* TODO: The lwIP source code makes some invalid assumptions on processor
|
|
word-length, storage sizes and alignment. See the mailing lists for
|
|
problems with exoteric (/DSP) architectures showing these problems.
|
|
We still have to fix some of these issues neatly.
|
|
|
|
* TODO: the PPP code is broken in a few ways. There are namespace
|
|
collisions on BSD systems and many assumptions on word-length
|
|
(sizeof(int)). In ppp.c an assumption is made on the availability of
|
|
a thread subsystem. Either PPP needs to be moved to contrib/ports/???
|
|
or rearranged to be more generic.

|
|
* 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).

|
|
* 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_frag.c: added SNMP counters.
|
|
|

|
2006-07-14 Christiaan Simons
|
|
* mib_structs.c: 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

|
|
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.
|
|
* ip_frag.c, tcp_out.c, sockets.c, pbuf.c
|
|
Small corrections to some debugging statements, to pacify compiler.
|
|
|
|
2004-07-21 Tony Mountifield <tony@softins.co.uk>
|
|
* etharp.c: Removed spurious semicolon and added missing end-of-comment.
|
|
* ethernetif.c Updated low_level_output() to match prototype for
|
|
netif->linkoutput and changed low_level_input() similarly for consistency.
|
|
* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
|
|
of raw_recv() in raw.h and so avoid compiler error.
|
|
* sockets.c: Added trivial (int) cast to keep compiler happier.
|
|
* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
|
|

|
++ 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_3)
|
|
|
|
++ Bug fixes:
|
|
|
|
* Fixed pool pbuf memory leak in pbuf_alloc().
|
|
Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
|
|
Reported by Savin Zlobec.
|
|
|
|
* PBUF_POOL chains had their tot_len field not set for non-first
|
|
pbufs. Fixed in pbuf_alloc().
|
|
|
|
++ New features:
|
|
|
|
* Added PPP stack contributed by Marc Boucher
|
|
|
|
++ Changes:
|
|
|
|
* Now drops short packets for ICMP/UDP/TCP protocols. More robust.
|
|
|
|
* ARP queueuing now queues the latest packet instead of the first.
|
|
This is the RFC recommended behaviour, but can be overridden in
|
|
lwipopts.h.
|
|
|
|
(0.6.2)
|
|
|
|
++ Bugfixes:
|
|
|
|
* TCP has been fixed to deal with the new use of the pbuf->ref
|
|
counter.
|
|
|
|
* DHCP dhcp_inform() crash bug fixed.
|
|
|
|
++ Changes:
|
|
|
|
* Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
|
|
pbuf_refresh(). This has sped up pbuf pool operations considerably.
|
|
Implemented by David Haas.
|
|
|
|
(0.6.1)
|
|
|
|
++ New features:
|
|
|
|
* The packet buffer implementation has been enhanced to support
|
|
zero-copy and copy-on-demand for packet buffers which have their
|
|
payloads in application-managed memory.
|
|
Implemented by David Haas.
|
|
|
|
Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
|
|
if an outgoing packet can be directly sent on the link, or perform
|
|
a copy-on-demand when necessary.
|
|
|
|
The application can safely assume the packet is sent, and the RAM
|
|
is available to the application directly after calling udp_send()
|
|
or similar function.
|
|
|
|
++ Bugfixes:
|
|
|
|
* ARP_QUEUEING should now correctly work for all cases, including
|
|
PBUF_REF.
|
|
Implemented by Leon Woestenberg.
|
|
|
|
++ Changes:
|
|
|
|
* IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
|
|
to a '0.0.0.0' IP address.
|
|
|
|
* The packet buffer implementation is changed. The pbuf->ref counter
|
|
meaning has changed, and several pbuf functions have been
|
|
adapted accordingly.
|
|
|
|
* netif drivers have to be changed to set the hardware address length field
|
|
that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
|
|
See the contrib/ports/c16x cs8900 driver as a driver example.
|
|
|
|
* netif's have a dhcp field that must be initialized to NULL by the driver.
|
|
See the contrib/ports/c16x cs8900 driver as a driver example.

|
|
|
|
* 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.
|
|
|
|

|
|
starvation.
|
|
|
|
* TCP MSS option wasn't parsed correctly.
|
|
|
|
* Problems with UDP checksum calculation.
|
|
|
|
* IP multicast address tests had endianess problems.
|
|
|
|
* ARP requests had wrong destination hardware address.
|
|
|
|
++ Other changes:
|
|
|
|
* struct eth_addr changed from u16_t[3] array to u8_t[6].
|
|
|
|
* A ->linkoutput() member was added to struct netif.
|

|
|
|
|
(0.5.0) Changes since version 0.4.2
|
|
|
|
++ New features:
|
|
|
|
* Redesigned operating system emulation layer to make porting easier.
|
|
|
|
* Better control over TCP output buffers.
|
|
|
|
* Documenation added.
|
|
|
|
++ Bugfixes:
|
|
|
|
* Locking issues in buffer management.
|
|
|
|
* Bugfixes in the sequential API.
|
|
|
|

|
|
|
|
(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.
|
|
