95425552d7 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 #21535. 2007-11-21 18:37:23 +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

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

298d5cf042 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 16:23:32 +00:00

199648ff37 Changed initialization: many init functions are not needed any more since we now rely on the compiler initializing global and static variables to zero! 2007-10-09 19:59:56 +00:00

8205737fdb 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. 2007-09-07 23:47:02 +00:00

e3cd1ac1f9 Minor changes (but in lot of files): add #if/#endif for options where they could miss. #if LWIP_xxx if always put after #include "lwip/opt.h" (note this one indirectly include cc.h). Move others includes inside #if/#endif block. 2007-09-07 23:01:59 +00:00

5ee9c95ebd Fixed a cast warning by including the type to TCP_PCB_COMMON: (Moved members common to structures tcp_pcp and tcp_listen_pcb into define TCP_PCB_COMMON (like IP_PCB) to keep (possible) code changes consistent.) 2007-06-08 12:00:45 +00:00

84fc489e0c 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. 2007-05-10 10:59:20 +00:00

5c65d4733b 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.
Old TCP_KEEPALIVE can always be used, and its only difference with TCP_KEEPIDLE is this last use seconds and not milliseconds with setsockopt.

Some documentation (not perfect, but...):

e4295396ac Re-instantiated the pack directives. Nested structs do break individual field natural alignment on arm-gcc. 2004-05-06 03:27:13 +00:00

79110ba469 Removed all structure packing directives. Protocol header fields are naturally aligned by design.
(Earlier, the 14-byte ethernet header screwed this up, this had already been fixed by adding two pad bytes.)
Assumption is that compilers do not align with larger-than-sizeof(type) boundaries.
Pre-tag PRE_PACK_REMOVE. Post-tag POST_TAG_REMOVE.

7f1becc682 Allow minimal unix target to build in cygwin (but not necessarily run).
Applied a patch from Marc Boucher which has the following changes:

1) Fixed sys_arch.txt documentation to have new return type from
   sys_thread_new.

2) Removed unnecessary casts on calling sys_timeout() in certain files.

3) Removed some unnecessary break statements after return statements.

4) Changed sys_timeout_remove() to sys_untimeout().

5) Added some forgotten #ifndef SYS_LIGHTWEIGHT_PROT to memp.c

6) Changed LWIP_DIAG and LWIP_PLATFORM_ASSERT to have do while().

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.
