(git master)
* [Enter new changes just after this line - do not remove this line]
++ New features:
2015-01-02: Simon Goldschmidt
* tcp.c: tcp_kill_prio(): prefer nearly-closed connections (waiting for the
last ACK only) over established connections when out of tcp pcbs
2015-01-17: Simon Goldschmidt
* api: allow enabling socket API without (public) netconn API - netconn API is
still used by sockets, but keeping it private (static) should allow better
compiler optimizations
2015-01-16: Simon Goldschmidt
* tcp_in.c: fixed bug #20506 "Initial congestion window is very small" again
by implementing the calculation formula from RFC3390
2014-12-10: Simon Goldschmidt
* api: added option LWIP_NETCONN_SEM_PER_THREAD to use a semaphore per thread
instead of using one per netconn and per select call
2014-12-08: Simon Goldschmidt
* ip6.h: fixed bug #43778: IPv6 header version not set on 16-bit platform
(macro IP6H_VTCFL_SET())
2014-12-08: Simon Goldschmidt
* icmp.c, ip4.c, pbuf.c, udp.c, pbuf.h: task #11472 Support PBUF_REF for RX
(IPv6 and IPv4/v6 reassembly might not work yet)
2014-11-06: Simon Goldschmidt
* sockets.c/.h, init.c: lwip_socket_init() is not needed any more
-> compatibility define
2014-09-16: Simon Goldschmidt
* dns.c, opt.h: reduced ram usage by parsing DNS responses in place
2014-09-16: Simon Goldschmidt
* pbuf.h/.c: added pbuf_take_at() and pbuf_put_at()
2014-09-15: Simon Goldschmidt
* dns.c: added source port randomization to make the DNS client more robust
(see bug #43144)
2013-09-02: Simon Goldschmidt
* arch.h and many other files: added optional macros PACK_STRUCT_FLD_8() and
PACK_STRUCT_FLD_S() to prevent gcc 4 from warning about struct members that
do not need packing
2013-08-19: Simon Goldschmidt
* netif.h: bug #42998: made NETIF_MAX_HWADDR_LEN overridable for some special
networks
2013-03-17: Simon Goldschmidt (patch by Ghobad Emadi)
* opt.h, etharp.c: Added LWIP_HOOK_ETHARP_GET_GW to implement IPv4 routing with
multiple gateways
2013-04-20: Fatih Asici
* opt.h, etharp.h/.c: patch #7993: Added support for transmitting packets
with VLAN headers via hook function LWIP_HOOK_VLAN_SET and to check them
via hook function LWIP_HOOK_VLAN_CHECK
2014-02-20: Simon Goldschmidt (based on patch by Artem Pisarenko)
* patch #7885: modification of api modules to support FreeRTOS-MPU
(don't pass stack-pointers to other threads)
2014-02-05: Simon Goldschmidt (patch by "xtian" and "alex_ab")
* patch #6537/#7858: TCP window scaling support
2014-01-17: Jiri Engelthaler
* icmp, icmp6, opt.h: patch #8027: Completed HW checksuming for IPv4 and
IPv6 ICMP's
2012-08-22: Sylvain Rochet
* 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 ECP support using a macro, so that it can be ported later.
- Disabled CCP support using a macro, so that it can be ported later.
- Disabled CBCP support using a macro, so that it can be ported later.
- Disabled LQR support using a macro, so that it can be ported later.
- Print packet debug feature optional, through PRINTPKT_SUPPORT
- Removed POSIX signal usage.
- Fully ported PPPoS code from the previous port.
- Fully ported PPPoE code from the previous port.
- Fully ported VJ compression protocol code from the previous port.
- Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
- Disabled PPP server support using a macro, so that it can be ported later.
- Switched all PPP debug to lwIP debug system.
- Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
removed all global variables everywhere, did everything necessary for
the PPP stack to support more than one PPP session (pppd only support
one session per process).
- Removed the statically allocated output buffer, now using PBUF.
- Improved structure size of all PPP modules, deep analyze of code to reduce
variables size to the bare minimum. Switched all boolean type (char type in
most architecture) to compiler generated bitfields.
- Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
- Now using a persistent netif interface which can then be used in lwIP
functions requiring a netif.
- Now initializing PPP in lwip_init() function.
- Reworked completely the PPP state machine, so that we don't end up in
anymore in inconsistent state, especially with PPPoE.
- Improved the way we handle PPP reconnection after disconnect, cleaning
everything required so that we start the PPP connection again from a
clean state.
- Added PPP holdoff support, allow the lwIP user to wait a little bit before
reconnecting, prevents connection flood, especially when using PPPoL2TP.
- Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
feature to lwIP, L2TP being a widely used tunnel protocol.
- Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
- Added PPP API "sequential" thread-safe API, based from NETIFAPI.
2011-07-21: Simon Goldschmidt
* sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
ioctl/FIONREAD return the size of the next pending datagram.
2011-05-25: Simon Goldschmidt
* again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
code so that the code is more readable.
2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
* nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
Ivan! (this is work in progress: we're just post release anyway :-)

Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
Also added code to allow ip_forward() to forward non-broadcast packets to
the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).

always EMSGSIZE on non-blocking sockets if data size > send buffers) -> now
lwip_send() sends as much as possible for non-blocking sockets
2011-07-22: Simon Goldschmidt
* pbuf.c/.h, timers.c: freeing ooseq pbufs when the pbuf pool is empty implemented

2010-11-21: Simon Goldschmidt
* dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
(fixes bug #31525).

like DHCP during configuration)
2010-05-22: Simon Goldschmidt
* many many files: bug #27352: removed packing from ip_addr_t, the packed
version is now only used in protocol headers. Added global storage for
current src/dest IP address while in input functions.
2010-05-16: Simon Goldschmidt
* def.h: task #10391: Add preprocessor-macros for compile-time htonl
calculation (and use them throughout the stack where applicable)
2010-05-16: Simon Goldschmidt

instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
2010-05-16: Simon Goldschmidt
* opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
MEMP pool instead of the heap
2010-05-13: Simon Goldschmidt
* tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
packets to more than one pcb.
2010-05-02: Simon Goldschmidt
* netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
2010-04-30: Simon Goldschmidt

2010-03-14: Simon Goldschmidt
* tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
when creating TCP segments, not when (re-)transmitting them.
2010-03-07: Simon Goldschmidt
* sockets.c: bug #28775 (select/event_callback: only check select_cb_list
on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
This should speed up receiving data on sockets as the select code in
event_callback is only executed when select is waiting.
2010-03-06: Simon Goldschmidt
* tcp_out.c: task #7013 (Create option to have all packets delivered to
netif->output in one piece): Always copy to try to create single pbufs
in tcp_write.
2010-03-06: Simon Goldschmidt
* api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv

for tcp sockets.
2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
* opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
Work on tcp_enqueue: Don't waste memory when chaining segments,
added option TCP_OVERSIZE to prevent creating many small pbufs when
calling tcp_write with many small blocks of data. Instead, pbufs are
allocated larger than needed and the space is used for later calls to
tcp_write.
2010-02-21: Simon Goldschmidt
* stats.c/.h: Added const char* name to mem- and memp-stats for easier
debugging.
2010-02-21: Simon Goldschmidt

standardised way to set O_NONBLOCK for nonblocking sockets.
2010-02-12: Simon Goldschmidt
* dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
and dhcp work with user-allocated structs instead of callin mem_malloc
2010-02-12: Simon Goldschmidt/Jeff Barber
* tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
2010-02-12: Simon Goldschmidt
* sys layer: task #10139 (Prefer statically allocated memory): converted
mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
to let sys.h use binary semaphores instead of mutexes - as before)
2010-02-09: Simon Goldschmidt (Simon Kallweit)
* timers.c/.h: Added function sys_restart_timeouts() from patch #7085
(Restart system timeout handling)
2010-02-09: Simon Goldschmidt
* netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into

2010-02-05: Simon Goldschmidt
* netif.h: Added function-like macros to get/set the hostname on a netif
2010-02-04: Simon Goldschmidt
* nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
make changing the actual implementation behind the typedef easier.
2010-02-01: Simon Goldschmidt
* opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
for allocating memory when getaddrinfo() is called.
2010-01-31: Simon Goldschmidt
* dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
them once instead of parsing for every option. This also removes
the need for mem_malloc from dhcp_recv and makes it possible to
correctly retrieve the BOOTP file.
2010-01-30: simon Goldschmidt
* sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
the sockets array.
2010-01-29: Simon Goldschmidt (patch by Laura Garrett)

by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
2010-01-13: Simon Goldschmidt
* mem.c: The heap now may be moved to user-defined memory by defining

calling sio_read_abort() if the file descriptor is valid.
2011-03-14: Simon Goldschmidt
* err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect

"FATAL" classification of error codes: ERR_USE and ERR_ISCONN just aren't fatal.
2011-03-13: Simon Goldschmidt
* sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing
err_to_errno_table (ERR_CLSD: ENOTCONN instead of ESHUTDOWN), ERR_ISCONN:
use EALRADY instead of -1
2011-03-13: Simon Goldschmidt
* api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the

and basing PBUF_LINK_HLEN on it.
2010-03-08: Simon Goldschmidt

* opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
reception and is not really necessary
2010-02-14: Simon Goldschmidt

request was directed as us (RFC 826, Packet Reception), otherwise

2010-02-14: Simon Goldschmidt
* netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
disabled on netif used for PPPoE) by adding a new netif flag
(NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
device but prevents usage of ARP (so that ethernet_input can be used
for PPPoE).
2010-02-12: Simon Goldschmidt

(patch from bug #28798)

another bug when LWIP_RAND() returns zero.
2010-02-04: Simon Goldschmidt

to work with IP addresses (preparation for bug #27352 - Change ip_addr
from struct to typedef (u32_t) - and better code).
2010-01-31: Simon Goldschmidt
* netif.c: Don't call the link-callback from netif_set_up/down() since
this invalidly retriggers DHCP.
2010-01-29: Simon Goldschmidt
* ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
portability file inet.h and its contents from the stack: moved htonX-
functions to def.h (and the new def.c - they are not ipv4 dependent),
let inet.h depend on ip_addr.h and not the other way round.
This fixes bug #28732.
2010-01-28: Kieran Mansley
* tcp.c: Ensure ssthresh >= 2*MSS
2010-01-27: Simon Goldschmidt
* tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
callback can lead to accessing unallocated memory. As a consequence,

which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
If you want this option also filter broadcast on recv operations, you also
have to set IP_SOF_BROADCAST_RECV=1 in opt.h.

(STABLE-1.3.0)
++ New features:
2008-03-10 Jonathan Larmour
* inet_chksum.c: Allow choice of one of the sample algorithms to be

2008-01-22 Fr<46>d<EFBFBD>ric Bernon
* tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in

2008-01-14 Fr<46>d<EFBFBD>ric Bernon
* rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
tcp_recv callback (see rawapi.txt).
2008-01-14 Fr<46>d<EFBFBD>ric Bernon, Marc Chaland
* ip.c: Integrate patch #6369" ip_input : checking before realloc".
2008-01-12 Fr<46>d<EFBFBD>ric Bernon
* tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
netconn::sem per netconn::op_completed like suggested for the task #7490
"Add return value to sys_mbox_post".
2008-01-12 Fr<46>d<EFBFBD>ric Bernon
* api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
2008-01-10 Fr<46>d<EFBFBD>ric Bernon
* tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
"Add return value to sys_mbox_post". tcpip_callback is always defined as
"blocking" ("block" parameter = 1).
2008-01-10 Fr<46>d<EFBFBD>ric Bernon
* tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
"Add return value to sys_mbox_post".
2008-01-05 Fr<46>d<EFBFBD>ric Bernon
* sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
indicate the number of pointers query by the mailbox. There is three defines
in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
netconn::acceptmbox. Port maintainers, you can decide to just add this new
parameter in your implementation, but to ignore it to keep the previous behavior.
The new sys_mbox_trypost function return a value to know if the mailbox is
full or if the message is posted. Take a look to sys_arch.txt for more details.
This new function is used in tcpip_input (so, can be called in an interrupt
context since the function is not blocking), and in recv_udp and recv_raw.
2008-01-04 Fr<46>d<EFBFBD>ric Bernon, Simon Goldschmidt, Jonathan Larmour
* rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
"backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
documentation in the rawapi.txt file.
2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
* tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
2007-12-31 Fr<46>d<EFBFBD>ric Bernon, Luca Ceresoli
* autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
in autoip". The change in etharp_raw could be removed, since all calls to
etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
wrong in the future.
2007-12-30 Fr<46>d<EFBFBD>ric Bernon, Tom Evans
* ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
Filtering" reported by Tom Evans.
2007-12-21 Fr<46>d<EFBFBD>ric Bernon, Simon Goldschmidt, Jonathan Larmour
* tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
applications have to call 'tcp_accepted(pcb)' in their accept callback to
keep accepting new connections.
2007-12-13 Fr<46>d<EFBFBD>ric Bernon
* api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
by err_t type. Add a new err_t code "ERR_INPROGRESS".
2007-12-12 Fr<46>d<EFBFBD>ric Bernon
* dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
are the one which have ram usage.
2007-12-05 Fr<46>d<EFBFBD>ric Bernon
* netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
set of variables (=0) or a local one (=1). In this last case, your port should
provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
2007-12-03 Simon Goldschmidt
* ip.c: ip_input: check if a packet is for inp first before checking all other
netifs on netif_list (speeds up packet receiving in most cases)
2007-11-30 Simon Goldschmidt
* udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
UDP: move a (connected) pcb selected for input to the front of the list of
pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
a packet.
2007-11-28 Simon Goldschmidt
* etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
2007-11-25 Simon Goldschmidt
* dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
algorithm.
2007-11-24 Simon Goldschmidt
* netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
to the new file netdb.c; included lwip_getaddrinfo.
2007-11-21 Simon Goldschmidt
* tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
based on the MTU of the netif used to send. Enabled by default. Disable by
setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
2007-11-19 Fr<46>d<EFBFBD>ric Bernon
* api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
received match the name query), implement DNS_USES_STATIC_BUF (the place where
copy dns payload to parse the response), return an error if there is no place
for a new query, and fix some minor problems.
2007-11-16 Simon Goldschmidt
* new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
removed files: core/inet.c, core/inet6.c
Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
inet and chksum part; changed includes in all lwIP files as appropriate
2007-11-16 Simon Goldschmidt
* api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
dns resolver function for netconn api (netconn_gethostbyname) and socket api
(gethostbyname/gethostbyname_r).
2007-11-15 Jim Pettinato, Fr<46>d<EFBFBD>ric Bernon
* opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
requests with RAW api interface. Initialization is done in lwip_init() with
build time options. DNS timer is added in tcpip_thread context. DHCP can set
DNS server ip addresses when options are received. You need to set LWIP_DNS=1
in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
list with points to improve.
2007-11-06 Simon Goldschmidt
* opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
2007-11-06 Simon Goldschmidt
* api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
implementation from netconn api applications.
2007-11-03 Fr<46>d<EFBFBD>ric Bernon
* api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
by default). Netconn API users can use the netconn_recv_bufsize macro to access
it. This is a first release which have to be improve for TCP. Note it used the
netconn::recv_avail which need to be more "thread-safe" (note there is already
the problem for FIONREAD with lwip_ioctl/ioctlsocket).
2007-11-01 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
some code (like we have talk in "patch #5919 : Create compile switch to remove
select code"), but it could be done later.
2007-10-08 Simon Goldschmidt
* many files: Changed initialization: many init functions are not needed any
more since we now rely on the compiler initializing global and static
variables to zero!
2007-10-06 Simon Goldschmidt
* ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
to enqueue the received pbufs so that multiple packets can be reassembled
simultaneously and no static reassembly buffer is needed.
2007-10-05 Simon Goldschmidt
* tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
all netifs (or ports) can use it.
2007-10-05 Fr<46>d<EFBFBD>ric Bernon
* netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
common function to reduce a little bit the footprint (for all functions using
only the "netif" parameter).
2007-10-03 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon, Jonathan Larmour
* init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
user-configurable values".
2007-08-29 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
connections, such present in patch #5959.
2007-05-23 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 <sys/time.h> 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
and fix some coding style.
2007-08-28 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
all error cases.
2007-07-13 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 <errno.h>" 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
2007-03-22 Fr<46>d<EFBFBD>ric Bernon
* api_lib.c: somes resources couldn't be freed if there was errors during
netconn_new_with_proto_and_callback.
2007-03-22 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
2007-03-21 Fr<46>d<EFBFBD>ric 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 Fr<46>d<EFBFBD>ric Bernon
* memp.h, stats.c: Fix stats_display function where memp_names table wasn't
synchronized with memp.h.
2007-03-20 Fr<46>d<EFBFBD>ric 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. Also fix a compiler warning.
2007-03-20 Kieran Mansley
* udp.c: Only try and use pbuf_header() to make space for headers if
not a ROM or REF pbuf.
2007-03-19 Fr<46>d<EFBFBD>ric Bernon
* api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
and api_msg_post().
2007-03-19 Fr<46>d<EFBFBD>ric Bernon
* Remove unimplemented "memp_realloc" function from memp.h.
2007-03-11 Simon Goldschmidt
* pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
memory corruption.
2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
* api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
(missing `const' qualifier in socket functions), to get more compatible to
standard POSIX sockets.
2007-03-11 Fr<46>d<EFBFBD>ric Bernon (based on patch from Dmitry Potapov)
* sockets.c: Add asserts inside bind, connect and sendto to check input
parameters. Remove excessive set_errno() calls after get_socket(), because
errno is set inside of get_socket(). Move last sock_set_errno() inside
lwip_close.
2007-03-09 Simon Goldschmidt
* memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
was allocated too small.
2007-03-06 Simon Goldschmidt
* tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
the stack from concurrent access.
2007-03-06 Fr<46>d<EFBFBD>ric Bernon, Dmitry Potapov
* tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2007-03-06 Simon Goldschmidt
* ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
if IP_FRAG == 0 and IP_REASSEMBLY == 0
2007-03-06 Fr<46>d<EFBFBD>ric Bernon, Simon Goldschmidt
* opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
Allow to do ARP processing for incoming packets inside tcpip_thread
(protecting ARP layer against concurrent access). You can also disable
old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
Older ports have to use tcpip_ethinput.
2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
* err.h, err.c: fixed compiler warning "initialization dircards qualifiers
from pointer target type"
2007-03-05 Fr<46>d<EFBFBD>ric Bernon
* opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
ETHARP_TRUST_IP_MAC, review SO_REUSE)
2007-03-04 Fr<46>d<EFBFBD>ric Bernon
* api_msg.c: Remove some compiler warnings : parameter "pcb" was never
referenced.
2007-03-04 Fr<46>d<EFBFBD>ric Bernon
* api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
Dmitry Potapov).
The api_msg struct stay on the stack (not moved to netconn struct).
2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
* pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
Also fixed cast warning in pbuf_alloc()
2007-03-04 Simon Goldschmidt
* etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2007-03-03 Fr<46>d<EFBFBD>ric Bernon
* udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
It is static, and never used in udp.c except udp_init().
2007-03-02 Simon Goldschmidt
* tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
tcpip_thread() to tcpip_init(). This way, raw API connections can be
initialized before tcpip_thread is running (e.g. before OS is started)
2007-03-02 Fr<46>d<EFBFBD>ric Bernon
* rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
interval.
2007-02-28 Kieran Mansley
* pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
outside the region of the pbuf by pbuf_header()
2007-02-28 Kieran Mansley
* sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
when supplied timeout is also non-zero
(STABLE-1.2.0)
2006-12-05 Leon Woestenberg
* CHANGELOG: Mention STABLE-1.2.0 release.
++ New features:
2006-12-01 Christiaan Simons
* mem.h, opt.h: Added MEM_LIBC_MALLOC option.
Note this is a workaround. Currently I have no other options left.
2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
* ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
to include/lwip/opt.h.
* ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
* opt.h: Add above new options.
2006-08-18 Christiaan Simons
* tcp_{in,out}.c: added SNMP counters.
* ipv4/ip.c: added SNMP counters.
* ipv4/ip_frag.c: added SNMP counters.
2006-08-08 Christiaan Simons
* etharp.{c,h}: added etharp_find_addr() to read
(stable) ethernet/IP address pair from ARP table

2006-06-27 Christiaan Simons
* api_msg.c: Applied patch for cold case (bug #11135).
In accept_function() ensure newconn->callback is always initialized.
2006-06-15 Christiaan Simons
* mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
facilitate printing of mem_size_t and u16_t statistics.
2006-06-14 Christiaan Simons
* api_msg.c: Applied patch #5146 to handle allocation failures
in accept() by Kevin Lawson.
2006-05-26 Christiaan Simons

from netconn_write() and added sys_sem_new to netconn_new_*.
(STABLE-1_1_1)
2006-03-03 Christiaan Simons
* ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
access and added pbuf_alloc() return value checks.
2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
* tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
now handled by the checksum routine properly.
2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
* pbuf.c: Fix alignment; pbuf_init() would not work unless
pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
* tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
submitted by Mitrani Hiroshi.
2005-12-15 Christiaan Simons
* inet.c: Disabled the added summing routine to preserve code space.
2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
* tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
Added Curt McDowell's optimized checksumming routine for future
inclusion. Need to create test case for unaliged, aligned, odd,
even length combination of cases on various endianess machines.
2005-12-09 Christiaan Simons
* inet.c: Rewrote standard checksum routine in proper portable C.
2005-11-25 Christiaan Simons
* udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
* *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
u32_t, s32_t typedefs. This solves most debug word-length assumes.
2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
* inet.c: Fixed unaligned 16-bit access in the standard checksum
routine by Peter Jolasson.
* slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
* tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
* tcp_{out|in}.c: Applied patch fixing unaligned access.
2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
* pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
* udp.c: UDP pcb->recv() was called even when it was NULL.
(STABLE-1_1_0)
2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
* etharp.*: Disabled multiple packets on the ARP queue.
This clashes with TCP queueing.
2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
* etharp.*: Fixed race condition from ARP request to ARP timeout.
Halved the ARP period, doubled the period counts.
ETHARP_MAX_PENDING now should be at least 2. This prevents
the counter from reaching 0 right away (which would allow
too little time for ARP responses to be received).
2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
* dhcp.c: Decline messages were not multicast but unicast.
* etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
Do not try hard to insert arbitrary packet's source address,
etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
etharp_query() now always DOES call ETHARP_TRY_HARD so that users
querying an address will see it appear in the cache (DHCP could
suffer from this when a server invalidly gave an in-use address.)
* ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
comparing network addresses (identifiers), not the network masks
themselves.
* ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
IP address actually belongs to the network of the given interface.
2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
* tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
(STABLE-1_1_0-RC1)
2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
* tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
even if one is already pending, if the rcv_wnd is above a threshold
(currently TCP_WND/2). This avoids waiting for a timer to expire to send a
delayed ACK in order to open the window if the stack is only receiving data.
2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
* tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2004-08-20 Tony Mountifield <tony@softins.co.uk>
* etharp.c: Make sure the first pbuf queued on an ARP entry
is properly ref counted.
2004-07-27 Tony Mountifield <tony@softins.co.uk>
* debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
warnings about comparison.
* pbuf.c: Stopped compiler complaining of empty if statement
when LWIP_DEBUGF() empty. Closed an unclosed comment.
* tcp.c: Stopped compiler complaining of empty if statement
when LWIP_DEBUGF() empty.
* ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
* inet.c: Added a couple of casts to quiet the compiler.
No need to test isascii(c) before isdigit(c) or isxdigit(c).
2004-07-22 Tony Mountifield <tony@softins.co.uk>
* inet.c: Made data types consistent in inet_ntoa().
Added casts for return values of checksum routines, to pacify compiler.
* ip_frag.c, tcp_out.c, sockets.c, pbuf.c
Small corrections to some debugging statements, to pacify compiler.
2004-07-21 Tony Mountifield <tony@softins.co.uk>
* etharp.c: Removed spurious semicolon and added missing end-of-comment.
* ethernetif.c Updated low_level_output() to match prototype for
netif->linkoutput and changed low_level_input() similarly for consistency.
* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
of raw_recv() in raw.h and so avoid compiler error.
* sockets.c: Added trivial (int) cast to keep compiler happier.
* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
(STABLE-1_0_0)
++ Changes:
2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
* sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
your cc.h file defines this either 1 or 0. If non-defined,
defaults to 1.
* .c: Added <string.h> and <errno.h> includes where used.
* etharp.c: Made some array indices unsigned.
2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
* netif.*: Added netif_set_up()/down().
* dhcp.c: Changes to restart program flow.
2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
* etharp.c: In find_entry(), instead of a list traversal per candidate, do a
single-pass lookup for different candidates. Should exploit locality.
2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
* 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 <leon.woestenberg@gmx.net>
* 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 <leon.woestenberg@gmx.net>
* 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. Fixed the case where the packets destination
address is already known; we now always queue the packet and perform an ARP
request.
(STABLE-0_7_0)
++ Bug fixes:
* Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
* Fixed TCP bug in dequeueing of FIN from out of order segment queue.
* Fixed two possible NULL references in rare cases.
(STABLE-0_6_6)
++ Bug fixes:
* Fixed DHCP which did not include the IP address in DECLINE messages.
++ Changes:
* etharp.c has been hauled over a bit.
(STABLE-0_6_5)
++ Bug fixes:
* Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
* Packets sent from ARP queue had invalid source hardware address.
++ Changes:
* Pass-by ARP requests do now update the cache.
++ New features:
* No longer dependent on ctype.h.
* New socket options.
* Raw IP pcb support.
(STABLE-0_6_4)
++ Bug fixes:
* Some debug formatters and casts fixed.
* Numereous fixes in PPP.
++ Changes:
* DEBUGF now is LWIP_DEBUGF
* pbuf_dechain() has been re-enabled.
* Mentioned the changed use of CVS branches in README.
(STABLE-0_6_3)
++ Bug fixes:
* Fixed pool pbuf memory leak in pbuf_alloc().
Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
Reported by Savin Zlobec.
* PBUF_POOL chains had their tot_len field not set for non-first
pbufs. Fixed in pbuf_alloc().
++ New features:
* Added PPP stack contributed by Marc Boucher
++ Changes:
* Now drops short packets for ICMP/UDP/TCP protocols. More robust.
* ARP queueuing now queues the latest packet instead of the first.
This is the RFC recommended behaviour, but can be overridden in
lwipopts.h.
(0.6.2)
++ Bugfixes:
* TCP has been fixed to deal with the new use of the pbuf->ref
counter.
* DHCP dhcp_inform() crash bug fixed.
++ Changes:
* Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
pbuf_refresh(). This has sped up pbuf pool operations considerably.
Implemented by David Haas.
(0.6.1)
++ New features:
* The packet buffer implementation has been enhanced to support
zero-copy and copy-on-demand for packet buffers which have their
payloads in application-managed memory.
Implemented by David Haas.
Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
if an outgoing packet can be directly sent on the link, or perform
a copy-on-demand when necessary.
The application can safely assume the packet is sent, and the RAM
is available to the application directly after calling udp_send()
or similar function.
++ Bugfixes:
* ARP_QUEUEING should now correctly work for all cases, including
PBUF_REF.
Implemented by Leon Woestenberg.
++ Changes:
* IP_ADDR_ANY is no longer a NULL pointer. 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 changes are
logged in CVS but have not been explained here.
(0.5.3) Changes since version 0.5.2
++ Bugfixes:
* memp_malloc(MEMP_API_MSG) could fail with multiple application
threads because it wasn't protected by semaphores.
++ Other changes:
* struct ip_addr now packed.
* The name of the time variable in arp.c has been changed to ctime
to avoid conflicts with the time() function.
(0.5.2) Changes since version 0.5.1
++ New features:
* A new TCP function, tcp_tmr(), now handles both TCP timers.
++ Bugfixes:
* A bug in tcp_parseopt() could cause the stack to hang because of a
malformed TCP option.
* The address of new connections in the accept() function in the BSD
socket library was not handled correctly.
* pbuf_dechain() did not update the ->tot_len field of the tail.
* Aborted TCP connections were not handled correctly in all
situations.
++ Other changes:
* All protocol header structs are now packed.
* The ->len field in the tcp_seg structure now counts the actual
amount of data, and does not add one for SYN and FIN segments.
(0.5.1) Changes since version 0.5.0
++ New features:
* Possible to run as a user process under Linux.
* Preliminary support for cross platform packed structs.
* ARP timer now implemented.
++ Bugfixes:
* TCP output queue length was badly initialized when opening
connections.
* TCP delayed ACKs were not sent correctly.
* Explicit initialization of BSS segment variables.
* read() in BSD socket library could drop data.
* Problems with memory alignment.
* Situations when all TCP buffers were used could lead to
starvation.
* TCP MSS option wasn't parsed correctly.
* Problems with UDP checksum calculation.
* IP multicast address tests had endianess problems.
* ARP requests had wrong destination hardware address.
++ Other changes:
* struct eth_addr changed from u16_t[3] array to u8_t[6].
* A ->linkoutput() member was added to struct netif.
* TCP and UDP ->dest_* struct members where changed to ->remote_*.
* ntoh* macros are now null definitions for big endian CPUs.
(0.5.0) Changes since version 0.4.2
++ New features:
* Redesigned operating system emulation layer to make porting easier.
* Better control over TCP output buffers.
* Documenation added.
++ Bugfixes:
* Locking issues in buffer management.
* Bugfixes in the sequential API.
* IP forwarding could cause memory leakage. This has been fixed.
++ Other changes:
* Directory structure somewhat changed; the core/ tree has been
collapsed.
(0.4.2) Changes since version 0.4.1
++ New features:
* Experimental ARP implementation added.
* Skeleton Ethernet driver added.
* Experimental BSD socket API library added.
++ Bugfixes:
* In very intense situations, memory leakage could occur. This has
been fixed.
++ Other changes:
* Variables named "data" and "code" have been renamed in order to
avoid name conflicts in certain compilers.
* Variable++ have in appliciable cases been translated to ++variable
since some compilers generate better code in the latter case.
(0.4.1) Changes since version 0.4
++ New features:
* TCP: Connection attempts time out earlier than data
transmissions. Nagle algorithm implemented. Push flag set on the
last segment in a burst.
* UDP: experimental support for UDP-Lite extensions.
++ Bugfixes:
* TCP: out of order segments were in some cases handled incorrectly,
and this has now been fixed. Delayed acknowledgements was broken
in 0.4, has now been fixed. Binding to an address that is in use
now results in an error. Reset connections sometimes hung an
application; this has been fixed.
* Checksum calculation sometimes failed for chained pbufs with odd
lengths. This has been fixed.
* API: a lot of bug fixes in the API. The UDP API has been improved
and tested. Error reporting and handling has been
improved. Logical flaws and race conditions for incoming TCP
connections has been found and removed.
* Memory manager: alignment issues. Reallocating memory sometimes
failed, this has been fixed.
* Generic library: bcopy was flawed and has been fixed.
++ Other changes:
* API: all datatypes has been changed from generic ones such as
ints, to specified ones such as u16_t. Functions that return
errors now have the correct type (err_t).
* General: A lot of code cleaned up and debugging code removed. Many
portability issues have been fixed.
* The license was changed; the advertising clause was removed.
* C64 port added.
* Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
fixing bugs!
(0.4) Changes since version 0.3.1
* Memory management has been radically changed; instead of
allocating memory from a shared heap, memory for objects that are
rapidly allocated and deallocated is now kept in pools. Allocation
and deallocation from those memory pools is very fast. The shared
heap is still present but is used less frequently.
* The memory, memory pool, and packet buffer subsystems now support
4-, 2-, or 1-byte alignment.
* "Out of memory" situations are handled in a more robust way.
* Stack usage has been reduced.
* Easier configuration of lwIP parameters such as memory usage,
TTLs, statistics gathering, etc. All configuration parameters are
now kept in a single header file "lwipopts.h".
* The directory structure has been changed slightly so that all
architecture specific files are kept under the src/arch
hierarchy.
* Error propagation has been improved, both in the protocol modules
and in the API.
* The code for the RTXC architecture has been implemented, tested
and put to use.
* Bugs have been found and corrected in the TCP, UDP, IP, API, and
the Internet checksum modules.
* Bugs related to porting between a 32-bit and a 16-bit architecture
have been found and corrected.
* The license has been changed slightly to conform more with the
original BSD license, including the advertisement clause.
(0.3.1) Changes since version 0.3
* Fix of a fatal bug in the buffer management. Pbufs with allocated
RAM never returned the RAM when the pbuf was deallocated.
* TCP congestion control, window updates and retransmissions did not
work correctly. This has now been fixed.
* Bugfixes in the API.
(0.3) Changes since version 0.2
* New and improved directory structure. 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.
- Connections are now timed-out of the FIN-WAIT-2 state.
- The initial congestion window could in some cases be too
large. This has been fixed.
- The retransmission queue could in some cases be screwed up. This
has been fixed.
- TCP RST flag now handled correctly.
- Out of sequence data was in some cases never delivered to the
application. 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.
