INTRODUCTION
|
||||
|
||||
lwIP is a small independent implementation of the TCP/IP protocol
|
||||
suite that has been developed by Adam Dunkels at the Computer and
|
||||
Networks Architectures (CNA) lab at the Swedish Institute of Computer
|
||||
Science (SICS).
|
||||
|
||||
The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
|
||||
while still having a full scale TCP. This making lwIP suitable for use
|
||||
in embedded systems with tens of kilobytes of free RAM and room for
|
||||
around 40 kilobytes of code ROM.
|
||||
|
||||
FEATURES
|
||||
|
||||
* IP (Internet Protocol) including packet forwarding over multiple network
|
||||
interfaces
|
||||
* ICMP (Internet Control Message Protocol) for network maintenance and debugging
|
||||
* IGMP (Internet Group Management Protocol) for multicast traffic management
|
||||
* UDP (User Datagram Protocol) including experimental UDP-lite extensions
|
||||
* TCP (Transmission Control Protocol) with congestion control, RTT estimation
|
||||
and fast recovery/fast retransmit
|
||||
* Specialized raw/native API for enhanced performance
|
||||
* Optional Berkeley-like socket API
|
||||
* DNS (Domain names resolver)
|
||||
* SNMP (Simple Network Management Protocol)
|
||||
* DHCP (Dynamic Host Configuration Protocol)
|
||||
* AUTOIP (for IPv4, conform with RFC 3927)
|
||||
* PPP (Point-to-Point Protocol)
|
||||
* ARP (Address Resolution Protocol) for Ethernet

||||
DEVELOPMENT
|
||||
|
||||
lwIP has grown into an excellent TCP/IP stack for embedded devices,
|
||||
and developers using the stack often submit bug fixes, improvements,
|
||||
and additions to the stack to further increase its usefulness.
|
||||
|
||||
Development of lwIP is hosted on Savannah, a central point for
|
||||
software development, maintenance and distribution. Everyone can
|
||||
help improve lwIP by use of Savannah's interface, Git and the
|
||||
mailing list. A core team of developers will commit changes to the
|
||||
Git source tree.
|
||||
|
||||
The lwIP TCP/IP stack is maintained in the 'lwip' Git module and
|
||||
contributions (such as platform ports) are in the 'contrib' Git module.
|
||||
|
||||
See doc/savannah.txt for details on Git server access for users and
|
||||
developers.
|
||||
|
||||
The current Git trees are web-browsable:
|
||||
http://git.savannah.gnu.org/cgit/lwip.git
|
||||
http://git.savannah.gnu.org/cgit/lwip/lwip-contrib.git
|
||||
|
||||
Submit patches and bugs via the lwIP project page:
|
||||
http://savannah.nongnu.org/projects/lwip/
|
||||
|
||||
|
||||
DOCUMENTATION
|
||||
|
||||
The original out-dated homepage of lwIP and Adam Dunkels' papers on
|
||||
lwIP are at the official lwIP home page:
|
||||
http://www.sics.se/~adam/lwip/
|
||||
|
||||
Self documentation of the source code is regularly extracted from the
|
||||
current Git sources and is available from this web page:
|
||||
http://www.nongnu.org/lwip/
|
||||
|
||||
There is now a constantly growin wiki about lwIP at
|
||||
http://lwip.wikia.com/wiki/LwIP_Wiki
|
||||
|
||||
Also, there are mailing lists you can subscribe at
|
||||
http://savannah.nongnu.org/mail/?group=lwip
|
||||
plus searchable archives:
|
||||
http://lists.nongnu.org/archive/html/lwip-users/
|
||||
http://lists.nongnu.org/archive/html/lwip-devel/
|
||||
|
||||
Reading Adam's papers, the files in docs/, browsing the source code
|
||||
documentation and browsing the mailing list archives is a good way to
|
||||
become familiar with the design of lwIP.

This file lists major changes between release versions that require
|
||||
ports or applications to be changed. Use it to update a port or an
|
||||
application written for an older version of lwIP to correctly work
|
||||
with newer versions.
|
||||
|
||||
|
||||
(git master)
|
||||
|
||||
* [Enter new changes just after this line - do not remove this line]
|
||||
|
||||
* TODO
|
||||
|
||||
(1.4.0)
|
||||
|
||||
++ Application changes:
|
||||
|
||||
* Replaced struct ip_addr by typedef ip_addr_t (struct ip_addr is kept for
|
||||
compatibility to old applications, but will be removed in the future).
|
||||
|
||||
* Renamed mem_realloc() to mem_trim() to prevent confusion with realloc()
|
||||
|
||||
+++ Raw API:
|
||||
* Changed the semantics of tcp_close() (since it was rather a
|
||||
shutdown before): Now the application does *NOT* get any calls to the recv
|
||||
callback (aside from NULL/closed) after calling tcp_close()
|
||||
|
||||
* When calling tcp_abort() from a raw API TCP callback function,
|
||||
make sure you return ERR_ABRT to prevent accessing unallocated memory.
|
||||
(ERR_ABRT now means the applicaiton has called tcp_abort!)
|
||||
|
||||
+++ Netconn API:
|
||||
* Changed netconn_receive() and netconn_accept() to return
|
||||
err_t, not a pointer to new data/netconn.
|
||||
|
||||
+++ Socket API:
|
||||
* LWIP_SO_RCVTIMEO: when accept() or recv() time out, they
|
||||
now set errno to EWOULDBLOCK/EAGAIN, not ETIMEDOUT.
|
||||
|
||||
* Added a minimal version of posix fctl() to have a
|
||||
standardised way to set O_NONBLOCK for nonblocking sockets.
|
||||
|
||||
+++ all APIs:
|
||||
* correctly implemented SO(F)_REUSEADDR
|
||||
|
||||
++ Port changes
|
||||
|
||||
+++ new files:
|
||||
|
||||
* Added 4 new files: def.c, timers.c, timers.h, tcp_impl.h:
|
||||
|
||||
* Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains
|
||||
the actual application programmer's API
|
||||
|
||||
* Separated timer implementation from sys.h/.c, moved to timers.h/.c;
|
||||
Added timer implementation for NO_SYS==1, set NO_SYS_NO_TIMERS==1 if you
|
||||
still want to use your own timer implementation for NO_SYS==0 (as before).
|
||||
|
||||
+++ sys layer:
|
||||
|
||||
* Converted mbox- and semaphore-functions to take pointers to sys_mbox_t/
|
||||
sys_sem_t;
|
||||
|
||||
* Converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
|
||||
|
||||
* Added Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use
|
||||
binary semaphores instead of mutexes - as before)
|
||||
|
||||
+++ new options:
|
||||
|
||||
* Don't waste memory when chaining segments, added option TCP_OVERSIZE to
|
||||
prevent creating many small pbufs when calling tcp_write with many small
|
||||
blocks of data. Instead, pbufs are allocated larger than needed and the
|
||||
space is used for later calls to tcp_write.
|
||||
|
||||
* Added LWIP_NETIF_TX_SINGLE_PBUF to always copy to try to create single pbufs
|
||||
in tcp_write/udp_send.
|
||||
|
||||
* Added an additional option LWIP_ETHERNET to support ethernet without ARP
|
||||
(necessary for pure PPPoE)
|
||||
|
||||
* Add MEMP_SEPARATE_POOLS to place memory pools in separate arrays. This may
|
||||
be used to place these pools into user-defined memory by using external
|
||||
declaration.
|
||||
|
||||
* Added TCP_SNDQUEUELOWAT corresponding to TCP_SNDLOWAT
|
||||
|
||||
+++ new pools:
|
||||
|
||||
* Netdb uses a memp pool for allocating memory when getaddrinfo() is called,
|
||||
so MEMP_NUM_NETDB has to be set accordingly.
|
||||
|
||||
* DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses a memp pool instead of the heap, so
|
||||
MEMP_NUM_LOCALHOSTLIST has to be set accordingly.
|
||||
|
||||
* Snmp-agent uses a memp pools instead of the heap, so MEMP_NUM_SNMP_* have
|
||||
to be set accordingly.
|
||||
|
||||
* PPPoE uses a MEMP pool instead of the heap, so MEMP_NUM_PPPOE_INTERFACES
|
||||
has to be set accordingly
|
||||
|
||||
* Integrated loopif into netif.c - loopif does not have to be created by the
|
||||
port any more, just define LWIP_HAVE_LOOPIF to 1.
|
||||
|
||||
* Added define LWIP_RAND() for lwip-wide randomization (needs to be defined
|
||||
in cc.h, e.g. used by igmp)
|
||||
|
||||
* Added printf-formatter X8_F to printf u8_t as hex
|
||||
|
||||
* The heap now may be moved to user-defined memory by defining
|
||||
LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
|
||||
|
||||
* added autoip_set_struct() and dhcp_set_struct() to let autoip and dhcp work
|
||||
with user-allocated structs instead of calling mem_malloc
|
||||
|
||||
* Added const char* name to mem- and memp-stats for easier debugging.
|
||||
|
||||
* Calculate the TCP/UDP checksum while copying to only fetch data once:
|
||||
Define LWIP_CHKSUM_COPY to a memcpy-like function that returns the checksum
|
||||
|
||||
* Added SO_REUSE_RXTOALL to pass received UDP broadcast/multicast packets to
|
||||
more than one pcb.
|
||||
|
||||
* Changed the semantics of ARP_QUEUEING==0: ARP_QUEUEING now cannot be turned
|
||||
off any more, if this is set to 0, only one packet (the most recent one) is
|
||||
queued (like demanded by RFC 1122).
|
||||
|
||||
|
||||
++ Major bugfixes/improvements
|
||||
|
||||
* Implemented tcp_shutdown() to only shut down one end of a connection
|
||||
* Implemented shutdown() at socket- and netconn-level
|
||||
* Added errorset support to select() + improved select speed overhead
|
||||
* Merged pppd to v2.3.11 (including some backported bugfixes from 2.4.x)
|
||||
* Added timer implementation for NO_SYS==1 (may be disabled with NO_SYS_NO_TIMERS==1
|
||||
* Use macros defined in ip_addr.h to work with IP addresses
|
||||
* Implemented many nonblocking socket/netconn functions
|
||||
* Fixed ARP input processing: only add a new entry if a request was directed as us
|
||||
* mem_realloc() to mem_trim() to prevent confusion with realloc()
|
||||
* Some improvements for AutoIP (don't route/forward link-local addresses, don't break
|
||||
existing connections when assigning a routable address)
|
||||
* Correctly handle remote side overrunning our rcv_wnd in ooseq case
|
||||
* Removed packing from ip_addr_t, the packed version is now only used in protocol headers
|
||||
* Corrected PBUF_POOL_BUFSIZE for ports where ETH_PAD_SIZE > 0
|
||||
* Added support for static ARP table entries
|
||||
|
||||

1 Introduction
|
||||
|
||||
This document describes some guidelines for people participating
|
||||
in lwIP development.
|
||||
|
||||
2 How to contribute to lwIP
|
||||
|
||||
Here is a short list of suggestions to anybody working with lwIP and
|
||||
trying to contribute bug reports, fixes, enhancements, platform ports etc.
|
||||
First of all as you may already know lwIP is a volunteer project so feedback
|
||||
to fixes or questions might often come late. Hopefully the bug and patch tracking
|
||||
features of Savannah help us not lose users' input.
|
||||
|
||||
2.1 Source code style:
|
||||
|
||||
1. do not use tabs.
|
||||
2. indentation is two spaces per level (i.e. per tab).
|
||||
3. end debug messages with a trailing newline (\n).
|
||||
4. one space between keyword and opening bracket.
|
||||
5. no space between function and opening bracket.
|
||||
6. one space and no newline before opening curly braces of a block.
|
||||
7. closing curly brace on a single line.
|
||||
8. spaces surrounding assignment and comparisons.
|
||||
9. don't initialize static and/or global variables to zero, the compiler takes care of that.
|
||||
10. use current source code style as further reference.
|
||||
|
||||
2.2 Source code documentation style:
|
||||
|
||||
1. JavaDoc compliant and Doxygen compatible.
|
||||
2. Function documentation above functions in .c files, not .h files.
|
||||
(This forces you to synchronize documentation and implementation.)
|
||||
3. Use current documentation style as further reference.
|
||||
|
||||
2.3 Bug reports and patches:
|
||||
|
||||
1. Make sure you are reporting bugs or send patches against the latest
|
||||
sources. (From the latest release and/or the current Git sources.)
|
||||
2. If you think you found a bug make sure it's not already filed in the
|
||||
bugtracker at Savannah.
|
||||
3. If you have a fix put the patch on Savannah. If it is a patch that affects
|
||||
both core and arch specific stuff please separate them so that the core can
|
||||
be applied separately while leaving the other patch 'open'. The prefered way
|
||||
is to NOT touch archs you can't test and let maintainers take care of them.
|
||||
This is a good way to see if they are used at all - the same goes for unix
|
||||
netifs except tapif.
|
||||
4. Do not file a bug and post a fix to it to the patch area. Either a bug report
|
||||
or a patch will be enough.
|
||||
If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area.
|
||||
5. Patches should be specific to a single change or to related changes. Do not mix bugfixes with spelling and other
|
||||
trivial fixes unless the bugfix is trivial too. Do not reorganize code and rename identifiers in the same patch you
|
||||
change behaviour if not necessary. A patch is easier to read and understand if it's to the point and short than
|
||||
if it's not to the point and long :) so the chances for it to be applied are greater.
|
||||
|
||||
2.4 Platform porters:
|
||||
|
||||
1. If you have ported lwIP to a platform (an OS, a uC/processor or a combination of these) and
|
||||
you think it could benefit others[1] you might want discuss this on the mailing list. You
|
||||
can also ask for Git access to submit and maintain your port in the contrib Git module.

|
||||
*
|
||||
* lwIP is a small independent implementation of the TCP/IP protocol suite that has been developed by Adam Dunkels at the Computer and Networks Architectures (CNA) lab at the Swedish Institute of Computer Science (SICS).
|
||||
*
|
||||
* The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP. This making lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.
|
||||
*
|
||||
* \section lwip_features_sec lwIP features:
|
||||
*
|
||||
* \li \c IP (Internet Protocol) including packet forwarding over multiple network interfaces\n
|
||||
* \li \c ICMP (Internet Control Message Protocol) for network maintenance and debugging\n
|
||||
* \li \c IGMP (Internet Group Management Protocol) for multicast traffic management\n
|
||||
* \li \c UDP (User Datagram Protocol) including experimental UDP-lite extensions\n
|
||||
* \li \c TCP (Transmission Control Protocol) with congestion control, RTT estimation and fast recovery/fast retransmit\n
|
||||
* \li \c raw/native API for enhanced performance\n
|
||||
* \li \c Optional Berkeley-like socket API\n
|
||||
* \li \c DNS (Domain names resolver)\n
|
||||
* \li \c SNMP (Simple Network Management Protocol)\n
|
||||
* \li \c DHCP (Dynamic Host Configuration Protocol)\n
|
||||
* \li \c AUTOIP (for IPv4, conform with RFC 3927)\n
|
||||
* \li \c PPP (Point-to-Point Protocol)\n
|
||||
* \li \c ARP (Address Resolution Protocol) for Ethernet\n
|
||||
*
|

* \section install_sec Documentation
|
||||
*
|
||||
* Development of lwIP is hosted on Savannah, a central point for software development, maintenance and distribution. Everyone can help improve lwIP by use of Savannah's interface, Git and the mailing list. A core team of developers will commit changes to the Git source tree.\n
|
||||
* http://savannah.nongnu.org/projects/lwip/\n
|
||||
* \n
|
||||
* The original out-dated homepage of lwIP and Adam Dunkels' papers on lwIP are at the official lwIP home page:\n
|
||||
* http://www.sics.se/~adam/lwip/\n
|
||||
* \n
|
||||
* Self documentation of the source code is regularly extracted from the current Git sources and is available from this web page:\n
|
||||
* http://www.nongnu.org/lwip/\n
|
||||
* \n
|
||||
* There is now a constantly growin wiki about lwIP at\n
|
||||
* http://lwip.wikia.com/\n
|
||||
* \n
|
||||
* Also, there are mailing lists you can subscribe at\n
|
||||
* http://savannah.nongnu.org/mail/?group=lwip\n
|
||||
* plus searchable archives:\n
|
||||
* http://lists.nongnu.org/archive/html/lwip-users/\n
|
||||
* http://lists.nongnu.org/archive/html/lwip-devel/\n
|
||||
* \n
|
||||
* Reading Adam's papers, the files in docs/, browsing the source code documentation and browsing the mailing list archives is a good way to become familiar with the design of lwIP.\n

1 Supported PPP protocols and features
|
||||
======================================
|
||||
|
||||
Supported Low level protocols:
|
||||
* PPP over serial using HDLC-like framing, such as wired dialup modems
|
||||
or mobile telecommunications GPRS/EDGE/UMTS/HSPA+/LTE modems
|
||||
* PPP over Ethernet, such as xDSL modems
|
||||
* PPP over L2TP (Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator),
|
||||
IP tunnel over UDP, such as VPN access
|
||||
|
||||
Supported auth protocols:
|
||||
* PAP, Password Authentication Protocol
|
||||
* CHAP, Challenge-Handshake Authentication Protocol, also known as CHAP-MD5
|
||||
* MSCHAPv1, Microsoft version of CHAP, version 1
|
||||
* MSCHAPv2, Microsoft version of CHAP, version 2
|
||||
* EAP, Extensible Authentication Protocol
|
||||
|
||||
Supported address protocols:
|
||||
* IPCP, IP Control Protocol, IPv4 addresses negotiation
|
||||
* IP6CP, IPv6 Control Protocol, IPv6 link-local addresses negotiation
|
||||
|
||||
Supported encryption protocols:

|
||||
for NO_SYS=1 systems or called inside lwIP core thread for NO_SYS=0 systems.

3 PPPoS input path (raw API, IRQ safe API, TCPIP API)
|
||||
=====================================================
|
||||
|
||||
Received data on serial port should be sent to lwIP using the pppos_input()
|
||||
function or the pppos_input_tcpip() function.
|
||||
|
||||
If NO_SYS is 1 and if PPP_INPROC_IRQ_SAFE is 0 (the default), pppos_input()
|
||||
is not IRQ safe and then *MUST* only be called inside your main loop.
|
||||
|
||||
Whatever the NO_SYS value, if PPP_INPROC_IRQ_SAFE is 1, pppos_input() is IRQ
|
||||
safe and can be safely called from an interrupt context, using that is going
|
||||
to reduce your need of buffer if pppos_input() is called byte after byte in
|
||||
your rx serial interrupt.
|
||||
|
||||
if NO_SYS is 0, the thread safe way outside an interrupt context is to use
|
||||
the pppos_input_tcpip() function to pass input data to the lwIP core thread
|
||||
using the TCPIP API. This is thread safe in all cases but you should avoid
|
||||
passing data byte after byte because it uses heavy locking (mailbox) and it
|
||||
allocates pbuf, better fill them !
|
||||
|
||||
if NO_SYS is 0 and if PPP_INPROC_IRQ_SAFE is 1, you may also use pppos_input()
|
||||
from an RX thread, however pppos_input() is not thread safe by itself. You can
|
||||
do that *BUT* you should NEVER call pppos_connect(), pppos_listen() and
|
||||
ppp_free() if pppos_input() can still be running, doing this is NOT thread safe
|
||||
at all. Using PPP_INPROC_IRQ_SAFE from an RX thread is discouraged unless you
|
||||
really know what you are doing, your move ;-)

4 Thread safe PPP API (PPPAPI)
|
||||
==============================
|
||||
|
||||
There is a thread safe API for all corresponding ppp_* functions, you have to
|
||||
enable LWIP_PPP_API in your lwipopts.h file, then see include/lwip/pppapi.h,
|
||||
this is actually pretty obvious.
|
||||
|
||||
|
||||
|
||||
5 Upgrading from lwIP <= 1.4.x to lwIP >= 1.5.x
|
||||
===============================================
|
||||
|
||||
PPP API was fully reworked between 1.4.x and 1.5.x releases. However porting
|
||||
from previous lwIP version is pretty easy:
|
||||
|
||||
* Previous PPP API used an integer to identify PPP sessions, we are now
|
||||
using ppp_pcb* control block, therefore all functions changed from "int ppp"
|
||||
to "ppp_pcb *ppp"
|
||||
|
||||
* struct netif was moved outside the PPP structure, you have to provide a netif
|
||||
for PPP interface in pppoX_create() functions
|
||||
|
||||
* PPP session are not started automatically after you created them anymore,
|
||||
you have to call ppp_connect(), this way you can configure the session before
|
||||
starting it.
|
||||
|
||||
* Previous PPP API used CamelCase, we are now using snake_case.
|
||||
|
||||
* Previous PPP API mixed PPPoS and PPPoE calls, this isn't the case anymore,
|
||||
PPPoS functions are now prefixed pppos_ and PPPoE functions are now prefixed
|
||||
pppoe_, common functions are now prefixed ppp_.
|
||||
|
||||
* New PPPERR_ error codes added, check you have all of them in your status
|
||||
callback function
|
||||
|
||||
* Only the following include files should now be used in user application:
|
||||
#include "lwip/pppapi.h"
|
||||
#include "netif/ppp/pppos.h"
|
||||
#include "netif/ppp/pppoe.h"
|
||||
#include "netif/ppp/pppol2tp.h"
|
||||
|
||||
Functions from ppp.h can be used, but you don't need to include this header
|
||||
file as it is already included by above header files.
|
||||
|
||||
* PPP_INPROC_OWNTHREAD was broken by design and was removed, you have to create
|
||||
your own serial rx thread
|
||||
|
||||
* PPP_INPROC_MULTITHREADED option was misnamed and confusing and was renamed
|
||||
PPP_INPROC_IRQ_SAFE, please read the "PPPoS input path" documentation above
|
||||
because you might have been fooled by that
|
||||
|
||||
* If you used tcpip_callback_with_block() on ppp_ functions you may wish to use
|
||||
the PPPAPI API instead.
|
||||
|
||||
* ppp_sighup and ppp_close functions were merged using an optional argument
|
||||
"nocarrier" on ppp_close.
|
||||
|
||||
* DNS servers are now only remotely asked if LWIP_DNS is set and we are now
|
||||
unconditionally registering them, which is probably the wanted behavior in
|
||||
almost all cases. If you need it conditional contact us and we will made it
|
||||
conditional.
|
||||
|
||||
* PPPoS now requires a serial output callback
|
||||
|
||||
* PPP_MAXIDLEFLAG is now in ms instead of jiffies

Raw TCP/IP interface for lwIP

Raw TCP/IP interface for lwIP 0.5

|

lwIP provides three Application Program's Interfaces (APIs) for programs
|
||||
to use for communication with the TCP/IP code:
|
||||
* low-level "core" / "callback" or "raw" API.
|
||||
* higher-level "sequential" API.
|
||||
* BSD-style socket API.
|

$Id: rawapi.txt,v 1.1.1.1 2002/10/19 12:59:32 likewise Exp $
|
||||
|
||||
The raw API (sometimes called native API) is an event-driven API designed
|
||||
to be used without an operating system that implements zero-copy send and
|
||||
receive. This API is also used by the core stack for interaction between
|
||||
the various protocols. It is the only API available when running lwIP
|
||||
without an operating system.
|
||||
lwIP provides two Application Program's Interfaces (APIs) for programs
|
||||
to use for communication with the TCP/IP code: the sequential API
|
||||
(often just called "the API") and the raw TCP/IP interface. This
|
||||
document is intended as a description of the latter. For lwIP versions
|
||||
lower than 0.5, this API was not documented.
|
||||
|
||||
The sequential API provides a way for ordinary, sequential, programs
|
||||
to use the lwIP stack. It is quite similar to the BSD socket API. The
|
||||
model of execution is based on the blocking open-read-write-close
|
||||
model of execution is based on the open-read-write-close
|
||||
paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP
|
||||
code and the application program must reside in different execution
|
||||
contexts (threads).
|
||||
|
||||
The socket API is a compatibility API for existing applications,
|
||||
currently it is built on top of the sequential API. It is meant to
|
||||
provide all functions needed to run socket API applications running
|
||||
on other platforms (e.g. unix / windows etc.). However, due to limitations
|
||||
in the specification of this API, there might be incompatibilities
|
||||
that require small modifications of existing programs.
|
||||
|
||||
** Multithreading
|
||||
|
||||
lwIP started targeting single-threaded environments. When adding multi-
|
||||
threading support, instead of making the core thread-safe, another
|
||||
approach was chosen: there is one main thread running the lwIP core
|
||||
(also known as the "tcpip_thread"). When running in a multithreaded
|
||||
environment, raw API functions MUST only be called from the core thread
|
||||
since raw API functions are not protected from concurrent access (aside
|
||||
from pbuf- and memory management functions). Application threads using
|
||||
the sequential- or socket API communicate with this main thread through
|
||||
message passing.
|
||||
|
||||
As such, the list of functions that may be called from
|
||||
other threads or an ISR is very limited! Only functions
|
||||
from these API header files are thread-safe:
|
||||
- api.h
|
||||
- netbuf.h
|
||||
- netdb.h
|
||||
- netifapi.h
|
||||
- pppapi.h
|
||||
- sockets.h
|
||||
- sys.h
|
||||
|
||||
Additionaly, memory (de-)allocation functions may be
|
||||
called from multiple threads (not ISR!) with NO_SYS=0
|
||||
since they are protected by SYS_LIGHTWEIGHT_PROT and/or
|
||||
semaphores.
|
||||
|
||||
Netconn or Socket API functions are thread safe against the
|
||||
core thread but they are not reentrant at the control block
|
||||
granularity level. That is, a UDP or TCP control block must
|
||||
not be shared among multiple threads without proper locking.
|
||||
|
||||
If SYS_LIGHTWEIGHT_PROT is set to 1 and
|
||||
LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT is set to 1,
|
||||
pbuf_free() may also be called from another thread or
|
||||
an ISR (since only then, mem_free - for PBUF_RAM - may
|
||||
be called from an ISR: otherwise, the HEAP is only
|
||||
protected by semaphores).

--- System initalization
|
||||
|
||||
A truly complete and generic sequence for initializing the lwIP stack
|
||||
cannot be given because it depends on additional initializations for
|
||||
your runtime environment (e.g. timers).
|
||||
|
||||
We can give you some idea on how to proceed when using the raw API.
|
||||
We assume a configuration using a single Ethernet netif and the
|
||||
UDP and TCP transport layers, IPv4 and the DHCP client.
|
||||
|
||||
Call these functions in the order of appearance:
|
||||
|
||||
- lwip_init()
|
||||
|
||||
Initialize the lwIP stack and all of its subsystems.
|
||||
|
||||
- netif_add(struct netif *netif, const ip4_addr_t *ipaddr,
|
||||
const ip4_addr_t *netmask, const ip4_addr_t *gw,
|
||||
void *state, netif_init_fn init, netif_input_fn input)
|
||||
|
||||
Adds your network interface to the netif_list. Allocate a struct
|
||||
netif and pass a pointer to this structure as the first argument.
|
||||
Give pointers to cleared ip_addr structures when using DHCP,
|
||||
or fill them with sane numbers otherwise. The state pointer may be NULL.
|
||||
|
||||
The init function pointer must point to a initialization function for
|
||||
your Ethernet netif interface. The following code illustrates its use.
|
||||
|
||||
err_t netif_if_init(struct netif *netif)
|
||||
{
|
||||
u8_t i;
|
||||
|
||||
for (i = 0; i < ETHARP_HWADDR_LEN; i++) {
|
||||
netif->hwaddr[i] = some_eth_addr[i];
|
||||
}
|
||||
init_my_eth_device();
|
||||
return ERR_OK;
|
||||
}
|
||||
|
||||
For Ethernet drivers, the input function pointer must point to the lwIP
|
||||
function ethernet_input() declared in "netif/etharp.h". Other drivers
|
||||
must use ip_input() declared in "lwip/ip.h".
|
||||
|
||||
- netif_set_default(struct netif *netif)
|
||||
|
||||
Registers the default network interface.
|
||||
|
||||
- netif_set_link_up(struct netif *netif)
|
||||
|
||||
This is the hardware link state; e.g. whether cable is plugged for wired
|
||||
Ethernet interface. This function must be called even if you don't know
|
||||
the current state. Having link up and link down events is optional but
|
||||
DHCP and IPv6 discover benefit well from those events.
|
||||
|
||||
- netif_set_up(struct netif *netif)
|
||||
|
||||
This is the administrative (= software) state of the netif, when the
|
||||
netif is fully configured this function must be called.
|
||||
|
||||
- dhcp_start(struct netif *netif)
|
||||
|
||||
Creates a new DHCP client for this interface on the first call.
|
||||
|
||||
You can peek in the netif->dhcp struct for the actual DHCP status.
|
||||
|
||||
- sys_check_timeouts()
|
||||
|
||||
When the system is running, you have to periodically call
|
||||
sys_check_timeouts() which will handle all timers for all protocols in
|
||||
the stack; add this to your main loop or equivalent.
|
||||
|
||||
|
||||
--- Optimalization hints
|
||||
|
||||
The first thing you want to optimize is the lwip_standard_checksum()
|
||||
routine from src/core/inet.c. You can override this standard
|
||||
function with the #define LWIP_CHKSUM <your_checksum_routine>.
|
||||
|
||||
There are C examples given in inet.c or you might want to
|
||||
craft an assembly function for this. RFC1071 is a good
|
||||
introduction to this subject.
|
||||
|
||||
Other significant improvements can be made by supplying
|
||||
assembly or inline replacements for htons() and htonl()
|
||||
if you're using a little-endian architecture.
|
||||
#define LWIP_PLATFORM_BYTESWAP 1
|
||||
#define LWIP_PLATFORM_HTONS(x) <your_htons>
|
||||
#define LWIP_PLATFORM_HTONL(x) <your_htonl>
|
||||
|
||||
Check your network interface driver if it reads at
|
||||
a higher speed than the maximum wire-speed. If the
|
||||
hardware isn't serviced frequently and fast enough
|
||||
buffer overflows are likely to occur.
|
||||
|
||||
E.g. when using the cs8900 driver, call cs8900if_service(ethif)
|
||||
as frequently as possible. When using an RTOS let the cs8900 interrupt
|
||||
wake a high priority task that services your driver using a binary
|
||||
semaphore or event flag. Some drivers might allow additional tuning
|
||||
to match your application and network.
|
||||
|
||||
For a production release it is recommended to set LWIP_STATS to 0.
|
||||
Note that speed performance isn't influenced much by simply setting
|
||||
high values to the memory options.
|
||||
|
||||
For more optimization hints take a look at the lwIP wiki.
|
||||
|
||||
--- Zero-copy MACs
|
||||
|
||||
To achieve zero-copy on transmit, the data passed to the raw API must
|
||||
remain unchanged until sent. Because the send- (or write-)functions return
|
||||
when the packets have been enqueued for sending, data must be kept stable
|
||||
after that, too.
|
||||
|
||||
This implies that PBUF_RAM/PBUF_POOL pbufs passed to raw-API send functions
|
||||
must *not* be reused by the application unless their ref-count is 1.
|
||||
|
||||
For no-copy pbufs (PBUF_ROM/PBUF_REF), data must be kept unchanged, too,
|
||||
but the stack/driver will/must copy PBUF_REF'ed data when enqueueing, while
|
||||
PBUF_ROM-pbufs are just enqueued (as ROM-data is expected to never change).
|
||||
|
||||
Also, data passed to tcp_write without the copy-flag must not be changed!
|
||||
|
||||
Therefore, be careful which type of PBUF you use and if you copy TCP data
|
||||
or not!
|
||||
datagram is received.

|
||||
|
||||
|
||||
1 Obtaining lwIP from the Git repository
|
||||
----------------------------------------
|
||||
|
||||
To perform an anonymous Git clone of the master branch (this is where
|
||||
bug fixes and incremental enhancements occur), do this:
|
||||
git clone git://git.savannah.nongnu.org/lwip.git
|
||||
|
||||
Or, obtain a stable branch (updated with bug fixes only) as follows:
|
||||
git clone --branch DEVEL-1_4_1 git://git.savannah.nongnu.org/lwip.git
|
||||
|
||||
Or, obtain a specific (fixed) release as follows:
|
||||
git clone --branch STABLE-1_4_1 git://git.savannah.nongnu.org/lwip.git
|
||||
|
||||
|
||||
2 Committers/developers Git access using SSH
|
||||
--------------------------------------------
|
||||
|
||||
The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption.
|
||||
As such, Git commits to the server occur through a SSH tunnel for project members.
|
||||
To create a SSH2 key pair in UNIX-like environments, do this:
|
||||
ssh-keygen -t dsa
|
||||
|
||||
Under Windows, a recommended SSH client is "PuTTY", freely available with good
|
||||
documentation and a graphic user interface. Use its key generator.
|
||||
|
||||
Now paste the id_dsa.pub contents into your Savannah account public key list. Wait
|
||||
a while so that Savannah can update its configuration (This can take minutes).
|
||||
|
||||
Try to login using SSH:
|
||||
ssh -v your_login@git.sv.gnu.org
|
||||
|
||||
If it tells you:
|
||||
Linux vcs.savannah.gnu.org 2.6.32-5-xen-686 #1 SMP Wed Jun 17 17:10:03 UTC 2015 i686
|
||||
|
||||
Interactive shell login is not possible for security reasons.
|
||||
VCS commands are allowed.
|
||||
Last login: Tue May 15 23:10:12 2012 from 82.245.102.129
|
||||
You tried to execute:
|
||||
Sorry, you are not allowed to execute that command.
|
||||
Shared connection to git.sv.gnu.org closed.
|
||||
|
||||
then you could login; Savannah refuses to give you a shell - which is OK, as we
|
||||
are allowed to use SSH for Git only. Now, you should be able to do this:
|
||||
git clone your_login@git.sv.gnu.org:/srv/git/lwip.git
|
||||
|
||||
After which you can edit your local files with bug fixes or new features and
|
||||
commit them. Make sure you know what you are doing when using Git to make
|
||||
changes on the repository. If in doubt, ask on the lwip-members mailing list.
|
||||
|
||||
(If SSH asks about authenticity of the host, you can check the key
|
||||
fingerprint against https://savannah.nongnu.org/git/?group=lwip
|
||||
|
||||
|
||||
3 - Merging a development branch to master branch
|
||||
-------------------------------------------------
|
||||
|
||||
Merging is a straightforward process in Git. How to merge all changes in a
|
||||
development branch since our last merge from main:
|
||||
|
||||
Checkout the master branch:
|
||||
git checkout master
|
||||
|
||||
Merge the development branch to master:
|
||||
git merge your-development-branch
|
||||
|
||||
Resolve any conflict.
|
||||
|
||||
Commit the merge result.
|
||||
git commit -a
|
||||
|
||||
Push your commits:
|
||||
git push
|
||||
|
||||
|
||||
4 How to release lwIP
|
||||
---------------------
|
||||
|
||||
First, tag the release using Git: (I use release number 1.4.1 throughout
|
||||
this example).
|
||||
git tag -a STABLE-1_4_1
|
||||
|
||||
Share the tag reference by pushing it to remote:
|
||||
git push origin STABLE-1_4_1
|
||||
|
||||
Prepare the release:
|
||||
cp -r lwip lwip-1.4.1
|
||||
rm -rf lwip-1.4.1/.git lwip-1.4.1/.gitattributes
|
||||
|
||||
Archive the current directory using tar, gzip'd, bzip2'd and zip'd.
|
||||
tar czvf lwip-1.4.1.tar.gz lwip-1.4.1
|
||||
tar cjvf lwip-1.4.1.tar.bz2 lwip-1.4.1
|
||||
zip -r lwip-1.4.1.zip lwip-1.4.1
|
||||
|
||||
Now, sign the archives with a detached GPG binary signature as follows:
|
||||
gpg -b lwip-1.4.1.tar.gz
|
||||
gpg -b lwip-1.4.1.tar.bz2
|
||||
gpg -b lwip-1.4.1.zip
|
||||
|
||||
Upload these files using anonymous FTP:
|
||||
ncftp ftp://savannah.gnu.org/incoming/savannah/lwip
|
||||
ncftp> mput *1.4.1.*
|
||||
|
||||
Additionally, you may post a news item on Savannah, like this:
|
||||
|
||||
A new 1.4.1 release is now available here:
|
||||
http://savannah.nongnu.org/files/?group=lwip&highlight=1.4.1
|
||||
|
||||
You will have to submit this via the user News interface, then approve
|

SNMPv1 agent for lwIP
|
||||
|
||||
Author: Christiaan Simons
|
||||
|
||||
This is a brief introduction how to use and configure the SNMP agent.
|
||||
Note the agent uses the raw-API UDP interface so you may also want to
|
||||
read rawapi.txt to gain a better understanding of the SNMP message handling.
|
||||
|
||||
0 Agent Capabilities
|
||||
====================
|
||||
|
||||
SNMPv1 per RFC1157
|
||||
This is an old(er) standard but is still widely supported.
|
||||
For SNMPv2c and v3 have a greater complexity and need many
|
||||
more lines of code. IMHO this breaks the idea of "lightweight IP".
|
||||
|
||||
Note the S in SNMP stands for "Simple". Note that "Simple" is
|
||||
relative. SNMP is simple compared to the complex ISO network
|
||||
management protocols CMIP (Common Management Information Protocol)
|
||||
and CMOT (CMip Over Tcp).
|
||||
|
||||
MIB II per RFC1213
|
||||
The standard lwIP stack management information base.
|
||||
This is a required MIB, so this is always enabled.
|
||||
When builing lwIP without TCP, the mib-2.tcp group is omitted.
|
||||
The groups EGP, CMOT and transmission are disabled by default.
|
||||
|
||||
Most mib-2 objects are not writable except:
|
||||
sysName, sysLocation, sysContact, snmpEnableAuthenTraps.
|
||||
Writing to or changing the ARP and IP address and route
|
||||
tables is not possible.
|
||||
|
||||
Note lwIP has a very limited notion of IP routing. It currently
|
||||
doen't have a route table and doesn't have a notion of the U,G,H flags.
|
||||
Instead lwIP uses the interface list with only one default interface
|
||||
acting as a single gateway interface (G) for the default route.
|
||||
|
||||
The agent returns a "virtual table" with the default route 0.0.0.0
|
||||
for the default interface and network routes (no H) for each
|
||||
network interface in the netif_list.
|
||||
All routes are considered to be up (U).
|
||||
|
||||
Loading additional MIBs
|
||||
MIBs can only be added in compile-time, not in run-time.
|
||||
There is no MIB compiler thus additional MIBs must be hand coded.
|
||||
|
||||
Large SNMP message support
|
||||
The packet decoding and encoding routines are designed
|
||||
to use pbuf-chains. Larger payloads than the minimum
|
||||
SNMP requirement of 484 octets are supported if the
|
||||
PBUF_POOL_SIZE and IP_REASS_BUFSIZE are set to match your
|
||||
local requirement.
|
||||
|
||||
1 Building the Agent
|
||||
====================
|
||||
|
||||
First of all you'll need to add the following define
|
||||
to your local lwipopts.h:
|
||||
|
||||
#define LWIP_SNMP 1
|
||||
|
||||
and add the source files in lwip/src/core/snmp
|
||||
and some snmp headers in lwip/src/include/lwip to your makefile.
|
||||
|
||||
Note you'll might need to adapt you network driver to update
|
||||
the mib2 variables for your interface.
|
||||
|
||||
2 Running the Agent
|
||||
===================
|
||||
|
||||
The following function calls must be made in your program to
|
||||
actually get the SNMP agent running.
|
||||
|
||||
Before starting the agent you should supply pointers
|
||||
to non-volatile memory for sysContact, sysLocation,
|
||||
and snmpEnableAuthenTraps. You can do this by calling
|
||||
|
||||
snmp_set_syscontact()
|
||||
snmp_set_syslocation()
|
||||
snmp_set_snmpenableauthentraps()
|
||||
|
||||
Additionally you may want to set
|
||||
|
||||
snmp_set_sysdescr()
|
||||
snmp_set_sysobjid() (if you have a private MIB)
|
||||
snmp_set_sysname()
|
||||
|
||||
Also before starting the agent you need to setup
|
||||
one or more trap destinations using these calls:
|
||||
|
||||
snmp_trap_dst_enable();
|
||||
snmp_trap_dst_ip_set();
|
||||
|
||||
|
||||
3 Private MIBs
|
||||
==============
|
||||
|
||||
If want to extend the agent with your own private MIB you'll need to
|
||||
add the following define to your local lwipopts.h:
|
||||
|
||||
#define SNMP_PRIVATE_MIB 1
|
||||
|
||||
You must provide the private_mib.h and associated files yourself.
|
||||
Note we don't have a "MIB compiler" that generates C source from a MIB,
|
||||
so you're required to do some serious coding if you enable this!
|
||||
|
||||
Note the lwIP enterprise ID (26381) is assigned to the lwIP project,
|
||||
ALL OBJECT IDENTIFIERS LIVING UNDER THIS ID ARE ASSIGNED BY THE lwIP
|
||||
MAINTAINERS!
|
||||
|
||||
If you need to create your own private MIB you'll need
|
||||
to apply for your own enterprise ID with IANA: http://www.iana.org/numbers.html
|
||||
|
||||
You can set it by passing a struct snmp_obj_id to the agent
|
||||
using snmp_set_sysobjid(&my_object_id), just before snmp_init().
|
||||
|
||||
Note the object identifiers for thes MIB-2 and your private MIB
|
||||
tree must be kept in sorted ascending (lexicographical) order.
|
||||
This to ensure correct getnext operation.
|
||||
|
||||
An example for a private MIB is part of the "minimal Unix" project:
|
||||
contrib/ports/unix/proj/minimal/lwip_prvmib.c
|
||||
|
||||
The next chapter gives a more detailed description of the
|
||||
MIB-2 tree and the optional private MIB.
|
||||
|
||||
4 The Gory Details
|
||||
==================
|
||||
|
||||
4.0 Object identifiers and the MIB tree.
|
||||
|
||||
We have three distinct parts for all object identifiers:
|
||||
|
||||
The prefix
|
||||
.iso.org.dod.internet

turn use dynamically allocated index trees from RAM.

These trees are updated by e.g. the etharp code
|
||||
when new entries are made or removed form the ARP cache.

In addition to the source file providing the functionality of sys_arch,

the OS emulation layer must provide several header files defining

macros used throughout lwip. The files required and the macros they

must define are listed below the sys_arch description.

type "sys_mbox_t". lwIP does not place any restrictions on how
|

sys_sem_t or sys_mbox_t are represented internally.
|
||||
|
||||
Since lwIP 1.4.0, semaphore and mailbox functions are prototyped in a way that
|
||||
allows both using pointers or actual OS structures to be used. This way, memory
|
||||
required for such types can be either allocated in place (globally or on the
|
||||
stack) or on the heap (allocated internally in the "*_new()" functions).
|
||||
|
||||
The following functions must be implemented by the sys_arch:
|
||||
|
||||
- void sys_init(void)
|
||||
|
||||
Is called to initialize the sys_arch layer.
|
||||
|
||||
- err_t sys_sem_new(sys_sem_t *sem, u8_t count)
|
||||
- sys_sem_t sys_sem_new(u8_t count)
|
||||
|
||||
Creates a new semaphore. The semaphore is allocated to the memory that 'sem'
|
||||
points to (which can be both a pointer or the actual OS structure).
|
||||
The "count" argument specifies the initial state of the semaphore (which is
|
||||
either 0 or 1).
|
||||
If the semaphore has been created, ERR_OK should be returned. Returning any
|
||||
other error will provide a hint what went wrong, but except for assertions,
|
||||
no real error handling is implemented.

- void sys_sem_signal(sys_sem_t *sem)

- void sys_sem_signal(sys_sem_t sem)
|

Signals a semaphore.
|

- u32_t sys_arch_sem_wait(sys_sem_t *sem, u32_t timeout)
|

- u16_t sys_arch_sem_wait(sys_sem_t sem, u16_t timeout)

Blocks the thread while waiting for the semaphore to be
|
||||
signaled. If the "timeout" argument is non-zero, the thread should

only be blocked for the specified time (measured in

milliseconds). If the "timeout" argument is zero, the thread should be

milliseconds).
|
||||
|
||||
If the timeout argument is non-zero, the return value is the number of
|
||||
milliseconds spent waiting for the semaphore to be signaled. If the
|
||||
semaphore wasn't signaled within the specified time, the return value is
|
||||
SYS_ARCH_TIMEOUT. If the thread didn't have to wait for the semaphore
|
||||
(i.e., it was already signaled), the function may return zero.
|
||||
If the timeout argument is non-zero, the return value is the amount
|
||||
of time spent waiting for the semaphore to be signaled. If the
|
||||
semaphore wasn't signaled within the specified time, the return
|
||||
value is zero. If the thread didn't have to wait for the semaphore
|
||||
(i.e., it was already signaled), care must be taken to ensure that
|
||||
the function does not return a zero value since this is used to
|
||||
indicate that a timeout occured. A suitable way to implement this is
|
||||
to check if the time spent waiting is zero and if so, the value 1 is
|
||||
returned.
|
||||
|
||||
Notice that lwIP implements a function with a similar name,
|
||||
sys_sem_wait(), that uses the sys_arch_sem_wait() function.
|
||||
|
||||
- int sys_sem_valid(sys_sem_t *sem)
|
||||
- sys_mbox_t sys_mbox_new(void)
|
||||
|
||||
Returns 1 if the semaphore is valid, 0 if it is not valid.
|
||||
When using pointers, a simple way is to check the pointer for != NULL.
|
||||
When directly using OS structures, implementing this may be more complex.
|
||||
This may also be a define, in which case the function is not prototyped.
|
||||
Creates an empty mailbox.
|
||||
|
||||
- void sys_sem_set_invalid(sys_sem_t *sem)
|
||||
|
||||
Invalidate a semaphore so that sys_sem_valid() returns 0.
|
||||
ATTENTION: This does NOT mean that the semaphore shall be deallocated:
|
||||
sys_sem_free() is always called before calling this function!
|
||||
This may also be a define, in which case the function is not prototyped.
|
||||
|
||||
- err_t sys_mbox_new(sys_mbox_t *mbox, int size)
|
||||
|
||||
Creates an empty mailbox for maximum "size" elements. Elements stored
|
||||
in mailboxes are pointers. You have to define macros "_MBOX_SIZE"
|
||||
in your lwipopts.h, or ignore this parameter in your implementation
|
||||
and use a default size.
|
||||
If the mailbox has been created, ERR_OK should be returned. Returning any
|
||||
other error will provide a hint what went wrong, but except for assertions,
|
||||
no real error handling is implemented.
|
||||
|
||||
- void sys_mbox_free(sys_mbox_t *mbox)
|
||||
- void sys_mbox_free(sys_mbox_t mbox)
|
||||
|
||||
Deallocates a mailbox. If there are messages still present in the
|
||||
mailbox when the mailbox is deallocated, it is an indication of a
|
||||
programming error in lwIP and the developer should be notified.
|
||||
|
||||
- void sys_mbox_post(sys_mbox_t *mbox, void *msg)
|
||||
- void sys_mbox_post(sys_mbox_t mbox, void *msg)
|
||||
|
||||
Posts the "msg" to the mailbox. This function have to block until
|
||||
the "msg" is really posted.
|
||||
Posts the "msg" to the mailbox.
|
||||
|
||||
- err_t sys_mbox_trypost(sys_mbox_t *mbox, void *msg)
|
||||
|
||||
Try to post the "msg" to the mailbox. Returns ERR_MEM if this one
|
||||
is full, else, ERR_OK if the "msg" is posted.
|
||||
|
||||
- u32_t sys_arch_mbox_fetch(sys_mbox_t *mbox, void **msg, u32_t timeout)
|
||||
- u16_t sys_arch_mbox_fetch(sys_mbox_t mbox, void **msg, u16_t timeout)
|
||||
|
||||
Blocks the thread until a message arrives in the mailbox, but does
|
||||
not block the thread longer than "timeout" milliseconds (similar to
|
||||
the sys_arch_sem_wait() function). If "timeout" is 0, the thread should
|
||||
be blocked until a message arrives. The "msg" argument is a result
|
||||
the sys_arch_sem_wait() function). The "msg" argument is a result
|
||||
parameter that is set by the function (i.e., by doing "*msg =
|
||||
ptr"). The "msg" parameter maybe NULL to indicate that the message
|
||||
should be dropped.
|
||||
|
||||
The return values are the same as for the sys_arch_sem_wait() function:
|
||||
Number of milliseconds spent waiting or SYS_ARCH_TIMEOUT if there was a
|
||||
timeout.
|
||||
The return values are the same as for the sys_arch_sem_wait()
|
||||
function and the function must not return zero even if a message was
|
||||
present in the mailbox and the time spent waiting was zero
|
||||
milliseconds.
|
||||
|
||||
Note that a function with a similar name, sys_mbox_fetch(), is
|
||||
implemented by lwIP.
|
||||
|
||||
- struct sys_timeouts *sys_arch_timeouts(void)
|
||||
|
||||
- u32_t sys_arch_mbox_tryfetch(sys_mbox_t *mbox, void **msg)
|
||||
|
||||
This is similar to sys_arch_mbox_fetch, however if a message is not
|
||||
present in the mailbox, it immediately returns with the code
|
||||
SYS_MBOX_EMPTY. On success 0 is returned.
|
||||
|
||||
To allow for efficient implementations, this can be defined as a
|
||||
function-like macro in sys_arch.h instead of a normal function. For
|
||||
example, a naive implementation could be:
|
||||
#define sys_arch_mbox_tryfetch(mbox,msg) \
|
||||
sys_arch_mbox_fetch(mbox,msg,1)
|
||||
although this would introduce unnecessary delays.
|
||||
|
||||
- int sys_mbox_valid(sys_mbox_t *mbox)
|
||||
|
||||
Returns 1 if the mailbox is valid, 0 if it is not valid.
|
||||
When using pointers, a simple way is to check the pointer for != NULL.
|
||||
When directly using OS structures, implementing this may be more complex.
|
||||
This may also be a define, in which case the function is not prototyped.
|
||||
|
||||
- void sys_mbox_set_invalid(sys_mbox_t *mbox)
|
||||
|
||||
Invalidate a mailbox so that sys_mbox_valid() returns 0.
|
||||
ATTENTION: This does NOT mean that the mailbox shall be deallocated:
|
||||
sys_mbox_free() is always called before calling this function!
|
||||
This may also be a define, in which case the function is not prototyped.
|
||||
Returns a pointer to the per-thread sys_timeouts structure. In lwIP,
|
||||
each thread has a list of timeouts which is repressented as a linked
|
||||
list of sys_timeout structures. The sys_timeouts structure holds a
|
||||
pointer to a linked list of timeouts. This function is called by
|
||||
the lwIP timeout scheduler and must not return a NULL value.
|
||||
|
||||
In a single threadd sys_arch implementation, this function will
|
||||
simply return a pointer to a global sys_timeouts variable stored in
|
||||
the sys_arch module.
|
||||
|
||||
If threads are supported by the underlying operating system and if
|
||||
such functionality is needed in lwIP, the following function will have
|
||||
to be implemented as well:
|
||||
|
||||
- sys_thread_t sys_thread_new(char *name, void (* thread)(void *arg), void *arg, int stacksize, int prio)
|
||||
- void sys_thread_new(void (* thread)(void *arg), void *arg)
|
||||
|
||||
Starts a new thread named "name" with priority "prio" that will begin its
|
||||
execution in the function "thread()". The "arg" argument will be passed as an
|
||||
argument to the thread() function. The stack size to used for this thread is
|
||||
the "stacksize" parameter. The id of the new thread is returned. Both the id
|
||||
and the priority are system dependent.
|
||||
Starts a new thread that will begin its execution in the function
|
||||
"thread()". The "arg" argument will be passed as an argument to the
|
||||
thread() function.
|
||||
|
||||
- sys_prot_t sys_arch_protect(void)
|
||||
|
||||
This optional function does a "fast" critical region protection and returns
|
||||
the previous protection level. This function is only called during very short
|
||||
critical regions. An embedded system which supports ISR-based drivers might
|
||||
want to implement this function by disabling interrupts. Task-based systems
|
||||
might want to implement this by using a mutex or disabling tasking. This
|
||||
function should support recursive calls from the same task or interrupt. In
|
||||
other words, sys_arch_protect() could be called while already protected. In
|
||||
that case the return value indicates that it is already protected.
|
||||
|
||||
sys_arch_protect() is only required if your port is supporting an operating
|
||||
system.
|
||||
|
||||
- void sys_arch_unprotect(sys_prot_t pval)
|
||||
|
||||
This optional function does a "fast" set of critical region protection to the
|
||||
value specified by pval. See the documentation for sys_arch_protect() for
|
||||
more information. This function is only required if your port is supporting
|
||||
an operating system.
|
||||
|
||||
For some configurations, you also need:
|
||||
|
||||
- u32_t sys_now(void)
|
||||
|
||||
This optional function returns the current time in milliseconds (don't care
|
||||
for wraparound, this is only used for time diffs).
|
||||
Not implementing this function means you cannot use some modules (e.g. TCP
|
||||
timestamps, internal timeouts for NO_SYS==1).
|
||||
|
||||
|
||||
Note:
|
||||
|
||||
Be carefull with using mem_malloc() in sys_arch. When malloc() refers to
|
||||
mem_malloc() you can run into a circular function call problem. In mem.c
|
||||
mem_init() tries to allcate a semaphore using mem_malloc, which of course
|
||||
can't be performed when sys_arch uses mem_malloc.

This is an example of a very minimal lwIP project. It runs in a single
|
||||
thread and runs a single example application - an echo server. The
|
||||
echo application is implemented using the raw API.

This directory contains an example of how a project using lwIP might
|
||||
look. It is also the development platform of lwIP, since it can be run
|
||||
as a user process under FreeBSD or Linux. There are also a number of
|
||||
example applications (including a simple web server) in the apps/
|
||||
directory.
|
||||
|
||||
Some short instructions on how to build and run lwIP on a FreeBSD or
|
||||
Linux host. For FreeBSD, the tap interface must be enabled in the
|
||||
kernel configuration and the kernel must be recompiled. The tap
|
||||
interface is enabled by adding the line "pseudo-device tap" in the
|
||||
kernel configuration. See Chapter 9 in the FreeBSD handbook for
|
||||
instructions on how to build a custom FreeBSD kernel.
|
||||
|
||||
* Compile the code. This must be done by using GNU Make. Under
|
||||
FreeBSD, GNU Make can be found in the ports collection under
|
||||
/usr/ports/devel/gmake (type "make install distclean" to
|
||||
install). Under Linux, GNU Make is the default "make".
|
||||
|
||||
> gmake (FreeBSD)
|
||||
|
||||
> make (Linux)
|
||||
|
||||
* The compilation process produces the executable file "simhost". To
|
||||
run this, you have to be root.
|
||||
|
||||
> su (Type password for the root account)
|
||||
# ./simhost
|
||||
|
||||
* The lwIP TCP/IP stack is now running with IP address
|
||||
192.168.0.2. Some things that you can try:
|
||||
|
||||
To see the packets that are going to and from the lwIP stack, run
|
||||
tcpdump:
|
||||
|
||||
# tcpdump -l -n -i tap0
|
||||
|
||||
You can ping lwIP:
|
||||
|
||||
> ping 192.168.0.2
|
||||
|
||||
For a telnet shell, run:
|
||||
|
||||
> telnet 192.168.0.2
|
||||
|
||||
Finally, "simhost" also includes a simple web server; the URL is
|
||||
of course http://192.168.0.2/.

<h3>Ports</h3>
|
||||
<p align="justify">
|
||||
Florian Shulze has ported lwIP to DJGPP/MS-DOS and to Visual C++
|
||||
6.0/Win32. They can be downloaded <a
|
||||
href="http://homepages.fh-giessen.de/~hg10836/dev/djgpp/lwipdjgpptest-0.1.zip">here</a>
|
||||
(DJGPP/MS-DOS) and <a
|
||||
href="http://homepages.fh-giessen.de/~hg10836/crowproductions/dev/lwip-win32-msvc-0.1.zip">here</a>
|
||||
(Visual C++ 6.0/Win32).

<h3>Add-ons/drivers/applications</h3>
|
||||
|
||||
<h4>DHCP client</h4>
|
||||
<p align="justify">
|
||||
Leon Woestenberg from Axon Digital Design B.V. has written a CS8900a
|
||||
network interface driver and is currently developing a DHCP client for
|
||||
lwIP. They can both be found <a
|
||||
href="http://www.esrac.ele.tue.nl/~leon/lwip/">here</a>. The plan is
|
||||
to eventually integrate Leon's DHCP client in the main lwIP
|
||||
distribution.
|
||||
</p>
|
||||
|
||||
<h4>IGMPv2 implementation</h4>
|
||||
<p align="justify">
|
||||
Steve Reynolds of Citel Technologies Ltd. has donated his IGMPv2
|
||||
implementation for lwIP to the community. It is avaliable for download
|
||||
<a href="download/igmpfiles.zip">here</a> (note that the copyright and
|
||||
license differs slightly from lwIP - read the license in the igmp.c
|
||||
file). The plan is to integrate his code into the main lwIP
|
||||
distribution.
|
||||
</p>
|
||||
|
||||
<h4>Alternative BSD socket layer</h4>
|
||||
<p align="justify">
|
||||
Paul Sheer has incorporated lwIP into his PaulOS system and has
|
||||
written an alternative BSD socket layer. It is avaliable for download
|
||||
<a href="download/bsdsocket.c">here</a>. It is copyright Paul Sheer
|
||||
and licensed under the <a

<h2>Using lwIP with or without an operating system</h2>
|
||||
|
||||
<p align="justify">
|
||||
There has been a few questions about how lwIP can be used in a
|
||||
standalone environment (i.e., an environment without a multi-threaded
|
||||
operating system) lately. The purpose of this document is to describe
|
||||
how lwIP is designed to be used with and without a multi-threaded
|
||||
operating system.
|
||||
</p>
|
||||
|
||||
<center><img src="os.png"></center>
|
||||
|
||||
<h3>The lwIP single-threaded core</h3>
|
||||
<p align="justify">
|
||||
The core of lwIP consists of the actual implementations of the IP,
|
||||
ICMP, UDP, and TCP protocols, as well as the support functions such as
|
||||
buffer and memory management. The core components are the only ones
|
||||
that are needed when lwIP is to be run in a single-threaded (non-OS)
|
||||
environment.
|
||||
</p>
|
||||
<p align="justify">
|
||||
The core components can be viewed as a software library which has the
|
||||
following interface:
|
||||
</p>
|
||||
<ul>
|
||||
<li><tt>ip_input(pbuf, netif)</tt>: Takes an IP packet and the incoming network
|
||||
interface as arguments and does the TCP/IP processing for the packet.
|
||||
<li><tt>tcp_tmr()</tt>: Should be called every 100 ms. Does all TCP
|
||||
timer processing such as doing retransmissions.
|
||||
</ul>
|
||||
<p align="justify">
|
||||
Because none of the core functions ever needs to block when run in a
|
||||
single-threaded environment, the <tt>sys_arch</tt> (the operating
|
||||
system abstraction layer) does not need to implement locking
|
||||
semaphores or mailboxes. In future versions of lwIP, the dependancy of
|
||||
the <tt>sys_arch</tt> will be removed in the single-threaded case.
|
||||
</p>
|
||||
<p align="justify">
|
||||
A simple main loop for a single-threaded system might look
|
||||
like this:
|
||||
</p>
|
||||
<pre>
|
||||
while(1) {
|
||||
if(poll_driver(netif) == PACKET_READY) {
|
||||
pbuf = get_packet(netif);
|
||||
ip_input(pbuf, netif);
|
||||
}
|
||||
|
||||
if(clock() - last_time == 100 * CLOCK_MS) {
|
||||
tcp_tmr();
|
||||
last_time = clock();
|
||||
}
|
||||
}
|
||||
</pre>
|
||||
|
||||
<h3>lwIP in a multi-threaded system</h3>
|
||||
<p align="justify">
|
||||
lwIP is designed to be able to be run in a multi-threaded system with
|
||||
applications running in concurrent threads. The model used in this
|
||||
case is that all TCP/IP processing is done in a single thread. The
|
||||
application thread communicate with the TCP/IP thread using the
|
||||
sequential API.
|
||||
</p>
|
||||
|
||||
<center><img src="threads.png"></center>
|
||||
|
||||
<p align="justify">
|
||||
The inter-thread communication is implemented in the two files
|
||||
<tt>api_lib.c</tt> and <tt>api_msg.c</tt>. The former contains the
|
||||
functions used by the application programs and the latter implements
|
||||
the TCP/IP stack interface. A third file, <tt>tcpip.c</tt>, handles
|
||||
incoming packets and timer events as described in the previous
|
||||
section.
|
||||
</p>
|
||||
|
||||
<p align="justify">
|
||||
When run in a multi-threaded environment, incoming packets are handled
|
||||
by the function <tt>tcpip_input()</tt>, which takes the same arguments
|
||||
as the <tt>ip_input()</tt> function. The difference between the two
|
||||
functions is that the <tt>tcpip_input()</tt> function does not process
|
||||
the incoming packet immediately. It merely puts the packet on a queue
|
||||
which later is drained by the TCP/IP thread.
|
||||
</p>
|
||||
|
||||
<p align="justify">
|
||||
When being run in a multi-threaded system, timer events are taken care
|
||||
of internally in <tt>tcpip.c</tt>.

<h1>lwIP - A Lightweight TCP/IP Stack</h1>
|
||||
<p>
|
||||
The web page you are watching was served by a simple web
|
||||
server running on top of the lightweight TCP/IP stack <a
|
||||
href="http://www.sics.se/~adam/lwip/">lwIP</a>.
|
||||
</p>
|
||||
<p>
|
||||
lwIP is an open source implementation of the TCP/IP
|
||||
protocol suite that was originally written by <a
|
||||
href="http://www.sics.se/~adam/lwip/">Adam Dunkels
|
||||
of the Swedish Institute of Computer Science</a> but now is
|
||||
being actively developed by a team of developers
|
||||
distributed world-wide. Since it's release, lwIP has
|
||||
spurred a lot of interest and has been ported to several
|
||||
platforms and operating systems. lwIP can be used either
|
||||
with or without an underlying OS.
|
||||
</p>
|
||||
<p>
|
||||
The focus of the lwIP TCP/IP implementation is to reduce
|
||||
the RAM usage while still having a full scale TCP. This
|
||||
makes lwIP suitable for use in embedded systems with tens
|
||||
of kilobytes of free RAM and room for around 40 kilobytes
|
||||
of code ROM.
|
||||

Microsoft ResX Schema
|
||||
|
||||
Version 2.0
|
||||
|
||||
The primary goals of this format is to allow a simple XML format
|
||||
that is mostly human readable. The generation and parsing of the
|
||||
various data types are done through the TypeConverter classes
|
||||
associated with the data types.
|
||||
|
||||
Example:
|
||||
|
||||
... ado.net/XML headers & schema ...
|
||||
<resheader name="resmimetype">text/microsoft-resx</resheader>
|
||||
<resheader name="version">2.0</resheader>
|
||||
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
|
||||
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
|
||||
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
|
||||
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
|
||||
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
|
||||
<value>[base64 mime encoded serialized .NET Framework object]</value>
|
||||
</data>
|
||||
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
|
||||
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
|
||||
<comment>This is a comment</comment>
|
||||
</data>
|
||||
|
||||
There are any number of "resheader" rows that contain simple
|
||||
name/value pairs.
|
||||
|
||||
Each data row contains a name, and value. The row also contains a
|
||||
type or mimetype. Type corresponds to a .NET class that support
|
||||
text/value conversion through the TypeConverter architecture.
|
||||
Classes that don't support this are serialized and stored with the
|
||||
mimetype set.
|
||||
|
||||
The mimetype is used for serialized objects, and tells the
|
||||
ResXResourceReader how to depersist the object. This is currently not
|
||||
extensible. For a given mimetype the value must be set accordingly:
|
||||
|
||||
Note - application/x-microsoft.net.object.binary.base64 is the format
|
||||
that the ResXResourceWriter will generate, however the reader can
|
||||
read any of the formats listed below.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.binary.base64
|
||||
value : The object must be serialized with
|
||||
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
|
||||
: and then encoded with base64 encoding.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.soap.base64
|
||||
value : The object must be serialized with
|
||||
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
|
||||
: and then encoded with base64 encoding.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.bytearray.base64
|
||||
value : The object must be serialized into a byte array
|
||||
: using a System.ComponentModel.TypeConverter
|
||||
: and then encoded with base64 encoding.
