Based from pppd 2.4.5, released 2009-11-17, with huge changes to match code size and memory requirements for embedded devices, including: - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which is more or less what pppd sys-* files are, so that we get something working using the unix port. - Merged some patchs from lwIP Git repository which add interesting features or fix bugs. - Merged some patchs from Debian pppd package which add interesting features or fix bugs. - Ported PPP timeout handling to the lwIP timers system - Disabled all the PPP code using filesystem access, replaced in necessary cases to configuration variables. - Disabled all the PPP code forking processes. - Removed IPX support, lwIP does not support IPX. - Ported and improved random module from the previous PPP port. - Removed samba TDB (file-driven database) usage, because it needs a filesystem. - MS-CHAP required a DES implementation, we added the latest PolarSSL DES implementation which is under a BSD-ish license. - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be used in embedded devices with reduced memory footprint. - Removed PPP configuration file parsing support. - Added macro definition EAP_SUPPORT to make EAP support optional. - Added macro definition CHAP_SUPPORT to make CHAP support optional. - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional. - Added macro definition PAP_SUPPORT to make PAP support optional. - Cleared all Linux syscall calls. - Disabled demand support using a macro, so that it can be ported later. - Disabled ECP support using a macro, so that it can be ported later. - Disabled CCP support using a macro, so that it can be ported later. - Disabled CBCP support using a macro, so that it can be ported later. - Disabled LQR support using a macro, so that it can be ported later. - Print packet debug feature optional, through PRINTPKT_SUPPORT - Removed POSIX signal usage. - Fully ported PPPoS code from the previous port. - Fully ported PPPoE code from the previous port. - Fully ported VJ compression protocol code from the previous port. - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF. - Disabled PPP server support using a macro, so that it can be ported later. - Switched all PPP debug to lwIP debug system. - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere, removed all global variables everywhere, did everything necessary for the PPP stack to support more than one PPP session (pppd only support one session per process). - Removed the statically allocated output buffer, now using PBUF. - Improved structure size of all PPP modules, deep analyze of code to reduce variables size to the bare minimum. Switched all boolean type (char type in most architecture) to compiler generated bitfields. - Added PPP IPv6 support, glued lwIP IPv6 support to PPP. - Now using a persistent netif interface which can then be used in lwIP functions requiring a netif. - Now initializing PPP in lwip_init() function. - Reworked completely the PPP state machine, so that we don't end up in anymore in inconsistent state, especially with PPPoE. - Improved the way we handle PPP reconnection after disconnect, cleaning everything required so that we start the PPP connection again from a clean state. - Added PPP holdoff support, allow the lwIP user to wait a little bit before reconnecting, prevents connection flood, especially when using PPPoL2TP. - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client feature to lwIP, L2TP being a widely used tunnel protocol. - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...) - Added PPP API "sequential" thread-safe API, based from NETIFAPI. 2011-07-21: Simon Goldschmidt * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD return the size of the next pending datagram. 2011-05-25: Simon Goldschmidt * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c, combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP code so that the code is more readable. 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt) * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to Ivan! (this is work in progress: we're just post release anyway :-) ++ Bugfixes: 2016-08-23: Simon Goldschmidt * etharp: removed ETHARP_TRUST_IP_MAC since it is insecure and we don't need it any more after implementing unicast ARP renewal towards arp entry timeout 2016-07-20: Simon Goldschmidt * memp.h/.c: fixed bug #48442 (memp stats don't work for MEMP_MEM_MALLOC) 2016-07-21: Simon Goldschmidt (patch by Ambroz Bizjak) * tcp_in.c, tcp_out.c: fixed bug #48543 (TCP sent callback may prematurely report sent data when only part of a segment is acked) and don't include SYN/FIN in snd_buf counter 2016-07-19: Simon Goldschmidt * etharp.c: fixed bug #48477 (ARP input packet might update static entry) 2016-07-11: Simon Goldschmidt * tcp_in.c: fixed bug #48476 (TCP sent callback called wrongly due to picking up old pcb->acked 2016-06-30: Simon Goldschmidt (original patch by Fabian Koch) * tcp_in.c: fixed bug #48170 (Vulnerable to TCP RST spoofing) 2016-05-20: Dirk Ziegelmeier * sntp.h/.c: Fix return value of sntp_getserver() call to return a pointer 2016-04-05: Simon Goldschmidt (patch by Philip Gladstone) * udp.c: patch #8358: allow more combinations of listening PCB for IPv6 2016-04-05: Simon Goldschmidt * netconn/socket API: fixed bug# 43739 (Accept not reporting errors about aborted connections): netconn_accept() returns ERR_ABRT (sockets: ECONNABORTED) for aborted connections, ERR_CLSD (sockets: EINVAL) if the listening netconn is closed, which better seems to follow the standard. 2016-03-23: Florent Matignon * dhcp.c: fixed bug #38203: DHCP options are not recorded in all DHCP ack messages 2016-03-22: Simon Goldschmidt * tcp: changed accept handling to be done internally: the application does not have to call tcp_accepted() any more. Instead, when delaying accept (e.g. sockets do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug #46696) 2016-03-22: Simon Goldschmidt * dns.c: ignore dns response parsing errors, only abort resolving for correct responses or error responses from correct server (bug #47459) 2016-03-17: Simon Goldschmidt * api_msg.c: fixed bug #47448 (netconn/socket leak if RST is received during close) 2016-03-17: Joel Cunningham * api_msg.c: don't fail closing a socket/netconn when failing to allocate the FIN segment; blocking the calling thread for a while is better than risking leaking a

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).  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. 2007-06-21 Simon Goldschmidt * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into int to be able to send a bigger buffer than 64K with one time (mainly used from lwip_send). 2007-06-21 Simon Goldschmidt * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. 2007-06-21 Simon Goldschmidt * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in netconn_write from api_lib.c to api_msg.c to also prevent multiple context- changes on low memory or empty send-buffer. 2007-06-18 Simon Goldschmidt * etharp.c, etharp.h: Changed etharp to use a defined hardware address length of 6 to avoid loading netif->hwaddr_len every time (since this file is only used for ethernet and struct eth_addr already had a defined length of 6). 2007-06-17 Simon Goldschmidt * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets to disable UDP checksum generation on transmit. 2007-06-13 Frédéric Bernon, Simon Goldschmidt * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid pointers or parameters, and let the possibility to redefined it in cc.h. Use this macro to check "conn" parameter in api_msg.c functions. 2007-06-11 Simon Goldschmidt * sockets.c, sockets.h: Added UDP lite support for sockets 2007-06-10 Simon Goldschmidt * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled by default) to switch off UDP-Lite support if not needed (reduces udp.c code size) 2007-06-09 Dominik Spies (integrated by Frédéric Bernon) * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h: AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt (see TODO mark in the source code). 2007-06-09 Simon Goldschmidt * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for etharp_output() to match netif->output so etharp_output() can be used directly as netif->output to save one function call. 2007-06-08 Simon Goldschmidt * netif.h, ethernetif.c, slipif.c, loopif.c: Added define NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables, added initialization of those to ethernetif, slipif and loopif. 2007-05-18 Simon Goldschmidt * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF (defaulting to off for now) that can be set to 0 to send fragmented packets by passing PBUF_REFs down the stack. 2007-05-23 Frédéric Bernon * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP connections, such present in patch #5959. 2007-05-23 Frédéric Bernon * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx code in only one part... 2007-05-18 Simon Goldschmidt * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp elements to overflow. This is achieved by adding some bytes before and after each pool element (increasing their size, of course), filling them with a prominent value and checking them on freeing the element. Set it to 2 to also check every element in every pool each time memp_malloc() or memp_free() is called (slower but more helpful). 2007-05-10 Simon Goldschmidt * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce code size. 2007-05-11 Frédéric Bernon * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: Include a function pointer instead of a table index in the message to reduce footprint. Disable some part of lwip_send and lwip_sendto if some options are not set (LWIP_TCP, LWIP_UDP, LWIP_RAW). 2007-05-10 Simon Goldschmidt * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus \ extern "C" {' in all header files. Now you can write your application using the lwIP stack in C++ and simply #include the core files. Note I have left out the netif/ppp/*h header files for now, since I don't know which files are included by applications and which are for internal use only. 2007-05-09 Simon Goldschmidt * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for situations where some compilers might inline the copy and save a function call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). 2007-05-08 Simon Goldschmidt * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc()) to be overriden in case the C-library malloc implementation is not protected against concurrent access. 2007-05-04 Simon Goldschmidt (Atte Kojo) * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending multiple packets to the same host. 2007-05-04 Frédéric Bernon, Jonathan Larmour * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible to corrupt remote addr/port connection state". Reduce problems "not enought memory" with netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function. Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct, these fields are now renamed "addr" & "port". 2007-04-11 Jonathan Larmour * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro by the port in sys_arch.h if desired. 2007-04-06 Frédéric Bernon, Simon Goldschmidt * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp clients, using new functions from netifapi.h. Disable as default (no port change to do). 2007-04-05 Frédéric Bernon * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant. 2007-04-04 Simon Goldschmidt * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x) use this for and architecture-independent form to tell the compiler you intentionally are not using this variable. Can be overriden in cc.h. 2007-03-28 Frédéric Bernon * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded string, point on one of your's ethernetif field, or alloc a string you will free yourself). It will be used by DHCP to register a client hostname, but can also be use when you call snmp_set_sysname. 2007-03-28 Frédéric Bernon * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to initialize a network interface's flag with. It tell this interface is an ethernet device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility Support for IPv4" section 4.6) when interface is "up" with netif_set_up(). 2007-03-26 Frédéric Bernon, Jonathan Larmour * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build time if you only use PPP or SLIP. The default is enable. Note we don't have to call etharp_init in your port's initilization sequence if you use tcpip.c, because this call is done in tcpip_init function. 2007-03-22 Frédéric Bernon * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in your lwipopts.h. More, unused counters are not defined in the stats structs, and not display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined but never used. Fix msg_in.c with the correct #if test for a stat display. 2007-03-21 Kieran Mansley * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com). Provides callback on netif up/down state change. 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c, ip.c, netif.h, tcpip.c, opt.h: New configuration option LWIP_IGMP to enable IGMP processing. Based on only one filter per all network interfaces. Declare a new function in netif to enable to control the MAC filter (to reduce lwIP traffic processing). 2007-03-11 Frédéric Bernon * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this unless you know what you're doing (default are RFC1122 compliant). Note that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds. 2007-03-08 Frédéric Bernon * tcp.h: Keepalive values can be configured at compile time, but don't change this unless you know what you're doing (default are RFC1122 compliant). 2007-03-08 Frédéric Bernon * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h: Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO on UDP sockets/netconn. 2007-03-08 Simon Goldschmidt * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time. 2007-03-06 Frédéric Bernon * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h: Implement SO_RCVTIMEO on UDP sockets/netconn. 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt) * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated on the stack and remove the API msg type from memp 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) * sockets.h, sockets.c: Move socket initialization to new lwip_socket_init() function. NOTE: this changes the API with ports. Ports will have to be updated to call lwip_socket_init() now. 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) * api_lib.c: Use memcpy in netbuf_copy_partial. ++ Bug fixes: 2008-03-17 Frédéric Bernon, Ed Kerekes * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have some problems to fill the IP header on some targets, use now the ip.h macros to do it). 2008-03-13 Frédéric Bernon * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a TCP connection caused a crash. Note that using (lwip_)recvfrom like this is a bit slow and that using (lwip)getpeername is the good lwip way to do it (so, using recv is faster on tcp sockets). 2008-03-12 Frédéric Bernon, Jonathan Larmour * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's recv_raw() does not consume data", and the ping sample (with LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom returned the IP payload, without the IP header). 2008-03-04 Jonathan Larmour * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors and/or war
