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, IPv4 and IPv6) 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
|
||||
* MLD (Multicast listener discovery for IPv6). Aims to be compliant with
|
||||
RFC 2710. No support for MLDv2
|
||||
* ND (Neighbor discovery and stateless address autoconfiguration for IPv6).
|
||||
Aims to be compliant with RFC 4861 (Neighbor discovery) and RFC 4862
|
||||
(Address autoconfiguration)
|
||||
* UDP (User Datagram Protocol) including experimental UDP-lite extensions
|
||||
* TCP (Transmission Control Protocol) with congestion control, RTT estimation
|
||||
and fast recovery/fast retransmit
|
||||
* raw/native API for enhanced performance
|
||||
* Optional Berkeley-like socket API
|
||||
* DNS (Domain names resolver)
|
||||
|
||||
|
||||
APPLICATIONS
|
||||
|
||||
* HTTP server with SSI and CGI
|
||||
* SNMPv2c agent with MIB compiler (Simple Network Management Protocol)
|
||||
* SNTP (Simple network time protocol)
|
||||
* NetBIOS name service responder
|
||||
* MDNS (Multicast DNS) responder
|
||||
* iPerf server implementation

|
||||
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/
|
||||
|
||||
Continuous integration builds (GCC, clang):
|
||||
https://travis-ci.org/yarrick/lwip-merged
|
||||
|
||||
|
||||
DOCUMENTATION
|
||||
|
||||
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 growing 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/
|
||||
|
||||
lwIP was originally written by Adam Dunkels:
|
||||
http://dunkels.com/adam/
|
||||
|
||||
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.

The major jobs following RT-Thread Team. The RT-Thread network interface device need to synchronize some network status and address information in lwIP, so it need to make some changes in the lwIP netwrok status and address operations function.
|
||||
The specific changes are as follows:
|
||||
|
||||
- netif.c: add RT-Thread netdev header file , status synchronize(UP, LINK_UP), address synchronize(IP, netmask, gateway);
|
||||
|
||||
- dns.c: add RT-Thread header file, dns servers synchronize;
|
||||
|
||||
- sockets.c: custom 'select' function implementation in RT-Thread by the wait queue mode.

Porting lwip 2.0.2 running on RT-Thread.
|
||||
The major jobs following RT-Thread Team. The RT-Thread team already port the lwip 2.0.0, so I only do some move code and test jobs.
|
||||
I use the memory pools to test lwip 2.0.2, I use the iperf tool to test it about more than 20 hours, It is running normal.
|
||||
I don't test it working on memory heap.
|
||||
...
|
||||
Good Luck.

(git master)
|

|
||||
* [Enter new changes just after this line - do not remove this line]
|
||||
|
||||
(2.0.2)
|
||||
|
||||
++ Application changes:
|
||||
|
||||
* slipif: The way to pass serial port number has changed. netif->num is not
|
||||
supported any more, netif->state is interpreted as an u8_t port number now
|
||||
(it's not a POINTER to an u8_t any more!)
|
||||
|
||||
(2.0.1)
|
||||
|
||||
++ Application changes:
|
||||
|
||||
* UDP does NOT receive multicast traffic from ALL netifs on an UDP PCB bound to a specific
|
||||
netif any more. Users need to bind to IP_ADDR_ANY to receive multicast traffic and compare
|
||||
ip_current_netif() to the desired netif for every packet.
|
||||
See bug #49662 for an explanation.
|
||||
|
||||
(2.0.0)
|
||||
|
||||
++ Application changes:
|
||||
|
||||
* Changed netif "up" flag handling to be an administrative flag (as opposed to the previous meaning of
|
||||
"ip4-address-valid", a netif will now not be used for transmission if not up) -> even a DHCP netif
|
||||
has to be set "up" before starting the DHCP client
|
||||
* Added IPv6 support (dual-stack or IPv4/IPv6 only)
|
||||
* Changed ip_addr_t to be a union in dual-stack mode (use ip4_addr_t where referring to IPv4 only).
|
||||
* Major rewrite of SNMP (added MIB parser that creates code stubs for custom MIBs);
|
||||
supports SNMPv2c (experimental v3 support)
|
||||
* Moved some core applications from contrib repository to src/apps (and include/lwip/apps)
|
||||
|
||||
+++ Raw API:
|
||||
* Changed TCP listen backlog: removed tcp_accepted(), added the function pair tcp_backlog_delayed()/
|
||||
tcp_backlog_accepted() to explicitly delay backlog handling on a connection pcb
|
||||
|
||||
+++ Socket API:
|
||||
* Added an implementation for posix sendmsg()
|
||||
* Added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD return the size of the next pending datagram
|
||||
|
||||
++ Port changes
|
||||
|
||||
+++ new files:
|
||||
* MANY new and moved files!
|
||||
* Added src/Filelists.mk for use in Makefile projects
|
||||
* Continued moving stack-internal parts from abc.h to abc_priv.h in sub-folder "priv"
|
||||
to let abc.h only contain the actual application programmer's API
|
||||
|
||||
+++ sys layer:
|
||||
* Made LWIP_TCPIP_CORE_LOCKING==1 the default as it usually performs better than
|
||||
the traditional message passing (although with LWIP_COMPAT_MUTEX you are still
|
||||
open to priority inversion, so this is not recommended any more)
|
||||
* Added LWIP_NETCONN_SEM_PER_THREAD to use one "op_completed" semaphore per thread
|
||||
instead of using one per netconn (these semaphores are used even with core locking
|
||||
enabled as some longer lasting functions like big writes still need to delay)
|
||||
* Added generalized abstraction for itoa(), strnicmp(), stricmp() and strnstr()
|
||||
in def.h (to be overridden in cc.h) instead of config
|
||||
options for netbiosns, httpd, dns, etc. ...
|
||||
* New abstraction for hton* and ntoh* functions in def.h.
|
||||
To override them, use the following in cc.h:
|
||||
#define lwip_htons(x) <your_htons>
|
||||
#define lwip_htonl(x) <your_htonl>
|
||||
|
||||
+++ new options:
|
||||
* TODO
|
||||
|
||||
+++ new pools:
|
||||
* Added LWIP_MEMPOOL_* (declare/init/alloc/free) to declare private memp pools
|
||||
that share memp.c code but do not have to be made global via lwippools.h
|
||||
* Added pools for IPv6, MPU_COMPATIBLE, dns-api, netif-api, etc.
|
||||
* added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when a memp pool was empty and an item
|
||||
is now available
|
||||
|
||||
* Signature of LWIP_HOOK_VLAN_SET macro was changed
|
||||
|
||||
* LWIP_DECLARE_MEMORY_ALIGNED() may be used to declare aligned memory buffers (mem/memp)
|
||||
or to move buffers to dedicated memory using compiler attributes
|
||||
|
||||
* Standard C headers are used to define sized types and printf formatters
|
||||
(disable by setting LWIP_NO_STDINT_H=1 or LWIP_NO_INTTYPES_H=1 if your compiler
|
||||
does not support these)
|
||||
|
||||
|
||||
++ Major bugfixes/improvements
|
||||
|
||||
* Added IPv6 support (dual-stack or IPv4/IPv6 only)
|
||||
* Major rewrite of PPP (incl. keep-up with apache pppd)
|
||||
see doc/ppp.txt for an upgrading how-to
|
||||
* Major rewrite of SNMP (incl. MIB parser)
|
||||
* Fixed timing issues that might have lead to losing a DHCP lease
|
||||
* Made rx processing path more robust against crafted errors
|
||||
* TCP window scaling support
|
||||
* modification of api modules to support FreeRTOS-MPU (don't pass stack-pointers to other threads)
|
||||
* made DNS client more robust
|
||||
* support PBUF_REF for RX packets
|
||||
* LWIP_NETCONN_FULLDUPLEX allows netconn/sockets to be used for reading/writing from separate
|
||||
threads each (needs LWIP_NETCONN_SEM_PER_THREAD)
|
||||
* Moved and reordered stats (mainly memp/mib2)
|
||||
|
||||
(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
|
||||
|
||||
(STABLE-1.3.2)

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 preferred 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.

/**

*
|
||||
* Multiple Execution Contexts in lwIP code
|
||||
* ========================================
|
||||
*
|
||||
* The most common source of lwIP problems is to have multiple execution contexts
|
||||
* inside the lwIP code.
|
||||
*
|
||||
* lwIP can be used in two basic modes: @ref lwip_nosys (no OS/RTOS
|
||||
* running on target system) or @ref lwip_os (there is an OS running
|
||||
* on the target system).
|
||||
*
|
||||
* Mainloop Mode
|
||||
* -------------
|
||||
* In mainloop mode, only @ref callbackstyle_api can be used.
|
||||
* The user has two possibilities to ensure there is only one
|
||||
* exection context at a time in lwIP:
|
||||
*
|
||||
* 1) Deliver RX ethernet packets directly in interrupt context to lwIP
|
||||
* by calling netif->input directly in interrupt. This implies all lwIP
|
||||
* callback functions are called in IRQ context, which may cause further
|
||||
* problems in application code: IRQ is blocked for a long time, multiple
|
||||
* execution contexts in application code etc. When the application wants
|
||||
* to call lwIP, it only needs to disable interrupts during the call.
|
||||
* If timers are involved, even more locking code is needed to lock out
|
||||
* timer IRQ and ethernet IRQ from each other, assuming these may be nested.
|
||||
*
|
||||
* 2) Run lwIP in a mainloop. There is example code here: @ref lwip_nosys.
|
||||
* lwIP is _ONLY_ called from mainloop callstacks here. The ethernet IRQ
|
||||
* has to put received telegrams into a queue which is polled in the
|
||||
* mainloop. Ensure lwIP is _NEVER_ called from an interrupt, e.g.
|
||||
* some SPI IRQ wants to forward data to udp_send() or tcp_write()!
|
||||
*
|
||||
* OS Mode
|
||||
* -------
|
||||
* In OS mode, @ref callbackstyle_api AND @ref sequential_api can be used.
|
||||
* @ref sequential_api are designed to be called from threads other than
|
||||
* the TCPIP thread, so there is nothing to consider here.
|
||||
* But @ref callbackstyle_api functions must _ONLY_ be called from
|
||||
* TCPIP thread. It is a common error to call these from other threads
|
||||
* or from IRQ contexts. Ethernet RX needs to deliver incoming packets
|
||||
* in the correct way by sending a message to TCPIP thread, this is
|
||||
* implemented in tcpip_input().
|
||||
* Again, ensure lwIP is _NEVER_ called from an interrupt, e.g.
|
||||
* some SPI IRQ wants to forward data to udp_send() or tcp_write()!
|
||||
*
|
||||
* 1) tcpip_callback() can be used get called back from TCPIP thread,
|
||||
* it is safe to call any @ref callbackstyle_api from there.
|
||||
*
|
||||
* 2) Use @ref LWIP_TCPIP_CORE_LOCKING. All @ref callbackstyle_api
|
||||
* functions can be called when lwIP core lock is aquired, see
|
||||
* @ref LOCK_TCPIP_CORE() and @ref UNLOCK_TCPIP_CORE().
|
||||
* These macros cannot be used in an interrupt context!
|
||||
* Note the OS must correctly handle priority inversion for this.

Multicast DNS for lwIP
|
||||
|
||||
Author: Erik Ekman
|
||||
|
||||
|
||||
Note! The MDNS responder does not have all features required by the standards.
|
||||
See notes in src/apps/mdns/mdns.c for what is left. It is however usable in normal
|
||||
cases - but watch out if many devices on the same network try to use the same
|
||||
host/service instance names.
|
||||
|
||||
|
||||
How to enable:
|
||||
==============
|
||||
|
||||
MDNS support does not depend on DNS.
|
||||
MDNS supports using IPv4 only, v6 only, or v4+v6.
|
||||
|
||||
To enable MDNS responder, set
|
||||
LWIP_MDNS_RESPONDER = 1
|
||||
in lwipopts.h and add src/apps/mdns/mdns.c to your list of files to build.
|
||||
|
||||
The max number of services supported per netif is defined by MDNS_MAX_SERVICES,
|
||||
default is 1.
|
||||
|
||||
Increase MEMP_NUM_UDP_PCB by 1. MDNS needs one PCB.
|
||||
Increase LWIP_NUM_NETIF_CLIENT_DATA by 1 (MDNS needs one entry on netif).
|
||||
|
||||
MDNS with IPv4 requires LWIP_IGMP = 1, and preferably LWIP_AUTOIP = 1.
|
||||
MDNS with IPv6 requires LWIP_IPV6_MLD = 1, and that a link-local address is
|
||||
generated.
|
||||
|
||||
The MDNS code puts its structs on the stack where suitable to reduce dynamic
|
||||
memory allocation. It may use up to 1kB of stack.
|
||||
|
||||
MDNS needs a strncasecmp() implementation. If you have one, define
|
||||
LWIP_MDNS_STRNCASECMP to it. Otherwise the code will provide an implementation
|
||||
for you.
|
||||
|
||||
|
||||
How to use:
|
||||
===========
|
||||
|
||||
Call mdns_resp_init() during system initialization.
|
||||
This opens UDP sockets on port 5353 for IPv4 and IPv6.
|
||||
|
||||
|
||||
To start responding on a netif, run
|
||||
mdns_resp_add_netif(struct netif *netif, char *hostname, u32_t dns_ttl)
|
||||
|
||||
The hostname will be copied. If this returns successfully, the netif will join
|
||||
the multicast groups and any MDNS/legacy DNS requests sent unicast or multicast
|
||||
to port 5353 will be handled:
|
||||
- <hostname>.local type A, AAAA or ANY returns relevant IP addresses
|
||||
- Reverse lookups (PTR in-addr.arpa, ip6.arpa) of netif addresses
|
||||
returns <hostname>.local
|
||||
Answers will use the supplied TTL (in seconds)
|
||||
MDNS allows UTF-8 names, but it is recommended to stay within ASCII,
|
||||
since the default case-insensitive comparison assumes this.
|
||||
|
||||
It is recommended to call this function after an IPv4 address has been set,
|
||||
since there is currently no check if the v4 address is valid.
|
||||
|
||||
Call mdns_resp_netif_settings_changed() every time the IP address
|
||||
on the netif has changed.
|
||||
|
||||
To stop responding on a netif, run
|
||||
mdns_resp_remove_netif(struct netif *netif)
|
||||
|
||||
|
||||
Adding services:
|
||||
================
|
||||
|
||||
The netif first needs to be registered. Then run
|
||||
mdns_resp_add_service(struct netif *netif, char *name, char *service,
|
||||
u16_t proto, u16_t port, u32_t dns_ttl,
|
||||
service_get_txt_fn_t txt_fn, void *txt_userdata);
|
||||
|
||||
The name and service pointers will be copied. Name refers to the name of the
|
||||
service instance, and service is the type of service, like _http
|
||||
proto can be DNSSD_PROTO_UDP or DNSSD_PROTO_TCP which represent _udp and _tcp.
|
||||
If this call returns successfully, the following queries will be answered:
|
||||
- _services._dns-sd._udp.local type PTR returns <service>.<proto>.local
|
||||
- <service>.<proto>.local type PTR returns <name>.<service>.<proto>.local
|
||||
- <name>.<service>.<proto>.local type SRV returns hostname and port of service
|
||||
- <name>.<service>.<proto>.local type TXT builds text strings by calling txt_fn
|
||||
with the supplied userdata. The callback adds strings to the reply by calling
|
||||
mdns_resp_add_service_txtitem(struct mdns_service *service, char *txt,
|
||||
int txt_len). Example callback method:
|
||||
|
||||
static void srv_txt(struct mdns_service *service, void *txt_userdata)
|
||||
{
|
||||
res = mdns_resp_add_service_txtitem(service, "path=/", 6);
|
||||
LWIP_ERROR("mdns add service txt failed\n", (res == ERR_OK), return);
|
||||
}
|
||||
|
||||
Since a hostname struct is used for TXT storage each single item can be max
|
||||
63 bytes long, and the total max length (including length bytes for each
|
||||
item) is 255 bytes.
|
||||
|
||||
If your device runs a webserver on port 80, an example call might be:
|
||||
|
||||
mdns_resp_add_service(netif, "myweb", "_http"
|
||||
DNSSD_PROTO_TCP, 80, 3600, srv_txt, NULL);
|
||||
|
||||
which will publish myweb._http._tcp.local for any hosts looking for web servers,
|
||||
and point them to <hostname>.local:80
|
||||
|
||||
Relevant information will be sent as additional records to reduce number of
|
||||
requests required from a client.
|
||||
|
||||
Removing services is currently not supported. Services are removed when the
|
||||
netif is removed.

MQTT client for lwIP
|
||||
|
||||
Author: Erik Andersson
|
||||
|
||||
Details of the MQTT protocol can be found at:
|
||||
http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html
|
||||
|
||||
-----------------------------------------------------------------
|
||||
1. Initial steps, reserve memory and make connection to server:
|
||||
|
||||
1.1: Provide storage
|
||||
|
||||
Static allocation:
|
||||
mqtt_client_t static_client;
|
||||
example_do_connect(&static_client);
|
||||
|
||||
Dynamic allocation:
|
||||
mqtt_client_t *client = mqtt_client_new();
|
||||
if(client != NULL) {
|
||||
example_do_connect(&client);
|
||||
}
|
||||
|
||||
1.2: Establish Connection with server
|
||||
|
||||
void example_do_connect(mqtt_client_t *client)
|
||||
{
|
||||
struct mqtt_connect_client_info_t ci;
|
||||
err_t err;
|
||||
|
||||
/* Setup an empty client info structure */
|
||||
memset(&ci, 0, sizeof(ci));
|
||||
|
||||
/* Minimal amount of information required is client identifier, so set it here */
|
||||
ci.client_id = "lwip_test";
|
||||
|
||||
/* Initiate client and connect to server, if this fails immediately an error code is returned
|
||||
otherwise mqtt_connection_cb will be called with connection result after attempting
|
||||
to establish a connection with the server.
|
||||
For now MQTT version 3.1.1 is always used */
|
||||
|
||||
err = mqtt_client_connect(client, ip_addr, MQTT_PORT, mqtt_connection_cb, 0, &ci);
|
||||
|
||||
/* For now just print the result code if something goes wrong
|
||||
if(err != ERR_OK) {
|
||||
printf("mqtt_connect return %d\n", err);
|
||||
}
|
||||
}
|
||||
|
||||
Connection to server can also be probed by calling mqtt_client_is_connected(client)
|
||||
|
||||
-----------------------------------------------------------------
|
||||
2. Implementing the connection status callback
|
||||
|
||||
|
||||
static void mqtt_connection_cb(mqtt_client_t *client, void *arg, mqtt_connection_status_t status)
|
||||
{
|
||||
err_t err;
|
||||
if(status == MQTT_CONNECT_ACCEPTED) {
|
||||
printf("mqtt_connection_cb: Successfully connected\n");
|
||||
|
||||
/* Setup callback for incoming publish requests */
|
||||
mqtt_set_inpub_callback(client, mqtt_incoming_publish_cb, mqtt_incoming_data_cb, arg);
|
||||
|
||||
/* Subscribe to a topic named "subtopic" with QoS level 1, call mqtt_sub_request_cb with result */
|
||||
err = mqtt_subscribe(client, "subtopic", 1, mqtt_sub_request_cb, arg);
|
||||
|
||||
if(err != ERR_OK) {
|
||||
printf("mqtt_subscribe return: %d\n", err);
|
||||
}
|
||||
} else {
|
||||
printf("mqtt_connection_cb: Disconnected, reason: %d\n", status);
|
||||
|
||||
/* Its more nice to be connected, so try to reconnect */
|
||||
example_do_connect(client);
|
||||
}
|
||||
}
|
||||
|
||||
static void mqtt_sub_request_cb(void *arg, err_t result)
|
||||
{
|
||||
/* Just print the result code here for simplicity,
|
||||
normal behaviour would be to take some action if subscribe fails like
|
||||
notifying user, retry subscribe or disconnect from server */
|
||||
printf("Subscribe result: %d\n", result);
|
||||
}
|
||||
|
||||
-----------------------------------------------------------------
|
||||
3. Implementing callbacks for incoming publish and data
|
||||
|
||||
/* The idea is to demultiplex topic and create some reference to be used in data callbacks
|
||||
Example here uses a global variable, better would be to use a member in arg
|
||||
If RAM and CPU budget allows it, the easiest implementation might be to just take a copy of
|
||||
the topic string and use it in mqtt_incoming_data_cb
|
||||
*/
|
||||
static int inpub_id;
|
||||
static void mqtt_incoming_publish_cb(void *arg, const char *topic, u32_t tot_len)
|
||||
{
|
||||
printf("Incoming publish at topic %s with total length %u\n", topic, (unsigned int)tot_len);
|
||||
|
||||
/* Decode topic string into a user defined reference */
|
||||
if(strcmp(topic, "print_payload") == 0) {
|
||||
inpub_id = 0;
|
||||
} else if(topic[0] == 'A') {
|
||||
/* All topics starting with 'A' might be handled at the same way */
|
||||
inpub_id = 1;
|
||||
} else {
|
||||
/* For all other topics */
|
||||
inpub_id = 2;
|
||||
}
|
||||
}
|
||||
|
||||
static void mqtt_incoming_data_cb(void *arg, const u8_t *data, u16_t len, u8_t flags)
|
||||
{
|
||||
printf("Incoming publish payload with length %d, flags %u\n", len, (unsigned int)flags);
|
||||
|
||||
if(flags & MQTT_DATA_FLAG_LAST) {
|
||||
/* Last fragment of payload received (or whole part if payload fits receive buffer
|
||||
See MQTT_VAR_HEADER_BUFFER_LEN) */
|
||||
|
||||
/* Call function or do action depending on reference, in this case inpub_id */
|
||||
if(inpub_id == 0) {
|
||||
/* Don't trust the publisher, check zero termination */
|
||||
if(data[len-1] == 0) {
|
||||
printf("mqtt_incoming_data_cb: %s\n", (const char *)data);
|
||||
}
|
||||
} else if(inpub_id == 1) {
|
||||
/* Call an 'A' function... */
|
||||
} else {
|
||||
printf("mqtt_incoming_data_cb: Ignoring payload...\n");
|
||||
}
|
||||
} else {
|
||||
/* Handle fragmented payload, store in buffer, write to file or whatever */
|
||||
}
|
||||
}
|
||||
|
||||
-----------------------------------------------------------------
|
||||
4. Using outgoing publish
|
||||
|
||||
|
||||
void example_publish(mqtt_client_t *client, void *arg)
|
||||
{
|
||||
const char *pub_payload= "PubSubHubLubJub";
|
||||
err_t err;
|
||||
u8_t qos = 2; /* 0 1 or 2, see MQTT specification */
|
||||
u8_t retain = 0; /* No don't retain such crappy payload... */
|
||||
err = mqtt_publish(client, "pub_topic", pub_payload, strlen(pub_payload), qos, retain, mqtt_pub_request_cb, arg);
|
||||
if(err != ERR_OK) {
|
||||
printf("Publish err: %d\n", err);
|
||||
}
|
||||
}
|
||||
|

/* Called when publish is complete either with sucess or failure */

Raw TCP/IP interface for lwIP
|
||||
|
||||
Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons
|
||||
|
||||
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.
|
||||
|
||||
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.
|
||||
|
||||
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 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).
|
||||
|
||||
|
||||
** 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.
|
||||
|
||||
All 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.
|
||||
|
||||
Do not confuse the lwIP raw API with raw Ethernet or IP sockets.
|
||||
The former is a way of interfacing the lwIP network stack (including
|
||||
TCP and UDP), the later refers to processing raw Ethernet or IP data
|
||||
instead of TCP connections or UDP packets.
|
||||
|
||||
Raw API applications may never block since all packet processing
|
||||
(input and output) as well as timer processing (TCP mainly) is done
|
||||
in a single execution context.
|
||||
|
||||
--- Callbacks
|
||||
|
||||
Program execution is driven by callbacks functions, which are then
|
||||
invoked by the lwIP core when activity related to that application
|
||||
occurs. A particular application may register to be notified via a
|
||||
callback function for events such as incoming data available, outgoing
|
||||
data sent, error notifications, poll timer expiration, connection
|
||||
closed, etc. An application can provide a callback function to perform
|
||||
processing for any or all of these events. 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, ip_addr_t *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.
|
||||
|
||||
- struct tcp_pcb *tcp_listen_with_backlog(struct tcp_pcb *pcb, u8_t backlog)
|
||||
|
||||
Same as tcp_listen, but limits the number of outstanding connections
|
||||
in the listen queue to the value specified by the backlog argument.
|
||||
To use it, your need to set TCP_LISTEN_BACKLOG=1 in your lwipopts.h.
|
||||
|
||||
- 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, ip_addr_t *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 "err"
|
||||
callback function of this pcb (registered with tcp_err, see below)
|
||||
will be called.
|
||||
|
||||
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, const void *dataptr, u16_t len,
|
||||
u8_t apiflags)
|
||||
|
||||
Enqueues the data pointed to by the argument dataptr. The length of
|
||||
the data is passed as the len parameter. The apiflags can be one or more of:
|
||||
- TCP_WRITE_FLAG_COPY: indicates whether the new memory should be allocated
|
||||
for the data to be copied into. If this flag is not given, no new memory
|
||||
should be allocated and the data should only be referenced by pointer. This
|
||||
also means that the memory behind dataptr must not change until the data is
|
||||
ACKed by the remote host
|
||||
- TCP_WRITE_FLAG_MORE: indicates that more data follows. If this is omitted,
|
||||
the PSH flag is set in the last segment created by this call to tcp_write.
|
||||
If this flag is given, the PSH flag is not set.
|
||||
|
||||
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. If
|
||||
there are no errors and the callback function is to return
|
||||
ERR_OK, then it must free the pbuf. Otherwise, it must not
|
||||
free the pbuf so that lwIP core code can store it.
|
||||
|
||||
- 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,
|
||||
err_t (* poll)(void *arg, struct tcp_pcb *tpcb),
|
||||
u8_t interval)
|
||||
|
||||
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.
|
||||
|
||||
ATTENTION: When calling this from one of the TCP callbacks, make
|
||||
sure you always return ERR_ABRT (and never return ERR_ABRT otherwise
|
||||
or you will risk accessing deallocated memory or memory leaks!
|
||||
|
||||
|
||||
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.
|
||||
|
||||
|
||||
--- 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, ip_addr_t *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, ip_addr_t *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,
|
||||
ip_addr_t *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 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_htons(x) <your_htons>
|
||||
#define lwip_htonl(x) <your_htonl>
|
||||
If you #define them to htons() and htonl(), you should
|
||||
#define LWIP_DONT_PROVIDE_BYTEORDER_FUNCTIONS to prevent lwIP from
|
||||
defining hton*/ntoh* compatibility macros.
|
||||
|
||||
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!

||||
|
||||
|
||||
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
|
||||
this via the Administrator News interface.

sys_arch interface for lwIP
|
||||
|
||||
Author: Adam Dunkels
|
||||
Simon Goldschmidt
|
||||
|
||||
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, mailboxes and mutexes 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. Timer scheduling is implemented in lwIP, but can be implemented
|
||||
by the sys_arch port (LWIP_TIMERS_CUSTOM==1).
|
||||
|
||||
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 should be implemented as a queue which allows multiple messages
|
||||
to be posted (implementing as a rendez-vous point where only one message can be
|
||||
posted at a time can have a highly negative impact on performance). 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". Mutexes are represented by the type "sys_mutex_t".
|
||||
lwIP does not place any restrictions on how these types are represented
|
||||
internally.
|
||||
|
||||
Since lwIP 1.4.0, semaphore, mutexes 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)
|
||||
|
||||
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_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 zero, the thread should be
|
||||
blocked until the semaphore is signalled.
|
||||
|
||||
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.
|
||||
|
||||
- int sys_sem_valid(sys_sem_t *sem)
|
||||
|
||||
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.
|
||||
|
||||
- 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.
|
||||
|
||||
- void sys_mutex_new(sys_mutex_t *mutex)
|
||||
|
||||
Creates a new mutex. The mutex is allocated to the memory that 'mutex'
|
||||
points to (which can be both a pointer or the actual OS structure).
|
||||
If the mutex 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_mutex_free(sys_mutex_t *mutex)
|
||||
|
||||
Deallocates a mutex.
|
||||
|
||||
- void sys_mutex_lock(sys_mutex_t *mutex)
|
||||
|
||||
Blocks the thread until the mutex can be grabbed.
|
||||
|
||||
- void sys_mutex_unlock(sys_mutex_t *mutex)
|
||||
|
||||
Releases the mutex previously locked through 'sys_mutex_lock()'.
|
||||
|
||||
- void sys_mutex_valid(sys_mutex_t *mutex)
|
||||
|
||||
Returns 1 if the mutes 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_mutex_set_invalid(sys_mutex_t *mutex)
|
||||
|
||||
Invalidate a mutex so that sys_mutex_valid() returns 0.
|
||||
ATTENTION: This does NOT mean that the mutex shall be deallocated:
|
||||
sys_mutex_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)
|
||||
|
||||
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. This function have to block until
|
||||
the "msg" is really posted.
|
||||
|
||||
- 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)
|
||||
|
||||
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
|
||||
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.
|
||||
|
||||
- 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.
|
||||
|
||||
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)
|
||||
|
||||
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.
|
||||
|
||||
When lwIP is used from more than one context (e.g. from multiple threads OR from
|
||||
main-loop and from interrupts), the SYS_LIGHTWEIGHT_PROT protection SHOULD be enabled!
|
||||
|
||||
- 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 careful 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.

<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.
|
||||
</p>
|
||||
<p>
|
||||
More information about lwIP can be found at the lwIP
|
||||
homepage at <a
|
||||
href="http://savannah.nongnu.org/projects/lwip/">http://savannah.nongnu.org/projects/lwip/</a>

Usage: htmlgen [targetdir] [-s] [-i]s
|
||||
targetdir: relative or absolute path to files to convert
|
||||
switch -s: toggle processing of subdirectories (default is on)
|
||||
switch -e: exclude HTTP header from file (header is created at runtime, default is on)
|
||||
switch -11: include HTTP 1.1 header (1.0 is default)
|
||||
|

if targetdir not specified, makefsdata will attempt to
|
||||
process files in subdirectory 'fs'.
