* New PPP stack for lwIP, developed in ppp-new branch. - 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 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!

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.

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.

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. - - 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 warnings on some systems where mem_size_t and size_t differ. - * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc. - - 2008-03-04 Kieran Mansley (contributions by others) - * Numerous small compiler error/warning fixes from contributions to - mailing list after 1.3.0 release candidate made. - - 2008-01-25 Cui hengbin (integrated by Frédéric Bernon) - * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures. - - 2008-01-15 Kieran Mansley - * tcp_out.c: BUG20511. Modify persist timer to start when we are - prevented from sending by a small send window, not just a zero - send window. - - 2008-01-09 Jonathan Larmour - * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid - conflict with Linux system headers. - - 2008-01-06 Jonathan Larmour - * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP - address entirely on receiving a DHCPNAK, and restarting discovery. - - 2007-12-21 Simon Goldschmidt - * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail - is not protected" by using new macros for interlocked access to modify/test - netconn->recv_avail. - - 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev) - * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state) - - 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm) - * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling - of silly window avoidance and prevent lwIP from shrinking the window) - - 2007-12-04 Simon Goldschmidt - * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last - data packet was lost): add assert that all segment lists are empty in - tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED - state from LAST_ACK in tcp_process - - 2007-12-02 Simon Goldschmidt - * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET - If including for system-struct timeval, LWIP_TIMEVAL_PRIVATE now - has to be set to 0 in lwipopts.h - - 2007-12-02 Simon Goldschmidt - * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always - allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen - netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox. - This is a fix for thread-safety and allocates all items needed for a netconn - when the netconn is created. - - 2007-11-30 Simon Goldschmidt - * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple - netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed - to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same - port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address) - - 2007-11-27 Simon Goldschmidt - * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by - letting ip_route only use netifs that are up. - - 2007-11-27 Simon Goldschmidt - * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF - and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and - sockets block most operations once they have seen a fatal error. - - 2007-11-27 Simon Goldschmidt - * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the - netif to send as an argument (to be able to send on netifs that are down). - - 2007-11-26 Simon Goldschmidt - * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs - arrive out-of-order - - 2007-11-21 Simon Goldschmidt - * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early - Fixed the nagle algorithm; nagle now also works for all raw API applications - and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' - - 2007-11-12 Frédéric Bernon - * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most - of the netconn_peer and netconn_addr processing is done inside tcpip_thread - context in do_getaddr. - - 2007-11-10 Simon Goldschmidt - * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can - happen any time). Now the packet simply isn't enqueued when out of memory. - - 2007-11-01 Simon Goldschmidt - * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or - TCP_MSS if that is smaller) as long as no MSS option is received from the - remote host. - - 2007-11-01 Simon Goldschmidt - * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN) - is now based on TCP_MSS instead of pcb->mss (on passive open now effectively - sending our configured TCP_MSS instead of the one received). - - 2007-11-01 Simon Goldschmidt - * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was - calculated based on the configured TCP_MSS, not on the MSS option received - with SYN+ACK. - - 2007-10-09 Simon Goldschmidt - * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too - short and also was generated wrong if checksum coverage != tot_len; - receive: checksum was calculated wrong if checksum coverage != tot_len - - 2007-10-08 Simon Goldschmidt - * mem.c: lfree was not updated in mem_realloc! - - 2007-10-07 Frédéric Bernon - * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential - crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT: - this change cause an API breakage for netconn_addr, since a parameter - type change. Any compiler should cause an error without any changes in - yours netconn_peer calls (so, it can't be a "silent change"). It also - reduce a little bit the footprint for socket layer (lwip_getpeername & - lwip_getsockname use now a common lwip_getaddrname function since - netconn_peer & netconn_addr have the same parameters). - - 2007-09-20 Simon Goldschmidt - * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) - by checking tcp_tw_pcbs also - - 2007-09-19 Simon Goldschmidt - * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies) - - 2007-09-15 Mike Kleshov - * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used) - - 2007-09-06 Frédéric Bernon - * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove - it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which - already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h" - if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h. - - 2007-08-30 Frédéric Bernon - * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces, - and fix some coding style. - - 2007-08-28 Frédéric Bernon - * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any - kind of packets. These packets are considered like Ethernet packets (payload - pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets - are considered like IP packets (payload pointing to iphdr). - - 2007-08-27 Frédéric Bernon - * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error - problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state - and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT). - - 2007-08-24 Kieran Mansley - * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy - compiler (Paradigm C++) - - 2007-08-09 Frédéric Bernon, Bill Florac - * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement. - Introduce IGMP_STATS to centralize statistics management. - - 2007-08-09 Frédéric Bernon, Bill Florac - * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast - packet on a udp pcb binded on an netif's IP address, and not on "any". - - 2007-08-09 Frédéric Bernon, Bill Florac - * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement. - This is mainly on using lookup/lookfor, and some coding styles... - - 2007-07-26 Frédéric Bernon (and "thedoctor") - * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages. - - 2007-07-25 Simon Goldschmidt - * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if - tcp_output fails in tcp_close, the code in do_close_internal gets simpler - (tcp_output is called again later from tcp timers). - - 2007-07-25 Simon Goldschmidt - * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old - copy_from_pbuf, which illegally modified the given pbuf. - - 2007-07-25 Simon Goldschmidt - * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs: - changed snd_queuelen++ to snd_queuelen += pbuf_clen(p). - - 2007-07-24 Simon Goldschmidt - * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the - correct state (must be CLOSED). - - 2007-07-13 Thomas Taranowski (commited by Jared Grubb) - * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed - allocation. It now returns NULL. - - 2007-07-13 Frédéric Bernon - * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in - all error cases. - - 2007-07-13 Frédéric Bernon - * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed, - because current code doesn't follow rawapi.txt documentation. - - 2007-07-13 Kieran Mansley - * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in - out of sequence processing of received packets - - 2007-07-03 Simon Goldschmidt - * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an - assumption is made that this pbuf is in one piece (i.e. not chained). These - assumptions clash with the possibility of converting to fully pool-based - pbuf implementations, where PBUF_RAM pbufs might be chained. - - 2007-07-03 Simon Goldschmidt - * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems - when closing tcp netconns: removed conn->sem, less context switches when - closing, both netconn_close and netconn_delete should safely close tcp - connections. - - 2007-07-02 Simon Goldschmidt - * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c, - tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off) - to cache ARP table indices with each pcb instead of single-entry cache for - the complete stack. - - 2007-07-02 Simon Goldschmidt - * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent - warnings when assigning to smaller types. - - 2007-06-28 Simon Goldschmidt - * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing. - - 2007-06-28 Simon Goldschmidt - * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if - a segment contained chained pbufs) - - 2007-06-28 Frédéric Bernon - * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute - a "pseudo-random" value based on netif's MAC and some autoip fields. It's always - possible to define this macro in your own lwipopts.h to always use C library's - rand(). Note that autoip_create_rand_addr doesn't use this macro. - - 2007-06-28 Frédéric Bernon - * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option - LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications - in api_lib/api_msg (use pointers and not type with table, etc...) - - 2007-06-26 Simon Goldschmidt - * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines. - - 2007-06-25 Simon Goldschmidt - * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload - for udp packets with no matching pcb. - - 2007-06-25 Simon Goldschmidt - * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match - could get udp input packets if the remote side matched. - - 2007-06-13 Simon Goldschmidt - * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get - changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0. - - 2007-06-13 Simon Goldschmidt - * api_msg.c: pcb_new sets conn->err if protocol is not implemented - -> netconn_new_..() does not allocate a new connection for unsupported - protocols. - - 2007-06-13 Frédéric Bernon, Simon Goldschmidt - * api_lib.c: change return expression in netconn_addr and netconn_peer, because - conn->err was reset to ERR_OK without any reasons (and error was lost)... - - 2007-06-13 Frédéric Bernon, Matthias Weisser - * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename - MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid - some macro names collision with some OS macros. - - 2007-06-11 Simon Goldschmidt - * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0, - create checksum over the complete packet. On RX, if it's < 8 (and not 0), - discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both - UDP & UDP Lite. - - 2007-06-11 Srinivas Gollakota & Oleg Tyshev - * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags" - where TCP flags wasn't initialized in tcp_keepalive. - - 2007-06-03 Simon Goldschmidt - * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function - registered, p->payload was modified without modifying p->len if sending - icmp_dest_unreach() (had no negative effect but was definitively wrong). - - 2007-06-03 Simon Goldschmidt - * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp - re-used the input pbuf even if that didn't have enough space to include the - link headers. Now the space is tested and a new pbuf is allocated for the - echo response packet if the echo request pbuf isn't big enough. - - 2007-06-01 Simon Goldschmidt - * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread. - - 2007-05-23 Frédéric Bernon - * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only - allocated by do_listen if success) and netconn_accept errors handling. In - most of api_lib functions, we replace some errors checkings like "if (conn==NULL)" - by ASSERT, except for netconn_delete. - - 2007-05-23 Frédéric Bernon - * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return - an error code if it's impossible to fetch a pbuf on a TCP connection (and not - directly close the recvmbox). - - 2007-05-22 Simon Goldschmidt - * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of - bound but unconnected (and non-listening) tcp_pcbs. - - 2007-05-22 Frédéric Bernon - * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only - used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of - sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features - like "sys_timeout" in their application threads. - - 2007-05-22 Frédéric Bernon - * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see - which parameters are used by which do_xxx function, and to avoid "misusing" - parameters (patch #5938). - - 2007-05-22 Simon Goldschmidt - * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938: - changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto - is only 8 bits wide. This affects the api, as there, the protocol was - u16_t, too. - - 2007-05-18 Simon Goldschmidt - * memp.c: addition to patch #5913: smaller pointer was returned but - memp_memory was the same size -> did not save memory. - - 2007-05-16 Simon Goldschmidt - * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns - != ERR_OK. - - 2007-05-16 Simon Goldschmidt - * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same - as the one of the netif used for sending to prevent sending from old - addresses after a netif address gets changed (partly fixes bug #3168). - - 2007-05-16 Frédéric Bernon - * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work - with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in - tcpip_init) because we have to be sure that network interfaces are already - added (mac filter is updated only in igmp_init for the moment). - - 2007-05-16 Simon Goldschmidt - * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls - into sys_arch_sem_wait calls to prevent timers from running while waiting - for the heap. This fixes bug #19167. - - 2007-05-13 Simon Goldschmidt - * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines - for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from - tcp.h to sockets.h. - - 2007-05-07 Simon Goldschmidt - * mem.c: Another attempt to fix bug #17922. - - 2007-05-04 Simon Goldschmidt - * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy() - implementation so that it can be reused (don't allocate the target - pbuf inside pbuf_copy()). - - 2007-05-04 Simon Goldschmidt - * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem - to save a little RAM (next pointer of memp is not used while not in pool). - - 2007-05-03 "maq" - * sockets.c: Fix ioctl FIONREAD when some data remains from last recv. - (patch #3574). - - 2007-04-23 Simon Goldschmidt - * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results - in NULL reference for incoming TCP packets". Loopif has to be configured - (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input() - (multithreading environments, e.g. netif->input() = tcpip_input()) or - putting packets on a list that is fed to the stack by calling loopif_poll() - (single-thread / NO_SYS / polling environment where e.g. - netif->input() = ip_input). - - 2007-04-17 Jonathan Larmour - * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold - the difference between two u16_t's. - * sockets.h: FD_SETSIZE needs to match number of sockets, which is - MEMP_NUM_NETCONN in sockets.c right now. - - 2007-04-12 Jonathan Larmour - * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580). - - 2007-04-12 Kieran Mansley - * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission - timer is reset to fix bug#19434, with help from Oleg Tyshev. - - 2007-04-11 Simon Goldschmidt - * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than - previously thought need to be copied (everything but PBUF_ROM!). Cleaned up - pbuf.c: removed functions no needed any more (by etharp). - - 2007-04-11 Kieran Mansley - * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix - "Constant is long" warnings with 16bit compilers. Contributed by - avatar@mmlab.cse.yzu.edu.tw - - 2007-04-05 Frédéric Bernon, Jonathan Larmour - * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on - the mailbox is active". Now, the post is only done during a connect, and do_send, - do_write and do_join_leave_group don't do anything if a previous error was signaled. - - 2007-04-03 Frédéric Bernon - * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output - packets. See patch #5834. - - 2007-03-30 Frédéric Bernon - * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add - missing pcb allocations checking (in do_bind, and for each raw_new). Fix style. - - 2007-03-30 Frédéric Bernon - * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with - others environment defines (these were too "generic"). - - 2007-03-28 Frédéric Bernon - * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call - result and can cause a crash. lwip_send now check netbuf_ref result. - - 2007-03-28 Simon Goldschmidt - * sockets.c Remove "#include " from sockets.c to avoid multiple - definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is - defined. This is the way it should have been already (looking at - doc/sys_arch.txt) - - 2007-03-28 Kieran Mansley - * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS + - IP and TCP headers *and* physical link headers - - 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov) - * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause - to send some garbage. It is not a definitive solution, but the patch does solve - the problem for most cases. - - 2007-03-22 Frédéric Bernon - * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used). - - 2007-03-22 Frédéric Bernon - * api_lib.c: somes resources couldn't be freed if there was errors during - netconn_new_with_proto_and_callback. - - 2007-03-22 Frédéric Bernon - * ethernetif.c: update netif->input calls to check return value. In older ports, - it's a good idea to upgrade them, even if before, there could be another problem - (access to an uninitialized mailbox). - - 2007-03-21 Simon Goldschmidt - * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed - by casting to unsigned). - - 2007-03-21 Frédéric Bernon - * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from - api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a - dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call. - Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a - faster and more reliable communication between api_lib and tcpip. - - 2007-03-21 Frédéric Bernon - * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0. - - 2007-03-21 Frédéric Bernon - * api_msg.c, igmp.c, igmp.h: Fix C++ style comments - - 2007-03-21 Kieran Mansley - * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS + - IP and TCP headers - - 2007-03-21 Kieran Mansley - * Fix all uses of pbuf_header to check the return value. In some - cases just assert if it fails as I'm not sure how to fix them, but - this is no worse than before when they would carry on regardless - of the failure. - - 2007-03-21 Kieran Mansley - * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and - comment out missing header include in icmp.c - - 2007-03-20 Frédéric Bernon - * memp.h, stats.c: Fix stats_display function where memp_names table wasn't - synchronized with memp.h. - - 2007-03-20 Frédéric Bernon - * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input, - tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with - network interfaces.

Should exploit locality. - - 2004-04-29 Leon Woestenberg - * tcp*.c: Cleaned up source comment documentation for Doxygen processing. - * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC. - * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by - the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option. - - ++ Bug fixes: - - 2004-04-27 Leon Woestenberg - * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution - suggested by Timmy Brolin. Fix for 32-bit processors that cannot access - non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix - is to prefix the 14-bit Ethernet headers with two padding bytes. - - 2004-04-23 Leon Woestenberg - * ip_addr.c: Fix in the ip_addr_isbroadcast() check. - * etharp.c: Fixed the case where the packet that initiates the ARP request - is not queued, and gets lost.

Instead, it is a pointer - to a '0.0.0.0' IP address. - - * The packet buffer implementation is changed. The pbuf->ref counter - meaning has changed, and several pbuf functions have been - adapted accordingly. - - * netif drivers have to be changed to set the hardware address length field - that must be initialized correctly by the driver (hint: 6 for Ethernet MAC). - See the contrib/ports/c16x cs8900 driver as a driver example. - - * netif's have a dhcp field that must be initialized to NULL by the driver. - See the contrib/ports/c16x cs8900 driver as a driver example. - -(0.5.x) This file has been unmaintained up to 0.6.1.

All include files are now - kept in a dedicated include/ directory. - - * The API now has proper error handling. A new function, - netconn_err(), now returns an error code for the connection in - case of errors. - - * Improvements in the memory management subsystem. The system now - keeps a pointer to the lowest free memory block. A new function, - mem_malloc2() tries to allocate memory once, and if it fails tries - to free some memory and retry the allocation. - - * Much testing has been done with limited memory - configurations. lwIP now does a better job when overloaded. - - * Some bugfixes and improvements to the buffer (pbuf) subsystem. - - * Many bugfixes in the TCP code: - - - Fixed a bug in tcp_close(). - - - The TCP receive window was incorrectly closed when out of - sequence segments was received.

This has been fixed. - - - Retransmitted segments now contain the correct acknowledgment - number and advertised window. - - - TCP retransmission timeout backoffs are not correctly computed - (ala BSD). After a number of retransmissions, TCP now gives up - the connection. - - * TCP connections now are kept on three lists, one for active - connections, one for listening connections, and one for - connections that are in TIME-WAIT. This greatly speeds up the fast - timeout processing for sending delayed ACKs. - - * TCP now provides proper feedback to the application when a - connection has been successfully set up. - - * More comments have been added to the code. The code has also been - somewhat cleaned up. - -(0.2) Initial public release. diff --git a/third_party/lwip/repo/lwip/COPYING b/third_party/lwip/repo/lwip/COPYING deleted file mode 100644 index e23898b5e8feae..00000000000000 --- a/third_party/lwip/repo/lwip/COPYING +++ /dev/null @@ -1,33 +0,0 @@ -/* - * Copyright (c) 2001, 2002 Swedish Institute of Computer Science. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * - * 1.

If you have a fix put the patch on Savannah. If it is a patch that affects - both core and arch specific stuff please separate them so that the core can - be applied separately while leaving the other patch 'open'. The preferred way - is to NOT touch archs you can't test and let maintainers take care of them. - This is a good way to see if they are used at all - the same goes for unix - netifs except tapif. -4. Do not file a bug and post a fix to it to the patch area. Either a bug report - or a patch will be enough. - If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area. -5. Patches should be specific to a single change or to related changes. Do not mix bugfixes with spelling and other - trivial fixes unless the bugfix is trivial too. Do not reorganize code and rename identifiers in the same patch you - change behaviour if not necessary. A patch is easier to read and understand if it's to the point and short than - if it's not to the point and long :) so the chances for it to be applied are greater. - -2.4 Platform porters: - -1. If you have ported lwIP to a platform (an OS, a uC/processor or a combination of these) and - you think it could benefit others[1] you might want discuss this on the mailing list.

When you change the font size after a successful -# doxygen run you need to manually remove any form_*.png images from the HTML -# output directory to force them to be regenerated. -# Minimum value: 8, maximum value: 50, default value: 10. -# This tag requires that the tag GENERATE_HTML is set to YES. - -FORMULA_FONTSIZE = 10 - -# Use the FORMULA_TRANPARENT tag to determine whether or not the images -# generated for formulas are transparent PNGs. Transparent PNGs are not -# supported properly for IE 6.0, but are supported on all modern browsers. -# -# Note that when changing this option you need to delete any form_*.png files in -# the HTML output directory before the changes have effect. -# The default value is: YES. -# This tag requires that the tag GENERATE_HTML is set to YES. - -FORMULA_TRANSPARENT = YES - -# Enable the USE_MATHJAX option to render LaTeX formulas using MathJax (see -# http://www.mathjax.org) which uses client side Javascript for the rendering -# instead of using pre-rendered bitmaps. Use this if you do not have LaTeX -# installed or if you want to formulas look prettier in the HTML output. When -# enabled you may also need to install MathJax separately and configure the path -# to it using the MATHJAX_RELPATH option. -# The default value is: NO. -# This tag requires that the tag GENERATE_HTML is set to YES. - -USE_MATHJAX = NO - -# When MathJax is enabled you can set the default output format to be used for -# the MathJax output. See the MathJax site (see: -# http://docs.mathjax.org/en/latest/output.html) for more details. -# Possible values are: HTML-CSS (which is slower, but has the best -# compatibility), NativeMML (i.e. MathML) and SVG. -# The default value is: HTML-CSS. -# This tag requires that the tag USE_MATHJAX is set to YES. - -MATHJAX_FORMAT = HTML-CSS - -# When MathJax is enabled you need to specify the location relative to the HTML -# output directory using the MATHJAX_RELPATH option. The destination directory -# should contain the MathJax.js script. For instance, if the mathjax directory -# is located at the same level as the HTML output directory, then -# MATHJAX_RELPATH should be ../mathjax. The default value points to the MathJax -# Content Delivery Network so you can quickly see the result without installing -# MathJax. However, it is strongly recommended to install a local copy of -# MathJax from http://www.mathjax.org before deployment. -# The default value is: http://cdn.mathjax.org/mathjax/latest. -# This tag requires that the tag USE_MATHJAX is set to YES. - -MATHJAX_RELPATH = http://cdn.mathjax.org/mathjax/latest - -# The MATHJAX_EXTENSIONS tag can be used to specify one or more MathJax -# extension names that should be enabled during MathJax rendering. For example -# MATHJAX_EXTENSIONS = TeX/AMSmath TeX/AMSsymbols -# This tag requires that the tag USE_MATHJAX is set to YES. - -MATHJAX_EXTENSIONS = - -# The MATHJAX_CODEFILE tag can be used to specify a file with javascript pieces -# of code that will be used on startup of the MathJax code. See the MathJax site -# (see: http://docs.mathjax.org/en/latest/output.html) for more details. For an -# example see the documentation. -# This tag requires that the tag USE_MATHJAX is set to YES. - -MATHJAX_CODEFILE = - -# When the SEARCHENGINE tag is enabled doxygen will generate a search box for -# the HTML output. The underlying search engine uses javascript and DHTML and -# should work on any modern browser. Note that when using HTML help -# (GENERATE_HTMLHELP), Qt help (GENERATE_QHP), or docsets (GENERATE_DOCSET) -# there is already a search function so this one should typically be disabled. -# For large projects the javascript based search engine can be slow, then -# enabling SERVER_BASED_SEARCH may provide a better solution.
