5941b3c86e 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. 2008-01-05 21:10:32 +00:00

113a52d091 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. 2007-12-02 14:53:50 +00:00
goldsimon
6746beb2a3 Compacted code: moved the code creating a netconn (without pcb) from netconn_new_with_proto_and_callback to new (synchroneous) function netconn_alloc_with_proto_and_callback and call this function from netconn_new_with_proto_and_callback and accept_function. 2007-11-30 12:54:10 +00:00

03777ccb21 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 21:15:44 +00:00

f3dbd986cb 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. 2007-11-06 20:31:28 +00:00
fbernon
ecce865cfe 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). 2007-11-02 10:37:08 +00:00

cbe9b050a9 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". 2007-11-01 17:37:50 +00:00
fbernon
7077d51f1f 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. 2007-10-24 12:09:18 +00:00

270c7c1110 Removed check for conn->err for functions whose counterparts in api_msg.c also do the check (1. remove redundant code, 2. check is better done in tcpip thread context) 2007-10-22 20:01:16 +00:00

87e16a8f47 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_peer, 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). 2007-10-07 17:26:54 +00:00

245bce04d1 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 16:55:10 +00:00

eb875de67e 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 20:28:35 +00:00

Now, users SHOULD NOT use internal lwIP features like "sys_timeout" in their application threads. 2007-05-22 20:51:34 +00:00
fbernon
499f4689be 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 09:54:00 +00:00

9cf1390dc6 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). 2007-05-11 08:58:23 +00:00

255d5a748f 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(). 2007-05-10 05:20:05 +00:00

5a12aeb4a1 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". 2007-05-04 15:18:29 +00:00

3eb38d7611 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 16:38:58 +00:00

32d9f25a6f Fixed up and made work a PBUF_REF type. Most of the code uses this now 
instead of PBUF_ROM. This addition allows support of copy-on-demand where the
lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and
replaces them with PBUF_POOL buffers. This is now used
everywhere. pbuf_unref() is called in ARP queueing and in the coldfire
driver, which puts frames on a DMA queue and frees them later.

Along with this change pbuf_free() now goes through the entire chain of
buffers and tests all the ref counters, not just the first one. Generally now
pbuf_ref_chain() should be called and not pbuf_ref(). This change was made
because it is possible for the head of the pbuf chain to have a different
count than the payload pbuf which might have been passed by the application.

dd2fa15e8a Add the following features and bugfixes: 
Added select() functionality to sockets library.
Support for errno in sockets library.
Byte ordering fixes.
basic lwip_ioctl(), FIONREAD, get/setsockopt() etc. support

- added additional argument to netif_add to pass state pointer so that the
if_init function has access to context information before
the interface is added, without accessing globals.

- added netif_remove()

- to conserve cpu load the tcpip_tcp_timer should only be active
when tcbs that need it exist.

- pass length of available data to callbacks for NETCONN_EVT_RCV events

- added tcpip_link_input(), a hack to allow processing of PPP
packets in tcpip_thread() context. This saves threads and context
switches.

- renamed incompatible ASSERT() macro to LWIP_ASSERT() to avoid name
collision.

- changed a bunch of %d's to %u's in format strings for unsigned values.

- added ip_frag to lwip_stats.

- changed IP_REASS_MAXAGE and IP_REASS_TMO defaults to more realistic
values.

- added sys_timeout_remove() function to cancel timeouts (needed by PPP
amongst other things).

- tolerate NULL returns from sys_arch_timeouts() since some threads might
not need to use or have timeouts.

- added sys_sem_wait_timeout()

- moved mem_malloc() function to end of mem.c to work around tasking
compiler bug.

- automatically bind to local tcp port if 0.

- allow customization of port ranges for automatic local bindings.

- corrected various typos, spelling errors, etc..

Thanks to Marc Boucher for many of these changes.

6d0a8a85c7 Fix locking for disconnect operation (use post and fetch on the connection's mbox in the two threads like other operations).Make netconn_peer take a pointer to addr instead of pointer to pointer to addr.Addr is a 4 byte struct an IP address so use structure assignment not just pointer assignment when saving the peer.This way the address is really saved :fixes bug #1897 2003-01-24 09:24:44 +00:00
