HISTORY
(CVS HEAD)
* [Enter new changes just after this line - do not remove this line]
++ New features:
2012-03-25: Simon Goldschmidt (idea by Mason)
* posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h
which are a simple wrapper to the correct lwIP include files.
2012-01-16: Simon Goldschmidt
* opt.h, icmp.c: Added option CHECKSUM_GEN_ICMP
2011-12-17: Simon Goldschmidt
* ip.h: implemented API functions to access so_options of IP pcbs (UDP, TCP, RAW)
(fixes bug #35061)
2011-09-27: Simon Goldschmidt
* opt.h, tcp.c, tcp_in.c: Implemented limiting data on ooseq queue (task #9989)
(define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h)
2011-09-21: Simon Goldschmidt
* opt.h, api.h, api_lib.c, api_msg.h/.c, sockets.c: Implemented timeout on
send (TCP only, bug #33820)
2011-09-21: Simon Goldschmidt
* init.c: Converted runtime-sanity-checks into compile-time checks that can
be disabled (since runtime checks can often not be seen on embedded targets)
2011-09-11: Simon Goldschmidt
* ppp.h, ppp_impl.h: splitted ppp.h to an internal and external header file
to get a clear separation of which functions an application or port may use
(task #11281)
2011-09-11: Simon Goldschmidt
* opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize
initial local TCP/UDP ports (so that different port ranges are used after
a reboot; bug #33818; this one added tcp_init/udp_init functions again)
2011-09-03: Simon Goldschmidt
* dhcp.c: DHCP uses LWIP_RAND() for xid's (bug #30302)
2011-08-24: Simon Goldschmidt
* opt.h, netif.h/.c: added netif remove callback (bug #32397)
2011-07-26: Simon Goldschmidt
* etharp.c: ETHARP_SUPPORT_VLAN: add support for an external VLAN filter
function instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
2011-07-21: Simon Goldschmidt (patch by hanhui)
* ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
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).
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.
2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)
* tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
pcb->state != LISTEN
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 :-)
2011-05-14: Simon Goldschmidt (patch by Stéphane Lesage)
* tcpip.c/.h: patch #7449 allow tcpip callback from interrupt with static
memory message

calculate it in tcp_zero_window_probe (the only place where it was used).
2010-11-21: Simon Goldschmidt
* dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
(fixes bug #31525).

IP_MULTICAST_LOOP at socket- and raw-API level.
2010-06-16: Simon Goldschmidt

link-layer-addressed UDP traffic to be received while a netif is down (just
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
* udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that

into a pbuf and at the same time calculating the checksum for that data
2010-04-29: Simon Goldschmidt
* ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
2-byte-aligned IP addresses and MAC addresses

fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
2010-03-27: Simon Goldschmidt

since the linker cannot do this automatically to save space.
2010-03-20: 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

* api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
blocking send operation)
2010-02-12: 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
netif.c) - loopif does not have to be created by the port any more,
just define LWIP_HAVE_LOOPIF to 1.
2010-02-08: Simon Goldschmidt
* inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
inet_ntoa_r/ipaddr_ntoa_r

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)

2010-01-27: Simon Goldschmidt
* opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding
to TCP_SNDLOWAT and added tcp_sndqueuelen() - this fixes bug #28605

2010-01-14: Simon Goldschmidt
* ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
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

2009-12-31: Simon Goldschmidt
* tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
added timers.c/.h: Separated timer implementation from semaphore/mbox
implementation, moved timer implementation to timers.c/.h, timers are
now only called from tcpip_thread or by explicitly checking them.
(TASK#7235)
2009-12-27: Simon Goldschmidt
* opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option

"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

2010-02-14: Simon Goldschmidt
* netif.c: Fixed bug #28877 (Duplicate ARP gratuitous packet with
LWIP_NETIF_LINK_CALLBACK set on) by only sending if both link- and
admin-status of a netif are up
2010-02-14: 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
* etharp.c/.h: Fixed ARP input processing: only add a new entry if a
request was directed as us (RFC 826, Packet Reception), otherwise
only update existing entries; internalized some functions
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
* netif.c: netif_set_link_up/down: only do something if the link state
actually changes
2010-02-12: Simon Goldschmidt/Stephane Lesage

(recv() makes receive window update for data that wasn't received by
application)
2010-02-09: Simon Goldschmidt/Stephane Lesage

for the loopback netif.
2010-02-08: Simon Goldschmidt
* igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
since they are not used anywhere else.
2010-02-08: Simon Goldschmidt (Stéphane Lesage)
* igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
(patch from bug #28798)
2010-02-08: Simon Goldschmidt (Stéphane Lesage)
* igmp.c: Fixed bug #28798 (Error in "Max Response Time" processing) and
another bug when LWIP_RAND() returns zero.
2010-02-04: Simon Goldschmidt
* nearly every file: Use macros defined in ip_addr.h (some of them new)
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,
ERR_ABRT means the application has called tcp_abort()!
2010-01-25: Simon Goldschmidt
* snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
not implemented in SNMP): write-only or not-accessible are still
returned by getnext (though not by get)
2010-01-24: Simon Goldschmidt
* snmp: Renamed the private mib node from 'private' to 'mib_private' to
not use reserved C/C++ keywords

2010-01-18: Simon Goldschmidt
* mem.c: Fixed bug #28679: mem_realloc calculates mem_stats wrong
2010-01-17: Simon Goldschmidt
* api_lib.c, api_msg.c, (api_msg.h, api.h, sockets.c, tcpip.c):
task #10102: "netconn: clean up conn->err threading issues" by adding
error return value to struct api_msg_msg
2010-01-17: Simon Goldschmidt
* api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()

2010-01-08: Simon Goldschmidt
