elessair 0:f269e3021894 8
elessair 0:f269e3021894 9 2016-07-27: Simon Goldschmidt
elessair 0:f269e3021894 10 * opt.h, timeouts.h/.c: added LWIP_TIMERS_CUSTOM to override the default
elessair 0:f269e3021894 11 implementation of timeouts
elessair 0:f269e3021894 12
elessair 0:f269e3021894 13 2016-07-xx: Dirk Ziegelmeier
elessair 0:f269e3021894 14 * Large overhaul of doxygen documentation
elessair 0:f269e3021894 15
elessair 0:f269e3021894 16 2016-04-05: Simon Goldschmidt
elessair 0:f269e3021894 17 * timers.h/.c: prepare for overriding current timeout implementation: all
elessair 0:f269e3021894 18 stack-internal caclic timers are avaliable in the lwip_cyclic_timers array
elessair 0:f269e3021894 19
elessair 0:f269e3021894 20 2016-03-23: Simon Goldschmidt
elessair 0:f269e3021894 21 * tcp: call accept-callback with ERR_MEM when allocating a pcb fails on
elessair 0:f269e3021894 22 passive open to inform the application about this error
elessair 0:f269e3021894 23 ATTENTION: applications have to handle NULL pcb in accept callback!
elessair 0:f269e3021894 24
elessair 0:f269e3021894 25 2016-02-22: Ivan Delamer
elessair 0:f269e3021894 26 * Initial 6LoWPAN support
elessair 0:f269e3021894 27
elessair 0:f269e3021894 28 2016-02-XX to 2016-03-XX: Dirk Ziegelmeier
elessair 0:f269e3021894 29 * Cleanup TCPIP thread sync methods in a way that it is possibe to use them
elessair 0:f269e3021894 30 in arbitrary code that needs things to be done in TCPIP thread. Used to
elessair 0:f269e3021894 31 decouple netconn, netif, ppp and 6LoWPAN from LWIP core.
elessair 0:f269e3021894 32
elessair 0:f269e3021894 33 2016-02-XX: Dirk Ziegelmeier
elessair 0:f269e3021894 34 * Implement dual-stack support in RAW, UDP and TCP. Add new IP address
elessair 0:f269e3021894 35 type IPADDR_ANY_TYPE for this. Netconn/Socket API: Dual-stack is
elessair 0:f269e3021894 36 automatically supported when an IPv6 netconn/socket is created.
elessair 0:f269e3021894 37
elessair 0:f269e3021894 38 2015-12-26: Martin Hentschel and Dirk Ziegelmeier

elessair 0:f269e3021894 40
elessair 0:f269e3021894 41 2015-11-12: Dirk Ziegelmeier
elessair 0:f269e3021894 42 * Decouple SNMP stack from lwIP core and move stack to apps/ directory.
elessair 0:f269e3021894 43 Breaking change: Users have to call snmp_init() now!
elessair 0:f269e3021894 44
elessair 0:f269e3021894 45 2015-11-12: Dirk Ziegelmeier
elessair 0:f269e3021894 46 * Implement possibility to declare private memory pools. This is useful to
elessair 0:f269e3021894 47 decouple some apps from the core (SNMP stack) or make contrib app usage
elessair 0:f269e3021894 48 simpler (httpserver_raw)
elessair 0:f269e3021894 49
elessair 0:f269e3021894 50 2015-10-09: Simon Goldschmidt
elessair 0:f269e3021894 51 * started to move "private" header files containing implementation details to
elessair 0:f269e3021894 52 "lwip/priv/" include directory to seperate the API from the implementation.
elessair 0:f269e3021894 53
elessair 0:f269e3021894 54 2015-10-07: Simon Goldschmidt
elessair 0:f269e3021894 55 * added sntp client as first "supported" application layer protocol implementation
elessair 0:f269e3021894 56 added 'apps' folder
elessair 0:f269e3021894 57
elessair 0:f269e3021894 58 2015-09-30: Dirk Ziegelmeier
elessair 0:f269e3021894 59 * snmp_structs.h, mib_structs.c, mib2.c: snmp: fixed ugly inheritance
elessair 0:f269e3021894 60 implementation by aggregating the "base class" (struct mib_node) in all
elessair 0:f269e3021894 61 derived node classes to get more type-safe code
elessair 0:f269e3021894 62
elessair 0:f269e3021894 63 2015-09-23: Simon Goldschmidt
elessair 0:f269e3021894 64 * netif.h/.c, nd6.c: task #13729: Convert netif addresses (IPv4 & IPv6) to
elessair 0:f269e3021894 65 ip_addr_t (so they can be used without conversion/temporary storage)
elessair 0:f269e3021894 66
elessair 0:f269e3021894 67 2015-09-08: Dirk Ziegelmeier
elessair 0:f269e3021894 68 * snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans
elessair 0:f269e3021894 69 up the code and should allow integration of a 3rd party agent/mib2. Simple
elessair 0:f269e3021894 70 counters are kept in MIB2_STATS, tree/table change function prototypes moved to
elessair 0:f269e3021894 71 snmp_mib2.h.
elessair 0:f269e3021894 72
elessair 0:f269e3021894 73 2015-09-03: Simon Goldschmidt
elessair 0:f269e3021894 74 * opt.h, dns.h/.c: DNS/IPv6: added support for AAAA records

elessair 0:f269e3021894 79
elessair 0:f269e3021894 80 2015-08-30: Simon Goldschmidt
elessair 0:f269e3021894 81 * PBUF_REF with "custom" pbufs is now supported for RX pbufs (see pcapif in
elessair 0:f269e3021894 82 contrib for an example, LWIP_SUPPORT_CUSTOM_PBUF is required)
elessair 0:f269e3021894 83
elessair 0:f269e3021894 84 2015-08-30: Simon Goldschmidt
elessair 0:f269e3021894 85 * support IPv4 source based routing: define LWIP_HOOK_IP4_ROUTE_SRC to point
elessair 0:f269e3021894 86 to a routing function
elessair 0:f269e3021894 87
elessair 0:f269e3021894 88 2015-08-05: Simon Goldschmidt
elessair 0:f269e3021894 89 * many files: allow multicast socket options IP_MULTICAST_TTL, IP_MULTICAST_IF
elessair 0:f269e3021894 90 and IP_MULTICAST_LOOP to be used without IGMP
elessair 0:f269e3021894 91
elessair 0:f269e3021894 92 2015-04-24: Simon Goldschmidt
elessair 0:f269e3021894 93 * dhcp.h/c, autoip.h/.c: added functions dhcp/autoip_supplied_address() to
elessair 0:f269e3021894 94 check for the source of address assignment (replacement for NETIF_FLAG_DHCP)
elessair 0:f269e3021894 95
elessair 0:f269e3021894 96 2015-04-10: Simon Goldschmidt
elessair 0:f269e3021894 97 * many files: task #13480: added LWIP_IPV4 define - IPv4 can be disabled,
elessair 0:f269e3021894 98 leaving an IPv6-only stack
elessair 0:f269e3021894 99
elessair 0:f269e3021894 100 2015-04-09: Simon Goldschmidt
elessair 0:f269e3021894 101 * nearly all files: task #12722 (improve IPv4/v6 address handling): renamed
elessair 0:f269e3021894 102 ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP
elessair 0:f269e3021894 103 version; ip_addr_t is used for all generic IP addresses for the API,
elessair 0:f269e3021894 104 ip(4/6)_addr_t are only used internally or when initializing netifs or when
elessair 0:f269e3021894 105 calling version-related functions
elessair 0:f269e3021894 106
elessair 0:f269e3021894 107 2015-03-24: Simon Goldschmidt
elessair 0:f269e3021894 108 * opt.h, ip4_addr.h, ip4.c, ip6.c: loopif is not required for loopback traffic
elessair 0:f269e3021894 109 any more but passed through any netif (ENABLE_LOOPBACK has to be enabled)
elessair 0:f269e3021894 110
elessair 0:f269e3021894 111 2015-03-23: Simon Goldschmidt

elessair 0:f269e3021894 113 addresses on multiple netifs should now be working correctly (if correctly
elessair 0:f269e3021894 114 addressed by routing, that is)
elessair 0:f269e3021894 115
elessair 0:f269e3021894 116 2015-03-23: Simon Goldschmidt
elessair 0:f269e3021894 117 * etharp.c: Stable etharp entries that are about to expire are now refreshed
elessair 0:f269e3021894 118 using unicast to prevent unnecessary broadcast. Only if no answer is received
elessair 0:f269e3021894 119 after 15 seconds, broadcast is used.
elessair 0:f269e3021894 120
elessair 0:f269e3021894 121 2015-03-06: Philip Gladstone

elessair 0:f269e3021894 123 an interface)
elessair 0:f269e3021894 124
elessair 0:f269e3021894 125 2015-03-05: Simon Goldschmidt
elessair 0:f269e3021894 126 * netif.c, ip4.c, dhcp.c, autoip.c: fixed bug #37068 (netif up/down handling
elessair 0:f269e3021894 127 is unclear): correclty separated administrative status of a netif (up/down)
elessair 0:f269e3021894 128 from 'valid address' status
elessair 0:f269e3021894 129 ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip
elessair 0:f269e3021894 130 is used!
elessair 0:f269e3021894 131
elessair 0:f269e3021894 132 2015-02-26: patch by TabascoEye

elessair 0:f269e3021894 135 2015-02-22: chrysn, Simon Goldschmidt
elessair 0:f269e3021894 136 * *.*: Changed nearly all functions taking 'ip(X)_addr_t' pointer to take
elessair 0:f269e3021894 137 const pointers (changed user callbacks: raw_recv_fn, udp_recv_fn; changed
elessair 0:f269e3021894 138 port callbacks: netif_output_fn, netif_igmp_mac_filter_fn)
elessair 0:f269e3021894 139
elessair 0:f269e3021894 140 2015-02-19: Ivan Delamer
elessair 0:f269e3021894 141 * netif.h, dhcp.c: Removed unused netif flag for DHCP. The preferred way to evaluate
elessair 0:f269e3021894 142 if DHCP is active is through netif->dhcp field.
elessair 0:f269e3021894 143
elessair 0:f269e3021894 144 2015-02-19: Ivan Delamer

elessair 0:f269e3021894 150
elessair 0:f269e3021894 151 2015-02-18: Simon Goldschmidt
elessair 0:f269e3021894 152 * tcp.c: tcp_alloc() prefers killing CLOSING/LAST_ACK over active connections
elessair 0:f269e3021894 153 (see bug #39565)
elessair 0:f269e3021894 154

elessair 0:f269e3021894 185 2015-01-17: Simon Goldschmidt
elessair 0:f269e3021894 186 * api: allow enabling socket API without (public) netconn API - netconn API is
elessair 0:f269e3021894 187 still used by sockets, but keeping it private (static) should allow better
elessair 0:f269e3021894 188 compiler optimizations
elessair 0:f269e3021894 189
elessair 0:f269e3021894 190 2015-01-16: Simon Goldschmidt

elessair 0:f269e3021894 194 2014-12-10: Simon Goldschmidt
elessair 0:f269e3021894 195 * api: added option LWIP_NETCONN_SEM_PER_THREAD to use a semaphore per thread
elessair 0:f269e3021894 196 instead of using one per netconn and per select call
elessair 0:f269e3021894 197
elessair 0:f269e3021894 198 2014-12-08: Simon Goldschmidt

elessair 0:f269e3021894 209
elessair 0:f269e3021894 210 2014-09-16: Simon Goldschmidt
elessair 0:f269e3021894 211 * dns.c, opt.h: reduced ram usage by parsing DNS responses in place
elessair 0:f269e3021894 212
elessair 0:f269e3021894 213 2014-09-16: Simon Goldschmidt

elessair 0:f269e3021894 250 * New PPP stack for lwIP, developed in ppp-new branch.
elessair 0:f269e3021894 251 Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
elessair 0:f269e3021894 252 code size and memory requirements for embedded devices, including:
elessair 0:f269e3021894 253 - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
elessair 0:f269e3021894 254 is more or less what pppd sys-* files are, so that we get something working
elessair 0:f269e3021894 255 using the unix port.
elessair 0:f269e3021894 256 - Merged some patchs from lwIP Git repository which add interesting features
elessair 0:f269e3021894 257 or fix bugs.
elessair 0:f269e3021894 258 - Merged some patchs from Debian pppd package which add interesting features
elessair 0:f269e3021894 259 or fix bugs.
elessair 0:f269e3021894 260 - Ported PPP timeout handling to the lwIP timers system
elessair 0:f269e3021894 261 - Disabled all the PPP code using filesystem access, replaced in necessary cases
elessair 0:f269e3021894 262 to configuration variables.
elessair 0:f269e3021894 263 - Disabled all the PPP code forking processes.
elessair 0:f269e3021894 264 - Removed IPX support, lwIP does not support IPX.
elessair 0:f269e3021894 265 - Ported and improved random module from the previous PPP port.
elessair 0:f269e3021894 266 - Removed samba TDB (file-driven database) usage, because it needs a filesystem.
elessair 0:f269e3021894 267 - MS-CHAP required a DES implementation, we added the latest PolarSSL DES
elessair 0:f269e3021894 268 implementation which is under a BSD-ish license.
elessair 0:f269e3021894 269 - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
elessair 0:f269e3021894 270 used in embedded devices with reduced memory footprint.
elessair 0:f269e3021894 271 - Removed PPP configuration file parsing support.
elessair 0:f269e3021894 272 - Added macro definition EAP_SUPPORT to make EAP support optional.
elessair 0:f269e3021894 273 - Added macro definition CHAP_SUPPORT to make CHAP support optional.
elessair 0:f269e3021894 274 - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.
elessair 0:f269e3021894 275 - Added macro definition PAP_SUPPORT to make PAP support optional.
elessair 0:f269e3021894 276 - Cleared all Linux syscall calls.
elessair 0:f269e3021894 277 - Disabled demand support using a macro, so that it can be ported later.
elessair 0:f269e3021894 278 - Disabled ECP support using a macro, so that it can be ported later.
elessair 0:f269e3021894 279 - Disabled CCP support using a macro, so that it can be ported later.
elessair 0:f269e3021894 280 - Disabled CBCP support using a macro, so that it can be ported later.
elessair 0:f269e3021894 281 - Disabled LQR support using a macro, so that it can be ported later.
elessair 0:f269e3021894 282 - Print packet debug feature optional, through PRINTPKT_SUPPORT
elessair 0:f269e3021894 283 - Removed POSIX signal usage.
elessair 0:f269e3021894 284 - Fully ported PPPoS code from the previous port.
elessair 0:f269e3021894 285 - Fully ported PPPoE code from the previous port.
elessair 0:f269e3021894 286 - Fully ported VJ compression protocol code from the previous port.
elessair 0:f269e3021894 287 - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
elessair 0:f269e3021894 288 - Disabled PPP server support using a macro, so that it can be ported later.
elessair 0:f269e3021894 289 - Switched all PPP debug to lwIP debug system.
elessair 0:f269e3021894 290 - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
elessair 0:f269e3021894 291 removed all global variables everywhere, did everything necessary for
elessair 0:f269e3021894 292 the PPP stack to support more than one PPP session (pppd only support
elessair 0:f269e3021894 293 one session per process).
elessair 0:f269e3021894 294 - Removed the statically allocated output buffer, now using PBUF.
elessair 0:f269e3021894 295 - Improved structure size of all PPP modules, deep analyze of code to reduce
elessair 0:f269e3021894 296 variables size to the bare minimum. Switched all boolean type (char type in
elessair 0:f269e3021894 297 most architecture) to compiler generated bitfields.
elessair 0:f269e3021894 298 - Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
elessair 0:f269e3021894 299 - Now using a persistent netif interface which can then be used in lwIP
elessair 0:f269e3021894 300 functions requiring a netif.
elessair 0:f269e3021894 301 - Now initializing PPP in lwip_init() function.
elessair 0:f269e3021894 302 - Reworked completely the PPP state machine, so that we don't end up in
elessair 0:f269e3021894 303 anymore in inconsistent state, especially with PPPoE.
elessair 0:f269e3021894 304 - Improved the way we handle PPP reconnection after disconnect, cleaning
elessair 0:f269e3021894 305 everything required so that we start the PPP connection again from a
elessair 0:f269e3021894 306 clean state.
elessair 0:f269e3021894 307 - Added PPP holdoff support, allow the lwIP user to wait a little bit before
elessair 0:f269e3021894 308 reconnecting, prevents connection flood, especially when using PPPoL2TP.
elessair 0:f269e3021894 309 - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
elessair 0:f269e3021894 310 feature to lwIP, L2TP being a widely used tunnel protocol.
elessair 0:f269e3021894 311 - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
elessair 0:f269e3021894 312 - Added PPP API "sequential" thread-safe API, based from NETIFAPI.

elessair 0:f269e3021894 319 * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
elessair 0:f269e3021894 320 combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
elessair 0:f269e3021894 321 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
elessair 0:f269e3021894 322 code so that the code is more readable.

elessair 0:f269e3021894 1096 * tcp_impl.h, tcp_in.c, tcp_out.c: Removed 'dataptr' from 'struct tcp_seg' and
elessair 0:f269e3021894 1097 calculate it in tcp_zero_window_probe (the only place where it was used).
elessair 0:f269e3021894 1098
elessair 0:f269e3021894 1099 2010-11-21: Simon Goldschmidt

elessair 0:f269e3021894 1107 2010-06-16: Simon Goldschmidt
elessair 0:f269e3021894 1108 * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
elessair 0:f269e3021894 1109 link-layer-addressed UDP traffic to be received while a netif is down (just
elessair 0:f269e3021894 1110 like DHCP during configuration)
elessair 0:f269e3021894 1111
elessair 0:f269e3021894 1112 2010-05-22: Simon Goldschmidt
elessair 0:f269e3021894 1113 * many many files: bug #27352: removed packing from ip_addr_t, the packed
elessair 0:f269e3021894 1114 version is now only used in protocol headers. Added global storage for
elessair 0:f269e3021894 1115 current src/dest IP address while in input functions.
elessair 0:f269e3021894 1116
elessair 0:f269e3021894 1117 2010-05-16: Simon Goldschmidt
elessair 0:f269e3021894 1118 * def.h: task #10391: Add preprocessor-macros for compile-time htonl
elessair 0:f269e3021894 1119 calculation (and use them throughout the stack where applicable)
elessair 0:f269e3021894 1120
elessair 0:f269e3021894 1121 2010-05-16: Simon Goldschmidt
elessair 0:f269e3021894 1122 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
elessair 0:f269e3021894 1123 instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
elessair 0:f269e3021894 1124
elessair 0:f269e3021894 1125 2010-05-16: Simon Goldschmidt
elessair 0:f269e3021894 1126 * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
elessair 0:f269e3021894 1127 MEMP pool instead of the heap
elessair 0:f269e3021894 1128
elessair 0:f269e3021894 1129 2010-05-13: Simon Goldschmidt
elessair 0:f269e3021894 1130 * tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
elessair 0:f269e3021894 1131 new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
elessair 0:f269e3021894 1132 packets to more than one pcb.
elessair 0:f269e3021894 1133
elessair 0:f269e3021894 1134 2010-05-02: Simon Goldschmidt
elessair 0:f269e3021894 1135 * netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
elessair 0:f269e3021894 1136 UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
elessair 0:f269e3021894 1137
elessair 0:f269e3021894 1138 2010-04-30: Simon Goldschmidt
elessair 0:f269e3021894 1139 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
elessair 0:f269e3021894 1140 take a precalculated checksum, added pbuf_fill_chksum() to copy data
elessair 0:f269e3021894 1141 into a pbuf and at the same time calculating the checksum for that data
elessair 0:f269e3021894 1142
elessair 0:f269e3021894 1143 2010-04-29: Simon Goldschmidt
elessair 0:f269e3021894 1144 * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
elessair 0:f269e3021894 1145 2-byte-aligned IP addresses and MAC addresses
elessair 0:f269e3021894 1146
elessair 0:f269e3021894 1147 2010-04-28: Patch by Bill Auerbach
elessair 0:f269e3021894 1148 * ip.c: Inline generating IP checksum to save a function call
elessair 0:f269e3021894 1149
elessair 0:f269e3021894 1150 2010-04-14: Simon Goldschmidt
elessair 0:f269e3021894 1151 * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
elessair 0:f269e3021894 1152 tcpip_thread processes messages or timeouts to implement a watchdog.
elessair 0:f269e3021894 1153
elessair 0:f269e3021894 1154 2010-03-28: Simon Goldschmidt
elessair 0:f269e3021894 1155 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
elessair 0:f269e3021894 1156 fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
elessair 0:f269e3021894 1157
elessair 0:f269e3021894 1158 2010-03-27: Simon Goldschmidt
elessair 0:f269e3021894 1159 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
elessair 0:f269e3021894 1160 etharp_query to prevent unnecessary function calls (inspired by
elessair 0:f269e3021894 1161 patch #7135).
elessair 0:f269e3021894 1162
elessair 0:f269e3021894 1163 2010-03-20: Simon Goldschmidt
elessair 0:f269e3021894 1164 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
elessair 0:f269e3021894 1165 since the linker cannot do this automatically to save space.
elessair 0:f269e3021894 1166
elessair 0:f269e3021894 1167 2010-03-20: Simon Goldschmidt
elessair 0:f269e3021894 1168 * opt.h, etharp.c/.h: Added support for static ARP table entries
elessair 0:f269e3021894 1169
elessair 0:f269e3021894 1170 2010-03-14: Simon Goldschmidt
elessair 0:f269e3021894 1171 * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
elessair 0:f269e3021894 1172 when creating TCP segments, not when (re-)transmitting them.
elessair 0:f269e3021894 1173
elessair 0:f269e3021894 1174 2010-03-07: Simon Goldschmidt
elessair 0:f269e3021894 1175 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
elessair 0:f269e3021894 1176 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
elessair 0:f269e3021894 1177 This should speed up receiving data on sockets as the select code in
elessair 0:f269e3021894 1178 event_callback is only executed when select is waiting.
elessair 0:f269e3021894 1179
elessair 0:f269e3021894 1180 2010-03-06: Simon Goldschmidt
elessair 0:f269e3021894 1181 * tcp_out.c: task #7013 (Create option to have all packets delivered to

elessair 0:f269e3021894 1183 in tcp_write.
elessair 0:f269e3021894 1184
elessair 0:f269e3021894 1185 2010-03-06: Simon Goldschmidt
elessair 0:f269e3021894 1186 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
elessair 0:f269e3021894 1187 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
elessair 0:f269e3021894 1188 for tcp netconns to receive pbufs, not netbufs; use that function
elessair 0:f269e3021894 1189 for tcp sockets.
elessair 0:f269e3021894 1190
elessair 0:f269e3021894 1191 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
elessair 0:f269e3021894 1192 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
elessair 0:f269e3021894 1193 Work on tcp_enqueue: Don't waste memory when chaining segments,
elessair 0:f269e3021894 1194 added option TCP_OVERSIZE to prevent creating many small pbufs when
elessair 0:f269e3021894 1195 calling tcp_write with many small blocks of data. Instead, pbufs are
elessair 0:f269e3021894 1196 allocated larger than needed and the space is used for later calls to
elessair 0:f269e3021894 1197 tcp_write.
elessair 0:f269e3021894 1198
elessair 0:f269e3021894 1199 2010-02-21: Simon Goldschmidt
elessair 0:f269e3021894 1200 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
elessair 0:f269e3021894 1201 debugging.
elessair 0:f269e3021894 1202
elessair 0:f269e3021894 1203 2010-02-21: Simon Goldschmidt
elessair 0:f269e3021894 1204 * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
elessair 0:f269e3021894 1205 implementation of tcp to make API usage cleare to application programmers
elessair 0:f269e3021894 1206
elessair 0:f269e3021894 1207 2010-02-14: Simon Goldschmidt/Stephane Lesage
elessair 0:f269e3021894 1208 * ip_addr.h: Improved some defines working on ip addresses, added faster
elessair 0:f269e3021894 1209 macro to copy addresses that cannot be NULL
elessair 0:f269e3021894 1210
elessair 0:f269e3021894 1211 2010-02-13: Simon Goldschmidt
elessair 0:f269e3021894 1212 * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
elessair 0:f269e3021894 1213 blocking send operation)
elessair 0:f269e3021894 1214
elessair 0:f269e3021894 1215 2010-02-12: Simon Goldschmidt
elessair 0:f269e3021894 1216 * sockets.c/.h: Added a minimal version of posix fctl() to have a
elessair 0:f269e3021894 1217 standardised way to set O_NONBLOCK for nonblocking sockets.
elessair 0:f269e3021894 1218
elessair 0:f269e3021894 1219 2010-02-12: Simon Goldschmidt
elessair 0:f269e3021894 1220 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
elessair 0:f269e3021894 1221 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
elessair 0:f269e3021894 1222 and dhcp work with user-allocated structs instead of callin mem_malloc
elessair 0:f269e3021894 1223
elessair 0:f269e3021894 1224 2010-02-12: Simon Goldschmidt/Jeff Barber
elessair 0:f269e3021894 1225 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
elessair 0:f269e3021894 1226 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
elessair 0:f269e3021894 1227
elessair 0:f269e3021894 1228 2010-02-12: Simon Goldschmidt
elessair 0:f269e3021894 1229 * sys layer: task #10139 (Prefer statically allocated memory): converted
elessair 0:f269e3021894 1230 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
elessair 0:f269e3021894 1231 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
elessair 0:f269e3021894 1232 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
elessair 0:f269e3021894 1233 to let sys.h use binary semaphores instead of mutexes - as before)
elessair 0:f269e3021894 1234
elessair 0:f269e3021894 1235 2010-02-09: Simon Goldschmidt (Simon Kallweit)

elessair 0:f269e3021894 1239 2010-02-09: Simon Goldschmidt
elessair 0:f269e3021894 1240 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
elessair 0:f269e3021894 1241 netif.c) - loopif does not have to be created by the port any more,
elessair 0:f269e3021894 1242 just define LWIP_HAVE_LOOPIF to 1.
elessair 0:f269e3021894 1243
elessair 0:f269e3021894 1244 2010-02-08: Simon Goldschmidt
elessair 0:f269e3021894 1245 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
elessair 0:f269e3021894 1246 inet_ntoa_r/ipaddr_ntoa_r
elessair 0:f269e3021894 1247
elessair 0:f269e3021894 1248 2010-02-08: Simon Goldschmidt
elessair 0:f269e3021894 1249 * netif.h: Added netif_s/get_igmp_mac_filter() macros
elessair 0:f269e3021894 1250
elessair 0:f269e3021894 1251 2010-02-05: Simon Goldschmidt
elessair 0:f269e3021894 1252 * netif.h: Added function-like macros to get/set the hostname on a netif
elessair 0:f269e3021894 1253
elessair 0:f269e3021894 1254 2010-02-04: Simon Goldschmidt
elessair 0:f269e3021894 1255 * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
elessair 0:f269e3021894 1256 make changing the actual implementation behind the typedef easier.
elessair 0:f269e3021894 1257
elessair 0:f269e3021894 1258 2010-02-01: Simon Goldschmidt
elessair 0:f269e3021894 1259 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
elessair 0:f269e3021894 1260 for allocating memory when getaddrinfo() is called.
elessair 0:f269e3021894 1261
elessair 0:f269e3021894 1262 2010-01-31: Simon Goldschmidt
elessair 0:f269e3021894 1263 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
elessair 0:f269e3021894 1264 them once instead of parsing for every option. This also removes
elessair 0:f269e3021894 1265 the need for mem_malloc from dhcp_recv and makes it possible to
elessair 0:f269e3021894 1266 correctly retrieve the BOOTP file.

elessair 0:f269e3021894 1268 2010-01-30: simon Goldschmidt
elessair 0:f269e3021894 1269 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
elessair 0:f269e3021894 1270 the sockets array.
elessair 0:f269e3021894 1271
elessair 0:f269e3021894 1272 2010-01-29: Simon Goldschmidt (patch by Laura Garrett)

elessair 0:f269e3021894 1288 2010-01-14: Simon Goldschmidt
elessair 0:f269e3021894 1289 * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
elessair 0:f269e3021894 1290 by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()

elessair 0:f269e3021894 2314 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
elessair 0:f269e3021894 2315 indicate the number of pointers query by the mailbox. There is three defines
elessair 0:f269e3021894 2316 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
elessair 0:f269e3021894 2317 netconn::acceptmbox. Port maintainers, you can decide to just add this new

elessair 0:f269e3021894 2319 The new sys_mbox_trypost function return a value to know if the mailbox is
elessair 0:f269e3021894 2320 full or if the message is posted. Take a look to sys_arch.txt for more details.
elessair 0:f269e3021894 2321 This new function is used in tcpip_input (so, can be called in an interrupt
elessair 0:f269e3021894 2322 context since the function is not blocking), and in recv_udp and recv_raw.

elessair 0:f269e3021894 2336 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be

elessair 0:f269e3021894 2363 2007-12-03 Simon Goldschmidt
elessair 0:f269e3021894 2364 * ip.c: ip_input: check if a packet is for inp first before checking all other
elessair 0:f269e3021894 2365 netifs on netif_list (speeds up packet receiving in most cases)
elessair 0:f269e3021894 2366
elessair 0:f269e3021894 2367 2007-11-30 Simon Goldschmidt
elessair 0:f269e3021894 2368 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
elessair 0:f269e3021894 2369 UDP: move a (connected) pcb selected for input to the front of the list of
elessair 0:f269e3021894 2370 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
elessair 0:f269e3021894 2371 a packet.
elessair 0:f269e3021894 2372
elessair 0:f269e3021894 2373 2007-11-28 Simon Goldschmidt
elessair 0:f269e3021894 2374 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
elessair 0:f269e3021894 2375
elessair 0:f269e3021894 2376 2007-11-25 Simon Goldschmidt
elessair 0:f269e3021894 2377 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
elessair 0:f269e3021894 2378 algorithm.
elessair 0:f269e3021894 2379
elessair 0:f269e3021894 2380 2007-11-24 Simon Goldschmidt
elessair 0:f269e3021894 2381 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
elessair 0:f269e3021894 2382 to the new file netdb.c; included lwip_getaddrinfo.
elessair 0:f269e3021894 2383
elessair 0:f269e3021894 2384 2007-11-21 Simon Goldschmidt
elessair 0:f269e3021894 2385 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
elessair 0:f269e3021894 2386 based on the MTU of the netif used to send. Enabled by default. Disable by
elessair 0:f269e3021894 2387 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
elessair 0:f269e3021894 2388
elessair 0:f269e3021894 2389 2007-11-19 Frédéric Bernon
elessair 0:f269e3021894 2390 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
elessair 0:f269e3021894 2391 received match the name query), implement DNS_USES_STATIC_BUF (the place where
elessair 0:f269e3021894 2392 copy dns payload to parse the response), return an error if there is no place
elessair 0:f269e3021894 2393 for a new query, and fix some minor problems.
elessair 0:f269e3021894 2394
elessair 0:f269e3021894 2395 2007-11-16 Simon Goldschmidt
elessair 0:f269e3021894 2396 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
elessair 0:f269e3021894 2397 removed files: core/inet.c, core/inet6.c
elessair 0:f269e3021894 2398 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
elessair 0:f269e3021894 2399 inet and chksum part; changed includes in all lwIP files as appropriate
elessair 0:f269e3021894 2400
elessair 0:f269e3021894 2401 2007-11-16 Simon Goldschmidt
elessair 0:f269e3021894 2402 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
elessair 0:f269e3021894 2403 dns resolver function for netconn api (netconn_gethostbyname) and socket api
elessair 0:f269e3021894 2404 (gethostbyname/gethostbyname_r).
elessair 0:f269e3021894 2405
elessair 0:f269e3021894 2406 2007-11-15 Jim Pettinato, Frédéric Bernon
elessair 0:f269e3021894 2407 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
elessair 0:f269e3021894 2408 requests with RAW api interface. Initialization is done in lwip_init() with
elessair 0:f269e3021894 2409 build time options. DNS timer is added in tcpip_thread context. DHCP can set
elessair 0:f269e3021894 2410 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
elessair 0:f269e3021894 2411 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
elessair 0:f269e3021894 2412 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
elessair 0:f269e3021894 2413 list with points to improve.
elessair 0:f269e3021894 2414
elessair 0:f269e3021894 2415 2007-11-06 Simon Goldschmidt
elessair 0:f269e3021894 2416 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
elessair 0:f269e3021894 2417 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
elessair 0:f269e3021894 2418 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
elessair 0:f269e3021894 2419
elessair 0:f269e3021894 2420 2007-11-06 Simon Goldschmidt
elessair 0:f269e3021894 2421 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
elessair 0:f269e3021894 2422 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
elessair 0:f269e3021894 2423 implementation from netconn api applications.
elessair 0:f269e3021894 2424
elessair 0:f269e3021894 2425 2007-11-03 Frédéric Bernon
elessair 0:f269e3021894 2426 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
elessair 0:f269e3021894 2427 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
elessair 0:f269e3021894 2428 by default). Netconn API users can use the netconn_recv_bufsize macro to access
elessair 0:f269e3021894 2429 it. This is a first release which have to be improve for TCP. Note it used the
elessair 0:f269e3021894 2430 netconn::recv_avail which need to be more "thread-safe" (note there is already
elessair 0:f269e3021894 2431 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
elessair 0:f269e3021894 2432
elessair 0:f269e3021894 2433 2007-11-01 Frédéric Bernon, Marc Chaland
elessair 0:f269e3021894 2434 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
elessair 0:f269e3021894 2435 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
elessair 0:f269e3021894 2436 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
elessair 0:f269e3021894 2437 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
elessair 0:f269e3021894 2438 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
elessair 0:f269e3021894 2439
elessair 0:f269e3021894 2440 2007-10-24 Frédéric Bernon
elessair 0:f269e3021894 2441 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
elessair 0:f269e3021894 2442 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
elessair 0:f269e3021894 2443 some code (like we have talk in "patch #5919 : Create compile switch to remove
elessair 0:f269e3021894 2444 select code"), but it could be done later.
elessair 0:f269e3021894 2445
elessair 0:f269e3021894 2446 2007-10-08 Simon Goldschmidt
elessair 0:f269e3021894 2447 * many files: Changed initialization: many init functions are not needed any
elessair 0:f269e3021894 2448 more since we now rely on the compiler initializing global and static
elessair 0:f269e3021894 2449 variables to zero!
elessair 0:f269e3021894 2450
elessair 0:f269e3021894 2451 2007-10-06 Simon Goldschmidt
elessair 0:f269e3021894 2452 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
elessair 0:f269e3021894 2453 to enqueue the received pbufs so that multiple packets can be reassembled
elessair 0:f269e3021894 2454 simultaneously and no static reassembly buffer is needed.
elessair 0:f269e3021894 2455
elessair 0:f269e3021894 2456 2007-10-05 Simon Goldschmidt
elessair 0:f269e3021894 2457 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
elessair 0:f269e3021894 2458 all netifs (or ports) can use it.
elessair 0:f269e3021894 2459
elessair 0:f269e3021894 2460 2007-10-05 Frédéric Bernon
elessair 0:f269e3021894 2461 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
elessair 0:f269e3021894 2462 common function to reduce a little bit the footprint (for all functions using
elessair 0:f269e3021894 2463 only the "netif" parameter).
elessair 0:f269e3021894 2464
elessair 0:f269e3021894 2465 2007-10-03 Frédéric Bernon
elessair 0:f269e3021894 2466 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
elessair 0:f269e3021894 2467 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
elessair 0:f269e3021894 2468 a little bit the footprint (for all functions using only the "netif" parameter).
elessair 0:f269e3021894 2469
elessair 0:f269e3021894 2470 2007-09-15 Frédéric Bernon
elessair 0:f269e3021894 2471 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
elessair 0:f269e3021894 2472 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
elessair 0:f269e3021894 2473 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
elessair 0:f269e3021894 2474 IP_MULTICAST_TTL and IP_MULTICAST_IF.
elessair 0:f269e3021894 2475
elessair 0:f269e3021894 2476 2007-09-10 Frédéric Bernon
elessair 0:f269e3021894 2477 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
elessair 0:f269e3021894 2478 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
elessair 0:f269e3021894 2479 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
elessair 0:f269e3021894 2480 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
elessair 0:f269e3021894 2481 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
elessair 0:f269e3021894 2482 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
elessair 0:f269e3021894 2483 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
elessair 0:f269e3021894 2484 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
elessair 0:f269e3021894 2485 when it's queried (any direct call to "sysuptime" is changed by a call to
elessair 0:f269e3021894 2486 snmp_get_sysuptime).
elessair 0:f269e3021894 2487
elessair 0:f269e3021894 2488 2007-09-09 Frédéric Bernon, Bill Florac
elessair 0:f269e3021894 2489 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
elessair 0:f269e3021894 2490 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
elessair 0:f269e3021894 2491 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
elessair 0:f269e3021894 2492 igmp_report_groups() is now called inside netif_set_link_up() (need to have
elessair 0:f269e3021894 2493 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
elessair 0:f269e3021894 2494 the next query message to receive the matching multicast streams).
elessair 0:f269e3021894 2495
elessair 0:f269e3021894 2496 2007-09-08 Frédéric Bernon
elessair 0:f269e3021894 2497 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
elessair 0:f269e3021894 2498 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
elessair 0:f269e3021894 2499 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
elessair 0:f269e3021894 2500 Enable to access to these fields with LWIP_TCP=0.
elessair 0:f269e3021894 2501
elessair 0:f269e3021894 2502 2007-09-05 Frédéric Bernon
elessair 0:f269e3021894 2503 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
elessair 0:f269e3021894 2504 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
elessair 0:f269e3021894 2505 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
elessair 0:f269e3021894 2506 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
elessair 0:f269e3021894 2507 help to reduce footprint, and to reduce "visibility" on the Internet.
elessair 0:f269e3021894 2508

elessair 0:f269e3021894 2510 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
elessair 0:f269e3021894 2511 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
elessair 0:f269e3021894 2512 parameters have to be provided: a task name, and a task stack size. For this
elessair 0:f269e3021894 2513 one, since it's platform dependant, you could define the best one for you in
elessair 0:f269e3021894 2514 your lwipopts.h. For port maintainers, you can just add these new parameters
elessair 0:f269e3021894 2515 in your sys_arch.c file, and but it's not mandatory, use them in your OS
elessair 0:f269e3021894 2516 specific functions.
elessair 0:f269e3021894 2517
elessair 0:f269e3021894 2518 2007-09-05 Frédéric Bernon
elessair 0:f269e3021894 2519 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
elessair 0:f269e3021894 2520 inside init.c for task #7142 "Sanity check user-configurable values".
elessair 0:f269e3021894 2521

elessair 0:f269e3021894 2523 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
elessair 0:f269e3021894 2524 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
elessair 0:f269e3021894 2525 value). It will avoid potential fragmentation problems, use a counter to know
elessair 0:f269e3021894 2526 how many times a group is used on an netif, and free it when all applications
elessair 0:f269e3021894 2527 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
elessair 0:f269e3021894 2528 check if LWIP_IGMP!=0).
elessair 0:f269e3021894 2529
elessair 0:f269e3021894 2530 2007-09-03 Frédéric Bernon
elessair 0:f269e3021894 2531 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
elessair 0:f269e3021894 2532 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
elessair 0:f269e3021894 2533 the netif's "init" function). Use the "imr_interface" field (for socket layer)
elessair 0:f269e3021894 2534 and/or the "interface" field (for netconn layer), for join/leave operations.
elessair 0:f269e3021894 2535 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
elessair 0:f269e3021894 2536 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
elessair 0:f269e3021894 2537
elessair 0:f269e3021894 2538 2007-08-30 Frédéric Bernon
elessair 0:f269e3021894 2539 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
elessair 0:f269e3021894 2540 from api/api_lib". Now netbuf API is independant of netconn, and can be used
elessair 0:f269e3021894 2541 with other API (application based on raw API, or future "socket2" API). Ports
elessair 0:f269e3021894 2542 maintainers just have to add src/api/netbuf.c in their makefile/projects.

elessair 0:f269e3021894 2545 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
elessair 0:f269e3021894 2546 user-configurable values".
elessair 0:f269e3021894 2547

elessair 0:f269e3021894 2549 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
elessair 0:f269e3021894 2550 igmp_start is call inside netif_add. Now, igmp initialization is in the same
elessair 0:f269e3021894 2551 spirit than the others modules. Modify some IGMP debug traces.

elessair 0:f269e3021894 2553 2007-08-29 Frédéric Bernon
elessair 0:f269e3021894 2554 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
elessair 0:f269e3021894 2555 Add lwip_init function to regroup all modules initializations, and to provide
elessair 0:f269e3021894 2556 a place to add code for task #7142 "Sanity check user-configurable values".
elessair 0:f269e3021894 2557 Ports maintainers should remove direct initializations calls from their code,
elessair 0:f269e3021894 2558 and add init.c in their makefiles. Note that lwip_init() function is called
elessair 0:f269e3021894 2559 inside tcpip_init, but can also be used by raw api users since all calls are
elessair 0:f269e3021894 2560 disabled when matching options are disabled. Also note that their is new options
elessair 0:f269e3021894 2561 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
elessair 0:f269e3021894 2562
elessair 0:f269e3021894 2563 2007-08-26 Marc Boucher
elessair 0:f269e3021894 2564 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
elessair 0:f269e3021894 2565 since they can under certain circumstances be called with an invalid conn
elessair 0:f269e3021894 2566 pointer after the connection has been closed (and conn has been freed).
elessair 0:f269e3021894 2567
elessair 0:f269e3021894 2568 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
elessair 0:f269e3021894 2569 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
elessair 0:f269e3021894 2570 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
elessair 0:f269e3021894 2571
elessair 0:f269e3021894 2572 2007-08-22 Frédéric Bernon
elessair 0:f269e3021894 2573 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
elessair 0:f269e3021894 2574 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
elessair 0:f269e3021894 2575
elessair 0:f269e3021894 2576 2007-08-22 Frédéric Bernon
elessair 0:f269e3021894 2577 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
elessair 0:f269e3021894 2578 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
elessair 0:f269e3021894 2579 name is tcpip_input (we keep the name of 1.2.0 function).
elessair 0:f269e3021894 2580
elessair 0:f269e3021894 2581 2007-08-17 Jared Grubb
elessair 0:f269e3021894 2582 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
elessair 0:f269e3021894 2583 settings into new memp_std.h and optional user file lwippools.h. This adds
elessair 0:f269e3021894 2584 more dynamic mempools, and allows the user to create an arbitrary number of
elessair 0:f269e3021894 2585 mempools for mem_malloc.
elessair 0:f269e3021894 2586
elessair 0:f269e3021894 2587 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2588 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
elessair 0:f269e3021894 2589 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
elessair 0:f269e3021894 2590 close the connection.
elessair 0:f269e3021894 2591
elessair 0:f269e3021894 2592 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2593 * sockets.c: lwip_accept(): check netconn_peer() error return.
elessair 0:f269e3021894 2594
elessair 0:f269e3021894 2595 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2596 * mem.c, mem.h: Added mem_calloc().
elessair 0:f269e3021894 2597
elessair 0:f269e3021894 2598 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2599 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
elessair 0:f269e3021894 2600 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
elessair 0:f269e3021894 2601 and starving other message types.
elessair 0:f269e3021894 2602 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
elessair 0:f269e3021894 2603
elessair 0:f269e3021894 2604 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2605 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
elessair 0:f269e3021894 2606 type and flgs (later renamed to flags).
elessair 0:f269e3021894 2607 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
elessair 0:f269e3021894 2608 Improved lwip_recvfrom(). TCP push now propagated.
elessair 0:f269e3021894 2609
elessair 0:f269e3021894 2610 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2611 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
elessair 0:f269e3021894 2612 provided by etharp.
elessair 0:f269e3021894 2613
elessair 0:f269e3021894 2614 2007-08-16 Marc Boucher
elessair 0:f269e3021894 2615 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
elessair 0:f269e3021894 2616 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
elessair 0:f269e3021894 2617 Added PPPoE support and various PPP improvements.
elessair 0:f269e3021894 2618
elessair 0:f269e3021894 2619 2007-07-25 Simon Goldschmidt
elessair 0:f269e3021894 2620 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
elessair 0:f269e3021894 2621 making netbuf_copy_partial use this function.
elessair 0:f269e3021894 2622
elessair 0:f269e3021894 2623 2007-07-25 Simon Goldschmidt
elessair 0:f269e3021894 2624 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
elessair 0:f269e3021894 2625 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
elessair 0:f269e3021894 2626 other stacks.
elessair 0:f269e3021894 2627
elessair 0:f269e3021894 2628 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
elessair 0:f269e3021894 2629 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
elessair 0:f269e3021894 2630 a link callback in the netif struct, and functions to handle it. Be carefull
elessair 0:f269e3021894 2631 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
elessair 0:f269e3021894 2632 if you want to be sure to be compatible with future changes...
elessair 0:f269e3021894 2633
elessair 0:f269e3021894 2634 2007-06-30 Frédéric Bernon
elessair 0:f269e3021894 2635 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
elessair 0:f269e3021894 2636
elessair 0:f269e3021894 2637 2007-06-21 Simon Goldschmidt
elessair 0:f269e3021894 2638 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
elessair 0:f269e3021894 2639 LWIP_AUTOIP =0 and =1 to remove redundant code.
elessair 0:f269e3021894 2640
elessair 0:f269e3021894 2641 2007-06-21 Simon Goldschmidt
elessair 0:f269e3021894 2642 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
elessair 0:f269e3021894 2643 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
elessair 0:f269e3021894 2644 heap. This both prevents memory fragmentation and gives a higher speed
elessair 0:f269e3021894 2645 at the cost of more memory consumption. Turned off by default.
elessair 0:f269e3021894 2646
elessair 0:f269e3021894 2647 2007-06-21 Simon Goldschmidt
elessair 0:f269e3021894 2648 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
elessair 0:f269e3021894 2649 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
elessair 0:f269e3021894 2650 int to be able to send a bigger buffer than 64K with one time (mainly
elessair 0:f269e3021894 2651 used from lwip_send).
elessair 0:f269e3021894 2652
elessair 0:f269e3021894 2653 2007-06-21 Simon Goldschmidt
elessair 0:f269e3021894 2654 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
elessair 0:f269e3021894 2655 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
elessair 0:f269e3021894 2656
elessair 0:f269e3021894 2657 2007-06-21 Simon Goldschmidt
elessair 0:f269e3021894 2658 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
elessair 0:f269e3021894 2659 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
elessair 0:f269e3021894 2660 changes on low memory or empty send-buffer.
elessair 0:f269e3021894 2661
elessair 0:f269e3021894 2662 2007-06-18 Simon Goldschmidt
elessair 0:f269e3021894 2663 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
elessair 0:f269e3021894 2664 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
elessair 0:f269e3021894 2665 used for ethernet and struct eth_addr already had a defined length of 6).
elessair 0:f269e3021894 2666
elessair 0:f269e3021894 2667 2007-06-17 Simon Goldschmidt
elessair 0:f269e3021894 2668 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
elessair 0:f269e3021894 2669 to disable UDP checksum generation on transmit.
elessair 0:f269e3021894 2670
elessair 0:f269e3021894 2671 2007-06-13 Frédéric Bernon, Simon Goldschmidt
elessair 0:f269e3021894 2672 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
elessair 0:f269e3021894 2673 pointers or parameters, and let the possibility to redefined it in cc.h. Use
elessair 0:f269e3021894 2674 this macro to check "conn" parameter in api_msg.c functions.
elessair 0:f269e3021894 2675
elessair 0:f269e3021894 2676 2007-06-11 Simon Goldschmidt
elessair 0:f269e3021894 2677 * sockets.c, sockets.h: Added UDP lite support for sockets
elessair 0:f269e3021894 2678
elessair 0:f269e3021894 2679 2007-06-10 Simon Goldschmidt
elessair 0:f269e3021894 2680 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
elessair 0:f269e3021894 2681 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
elessair 0:f269e3021894 2682 size)
elessair 0:f269e3021894 2683
elessair 0:f269e3021894 2684 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
elessair 0:f269e3021894 2685 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
elessair 0:f269e3021894 2686 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
elessair 0:f269e3021894 2687 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
elessair 0:f269e3021894 2688 (see TODO mark in the source code).
elessair 0:f269e3021894 2689
elessair 0:f269e3021894 2690 2007-06-09 Simon Goldschmidt
elessair 0:f269e3021894 2691 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
elessair 0:f269e3021894 2692 etharp_output() to match netif->output so etharp_output() can be used
elessair 0:f269e3021894 2693 directly as netif->output to save one function call.
elessair 0:f269e3021894 2694
elessair 0:f269e3021894 2695 2007-06-08 Simon Goldschmidt
elessair 0:f269e3021894 2696 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
elessair 0:f269e3021894 2697 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
elessair 0:f269e3021894 2698 added initialization of those to ethernetif, slipif and loopif.
elessair 0:f269e3021894 2699
elessair 0:f269e3021894 2700 2007-05-18 Simon Goldschmidt
elessair 0:f269e3021894 2701 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
elessair 0:f269e3021894 2702 (defaulting to off for now) that can be set to 0 to send fragmented
elessair 0:f269e3021894 2703 packets by passing PBUF_REFs down the stack.
elessair 0:f269e3021894 2704
elessair 0:f269e3021894 2705 2007-05-23 Frédéric Bernon
elessair 0:f269e3021894 2706 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
elessair 0:f269e3021894 2707 connections, such present in patch #5959.
elessair 0:f269e3021894 2708
elessair 0:f269e3021894 2709 2007-05-23 Frédéric Bernon
elessair 0:f269e3021894 2710 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
elessair 0:f269e3021894 2711 code in only one part...
elessair 0:f269e3021894 2712
elessair 0:f269e3021894 2713 2007-05-18 Simon Goldschmidt
elessair 0:f269e3021894 2714 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
elessair 0:f269e3021894 2715 elements to overflow. This is achieved by adding some bytes before and after
elessair 0:f269e3021894 2716 each pool element (increasing their size, of course), filling them with a
elessair 0:f269e3021894 2717 prominent value and checking them on freeing the element.
elessair 0:f269e3021894 2718 Set it to 2 to also check every element in every pool each time memp_malloc()
elessair 0:f269e3021894 2719 or memp_free() is called (slower but more helpful).
elessair 0:f269e3021894 2720
elessair 0:f269e3021894 2721 2007-05-10 Simon Goldschmidt
elessair 0:f269e3021894 2722 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
elessair 0:f269e3021894 2723 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
elessair 0:f269e3021894 2724 code size.
elessair 0:f269e3021894 2725
elessair 0:f269e3021894 2726 2007-05-11 Frédéric Bernon
elessair 0:f269e3021894 2727 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
elessair 0:f269e3021894 2728 Include a function pointer instead of a table index in the message to reduce
elessair 0:f269e3021894 2729 footprint. Disable some part of lwip_send and lwip_sendto if some options are
elessair 0:f269e3021894 2730 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
elessair 0:f269e3021894 2731
elessair 0:f269e3021894 2732 2007-05-10 Simon Goldschmidt
elessair 0:f269e3021894 2733 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
elessair 0:f269e3021894 2734 \ extern "C" {' in all header files. Now you can write your application using
elessair 0:f269e3021894 2735 the lwIP stack in C++ and simply #include the core files. Note I have left
elessair 0:f269e3021894 2736 out the netif/ppp/*h header files for now, since I don't know which files are
elessair 0:f269e3021894 2737 included by applications and which are for internal use only.

elessair 0:f269e3021894 2740 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
elessair 0:f269e3021894 2741 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
elessair 0:f269e3021894 2742 situations where some compilers might inline the copy and save a function
elessair 0:f269e3021894 2743 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().

elessair 0:f269e3021894 2745 2007-05-08 Simon Goldschmidt
elessair 0:f269e3021894 2746 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
elessair 0:f269e3021894 2747 to be overriden in case the C-library malloc implementation is not protected
elessair 0:f269e3021894 2748 against concurrent access.

elessair 0:f269e3021894 2751 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
elessair 0:f269e3021894 2752 multiple packets to the same host.
elessair 0:f269e3021894 2753

elessair 0:f269e3021894 2755 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
elessair 0:f269e3021894 2756 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
elessair 0:f269e3021894 2757 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between

elessair 0:f269e3021894 2763 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
elessair 0:f269e3021894 2764 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
elessair 0:f269e3021894 2765 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
elessair 0:f269e3021894 2766 by the port in sys_arch.h if desired.

elessair 0:f269e3021894 2769 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
elessair 0:f269e3021894 2770 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
elessair 0:f269e3021894 2771 clients, using new functions from netifapi.h. Disable as default (no port change to do).

elessair 0:f269e3021894 2773 2007-04-05 Frédéric Bernon
elessair 0:f269e3021894 2774 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
elessair 0:f269e3021894 2775
elessair 0:f269e3021894 2776 2007-04-04 Simon Goldschmidt
elessair 0:f269e3021894 2777 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
elessair 0:f269e3021894 2778 use this for and architecture-independent form to tell the compiler you intentionally
elessair 0:f269e3021894 2779 are not using this variable. Can be overriden in cc.h.

elessair 0:f269e3021894 2781 2007-03-28 Frédéric Bernon
elessair 0:f269e3021894 2782 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
elessair 0:f269e3021894 2783 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
elessair 0:f269e3021894 2784 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
elessair 0:f269e3021894 2785 It will be used by DHCP to register a client hostname, but can also be use when you call
elessair 0:f269e3021894 2786 snmp_set_sysname.

elessair 0:f269e3021894 2788 2007-03-28 Frédéric Bernon
elessair 0:f269e3021894 2789 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
elessair 0:f269e3021894 2790 initialize a network interface's flag with. It tell this interface is an ethernet
elessair 0:f269e3021894 2791 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
elessair 0:f269e3021894 2792 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().

elessair 0:f269e3021894 2795 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
elessair 0:f269e3021894 2796 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
elessair 0:f269e3021894 2797 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
elessair 0:f269e3021894 2798 is done in tcpip_init function.

elessair 0:f269e3021894 2801 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
elessair 0:f269e3021894 2802 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
elessair 0:f269e3021894 2803 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
elessair 0:f269e3021894 2804 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
elessair 0:f269e3021894 2805 but never used. Fix msg_in.c with the correct #if test for a stat display.

elessair 0:f269e3021894 2814 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
elessair 0:f269e3021894 2815 filter per all network interfaces. Declare a new function in netif to enable to

elessair 0:f269e3021894 2819 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
elessair 0:f269e3021894 2820 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
elessair 0:f269e3021894 2821 unless you know what you're doing (default are RFC1122 compliant). Note

elessair 0:f269e3021894 2846 lwip_socket_init() function.
elessair 0:f269e3021894 2847 NOTE: this changes the API with ports. Ports will have to be

elessair 0:f269e3021894 2857 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
elessair 0:f269e3021894 2858 some problems to fill the IP header on some targets, use now the

elessair 0:f269e3021894 2862 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
elessair 0:f269e3021894 2863 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
elessair 0:f269e3021894 2864 TCP connection caused a crash. Note that using (lwip_)recvfrom
elessair 0:f269e3021894 2865 like this is a bit slow and that using (lwip)getpeername is the
elessair 0:f269e3021894 2866 good lwip way to do it (so, using recv is faster on tcp sockets).

elessair 0:f269e3021894 2869 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
elessair 0:f269e3021894 2870 recv_raw() does not consume data", and the ping sample (with
elessair 0:f269e3021894 2871 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
elessair 0:f269e3021894 2872 returned the IP payload, without the IP header).

elessair 0:f269e3021894 2926 This is a fix for thread-safety and allocates all items needed for a netconn

elessair 0:f269e3021894 2936 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by

elessair 0:f269e3021894 2940 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
elessair 0:f269e3021894 2941 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
elessair 0:f269e3021894 2942 sockets block most operations once they have seen a fatal error.

elessair 0:f269e3021894 2953 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
elessair 0:f269e3021894 2954 Fixed the nagle algorithm; nagle now also works for all raw API applications
elessair 0:f269e3021894 2955 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'

elessair 0:f269e3021894 2957 2007-11-12 Frédéric Bernon
elessair 0:f269e3021894 2958 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most

elessair 0:f269e3021894 2963 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
elessair 0:f269e3021894 2964 happen any time). Now the packet simply isn't enqueued when out of memory.

elessair 0:f269e3021894 2966 2007-11-01 Simon Goldschmidt
elessair 0:f269e3021894 2967 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
elessair 0:f269e3021894 2968 TCP_MSS if that is smaller) as long as no MSS option is received from the
elessair 0:f269e3021894 2969 remote host.

elessair 0:f269e3021894 2971 2007-11-01 Simon Goldschmidt
elessair 0:f269e3021894 2972 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
elessair 0:f269e3021894 2973 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
elessair 0:f269e3021894 2974 sending our configured TCP_MSS instead of the one received).

elessair 0:f269e3021894 2976 2007-11-01 Simon Goldschmidt
elessair 0:f269e3021894 2977 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
elessair 0:f269e3021894 2978 calculated based on the configured TCP_MSS, not on the MSS option received
elessair 0:f269e3021894 2979 with SYN+ACK.

elessair 0:f269e3021894 2981 2007-10-09 Simon Goldschmidt
elessair 0:f269e3021894 2982 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
elessair 0:f269e3021894 2983 short and also was generated wrong if checksum coverage != tot_len;
elessair 0:f269e3021894 2984 receive: checksum was calculated wrong if checksum coverage != tot_len

elessair 0:f269e3021894 2989 2007-10-07 Frédéric Bernon
elessair 0:f269e3021894 2990 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
elessair 0:f269e3021894 2991 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
elessair 0:f269e3021894 2992 this change cause an API breakage for netconn_addr, since a parameter
elessair 0:f269e3021894 2993 type change. Any compiler should cause an error without any changes in
elessair 0:f269e3021894 2994 yours netconn_peer calls (so, it can't be a "silent change"). It also
elessair 0:f269e3021894 2995 reduce a little bit the footprint for socket layer (lwip_getpeername &
elessair 0:f269e3021894 2996 lwip_getsockname use now a common lwip_getaddrname function since
elessair 0:f269e3021894 2997 netconn_peer & netconn_addr have the same parameters).

elessair 0:f269e3021894 3000 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
elessair 0:f269e3021894 3001 by checking tcp_tw_pcbs also
elessair 0:f269e3021894 3002

elessair 0:f269e3021894 3006 2007-09-15 Mike Kleshov
elessair 0:f269e3021894 3007 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
elessair 0:f269e3021894 3008
elessair 0:f269e3021894 3009 2007-09-06 Frédéric Bernon
elessair 0:f269e3021894 3010 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
elessair 0:f269e3021894 3011 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
elessair 0:f269e3021894 3012 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
elessair 0:f269e3021894 3013 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.

elessair 0:f269e3021894 3015 2007-08-30 Frédéric Bernon
elessair 0:f269e3021894 3016 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
elessair 0:f269e3021894 3017 and fix some coding style.
elessair 0:f269e3021894 3018
elessair 0:f269e3021894 3019 2007-08-28 Frédéric Bernon
elessair 0:f269e3021894 3020 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
elessair 0:f269e3021894 3021 kind of packets. These packets are considered like Ethernet packets (payload
elessair 0:f269e3021894 3022 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
elessair 0:f269e3021894 3023 are considered like IP packets (payload pointing to iphdr).

elessair 0:f269e3021894 3025 2007-08-27 Frédéric Bernon
elessair 0:f269e3021894 3026 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
elessair 0:f269e3021894 3027 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
elessair 0:f269e3021894 3028 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
elessair 0:f269e3021894 3029
elessair 0:f269e3021894 3030 2007-08-24 Kieran Mansley
elessair 0:f269e3021894 3031 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
elessair 0:f269e3021894 3032 compiler (Paradigm C++)
elessair 0:f269e3021894 3033

elessair 0:f269e3021894 3035 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
elessair 0:f269e3021894 3036 Introduce IGMP_STATS to centralize statistics management.

elessair 0:f269e3021894 3039 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
elessair 0:f269e3021894 3040 packet on a udp pcb binded on an netif's IP address, and not on "any".

elessair 0:f269e3021894 3043 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
elessair 0:f269e3021894 3044 This is mainly on using lookup/lookfor, and some coding styles...

elessair 0:f269e3021894 3049 2007-07-25 Simon Goldschmidt
elessair 0:f269e3021894 3050 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
elessair 0:f269e3021894 3051 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
elessair 0:f269e3021894 3052 (tcp_output is called again later from tcp timers).
elessair 0:f269e3021894 3053
elessair 0:f269e3021894 3054 2007-07-25 Simon Goldschmidt
elessair 0:f269e3021894 3055 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
elessair 0:f269e3021894 3056 copy_from_pbuf, which illegally modified the given pbuf.
elessair 0:f269e3021894 3057
elessair 0:f269e3021894 3058 2007-07-25 Simon Goldschmidt
elessair 0:f269e3021894 3059 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
elessair 0:f269e3021894 3060 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).

elessair 0:f269e3021894 3062 2007-07-24 Simon Goldschmidt
elessair 0:f269e3021894 3063 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the

elessair 0:f269e3021894 3067 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
elessair 0:f269e3021894 3068 allocation. It now returns NULL.
elessair 0:f269e3021894 3069

elessair 0:f269e3021894 3071 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
elessair 0:f269e3021894 3072 all error cases.
elessair 0:f269e3021894 3073
elessair 0:f269e3021894 3074 2007-07-13 Frédéric Bernon
elessair 0:f269e3021894 3075 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
elessair 0:f269e3021894 3076 because current code doesn't follow rawapi.txt documentation.
elessair 0:f269e3021894 3077
elessair 0:f269e3021894 3078 2007-07-13 Kieran Mansley
elessair 0:f269e3021894 3079 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in

elessair 0:f269e3021894 3081
elessair 0:f269e3021894 3082 2007-07-03 Simon Goldschmidt
elessair 0:f269e3021894 3083 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
elessair 0:f269e3021894 3084 assumption is made that this pbuf is in one piece (i.e. not chained). These
elessair 0:f269e3021894 3085 assumptions clash with the possibility of converting to fully pool-based
elessair 0:f269e3021894 3086 pbuf implementations, where PBUF_RAM pbufs might be chained.

elessair 0:f269e3021894 3089 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
elessair 0:f269e3021894 3090 when closing tcp netconns: removed conn->sem, less context switches when
elessair 0:f269e3021894 3091 closing, both netconn_close and netconn_delete should safely close tcp
elessair 0:f269e3021894 3092 connections.

elessair 0:f269e3021894 3096 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
elessair 0:f269e3021894 3097 to cache ARP table indices with each pcb instead of single-entry cache for
elessair 0:f269e3021894 3098 the complete stack.

elessair 0:f269e3021894 3101 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent

elessair 0:f269e3021894 3107 2007-06-28 Simon Goldschmidt
elessair 0:f269e3021894 3108 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if

elessair 0:f269e3021894 3111 2007-06-28 Frédéric Bernon
elessair 0:f269e3021894 3112 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
elessair 0:f269e3021894 3113 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
elessair 0:f269e3021894 3114 possible to define this macro in your own lwipopts.h to always use C library's
elessair 0:f269e3021894 3115 rand(). Note that autoip_create_rand_addr doesn't use this macro.

elessair 0:f269e3021894 3118 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
elessair 0:f269e3021894 3119 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
elessair 0:f269e3021894 3120 in api_lib/api_msg (use pointers and not type with table, etc...)

elessair 0:f269e3021894 3167 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
elessair 0:f269e3021894 3168 re-used the input pbuf even if that didn't have enough space to include the
elessair 0:f269e3021894 3169 link headers. Now the space is tested and a new pbuf is allocated for the
elessair 0:f269e3021894 3170 echo response packet if the echo request pbuf isn't big enough.

elessair 0:f269e3021894 3175 2007-05-23 Frédéric Bernon
elessair 0:f269e3021894 3176 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
elessair 0:f269e3021894 3177 allocated by do_listen if success) and netconn_accept errors handling. In
elessair 0:f269e3021894 3178 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
elessair 0:f269e3021894 3179 by ASSERT, except for netconn_delete.

elessair 0:f269e3021894 3181 2007-05-23 Frédéric Bernon
elessair 0:f269e3021894 3182 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
elessair 0:f269e3021894 3183 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
elessair 0:f269e3021894 3184 directly close the recvmbox).

elessair 0:f269e3021894 3186 2007-05-22 Simon Goldschmidt
elessair 0:f269e3021894 3187 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
elessair 0:f269e3021894 3188 bound but unconnected (and non-listening) tcp_pcbs.
elessair 0:f269e3021894 3189
elessair 0:f269e3021894 3190 2007-05-22 Frédéric Bernon
elessair 0:f269e3021894 3191 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
elessair 0:f269e3021894 3192 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
elessair 0:f269e3021894 3193 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
elessair 0:f269e3021894 3194 like "sys_timeout" in their application threads.

elessair 0:f269e3021894 3197 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
elessair 0:f269e3021894 3198 which parameters are used by which do_xxx function, and to avoid "misusing"
elessair 0:f269e3021894 3199 parameters (patch #5938).

elessair 0:f269e3021894 3201 2007-05-22 Simon Goldschmidt
elessair 0:f269e3021894 3202 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
elessair 0:f269e3021894 3203 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
elessair 0:f269e3021894 3204 is only 8 bits wide. This affects the api, as there, the protocol was
elessair 0:f269e3021894 3205 u16_t, too.

elessair 0:f269e3021894 3208 * memp.c: addition to patch #5913: smaller pointer was returned but
elessair 0:f269e3021894 3209 memp_memory was the same size -> did not save memory.

elessair 0:f269e3021894 3215 2007-05-16 Simon Goldschmidt
elessair 0:f269e3021894 3216 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
elessair 0:f269e3021894 3217 as the one of the netif used for sending to prevent sending from old
elessair 0:f269e3021894 3218 addresses after a netif address gets changed (partly fixes bug #3168).

elessair 0:f269e3021894 3221 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
elessair 0:f269e3021894 3222 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
elessair 0:f269e3021894 3223 tcpip_init) because we have to be sure that network interfaces are already
elessair 0:f269e3021894 3224 added (mac filter is updated only in igmp_init for the moment).

elessair 0:f269e3021894 3227 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
elessair 0:f269e3021894 3228 into sys_arch_sem_wait calls to prevent timers from running while waiting
elessair 0:f269e3021894 3229 for the heap. This fixes bug #19167.

elessair 0:f269e3021894 3232 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines

elessair 0:f269e3021894 3240 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
elessair 0:f269e3021894 3241 implementation so that it can be reused (don't allocate the target
elessair 0:f269e3021894 3242 pbuf inside pbuf_copy()).

elessair 0:f269e3021894 3245 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
elessair 0:f269e3021894 3246 to save a little RAM (next pointer of memp is not used while not in pool).

elessair 0:f269e3021894 3252 2007-04-23 Simon Goldschmidt
elessair 0:f269e3021894 3253 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
elessair 0:f269e3021894 3254 in NULL reference for incoming TCP packets". Loopif has to be configured
elessair 0:f269e3021894 3255 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()

elessair 0:f269e3021894 3262 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
elessair 0:f269e3021894 3263 the difference between two u16_t's.
elessair 0:f269e3021894 3264 * sockets.h: FD_SETSIZE needs to match number of sockets, which is

elessair 0:f269e3021894 3306 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple

elessair 0:f269e3021894 3328 * ethernetif.c: update netif->input calls to check return value. In older ports,
elessair 0:f269e3021894 3329 it's a good idea to upgrade them, even if before, there could be another problem
elessair 0:f269e3021894 3330 (access to an uninitialized mailbox).

elessair 0:f269e3021894 3333 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed

elessair 0:f269e3021894 3340 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a

elessair 0:f269e3021894 3354 * Fix all uses of pbuf_header to check the return value. In some
elessair 0:f269e3021894 3355 cases just assert if it fails as I'm not sure how to fix them, but
elessair 0:f269e3021894 3356 this is no worse than before when they would carry on regardless

elessair 0:f269e3021894 3612 Halved the ARP period, doubled the period counts.
elessair 0:f269e3021894 3613 ETHARP_MAX_PENDING now should be at least 2. This prevents
elessair 0:f269e3021894 3614 the counter from reaching 0 right away (which would allow

elessair 0:f269e3021894 3620 Do not try hard to insert arbitrary packet's source address,
elessair 0:f269e3021894 3621 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
elessair 0:f269e3021894 3622 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
elessair 0:f269e3021894 3623 querying an address will see it appear in the cache (DHCP could
elessair 0:f269e3021894 3624 suffer from this when a server invalidly gave an in-use address.)
elessair 0:f269e3021894 3625 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
elessair 0:f269e3021894 3626 comparing network addresses (identifiers), not the network masks
elessair 0:f269e3021894 3627 themselves.
elessair 0:f269e3021894 3628 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given

elessair 0:f269e3021894 3638 even if one is already pending, if the rcv_wnd is above a threshold
elessair 0:f269e3021894 3639 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
elessair 0:f269e3021894 3640 delayed ACK in order to open the window if the stack is only receiving data.

elessair 0:f269e3021894 3652 * pbuf.c: Stopped compiler complaining of empty if statement

elessair 0:f269e3021894 3657 * inet.c: Added a couple of casts to quiet the compiler.
elessair 0:f269e3021894 3658 No need to test isascii(c) before isdigit(c) or isxdigit(c).

elessair 0:f269e3021894 3662 Added casts for return values of checksum routines, to pacify compiler.
elessair 0:f269e3021894 3663 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c

elessair 0:f269e3021894 3670 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
elessair 0:f269e3021894 3671 of raw_recv() in raw.h and so avoid compiler error.
elessair 0:f269e3021894 3672 * sockets.c: Added trivial (int) cast to keep compiler happier.
elessair 0:f269e3021894 3673 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.

elessair 0:f269e3021894 3681 your cc.h file defines this either 1 or 0. If non-defined,
elessair 0:f269e3021894 3682 defaults to 1.

elessair 0:f269e3021894 4074 * The API now has proper error handling. A new function,
elessair 0:f269e3021894 4075 netconn_err(), now returns an error code for the connection in
elessair 0:f269e3021894 4076 case of errors.
elessair 0:f269e3021894 4077
elessair 0:f269e3021894 4078 * Improvements in the memory management subsystem. The system now
elessair 0:f269e3021894 4079 keeps a pointer to the lowest free memory block. A new function,
elessair 0:f269e3021894 4080 mem_malloc2() tries to allocate memory once, and if it fails tries
elessair 0:f269e3021894 4081 to free some memory and retry the allocation.
elessair 0:f269e3021894 4082
elessair 0:f269e3021894 4083 * Much testing has been done with limited memory
elessair 0:f269e3021894 4084 configurations. lwIP now does a better job when overloaded.
elessair 0:f269e3021894 4085
elessair 0:f269e3021894 4086 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
elessair 0:f269e3021894 4087
elessair 0:f269e3021894 4088 * Many bugfixes in the TCP code:
elessair 0:f269e3021894 4089
elessair 0:f269e3021894 4090 - Fixed a bug in tcp_close().
elessair 0:f269e3021894 4091
elessair 0:f269e3021894 4092 - The TCP receive window was incorrectly closed when out of
elessair 0:f269e3021894 4093 sequence segments was received. This has been fixed.
elessair 0:f269e3021894 4094
elessair 0:f269e3021894 4095 - Connections are now timed-out of the FIN-WAIT-2 state.
elessair 0:f269e3021894 4096
elessair 0:f269e3021894 4097 - The initial congestion window could in some cases be too
elessair 0:f269e3021894 4098 large. This has been fixed.
elessair 0:f269e3021894 4099
elessair 0:f269e3021894 4100 - The retransmission queue could in some cases be screwed up. This
elessair 0:f269e3021894 4101 has been fixed.
elessair 0:f269e3021894 4102
elessair 0:f269e3021894 4103 - TCP RST flag now handled correctly.
elessair 0:f269e3021894 4104
elessair 0:f269e3021894 4105 - Out of sequence data was in some cases never delivered to the
elessair 0:f269e3021894 4106 application. This has been fixed.
elessair 0:f269e3021894 4107
elessair 0:f269e3021894 4108 - Retransmitted segments now contain the correct acknowledgment
elessair 0:f269e3021894 4109 number and advertised window.
elessair 0:f269e3021894 4110
elessair 0:f269e3021894 4111 - TCP retransmission timeout backoffs are not correctly computed
elessair 0:f269e3021894 4112 (ala BSD). After a number of retransmissions, TCP now gives up
elessair 0:f269e3021894 4113 the connection.
elessair 0:f269e3021894 4114
elessair 0:f269e3021894 4115 * TCP connections now are kept on three lists, one for active
elessair 0:f269e3021894 4116 connections, one for listening connections, and one for
elessair 0:f269e3021894 4117 connections that are in TIME-WAIT. This greatly speeds up the fast
elessair 0:f269e3021894 4118 timeout processing for sending delayed ACKs.
elessair 0:f269e3021894 4119
elessair 0:f269e3021894 4120 * TCP now provides proper feedback to the application when a
elessair 0:f269e3021894 4121 connection has been successfully set up.
elessair 0:f269e3021894 4122
elessair 0:f269e3021894 4123 * More comments have been added to the code. The code has also been
elessair 0:f269e3021894 4124 somewhat cleaned up.
elessair 0:f269e3021894 4125
elessair 0:f269e3021894 4126 (0.2) Initial public release.
