bcd4b76d31 Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains the actual application programmer's API 2010-02-21 11:35:21 +00:00

cbfacb7ed9 bug #26213 "Problem with memory allocation when debugging": memp_sizes contained the wrong sizes (including sanity regions); memp pools for MEM_USE_POOLS were too small; Added option MEM_USE_POOLS_TRY_BIGGER_POOL to try the next bigger malloc pool if one is empty (only usable with MEM_USE_POOLS). 2009-04-25 17:42:27 +00:00

c4509e700d added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc is otherwise used) 2009-02-11 20:43:41 +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

d4616a7fc6 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). 2007-09-04 15:15:20 +00:00

0167bbb89a Per Frederic's suggestion, renamed
[MEMP_[NUM_]]TCPIP_MSG to [MEMP_[NUM_]]TCPIP_MSG_API
and
    [MEMP_[NUM_]]TCPIP_MSG_INPUT to [MEMP_[NUM_]]TCPIP_MSG_INPKT.

Added defines in opt.h for temporary compatibility with older lwipopts.h.

1b98df4a0d Added distinct memp (MEMP_TCPIP_MSG_INPUT) for input packets to prevent

0c18e653e8 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 20:12:11 +00:00

680afa4229 memp_memory could be unaligned, causing one buffer in the memp pool to

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.

98fbb855fb Added lightweight protection. In coldfire this is implemented by disabling
interrupts. In unixsim this is implemented by using a mutex. Uses #define
SYS_LIGHTWEIGHT_PROT to enable. It is enabled in coldfire by default, but
disabled in unixsim.

Fixes bug 2005 if you enable SYS_LIGHTWEIGHT_PROT. So the bug is closed.
