+==========
+batman-adv
+==========
+
+Batman advanced is a new approach to wireless networking which does no longer
+operate on the IP basis. Unlike the batman daemon, which exchanges information
+using UDP packets and sets routing tables, batman-advanced operates on ISO/OSI
+Layer 2 only and uses and routes (or better: bridges) Ethernet Frames. It
+emulates a virtual network switch of all nodes participating. Therefore all
+nodes appear to be link local, thus all higher operating protocols won't be
+affected by any changes within the network. You can run almost any protocol
+above batman advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.
+
+Batman advanced was implemented as a Linux kernel driver to reduce the overhead
+to a minimum. It does not depend on any (other) network driver, and can be used
+on wifi as well as ethernet lan, vpn, etc ... (anything with ethernet-style
+layer 2).
+
+
+Configuration
+=============
+
+Load the batman-adv module into your kernel::
+
+  $ insmod batman-adv.ko
+
+The module is now waiting for activation. You must add some interfaces on which
+batman can operate. After loading the module batman advanced will scan your
+systems interfaces to search for compatible interfaces. Once found, it will
+create subfolders in the ``/sys`` directories of each supported interface,
+e.g.::
+
+  $ ls /sys/class/net/eth0/batman_adv/
+  elp_interval iface_status mesh_iface throughput_override
+
+If an interface does not have the ``batman_adv`` subfolder, it probably is not
+supported. Not supported interfaces are: loopback, non-ethernet and batman's
+own interfaces.
+
+Note: After the module was loaded it will continuously watch for new
+interfaces to verify the compatibility. There is no need to reload the module
+if you plug your USB wifi adapter into your machine after batman advanced was
+initially loaded.
+
+The batman-adv soft-interface can be created using the iproute2 tool ``ip``::
+
+  $ ip link add name bat0 type batadv
+
+To activate a given interface simply attach it to the ``bat0`` interface::
+
+  $ ip link set dev eth0 master bat0
+
+Repeat this step for all interfaces you wish to add. Now batman starts
+using/broadcasting on this/these interface(s).
+
+By reading the "iface_status" file you can check its status::
+
+  $ cat /sys/class/net/eth0/batman_adv/iface_status
+  active
+
+To deactivate an interface you have to detach it from the "bat0" interface::
+
+  $ ip link set dev eth0 nomaster
+
+
+All mesh wide settings can be found in batman's own interface folder::
+
+  $ ls /sys/class/net/bat0/mesh/
+  aggregated_ogms       fragmentation isolation_mark routing_algo
+  ap_isolation          gw_bandwidth  log_level      vlan0
+  bonding               gw_mode       multicast_mode
+  bridge_loop_avoidance gw_sel_class  network_coding
+  distributed_arp_table hop_penalty   orig_interval
+
+There is a special folder for debugging information::
+
+  $ ls /sys/kernel/debug/batman_adv/bat0/
+  bla_backbone_table log         neighbors         transtable_local
+  bla_claim_table    mcast_flags originators
+  dat_cache          nc          socket
+  gateways           nc_nodes    transtable_global
+
+Some of the files contain all sort of status information regarding the mesh
+network. For example, you can view the table of originators (mesh
+participants) with::
+
+  $ cat /sys/kernel/debug/batman_adv/bat0/originators
+
+Other files allow to change batman's behaviour to better fit your requirements.
+For instance, you can check the current originator interval (value in
+milliseconds which determines how often batman sends its broadcast packets)::
+
+  $ cat /sys/class/net/bat0/mesh/orig_interval
+  1000
+
+and also change its value::
+
+  $ echo 3000 > /sys/class/net/bat0/mesh/orig_interval
+
+In very mobile scenarios, you might want to adjust the originator interval to a
+lower value. This will make the mesh more responsive to topology changes, but
+will also increase the overhead.
+
+
+Usage
+=====
+
+To make use of your newly created mesh, batman advanced provides a new
+interface "bat0" which you should use from this point on. All interfaces added
+to batman advanced are not relevant any longer because batman handles them for
+you. Basically, one "hands over" the data by using the batman interface and
+batman will make sure it reaches its destination.
+
+The "bat0" interface can be used like any other regular interface. It needs an
+IP address which can be either statically configured or dynamically (by using
+DHCP or similar services)::
+
+  NodeA: ip link set up dev bat0
+  NodeA: ip addr add 192.168.0.1/24 dev bat0
+
+  NodeB: ip link set up dev bat0
+  NodeB: ip addr add 192.168.0.2/24 dev bat0
+  NodeB: ping 192.168.0.1
+
+Note: In order to avoid problems remove all IP addresses previously assigned to
+interfaces now used by batman advanced, e.g.::
+
+  $ ip addr flush dev eth0
+
+
+Logging/Debugging
+=================
+
+All error messages, warnings and information messages are sent to the kernel
+log. Depending on your operating system distribution this can be read in one of
+a number of ways. Try using the commands: ``dmesg``, ``logread``, or looking in
+the files ``/var/log/kern.log`` or ``/var/log/syslog``. All batman-adv messages
+are prefixed with "batman-adv:" So to see just these messages try::
+
+  $ dmesg | grep batman-adv
+
+When investigating problems with your mesh network, it is sometimes necessary to
+see more detail debug messages. This must be enabled when compiling the
+batman-adv module. When building batman-adv as part of kernel, use "make
+menuconfig" and enable the option ``B.A.T.M.A.N. debugging``
+(``CONFIG_BATMAN_ADV_DEBUG=y``).
+
+Those additional debug messages can be accessed using a special file in
+debugfs::
+
+  $ cat /sys/kernel/debug/batman_adv/bat0/log
+
+The additional debug output is by default disabled. It can be enabled during
+run time. Following log_levels are defined:
+
+.. flat-table::
+
+   * - 0
+     - All debug output disabled
+   * - 1
+     - Enable messages related to routing / flooding / broadcasting
+   * - 2
+     - Enable messages related to route added / changed / deleted
+   * - 4
+     - Enable messages related to translation table operations
+   * - 8
+     - Enable messages related to bridge loop avoidance
+   * - 16
+     - Enable messages related to DAT, ARP snooping and parsing
+   * - 32

-BATMAN-ADV
-----------
-
-Batman  advanced  is  a new approach to wireless networking which
-does no longer operate on the IP basis. Unlike the batman daemon,
-which  exchanges  information  using UDP packets and sets routing
-tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
-and  routes  (or  better: bridges) Ethernet Frames. It emulates a
-virtual network switch of all nodes participating.  Therefore all
-nodes  appear  to be link local, thus all higher operating proto-
-cols won't be affected by any changes within the network. You can
-run almost any protocol above batman advanced, prominent examples
-are: IPv4, IPv6, DHCP, IPX.
-
-Batman advanced was implemented as a Linux kernel driver  to  re-
-duce the overhead to a minimum. It does not depend on any (other)
-network driver, and can be used on wifi as well as ethernet  lan,
-vpn,  etc ... (anything with ethernet-style layer 2).
-
-
-CONFIGURATION
--------------
-
-Load the batman-adv module into your kernel:
-
-# insmod batman-adv.ko
-
-The  module  is now waiting for activation. You must add some in-
-terfaces on which batman can operate. After  loading  the  module
-batman  advanced  will scan your systems interfaces to search for
-compatible interfaces. Once found, it will create  subfolders  in
-the /sys directories of each supported interface, e.g.
-
-# ls /sys/class/net/eth0/batman_adv/
-# elp_interval  iface_status  mesh_iface  throughput_override
-
-If an interface does not have the "batman_adv" subfolder it prob-
-ably is not supported. Not supported  interfaces  are:  loopback,
-non-ethernet and batman's own interfaces.
-
-Note:  After the module was loaded it will continuously watch for
-new interfaces to verify the compatibility. There is no  need  to
-reload the module if you plug your USB wifi adapter into your ma-
-chine after batman advanced was initially loaded.
-
-The batman-adv soft-interface can be created using  the  iproute2
-tool "ip"
-
-# ip link add name bat0 type batadv
-
-To  activate a  given  interface  simply  attach it to the "bat0"
-interface
-
-# ip link set dev eth0 master bat0
-
-Repeat  this step for all interfaces you wish to add.  Now batman
-starts using/broadcasting on this/these interface(s).
-
-By reading the "iface_status" file you can check its status:
-
-# cat /sys/class/net/eth0/batman_adv/iface_status
-# active
-
-To  deactivate  an  interface  you  have   to  detach it from the
-"bat0" interface:
-
-# ip link set dev eth0 nomaster
-
-
-All  mesh  wide  settings  can be found in batman's own interface
-folder:
-
-# ls /sys/class/net/bat0/mesh/
-# aggregated_ogms        fragmentation  isolation_mark  routing_algo
-# ap_isolation           gw_bandwidth   log_level       vlan0
-# bonding                gw_mode        multicast_mode
-# bridge_loop_avoidance  gw_sel_class   network_coding
-# distributed_arp_table  hop_penalty    orig_interval
-
-There is a special folder for debugging information:
-
-# ls /sys/kernel/debug/batman_adv/bat0/
-# bla_backbone_table  log          neighbors          transtable_local
-# bla_claim_table     mcast_flags  originators
-# dat_cache           nc           socket
-# gateways            nc_nodes     transtable_global
-
-Some of the files contain all sort of status information  regard-
-ing  the  mesh  network.  For  example, you can view the table of
-originators (mesh participants) with:
-
-# cat /sys/kernel/debug/batman_adv/bat0/originators
-
-Other files allow to change batman's behaviour to better fit your
-requirements.  For instance, you can check the current originator
-interval (value in milliseconds which determines how often batman
-sends its broadcast packets):
-
-# cat /sys/class/net/bat0/mesh/orig_interval
-# 1000
-
-and also change its value:
-
-# echo 3000 > /sys/class/net/bat0/mesh/orig_interval
-
-In very mobile scenarios, you might want to adjust the originator
-interval to a lower value. This will make the mesh  more  respon-
-sive to topology changes, but will also increase the overhead.
-
-
-USAGE
------
-
-To  make use of your newly created mesh, batman advanced provides
-a new interface "bat0" which you should use from this  point  on.
-All  interfaces  added  to  batman  advanced are not relevant any
-longer because batman handles them for you. Basically, one "hands
-over" the data by using the batman interface and batman will make
-sure it reaches its destination.
-
-The "bat0" interface can be used like any  other  regular  inter-
-face.  It needs an IP address which can be either statically con-
-figured or dynamically (by using DHCP or similar services):
-
-# NodeA: ip link set up dev bat0
-# NodeA: ip addr add 192.168.0.1/24 dev bat0
-
-# NodeB: ip link set up dev bat0
-# NodeB: ip addr add 192.168.0.2/24 dev bat0
-# NodeB: ping 192.168.0.1
-
-Note:  In  order to avoid problems remove all IP addresses previ-
-ously assigned to interfaces now used by batman advanced, e.g.
-
-# ip addr flush dev eth0
-
-
-LOGGING/DEBUGGING
------------------
-
-All error messages, warnings and information messages are sent to
-the kernel log. Depending on your operating  system  distribution
-this  can  be read in one of a number of ways. Try using the com-
-mands: dmesg, logread, or looking in the files  /var/log/kern.log
-or  /var/log/syslog.  All  batman-adv  messages are prefixed with
-"batman-adv:" So to see just these messages try
-
-# dmesg | grep batman-adv
-
-When investigating problems with your mesh network  it  is  some-
-times  necessary  to see more detail debug messages. This must be
-enabled when compiling the batman-adv module. When building  bat-
-man-adv  as  part of kernel, use "make menuconfig" and enable the
-option "B.A.T.M.A.N. debugging".
-
-Those additional  debug messages can be accessed  using a special
-file in debugfs
-
-# cat /sys/kernel/debug/batman_adv/bat0/log
-
-The additional debug output is by default disabled. It can be en-
-abled  during run time. Following log_levels are defined:
-
-  0 - All  debug  output  disabled
-  1 - Enable messages related to routing / flooding / broadcasting
-  2 - Enable messages related to route added / changed / deleted
-  4 - Enable messages related to translation table operations
-  8 - Enable messages related to bridge loop avoidance
- 16 - Enable messages related to DAT, ARP snooping and parsing
- 32 - Enable messages related to network coding
- 64 - Enable messages related to multicast
-128 - Enable messages related to throughput meter
-255 - Enable all messages
-
-The debug output can be changed at runtime  using  the  file
-/sys/class/net/bat0/mesh/log_level. e.g.
-
-# echo 6 > /sys/class/net/bat0/mesh/log_level
-
-will enable debug messages for when routes change.
-
-Counters for different types of packets entering and leaving the
-batman-adv module are available through ethtool:
-
-# ethtool --statistics bat0

+DPAA IRQ Affinity and Receive Side Scaling
+==========================================
+
+Traffic coming on the DPAA Rx queues or on the DPAA Tx confirmation
+queues is seen by the CPU as ingress traffic on a certain portal.
+The DPAA QMan portal interrupts are affined each to a certain CPU.
+The same portal interrupt services all the QMan portal consumers.
+
+By default the DPAA Ethernet driver enables RSS, making use of the
+DPAA FMan Parser and Keygen blocks to distribute traffic on 128
+hardware frame queues using a hash on IP v4/v6 source and destination
+and L4 source and destination ports, in present in the received frame.
+When RSS is disabled, all traffic received by a certain interface is
+received on the default Rx frame queue. The default DPAA Rx frame
+queues are configured to put the received traffic into a pool channel
+that allows any available CPU portal to dequeue the ingress traffic.
+The default frame queues have the HOLDACTIVE option set, ensuring that
+traffic bursts from a certain queue are serviced by the same CPU.
+This ensures a very low rate of frame reordering. A drawback of this
+is that only one CPU at a time can service the traffic received by a
+certain interface when RSS is not enabled.
+
+To implement RSS, the DPAA Ethernet driver allocates an extra set of
+128 Rx frame queues that are configured to dedicated channels, in a
+round-robin manner. The mapping of the frame queues to CPUs is now
+hardcoded, there is no indirection table to move traffic for a certain
+FQ (hash result) to another CPU. The ingress traffic arriving on one
+of these frame queues will arrive at the same portal and will always
+be processed by the same CPU. This ensures intra-flow order preservation
+and workload distribution for multiple traffic flows.
+
+RSS can be turned off for a certain interface using ethtool, i.e.
+
+	# ethtool -N fm1-mac9 rx-flow-hash tcp4 ""
+
+To turn it back on, one needs to set rx-flow-hash for tcp4/6 or udp4/6:
+
+	# ethtool -N fm1-mac9 rx-flow-hash udp4 sfdn
+
+There is no independent control for individual protocols, any command
+run for one of tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 is
+going to control the rx-flow-hashing for all protocols on that interface.
+
+Besides using the FMan Keygen computed hash for spreading traffic on the
+128 Rx FQs, the DPAA Ethernet driver also sets the skb hash value when
+the NETIF_F_RXHASH feature is on (active by default). This can be turned
+on or off through ethtool, i.e.:
+
+	# ethtool -K fm1-mac9 rx-hashing off
+	# ethtool -k fm1-mac9 | grep hash
+	receive-hashing: off
+	# ethtool -K fm1-mac9 rx-hashing on
+	Actual changes:
+	receive-hashing: on
+	# ethtool -k fm1-mac9 | grep hash
+	receive-hashing: on
+
+Please note that Rx hashing depends upon the rx-flow-hashing being on
+for that interface - turning off rx-flow-hashing will also disable the
+rx-hashing (without ethtool reporting it as off as that depends on the
+NETIF_F_RXHASH feature flag).

+Register value tracking
+-----------------------
+In order to determine the safety of an eBPF program, the verifier must track
+the range of possible values in each register and also in each stack slot.
+This is done with 'struct bpf_reg_state', defined in include/linux/
+bpf_verifier.h, which unifies tracking of scalar and pointer values.  Each
+register state has a type, which is either NOT_INIT (the register has not been
+written to), SCALAR_VALUE (some value which is not usable as a pointer), or a
+pointer type.  The types of pointers describe their base, as follows:
+    PTR_TO_CTX          Pointer to bpf_context.
+    CONST_PTR_TO_MAP    Pointer to struct bpf_map.  "Const" because arithmetic
+                        on these pointers is forbidden.
+    PTR_TO_MAP_VALUE    Pointer to the value stored in a map element.
+    PTR_TO_MAP_VALUE_OR_NULL
+                        Either a pointer to a map value, or NULL; map accesses
+                        (see section 'eBPF maps', below) return this type,
+                        which becomes a PTR_TO_MAP_VALUE when checked != NULL.
+                        Arithmetic on these pointers is forbidden.
+    PTR_TO_STACK        Frame pointer.
+    PTR_TO_PACKET       skb->data.
+    PTR_TO_PACKET_END   skb->data + headlen; arithmetic forbidden.
+However, a pointer may be offset from this base (as a result of pointer
+arithmetic), and this is tracked in two parts: the 'fixed offset' and 'variable
+offset'.  The former is used when an exactly-known value (e.g. an immediate
+operand) is added to a pointer, while the latter is used for values which are
+not exactly known.  The variable offset is also used in SCALAR_VALUEs, to track
+the range of possible values in the register.
+The verifier's knowledge about the variable offset consists of:
+* minimum and maximum values as unsigned
+* minimum and maximum values as signed
+* knowledge of the values of individual bits, in the form of a 'tnum': a u64
+'mask' and a u64 'value'.  1s in the mask represent bits whose value is unknown;
+1s in the value represent bits known to be 1.  Bits known to be 0 have 0 in both
+mask and value; no bit should ever be 1 in both.  For example, if a byte is read
+into a register from memory, the register's top 56 bits are known zero, while
+the low 8 are unknown - which is represented as the tnum (0x0; 0xff).  If we
+then OR this with 0x40, we get (0x40; 0xcf), then if we add 1 we get (0x0;
+0x1ff), because of potential carries.
+Besides arithmetic, the register state can also be updated by conditional
+branches.  For instance, if a SCALAR_VALUE is compared > 8, in the 'true' branch
+it will have a umin_value (unsigned minimum value) of 9, whereas in the 'false'
+branch it will have a umax_value of 8.  A signed compare (with BPF_JSGT or
+BPF_JSGE) would instead update the signed minimum/maximum values.  Information
+from the signed and unsigned bounds can be combined; for instance if a value is
+first tested < 8 and then tested s> 4, the verifier will conclude that the value
+is also > 4 and s< 8, since the bounds prevent crossing the sign boundary.
+PTR_TO_PACKETs with a variable offset part have an 'id', which is common to all
+pointers sharing that same variable offset.  This is important for packet range
+checks: after adding some variable to a packet pointer, if you then copy it to
+another register and (say) add a constant 4, both registers will share the same
+'id' but one will have a fixed offset of +4.  Then if it is bounds-checked and
+found to be less than a PTR_TO_PACKET_END, the other register is now known to
+have a safe range of at least 4 bytes.  See 'Direct packet access', below, for
+more on PTR_TO_PACKET ranges.
+The 'id' field is also used on PTR_TO_MAP_VALUE_OR_NULL, common to all copies of
+the pointer returned from a map lookup.  This means that when one copy is
+checked and found to be non-NULL, all copies can become PTR_TO_MAP_VALUEs.
+As well as range-checking, the tracked information is also used for enforcing
+alignment of pointer accesses.  For instance, on most systems the packet pointer
+is 2 bytes after a 4-byte alignment.  If a program adds 14 bytes to that to jump
+over the Ethernet header, then reads IHL and addes (IHL * 4), the resulting
+pointer will have a variable offset known to be 4n+2 for some n, so adding the 2
+bytes (NET_IP_ALIGN) gives a 4-byte alignment and so word-sized accesses through
+that pointer are safe.

+R4=inv(id=0,umax_value=255,var_off=(0x0; 0xff)) which means that upper 56 bits
+of the register are guaranteed to be zero, and nothing is known about the lower
+8 bits. After insn 'r4 *= 14' the state becomes
+R4=inv(id=0,umax_value=3570,var_off=(0x0; 0xfffe)), since multiplying an 8-bit
+value by constant 14 will keep upper 52 bits as zero, also the least significant
+bit will be zero as 14 is even.  Similarly 'r2 >>= 48' will make
+R2=inv(id=0,umax_value=65535,var_off=(0x0; 0xffff)), since the shift is not sign
+extending.  This logic is implemented in adjust_reg_min_max_vals() function,
+which calls adjust_ptr_min_max_vals() for adding pointer to scalar (or vice
+versa) and adjust_scalar_min_max_vals() for operations on two scalars.

+MSG_ZEROCOPY
+============
+
+Intro
+=====
+
+The MSG_ZEROCOPY flag enables copy avoidance for socket send calls.
+The feature is currently implemented for TCP sockets.
+
+
+Opportunity and Caveats
+-----------------------
+
+Copying large buffers between user process and kernel can be
+expensive. Linux supports various interfaces that eschew copying,
+such as sendpage and splice. The MSG_ZEROCOPY flag extends the
+underlying copy avoidance mechanism to common socket send calls.
+
+Copy avoidance is not a free lunch. As implemented, with page pinning,
+it replaces per byte copy cost with page accounting and completion
+notification overhead. As a result, MSG_ZEROCOPY is generally only
+effective at writes over around 10 KB.
+
+Page pinning also changes system call semantics. It temporarily shares
+the buffer between process and network stack. Unlike with copying, the
+process cannot immediately overwrite the buffer after system call
+return without possibly modifying the data in flight. Kernel integrity
+is not affected, but a buggy program can possibly corrupt its own data
+stream.
+
+The kernel returns a notification when it is safe to modify data.
+Converting an existing application to MSG_ZEROCOPY is not always as
+trivial as just passing the flag, then.
+

+
+
+Interface
+=========
+
+Passing the MSG_ZEROCOPY flag is the most obvious step to enable copy
+avoidance, but not the only one.
+
+Socket Setup
+------------
+
+The kernel is permissive when applications pass undefined flags to the
+send system call. By default it simply ignores these. To avoid enabling
+copy avoidance mode for legacy processes that accidentally already pass
+this flag, a process must first signal intent by setting a socket option:
+
+::
+
+	if (setsockopt(fd, SOL_SOCKET, SO_ZEROCOPY, &one, sizeof(one)))
+		error(1, errno, "setsockopt zerocopy");
+
+
+Transmission
+------------
+
+The change to send (or sendto, sendmsg, sendmmsg) itself is trivial.
+Pass the new flag.
+
+::
+
+	ret = send(fd, buf, sizeof(buf), MSG_ZEROCOPY);
+
+A zerocopy failure will return -1 with errno ENOBUFS. This happens if
+the socket option was not set, the socket exceeds its optmem limit or
+the user exceeds its ulimit on locked pages.
+
+
+Mixing copy avoidance and copying
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Many workloads have a mixture of large and small buffers. Because copy
+avoidance is more expensive than copying for small packets, the
+feature is implemented as a flag. It is safe to mix calls with the flag
+with those without.
+
+
+Notifications
+-------------
+
+The kernel has to notify the process when it is safe to reuse a
+previously passed buffer. It queues completion notifications on the
+socket error queue, akin to the transmit timestamping interface.
+
+The notification itself is a simple scalar value. Each socket
+maintains an internal unsigned 32-bit counter. Each send call with
+MSG_ZEROCOPY that successfully sends data increments the counter. The
+counter is not incremented on failure or if called with length zero.
+The counter counts system call invocations, not bytes. It wraps after
+UINT_MAX calls.
+
+
+Notification Reception
+~~~~~~~~~~~~~~~~~~~~~~
+
+The below snippet demonstrates the API. In the simplest case, each
+send syscall is followed by a poll and recvmsg on the error queue.
+
+Reading from the error queue is always a non-blocking operation. The
+poll call is there to block until an error is outstanding. It will set
+POLLERR in its output flags. That flag does not have to be set in the
+events field. Errors are signaled unconditionally.
+
+::
+
+	pfd.fd = fd;
+	pfd.events = 0;
+	if (poll(&pfd, 1, -1) != 1 || pfd.revents & POLLERR == 0)
+		error(1, errno, "poll");
+
+	ret = recvmsg(fd, &msg, MSG_ERRQUEUE);
+	if (ret == -1)
+		error(1, errno, "recvmsg");
+
+	read_notification(msg);
+
+The example is for demonstration purpose only. In practice, it is more
+efficient to not wait for notifications, but read without blocking
+every couple of send calls.
+
+Notifications can be processed out of order with other operations on
+the socket. A socket that has an error queued would normally block
+other operations until the error is read. Zerocopy notifications have
+a zero error code, however, to not block send and recv calls.
+
+
+Notification Batching
+~~~~~~~~~~~~~~~~~~~~~
+
+Multiple outstanding packets can be read at once using the recvmmsg
+call. This is often not needed. In each message the kernel returns not
+a single value, but a range. It coalesces consecutive notifications
+while one is outstanding for reception on the error queue.
+
+When a new notification is about to be queued, it checks whether the
+new value extends the range of the notification at the tail of the
+queue. If so, it drops the new notification packet and instead increases
+the range upper value of the outstanding notification.
+
+For protocols that acknowledge data in-order, like TCP, each
+notification can be squashed into the previous one, so that no more
+than one notification is outstanding at any one point.
+
+Ordered delivery is the common case, but not guaranteed. Notifications
+may arrive out of order on retransmission and socket teardown.
+
+
+Notification Parsing
+~~~~~~~~~~~~~~~~~~~~
+
+The below snippet demonstrates how to parse the control message: the
+read_notification() call in the previous snippet. A notification
+is encoded in the standard error format, sock_extended_err.
+
+The level and type fields in the control data are protocol family
+specific, IP_RECVERR or IPV6_RECVERR.
+
+Error origin is the new type SO_EE_ORIGIN_ZEROCOPY. ee_errno is zero,
+as explained before, to avoid blocking read and write system calls on
+the socket.
+
+The 32-bit notification range is encoded as [ee_info, ee_data]. This
+range is inclusive. Other fields in the struct must be treated as
+undefined, bar for ee_code, as discussed below.
+
+::
+
+	struct sock_extended_err *serr;
+	struct cmsghdr *cm;
+
+	cm = CMSG_FIRSTHDR(msg);
+	if (cm->cmsg_level != SOL_IP &&
+	    cm->cmsg_type != IP_RECVERR)
+		error(1, 0, "cmsg");
+
+	serr = (void *) CMSG_DATA(cm);
+	if (serr->ee_errno != 0 ||
+	    serr->ee_origin != SO_EE_ORIGIN_ZEROCOPY)
+		error(1, 0, "serr");
+
+	printf("completed: %u..%u\n", serr->ee_info, serr->ee_data);
+
+
+Deferred copies
+~~~~~~~~~~~~~~~
+
+Passing flag MSG_ZEROCOPY is a hint to the kernel to apply copy
+avoidance, and a contract that the kernel will queue a completion
+notification. It is not a guarantee that the copy is elided.
+
+Copy avoidance is not always feasible. Devices that do not support
+scatter-gather I/O cannot send packets made up of kernel generated
+protocol headers plus zerocopy user data. A packet may need to be
+converted to a private copy of data deep in the stack, say to compute
+a checksum.
+
+In all these cases, the kernel returns a completion notification when
+it releases its hold on the shared pages. That notification may arrive
+before the (copied) data is fully transmitted. A zerocopy completion
+notification is not a transmit completion notification, therefore.
+
+Deferred copies can be more expensive than a copy immediately in the
+system call, if the data is no longer warm in the cache. The process
+also incurs notification processing cost for no benefit. For this
+reason, the kernel signals if data was completed with a copy, by
+setting flag SO_EE_CODE_ZEROCOPY_COPIED in field ee_code on return.
+A process may use this signal to stop passing flag MSG_ZEROCOPY on
+subsequent requests on the same socket.
+
+
+Implementation
+==============
+
+Loopback
+--------
+
+Data sent to local sockets can be queued indefinitely if the receive
+process does not read its socket. Unbound notification latency is not
+acceptable. For this reason all packets generated with MSG_ZEROCOPY
+that are looped to a local socket will incur a deferred copy. This
+includes looping onto packet sockets (e.g., tcpdump) and tun devices.
+
+
+Testing
+=======
+
+More realistic example code can be found in the kernel source under
+tools/testing/selftests/net/msg_zerocopy.c.
+
+Be cognizant of the loopback constraint. The test can be run between
+a pair of hosts. But if run between a local pair of processes, for
+instance when run with msg_zerocopy.sh between a veth pair across
+namespaces, the test will not show any improvement. For testing, the
+loopback restriction can be temporarily relaxed by making
+skb_orphan_frags_rx identical to skb_orphan_frags.

+Hyper-V network driver
+======================
+
+Compatibility
+=============
+
+This driver is compatible with Windows Server 2012 R2, 2016 and
+Windows 10.
+
+Features
+========
+
+  Checksum offload
+  ----------------
+  The netvsc driver supports checksum offload as long as the
+  Hyper-V host version does. Windows Server 2016 and Azure
+  support checksum offload for TCP and UDP for both IPv4 and
+  IPv6. Windows Server 2012 only supports checksum offload for TCP.
+
+  Receive Side Scaling
+  --------------------
+  Hyper-V supports receive side scaling. For TCP, packets are
+  distributed among available queues based on IP address and port
+  number.
+
+  For UDP, we can switch UDP hash level between L3 and L4 by ethtool
+  command. UDP over IPv4 and v6 can be set differently. The default
+  hash level is L4. We currently only allow switching TX hash level
+  from within the guests.
+
+  On Azure, fragmented UDP packets have high loss rate with L4
+  hashing. Using L3 hashing is recommended in this case.
+
+  For example, for UDP over IPv4 on eth0:
+  To include UDP port numbers in hashing:
+        ethtool -N eth0 rx-flow-hash udp4 sdfn
+  To exclude UDP port numbers in hashing:
+        ethtool -N eth0 rx-flow-hash udp4 sd
+  To show UDP hash level:
+        ethtool -n eth0 rx-flow-hash udp4
+
+  Generic Receive Offload, aka GRO
+  --------------------------------
+  The driver supports GRO and it is enabled by default. GRO coalesces
+  like packets and significantly reduces CPU usage under heavy Rx
+  load.
+
+  SR-IOV support
+  --------------
+  Hyper-V supports SR-IOV as a hardware acceleration option. If SR-IOV
+  is enabled in both the vSwitch and the guest configuration, then the
+  Virtual Function (VF) device is passed to the guest as a PCI
+  device. In this case, both a synthetic (netvsc) and VF device are
+  visible in the guest OS and both NIC's have the same MAC address.
+
+  The VF is enslaved by netvsc device.  The netvsc driver will transparently
+  switch the data path to the VF when it is available and up.
+  Network state (addresses, firewall, etc) should be applied only to the
+  netvsc device; the slave device should not be accessed directly in
+  most cases.  The exceptions are if some special queue discipline or
+  flow direction is desired, these should be applied directly to the
+  VF slave device.
+
+  Receive Buffer
+  --------------
+  Packets are received into a receive area which is created when device
+  is probed. The receive area is broken into MTU sized chunks and each may
+  contain one or more packets. The number of receive sections may be changed
+  via ethtool Rx ring parameters.
+
+  There is a similar send buffer which is used to aggregate packets for sending.
+  The send area is broken into chunks of 6144 bytes, each of section may
+  contain one or more packets. The send buffer is an optimization, the driver
+  will use slower method to handle very large packets or if the send buffer
+  area is exhausted.

+1. Introduction
+
+rmnet driver is used for supporting the Multiplexing and aggregation
+Protocol (MAP). This protocol is used by all recent chipsets using Qualcomm
+Technologies, Inc. modems.
+
+This driver can be used to register onto any physical network device in
+IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
+
+Multiplexing allows for creation of logical netdevices (rmnet devices) to
+handle multiple private data networks (PDN) like a default internet, tethering,
+multimedia messaging service (MMS) or IP media subsystem (IMS). Hardware sends
+packets with MAP headers to rmnet. Based on the multiplexer id, rmnet
+routes to the appropriate PDN after removing the MAP header.
+
+Aggregation is required to achieve high data rates. This involves hardware
+sending aggregated bunch of MAP frames. rmnet driver will de-aggregate
+these MAP frames and send them to appropriate PDN's.
+
+2. Packet format
+
+a. MAP packet (data / control)
+
+MAP header has the same endianness of the IP packet.
+
+Packet format -
+
+Bit             0             1           2-7      8 - 15           16 - 31
+Function   Command / Data   Reserved     Pad   Multiplexer ID    Payload length
+Bit            32 - x
+Function     Raw  Bytes
+
+Command (1)/ Data (0) bit value is to indicate if the packet is a MAP command
+or data packet. Control packet is used for transport level flow control. Data
+packets are standard IP packets.
+
+Reserved bits are usually zeroed out and to be ignored by receiver.
+
+Padding is number of bytes to be added for 4 byte alignment if required by
+hardware.
+
+Multiplexer ID is to indicate the PDN on which data has to be sent.
+
+Payload length includes the padding length but does not include MAP header
+length.
+
+b. MAP packet (command specific)
+
+Bit             0             1           2-7      8 - 15           16 - 31
+Function   Command         Reserved     Pad   Multiplexer ID    Payload length
+Bit          32 - 39        40 - 45    46 - 47       48 - 63
+Function   Command name    Reserved   Command Type   Reserved
+Bit          64 - 95
+Function   Transaction ID
+Bit          96 - 127
+Function   Command data
+
+Command 1 indicates disabling flow while 2 is enabling flow
+
+Command types -
+0 for MAP command request
+1 is to acknowledge the receipt of a command
+2 is for unsupported commands
+3 is for error during processing of commands
+
+c. Aggregation
+
+Aggregation is multiple MAP packets (can be data or command) delivered to
+rmnet in a single linear skb. rmnet will process the individual
+packets and either ACK the MAP command or deliver the IP packet to the
+network stack as needed
+
+MAP header|IP Packet|Optional padding|MAP header|IP Packet|Optional padding....
+MAP header|IP Packet|Optional padding|MAP header|Command Packet|Optional pad...
+
+3. Userspace configuration
+
+rmnet userspace configuration is done through netlink library librmnetctl
+and command line utility rmnetcli. Utility is hosted in codeaurora forum git.
+The driver uses rtnl_link_ops for communication.

-Stream Parser
--------------
+Stream Parser (strparser)
+
+Introduction
+============
 
 The stream parser (strparser) is a utility that parses messages of an
-application layer protocol running over a TCP connection. The stream
+application layer protocol running over a data stream. The stream
 parser works in conjunction with an upper layer in the kernel to provide
 kernel support for application layer messages. For instance, Kernel
 Connection Multiplexor (KCM) uses the Stream Parser to parse messages
 using a BPF program.
 
+The strparser works in one of two modes: receive callback or general
+mode.
+
+In receive callback mode, the strparser is called from the data_ready
+callback of a TCP socket. Messages are parsed and delivered as they are
+received on the socket.
+
+In general mode, a sequence of skbs are fed to strparser from an
+outside source. Message are parsed and delivered as the sequence is
+processed. This modes allows strparser to be applied to arbitrary
+streams of data.
+
 Interface
----------
+=========
 
 The API includes a context structure, a set of callbacks, utility
-functions, and a data_ready function. The callbacks include
-a parse_msg function that is called to perform parsing (e.g.
-BPF parsing in case of KCM), and a rcv_msg function that is called
-when a full message has been completed.
+functions, and a data_ready function for receive callback mode. The
+callbacks include a parse_msg function that is called to perform
+parsing (e.g.  BPF parsing in case of KCM), and a rcv_msg function
+that is called when a full message has been completed.
+
+Functions
+=========
+
+strp_init(struct strparser *strp, struct sock *sk,
+	  const struct strp_callbacks *cb)
+
+     Called to initialize a stream parser. strp is a struct of type
+     strparser that is allocated by the upper layer. sk is the TCP
+     socket associated with the stream parser for use with receive
+     callback mode; in general mode this is set to NULL. Callbacks
+     are called by the stream parser (the callbacks are listed below).
+
+void strp_pause(struct strparser *strp)
+
+     Temporarily pause a stream parser. Message parsing is suspended
+     and no new messages are delivered to the upper layer.
+
+void strp_pause(struct strparser *strp)
+
+     Unpause a paused stream parser.
+
+void strp_stop(struct strparser *strp);
+
+     strp_stop is called to completely stop stream parser operations.
+     This is called internally when the stream parser encounters an
+     error, and it is called from the upper layer to stop parsing
+     operations.
+
+void strp_done(struct strparser *strp);
+
+     strp_done is called to release any resources held by the stream
+     parser instance. This must be called after the stream processor
+     has been stopped.
 
-A stream parser can be instantiated for a TCP connection. This is done
-by:
+int strp_process(struct strparser *strp, struct sk_buff *orig_skb,
+		 unsigned int orig_offset, size_t orig_len,
+		 size_t max_msg_size, long timeo)
 
-strp_init(struct strparser *strp, struct sock *csk,
-	  struct strp_callbacks *cb)
+    strp_process is called in general mode for a stream parser to
+    parse an sk_buff. The number of bytes processed or a negative
+    error number is returned. Note that strp_process does not
+    consume the sk_buff. max_msg_size is maximum size the stream
+    parser will parse. timeo is timeout for completing a message.
 
-strp is a struct of type strparser that is allocated by the upper layer.
-csk is the TCP socket associated with the stream parser. Callbacks are
-called by the stream parser.
+void strp_data_ready(struct strparser *strp);
+
+    The upper layer calls strp_tcp_data_ready when data is ready on
+    the lower socket for strparser to process. This should be called
+    from a data_ready callback that is set on the socket. Note that
+    maximum messages size is the limit of the receive socket
+    buffer and message timeout is the receive timeout for the socket.
+
+void strp_check_rcv(struct strparser *strp);
+
+    strp_check_rcv is called to check for new messages on the socket.
+    This is normally called at initialization of a stream parser
+    instance or after strp_unpause.

----------
+Statistics
+==========
 
-The upper layer calls strp_tcp_data_ready when data is ready on the lower
-socket for strparser to process. This should be called from a data_ready
-callback that is set on the socket.
+Various counters are kept for each stream parser instance. These are in
+the strp_stats structure. strp_aggr_stats is a convenience structure for
+accumulating statistics for multiple stream parser instances.
+save_strp_stats and aggregate_strp_stats are helper functions to save
+and aggregate statistics.
 
-strp_stop is called to completely stop stream parser operations. This
-is called internally when the stream parser encounters an error, and
-it is called from the upper layer when unattaching a TCP socket.
+Message assembly limits
+=======================
 
-strp_done is called to unattach the stream parser from the TCP socket.
-This must be called after the stream processor has be stopped.
+The stream parser provide mechanisms to limit the resources consumed by
+message assembly.
 
-strp_check_rcv is called to check for new messages on the socket. This
-is normally called at initialization of the a stream parser instance
-of after strp_unpause.
+A timer is set when assembly starts for a new message. In receive
+callback mode the message timeout is taken from rcvtime for the
+associated TCP socket. In general mode, the timeout is passed as an
+argument in strp_process. If the timer fires before assembly completes
+the stream parser is aborted and the ETIMEDOUT error is set on the TCP
+socket if in receive callback mode.
 
-Statistics
-----------
+In receive callback mode, message length is limited to the receive
+buffer size of the associated TCP socket. If the length returned by
+parse_msg is greater than the socket buffer size then the stream parser
+is aborted with EMSGSIZE error set on the TCP socket. Note that this
+makes the maximum size of receive skbuffs for a socket with a stream
+parser to be 2*sk_rcvbuf of the TCP socket.

+ *
+ * Version: The version field is used to ensure backward compatibility
+ * going forward with future NSH specification updates.  It MUST be set
+ * to 0x0 by the sender, in this first revision of NSH.  Given the
+ * widespread implementation of existing hardware that uses the first
+ * nibble after an MPLS label stack for ECMP decision processing, this
+ * document reserves version 01b and this value MUST NOT be used in
+ * future versions of the protocol.  Please see [RFC7325] for further
+ * discussion of MPLS-related forwarding requirements.
+ *
+ * O bit: Setting this bit indicates an Operations, Administration, and
+ * Maintenance (OAM) packet.  The actual format and processing of SFC
+ * OAM packets is outside the scope of this specification (see for
+ * example [I-D.ietf-sfc-oam-framework] for one approach).
+ *
+ * The O bit MUST be set for OAM packets and MUST NOT be set for non-OAM
+ * packets.  The O bit MUST NOT be modified along the SFP.
+ *
+ * SF/SFF/SFC Proxy/Classifier implementations that do not support SFC
+ * OAM procedures SHOULD discard packets with O bit set, but MAY support
+ * a configurable parameter to enable forwarding received SFC OAM
+ * packets unmodified to the next element in the chain.  Forwarding OAM
+ * packets unmodified by SFC elements that do not support SFC OAM
+ * procedures may be acceptable for a subset of OAM functions, but can
+ * result in unexpected outcomes for others, thus it is recommended to
+ * analyze the impact of forwarding an OAM packet for all OAM functions
+ * prior to enabling this behavior.  The configurable parameter MUST be
+ * disabled by default.
+ *
+ * TTL: Indicates the maximum SFF hops for an SFP.  This field is used
+ * for service plane loop detection.  The initial TTL value SHOULD be
+ * configurable via the control plane; the configured initial value can
+ * be specific to one or more SFPs.  If no initial value is explicitly
+ * provided, the default initial TTL value of 63 MUST be used.  Each SFF
+ * involved in forwarding an NSH packet MUST decrement the TTL value by
+ * 1 prior to NSH forwarding lookup.  Decrementing by 1 from an incoming
+ * value of 0 shall result in a TTL value of 63.  The packet MUST NOT be
+ * forwarded if TTL is, after decrement, 0.
+ *
+ * All other flag fields, marked U, are unassigned and available for
+ * future use, see Section 11.2.1.  Unassigned bits MUST be set to zero
+ * upon origination, and MUST be ignored and preserved unmodified by
+ * other NSH supporting elements.  Elements which do not understand the
+ * meaning of any of these bits MUST NOT modify their actions based on
+ * those unknown bits.
+ *
+ * Length: The total length, in 4-byte words, of NSH including the Base
+ * Header, the Service Path Header, the Fixed Length Context Header or
+ * Variable Length Context Header(s).  The length MUST be 0x6 for MD
+ * Type equal to 0x1, and MUST be 0x2 or greater for MD Type equal to
+ * 0x2.  The length of the NSH header MUST be an integer multiple of 4
+ * bytes, thus variable length metadata is always padded out to a
+ * multiple of 4 bytes.
+ *
+ * MD Type: Indicates the format of NSH beyond the mandatory Base Header
+ * and the Service Path Header.  MD Type defines the format of the
+ * metadata being carried.
+ *
+ * 0x0 - This is a reserved value.  Implementations SHOULD silently
+ * discard packets with MD Type 0x0.
+ *
+ * 0x1 - This indicates that the format of the header includes a fixed
+ * length Context Header (see Figure 4 below).
+ *
+ * 0x2 - This does not mandate any headers beyond the Base Header and
+ * Service Path Header, but may contain optional variable length Context
+ * Header(s).  The semantics of the variable length Context Header(s)
+ * are not defined in this document.  The format of the optional
+ * variable length Context Headers is provided in Section 2.5.1.
+ *
+ * 0xF - This value is reserved for experimentation and testing, as per
+ * [RFC3692].  Implementations not explicitly configured to be part of
+ * an experiment SHOULD silently discard packets with MD Type 0xF.
+ *
+ * Next Protocol: indicates the protocol type of the encapsulated data.
+ * NSH does not alter the inner payload, and the semantics on the inner
+ * protocol remain unchanged due to NSH service function chaining.
+ * Please see the IANA Considerations section below, Section 11.2.5.
+ *
+ * This document defines the following Next Protocol values:
+ *
+ * 0x1: IPv4
+ * 0x2: IPv6
+ * 0x3: Ethernet
+ * 0x4: NSH
+ * 0x5: MPLS
+ * 0xFE: Experiment 1
+ * 0xFF: Experiment 2
+ *
+ * Packets with Next Protocol values not supported SHOULD be silently
+ * dropped by default, although an implementation MAY provide a
+ * configuration parameter to forward them.  Additionally, an
+ * implementation not explicitly configured for a specific experiment
+ * [RFC3692] SHOULD silently drop packets with Next Protocol values 0xFE
+ * and 0xFF.
+ *
+ * Service Path Identifier (SPI): Identifies a service path.
+ * Participating nodes MUST use this identifier for Service Function
+ * Path selection.  The initial classifier MUST set the appropriate SPI
+ * for a given classification result.
+ *
+ * Service Index (SI): Provides location within the SFP.  The initial
+ * classifier for a given SFP SHOULD set the SI to 255, however the
+ * control plane MAY configure the initial value of SI as appropriate
+ * (i.e., taking into account the length of the service function path).
+ * The Service Index MUST be decremented by a value of 1 by Service
+ * Functions or by SFC Proxy nodes after performing required services
+ * and the new decremented SI value MUST be used in the egress packet's
+ * NSH.  The initial Classifier MUST send the packet to the first SFF in
+ * the identified SFP for forwarding along an SFP.  If re-classification
+ * occurs, and that re-classification results in a new SPI, the
+ * (re)classifier is, in effect, the initial classifier for the
+ * resultant SPI.
+ *
+ * The SI is used in conjunction the with Service Path Identifier for
+ * Service Function Path Selection and for determining the next SFF/SF
+ * in the path.  The SI is also valuable when troubleshooting or
+ * reporting service paths.  Additionally, while the TTL field is the
+ * main mechanism for service plane loop detection, the SI can also be
+ * used for detecting service plane loops.
+ *
+ * When the Base Header specifies MD Type = 0x1, a Fixed Length Context
+ * Header (16-bytes) MUST be present immediately following the Service
+ * Path Header. The value of a Fixed Length Context
+ * Header that carries no metadata MUST be set to zero.
+ *
+ * When the base header specifies MD Type = 0x2, zero or more Variable
+ * Length Context Headers MAY be added, immediately following the
+ * Service Path Header (see Figure 5).  Therefore, Length = 0x2,
+ * indicates that only the Base Header followed by the Service Path
+ * Header are present.  The optional Variable Length Context Headers
+ * MUST be of an integer number of 4-bytes.  The base header Length
+ * field MUST be used to determine the offset to locate the original
+ * packet or frame for SFC nodes that require access to that
+ * information.

+ * Metadata Class (MD Class): Defines the scope of the 'Type' field to
+ * provide a hierarchical namespace.  The IANA Considerations
+ * Section 11.2.4 defines how the MD Class values can be allocated to
+ * standards bodies, vendors, and others.
+ *
+ * Type: Indicates the explicit type of metadata being carried.  The
+ * definition of the Type is the responsibility of the MD Class owner.
+ *
+ * Unassigned bit: One unassigned bit is available for future use. This
+ * bit MUST NOT be set, and MUST be ignored on receipt.
+ *
+ * Length: Indicates the length of the variable metadata, in bytes.  In
+ * case the metadata length is not an integer number of 4-byte words,
+ * the sender MUST add pad bytes immediately following the last metadata
+ * byte to extend the metadata to an integer number of 4-byte words.
+ * The receiver MUST round up the length field to the nearest 4-byte
+ * word boundary, to locate and process the next field in the packet.
+ * The receiver MUST access only those bytes in the metadata indicated
+ * by the length field (i.e., actual number of bytes) and MUST ignore
+ * the remaining bytes up to the nearest 4-byte word boundary.  The
+ * Length may be 0 or greater.
+ *
+ * A value of 0 denotes a Context Header without a Variable Metadata
+ * field.

+/* Devmaps primary use is as a backend map for XDP BPF helper call
+ * bpf_redirect_map(). Because XDP is mostly concerned with performance we
+ * spent some effort to ensure the datapath with redirect maps does not use
+ * any locking. This is a quick note on the details.
+ *
+ * We have three possible paths to get into the devmap control plane bpf
+ * syscalls, bpf programs, and driver side xmit/flush operations. A bpf syscall
+ * will invoke an update, delete, or lookup operation. To ensure updates and
+ * deletes appear atomic from the datapath side xchg() is used to modify the
+ * netdev_map array. Then because the datapath does a lookup into the netdev_map
+ * array (read-only) from an RCU critical section we use call_rcu() to wait for
+ * an rcu grace period before free'ing the old data structures. This ensures the
+ * datapath always has a valid copy. However, the datapath does a "flush"
+ * operation that pushes any pending packets in the driver outside the RCU
+ * critical section. Each bpf_dtab_netdev tracks these pending operations using
+ * an atomic per-cpu bitmap. The bpf_dtab_netdev object will not be destroyed
+ * until all bits are cleared indicating outstanding flush operations have
+ * completed.
+ *
+ * BPF syscalls may race with BPF program calls on any of the update, delete
+ * or lookup operations. As noted above the xchg() operation also keep the
+ * netdev_map consistent in this case. From the devmap side BPF programs
+ * calling into these operations are the same as multiple user space threads
+ * making system calls.
+ *
+ * Finally, any of the above may race with a netdev_unregister notifier. The
+ * unregister notifier must search for net devices in the map structure that
+ * contain a reference to the net device and remove them. This is a two step
+ * process (a) dereference the bpf_dtab_netdev object in netdev_map and (b)
+ * check to see if the ifindex is the same as the net_device being removed.
+ * When removing the dev a cmpxchg() is used to ensure the correct dev is
+ * removed, in the case of a concurrent update or delete operation it is
+ * possible that the initially referenced dev is no longer in the map. As the
+ * notifier hook walks the map we know that new dev references can not be
+ * added by the user because core infrastructure ensures dev_get_by_index()
+ * calls will fail at this point.

+/* Locking notes: Concurrent updates, deletes, and lookups are allowed and are

+ * complete. All operations operate on sock_map using cmpxchg and xchg
+ * operations to ensure we do not get stale references. Any reads into the
+ * map must be done with READ_ONCE() because of this.
+ *
+ * A psock is destroyed via call_rcu and after any worker threads are cancelled
+ * and syncd so we are certain all references from the update/lookup/delete
+ * operations as well as references in the data path are no longer in use.
+ *
+ * Psocks may exist in multiple maps, but only a single set of parse/verdict
+ * programs may be inherited from the maps it belongs to. A reference count
+ * is kept with the total number of references to the psock from all maps. The
+ * psock will not be released until this reaches zero. The psock and sock
+ * user data data use the sk_callback_lock to protect critical data structures
+ * from concurrent access. This allows us to avoid two updates from modifying
+ * the user data in sock and the lock is required anyways for modifying
+ * callbacks, we simply increase its scope slightly.
+ *
+ * Rules to follow,
+ *  - psock must always be read inside RCU critical section
+ *  - sk_user_data must only be modified inside sk_callback_lock and read
+ *    inside RCU critical section.
+ *  - psock->maps list must only be read & modified inside sk_callback_lock
+ *  - sock_map must use READ_ONCE and (cmp)xchg operations
+ *  - BPF verdict/parse programs must use READ_ONCE and xchg operations

+ * or VMADDR_CID_HOST (both are equivalent) as the remote cid, and when we
+ * write apps to bind() & listen() in the VM, we can only use VMADDR_CID_ANY
+ * as the local cid.
+ *
+ * On the host, Hyper-V Sockets are supported by Winsock AF_HYPERV:

+ * guide/make-integration-service, and the endpoint is <VmID, ServiceId> with

+ * {

+ *    USHORT Reserved;
+ *    GUID VmId;

+ * VMBus, because here it's obvious the host and the VM can easily identify
+ * each other. Though the VmID is useful on the host, especially in the case
+ * of Windows container, Linux VM doesn't need it at all.
+ *
+ * To make use of the AF_VSOCK infrastructure in Linux VM, we have to limit
+ * the available GUID space of SOCKADDR_HV so that we can create a mapping
+ * between AF_VSOCK port and SOCKADDR_HV Service GUID. The rule of writing
+ * Hyper-V Sockets apps on the host and in Linux VM is:
+ *
+ ****************************************************************************
+ * The only valid Service GUIDs, from the perspectives of both the host and *
+ * Linux VM, that can be connected by the other end, must conform to this   *
+ * format: <port>-facb-11e6-bd58-64006a7986d3, and the "port" must be in    *
+ * this range [0, 0x7FFFFFFF].                                              *
+ ****************************************************************************
+ *
+ * When we write apps on the host to connect(), the GUID ServiceID is used.
+ * When we write apps in Linux VM to connect(), we only need to specify the
+ * port and the driver will form the GUID and use that to request the host.
+ *
+ * From the perspective of Linux VM:
+ * 1. the local ephemeral port (i.e. the local auto-bound port when we call
+ * connect() without explicit bind()) is generated by __vsock_bind_stream(),
+ * and the range is [1024, 0xFFFFFFFF).
+ * 2. the remote ephemeral port (i.e. the auto-generated remote port for
+ * a connect request initiated by the host's connect()) is generated by
+ * hvs_remote_addr_init() and the range is [0x80000000, 0xFFFFFFFF).

-#
-# Usage:
-# - After configured vSwitch and vNIC with SRIOV, start Linux virtual
-#   machine (VM)
-# - Run this scripts on the VM. It will create configuration files in
-#   distro specific directory.
-# - Reboot the VM, so that the bonding config are enabled.
-#
-# The config files are DHCP by default. You may edit them if you need to change
-# to Static IP or change other settings.
