FreeModbus Coldfire MC523x PORT with lwIP
|
||||
|
||||
REQUIREMENTS
|
||||
============
|
||||
|
||||
The FreeModbus/lwIP port requires are port of the lwIP TCP/IP stack for
|
||||
the target platform. This port includes a suitable Ethernet driver for
|
||||
lwIP as well as a FreeRTOS port.
|
||||
The FreeModbus part itself does NOT depend on FreeRTOS or the Coldfire
|
||||
ethernet controller and can therefore be used for creating other ports.
|
||||
|
||||
The development environment used is based on the GNU C Compiler for
|
||||
a m68k-elf target as well as the insight debugger with some patches for
|
||||
the BDM interface[1]. GDB startup and linker scripts are supplied with
|
||||
the demo for the M5235BCC evaluation kit from Freescale.
|
||||
|
||||
[1] ... BDM tools: http://sourceforge.net/projects/bdm/
|
||||
|
||||
USAGE
|
||||
=====
|
||||
|
||||
A makefile is supplied with the demo application and a binary can be
|
||||
produced by calling 'make all'. A special target 'debug' is provided
|
||||
which executes the insight debugger. At the insight debugger prompt
|
||||
one should select the appropriate target interface (either BDM/Direct
|
||||
or BDM/TCP) and should download the application to the development
|
||||
board. It is important that the GDB script setup-and-load is executed
|
||||
prior to downloading to initialize the SDRAM. After downloading one
|
||||
should call the GDB function 'execute' and the PC is set to the start
|
||||
of the executable. Execution can be started by typing 'continue' at
|
||||
the Insight console interface.
|
||||
In addition it is possible to download the software to the flash. This can
|
||||
be done by calling 'make flash-erase' and 'make flash-programm'.
|
||||
|
||||
By default the port using the following settings:
|
||||
|
||||
IP Address : 10.0.10.2
|
||||
Netmask : 255.255.255.0
|
||||
Gateway : 10.0.10.1
|
||||
Modbus TCP Port : 502
|
||||
|
||||
COMMON PROBLEMS
|
||||
===============
|
||||
|
||||
Most of the problems have their origin in the startup scripts. The
|
||||
following list should serve as a checklist where each point must be
|
||||
satisfied for the port to work.
|
||||
|
||||
- The FreeRTOS port only works correctly in the supervisor mode. There-
|
||||
fore the Coldfire CPU must run in the supervisor mode.
|
||||
|
||||
- portVECTOR_TABLE does not point to the currently active vector table.
|
||||
Please also note that the vector table must be in RAM such that the
|
||||
FreeRTOS port can install a traphandler for the portYIELD() call.

|
||||
|
||||
* application code.
|
||||
|
||||
*
|

|

* xLists can only store pointers to xListItems. Each xListItem contains a

|

* descending item value order.
|

*
|
||||
|
||||
* Lists are created already containing one list item. The value of this
|
||||
|
||||
* item is the maximum possible that can be stored, it is therefore always at
|
||||
|
||||
* the end of the list and acts as a marker. The list member pxHead always
|
||||
|

* points to this marker - even though it is at the tail of the list. This
|
||||
|
||||
* is because the tail contains a wrap back pointer to the true head of

* the list.
|
||||
|
||||
*
|
||||
|
||||
* In addition to it's value, each list item contains a pointer to the next
|

|

* item in the list (pxNext), a pointer to the list it is in (pxContainer)
|
||||
|
||||
* and a pointer to back to the object that contains it. These later two
|
||||
|

* pointers are included for efficiency of list manipulation. There is

*
|

|

Changes from V1.2.0
|
||||
|
||||
|
||||
|
||||
+ Removed the volatile modifier from the function parameters. This was
|
||||
|
||||
only ever included to prevent compiler warnings. Now warnings are
|
||||
|
||||
removed by casting parameters where the calls are made.
|
||||
|
||||
|
||||
|
||||
+ prvListGetOwnerOfNextEntry() and prvListGetOwnerOfHeadEntry() have been
|
||||
|
||||
removed from the c file and added as macros to the h file.
|
||||
|
||||
|
||||
|
||||
+ uxNumberOfItems has been added to the list structure. This removes the
|
||||
|
||||
need for a pointer comparison when checking if a list is empty, and so
|
||||
|
||||
is slightly faster.
|
||||
|
||||
|
||||
|
||||
+ Removed the NULL check in vListRemove(). This makes the call faster but
|
||||
|
||||
necessitates any application code utilising the list implementation to
|
||||
|
||||
ensure NULL pointers are not passed.
|
||||
|
||||
|
||||
|
||||
Changes from V2.0.0
|
||||
|
||||
|
||||
|
||||
+ Double linked the lists to allow faster removal item removal.
|
||||
|
||||
|
||||
|
||||
Changes from V2.6.1
|
||||
|
||||
|
||||
|
||||
+ Make use of the new portBASE_TYPE definition where ever appropriate.
|
||||
|
||||
|
||||
|
||||
Changes from V3.0.0
|
||||
|
||||
|
||||
|
||||
+ API changes as described on the FreeRTOS.org WEB site.
|
||||
|
||||
|
||||
|
||||
Changes from V3.2.4
|
||||
|
||||
|
||||
|
||||
+ Removed the pxHead member of the xList structure. This always pointed
|
||||
|
||||
to the same place so has been removed to free a few bytes of RAM.
|
||||
|
||||
|
||||
|
||||
+ Introduced the xMiniListItem structure that does not include the
|
||||
|
||||
xListItem members that are not required by the xListEnd member of a list.
|
||||
|
||||
Again this was done to reduce RAM usage.
|
||||
|
||||
|
||||
|
||||
+ Changed the volatile definitions of some structure members to clean up
|
||||
|
||||
the code where the list structures are used.
|
||||
|
||||
|
||||
|
||||
Changes from V4.0.4
|
||||
|
||||
|
||||
|
||||
+ Optimised vListInsert() in the case when the wake time is the maximum
|
||||
|
||||
tick count value.

FUTURE
|
||||
|
||||
* TODO: The lwIP source code makes some invalid assumptions on processor
|
||||
word-length, storage sizes and alignment. See the mailing lists for
|
||||
problems with exoteric (/DSP) architectures showing these problems.
|
||||
We still have to fix some of these issues neatly.
|
||||
|
||||
* TODO: the ARP layer is not protected against concurrent access. If
|
||||
you run from a multitasking OS, serialize access to ARP (called from
|
||||
your network device driver and from a timeout thread.)
|
||||
|
||||
* TODO: the PPP code is broken in a few ways. There are namespace
|
||||
collisions on BSD systems and many assumptions on word-length
|
||||
(sizeof(int)). In ppp.c an assumption is made on the availability of
|
||||
a thread subsystem. Either PPP needs to be moved to contrib/ports/???
|
||||
or rearranged to be more generic.

HISTORY
|
||||
|
||||
(CVS HEAD)
|
||||
|
||||
* [New changes go here]
|
||||
|
||||
(STABLE-1_1_1)
|
||||
|
||||
2006-03-03 Christiaan Simons
|
||||
* ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
|
||||
access and added pbuf_alloc() return value checks.
|
||||
|
||||
2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
|
||||
now handled by the checksum routine properly.
|
||||
|
||||
2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* pbuf.c: Fix alignment; pbuf_init() would not work unless
|
||||
pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
|
||||
|
||||
2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
|
||||
submitted by Mitrani Hiroshi.
|
||||
|
||||
2005-12-15 Christiaan Simons
|
||||
* inet.c: Disabled the added summing routine to preserve code space.
|
||||
|
||||
2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
|
||||
Added Curt McDowell's optimized checksumming routine for future
|
||||
inclusion. Need to create test case for unaliged, aligned, odd,
|
||||
even length combination of cases on various endianess machines.
|
||||
|
||||
2005-12-09 Christiaan Simons
|
||||
* inet.c: Rewrote standard checksum routine in proper portable C.
|
||||
|
||||
2005-11-25 Christiaan Simons
|
||||
* udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
|
||||
* *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
|
||||
u32_t, s32_t typedefs. This solves most debug word-length assumes.
|
||||
|
||||
2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* inet.c: Fixed unaligned 16-bit access in the standard checksum
|
||||
routine by Peter Jolasson.
|
||||
* slipif.c: Fixed implementation assumption of single-pbuf datagrams.
|
||||
|
||||
2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
|
||||
* tcp_{out|in}.c: Applied patch fixing unaligned access.
|
||||
|
||||
2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
|
||||
|
||||
2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* udp.c: UDP pcb->recv() was called even when it was NULL.
|
||||
|
||||
(STABLE-1_1_0)
|
||||
|
||||
2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* etharp.*: Disabled multiple packets on the ARP queue.
|
||||
This clashes with TCP queueing.
|
||||
|
||||
2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* etharp.*: Fixed race condition from ARP request to ARP timeout.
|
||||
Halved the ARP period, doubled the period counts.
|
||||
ETHARP_MAX_PENDING now should be at least 2. This prevents
|
||||
the counter from reaching 0 right away (which would allow
|
||||
too little time for ARP responses to be received).
|
||||
|
||||
2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* dhcp.c: Decline messages were not multicast but unicast.
|
||||
* etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
|
||||
Do not try hard to insert arbitrary packet's source address,
|
||||
etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
|
||||
etharp_query() now always DOES call ETHARP_TRY_HARD so that users
|
||||
querying an address will see it appear in the cache (DHCP could
|
||||
suffer from this when a server invalidly gave an in-use address.)
|
||||
* ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
|
||||
comparing network addresses (identifiers), not the network masks
|
||||
themselves.
|
||||
* ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
|
||||
IP address actually belongs to the network of the given interface.
|
||||
|
||||
2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
|
||||
* tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
|
||||
|
||||
(STABLE-1_1_0-RC1)
|
||||
|
||||
2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
|
||||
* tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
|
||||
even if one is already pending, if the rcv_wnd is above a threshold
|
||||
(currently TCP_WND/2). This avoids waiting for a timer to expire to send a
|
||||
delayed ACK in order to open the window if the stack is only receiving data.
|
||||
|
||||
2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
|
||||
* tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
|
||||
|
||||
2004-08-20 Tony Mountifield <tony@softins.co.uk>
|
||||
* etharp.c: Make sure the first pbuf queued on an ARP entry
|
||||
is properly ref counted.
|
||||
|
||||
2004-07-27 Tony Mountifield <tony@softins.co.uk>
|
||||
* debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
|
||||
warnings about comparison.
|
||||
* pbuf.c: Stopped compiler complaining of empty if statement
|
||||
when LWIP_DEBUGF() empty. Closed an unclosed comment.
|
||||
* tcp.c: Stopped compiler complaining of empty if statement
|
||||
when LWIP_DEBUGF() empty.
|
||||
* ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
|
||||
* inet.c: Added a couple of casts to quiet the compiler.
|
||||
No need to test isascii(c) before isdigit(c) or isxdigit(c).
|
||||
|
||||
2004-07-22 Tony Mountifield <tony@softins.co.uk>
|
||||
* inet.c: Made data types consistent in inet_ntoa().
|
||||
Added casts for return values of checksum routines, to pacify compiler.
|
||||
* ip_frag.c, tcp_out.c, sockets.c, pbuf.c
|
||||
Small corrections to some debugging statements, to pacify compiler.
|
||||
|
||||
2004-07-21 Tony Mountifield <tony@softins.co.uk>
|
||||
* etharp.c: Removed spurious semicolon and added missing end-of-comment.
|
||||
* ethernetif.c Updated low_level_output() to match prototype for
|
||||
netif->linkoutput and changed low_level_input() similarly for consistency.
|
||||
* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
|
||||
of raw_recv() in raw.h and so avoid compiler error.
|
||||
* sockets.c: Added trivial (int) cast to keep compiler happier.
|
||||
* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
|
||||
|
||||
(STABLE-1_0_0)
|
||||
|
||||
++ Changes:
|
||||
|
||||
2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
|
||||
your cc.h file defines this either 1 or 0. If non-defined,
|
||||
defaults to 1.
|
||||
* .c: Added <string.h> and <errno.h> includes where used.
|
||||
* etharp.c: Made some array indices unsigned.
|
||||
|
||||
2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* netif.*: Added netif_set_up()/down().
|
||||
* dhcp.c: Changes to restart program flow.
|
||||
|
||||
2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* etharp.c: In find_entry(), instead of a list traversal per candidate, do a
|
||||
single-pass lookup for different candidates. Should exploit locality.
|
||||
|
||||
2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* tcp*.c: Cleaned up source comment documentation for Doxygen processing.
|
||||
* opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
|
||||
* etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
|
||||
the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
|
||||
suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
|
||||
non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
|
||||
is to prefix the 14-bit Ethernet headers with two padding bytes.
|
||||
|
||||
2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
|
||||
* ip_addr.c: Fix in the ip_addr_isbroadcast() check.
|
||||
* etharp.c: Fixed the case where the packet that initiates the ARP request
|
||||
is not queued, and gets lost. Fixed the case where the packets destination
|
||||
address is already known; we now always queue the packet and perform an ARP
|
||||
request.
|
||||
|
||||
(STABLE-0_7_0)
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
* Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
|
||||
* Fixed TCP bug in dequeueing of FIN from out of order segment queue.
|
||||
* Fixed two possible NULL references in rare cases.
|
||||
|
||||
(STABLE-0_6_6)
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
* Fixed DHCP which did not include the IP address in DECLINE messages.
|
||||
|
||||
++ Changes:
|
||||
|
||||
* etharp.c has been hauled over a bit.
|
||||
|
||||
(STABLE-0_6_5)
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
* Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
|
||||
* Packets sent from ARP queue had invalid source hardware address.
|
||||
|
||||
++ Changes:
|
||||
|
||||
* Pass-by ARP requests do now update the cache.
|
||||
|
||||
++ New features:
|
||||
|
||||
* No longer dependent on ctype.h.
|
||||
* New socket options.
|
||||
* Raw IP pcb support.
|
||||
|
||||
(STABLE-0_6_4)
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
* Some debug formatters and casts fixed.
|
||||
* Numereous fixes in PPP.
|
||||
|
||||
++ Changes:
|
||||
|
||||
* DEBUGF now is LWIP_DEBUGF
|
||||
* pbuf_dechain() has been re-enabled.
|
||||
* Mentioned the changed use of CVS branches in README.
|
||||
|
||||
(STABLE-0_6_3)
|
||||
|
||||
++ Bug fixes:
|
||||
|
||||
* Fixed pool pbuf memory leak in pbuf_alloc().
|
||||
Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
|
||||
Reported by Savin Zlobec.
|
||||
|
||||
* PBUF_POOL chains had their tot_len field not set for non-first
|
||||
pbufs. Fixed in pbuf_alloc().
|
||||
|
||||
++ New features:
|
||||
|
||||
* Added PPP stack contributed by Marc Boucher
|
||||
|
||||
++ Changes:
|
||||
|
||||
* Now drops short packets for ICMP/UDP/TCP protocols. More robust.
|
||||
|
||||
* ARP queueuing now queues the latest packet instead of the first.
|
||||
This is the RFC recommended behaviour, but can be overridden in
|
||||
lwipopts.h.
|
||||
|
||||
(0.6.2)
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* TCP has been fixed to deal with the new use of the pbuf->ref
|
||||
counter.
|
||||
|
||||
* DHCP dhcp_inform() crash bug fixed.
|
||||
|
||||
++ Changes:
|
||||
|
||||
* Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
|
||||
pbuf_refresh(). This has sped up pbuf pool operations considerably.
|
||||
Implemented by David Haas.
|
||||
|
||||
(0.6.1)
|
||||
|
||||
++ New features:
|
||||
|
||||
* The packet buffer implementation has been enhanced to support
|
||||
zero-copy and copy-on-demand for packet buffers which have their
|
||||
payloads in application-managed memory.
|
||||
Implemented by David Haas.
|
||||
|
||||
Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
|
||||
if an outgoing packet can be directly sent on the link, or perform
|
||||
a copy-on-demand when necessary.
|
||||
|
||||
The application can safely assume the packet is sent, and the RAM
|
||||
is available to the application directly after calling udp_send()
|
||||
or similar function.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* ARP_QUEUEING should now correctly work for all cases, including
|
||||
PBUF_REF.
|
||||
Implemented by Leon Woestenberg.
|
||||
|
||||
++ Changes:
|
||||
|
||||
* IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
|
||||
to a '0.0.0.0' IP address.
|
||||
|
||||
* The packet buffer implementation is changed. The pbuf->ref counter
|
||||
meaning has changed, and several pbuf functions have been
|
||||
adapted accordingly.
|
||||
|
||||
* netif drivers have to be changed to set the hardware address length field
|
||||
that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
|
||||
See the contrib/ports/c16x cs8900 driver as a driver example.
|
||||
|
||||
* netif's have a dhcp field that must be initialized to NULL by the driver.
|
||||
See the contrib/ports/c16x cs8900 driver as a driver example.
|
||||
|
||||
(0.5.x) This file has been unmaintained up to 0.6.1. All changes are
|
||||
logged in CVS but have not been explained here.
|
||||
|
||||
(0.5.3) Changes since version 0.5.2
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* memp_malloc(MEMP_API_MSG) could fail with multiple application
|
||||
threads because it wasn't protected by semaphores.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* struct ip_addr now packed.
|
||||
|
||||
* The name of the time variable in arp.c has been changed to ctime
|
||||
to avoid conflicts with the time() function.
|
||||
|
||||
(0.5.2) Changes since version 0.5.1
|
||||
|
||||
++ New features:
|
||||
|
||||
* A new TCP function, tcp_tmr(), now handles both TCP timers.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* A bug in tcp_parseopt() could cause the stack to hang because of a
|
||||
malformed TCP option.
|
||||
|
||||
* The address of new connections in the accept() function in the BSD
|
||||
socket library was not handled correctly.
|
||||
|
||||
* pbuf_dechain() did not update the ->tot_len field of the tail.
|
||||
|
||||
* Aborted TCP connections were not handled correctly in all
|
||||
situations.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* All protocol header structs are now packed.
|
||||
|
||||
* The ->len field in the tcp_seg structure now counts the actual
|
||||
amount of data, and does not add one for SYN and FIN segments.
|
||||
|
||||
(0.5.1) Changes since version 0.5.0
|
||||
|
||||
++ New features:
|
||||
|
||||
* Possible to run as a user process under Linux.
|
||||
|
||||
* Preliminary support for cross platform packed structs.
|
||||
|
||||
* ARP timer now implemented.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* TCP output queue length was badly initialized when opening
|
||||
connections.
|
||||
|
||||
* TCP delayed ACKs were not sent correctly.
|
||||
|
||||
* Explicit initialization of BSS segment variables.
|
||||
|
||||
* read() in BSD socket library could drop data.
|
||||
|
||||
* Problems with memory alignment.
|
||||
|
||||
* Situations when all TCP buffers were used could lead to
|
||||
starvation.
|
||||
|
||||
* TCP MSS option wasn't parsed correctly.
|
||||
|
||||
* Problems with UDP checksum calculation.
|
||||
|
||||
* IP multicast address tests had endianess problems.
|
||||
|
||||
* ARP requests had wrong destination hardware address.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* struct eth_addr changed from u16_t[3] array to u8_t[6].
|
||||
|
||||
* A ->linkoutput() member was added to struct netif.
|
||||
|
||||
* TCP and UDP ->dest_* struct members where changed to ->remote_*.
|
||||
|
||||
* ntoh* macros are now null definitions for big endian CPUs.
|
||||
|
||||
(0.5.0) Changes since version 0.4.2
|
||||
|
||||
++ New features:
|
||||
|
||||
* Redesigned operating system emulation layer to make porting easier.
|
||||
|
||||
* Better control over TCP output buffers.
|
||||
|
||||
* Documenation added.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* Locking issues in buffer management.
|
||||
|
||||
* Bugfixes in the sequential API.
|
||||
|
||||
* IP forwarding could cause memory leakage. This has been fixed.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* Directory structure somewhat changed; the core/ tree has been
|
||||
collapsed.
|
||||
|
||||
(0.4.2) Changes since version 0.4.1
|
||||
|
||||
++ New features:
|
||||
|
||||
* Experimental ARP implementation added.
|
||||
|
||||
* Skeleton Ethernet driver added.
|
||||
|
||||
* Experimental BSD socket API library added.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* In very intense situations, memory leakage could occur. This has
|
||||
been fixed.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* Variables named "data" and "code" have been renamed in order to
|
||||
avoid name conflicts in certain compilers.
|
||||
|
||||
* Variable++ have in appliciable cases been translated to ++variable
|
||||
since some compilers generate better code in the latter case.
|
||||
|
||||
(0.4.1) Changes since version 0.4
|
||||
|
||||
++ New features:
|
||||
|
||||
* TCP: Connection attempts time out earlier than data
|
||||
transmissions. Nagle algorithm implemented. Push flag set on the
|
||||
last segment in a burst.
|
||||
|
||||
* UDP: experimental support for UDP-Lite extensions.
|
||||
|
||||
++ Bugfixes:
|
||||
|
||||
* TCP: out of order segments were in some cases handled incorrectly,
|
||||
and this has now been fixed. Delayed acknowledgements was broken
|
||||
in 0.4, has now been fixed. Binding to an address that is in use
|
||||
now results in an error. Reset connections sometimes hung an
|
||||
application; this has been fixed.
|
||||
|
||||
* Checksum calculation sometimes failed for chained pbufs with odd
|
||||
lengths. This has been fixed.
|
||||
|
||||
* API: a lot of bug fixes in the API. The UDP API has been improved
|
||||
and tested. Error reporting and handling has been
|
||||
improved. Logical flaws and race conditions for incoming TCP
|
||||
connections has been found and removed.
|
||||
|
||||
* Memory manager: alignment issues. Reallocating memory sometimes
|
||||
failed, this has been fixed.
|
||||
|
||||
* Generic library: bcopy was flawed and has been fixed.
|
||||
|
||||
++ Other changes:
|
||||
|
||||
* API: all datatypes has been changed from generic ones such as
|
||||
ints, to specified ones such as u16_t. Functions that return
|
||||
errors now have the correct type (err_t).
|
||||
|
||||
* General: A lot of code cleaned up and debugging code removed. Many
|
||||
portability issues have been fixed.
|
||||
|
||||
* The license was changed; the advertising clause was removed.
|
||||
|
||||
* C64 port added.
|
||||
|
||||
* Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
|
||||
Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
|
||||
fixing bugs!
|
||||
|
||||
(0.4) Changes since version 0.3.1
|
||||
|
||||
* Memory management has been radically changed; instead of
|
||||
allocating memory from a shared heap, memory for objects that are
|
||||
rapidly allocated and deallocated is now kept in pools. Allocation
|
||||
and deallocation from those memory pools is very fast. The shared
|
||||
heap is still present but is used less frequently.
|
||||
|
||||
* The memory, memory pool, and packet buffer subsystems now support
|
||||
4-, 2-, or 1-byte alignment.
|
||||
|
||||
* "Out of memory" situations are handled in a more robust way.
|
||||
|
||||
* Stack usage has been reduced.
|
||||
|
||||
* Easier configuration of lwIP parameters such as memory usage,
|
||||
TTLs, statistics gathering, etc. All configuration parameters are
|
||||
now kept in a single header file "lwipopts.h".
|
||||
|
||||
* The directory structure has been changed slightly so that all
|
||||
architecture specific files are kept under the src/arch
|
||||
hierarchy.
|
||||
|
||||
* Error propagation has been improved, both in the protocol modules
|
||||
and in the API.
|
||||
|
||||
* The code for the RTXC architecture has been implemented, tested
|
||||
and put to use.
|
||||
|
||||
* Bugs have been found and corrected in the TCP, UDP, IP, API, and
|
||||
the Internet checksum modules.
|
||||
|
||||
* Bugs related to porting between a 32-bit and a 16-bit architecture
|
||||
have been found and corrected.
|
||||
|
||||
* The license has been changed slightly to conform more with the
|
||||
original BSD license, including the advertisement clause.
|
||||
|
||||
(0.3.1) Changes since version 0.3
|
||||
|
||||
* Fix of a fatal bug in the buffer management. Pbufs with allocated
|
||||
RAM never returned the RAM when the pbuf was deallocated.
|
||||
|
||||
* TCP congestion control, window updates and retransmissions did not
|
||||
work correctly. This has now been fixed.
|
||||
|
||||
* Bugfixes in the API.
|
||||
|
||||
(0.3) Changes since version 0.2
|
||||
|
||||
* New and improved directory structure. All include files are now
|
||||
kept in a dedicated include/ directory.
|
||||
|
||||
* The API now has proper error handling. A new function,
|
||||
netconn_err(), now returns an error code for the connection in
|
||||
case of errors.
|
||||
|
||||
* Improvements in the memory management subsystem. The system now
|
||||
keeps a pointer to the lowest free memory block. A new function,
|
||||
mem_malloc2() tries to allocate memory once, and if it fails tries
|
||||
to free some memory and retry the allocation.
|
||||
|
||||
* Much testing has been done with limited memory
|
||||
configurations. lwIP now does a better job when overloaded.
|
||||
|
||||
* Some bugfixes and improvements to the buffer (pbuf) subsystem.
|
||||
|
||||
* Many bugfixes in the TCP code:
|
||||
|
||||
- Fixed a bug in tcp_close().
|
||||
|
||||
- The TCP receive window was incorrectly closed when out of
|
||||
sequence segments was received. This has been fixed.
|
||||
|
||||
- Connections are now timed-out of the FIN-WAIT-2 state.
|
||||
|
||||
- The initial congestion window could in some cases be too
|
||||
large. This has been fixed.
|
||||
|
||||
- The retransmission queue could in some cases be screwed up. This
|
||||
has been fixed.
|
||||
|
||||
- TCP RST flag now handled correctly.
|
||||
|
||||
- Out of sequence data was in some cases never delivered to the
|
||||
application. This has been fixed.
|
||||
|
||||
- Retransmitted segments now contain the correct acknowledgment
|
||||
number and advertised window.
|
||||
|
||||
- TCP retransmission timeout backoffs are not correctly computed
|
||||
(ala BSD). After a number of retransmissions, TCP now gives up
|
||||
the connection.
|
||||
|
||||
* TCP connections now are kept on three lists, one for active
|
||||
connections, one for listening connections, and one for
|
||||
connections that are in TIME-WAIT. This greatly speeds up the fast
|
||||
timeout processing for sending delayed ACKs.
|
||||
|
||||
* TCP now provides proper feedback to the application when a
|
||||
connection has been successfully set up.
|
||||
|
||||
* More comments have been added to the code. The code has also been
|
||||
somewhat cleaned up.
|
||||
|
||||
(0.2) Initial public release.

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
|
||||
* UDP (User Datagram Protocol) including experimental UDP-lite
|
||||
extensions
|
||||
* TCP (Transmission Control Protocol) with congestion control, RTT
|
||||
estimation and fast recovery/fast retransmit
|
||||
* Specialized API for enhanced performance
|
||||
* Optional Berkeley socket API
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
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, CVS and the
|
||||
mailing list. A core team of developers will commit changes to the
|
||||
CVS source tree.
|
||||
|
||||
The lwIP TCP/IP stack is maintained in the 'lwip' CVS module and
|
||||
contributions (such as platform ports) are in the 'contrib' module.
|
||||
|
||||
See doc/savannah.txt for details on CVS server access for users and
|
||||
developers.
|
||||
|
||||
Last night's CVS tar ball can be downloaded from:
|
||||
http://savannah.gnu.org/cvs.backups/lwip.tar.gz [CHANGED - NEEDS FIXING]
|
||||
|
||||
The current CVS trees are web-browsable:
|
||||
http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
|
||||
http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/contrib/
|
||||
|
||||
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 CVS sources and is available from this web page:
|
||||
http://www.nongnu.org/lwip/
|
||||
|
||||
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.

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. 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 CVS 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. Trivial patches (compiler warning, indentation and spelling fixes or anything obvious which takes a line or two)
|
||||
can go to the lwip-users list. This is still the fastest way of interaction and the list is not so crowded
|
||||
as to allow for loss of fixes. Putting bugs on Savannah and subsequently closing them is too much an overhead
|
||||
for reporting a compiler warning fix.
|
||||
6. 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 CVS access to submit and maintain your port in the contrib CVS module.

|
||||
Raw TCP/IP interface for lwIP
|
||||
|
||||
Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons
|
||||
|
||||
lwIP provides two 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.
|
||||
|
||||
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
|
||||
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 remainder of this document discusses the "raw" API. **
|
||||
|
||||
The raw TCP/IP interface allows the application program to integrate
|
||||
better with the TCP/IP code. Program execution is event based by
|
||||
having callback functions being called from within the TCP/IP
|
||||
code. The TCP/IP code and the application program both run in the same
|
||||
thread. The sequential API has a much higher overhead and is not very
|
||||
well suited for small systems since it forces a multithreaded paradigm
|
||||
on the application.
|
||||
|
||||
The raw TCP/IP interface is not only faster in terms of code execution
|
||||
time but is also less memory intensive. The drawback is that program
|
||||
development is somewhat harder and application programs written for
|
||||
the raw TCP/IP interface are more difficult to understand. Still, this
|
||||
is the preferred way of writing applications that should be small in
|
||||
code size and memory usage.
|
||||
|
||||
Both APIs can be used simultaneously by different application
|
||||
programs. In fact, the sequential API is implemented as an application
|
||||
program using the raw TCP/IP interface.
|
||||
|
||||
--- Callbacks
|
||||
|
||||
Program execution is driven by callbacks. Each callback is an ordinary
|
||||
C function that is called from within the TCP/IP code. Every callback
|
||||
function is passed the current TCP or UDP connection state as an
|
||||
argument. Also, in order to be able to keep program specific state,
|
||||
the callback functions are called with a program specified argument
|
||||
that is independent of the TCP/IP state.
|
||||
|
||||
The function for setting the application connection state is:
|
||||
|
||||
- void tcp_arg(struct tcp_pcb *pcb, void *arg)
|
||||
|
||||
Specifies the program specific state that should be passed to all
|
||||
other callback functions. The "pcb" argument is the current TCP
|
||||
connection control block, and the "arg" argument is the argument
|
||||
that will be passed to the callbacks.
|
||||
|
||||
|
||||
--- TCP connection setup
|
||||
|
||||
The functions used for setting up connections is similar to that of
|
||||
the sequential API and of the BSD socket API. A new TCP connection
|
||||
identifier (i.e., a protocol control block - PCB) is created with the
|
||||
tcp_new() function. This PCB can then be either set to listen for new
|
||||
incoming connections or be explicitly connected to another host.
|
||||
|
||||
- struct tcp_pcb *tcp_new(void)
|
||||
|
||||
Creates a new connection identifier (PCB). If memory is not
|
||||
available for creating the new pcb, NULL is returned.
|
||||
|
||||
- err_t tcp_bind(struct tcp_pcb *pcb, struct ip_addr *ipaddr,
|
||||
u16_t port)
|
||||
|
||||
Binds the pcb to a local IP address and port number. The IP address
|
||||
can be specified as IP_ADDR_ANY in order to bind the connection to
|
||||
all local IP addresses.
|
||||
|
||||
If another connection is bound to the same port, the function will
|
||||
return ERR_USE, otherwise ERR_OK is returned.
|
||||
|
||||
- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb)
|
||||
|
||||
Commands a pcb to start listening for incoming connections. When an
|
||||
incoming connection is accepted, the function specified with the
|
||||
tcp_accept() function will be called. The pcb will have to be bound
|
||||
to a local port with the tcp_bind() function.
|
||||
|
||||
The tcp_listen() function returns a new connection identifier, and
|
||||
the one passed as an argument to the function will be
|
||||
deallocated. The reason for this behavior is that less memory is
|
||||
needed for a connection that is listening, so tcp_listen() will
|
||||
reclaim the memory needed for the original connection and allocate a
|
||||
new smaller memory block for the listening connection.
|
||||
|
||||
tcp_listen() may return NULL if no memory was available for the
|
||||
listening connection. If so, the memory associated with the pcb
|
||||
passed as an argument to tcp_listen() will not be deallocated.
|
||||
|
||||
- void tcp_accept(struct tcp_pcb *pcb,
|
||||
err_t (* accept)(void *arg, struct tcp_pcb *newpcb,
|
||||
err_t err))
|
||||
|
||||
Specified the callback function that should be called when a new
|
||||
connection arrives on a listening connection.
|
||||
|
||||
- err_t tcp_connect(struct tcp_pcb *pcb, struct ip_addr *ipaddr,
|
||||
u16_t port, err_t (* connected)(void *arg,
|
||||
struct tcp_pcb *tpcb,
|
||||
err_t err));
|
||||
|
||||
Sets up the pcb to connect to the remote host and sends the
|
||||
initial SYN segment which opens the connection.
|
||||
|
||||
The tcp_connect() function returns immediately; it does not wait for
|
||||
the connection to be properly setup. Instead, it will call the
|
||||
function specified as the fourth argument (the "connected" argument)
|
||||
when the connection is established. If the connection could not be
|
||||
properly established, either because the other host refused the
|
||||
connection or because the other host didn't answer, the "connected"
|
||||
function will be called with an the "err" argument set accordingly.
|
||||
|
||||
The tcp_connect() function can return ERR_MEM if no memory is
|
||||
available for enqueueing the SYN segment. If the SYN indeed was
|
||||
enqueued successfully, the tcp_connect() function returns ERR_OK.
|
||||
|
||||
|
||||
--- Sending TCP data
|
||||
|
||||
TCP data is sent by enqueueing the data with a call to
|
||||
tcp_write(). When the data is successfully transmitted to the remote
|
||||
host, the application will be notified with a call to a specified
|
||||
callback function.
|
||||
|
||||
- err_t tcp_write(struct tcp_pcb *pcb, void *dataptr, u16_t len,
|
||||
u8_t copy)
|
||||
|
||||
Enqueues the data pointed to by the argument dataptr. The length of
|
||||
the data is passed as the len parameter. The copy argument is either
|
||||
0 or 1 and indicates whether the new memory should be allocated for
|
||||
the data to be copied into. If the argument is 0, no new memory
|
||||
should be allocated and the data should only be referenced by
|
||||
pointer.
|
||||
|
||||
The tcp_write() function will fail and return ERR_MEM if the length
|
||||
of the data exceeds the current send buffer size or if the length of
|
||||
the queue of outgoing segment is larger than the upper limit defined
|
||||
in lwipopts.h. The number of bytes available in the output queue can
|
||||
be retrieved with the tcp_sndbuf() function.
|
||||
|
||||
The proper way to use this function is to call the function with at
|
||||
most tcp_sndbuf() bytes of data. If the function returns ERR_MEM,
|
||||
the application should wait until some of the currently enqueued
|
||||
data has been successfully received by the other host and try again.
|
||||
|
||||
- void tcp_sent(struct tcp_pcb *pcb,
|
||||
err_t (* sent)(void *arg, struct tcp_pcb *tpcb,
|
||||
u16_t len))
|
||||
|
||||
Specifies the callback function that should be called when data has
|
||||
successfully been received (i.e., acknowledged) by the remote
|
||||
host. The len argument passed to the callback function gives the
|
||||
amount bytes that was acknowledged by the last acknowledgment.
|
||||
|
||||
|
||||
--- Receiving TCP data
|
||||
|
||||
TCP data reception is callback based - an application specified
|
||||
callback function is called when new data arrives. When the
|
||||
application has taken the data, it has to call the tcp_recved()
|
||||
function to indicate that TCP can advertise increase the receive
|
||||
window.
|
||||
|
||||
- void tcp_recv(struct tcp_pcb *pcb,
|
||||
err_t (* recv)(void *arg, struct tcp_pcb *tpcb,
|
||||
struct pbuf *p, err_t err))
|
||||
|
||||
Sets the callback function that will be called when new data
|
||||
arrives. The callback function will be passed a NULL pbuf to
|
||||
indicate that the remote host has closed the connection.
|
||||
|
||||
- void tcp_recved(struct tcp_pcb *pcb, u16_t len)
|
||||
|
||||
Must be called when the application has received the data. The len
|
||||
argument indicates the length of the received data.
|
||||
|
||||
|
||||
--- Application polling
|
||||
|
||||
When a connection is idle (i.e., no data is either transmitted or
|
||||
received), lwIP will repeatedly poll the application by calling a
|
||||
specified callback function. This can be used either as a watchdog
|
||||
timer for killing connections that have stayed idle for too long, or
|
||||
as a method of waiting for memory to become available. For instance,
|
||||
if a call to tcp_write() has failed because memory wasn't available,
|
||||
the application may use the polling functionality to call tcp_write()
|
||||
again when the connection has been idle for a while.
|
||||
|
||||
- void tcp_poll(struct tcp_pcb *pcb, u8_t interval,
|
||||
err_t (* poll)(void *arg, struct tcp_pcb *tpcb))
|
||||
|
||||
Specifies the polling interval and the callback function that should
|
||||
be called to poll the application. The interval is specified in
|
||||
number of TCP coarse grained timer shots, which typically occurs
|
||||
twice a second. An interval of 10 means that the application would
|
||||
be polled every 5 seconds.
|
||||
|
||||
|
||||
--- Closing and aborting connections
|
||||
|
||||
- err_t tcp_close(struct tcp_pcb *pcb)
|
||||
|
||||
Closes the connection. The function may return ERR_MEM if no memory
|
||||
was available for closing the connection. If so, the application
|
||||
should wait and try again either by using the acknowledgment
|
||||
callback or the polling functionality. If the close succeeds, the
|
||||
function returns ERR_OK.
|
||||
|
||||
The pcb is deallocated by the TCP code after a call to tcp_close().
|
||||
|
||||
- void tcp_abort(struct tcp_pcb *pcb)
|
||||
|
||||
Aborts the connection by sending a RST (reset) segment to the remote
|
||||
host. The pcb is deallocated. This function never fails.
|
||||
|
||||
If a connection is aborted because of an error, the application is
|
||||
alerted of this event by the err callback. Errors that might abort a
|
||||
connection are when there is a shortage of memory. The callback
|
||||
function to be called is set using the tcp_err() function.
|
||||
|
||||
- void tcp_err(struct tcp_pcb *pcb, void (* err)(void *arg,
|
||||
err_t err))
|
||||
|
||||
The error callback function does not get the pcb passed to it as a
|
||||
parameter since the pcb may already have been deallocated.
|
||||
|
||||
|
||||
--- Lower layer TCP interface
|
||||
|
||||
TCP provides a simple interface to the lower layers of the
|
||||
system. During system initialization, the function tcp_init() has
|
||||
to be called before any other TCP function is called. When the system
|
||||
is running, the two timer functions tcp_fasttmr() and tcp_slowtmr()
|
||||
must be called with regular intervals. The tcp_fasttmr() should be
|
||||
called every TCP_FAST_INTERVAL milliseconds (defined in tcp.h) and
|
||||
tcp_slowtmr() should be called every TCP_SLOW_INTERVAL milliseconds.
|
||||
|
||||
|
||||
--- UDP interface
|
||||
|
||||
The UDP interface is similar to that of TCP, but due to the lower
|
||||
level of complexity of UDP, the interface is significantly simpler.
|
||||
|
||||
- struct udp_pcb *udp_new(void)
|
||||
|
||||
Creates a new UDP pcb which can be used for UDP communication. The
|
||||
pcb is not active until it has either been bound to a local address
|
||||
or connected to a remote address.
|
||||
|
||||
- void udp_remove(struct udp_pcb *pcb)
|
||||
|
||||
Removes and deallocates the pcb.
|
||||
|
||||
- err_t udp_bind(struct udp_pcb *pcb, struct ip_addr *ipaddr,
|
||||
u16_t port)
|
||||
|
||||
Binds the pcb to a local address. The IP-address argument "ipaddr"
|
||||
can be IP_ADDR_ANY to indicate that it should listen to any local IP
|
||||
address. The function currently always return ERR_OK.
|
||||
|
||||
- err_t udp_connect(struct udp_pcb *pcb, struct ip_addr *ipaddr,
|
||||
u16_t port)
|
||||
|
||||
Sets the remote end of the pcb. This function does not generate any
|
||||
network traffic, but only set the remote address of the pcb.
|
||||
|
||||
- err_t udp_disconnect(struct udp_pcb *pcb)
|
||||
|
||||
Remove the remote end of the pcb. This function does not generate
|
||||
any network traffic, but only removes the remote address of the pcb.
|
||||
|
||||
- err_t udp_send(struct udp_pcb *pcb, struct pbuf *p)
|
||||
|
||||
Sends the pbuf p. The pbuf is not deallocated.
|
||||
|
||||
- void udp_recv(struct udp_pcb *pcb,
|
||||
void (* recv)(void *arg, struct udp_pcb *upcb,
|
||||
struct pbuf *p,
|
||||
struct ip_addr *addr,
|
||||
u16_t port),
|
||||
void *recv_arg)
|
||||
|
||||
Specifies a callback function that should be called when a UDP
|
||||
datagram is received.
|
||||
|
||||
|
||||
--- System initalization
|
||||
|
||||
A truly complete and generic sequence for initializing the lwip stack
|
||||
cannot be given because it depends on the build configuration (lwipopts.h)
|
||||
and 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:
|
||||
|
||||
- stats_init()
|
||||
|
||||
Clears the structure where runtime statistics are gathered.
|
||||
|
||||
- sys_init()
|
||||
|
||||
Not of much use since we set the NO_SYS 1 option in lwipopts.h,
|
||||
to be called for easy configuration changes.
|
||||
|
||||
- mem_init()
|
||||
|
||||
Initializes the dynamic memory heap defined by MEM_SIZE.
|
||||
|
||||
- memp_init()
|
||||
|
||||
Initializes the memory pools defined by MEMP_NUM_x.
|
||||
|
||||
- pbuf_init()
|
||||
|
||||
Initializes the pbuf memory pool defined by PBUF_POOL_SIZE.
|
||||
|
||||
- etharp_init()
|
||||
|
||||
Initializes the ARP table and queue.
|
||||
Note: you must call etharp_tmr at a 10 second regular interval
|
||||
after this initialization.
|
||||
|
||||
- ip_init()
|
||||
|
||||
Doesn't do much, it should be called to handle future changes.
|
||||
|
||||
- udp_init()
|
||||
|
||||
Clears the UDP PCB list.
|
||||
|
||||
- tcp_init()
|
||||
|
||||
Clears the TCP PCB list and clears some internal TCP timers.
|
||||
Note: you must call tcp_fasttmr() and tcp_slowtmr() at the
|
||||
predefined regular intervals after this initialization.
|
||||
|
||||
- netif_add(struct netif *netif, struct ip_addr *ipaddr,
|
||||
struct ip_addr *netmask, struct ip_addr *gw,
|
||||
void *state, err_t (* init)(struct netif *netif),
|
||||
err_t (* input)(struct pbuf *p, struct netif *netif))
|
||||
|
||||
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 it's use.
|
||||
|
||||
err_t netif_if_init(struct netif *netif)
|
||||
{
|
||||
u8_t i;
|
||||
|
||||
for(i = 0; i < 6; i++) netif->hwaddr[i] = some_eth_addr[i];
|
||||
init_my_eth_device();
|
||||
return ERR_OK;
|
||||
}
|
||||
|
||||
The input function pointer must point to the lwip ip_input().
|
||||
|
||||
- netif_set_default(struct netif *netif)
|
||||
|
||||
Registers the default network interface.
|
||||
|
||||
- netif_set_up(struct netif *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.
|
||||
Note: you must call dhcp_fine_tmr() and dhcp_coarse_tmr() at
|
||||
the predefined regular intervals after starting the client.
|
||||
|
||||
You can peek in the netif->dhcp struct for the actual DHCP status.

|
||||
1 Obtaining lwIP from the CVS repository
|
||||
----------------------------------------
|
||||
|
||||
To perform an anonymous CVS checkout of the main trunk (this is where
|
||||
bug fixes and incremental enhancements occur), do this:
|
||||
|
||||
cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout lwip
|
||||
|
||||
Or, obtain a stable branch (updated with bug fixes only) as follows:
|
||||
cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
|
||||
-r STABLE-0_7 -d lwip-0.7 lwip
|
||||
|
||||
Or, obtain a specific (fixed) release as follows:
|
||||
cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
|
||||
-r STABLE-0_7_0 -d lwip-0.7.0 lwip
|
||||
|
||||
3 Committers/developers CVS access using SSH
|
||||
--------------------------------------------
|
||||
|
||||
The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption.
|
||||
As such, CVS 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@cvs.sv.gnu.org
|
||||
|
||||
If it tells you:
|
||||
|
||||
Authenticating with public key "your_key_name"...
|
||||
Server refused to allocate pty
|
||||
|
||||
then you could login; Savannah refuses to give you a shell - which is OK, as we
|
||||
are allowed to use SSH for CVS only. Now, you should be able to do this:
|
||||
|
||||
export CVS_RSH=ssh
|
||||
cvs -z3 -d:ext:your_login@cvs.sv.gnu.org:/sources/lwip co lwip
|
||||
|
||||
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 CVS 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 http://savannah.nongnu.org/cvs/?group=lwip)
|
||||
|
||||
|
||||
3 Merging from DEVEL branch to main trunk (stable)
|
||||
--------------------------------------------------
|
||||
|
||||
Merging is a delicate process in CVS and requires the
|
||||
following disciplined steps in order to prevent conflicts
|
||||
in the future. Conflicts can be hard to solve!
|
||||
|
||||
Merging from branch A to branch B requires that the A branch
|
||||
has a tag indicating the previous merger. This tag is called
|
||||
'merged_from_A_to_B'. After merging, the tag is moved in the
|
||||
A branch to remember this merger for future merge actions.
|
||||
|
||||
IMPORTANT: AFTER COMMITTING A SUCCESFUL MERGE IN THE
|
||||
REPOSITORY, THE TAG MUST BE SET ON THE SOURCE BRANCH OF THE
|
||||
MERGE ACTION (REPLACING EXISTING TAGS WITH THE SAME NAME).
|
||||
|
||||
Merge all changes in DEVEL since our last merge to main:
|
||||
|
||||
In the working copy of the main trunk:
|
||||
cvs update -P -jmerged_from_DEVEL_to_main -jDEVEL
|
||||
|
||||
(This will apply the changes between 'merged_from_DEVEL_to_main'
|
||||
and 'DEVEL' to your work set of files)
|
||||
|
||||
We can now commit the merge result.
|
||||
cvs commit -R -m "Merged from DEVEL to main."
|
||||
|
||||
If this worked out OK, we now move the tag in the DEVEL branch
|
||||
to this merge point, so we can use this point for future merges:
|
||||
|
||||
cvs rtag -F -r DEVEL merged_from_DEVEL_to_main lwip
|
||||
|
||||
4 How to release lwIP
|
||||
---------------------
|
||||
|
||||
First, checkout a clean copy of the branch to be released. Tag this set with
|
||||
tag name "STABLE-0_6_3". (I use release number 0.6.3 throughout this example).
|
||||
|
||||
Login CVS using pserver authentication, then export a clean copy of the
|
||||
tagged tree. Export is similar to a checkout, except that the CVS metadata
|
||||
is not created locally.
|
||||
|
||||
export CVS_RSH=ssh
|
||||
cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
|
||||
-r STABLE-0_6_3 -d lwip-0.6.3 lwip
|
||||
|
||||
Archive this directory using tar, gzip'd, bzip2'd and zip'd.
|
||||
|
||||
tar czvf lwip-0.6.3.tar.gz lwip-0.6.3
|
||||
tar cjvf lwip-0.6.3.tar.bz2 lwip-0.6.3
|
||||
zip -r lwip-0.6.3.zip lwip-0.6.3
|
||||
|
||||
Now, sign the archives with a detached GPG binary signature as follows:
|
||||
|
||||
gpg -b lwip-0.6.3.tar.gz
|
||||
gpg -b lwip-0.6.3.tar.bz2
|
||||
gpg -b lwip-0.6.3.zip
|
||||
|
||||
Upload these files using anonymous FTP:
|
||||
ncftp ftp://savannah.gnu.org/incoming/savannah/lwip
|
||||
|
||||
ncftp>mput *0.6.3.*
|
||||
|
||||
Additionally, you may post a news item on Savannah, like this:
|
||||
|
||||
A new 0.6.3 release is now available here:
|
||||
http://savannah.nongnu.org/files/?group=lwip&highlight=0.6.3
|
||||
|
||||
You will have to submit this via the user News interface, then approve
|
||||
this via the Administrator News interface.

sys_arch interface for lwIP 0.6++
|
||||
|
||||
Author: Adam Dunkels
|
||||
|
||||
The operating system emulation layer provides a common interface
|
||||
between the lwIP code and the underlying operating system kernel. The
|
||||
general idea is that porting lwIP to new architectures requires only
|
||||
small changes to a few header files and a new sys_arch
|
||||
implementation. It is also possible to do a sys_arch implementation
|
||||
that does not rely on any underlying operating system.
|
||||
|
||||
The sys_arch provides semaphores and mailboxes to lwIP. For the full
|
||||
lwIP functionality, multiple threads support can be implemented in the
|
||||
sys_arch, but this is not required for the basic lwIP
|
||||
functionality. Previous versions of lwIP required the sys_arch to
|
||||
implement timer scheduling as well but as of lwIP 0.5 this is
|
||||
implemented in a higher layer.
|
||||
|
||||
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.
|
||||
|
||||
Semaphores can be either counting or binary - lwIP works with both
|
||||
kinds. Mailboxes are used for message passing and can be implemented
|
||||
either as a queue which allows multiple messages to be posted to a
|
||||
mailbox, or as a rendez-vous point where only one message can be
|
||||
posted at a time. lwIP works with both kinds, but the former type will
|
||||
be more efficient. A message in a mailbox is just a pointer, nothing
|
||||
more.
|
||||
|
||||
Semaphores are represented by the type "sys_sem_t" which is typedef'd
|
||||
in the sys_arch.h file. Mailboxes are equivalently represented by the
|
||||
type "sys_mbox_t". lwIP does not place any restrictions on how
|
||||
sys_sem_t or sys_mbox_t are represented internally.
|
||||
|
||||
The following functions must be implemented by the sys_arch:
|
||||
|
||||
- void sys_init(void)
|
||||
|
||||
Is called to initialize the sys_arch layer.
|
||||
|
||||
- sys_sem_t sys_sem_new(u8_t count)
|
||||
|
||||
Creates and returns a new semaphore. The "count" argument specifies
|
||||
the initial state of the semaphore.
|
||||
|
||||
- void sys_sem_free(sys_sem_t sem)
|
||||
|
||||
Deallocates a semaphore.
|
||||
|
||||
- void sys_sem_signal(sys_sem_t sem)
|
||||
|
||||
Signals a semaphore.
|
||||
|
||||
- u32_t sys_arch_sem_wait(sys_sem_t sem, u32_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 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.
|
||||
|
||||
Notice that lwIP implements a function with a similar name,
|
||||
sys_sem_wait(), that uses the sys_arch_sem_wait() function.
|
||||
|
||||
- sys_mbox_t sys_mbox_new(void)
|
||||
|
||||
Creates an empty mailbox.
|
||||
|
||||
- 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)
|
||||
|
||||
Posts the "msg" to the mailbox.
|
||||
|
||||
- u32_t sys_arch_mbox_fetch(sys_mbox_t mbox, void **msg, u32_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). 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.
|
||||
|
||||
Note that a function with a similar name, sys_mbox_fetch(), is
|
||||
implemented by lwIP.
|
||||
|
||||
- struct sys_timeouts *sys_arch_timeouts(void)
|
||||
|
||||
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(void (* thread)(void *arg), void *arg, int prio)
|
||||
|
||||
Starts a new thread 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 id of the new thread is returned. Both the id and
|
||||
the priority are system dependent.
|
||||
|
||||
- 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.

|
||||
Additional files required for the "OS support" emulation layer:
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
cc.h - Architecture environment, some compiler specific, some
|
||||
environment specific (probably should move env stuff
|
||||
to sys_arch.h.)
|
||||
|
||||
Typedefs for the types used by lwip -
|
||||
u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t
|
||||
|
||||
Compiler hints for packing lwip's structures -
|
||||
PACK_STRUCT_FIELD(x)
|
||||
PACK_STRUCT_STRUCT
|
||||
PACK_STRUCT_BEGIN
|
||||
PACK_STRUCT_END
|
||||
|
||||
Platform specific diagnostic output -
|
||||
LWIP_PLATFORM_DIAG(x) - non-fatal, print a message.
|
||||
LWIP_PLATFORM_ASSERT(x) - fatal, print message and abandon execution.
|
||||
|
||||
"lightweight" synchronization mechanisms -
|
||||
SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable.
|
||||
SYS_ARCH_PROTECT(x) - enter protection mode.
|
||||
SYS_ARCH_UNPROTECT(x) - leave protection mode.
|
||||
|
||||
If the compiler does not provide memset() this file must include a
|
||||
definition of it, or include a file which defines it.
|
||||
|
||||
This file must either include a system-local <errno.h> which defines
|
||||
the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO
|
||||
to make lwip/arch.h define the codes which are used throughout.
|
||||
|
||||
|
||||
perf.h - Architecture specific performance measurement.
|
||||
Measurement calls made throughout lwip, these can be defined to nothing.
|
||||
PERF_START - start measuring something.
|
||||
PERF_STOP(x) - stop measuring something, and record the result.
|
||||
|
||||
sys_arch.h - Tied to sys_arch.c
|
||||
|
||||
Arch dependent types for the following objects:
|
||||
sys_sem_t, sys_mbox_t, sys_thread_t,
|
||||
And, optionally:
|
||||
sys_prot_t
|
||||
|
||||
Defines to set vars of sys_mbox_t and sys_sem_t to NULL.
|
||||
SYS_MBOX_NULL NULL
|
||||
SYS_SEM_NULL NULL

/**

* Packet buffer management
|
||||
*
|
||||
* Packets are built from the pbuf data structure. It supports dynamic
|
||||
* memory allocation for packet contents or can reference externally
|
||||
* managed packet contents both in RAM and ROM. Quick allocation for
|
||||
* incoming packets is provided through pools with fixed sized pbufs.
|
||||
*
|
||||
* A packet may span over multiple pbufs, chained as a singly linked
|
||||
* list. This is called a "pbuf chain".
|
||||
*
|
||||
* Multiple packets may be queued, also using this singly linked list.
|
||||
* This is called a "packet queue".
|
||||
*
|
||||
* So, a packet queue consists of one or more pbuf chains, each of
|
||||
* which consist of one or more pbufs. Currently, queues are only
|
||||
* supported in a limited section of lwIP, this is the etharp queueing
|
||||
* code. Outside of this section no packet queues are supported yet.
|
||||
*
|
||||
* The differences between a pbuf chain and a packet queue are very
|
||||
* precise but subtle.
|
||||
*
|
||||
* The last pbuf of a packet has a ->tot_len field that equals the
|
||||
* ->len field. It can be found by traversing the list. If the last
|
||||
* pbuf of a packet has a ->next field other than NULL, more packets
|
||||
* are on the queue.
|
||||
*
|
||||
* Therefore, looping through a pbuf of a single packet, has an
|
||||
* loop end condition (tot_len == p->len), NOT (next == NULL).

* - PBUF_REF: no buffer memory is allocated for the pbuf, even for
|
||||
* protocol headers. It is assumed that the pbuf is only
|
||||
* being used in a single thread. If the pbuf gets queued,
|
||||
* then pbuf_take should be called to copy the buffer.
|
||||
* - PBUF_POOL: the pbuf is allocated as a pbuf chain, with pbufs from
|
||||
* the pbuf pool that is allocated during pbuf_init().
|
||||
*
|
