FUTURE

  * TODO: The lwIP source code makes some invalid assumptions on processor

    word-length, storage sizes and alignment. See the mailing lists for

    problems with exoteric (/DSP) architectures showing these problems.

    We still have to fix some of these issues neatly.

  * TODO: the PPP code is broken in a few ways. There are namespace

    collisions on BSD systems and many assumptions on word-length

    (sizeof(int)). In ppp.c an assumption is made on the availability of

    a thread subsystem. Either PPP needs to be moved to contrib/ports/???

    or rearranged to be more generic.

  2008-03-27 Simon Goldschmidt

  * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free

    from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1

    in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs

    host sent a zero mss as TCP option.

(STABLE-1.3.0)

  ++ New features:

  2008-03-10 Jonathan Larmour

  * inet_chksum.c: Allow choice of one of the sample algorithms to be

    made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.

  2008-01-22 Frédéric Bernon

  * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in

    TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.

  2008-01-14 Frédéric Bernon

  * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable

    to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the

    tcp_recv callback (see rawapi.txt).

  2008-01-14 Frédéric Bernon, Marc Chaland

  * ip.c: Integrate patch #6369" ip_input : checking before realloc".

  2008-01-12 Frédéric Bernon

  * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field

    netconn::sem per netconn::op_completed like suggested for the task #7490

    "Add return value to sys_mbox_post".

  2008-01-12 Frédéric Bernon

  * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,

    DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues

    sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".

  2008-01-10 Frédéric Bernon

  * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490

    "Add return value to sys_mbox_post". tcpip_callback is always defined as

    "blocking" ("block" parameter = 1).

  2008-01-10 Frédéric Bernon

  * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field

    netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490

    "Add return value to sys_mbox_post".

  2008-01-05 Frédéric Bernon

  * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:

    Introduce changes for task #7490 "Add return value to sys_mbox_post" with some

    modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which

    indicate the number of pointers query by the mailbox. There is three defines

    in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the

    netconn::acceptmbox. Port maintainers, you can decide to just add this new

    parameter in your implementation, but to ignore it to keep the previous behavior.

    The new sys_mbox_trypost function return a value to know if the mailbox is

    full or if the message is posted. Take a look to sys_arch.txt for more details.

    This new function is used in tcpip_input (so, can be called in an interrupt

    context since the function is not blocking), and in recv_udp and recv_raw.

  2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour

  * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,

    tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the

    "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add

    documentation in the rawapi.txt file.

  2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)

  * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer

  2007-12-31 Frédéric Bernon, Luca Ceresoli

  * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets

    in autoip". The change in etharp_raw could be removed, since all calls to

    etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be

    wrong in the future.

  2007-12-30 Frédéric Bernon, Tom Evans

  * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address

    Filtering" reported by Tom Evans.

  2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour

  * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,

    sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API

    applications have to call 'tcp_accepted(pcb)' in their accept callback to

    keep accepting new connections.

  2007-12-13 Frédéric Bernon

  * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"

    by err_t type. Add a new err_t code "ERR_INPROGRESS".

  2007-12-12 Frédéric Bernon

  * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles

    are the one which have ram usage.

  2007-12-05 Frédéric Bernon

  * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static

    set of variables (=0) or a local one (=1). In this last case, your port should

    provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"

    which have to do a copy of "h" and return a pointer ont the "per-thread" copy.

  2007-12-03 Simon Goldschmidt

  * ip.c: ip_input: check if a packet is for inp first before checking all other

    netifs on netif_list (speeds up packet receiving in most cases)

  2007-11-30 Simon Goldschmidt

  * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access

    UDP: move a (connected) pcb selected for input to the front of the list of

    pcbs so that it is found faster next time. Same for RAW pcbs that have eaten

    a packet.

  2007-11-28 Simon Goldschmidt

  * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS

  2007-11-25 Simon Goldschmidt

  * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy

    algorithm.

  2007-11-24 Simon Goldschmidt

  * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c

    to the new file netdb.c; included lwip_getaddrinfo.

  2007-11-21 Simon Goldschmidt

  * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss

    based on the MTU of the netif used to send. Enabled by default. Disable by

    setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.

  2007-11-19 Frédéric Bernon

  * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name

    received match the name query), implement DNS_USES_STATIC_BUF (the place where

    copy dns payload to parse the response), return an error if there is no place

    for a new query, and fix some minor problems.

  2007-11-16 Simon Goldschmidt

  * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c

    removed files: core/inet.c, core/inet6.c

    Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into

    inet and chksum part; changed includes in all lwIP files as appropriate

  2007-11-16 Simon Goldschmidt

  * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential

    dns resolver function for netconn api (netconn_gethostbyname) and socket api

    (gethostbyname/gethostbyname_r).

  2007-11-15 Jim Pettinato, Frédéric Bernon

  * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name

    requests with RAW api interface. Initialization is done in lwip_init() with

    build time options. DNS timer is added in tcpip_thread context. DHCP can set

    DNS server ip addresses when options are received. You need to set LWIP_DNS=1

    in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get

    some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"

    list with points to improve.

  2007-11-06 Simon Goldschmidt

  * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly

    enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status

    for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.

  2007-11-06 Simon Goldschmidt

  * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include

    core header files in api.h (ip/tcp/udp/raw.h) to hide the internal

    implementation from netconn api applications.

  2007-11-03 Frédéric Bernon

  * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &

    RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled

    by default). Netconn API users can use the netconn_recv_bufsize macro to access

    it. This is a first release which have to be improve for TCP. Note it used the

    netconn::recv_avail which need to be more "thread-safe" (note there is already

    the problem for FIONREAD with lwip_ioctl/ioctlsocket).

  2007-11-01 Frédéric Bernon, Marc Chaland

  * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:

    Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api

    layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api

    layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.

    Note that previous "copy" parameter for "write" APIs is now called "apiflags".

  2007-10-24 Frédéric Bernon

  * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than

    TCP_EVENT_xxx macros to get a code more readable. It could also help to remove

    some code (like we have talk in "patch #5919 : Create compile switch to remove

    select code"), but it could be done later.

  2007-10-08 Simon Goldschmidt

  * many files: Changed initialization: many init functions are not needed any

    more since we now rely on the compiler initializing global and static

    variables to zero!

  2007-10-06 Simon Goldschmidt

  * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY

    to enqueue the received pbufs so that multiple packets can be reassembled

    simultaneously and no static reassembly buffer is needed.

  2007-10-05 Simon Goldschmidt

  * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so

    all netifs (or ports) can use it.

  2007-10-05 Frédéric Bernon

  * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the

    common function to reduce a little bit the footprint (for all functions using

    only the "netif" parameter).

  2007-10-03 Frédéric Bernon

  * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,

    netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce

    a little bit the footprint (for all functions using only the "netif" parameter).

  2007-09-15 Frédéric Bernon

  * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF

    option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for

    netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for

    IP_MULTICAST_TTL and IP_MULTICAST_IF.

  2007-09-10 Frédéric Bernon

  * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles

    even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()

    each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can

    decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but

    call to a lower frequency). Or, you can decide 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 direct call to "sysuptime" is changed by a call to

    snmp_get_sysuptime).

  2007-09-09 Frédéric Bernon, Bill Florac

  * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,

    and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags

    if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().

    igmp_report_groups() is now called inside netif_set_link_up() (need to have

    LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait

    the next query message to receive the matching multicast streams).

  2007-09-08 Frédéric Bernon

  * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains

    IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).

    Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).

    Enable to access to these fields with LWIP_TCP=0.

  2007-09-05 Frédéric Bernon

  * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,

    ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option

    LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).

    Be careful, disabling ICMP make your product non-compliant to RFC1122, but

    help to reduce footprint, and to reduce "visibility" on the Internet.

  2007-09-05 Frédéric Bernon, Bill Florac

  * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list

    for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new

    parameters have to be provided: a task name, and a task stack size. For this

    one, since it's platform dependant, you could define the best one for you in

    your lwipopts.h. For port maintainers, you can just add these new parameters

    in your sys_arch.c file, and but it's not mandatory, use them in your OS

    specific functions.

  2007-09-05 Frédéric Bernon

  * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings

    inside init.c for task #7142 "Sanity check user-configurable values".

  2007-09-04 Frédéric Bernon, Bill Florac

  * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by

    memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the

    value). It will avoid potential fragmentation problems, use a counter to know

    how many times a group is used on an netif, and free it when all applications

    leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity

    check if LWIP_IGMP!=0).

  2007-09-03 Frédéric Bernon

  * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".

    Initialize igmp_mac_filter to NULL in netif_add (this field should be set in

    the netif's "init" function). Use the "imr_interface" field (for socket layer)

    and/or the "interface" field (for netconn layer), for join/leave operations.

    The igmp_join/leavegroup first parameter change from a netif to an ipaddr.

    This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).

  2007-08-30 Frédéric Bernon

  * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions

    from api/api_lib". Now netbuf API is independant of netconn, and can be used

    with other API (application based on raw API, or future "socket2" API). Ports

    maintainers just have to add src/api/netbuf.c in their makefile/projects.

  2007-08-30 Frédéric Bernon, Jonathan Larmour

  * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check

    user-configurable values".

  2007-08-29 Frédéric Bernon

  * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.

    igmp_start is call inside netif_add. Now, igmp initialization is in the same

    spirit than the others modules. Modify some IGMP debug traces.

  2007-08-29 Frédéric Bernon

  * Add init.h, init.c, Change opt.h, tcpip.c: Task  #7213 "Add a lwip_init function"

    Add lwip_init function to regroup all modules initializations, and to provide

    a place to add code for task #7142 "Sanity check user-configurable values".

    Ports maintainers should remove direct initializations calls from their code,

    and add init.c in their makefiles. Note that lwip_init() function is called

    inside tcpip_init, but can also be used by raw api users since all calls are

    disabled when matching options are disabled. Also note that their is new options

    in opt.h, you should configure in your lwipopts.h (they are enabled per default).

  2007-08-26 Marc Boucher

  * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL

    since they can under certain circumstances be called with an invalid conn

    pointer after the connection has been closed (and conn has been freed).

  2007-08-25 Frédéric Bernon (Artem Migaev's Patch)

  * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".

    Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.

  2007-08-22 Frédéric Bernon

  * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK

    to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.

  2007-08-22 Frédéric Bernon

  * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &

    ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the

    name is tcpip_input (we keep the name of 1.2.0 function).

  2007-08-17 Jared Grubb

  * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool

    settings into new memp_std.h and optional user file lwippools.h. This adds

    more dynamic mempools, and allows the user to create an arbitrary number of

    mempools for mem_malloc.

  2007-08-16 Marc Boucher

  * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;

    otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely

    close the connection.

  2007-08-16 Marc Boucher

  * sockets.c: lwip_accept(): check netconn_peer() error return.

  2007-08-16 Marc Boucher

  * mem.c, mem.h: Added mem_calloc().

  2007-08-16 Marc Boucher

  * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)

    for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG

    and starving other message types.

    Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API

  2007-08-16 Marc Boucher

  * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf

    type and flgs (later renamed to flags).

    Use enum pbuf_flag as pbuf_type.  Renumber PBUF_FLAG_*.

    Improved lwip_recvfrom().  TCP push now propagated.

  2007-08-16 Marc Boucher

  * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global

    provided by etharp.

  2007-08-16 Marc Boucher

  * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,

    etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:

    Added PPPoE support and various PPP improvements.

  2007-07-25 Simon Goldschmidt

  * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,

    making netbuf_copy_partial use this function.

  2007-07-25 Simon Goldschmidt

  * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with

    2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and

    other stacks.

  2007-07-13 Jared Grubb (integrated by Frédéric Bernon)

  * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add

    a link callback in the netif struct, and functions to handle it. Be carefull

    for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)

    if you want to be sure to be compatible with future changes...

  2007-06-30 Frédéric Bernon

  * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.

  2007-06-21 Simon Goldschmidt

  * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both

    LWIP_AUTOIP =0 and =1 to remove redundant code.

  2007-06-21 Simon Goldschmidt

  * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option

    MEM_USE_POOLS to use 4 pools with different sized elements instead of a

    heap. This both prevents memory fragmentation and gives a higher speed

    at the cost of more memory consumption. Turned off by default.
