-
- ++ 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)

- 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)
-

- * 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 :-)

- tcp_write.
-
- 2010-02-21: Simon Goldschmidt

- 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

-
- 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)
-

- 2010-01-29: 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.
-

- * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
- from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
- in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
- or heap memory from interrupt context
-
- 2008-03-26 Simon Goldschmidt
- * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
- host sent a zero mss as TCP option.
-
-
-(STABLE-1.3.0)
-
- ++ New features:
-
- 2008-03-10 Jonathan Larmour
- * inet_chksum.c: Allow choice of one of the sample algorithms to be
- made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
-
- 2008-01-22 Frédéric Bernon
- * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
- TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
-
- 2008-01-14 Frédéric 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 Frédéric Bernon, Marc Chaland
- * ip.c: Integrate patch #6369" ip_input : checking before realloc".
-
- 2008-01-12 Frédéric Bernon
- * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
- netconn::sem per netconn::op_completed like suggested for the task #7490
- "Add return value to sys_mbox_post".
-
- 2008-01-12 Frédéric Bernon
- * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
- DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
- sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
-
- 2008-01-10 Frédéric Bernon
- * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
- "Add return value to sys_mbox_post". tcpip_callback is always defined as
- "blocking" ("block" parameter = 1).
-
- 2008-01-10 Frédéric Bernon
- * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
- netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
- "Add return value to sys_mbox_post".
-
- 2008-01-05 Frédéric Bernon
- * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
- Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
- modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
- indicate the number of pointers query by the mailbox. There is three defines
- in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
- netconn::acceptmbox. Port maintainers, you can decide to just add this new
- parameter in your implementation, but to ignore it to keep the previous behavior.
- The new sys_mbox_trypost function return a value to know if the mailbox is
- full or if the message is posted. Take a look to sys_arch.txt for more details.
- This new function is used in tcpip_input (so, can be called in an interrupt
- context since the function is not blocking), and in recv_udp and recv_raw.
-
- 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
- * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
- tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
- "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
- documentation in the rawapi.txt file.
-
- 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
- * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
-
- 2007-12-31 Frédéric Bernon, Luca Ceresoli
- * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
- in autoip". The change in etharp_raw could be removed, since all calls to
- etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
- wrong in the future.
-
- 2007-12-30 Frédéric Bernon, Tom Evans
- * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
- Filtering" reported by Tom Evans.
-
- 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
- * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
- sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
- applications have to call 'tcp_accepted(pcb)' in their accept callback to
- keep accepting new connections.
-
- 2007-12-13 Frédéric Bernon
- * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
- by err_t type. Add a new err_t code "ERR_INPROGRESS".
-
- 2007-12-12 Frédéric Bernon
- * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
- are the one which have ram usage.
-
- 2007-12-05 Frédéric Bernon
- * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
- set of variables (=0) or a local one (=1). In this last case, your port should
- provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
- which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
-
- 2007-12-03 Simon Goldschmidt
- * ip.c: ip_input: check if a packet is for inp first before checking all other
- netifs on netif_list (speeds up packet receiving in most cases)
-
- 2007-11-30 Simon Goldschmidt
- * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
- UDP: move a (connected) pcb selected for input to the front of the list of
- pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
- a packet.
-
- 2007-11-28 Simon Goldschmidt
- * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
-
- 2007-11-25 Simon Goldschmidt
- * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
- algorithm.
-
- 2007-11-24 Simon Goldschmidt
- * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
- to the new file netdb.c; included lwip_getaddrinfo.
-
- 2007-11-21 Simon Goldschmidt
- * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
- based on the MTU of the netif used to send. Enabled by default. Disable by
- setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
-
- 2007-11-19 Frédéric Bernon
- * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
- received match the name query), implement DNS_USES_STATIC_BUF (the place where
- copy dns payload to parse the response), return an error if there is no place
- for a new query, and fix some minor problems.
-
- 2007-11-16 Simon Goldschmidt
- * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
- removed files: core/inet.c, core/inet6.c
- Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
- inet and chksum part; changed includes in all lwIP files as appropriate
-
- 2007-11-16 Simon Goldschmidt
- * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
- dns resolver function for netconn api (netconn_gethostbyname) and socket api
- (gethostbyname/gethostbyname_r).
-
- 2007-11-15 Jim Pettinato, Frédéric Bernon
- * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
- requests with RAW api interface. Initialization is done in lwip_init() with
- build time options. DNS timer is added in tcpip_thread context. DHCP can set
- DNS server ip addresses when options are received. You need to set LWIP_DNS=1
- in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
- some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
- list with points to improve.
-
- 2007-11-06 Simon Goldschmidt
- * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
- enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
- for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
-
- 2007-11-06 Simon Goldschmidt
- * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
- core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
- implementation from netconn api applications.
-
- 2007-11-03 Frédéric Bernon
- * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
- RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
- by default). Netconn API users can use the netconn_recv_bufsize macro to access
- it. This is a first release which have to be improve for TCP. Note it used the
- netconn::recv_avail which need to be more "thread-safe" (note there is already
- the problem for FIONREAD with lwip_ioctl/ioctlsocket).
-
- 2007-11-01 Frédéric Bernon, Marc Chaland
- * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
- Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
- layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
- layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
- Note that previous "copy" parameter for "write" APIs is now called "apiflags".
-
- 2007-10-24 Frédéric Bernon
- * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
- TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
- some code (like we have talk in "patch #5919 : Create compile switch to remove
- select code"), but it could be done later.
-
- 2007-10-08 Simon Goldschmidt
- * many files: Changed initialization: many init functions are not needed any
- more since we now rely on the compiler initializing global and static
- variables to zero!
-
- 2007-10-06 Simon Goldschmidt
- * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
- to enqueue the received pbufs so that multiple packets can be reassembled
- simultaneously and no static reassembly buffer is needed.
-
- 2007-10-05 Simon Goldschmidt
- * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
- all netifs (or ports) can use it.
-
- 2007-10-05 Frédéric Bernon
- * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
- common function to reduce a little bit the footprint (for all functions using
- only the "netif" parameter).
-
- 2007-10-03 Frédéric Bernon
- * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
- netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
- a little bit the footprint (for all functions using only the "netif" parameter).
-
- 2007-09-15 Frédéric Bernon
- * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
- option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
- netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
- IP_MULTICAST_TTL and IP_MULTICAST_IF.
-
- 2007-09-10 Frédéric Bernon
- * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
- even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
- each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
- decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
- call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
- or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
- This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
- snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
- when it's queried (any direct call to "sysuptime" is changed by a call to
- snmp_get_sysuptime).
-
- 2007-09-09 Frédéric Bernon, Bill Florac
- * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
- and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
- if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
- igmp_report_groups() is now called inside netif_set_link_up() (need to have
- LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
- the next query message to receive the matching multicast streams).
-
- 2007-09-08 Frédéric Bernon
- * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
- IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
- Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
- Enable to access to these fields with LWIP_TCP=0.
-
- 2007-09-05 Frédéric Bernon
- * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
- ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
- LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
- Be careful, disabling ICMP make your product non-compliant to RFC1122, but
- help to reduce footprint, and to reduce "visibility" on the Internet.
-
- 2007-09-05 Frédéric Bernon, Bill Florac
- * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
- for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
- parameters have to be provided: a task name, and a task stack size. For this
- one, since it's platform dependant, you could define the best one for you in
- your lwipopts.h. For port maintainers, you can just add these new parameters
- in your sys_arch.c file, and but it's not mandatory, use them in your OS
- specific functions.
-
- 2007-09-05 Frédéric Bernon
- * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
- inside init.c for task #7142 "Sanity check user-configurable values".
-
- 2007-09-04 Frédéric Bernon, Bill Florac
- * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
- memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
- value). It will avoid potential fragmentation problems, use a counter to know
- how many times a group is used on an netif, and free it when all applications
- leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
- check if LWIP_IGMP!=0).
-
- 2007-09-03 Frédéric Bernon
- * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
- Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
- the netif's "init" function). Use the "imr_interface" field (for socket layer)
- and/or the "interface" field (for netconn layer), for join/leave operations.
- The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
- This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
-
- 2007-08-30 Frédéric Bernon
- * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
- from api/api_lib". Now netbuf API is independant of netconn, and can be used
- with other API (application based on raw API, or future "socket2" API). Ports
- maintainers just have to add src/api/netbuf.c in their makefile/projects.
-
- 2007-08-30 Frédéric Bernon, Jonathan Larmour
- * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
- user-configurable values".
-
- 2007-08-29 Frédéric Bernon
- * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
- igmp_start is call inside netif_add. Now, igmp initialization is in the same
- spirit than the others modules. Modify some IGMP debug traces.
-
- 2007-08-29 Frédéric Bernon
- * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
- Add lwip_init function to regroup all modules initializations, and to provide
- a place to add code for task #7142 "Sanity check user-configurable values".
- Ports maintainers should remove direct initializations calls from their code,
- and add init.c in their makefiles. Note that lwip_init() function is called
- inside tcpip_init, but can also be used by raw api users since all calls are
- disabled when matching options are disabled. Also note that their is new options
- in opt.h, you should configure in your lwipopts.h (they are enabled per default).
-
- 2007-08-26 Marc Boucher
- * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
- since they can under certain circumstances be called with an invalid conn
- pointer after the connection has been closed (and conn has been freed).
-
- 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
- * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
- Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
-
- 2007-08-22 Frédéric Bernon
- * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
- to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
-
- 2007-08-22 Frédéric Bernon
- * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
- ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
- name is tcpip_input (we keep the name of 1.2.0 function).
-
- 2007-08-17 Jared Grubb
- * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
- settings into new memp_std.h and optional user file lwippools.h. This adds
- more dynamic mempools, and allows the user to create an arbitrary number of
- mempools for mem_malloc.
-
- 2007-08-16 Marc Boucher
- * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
- otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
- close the connection.
-
- 2007-08-16 Marc Boucher
- * sockets.c: lwip_accept(): check netconn_peer() error return.
-
- 2007-08-16 Marc Boucher
- * mem.c, mem.h: Added mem_calloc().
-
- 2007-08-16 Marc Boucher
- * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
- for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
- and starving other message types.
- Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
-
- 2007-08-16 Marc Boucher
- * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
- type and flgs (later renamed to flags).
- Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
- Improved lwip_recvfrom(). TCP push now propagated.
-
- 2007-08-16 Marc Boucher
- * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
- provided by etharp.
-
- 2007-08-16 Marc Boucher
- * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
- etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
- Added PPPoE support and various PPP improvements.
-
- 2007-07-25 Simon Goldschmidt
- * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
- making netbuf_copy_partial use this function.
-
- 2007-07-25 Simon Goldschmidt
- * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
- 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
- other stacks.
-
- 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
- * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
- a link callback in the netif struct, and functions to handle it. Be carefull
- for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
- if you want to be sure to be compatible with future changes...
-
- 2007-06-30 Frédéric Bernon
- * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
-
- 2007-06-21 Simon Goldschmidt
- * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
- LWIP_AUTOIP =0 and =1 to remove redundant code.
-
- 2007-06-21 Simon Goldschmidt
- * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
- MEM_USE_POOLS to use 4 pools with different sized elements instead of a
- heap. This both prevents memory fragmentation and gives a higher speed
- at the cost of more memory consumption. Turned off by default.
-
- 2007-06-21 Simon Goldschmidt
- * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
- netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
- int to be able to send a bigger buffer than 64K with one time (mainly
- used from lwip_send).
-
- 2007-06-21 Simon Goldschmidt
- * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
- into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
-
- 2007-06-21 Simon Goldschmidt
- * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
- netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
- changes on low memory or empty send-buffer.
-
- 2007-06-18 Simon Goldschmidt
- * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
- of 6 to avoid loading netif->hwaddr_len every time (since this file is only
- used for ethernet and struct eth_addr already had a defined length of 6).
-
- 2007-06-17 Simon Goldschmidt
- * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
- to disable UDP checksum generation on transmit.
-
- 2007-06-13 Frédéric Bernon, Simon Goldschmidt
- * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
- pointers or parameters, and let the possibility to redefined it in cc.h. Use
- this macro to check "conn" parameter in api_msg.c functions.
-
- 2007-06-11 Simon Goldschmidt
- * sockets.c, sockets.h: Added UDP lite support for sockets
-
- 2007-06-10 Simon Goldschmidt
- * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
- by default) to switch off UDP-Lite support if not needed (reduces udp.c code
- size)
-
- 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
- * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
- AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
- LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
- (see TODO mark in the source code).
-
- 2007-06-09 Simon Goldschmidt
- * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
- etharp_output() to match netif->output so etharp_output() can be used
- directly as netif->output to save one function call.
-
- 2007-06-08 Simon Goldschmidt
- * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
- NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
- added initialization of those to ethernetif, slipif and loopif.
-
- 2007-05-18 Simon Goldschmidt
- * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
- (defaulting to off for now) that can be set to 0 to send fragmented
- packets by passing PBUF_REFs down the stack.
-
- 2007-05-23 Frédéric Bernon
- * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
- connections, such present in patch #5959.
-
- 2007-05-23 Frédéric Bernon
- * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
- code in only one part...
-
- 2007-05-18 Simon Goldschmidt
- * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
- elements to overflow. This is achieved by adding some bytes before and after
- each pool element (increasing their size, of course), filling them with a
- prominent value and checking them on freeing the element.
- Set it to 2 to also check every element in every pool each time memp_malloc()
- or memp_free() is called (slower but more helpful).
-
- 2007-05-10 Simon Goldschmidt
- * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
- PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
- code size.
-
- 2007-05-11 Frédéric Bernon
- * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
- Include a function pointer instead of a table index in the message to reduce
- footprint. Disable some part of lwip_send and lwip_sendto if some options are
- not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
-
- 2007-05-10 Simon Goldschmidt
- * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
- \ extern "C" {' in all header files. Now you can write your application using
- the lwIP stack in C++ and simply #include the core files. Note I have left
- out the netif/ppp/*h header files for now, since I don't know which files are
- included by applications and which are for internal use only.
-
- 2007-05-09 Simon Goldschmidt
- * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
- memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
- situations where some compilers might inline the copy and save a function
- call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
-
- 2007-05-08 Simon Goldschmidt
- * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
- to be overriden in case the C-library malloc implementation is not protected
- against concurrent access.
-
- 2007-05-04 Simon Goldschmidt (Atte Kojo)
- * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
- multiple packets to the same host.
-
- 2007-05-04 Frédéric Bernon, Jonathan Larmour
- * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
- to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
- netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
- sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
- Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
- these fields are now renamed "addr" & "port".
-
- 2007-04-11 Jonathan Larmour
- * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
- sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
- with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
- by the port in sys_arch.h if desired.
-
- 2007-04-06 Frédéric Bernon, Simon Goldschmidt
- * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
- allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
- clients, using new functions from netifapi.h. Disable as default (no port change to do).
-
- 2007-04-05 Frédéric Bernon
- * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
-
- 2007-04-04 Simon Goldschmidt
- * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
- use this for and architecture-independent form to tell the compiler you intentionally
- are not using this variable. Can be overriden in cc.h.
-
- 2007-03-28 Frédéric Bernon
- * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
- define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
- string, point on one of your's ethernetif field, or alloc a string you will free yourself).
- It will be used by DHCP to register a client hostname, but can also be use when you call
- snmp_set_sysname.
-
- 2007-03-28 Frédéric Bernon
- * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
- initialize a network interface's flag with. It tell this interface is an ethernet
- device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
- Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
-
- 2007-03-26 Frédéric Bernon, Jonathan Larmour
- * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
- time if you only use PPP or SLIP. The default is enable. Note we don't have to call
- etharp_init in your port's initilization sequence if you use tcpip.c, because this call
- is done in tcpip_init function.
-
- 2007-03-22 Frédéric Bernon
- * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
- new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
- your lwipopts.h. More, unused counters are not defined in the stats structs, and not
- display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
- but never used. Fix msg_in.c with the correct #if test for a stat display.
-
- 2007-03-21 Kieran Mansley
- * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
- Provides callback on netif up/down state change.
-
- 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
- * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
- ip.c, netif.h, tcpip.c, opt.h:
- New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
- filter per all network interfaces. Declare a new function in netif to enable to
- control the MAC filter (to reduce lwIP traffic processing).
-
- 2007-03-11 Frédéric Bernon
- * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
- be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
- unless you know what you're doing (default are RFC1122 compliant). Note
- that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
-
- 2007-03-08 Frédéric Bernon
- * tcp.h: Keepalive values can be configured at compile time, but don't change
- this unless you know what you're doing (default are RFC1122 compliant).
-
- 2007-03-08 Frédéric Bernon
- * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
- Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
- on UDP sockets/netconn.
-
- 2007-03-08 Simon Goldschmidt
- * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
-
- 2007-03-06 Frédéric Bernon
- * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
- Implement SO_RCVTIMEO on UDP sockets/netconn.
-
- 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
- * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
- on the stack and remove the API msg type from memp
-
- 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
- * sockets.h, sockets.c: Move socket initialization to new
- lwip_socket_init() function.
- NOTE: this changes the API with ports. Ports will have to be
- updated to call lwip_socket_init() now.
-
- 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
- * api_lib.c: Use memcpy in netbuf_copy_partial.
-
-
- ++ Bug fixes:
-
- 2008-03-17 Frédéric Bernon, Ed Kerekes
- * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
- some problems to fill the IP header on some targets, use now the
- ip.h macros to do it).
-
- 2008-03-13 Frédéric Bernon
- * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
- (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
- TCP connection caused a crash. Note that using (lwip_)recvfrom
- like this is a bit slow and that using (lwip)getpeername is the
- good lwip way to do it (so, using recv is faster on tcp sockets).
-
- 2008-03-12 Frédéric Bernon, Jonathan Larmour
- * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
- recv_raw() does not consume data", and the ping sample (with
- LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
- returned the IP payload, without the IP header).
-
- 2008-03-04 Jonathan Larmour
- * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
- and/or warnings on some systems where mem_size_t and size_t differ.
- * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
-
- 2008-03-04 Kieran Mansley (contributions by others)
- * Numerous small compiler error/warning fixes from contributions to
- mailing list after 1.3.0 release candidate made.
-
- 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
- * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
-
- 2008-01-15 Kieran Mansley
- * tcp_out.c: BUG20511. Modify persist timer to start when we are
- prevented from sending by a small send window, not just a zero
- send window.
-
- 2008-01-09 Jonathan Larmour
- * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
- conflict with Linux system headers.
-
- 2008-01-06 Jonathan Larmour
- * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
- address entirely on receiving a DHCPNAK, and restarting discovery.
-
- 2007-12-21 Simon Goldschmidt
- * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
- is not protected" by using new macros for interlocked access to modify/test
- netconn->recv_avail.
-
- 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
- * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
-
- 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
- * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
- of silly window avoidance and prevent lwIP from shrinking the window)
-
- 2007-12-04 Simon Goldschmidt
- * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
- data packet was lost): add assert that all segment lists are empty in
- tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
- state from LAST_ACK in tcp_process
-
- 2007-12-02 Simon Goldschmidt
- * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
- If including <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 Frédéric Bernon
- * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
- of the netconn_peer and netconn_addr processing is done inside tcpip_thread
- context in do_getaddr.
-
- 2007-11-10 Simon Goldschmidt
- * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
- happen any time). Now the packet simply isn't enqueued when out of memory.
-
- 2007-11-01 Simon Goldschmidt
- * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
- TCP_MSS if that is smaller) as long as no MSS option is received from the
- remote host.
-
- 2007-11-01 Simon Goldschmidt
- * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
- is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
- sending our configured TCP_MSS instead of the one received).
-
- 2007-11-01 Simon Goldschmidt
- * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
- calculated based on the configured TCP_MSS, not on the MSS option received
- with SYN+ACK.
-
- 2007-10-09 Simon Goldschmidt
- * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
- short and also was generated wrong if checksum coverage != tot_len;
- receive: checksum was calculated wrong if checksum coverage != tot_len
-
- 2007-10-08 Simon Goldschmidt
- * mem.c: lfree was not updated in mem_realloc!
-
- 2007-10-07 Frédéric Bernon
- * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
- crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
- this change cause an API breakage for netconn_addr, since a parameter
- type change. Any compiler should cause an error without any changes in
- yours netconn_peer calls (so, it can't be a "silent change"). It also
- reduce a little bit the footprint for socket layer (lwip_getpeername &
- lwip_getsockname use now a common lwip_getaddrname function since
- netconn_peer & netconn_addr have the same parameters).
-
- 2007-09-20 Simon Goldschmidt
- * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
- by checking tcp_tw_pcbs also
-
- 2007-09-19 Simon Goldschmidt
- * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
-
- 2007-09-15 Mike Kleshov
- * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
-
- 2007-09-06 Frédéric Bernon
- * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
- it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
- already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
- if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
-
- 2007-08-30 Frédéric Bernon
- * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
- and fix some coding style.
-
- 2007-08-28 Frédéric Bernon
- * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
- kind of packets. These packets are considered like Ethernet packets (payload
- pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
- are considered like IP packets (payload pointing to iphdr).
-
- 2007-08-27 Frédéric Bernon
- * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
- problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
- and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
-
- 2007-08-24 Kieran Mansley
- * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
- compiler (Paradigm C++)
-
- 2007-08-09 Frédéric Bernon, Bill Florac
- * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
- Introduce IGMP_STATS to centralize statistics management.
-
- 2007-08-09 Frédéric Bernon, Bill Florac
- * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
- packet on a udp pcb binded on an netif's IP address, and not on "any".
-
- 2007-08-09 Frédéric Bernon, Bill Florac
- * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
- This is mainly on using lookup/lookfor, and some coding styles...
-
- 2007-07-26 Frédéric Bernon (and "thedoctor")
- * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
-
- 2007-07-25 Simon Goldschmidt
- * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
- tcp_output fails in tcp_close, the code in do_close_internal gets simpler
- (tcp_output is called again later from tcp timers).
-
- 2007-07-25 Simon Goldschmidt
- * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
- copy_from_pbuf, which illegally modified the given pbuf.
-
- 2007-07-25 Simon Goldschmidt
- * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
- changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
-
- 2007-07-24 Simon Goldschmidt
- * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
- correct state (must be CLOSED).
-
- 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
- * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
- allocation. It now returns NULL.
-
- 2007-07-13 Frédéric Bernon
- * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
- all error cases.
-
- 2007-07-13 Frédéric Bernon
- * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
- because current code doesn't follow rawapi.txt documentation.
-
- 2007-07-13 Kieran Mansley
- * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
- out of sequence processing of received packets
-
- 2007-07-03 Simon Goldschmidt
- * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
- assumption is made that this pbuf is in one piece (i.e. not chained). These
- assumptions clash with the possibility of converting to fully pool-based
- pbuf implementations, where PBUF_RAM pbufs might be chained.
-
- 2007-07-03 Simon Goldschmidt
- * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
- when closing tcp netconns: removed conn->sem, less context switches when
- closing, both netconn_close and netconn_delete should safely close tcp
- connections.
-
- 2007-07-02 Simon Goldschmidt
- * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
- tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
- to cache ARP table indices with each pcb instead of single-entry cache for
- the complete stack.
-
- 2007-07-02 Simon Goldschmidt
- * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
- warnings when assigning to smaller types.
-
- 2007-06-28 Simon Goldschmidt
- * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
-
- 2007-06-28 Simon Goldschmidt
- * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
- a segment contained chained pbufs)
-
- 2007-06-28 Frédéric Bernon
- * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
- a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
- possible to define this macro in your own lwipopts.h to always use C library's
- rand(). Note that autoip_create_rand_addr doesn't use this macro.
-
- 2007-06-28 Frédéric Bernon
- * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
- LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
- in api_lib/api_msg (use pointers and not type with table, etc...)
-
- 2007-06-26 Simon Goldschmidt
- * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
-
- 2007-06-25 Simon Goldschmidt
- * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
- for udp packets with no matching pcb.
-
- 2007-06-25 Simon Goldschmidt
- * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
- could get udp input packets if the remote side matched.
-
- 2007-06-13 Simon Goldschmidt
- * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
- changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
-
- 2007-06-13 Simon Goldschmidt
- * api_msg.c: pcb_new sets conn->err if protocol is not implemented
- -> netconn_new_..() does not allocate a new connection for unsupported
- protocols.
-
- 2007-06-13 Frédéric Bernon, Simon Goldschmidt
- * api_lib.c: change return expression in netconn_addr and netconn_peer, because
- conn->err was reset to ERR_OK without any reasons (and error was lost)...
-
- 2007-06-13 Frédéric Bernon, Matthias Weisser
- * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
- MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
- some macro names collision with some OS macros.
-
- 2007-06-11 Simon Goldschmidt
- * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
- create checksum over the complete packet. On RX, if it's < 8 (and not 0),
- discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
- UDP & UDP Lite.
-
- 2007-06-11 Srinivas Gollakota & Oleg Tyshev
- * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
- where TCP flags wasn't initialized in tcp_keepalive.
-
- 2007-06-03 Simon Goldschmidt
- * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
- registered, p->payload was modified without modifying p->len if sending
- icmp_dest_unreach() (had no negative effect but was definitively wrong).
-
- 2007-06-03 Simon Goldschmidt
- * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
- re-used the input pbuf even if that didn't have enough space to include the
- link headers. Now the space is tested and a new pbuf is allocated for the
- echo response packet if the echo request pbuf isn't big enough.
-
- 2007-06-01 Simon Goldschmidt
- * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
-
- 2007-05-23 Frédéric Bernon
- * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
- allocated by do_listen if success) and netconn_accept errors handling. In
- most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
- by ASSERT, except for netconn_delete.
-
- 2007-05-23 Frédéric Bernon
- * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
- an error code if it's impossible to fetch a pbuf on a TCP connection (and not
- directly close the recvmbox).
-
- 2007-05-22 Simon Goldschmidt
- * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
- bound but unconnected (and non-listening) tcp_pcbs.
-
- 2007-05-22 Frédéric Bernon
- * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
- used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
- sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
- like "sys_timeout" in their application threads.
-
- 2007-05-22 Frédéric Bernon
- * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
- which parameters are used by which do_xxx function, and to avoid "misusing"
- parameters (patch #5938).
-
- 2007-05-22 Simon Goldschmidt
- * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
- changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
- is only 8 bits wide. This affects the api, as there, the protocol was
- u16_t, too.
-
- 2007-05-18 Simon Goldschmidt
- * memp.c: addition to patch #5913: smaller pointer was returned but
- memp_memory was the same size -> did not save memory.
-
- 2007-05-16 Simon Goldschmidt
- * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
- != ERR_OK.
-
- 2007-05-16 Simon Goldschmidt
- * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
- as the one of the netif used for sending to prevent sending from old
- addresses after a netif address gets changed (partly fixes bug #3168).
-
- 2007-05-16 Frédéric Bernon
- * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
- with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
- tcpip_init) because we have to be sure that network interfaces are already
- added (mac filter is updated only in igmp_init for the moment).
-
- 2007-05-16 Simon Goldschmidt
- * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
- into sys_arch_sem_wait calls to prevent timers from running while waiting
- for the heap. This fixes bug #19167.
-
- 2007-05-13 Simon Goldschmidt
- * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
- for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
- tcp.h to sockets.h.
-
- 2007-05-07 Simon Goldschmidt
- * mem.c: Another attempt to fix bug #17922.
-
- 2007-05-04 Simon Goldschmidt
- * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
- implementation so that it can be reused (don't allocate the target
- pbuf inside pbuf_copy()).
-
- 2007-05-04 Simon Goldschmidt
- * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
- to save a little RAM (next pointer of memp is not used while not in pool).
-
- 2007-05-03 "maq"
- * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
- (patch #3574).
-
- 2007-04-23 Simon Goldschmidt
- * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
- in NULL reference for incoming TCP packets". Loopif has to be configured
- (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
- (multithreading environments, e.g. netif->input() = tcpip_input()) or
- putting packets on a list that is fed to the stack by calling loopif_poll()
- (single-thread / NO_SYS / polling environment where e.g.
- netif->input() = ip_input).
-
- 2007-04-17 Jonathan Larmour
- * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
- the difference between two u16_t's.
- * sockets.h: FD_SETSIZE needs to match number of sockets, which is
- MEMP_NUM_NETCONN in sockets.c right now.
-
- 2007-04-12 Jonathan Larmour
- * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
-
- 2007-04-12 Kieran Mansley
- * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
- timer is reset to fix bug#19434, with help from Oleg Tyshev.
-
- 2007-04-11 Simon Goldschmidt
- * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
- previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
- pbuf.c: removed functions no needed any more (by etharp).
-
- 2007-04-11 Kieran Mansley
- * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
- "Constant is long" warnings with 16bit compilers. Contributed by
- avatar@mmlab.cse.yzu.edu.tw
-
- 2007-04-05 Frédéric Bernon, Jonathan Larmour
- * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
- the mailbox is active". Now, the post is only done during a connect, and do_send,
- do_write and do_join_leave_group don't do anything if a previous error was signaled.
-
- 2007-04-03 Frédéric Bernon
- * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
- packets. See patch #5834.
-
- 2007-03-30 Frédéric Bernon
- * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
- missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
-
- 2007-03-30 Frédéric Bernon
- * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
- others environment defines (these were too "generic").
-
- 2007-03-28 Frédéric Bernon
- * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
- result and can cause a crash. lwip_send now check netbuf_ref result.
-
- 2007-03-28 Simon Goldschmidt
- * sockets.c Remove "#include <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 Frédéric Bernon (based on patch from Dmitry Potapov)
- * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
- to send some garbage. It is not a definitive solution, but the patch does solve
- the problem for most cases.
-
- 2007-03-22 Frédéric Bernon
- * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
-
- 2007-03-22 Frédéric Bernon
- * api_lib.c: somes resources couldn't be freed if there was errors during
- netconn_new_with_proto_and_callback.
-
- 2007-03-22 Frédéric Bernon
- * ethernetif.c: update netif->input calls to check return value. In older ports,
- it's a good idea to upgrade them, even if before, there could be another problem
- (access to an uninitialized mailbox).
-
- 2007-03-21 Simon Goldschmidt
- * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
- by casting to unsigned).
-
- 2007-03-21 Frédéric Bernon
- * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
- api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
- dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
- Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
- faster and more reliable communication between api_lib and tcpip.
-
- 2007-03-21 Frédéric Bernon
- * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
-
- 2007-03-21 Frédéric Bernon
- * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
-
- 2007-03-21 Kieran Mansley
- * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
- IP and TCP headers
-
- 2007-03-21 Kieran Mansley
- * Fix all uses of pbuf_header to check the return value. In some
- cases just assert if it fails as I'm not sure how to fix them, but
- this is no worse than before when they would carry on regardless
- of the failure.
-
- 2007-03-21 Kieran Mansley
- * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
- comment out missing header include in icmp.c
-
- 2007-03-20 Frédéric Bernon
- * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
- synchronized with memp.h.
-
- 2007-03-20 Frédéric Bernon
- * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
- tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
- network interfaces. 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 Frédéric Bernon
- * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
- and api_msg_post().
-
- 2007-03-19 Frédéric 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 Frédéric 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 Frédéric 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 Frédéric 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 Frédéric Bernon
- * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
- ETHARP_TRUST_IP_MAC, review SO_REUSE)
-
- 2007-03-04 Frédéric Bernon
- * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
- referenced.
-
- 2007-03-04 Frédéric 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 Frédéric 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 Frédéric 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
-
- 2006-07-14 Christiaan Simons
- * mib_structs.c: added
- * include/lwip/snmp_structs.h: added
- * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
-
- 2006-07-06 Christiaan Simons
- * snmp/asn1_{enc,dec}.c added
- * snmp/mib2.c added
- * snmp/msg_{in,out}.c added

- * doc/snmp_agent.txt added
-
- 2006-03-29 Christiaan Simons
- * inet.c, inet.h: Added platform byteswap support.
- Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
- optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
-
- ++ Bug fixes:
-
- 2006-11-30 Christiaan Simons
- * dhcp.c: Fixed false triggers of request_timeout.
-
- 2006-11-28 Christiaan Simons
- * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.
-
- 2006-10-11 Christiaan Simons
- * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
- Partially accepted patch #5449 for ANSI C compatibility / build fixes.
- * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
- identifier from 170 to 136 (bug #17574).
-
- 2006-10-10 Christiaan Simons
- * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
-
- 2006-08-17 Christiaan Simons
- * udp.c: Fixed bug #17200, added check for broadcast
- destinations for PCBs bound to a unicast address.
-
- 2006-08-07 Christiaan Simons
- * api_msg.c: Flushing TCP output in do_close() (bug #15926).
-
- 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
- * api_lib.c: Removed conn->sem creation and destruction
- 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.

-
- 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.
-

-
-(STABLE-0_6_4)
-

-
- ++ 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.

- 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:
-

- 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.
-

-
- * 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.
-

- * Redesigned operating system emulation layer to make porting easier.
-
- * Better control over TCP output buffers.
-
- * Documenation added.
-
- ++ Bugfixes:

-
-(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.
-
