75505befa93c993aa5d2df24a2b64eac0c34cbffMark Andrews * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are

f72f5879424ce4081893b306b8c31f29fe9205e0Evan Hunt in 0.4, has now been fixed. Binding to an address that is in use
f72f5879424ce4081893b306b8c31f29fe9205e0Evan Hunt now results in an error. Reset connections sometimes hung an
f72f5879424ce4081893b306b8c31f29fe9205e0Evan Hunt application; this has been fixed.
f72f5879424ce4081893b306b8c31f29fe9205e0Evan Hunt * Checksum calculation sometimes failed for chained pbufs with odd
1073e2001caee13cc1fa52de97feddd633d50fd8Evan Hunt lengths. This has been fixed.
1073e2001caee13cc1fa52de97feddd633d50fd8Evan Hunt * API: a lot of bug fixes in the API. The UDP API has been improved
1073e2001caee13cc1fa52de97feddd633d50fd8Evan Hunt and tested. Error reporting and handling has been

6727802528c27484e0d36d70f0b936022d3226e3Michał Kępień * Memory management has been radically changed; instead of
6727802528c27484e0d36d70f0b936022d3226e3Michał Kępień allocating memory from a shared heap, memory for objects that are
6727802528c27484e0d36d70f0b936022d3226e3Michał Kępień rapidly allocated and deallocated is now kept in pools. Allocation
4d41be5f9e86c11a6f00e2b005cfc5abae2c1ab3Mark Andrews and deallocation from those memory pools is very fast. The shared
4d41be5f9e86c11a6f00e2b005cfc5abae2c1ab3Mark Andrews heap is still present but is used less frequently.
bfde61d5194a534d800f3b90008d1f52261922c5Mark Andrews * The memory, memory pool, and packet buffer subsystems now support
bfde61d5194a534d800f3b90008d1f52261922c5Mark Andrews 4-, 2-, or 1-byte alignment.
6b56350522d18f10edbf2d3778cd0fea74e4f3d2Mark Andrews * "Out of memory" situations are handled in a more robust way.

16f43564c6875e2bedd346c18c494933ad51e4faMukund Sivaraman * Easier configuration of lwIP parameters such as memory usage,
16f43564c6875e2bedd346c18c494933ad51e4faMukund Sivaraman TTLs, statistics gathering, etc. All configuration parameters are
16f43564c6875e2bedd346c18c494933ad51e4faMukund Sivaraman now kept in a single header file "lwipopts.h".
16f43564c6875e2bedd346c18c494933ad51e4faMukund Sivaraman * The directory structure has been changed slightly so that all
72b322cde0e51c4c87df0c9e3226deac95dfb4ceMark Andrews architecture specific files are kept under the src/arch
28ea558bc80f75e46d77ea0533232bb9d4e644f7Mark Andrews * Error propagation has been improved, both in the protocol modules
8ed6c49f1a7f06d3ed39bee7731ff91d8dfd8dc7Mark Andrews and in the API.
447dfe4f115b17274eabf1087f035634e1129bb9Mark Andrews * The code for the RTXC architecture has been implemented, tested
565535d1820c63c64ec3c89e1f4815c326aed7aeEvan Hunt and put to use.
6045abbc9a0d7d449a13b6fbfbf32d419b6bee96Mark Andrews * Bugs have been found and corrected in the TCP, UDP, IP, API, and
f7d148398ca4511551c737e655b15f7d0d59a783Mark Andrews the Internet checksum modules.
f7d148398ca4511551c737e655b15f7d0d59a783Mark Andrews * Bugs related to porting between a 32-bit and a 16-bit architecture
3a84275b10ab16965e86f6ca97e70c1bdca885a0Mark Andrews have been found and corrected.
3a84275b10ab16965e86f6ca97e70c1bdca885a0Mark Andrews * The license has been changed slightly to conform more with the
3a84275b10ab16965e86f6ca97e70c1bdca885a0Mark Andrews original BSD license, including the advertisement clause.
398834f7559617bdfd6c10ba555609a2f306e3d4Mark Andrews(0.3.1) Changes since version 0.3
398834f7559617bdfd6c10ba555609a2f306e3d4Mark Andrews * Fix of a fatal bug in the buffer management. Pbufs with allocated
398834f7559617bdfd6c10ba555609a2f306e3d4Mark Andrews RAM never returned the RAM when the pbuf was deallocated.
28061f80b698171892e81c0856bc722190947998Evan Hunt * TCP congestion control, window updates and retransmissions did not
28061f80b698171892e81c0856bc722190947998Evan Hunt work correctly. This has now been fixed.
a785bf2c39c6f223a93c27bbff81591b38095577Mark Andrews * Bugfixes in the API.
a03f4b1ea4f1a4a70963fbeb606841c217f9e5f3Evan Hunt(0.3) Changes since version 0.2
a03f4b1ea4f1a4a70963fbeb606841c217f9e5f3Evan Hunt * New and improved directory structure. All include files are now
d315545e6db6792692fe2dcb788ac6717a33b75fEvan Hunt kept in a dedicated include/ directory.
d315545e6db6792692fe2dcb788ac6717a33b75fEvan Hunt * The API now has proper error handling. A new function,
d315545e6db6792692fe2dcb788ac6717a33b75fEvan Hunt netconn_err(), now returns an error code for the connection in
00f131293520b70728cd48840e09953fa45a745bMark Andrews case of errors.
00f131293520b70728cd48840e09953fa45a745bMark Andrews * Improvements in the memory management subsystem. The system now
b2e71853060a384070d422afda6d1c692ff608e3Mark Andrews keeps a pointer to the lowest free memory block. A new function,
b2e71853060a384070d422afda6d1c692ff608e3Mark Andrews mem_malloc2() tries to allocate memory once, and if it fails tries
b2e71853060a384070d422afda6d1c692ff608e3Mark Andrews to free some memory and retry the allocation.
42c1acfa478aacfbda2d298cf74a137de2df4b87Michał Kępień * Much testing has been done with limited memory
42c1acfa478aacfbda2d298cf74a137de2df4b87Michał Kępień configurations. lwIP now does a better job when overloaded.
214b53880b6d77359f60feccb91bd2589059300aEvan Hunt * Some bugfixes and improvements to the buffer (pbuf) subsystem.
214b53880b6d77359f60feccb91bd2589059300aEvan Hunt * Many bugfixes in the TCP code:
dd5375de0a7a515ee4fb2fd217e9577259d38c07Mark Andrews - Fixed a bug in tcp_close().
3a58e1fefb0a9fd5dab11f271a320c6b90473f76Mukund Sivaraman - The TCP receive window was incorrectly closed when out of
3a58e1fefb0a9fd5dab11f271a320c6b90473f76Mukund Sivaraman sequence segments was received. This has been fixed.
7c67b8c2b076971e6a9f8b0db932201366f13d47Mark Andrews - Connections are now timed-out of the FIN-WAIT-2 state.
7c67b8c2b076971e6a9f8b0db932201366f13d47Mark Andrews - The initial congestion window could in some cases be too
5aed5dc329a2bf1340e9ff2256c1cf4e3005ea0bMark Andrews large. This has been fixed.
387f5e872d40426acbc739d2e9b2bb37c123dd56Mark Andrews - The retransmission queue could in some cases be screwed up. This
8664a1bd40814ed0b42eacfc5eb354b598dfd6dfTinderbox User has been fixed.
c28e44f3f8bc46c6bf1c15cc06af0c42fcd7e924Evan Hunt - TCP RST flag now handled correctly.
3440cf9c60cd5d35634e7f274fd3eccbba2173a5Evan Hunt - Out of sequence data was in some cases never delivered to the
3440cf9c60cd5d35634e7f274fd3eccbba2173a5Evan Hunt application. This has been fixed.
387f5e872d40426acbc739d2e9b2bb37c123dd56Mark Andrews - Retransmitted segments now contain the correct acknowledgment
541ce84ff2f0c54340da8b3e04c5686ed82420e1Mark Andrews number and advertised window.
032d2134a4c1808696688db9bf6f20253e5d05b5Mark Andrews - TCP retransmission timeout backoffs are not correctly computed
032d2134a4c1808696688db9bf6f20253e5d05b5Mark Andrews (ala BSD). After a number of retransmissions, TCP now gives up
032d2134a4c1808696688db9bf6f20253e5d05b5Mark Andrews the connection.
fb9ef31fed818384ef8997f2dc5f27252c6f767eEvan Hunt * TCP connections now are kept on three lists, one for active
fb9ef31fed818384ef8997f2dc5f27252c6f767eEvan Hunt connections, one for listening connections, and one for
823ccd1f02802966395d58c916e9f988320fd6eeEvan Hunt connections that are in TIME-WAIT. This greatly speeds up the fast
823ccd1f02802966395d58c916e9f988320fd6eeEvan Hunt timeout processing for sending delayed ACKs.
b6fa637fc8c92f42a21e6f97259598968717af3dEvan Hunt * TCP now provides proper feedback to the application when a
b6fa637fc8c92f42a21e6f97259598968717af3dEvan Hunt connection has been successfully set up.
b6fa637fc8c92f42a21e6f97259598968717af3dEvan Hunt * More comments have been added to the code. The code has also been
ace5680c122ef239e64eec1120f13f5a7f087d79Mark Andrews somewhat cleaned up.
