* 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). | |
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 | |
* include/lwip/snmp_asn1.h added | |
* include/lwip/snmp_msg.h 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. | |
* ip_frag.c, tcp_out.c, sockets.c, pbuf.c | |
Small corrections to some debugging statements, to pacify compiler. | |
2004-07-21 Tony Mountifield <tony@softins.co.uk> | |
* etharp.c: Removed spurious semicolon and added missing end-of-comment. | |
* ethernetif.c Updated low_level_output() to match prototype for | |
netif->linkoutput and changed low_level_input() similarly for consistency. | |
* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype | |
of raw_recv() in raw.h and so avoid compiler error. | |
* sockets.c: Added trivial (int) cast to keep compiler happier. | |
* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros. | |
(STABLE-1_0_0) | |
++ Changes: | |
2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure | |
your cc.h file defines this either 1 or 0. If non-defined, | |
defaults to 1. | |
* .c: Added <string.h> and <errno.h> includes where used. | |
* etharp.c: Made some array indices unsigned. | |
2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* netif.*: Added netif_set_up()/down(). | |
* dhcp.c: Changes to restart program flow. | |
2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* etharp.c: In find_entry(), instead of a list traversal per candidate, do a | |
single-pass lookup for different candidates. Should exploit locality. | |
2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* tcp*.c: Cleaned up source comment documentation for Doxygen processing. | |
* opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC. | |
* etharp.c: update_arp_entry() only adds new ARP entries when adviced to by | |
the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option. | |
++ Bug fixes: | |
2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution | |
suggested by Timmy Brolin. Fix for 32-bit processors that cannot access | |
non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix | |
is to prefix the 14-bit Ethernet headers with two padding bytes. | |
2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net> | |
* ip_addr.c: Fix in the ip_addr_isbroadcast() check. | |
* etharp.c: Fixed the case where the packet that initiates the ARP request | |
is not queued, and gets lost. Fixed the case where the packets destination | |
address is already known; we now always queue the packet and perform an ARP | |
request. | |
(STABLE-0_7_0) | |
++ Bug fixes: | |
* Fixed TCP bug for SYN_SENT to ESTABLISHED state transition. | |
* Fixed TCP bug in dequeueing of FIN from out of order segment queue. | |
* Fixed two possible NULL references in rare cases. | |
(STABLE-0_6_6) | |
++ Bug fixes: | |
* Fixed DHCP which did not include the IP address in DECLINE messages. | |
++ Changes: | |
* etharp.c has been hauled over a bit. | |
(STABLE-0_6_5) | |
++ Bug fixes: | |
* Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic. | |
* Packets sent from ARP queue had invalid source hardware address. | |
++ Changes: | |
* Pass-by ARP requests do now update the cache. | |
++ New features: | |
* No longer dependent on ctype.h. | |
* New socket options. | |
* Raw IP pcb support. | |
(STABLE-0_6_4) | |
++ Bug fixes: | |
* Some debug formatters and casts fixed. | |
* Numereous fixes in PPP. | |
++ Changes: | |
* DEBUGF now is LWIP_DEBUGF | |
* pbuf_dechain() has been re-enabled. | |
* Mentioned the changed use of CVS branches in README. | |
(STABLE-0_6_3) | |
++ Bug fixes: | |
* Fixed pool pbuf memory leak in pbuf_alloc(). | |
Occured if not enough PBUF_POOL pbufs for a packet pbuf chain. | |
Reported by Savin Zlobec. | |
* PBUF_POOL chains had their tot_len field not set for non-first | |
pbufs. Fixed in pbuf_alloc(). | |
++ New features: | |
* Added PPP stack contributed by Marc Boucher | |
++ Changes: | |
* Now drops short packets for ICMP/UDP/TCP protocols. More robust. | |
* ARP queueuing now queues the latest packet instead of the first. | |
This is the RFC recommended behaviour, but can be overridden in | |
lwipopts.h. | |
(0.6.2) | |
++ Bugfixes: | |
* TCP has been fixed to deal with the new use of the pbuf->ref | |
counter. | |
* DHCP dhcp_inform() crash bug fixed. | |
++ Changes: | |
* Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed | |
pbuf_refresh(). This has sped up pbuf pool operations considerably. | |
Implemented by David Haas. | |
(0.6.1) | |
++ New features: | |
* The packet buffer implementation has been enhanced to support | |
zero-copy and copy-on-demand for packet buffers which have their | |
payloads in application-managed memory. | |
Implemented by David Haas. | |
Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy | |
if an outgoing packet can be directly sent on the link, or perform | |
a copy-on-demand when necessary. | |
The application can safely assume the packet is sent, and the RAM | |
is available to the application directly after calling udp_send() | |
or similar function. | |
++ Bugfixes: | |
* ARP_QUEUEING should now correctly work for all cases, including | |
PBUF_REF. | |
Implemented by Leon Woestenberg. | |
++ Changes: | |
* IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer | |
to a '0.0.0.0' IP address. | |
* The packet buffer implementation is changed. The pbuf->ref counter | |
meaning has changed, and several pbuf functions have been | |
adapted accordingly. | |
* netif drivers have to be changed to set the hardware address length field | |
that must be initialized correctly by the driver (hint: 6 for Ethernet MAC). | |
See the contrib/ports/c16x cs8900 driver as a driver example. | |
* netif's have a dhcp field that must be initialized to NULL by the driver. | |
See the contrib/ports/c16x cs8900 driver as a driver example. | |
(0.5.x) This file has been unmaintained up to 0.6.1. All changes are | |
logged in CVS but have not been explained here. | |
(0.5.3) Changes since version 0.5.2 | |
++ Bugfixes: | |
* memp_malloc(MEMP_API_MSG) could fail with multiple application | |
threads because it wasn't protected by semaphores. | |
++ Other changes: | |
* struct ip_addr now packed. | |
* The name of the time variable in arp.c has been changed to ctime | |
to avoid conflicts with the time() function. | |
(0.5.2) Changes since version 0.5.1 | |
++ New features: | |
* A new TCP function, tcp_tmr(), now handles both TCP timers. | |
++ Bugfixes: | |
* A bug in tcp_parseopt() could cause the stack to hang because of a | |
malformed TCP option. | |
* The address of new connections in the accept() function in the BSD | |
socket library was not handled correctly. | |
* pbuf_dechain() did not update the ->tot_len field of the tail. | |
* Aborted TCP connections were not handled correctly in all | |
situations. | |
++ Other changes: | |
* All protocol header structs are now packed. | |
* The ->len field in the tcp_seg structure now counts the actual | |
amount of data, and does not add one for SYN and FIN segments. | |
(0.5.1) Changes since version 0.5.0 | |
++ New features: | |
* Possible to run as a user process under Linux. | |
* Preliminary support for cross platform packed structs. | |
* ARP timer now implemented. | |
++ Bugfixes: | |
* TCP output queue length was badly initialized when opening | |
connections. | |
* TCP delayed ACKs were not sent correctly. | |
* Explicit initialization of BSS segment variables. | |
* read() in BSD socket library could drop data. | |
* Problems with memory alignment. | |
* Situations when all TCP buffers were used could lead to | |
starvation. | |
* TCP MSS option wasn't parsed correctly. | |
* Problems with UDP checksum calculation. | |
* IP multicast address tests had endianess problems. | |
* ARP requests had wrong destination hardware address. | |
++ Other changes: | |
* struct eth_addr changed from u16_t[3] array to u8_t[6]. | |
* A ->linkoutput() member was added to struct netif. | |
* TCP and UDP ->dest_* struct members where changed to ->remote_*. | |
* ntoh* macros are now null definitions for big endian CPUs. | |
(0.5.0) Changes since version 0.4.2 | |
++ New features: | |
* Redesigned operating system emulation layer to make porting easier. | |
* Better control over TCP output buffers. | |
* Documenation added. | |
++ Bugfixes: | |
* Locking issues in buffer management. | |
* Bugfixes in the sequential API. | |
* IP forwarding could cause memory leakage. This has been fixed. | |
++ Other changes: | |
* Directory structure somewhat changed; the core/ tree has been | |
collapsed. | |
(0.4.2) Changes since version 0.4.1 | |
++ New features: | |
* Experimental ARP implementation added. | |
* Skeleton Ethernet driver added. | |
* Experimental BSD socket API library added. | |
++ Bugfixes: | |
* In very intense situations, memory leakage could occur. This has | |
been fixed. | |
++ Other changes: | |
* Variables named "data" and "code" have been renamed in order to | |
avoid name conflicts in certain compilers. | |
* Variable++ have in appliciable cases been translated to ++variable | |
since some compilers generate better code in the latter case. | |
(0.4.1) Changes since version 0.4 | |
++ New features: | |
* TCP: Connection attempts time out earlier than data | |
transmissions. Nagle algorithm implemented. Push flag set on the | |
last segment in a burst. | |
* UDP: experimental support for UDP-Lite extensions. | |
++ Bugfixes: | |
* TCP: out of order segments were in some cases handled incorrectly, | |
and this has now been fixed. Delayed acknowledgements was broken | |
in 0.4, has now been fixed. Binding to an address that is in use | |
now results in an error. Reset connections sometimes hung an | |
application; this has been fixed. | |
* Checksum calculation sometimes failed for chained pbufs with odd | |
lengths. This has been fixed. | |
* API: a lot of bug fixes in the API. The UDP API has been improved | |
and tested. Error reporting and handling has been | |
improved. Logical flaws and race conditions for incoming TCP | |
connections has been found and removed. | |
* Memory manager: alignment issues. Reallocating memory sometimes | |
failed, this has been fixed. | |
* Generic library: bcopy was flawed and has been fixed. | |
++ Other changes: | |
* API: all datatypes has been changed from generic ones such as | |
ints, to specified ones such as u16_t. Functions that return | |
errors now have the correct type (err_t). | |
* General: A lot of code cleaned up and debugging code removed. Many | |
portability issues have been fixed. | |
* The license was changed; the advertising clause was removed. | |
* C64 port added. | |
* Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri | |
Kosunen, Mikael Caleres, and Frits Wilmink for reporting and | |
fixing bugs! | |
(0.4) Changes since version 0.3.1 | |
* Memory management has been radically changed; instead of | |
allocating memory from a shared heap, memory for objects that are | |
rapidly allocated and deallocated is now kept in pools. Allocation | |
and deallocation from those memory pools is very fast. The shared | |
heap is still present but is used less frequently. | |
* The memory, memory pool, and packet buffer subsystems now support | |
4-, 2-, or 1-byte alignment. | |
* "Out of memory" situations are handled in a more robust way. | |
* Stack usage has been reduced. | |
* Easier configuration of lwIP parameters such as memory usage, | |
TTLs, statistics gathering, etc. All configuration parameters are | |
now kept in a single header file "lwipopts.h". | |
* The directory structure has been changed slightly so that all | |
architecture specific files are kept under the src/arch | |
hierarchy. | |
* Error propagation has been improved, both in the protocol modules | |
and in the API. | |
* The code for the RTXC architecture has been implemented, tested | |
and put to use. | |
* Bugs have been found and corrected in the TCP, UDP, IP, API, and | |
the Internet checksum modules. | |
* Bugs related to porting between a 32-bit and a 16-bit architecture | |
have been found and corrected. | |
* The license has been changed slightly to conform more with the | |
original BSD license, including the advertisement clause. | |
(0.3.1) Changes since version 0.3 | |
* Fix of a fatal bug in the buffer management. Pbufs with allocated | |
RAM never returned the RAM when the pbuf was deallocated. | |
* TCP congestion control, window updates and retransmissions did not | |
work correctly. This has now been fixed. | |
* Bugfixes in the API. | |
(0.3) Changes since version 0.2 | |
* New and improved directory structure. All include files are now | |
kept in a dedicated include/ directory. | |
* The API now has proper error handling. A new function, | |
netconn_err(), now returns an error code for the connection in | |
case of errors. | |
* Improvements in the memory management subsystem. The system now | |
keeps a pointer to the lowest free memory block. A new function, | |
mem_malloc2() tries to allocate memory once, and if it fails tries | |
to free some memory and retry the allocation. | |
* Much testing has been done with limited memory | |
configurations. lwIP now does a better job when overloaded. | |
* Some bugfixes and improvements to the buffer (pbuf) subsystem. | |
* Many bugfixes in the TCP code: | |
- Fixed a bug in tcp_close(). | |
- The TCP receive window was incorrectly closed when out of | |
sequence segments was received. This has been fixed. | |
- Connections are now timed-out of the FIN-WAIT-2 state. | |
- The initial congestion window could in some cases be too | |
large. This has been fixed. | |
- The retransmission queue could in some cases be screwed up. This | |
has been fixed. | |
- TCP RST flag now handled correctly. | |
- Out of sequence data was in some cases never delivered to the | |
application. This has been fixed. | |
- Retransmitted segments now contain the correct acknowledgment | |
number and advertised window. | |
- TCP retransmission timeout backoffs are not correctly computed | |
(ala BSD). After a number of retransmissions, TCP now gives up | |
the connection. | |
* TCP connections now are kept on three lists, one for active | |
connections, one for listening connections, and one for | |
connections that are in TIME-WAIT. This greatly speeds up the fast | |
timeout processing for sending delayed ACKs. | |
* TCP now provides proper feedback to the application when a | |
connection has been successfully set up. | |
* More comments have been added to the code. The code has also been | |
somewhat cleaned up. | |
(0.2) Initial public release. |
