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. diff --git a/COPYING b/COPYING deleted file mode 100644 index e23898b5..00000000 --- a/COPYING +++ /dev/null @@ -1,33 +0,0 @@ -/* - * Copyright (c) 2001, 2002 Swedish Institute of Computer Science. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * - * 1.
