Linux CAIF
===========
copyright (C) ST-Ericsson AB 2010
Author: Sjur Brendeland/ sjur.brandeland@stericsson.com
License terms: GNU General Public License (GPL) version 2
Introduction
------------
CAIF is a MUX protocol used by ST-Ericsson cellular modems for
communication between Modem and host. The host processes can open virtual AT
channels, initiate GPRS Data connections, Video channels and Utility Channels.
The Utility Channels are general purpose pipes between modem and host.
ST-Ericsson modems support a number of transports between modem
and host. Currently, UART and Loopback are available for Linux.
Architecture:
------------
The implementation of CAIF is divided into:
* CAIF Socket Layer, Kernel API, and Net Device.
* CAIF Core Protocol Implementation
* CAIF Link Layer, implemented as NET devices.

Using the Kernel API
----------------------
The Kernel API is used for accessing CAIF channels from the
kernel.
The user of the API has to implement two callbacks for receive
and control.
The receive callback gives a CAIF packet as a SKB. The control
callback will
notify of channel initialization complete, and flow-on/flow-
off.
struct caif_device caif_dev = {
.caif_config = {
.name = "MYDEV"
.type = CAIF_CHTY_AT
}
.receive_cb = my_receive,
.control_cb = my_control,
};
caif_add_device(&caif_dev);
caif_transmit(&caif_dev, skb);
See the caif_kernel.h for details about the CAIF kernel API.

===========================
===========================
CAIF Core Protocol Layer
=========================================
CAIF Core layer implements the CAIF protocol as defined by ST-Ericsson.
It implements the CAIF protocol stack in a layered approach, where
each layer described in the specification is implemented as a separate layer.
The architecture is inspired by the design patterns "Protocol Layer" and
"Protocol Packet".
== CAIF structure ==
The Core CAIF implementation contains:
- Simple implementation of CAIF.
- Layered architecture (a la Streams), each layer in the CAIF
specification is implemented in a separate c-file.
- Clients must implement PHY layer to access physical HW
with receive and transmit functions.
- Clients must call configuration function to add PHY layer.
- Clients must implement CAIF layer to consume/produce
CAIF payload with receive and transmit functions.
- Clients must call configuration function to add and connect the
Client layer.
- When receiving / transmitting CAIF Packets (cfpkt), ownership is passed
to the called function (except for framing layers' receive functions
or if a transmit function returns an error, in which case the caller
must free the packet).
Layered Architecture
--------------------
The CAIF protocol can be divided into two parts: Support functions and Protocol
Implementation. The support functions include:
- CFPKT CAIF Packet. Implementation of CAIF Protocol Packet. The
CAIF Packet has functions for creating, destroying and adding content
and for adding/extracting header and trailers to protocol packets.
- CFLST CAIF list implementation.
- CFGLUE CAIF Glue. Contains OS Specifics, such as memory
allocation, endianness, etc.
The CAIF Protocol implementation contains:
- CFCNFG CAIF Configuration layer. Configures the CAIF Protocol
Stack and provides a Client interface for adding Link-Layer and
Driver interfaces on top of the CAIF Stack.
- CFCTRL CAIF Control layer. Encodes and Decodes control messages
such as enumeration and channel setup. Also matches request and
response messages.
- CFSERVL General CAIF Service Layer functionality; handles flow
control and remote shutdown requests.
- CFVEI CAIF VEI layer. Handles CAIF AT Channels on VEI (Virtual
External Interface). This layer encodes/decodes VEI frames.
- CFDGML CAIF Datagram layer. Handles CAIF Datagram layer (IP
traffic), encodes/decodes Datagram frames.
- CFMUX CAIF Mux layer. Handles multiplexing between multiple
physical bearers and multiple channels such as VEI, Datagram, etc.
The MUX keeps track of the existing CAIF Channels and
Physical Instances and selects the apropriate instance based
on Channel-Id and Physical-ID.
- CFFRML CAIF Framing layer. Handles Framing i.e. Frame length
and frame checksum.
- CFSERL CAIF Serial layer. Handles concatenation/split of frames
into CAIF Frames with correct length.

In this layered approach the following "rules" apply.
- All layers embed the same structure "struct cflayer"
- A layer does not depend on any other layer's private data.
- Layers are stacked by setting the pointers
layer->up , layer->dn
- In order to send data upwards, each layer should do
layer->up->receive(layer->up, packet);
- In order to send data downwards, each layer should do
layer->dn->transmit(layer->dn, packet);
Linux Driver Implementation
===========================
Linux GPRS Net Device and CAIF socket are implemented on top of the
CAIF Core protocol. The Net device and CAIF socket have an instance of
'struct cflayer', just like the CAIF Core protocol stack.
Net device and Socket implement the 'receive()' function defined by
'struct cflayer', just like the rest of the CAIF stack. In this way, transmit and
receive of packets is handled as by the rest of the layers: the 'dn->transmit()'
function is called in order to transmit data.
The layer on top of the CAIF Core implementation is
sometimes referred to as the "Client layer".
Configuration of Link Layer
---------------------------
The Link Layer is implemented as Linux net devices (struct net_device).
Payload handling and registration is done using standard Linux mechanisms.
The CAIF Protocol relies on a loss-less link layer without implementing
retransmission. This implies that packet drops must not happen.
Therefore a flow-control mechanism is implemented where the physical
interface can initiate flow stop for all CAIF Channels.

=== Start ===
If you have compiled CAIF for modules do:
$modprobe crc_ccitt
$modprobe caif
$modprobe caif_socket
$modprobe chnl_net
=== Preparing the setup with a STE modem ===
If you are working on integration of CAIF you should make sure
that the kernel is built with module support.
There are some things that need to be tweaked to get the host TTY correctly
set up to talk to the modem.
Since the CAIF stack is running in the kernel and we want to use the existing
TTY, we are installing our physical serial driver as a line discipline above
the TTY device.
To achieve this we need to install the N_CAIF ldisc from user space.
The benefit is that we can hook up to any TTY.
The use of Start-of-frame-extension (STX) must also be set as
module parameter "ser_use_stx".
Normally Frame Checksum is always used on UART, but this is also provided as a
module parameter "ser_use_fcs".
$ modprobe caif_serial ser_ttyname=/dev/ttyS0 ser_use_stx=yes
$ ifconfig caif_ttyS0 up
PLEASE NOTE: There is a limitation in Android shell.
It only accepts one argument to insmod/modprobe!
=== Trouble shooting ===
There are debugfs parameters provided for serial communication.
/sys/kernel/debug/caif_serial/<tty-name>/
* ser_state: Prints the bit-mask status where
- 0x02 means SENDING, this is a transient state.
- 0x10 means FLOW_OFF_SENT, i.e. the previous frame has not been sent
and is blocking further send operation. Flow OFF has been propagated
to all CAIF Channels using this TTY.
* tty_status: Prints the bit-mask tty status information
- 0x01 - tty->warned is on.
- 0x02 - tty->low_latency is on.
- 0x04 - tty->packed is on.
- 0x08 - tty->flow_stopped is on.
- 0x10 - tty->hw_stopped is on.
- 0x20 - tty->stopped is on.
* last_tx_msg: Binary blob Prints the last transmitted frame.
This can be printed with
$od --format=x1 /sys/kernel/debug/caif_serial/<tty>/last_rx_msg.
The first two tx messages sent look like this. Note: The initial
byte 02 is start of frame extension (STX) used for re-syncing
upon errors.
- Enumeration:
0000000 02 05 00 00 03 01 d2 02
| | | | | |
STX(1) | | | |
Length(2)| | |
Control Channel(1)
Command:Enumeration(1)
Link-ID(1)
Checksum(2)
- Channel Setup:
0000000 02 07 00 00 00 21 a1 00 48 df
| | | | | | | |
STX(1) | | | | | |
Length(2)| | | | |
Control Channel(1)
Command:Channel Setup(1)
Channel Type(1)
Priority and Link-ID(1)
Endpoint(1)
Checksum(2)
* last_rx_msg: Prints the last transmitted frame.
The RX messages for LinkSetup look almost identical but they have the
bit 0x20 set in the command bit, and Channel Setup has added one byte
before Checksum containing Channel ID.
NOTE: Several CAIF Messages might be concatenated. The maximum debug
buffer size is 128 bytes.
== Error Scenarios:
- last_tx_msg contains channel setup message and last_rx_msg is empty ->
The host seems to be able to send over the UART, at least the CAIF ldisc get
notified that sending is completed.
- last_tx_msg contains enumeration message and last_rx_msg is empty ->
The host is not able to send the message from UART, the tty has not been
able to complete the transmit operation.
- if /sys/kernel/debug/caif_serial/<tty>/tty_status is non-zero there
might be problems transmitting over UART.
E.g. host and modem wiring is not correct you will typically see
tty_status = 0x10 (hw_stopped) and ser_state = 0x10 (FLOW_OFF_SENT).
You will probably see the enumeration message in last_tx_message
and empty last_rx_message.

This document describes how to use the kernel's L2TP drivers to
provide L2TP functionality. L2TP is a protocol that tunnels one or
more sessions over an IP tunnel. It is commonly used for VPNs
(L2TP/IPSec) and by ISPs to tunnel subscriber PPP sessions over an IP

network infrastructure. With L2TPv3, it is also useful as a Layer-2
tunneling infrastructure.
Features
========
L2TPv2 (PPP over L2TP (UDP tunnels)).
L2TPv3 ethernet pseudowires.
L2TPv3 PPP pseudowires.
L2TPv3 IP encapsulation.
Netlink sockets for L2TPv3 configuration management.
History
=======
The original pppol2tp driver was introduced in 2.6.23 and provided
L2TPv2 functionality (rfc2661). L2TPv2 is used to tunnel one or more PPP
sessions over a UDP tunnel.
L2TPv3 (rfc3931) changes the protocol to allow different frame types
to be passed over an L2TP tunnel by moving the PPP-specific parts of
the protocol out of the core L2TP packet headers. Each frame type is
known as a pseudowire type. Ethernet, PPP, HDLC, Frame Relay and ATM
pseudowires for L2TP are defined in separate RFC standards. Another
change for L2TPv3 is that it can be carried directly over IP with no
UDP header (UDP is optional). It is also possible to create static
unmanaged L2TPv3 tunnels manually without a control protocol
(userspace daemon) to manage them.
To support L2TPv3, the original pppol2tp driver was split up to
separate the L2TP and PPP functionality. Existing L2TPv2 userspace
apps should be unaffected as the original pppol2tp sockets API is
retained. L2TPv3, however, uses netlink to manage L2TPv3 tunnels and
sessions.
Design
======
The PPPoL2TP driver, drivers/net/pppol2tp.c, provides a mechanism by
which PPP frames carried through an L2TP session are passed through
the kernel's PPP subsystem. The standard PPP daemon, pppd, handles all
PPP interaction with the peer. PPP network interfaces are created for
each local PPP endpoint.
The L2TP protocol separates control and data frames. The L2TP kernel
drivers handle only L2TP data frames; control frames are always
handled by userspace. L2TP control frames carry messages between L2TP
clients/servers and are used to setup / teardown tunnels and
sessions. An L2TP client or server is implemented in userspace.
The L2TP protocol http://www.faqs.org/rfcs/rfc2661.html defines L2TP
control and data frames. L2TP control frames carry messages between
L2TP clients/servers and are used to setup / teardown tunnels and
sessions. An L2TP client or server is implemented in userspace and
will use a regular UDP socket per tunnel. L2TP data frames carry PPP
frames, which may be PPP control or PPP data. The kernel's PPP
Each L2TP tunnel is implemented using a UDP or L2TPIP socket; L2TPIP
provides L2TPv3 IP encapsulation (no UDP) and is implemented using a
new l2tpip socket family. The tunnel socket is typically created by
userspace, though for unmanaged L2TPv3 tunnels, the socket can also be
created by the kernel. Each L2TP session (pseudowire) gets a network
interface instance. In the case of PPP, these interfaces are created
indirectly by pppd using a pppol2tp socket. In the case of ethernet,
the netdevice is created upon a netlink request to create an L2TPv3
ethernet pseudowire.
For PPP, the PPPoL2TP driver, net/l2tp/l2tp_ppp.c, provides a
mechanism by which PPP frames carried through an L2TP session are
passed through the kernel's PPP subsystem. The standard PPP daemon,
pppd, handles all PPP interaction with the peer. PPP network
interfaces are created for each local PPP endpoint. The kernel's PPP
subsystem arranges for PPP control frames to be delivered to pppd,
while data frames are forwarded as usual.
For ethernet, the L2TPETH driver, net/l2tp/l2tp_eth.c, implements a
netdevice driver, managing virtual ethernet devices, one per
pseudowire. These interfaces can be managed using standard Linux tools
such as "ip" and "ifconfig". If only IP frames are passed over the
tunnel, the interface can be given an IP addresses of itself and its
peer. If non-IP frames are to be passed over the tunnel, the interface
can be added to a bridge using brctl. All L2TP datapath protocol
functions are handled by the L2TP core driver.
Each tunnel and session within a tunnel is assigned a unique tunnel_id
and session_id. These ids are carried in the L2TP header of every
control and data packet. The pppol2tp driver uses them to lookup
internal tunnel and/or session contexts. Zero tunnel / session ids are
treated specially - zero ids are never assigned to tunnels or sessions
in the network. In the driver, the tunnel context keeps a pointer to
the tunnel UDP socket. The session context keeps a pointer to the
PPPoL2TP socket, as well as other data that lets the driver interface
to the kernel PPP subsystem.
control and data packet. (Actually, in L2TPv3, the tunnel_id isn't
present in data frames - it is inferred from the IP connection on
which the packet was received.) The L2TP driver uses the ids to lookup
internal tunnel and/or session contexts to determine how to handle the
packet. Zero tunnel / session ids are treated specially - zero ids are
never assigned to tunnels or sessions in the network. In the driver,
the tunnel context keeps a reference to the tunnel UDP or L2TPIP
socket. The session context holds data that lets the driver interface
to the kernel's network frame type subsystems, i.e. PPP, ethernet.
Note that the pppol2tp kernel driver handles only L2TP data frames;
L2TP control frames are simply passed up to userspace in the UDP
tunnel socket. The kernel handles all datapath aspects of the
protocol, including data packet resequencing (if enabled).

include/linux/l2tp.h to manage tunnel and session contexts. The
general procedure to create a new L2TP tunnel with one session is:-
1. Open a GENL socket using L2TP_GENL_NAME for configuring the kernel
using netlink.
2. Create a UDP or L2TPIP socket for the tunnel.
3. Create a new L2TP tunnel using a L2TP_CMD_TUNNEL_CREATE
request. Set attributes according to desired tunnel parameters,
referencing the UDP or L2TPIP socket created in the previous step.
4. Create a new L2TP session in the tunnel using a
L2TP_CMD_SESSION_CREATE request.
The tunnel and all of its sessions are closed when the tunnel socket
is closed. The netlink API may also be used to delete sessions and
tunnels. Configuration and status info may be set or read using netlink.
The L2TP driver also supports static (unmanaged) L2TPv3 tunnels. These
are where there is no L2TP control message exchange with the peer to
setup the tunnel; the tunnel is configured manually at each end of the
tunnel. There is no need for an L2TP userspace application in this
case -- the tunnel socket is created by the kernel and configured
using parameters sent in the L2TP_CMD_TUNNEL_CREATE netlink
request. The "ip" utility of iproute2 has commands for managing static
L2TPv3 tunnels; do "ip l2tp help" for more information.

If enabled, files under a l2tp debugfs directory can be used to dump
kernel state about L2TP tunnels and sessions. To access it, the
debugfs filesystem must first be mounted.
# mount -t debugfs debugfs /debug
Files under the l2tp directory can then be accessed.
# cat /debug/l2tp/tunnels
The debugfs files should not be used by applications to obtain L2TP
state information because the file format is subject to change. It is
implemented to provide extra debug information to help diagnose
problems.) Users should use the netlink API.
/proc/net/pppol2tp is also provided for backwards compaibility with
the original pppol2tp driver. It lists information about L2TPv2
tunnels and sessions only. Its use is discouraged.
Unmanaged L2TPv3 Tunnels
========================
Some commercial L2TP products support unmanaged L2TPv3 ethernet
tunnels, where there is no L2TP control protocol; tunnels are
configured at each side manually. New commands are available in
iproute2's ip utility to support this.
To create an L2TPv3 ethernet pseudowire between local host 192.168.1.1
and peer 192.168.1.2, using IP addresses 10.5.1.1 and 10.5.1.2 for the
tunnel endpoints:-
# modprobe l2tp_eth
# modprobe l2tp_netlink
# ip l2tp add tunnel tunnel_id 1 peer_tunnel_id 1 udp_sport 5000 \
udp_dport 5000 encap udp local 192.168.1.1 remote 192.168.1.2
# ip l2tp add session tunnel_id 1 session_id 1 peer_session_id 1
# ifconfig -a
# ip addr add 10.5.1.2/32 peer 10.5.1.1/32 dev l2tpeth0
# ifconfig l2tpeth0 up
Choose IP addresses to be the address of a local IP interface and that
of the remote system. The IP addresses of the l2tpeth0 interface can be
anything suitable.
Repeat the above at the peer, with ports, tunnel/session ids and IP
addresses reversed. The tunnel and session IDs can be any non-zero
32-bit number, but the values must be reversed at the peer.
Host 1 Host2
udp_sport=5000 udp_sport=5001
udp_dport=5001 udp_dport=5000
tunnel_id=42 tunnel_id=45
peer_tunnel_id=45 peer_tunnel_id=42
session_id=128 session_id=5196755
peer_session_id=5196755 peer_session_id=128
When done at both ends of the tunnel, it should be possible to send
data over the network. e.g.
# ping 10.5.1.1

Internal Implementation
=======================
The PPPoL2TP driver was developed as part of the OpenL2TP project by
The driver keeps a struct l2tp_tunnel context per L2TP tunnel and a
struct l2tp_session context for each session. The l2tp_tunnel is
always associated with a UDP or L2TP/IP socket and keeps a list of
sessions in the tunnel. The l2tp_session context keeps kernel state
about the session. It has private data which is used for data specific
to the session type. With L2TPv2, the session always carried PPP
traffic. With L2TPv3, the session can also carry ethernet frames
(ethernet pseudowire) or other data types such as ATM, HDLC or Frame
Relay.
When a tunnel is first opened, the reference count on the socket is
increased using sock_hold(). This ensures that the kernel socket
cannot be removed while L2TP's data structures reference it.
Some L2TP sessions also have a socket (PPP pseudowires) while others
do not (ethernet pseudowires). We can't use the socket reference count
as the reference count for session contexts. The L2TP implementation
therefore has its own internal reference counts on the session
contexts.
To Do
=====
Add L2TP tunnel switching support. This would route tunneled traffic
from one L2TP tunnel into another. Specified in
http://tools.ietf.org/html/draft-ietf-l2tpext-tunnel-switching-08
Add L2TPv3 VLAN pseudowire support.
Add L2TPv3 IP pseudowire support.
Add L2TPv3 ATM pseudowire support.
Miscellaneous
=============
The L2TP drivers were developed as part of the OpenL2TP project by
Katalix Systems Ltd. OpenL2TP is a full-featured L2TP client / server,
designed from the ground up to have the L2TP datapath in the
kernel. The project also implemented the pppol2tp plugin for pppd
which allows pppd to use the kernel driver. Details can be found at
http://openl2tp.sourceforge.net.

After an application opens /dev/rfkill, it can read the current state of all
