|
|
|
-
|

|
|
|
-
|
|
|
-(0.4.2) Changes since version 0.4.1
|
|
|
-
|
|

|
|
|
-
|
|

|
|
|
-
|
|
|

|
|
|
-
|
|
|

|
|
|
-
|
|

|
|
|
-
|
|
|
-(0.4.1) Changes since version 0.4
|
|
|
-
|
|
|
- ++ New features:
|
|
|
-
|
|
|
- * TCP: Connection attempts time out earlier than data
|
|
|
- transmissions. 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.
