-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 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 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 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.
-
-** Threading
-
-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"). The raw API may only be used from
-this thread! 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
- - 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.
-
- Only since 1.3.0, 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.
-
-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, 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_accepted(struct tcp_pcb *pcb)
-
- Inform lwIP that an incoming connection has been accepted. This would
- usually be called from the accept callback. This allows lwIP to perform
- housekeeping tasks, such as allowing further incoming connections to be
- queued in the listen backlog.
- ATTENTION: the PCB passed in must be the listening pcb, not the pcb passed
- into the accept callback!
-
-- 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 given,
- 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.
-
-
---- 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, 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 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 ARP_TMR_INTERVAL (5 seconds) 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, ip_addr_t *ipaddr,
- ip_addr_t *netmask, ip_addr_t *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 < 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_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.
-
-
---- Optimalization hints
-
-The first thing you want to optimize is the lwip_standard_checksum()
-routine from src/core/inet.c. You can override this standard
-function with the #define LWIP_CHKSUM <your_checksum_routine>.
-
-There are C examples given in inet.c or you might want to
-craft an assembly function for this. RFC1071 is a good
-introduction to this subject.
-
-Other significant improvements can be made by supplying
-assembly or inline replacements for htons() and htonl()
-if you're using a little-endian architecture.
-#define LWIP_PLATFORM_BYTESWAP 1
-#define LWIP_PLATFORM_HTONS(x) <your_htons>
-#define LWIP_PLATFORM_HTONL(x) <your_htonl>
-
-Check your network interface driver if it reads at
-a higher speed than the maximum wire-speed. If the
-hardware isn't serviced frequently and fast enough
-buffer overflows are likely to occur.
-
-E.g. when using the cs8900 driver, call cs8900if_service(ethif)
-as frequently as possible. When using an RTOS let the cs8900 interrupt
-wake a high priority task that services your driver using a binary
-semaphore or event flag. Some drivers might allow additional tuning
-to match your application and network.
-
-For a production release it is recommended to set LWIP_STATS to 0.
-Note that speed performance isn't influenced much by simply setting
-high values to the memory options.
-
-For more optimization hints take a look at the lwIP wiki.
-
---- Zero-copy MACs
-
-To achieve zero-copy on transmit, the data passed to the raw API must
-remain unchanged until sent. Because the send- (or write-)functions return
-when the packets have been enqueued for sending, data must be kept stable
-after that, too.
-
-This implies that PBUF_RAM/PBUF_POOL pbufs passed to raw-API send functions
-must *not* be reused by the application unless their ref-count is 1.
-
-For no-copy pbufs (PBUF_ROM/PBUF_REF), data must be kept unchanged, too,
-but the stack/driver will/must copy PBUF_REF'ed data when enqueueing, while
-PBUF_ROM-pbufs are just enqueued (as ROM-data is expected to never change).
-
-Also, data passed to tcp_write without the copy-flag must not be changed!
-
-Therefore, be careful which type of PBUF you use and if you copy TCP data
-or not!

-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. \ No newline at end of file

-SNMPv1 agent for lwIP
-
-Author: Christiaan Simons
-
-This is a brief introduction how to use and configure the SNMP agent.
-Note the agent uses the raw-API UDP interface so you may also want to
-read rawapi.txt to gain a better understanding of the SNMP message handling.
-
-0 Agent Capabilities
-====================
-
-SNMPv1 per RFC1157
- This is an old(er) standard but is still widely supported.
- For SNMPv2c and v3 have a greater complexity and need many
- more lines of code. IMHO this breaks the idea of "lightweight IP".
-
- Note the S in SNMP stands for "Simple". Note that "Simple" is
- relative. SNMP is simple compared to the complex ISO network
- management protocols CMIP (Common Management Information Protocol)
- and CMOT (CMip Over Tcp).
-
-MIB II per RFC1213
- The standard lwIP stack management information base.
- This is a required MIB, so this is always enabled.
- When builing lwIP without TCP, the mib-2.tcp group is omitted.
- The groups EGP, CMOT and transmission are disabled by default.
-
- Most mib-2 objects are not writable except:
- sysName, sysLocation, sysContact, snmpEnableAuthenTraps.
- Writing to or changing the ARP and IP address and route
- tables is not possible.
-
- Note lwIP has a very limited notion of IP routing. It currently
- doen't have a route table and doesn't have a notion of the U,G,H flags.
- Instead lwIP uses the interface list with only one default interface
- acting as a single gateway interface (G) for the default route.
-
- The agent returns a "virtual table" with the default route 0.0.0.0
- for the default interface and network routes (no H) for each
- network interface in the netif_list.
- All routes are considered to be up (U).
-
-Loading additional MIBs
- MIBs can only be added in compile-time, not in run-time.
- There is no MIB compiler thus additional MIBs must be hand coded.
-
-Large SNMP message support
- The packet decoding and encoding routines are designed
- to use pbuf-chains. Larger payloads than the minimum
- SNMP requirement of 484 octets are supported if the
- PBUF_POOL_SIZE and IP_REASS_BUFSIZE are set to match your
- local requirement.
-
-1 Building the Agent
-====================
-
-First of all you'll need to add the following define
-to your local lwipopts.h:
-
-#define LWIP_SNMP 1
-
-and add the source files in lwip/src/core/snmp
-and some snmp headers in lwip/src/include/lwip to your makefile.
-
-Note you'll might need to adapt you network driver to update
-the mib2 variables for your interface.
-
-2 Running the Agent
-===================
-
-The following function calls must be made in your program to
-actually get the SNMP agent running.
-
-Before starting the agent you should supply pointers
-to non-volatile memory for sysContact, sysLocation,
-and snmpEnableAuthenTraps. You can do this by calling
-
-snmp_set_syscontact()
-snmp_set_syslocation()
-snmp_set_snmpenableauthentraps()
-
-Additionally you may want to set
-
-snmp_set_sysdescr()
-snmp_set_sysobjid() (if you have a private MIB)
-snmp_set_sysname()
-
-Also before starting the agent you need to setup
-one or more trap destinations using these calls:
-
-snmp_trap_dst_enable();
-snmp_trap_dst_ip_set();
-
-In the lwIP initialisation sequence call snmp_init() just after
-the call to udp_init().
-
-Exactly every 10 msec the SNMP uptime timestamp must be updated with
-snmp_inc_sysuptime(). You should call this from a timer interrupt
-or a timer signal handler depending on your runtime environment.
-
-An alternative way to update the SNMP uptime timestamp is to do a call like
-snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to
-a lower frequency). Another one is to not call snmp_inc_sysuptime() or
-snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
-This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
-snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
-when it's queried (any function which need "sysuptime" have to call
-snmp_get_sysuptime).
-
-
-3 Private MIBs
-==============
-
-If want to extend the agent with your own private MIB you'll need to
-add the following define to your local lwipopts.h:
-
-#define SNMP_PRIVATE_MIB 1
-
-You must provide the private_mib.h and associated files yourself.
-Note we don't have a "MIB compiler" that generates C source from a MIB,
-so you're required to do some serious coding if you enable this!
-
-Note the lwIP enterprise ID (26381) is assigned to the lwIP project,
-ALL OBJECT IDENTIFIERS LIVING UNDER THIS ID ARE ASSIGNED BY THE lwIP
-MAINTAINERS!
-
-If you need to create your own private MIB you'll need
-to apply for your own enterprise ID with IANA: http://www.iana.org/numbers.html
-
-You can set it by passing a struct snmp_obj_id to the agent
-using snmp_set_sysobjid(&my_object_id), just before snmp_init().
-
-Note the object identifiers for thes MIB-2 and your private MIB
-tree must be kept in sorted ascending (lexicographical) order.
-This to ensure correct getnext operation.
-
-An example for a private MIB is part of the "minimal Unix" project:
-contrib/ports/unix/proj/minimal/lwip_prvmib.c
-
-The next chapter gives a more detailed description of the
-MIB-2 tree and the optional private MIB.
-
-4 The Gory Details
-==================
-
-4.0 Object identifiers and the MIB tree.
-
-We have three distinct parts for all object identifiers:
-
-The prefix
- .iso.org.dod.internet
-
-the middle part
- .mgmt.mib-2.ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress
-
-and the index part
- .1.192.168.0.1
-
-Objects located above the .internet hierarchy aren't supported.
-Currently only the .mgmt sub-tree is available and
-when the SNMP_PRIVATE_MIB is enabled the .private tree
-becomes available too.
-
-Object identifiers from incoming requests are checked
-for a matching prefix, middle part and index part
-or are expanded(*) for GetNext requests with short
-or inexisting names in the request.
-(* we call this "expansion" but this also
-resembles the "auto-completion" operation)
-
-The middle part is usually located in ROM (const)
-to preserve precious RAM on small microcontrollers.
-However RAM location is possible for a dynamically
-changing private tree.
-
-The index part is handled by functions which in
-turn use dynamically allocated index trees from RAM.
-These trees are updated by e.g. the etharp code
-when new entries are made or removed form the ARP cache.
-

-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.
-
-Since lwIP 1.4.0, semaphore and mailbox functions are prototyped in a way that
-allows both using pointers or actual OS structures to be used. This way, memory
-required for such types can be either allocated in place (globally or on the
-stack) or on the heap (allocated internally in the "*_new()" functions).
-
-The following functions must be implemented by the sys_arch:
-
-- void sys_init(void)
-
- Is called to initialize the sys_arch layer.
-
-- err_t sys_sem_new(sys_sem_t *sem, u8_t count)
-
- 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.
-
-- 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.
-
-- sys_prot_t sys_arch_protect(void)
-
- This optional function does a "fast" critical region protection and returns
- the previous protection level. This function is only called during very short
- critical regions. An embedded system which supports ISR-based drivers might
- want to implement this function by disabling interrupts. Task-based systems
- might want to implement this by using a mutex or disabling tasking. This
- function should support recursive calls from the same task or interrupt. In
- other words, sys_arch_protect() could be called while already protected. In
- that case the return value indicates that it is already protected.
-
- sys_arch_protect() is only required if your port is supporting an operating
- system.
-
-- void sys_arch_unprotect(sys_prot_t pval)
-
- This optional function does a "fast" set of critical region protection to the
- value specified by pval. See the documentation for sys_arch_protect() for
- more information. This function is only required if your port is supporting
- an operating system.
-
-For some configurations, you also need:
-
-- u32_t sys_now(void)
-
- This optional function returns the current time in milliseconds (don't care
- for wraparound, this is only used for time diffs).
- Not implementing this function means you cannot use some modules (e.g. TCP
- timestamps, internal timeouts for NO_SYS==1).
-
-
-Note:
-
-Be carefull with using mem_malloc() in sys_arch. When malloc() refers to
-mem_malloc() you can run into a circular function call problem. In mem.c
-mem_init() tries to allcate a semaphore using mem_malloc, which of course
-can't be performed when sys_arch uses mem_malloc.
-
--------------------------------------------------------------------------------
-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.
- Portability defines for printf formatters:
- U16_F, S16_F, X16_F, U32_F, S32_F, X32_F, SZT_F
-
- "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
