05587f5da9 Changed the pbuf_free/mem_free callback functions a little: created extra functions for that 2008-03-28 07:56:47 +00:00

43dd38df0a fixed bug #21433 (Calling mem_free/pbuf_free from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1 in lwipopts.h or use tcpip_callback_nonblocking(pbuf_free_int, p)/ tcpip_callback_nonblocking(mem_free, m) to free pbufs or heap memory from interrupt context 2008-03-27 19:29:35 +00:00

7774b57a1c api_msg.c: fix wrong mailbox invalidate (NULL was used instead of SYS_MBOX_NULL). Spoted by Silas Boyd-Wickizer. 2008-03-21 16:23:14 +00:00

e07d71f5e8 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). 2008-03-13 20:03:57 +00:00

4e40fee1db 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 21:47:52 +00:00

bceff76c70 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". 2008-01-10 21:34:25 +00:00

a41f113b8f Added function netconn_free(), which deallocates all mboxes and frees the netconn (to be used from different places) - the PCB is not freed! 2008-01-06 14:28:04 +00:00

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

ac10470643 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. 2007-12-05 23:00:02 +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

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

dc515c7ad3 Fixed bug #20287: tcp_output_nagle sends too early. This fixes the nagle algorithm; nagle now also works for all raw API applications and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' 2007-11-21 17:59:03 +00:00

0c0e8d6544 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. 2007-11-14 23:27:13 +00:00
