(CVS HEAD)
(git master)
* [Enter new changes just after this line - do not remove this line]
* TODO
(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

/**
* @page pitfalls Common pitfalls
*
* 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.

Daily Use Guide for using Savannah for lwIP
Table of Contents:
1 - Obtaining lwIP from the Git repository
2 - Committers/developers Git access using SSH
3 - Merging a development branch to master branch
4 - How to release lwIP
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.

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.

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

This directory contains a script ('makefsdata') to create C code suitable for
httpd for given html pages (or other files) in a directory.
There is also a plain C console application doing the same and extended a bit.
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'.
