket types.
+
+Message delineation
+-------------------
+
+Messages are sent over a TCP stream with some application protocol message
+format that typically includes a header which frames the messages. The length
+of a received message can be deduced from the application protocol header
+(often just a simple length field).
+
+A TCP stream must be parsed to determine message boundaries. Berkeley Packet
+Filter (BPF) is used for this. When attaching a TCP socket to a multiplexor a
+BPF program must be specified. The program is called at the start of receiving
+a new message and is given an skbuff that contains the bytes received so far.
+It parses the message header and returns the length of the message. Given this
+information, KCM will construct the message of the stated length and deliver it
+to a KCM socket.
+
+TCP socket management
+---------------------
+
+When a TCP socket is attached to a KCM multiplexor data ready (POLLIN) and
+write space available (POLLOUT) events are handled by the multiplexor. If there
+is a state change (disconnection) or other error on a TCP socket, an error is
+posted on the TCP socket so that a POLLERR event happens and KCM discontinues
+using the socket. When the application gets the error notification for a
+TCP socket, it should unattach the socket from KCM and then handle the error
+condition (the typical response is to close the socket and create a new
+connection if necessary).
+
+KCM limits the maximum receive message size to be the size of the receive
+socket buffer on the attached TCP socket (the socket buffer size can be set by
+SO_RCVBUF). If the length of a new message reported by the BPF program is
+greater than this limit a corresponding error (EMSGSIZE) is posted on the TCP
+socket. The BPF program may also enforce a maximum messages size and report an
+error when it is exceeded.
+
+A timeout may be set for assembling messages on a receive socket. The timeout
+value is taken from the receive timeout of the attached TCP socket (this is set
+by SO_RCVTIMEO). If the timer expires before assembly is complete an error
+(ETIMEDOUT) is posted on the socket.
+
+User interface
+==============
+
+Creating a multiplexor
+----------------------
+
+A new multiplexor and initial KCM socket is created by a socket call:
+
+ socket(AF_KCM, type, protocol)
+
+ - type is either SOCK_DGRAM or SOCK_SEQPACKET
+ - protocol is KCMPROTO_CONNECTED
+
+Cloning KCM sockets
+-------------------
+
+After the first KCM socket is created using the socket call as described
+above, additional sockets for the multiplexor can be created by cloning
+a KCM socket. This is accomplished by an ioctl on a KCM socket:
+
+ /* From linux/kcm.h */
+ struct kcm_clone {
+ int fd;
+ };
+
+ struct kcm_clone info;
+
+ memset(&info, 0, sizeof(info));
+
+ err = ioctl(kcmfd, SIOCKCMCLONE, &info);
+
+ if (!err)
+ newkcmfd = info.fd;
+
+Attach transport sockets
+------------------------
+
+Attaching of transport sockets to a multiplexor is performed by calling an
+ioctl on a KCM socket for the multiplexor. e.g.:
+
+ /* From linux/kcm.h */
+ struct kcm_attach {
+ int fd;
+ int bpf_fd;
+ };
+
+ struct kcm_attach info;
+
+ memset(&info, 0, sizeof(info));
+
+ info.fd = tcpfd;
+ info.bpf_fd = bpf_prog_fd;
+
+ ioctl(kcmfd, SIOCKCMATTACH, &info);
+
+The kcm_attach structure contains:
+ fd: file descriptor for TCP socket being attached
+ bpf_prog_fd: file descriptor for compiled BPF program downloaded
+
+Unattach transport sockets
+--------------------------
+
+Unattaching a transport socket from a multiplexor is straightforward. An
+"unattach" ioctl is done with the kcm_unattach structure as the argument:
+
+ /* From linux/kcm.h */
+ struct kcm_unattach {
+ int fd;
+ };
+
+ struct kcm_unattach info;
+
+ memset(&info, 0, sizeof(info));
+
+ info.fd = cfd;
+
+ ioctl(fd, SIOCKCMUNATTACH, &info);
+
+Disabling receive on KCM socket
+-------------------------------
+
+A setsockopt is used to disable or enable receiving on a KCM socket.
+When receive is disabled, any pending messages in the socket's
+receive buffer are moved to other sockets. This feature is useful
+if an application thread knows that it will be doing a lot of
+work on a request and won't be able to service new messages for a
+while. Example use:
+
+ int val = 1;
+
+ setsockopt(kcmfd, SOL_KCM, KCM_RECV_DISABLE, &val, sizeof(val))
+
+BFP programs for message delineation
+------------------------------------
+
+BPF programs can be compiled using the BPF LLVM backend. For exmple,
+the BPF program for parsing Thrift is:
+
+ #include "bpf.h" /* for __sk_buff */
+ #include "bpf_helpers.h" /* for load_word intrinsic */
+
+ SEC("socket_kcm")
+ int bpf_prog1(struct __sk_buff *skb)
+ {
+ return load_word(skb, 0) + 4;
+ }
+
+ char _license[] SEC("license") = "GPL";
+
+Use in applications
+===================
+
+KCM accelerates application layer protocols. Specifically, it allows
+applications to use a message based interface for sending and receiving
+messages. The kernel provides necessary assurances that messages are sent
+and received atomically. This relieves much of the burden applications have
+in mapping a message based protocol onto the TCP stream. KCM also make
+application layer messages a unit of work in the kernel for the purposes of
+steerng and scheduling, which in turn allows a simpler networking model in
+multithreaded applications.
+
+Configurations
+--------------
+
+In an Nx1 configuration, KCM logically provides multiple socket handles
+to the same TCP connection. This allows parallelism between in I/O
+operations on the TCP socket (for instance copyin and copyout of data is
+parallelized). In an application, a KCM socket can be opened for each
+processing thread and inserted into the epoll (similar to how SO_REUSEPORT
+is used to allow multiple listener sockets on the same port).
+
+In a MxN configuration, multiple connections are established to the
+same destination. These are used for simple load balancing.
+
+Message batching
+----------------
+
+The primary purpose of KCM is load balancing between KCM sockets and hence
+threads in a nominal use case. Perfect load balancing, that is steering
+each received message to a different KCM socket or steering each sent
+message to a different TCP socket, can negatively impact performance
+since this doesn't allow for affinities to be established. Balancing
+based on groups, or batches of messages, can be beneficial for performance.
+
+On transmit, there are three ways an application can batch (pipeline)
+messages on a KCM socket.
+ 1) Send multiple messages in a single sendmmsg.
+ 2) Send a group of messages each with a sendmsg call, where all messages
+ except the last have MSG_BATCH in the flags of sendmsg call.
+ 3) Create "super message" composed of multiple messages and send this
+ with a single sendmsg.
+
+On receive, the KCM module attempts to queue messages received on the
+same KCM socket during each TCP ready callback. The targeted KCM socket
+changes at each receive ready callback on the KCM socket. The application
+does not need to configure this.
+
+Error handling
+--------------
+
+An application should include a thread to monitor errors raised on
+the TCP connection. Normally, this will be done by placing each
+TCP socket attached to a KCM multiplexor in epoll set for POLLERR
+event. If an error occurs on an attached TCP socket, KCM sets an EPIPE
+on the socket thus waking up the application thread. When the application
+sees the error (which may just be a disconnect) it should unattach the
+socket from KCM and then close it. It is assumed that once an error is
+posted on the TCP socket the data stream is unrecoverable (i.e. an error
+may have occurred in in the middle of receiving a messssge).
+
+TCP connection monitoring
+-------------------------
+
+In KCM there is no means to correlate a message to the TCP socket that
+was used to send or receive the message (except in the case there is
+only one attached TCP socket). However, the application does retain
+an open file descriptor to the socket so it will be able to get statistics
+from the socket which can be used in detecting issues (such as high
+retransmissions on the socket).

-This file documents how to use memory mapped I/O with netlink.
-
-Author: Patrick McHardy <kaber@trash.net>
-
-Overview
---------
-
-Memory mapped netlink I/O can be used to increase throughput and decrease
-overhead of unicast receive and transmit operations. Some netlink subsystems
-require high throughput, these are mainly the netfilter subsystems
-nfnetlink_queue and nfnetlink_log, but it can also help speed up large
-dump operations of f.i. the routing database.
-
-Memory mapped netlink I/O used two circular ring buffers for RX and TX which
-are mapped into the processes address space.
-
-The RX ring is used by the kernel to directly construct netlink messages into
-user-space memory without copying them as done with regular socket I/O,
-additionally as long as the ring contains messages no recvmsg() or poll()
-syscalls have to be issued by user-space to get more message.
-
-The TX ring is used to process messages directly from user-space memory, the
-kernel processes all messages contained in the ring using a single sendmsg()
-call.
-
-Usage overview
---------------
-
-In order to use memory mapped netlink I/O, user-space needs three main changes:
-
-- ring setup
-- conversion of the RX path to get messages from the ring instead of recvmsg()
-- conversion of the TX path to construct messages into the ring
-
-Ring setup is done using setsockopt() to provide the ring parameters to the
-kernel, then a call to mmap() to map the ring into the processes address space:
-
-- setsockopt(fd, SOL_NETLINK, NETLINK_RX_RING, &params, sizeof(params));
-- setsockopt(fd, SOL_NETLINK, NETLINK_TX_RING, &params, sizeof(params));
-- ring = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0)
-
-Usage of either ring is optional, but even if only the RX ring is used the
-mapping still needs to be writable in order to update the frame status after
-processing.
-
-Conversion of the reception path involves calling poll() on the file
-descriptor, once the socket is readable the frames from the ring are
-processed in order until no more messages are available, as indicated by
-a status word in the frame header.
-
-On kernel side, in order to make use of memory mapped I/O on receive, the
-originating netlink subsystem needs to support memory mapped I/O, otherwise
-it will use an allocated socket buffer as usual and the contents will be
- copied to the ring on transmission, nullifying most of the performance gains.
-Dumps of kernel databases automatically support memory mapped I/O.
-
-Conversion of the transmit path involves changing message construction to
-use memory from the TX ring instead of (usually) a buffer declared on the
-stack and setting up the frame header appropriately. Optionally poll() can
-be used to wait for free frames in the TX ring.
-
-Structured and definitions for using memory mapped I/O are contained in
-<linux/netlink.h>.
-
-RX and TX rings
-----------------
-
-Each ring contains a number of continuous memory blocks, containing frames of
-fixed size dependent on the parameters used for ring setup.
-
-Ring: [ block 0 ]
- [ frame 0 ]
- [ frame 1 ]
- [ block 1 ]
- [ frame 2 ]
- [ frame 3 ]
- ...
- [ block n ]
- [ frame 2 * n ]
- [ frame 2 * n + 1 ]
-
-The blocks are only visible to the kernel, from the point of view of user-space
-the ring just contains the frames in a continuous memory zone.
-
-The ring parameters used for setting up the ring are defined as follows:
-
-struct nl_mmap_req {
- unsigned int nm_block_size;
- unsigned int nm_block_nr;
- unsigned int nm_frame_size;
- unsigned int nm_frame_nr;
-};
-
-Frames are grouped into blocks, where each block is a continuous region of memory
-and holds nm_block_size / nm_frame_size frames. The total number of frames in
-the ring is nm_frame_nr. The following invariants hold:
-
-- frames_per_block = nm_block_size / nm_frame_size
-
-- nm_frame_nr = frames_per_block * nm_block_nr
-
-Some parameters are constrained, specifically:
-
-- nm_block_size must be a multiple of the architectures memory page size.
- The getpagesize() function can be used to get the page size.
-
-- nm_frame_size must be equal or larger to NL_MMAP_HDRLEN, IOW a frame must be
- able to hold at least the frame header
-
-- nm_frame_size must be smaller or equal to nm_block_size
-
-- nm_frame_size must be a multiple of NL_MMAP_MSG_ALIGNMENT
-
-- nm_frame_nr must equal the actual number of frames as specified above.
-
-When the kernel can't allocate physically continuous memory for a ring block,
-it will fall back to use physically discontinuous memory. This might affect
-performance negatively, in order to avoid this the nm_frame_size parameter
-should be chosen to be as small as possible for the required frame size and
-the number of blocks should be increased instead.
-
-Ring frames
-------------
-
-Each frames contain a frame header, consisting of a synchronization word and some
-meta-data, and the message itself.
-
-Frame: [ header message ]
-
-The frame header is defined as follows:
-
-struct nl_mmap_hdr {
- unsigned int nm_status;
- unsigned int nm_len;
- __u32 nm_group;
- /* credentials */
- __u32 nm_pid;
- __u32 nm_uid;
- __u32 nm_gid;
-};
-
-- nm_status is used for synchronizing processing between the kernel and user-
- space and specifies ownership of the frame as well as the operation to perform
-
-- nm_len contains the length of the message contained in the data area
-
-- nm_group specified the destination multicast group of message
-
-- nm_pid, nm_uid and nm_gid contain the netlink pid, UID and GID of the sending
- process. These values correspond to the data available using SOCK_PASSCRED in
- the SCM_CREDENTIALS cmsg.
-
-The possible values in the status word are:
-
-- NL_MMAP_STATUS_UNUSED:
- RX ring: frame belongs to the kernel and contains no message
- for user-space. Approriate action is to invoke poll()
- to wait for new messages.
-
- TX ring: frame belongs to user-space and can be used for
- message construction.
-
-- NL_MMAP_STATUS_RESERVED:
- RX ring only: frame is currently used by the kernel for message
- construction and contains no valid message yet.
- Appropriate action is to invoke poll() to wait for
- new messages.
-
-- NL_MMAP_STATUS_VALID:
- RX ring: frame contains a valid message. Approriate action is
- to process the message and release the frame back to
- the kernel by setting the status to
- NL_MMAP_STATUS_UNUSED or queue the frame by setting the
- status to NL_MMAP_STATUS_SKIP.
-
- TX ring: the frame contains a valid message from user-space to
- be processed by the kernel. After completing processing
- the kernel will release the frame back to user-space by
- setting the status to NL_MMAP_STATUS_UNUSED.
-
-- NL_MMAP_STATUS_COPY:
- RX ring only: a message is ready to be processed but could not be
- stored in the ring, either because it exceeded the
- frame size or because the originating subsystem does
- not support memory mapped I/O. Appropriate action is
- to invoke recvmsg() to receive the message and release
- the frame back to the kernel by setting the status to
- NL_MMAP_STATUS_UNUSED.
-
-- NL_MMAP_STATUS_SKIP:
- RX ring only: user-space queued the message for later processing, but
- processed some messages following it in the ring. The
- kernel should skip this frame when looking for unused
- frames.
-
-The data area of a frame begins at a offset of NL_MMAP_HDRLEN relative to the
-frame header.
-
-TX limitations
---------------
-
-As of Jan 2015 the message is always copied from the ring frame to an
-allocated buffer due to unresolved security concerns.
-See commit 4682a0358639b29cf ("netlink: Always copy on mmap TX.").
