a82212bd36e1074408974b466798b9966bbaf49bvboxsync word-length, storage sizes and alignment. See the mailing lists for
a82212bd36e1074408974b466798b9966bbaf49bvboxsync problems with exoteric (/DSP) architectures showing these problems.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync We still have to fix some of these issues neatly.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TODO: the ARP layer is not protected against concurrent access. If
a82212bd36e1074408974b466798b9966bbaf49bvboxsync you run from a multitasking OS, serialize access to ARP (called from
a82212bd36e1074408974b466798b9966bbaf49bvboxsync your network device driver and from a timeout thread.)
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TODO: the PPP code is broken in a few ways. There are namespace
a82212bd36e1074408974b466798b9966bbaf49bvboxsync collisions on BSD systems and many assumptions on word-length
a82212bd36e1074408974b466798b9966bbaf49bvboxsync (sizeof(int)). In ppp.c an assumption is made on the availability of
a82212bd36e1074408974b466798b9966bbaf49bvboxsync a thread subsystem. Either PPP needs to be moved to contrib/ports/???
a82212bd36e1074408974b466798b9966bbaf49bvboxsync or rearranged to be more generic.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync for bugs and performance issues. Frequent system calls (e.g. sys_mbox_fetch)
a82212bd36e1074408974b466798b9966bbaf49bvboxsync slooow things down considerably.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
a82212bd36e1074408974b466798b9966bbaf49bvboxsync access and added pbuf_alloc() return value checks.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
a82212bd36e1074408974b466798b9966bbaf49bvboxsync now handled by the checksum routine properly.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * pbuf.c: Fix alignment; pbuf_init() would not work unless
a82212bd36e1074408974b466798b9966bbaf49bvboxsync pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)

a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-12-15 Christiaan Simons
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * inet.c: Disabled the added summing routine to preserve code space.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync Added Curt McDowell's optimized checksumming routine for future
a82212bd36e1074408974b466798b9966bbaf49bvboxsync inclusion. Need to create test case for unaliged, aligned, odd,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync even length combination of cases on various endianess machines.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-12-09 Christiaan Simons
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * inet.c: Rewrote standard checksum routine in proper portable C.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-11-25 Christiaan Simons
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync u32_t, s32_t typedefs. This solves most debug word-length assumes.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * inet.c: Fixed unaligned 16-bit access in the standard checksum
a82212bd36e1074408974b466798b9966bbaf49bvboxsync routine by Peter Jolasson.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp_{out|in}.c: Applied patch fixing unaligned access.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * udp.c: UDP pcb->recv() was called even when it was NULL.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.*: Disabled multiple packets on the ARP queue.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync This clashes with TCP queueing.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.*: Fixed race condition from ARP request to ARP timeout.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync Halved the ARP period, doubled the period counts.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ETHARP_MAX_PENDING now should be at least 2. This prevents
a82212bd36e1074408974b466798b9966bbaf49bvboxsync the counter from reaching 0 right away (which would allow
a82212bd36e1074408974b466798b9966bbaf49bvboxsync too little time for ARP responses to be received).

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * dhcp.c: Decline messages were not multicast but unicast.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync Do not try hard to insert arbitrary packet's source address,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync etharp_query() now always DOES call ETHARP_TRY_HARD so that users
a82212bd36e1074408974b466798b9966bbaf49bvboxsync querying an address will see it appear in the cache (DHCP could
a82212bd36e1074408974b466798b9966bbaf49bvboxsync suffer from this when a server invalidly gave an in-use address.)
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
a82212bd36e1074408974b466798b9966bbaf49bvboxsync comparing network addresses (identifiers), not the network masks
a82212bd36e1074408974b466798b9966bbaf49bvboxsync themselves.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
a82212bd36e1074408974b466798b9966bbaf49bvboxsync IP address actually belongs to the network of the given interface.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(STABLE-1_1_0-RC1)

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync even if one is already pending, if the rcv_wnd is above a threshold
a82212bd36e1074408974b466798b9966bbaf49bvboxsync (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
a82212bd36e1074408974b466798b9966bbaf49bvboxsync delayed ACK in order to open the window if the stack is only receiving data.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.c: Make sure the first pbuf queued on an ARP entry
a82212bd36e1074408974b466798b9966bbaf49bvboxsync is properly ref counted.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
a82212bd36e1074408974b466798b9966bbaf49bvboxsync warnings about comparison.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * pbuf.c: Stopped compiler complaining of empty if statement
a82212bd36e1074408974b466798b9966bbaf49bvboxsync when LWIP_DEBUGF() empty. Closed an unclosed comment.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * tcp.c: Stopped compiler complaining of empty if statement
a82212bd36e1074408974b466798b9966bbaf49bvboxsync when LWIP_DEBUGF() empty.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * inet.c: Added a couple of casts to quiet the compiler.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync No need to test isascii(c) before isdigit(c) or isxdigit(c).

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.c: Removed spurious semicolon and added missing end-of-comment.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ethernetif.c Updated low_level_output() to match prototype for
a82212bd36e1074408974b466798b9966bbaf49bvboxsync netif->linkoutput and changed low_level_input() similarly for consistency.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
a82212bd36e1074408974b466798b9966bbaf49bvboxsync of raw_recv() in raw.h and so avoid compiler error.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * sockets.c: Added trivial (int) cast to keep compiler happier.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
a82212bd36e1074408974b466798b9966bbaf49bvboxsync the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.

a82212bd36e1074408974b466798b9966bbaf49bvboxsync Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
a82212bd36e1074408974b466798b9966bbaf49bvboxsync if an outgoing packet can be directly sent on the link, or perform
a82212bd36e1074408974b466798b9966bbaf49bvboxsync a copy-on-demand when necessary.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync The application can safely assume the packet is sent, and the RAM
a82212bd36e1074408974b466798b9966bbaf49bvboxsync is available to the application directly after calling udp_send()

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The packet buffer implementation is changed. The pbuf->ref counter
a82212bd36e1074408974b466798b9966bbaf49bvboxsync meaning has changed, and several pbuf functions have been
a82212bd36e1074408974b466798b9966bbaf49bvboxsync adapted accordingly.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * netif drivers have to be changed to set the hardware address length field

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP and UDP ->dest_* struct members where changed to ->remote_*.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * ntoh* macros are now null definitions for big endian CPUs.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.5.0) Changes since version 0.4.2
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ New features:

a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ Other changes:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Directory structure somewhat changed; the core/ tree has been
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.4.2) Changes since version 0.4.1

a82212bd36e1074408974b466798b9966bbaf49bvboxsync * In very intense situations, memory leakage could occur. This has
a82212bd36e1074408974b466798b9966bbaf49bvboxsync been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ Other changes:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Variables named "data" and "code" have been renamed in order to
a82212bd36e1074408974b466798b9966bbaf49bvboxsync avoid name conflicts in certain compilers.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Variable++ have in appliciable cases been translated to ++variable
a82212bd36e1074408974b466798b9966bbaf49bvboxsync since some compilers generate better code in the latter case.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.4.1) Changes since version 0.4
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ New features:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP: Connection attempts time out earlier than data
a82212bd36e1074408974b466798b9966bbaf49bvboxsync transmissions. Nagle algorithm implemented. Push flag set on the
a82212bd36e1074408974b466798b9966bbaf49bvboxsync last segment in a burst.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * UDP: experimental support for UDP-Lite extensions.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ Bugfixes:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP: out of order segments were in some cases handled incorrectly,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync and this has now been fixed. Delayed acknowledgements was broken
a82212bd36e1074408974b466798b9966bbaf49bvboxsync in 0.4, has now been fixed. Binding to an address that is in use
a82212bd36e1074408974b466798b9966bbaf49bvboxsync now results in an error. Reset connections sometimes hung an
a82212bd36e1074408974b466798b9966bbaf49bvboxsync application; this has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Checksum calculation sometimes failed for chained pbufs with odd
a82212bd36e1074408974b466798b9966bbaf49bvboxsync lengths. This has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * API: a lot of bug fixes in the API. The UDP API has been improved
a82212bd36e1074408974b466798b9966bbaf49bvboxsync and tested. Error reporting and handling has been
a82212bd36e1074408974b466798b9966bbaf49bvboxsync improved. Logical flaws and race conditions for incoming TCP
a82212bd36e1074408974b466798b9966bbaf49bvboxsync connections has been found and removed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Memory manager: alignment issues. Reallocating memory sometimes
a82212bd36e1074408974b466798b9966bbaf49bvboxsync failed, this has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Generic library: bcopy was flawed and has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ++ Other changes:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * API: all datatypes has been changed from generic ones such as
a82212bd36e1074408974b466798b9966bbaf49bvboxsync ints, to specified ones such as u16_t. Functions that return
a82212bd36e1074408974b466798b9966bbaf49bvboxsync errors now have the correct type (err_t).
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * General: A lot of code cleaned up and debugging code removed. Many
a82212bd36e1074408974b466798b9966bbaf49bvboxsync portability issues have been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The license was changed; the advertising clause was removed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * C64 port added.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
a82212bd36e1074408974b466798b9966bbaf49bvboxsync Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
a82212bd36e1074408974b466798b9966bbaf49bvboxsync fixing bugs!
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.4) Changes since version 0.3.1
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Memory management has been radically changed; instead of
a82212bd36e1074408974b466798b9966bbaf49bvboxsync allocating memory from a shared heap, memory for objects that are
a82212bd36e1074408974b466798b9966bbaf49bvboxsync rapidly allocated and deallocated is now kept in pools. Allocation
a82212bd36e1074408974b466798b9966bbaf49bvboxsync and deallocation from those memory pools is very fast. The shared
a82212bd36e1074408974b466798b9966bbaf49bvboxsync heap is still present but is used less frequently.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The memory, memory pool, and packet buffer subsystems now support
a82212bd36e1074408974b466798b9966bbaf49bvboxsync 4-, 2-, or 1-byte alignment.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * "Out of memory" situations are handled in a more robust way.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Stack usage has been reduced.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Easier configuration of lwIP parameters such as memory usage,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync TTLs, statistics gathering, etc. All configuration parameters are
a82212bd36e1074408974b466798b9966bbaf49bvboxsync now kept in a single header file "lwipopts.h".
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The directory structure has been changed slightly so that all
a82212bd36e1074408974b466798b9966bbaf49bvboxsync architecture specific files are kept under the src/arch
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Error propagation has been improved, both in the protocol modules
a82212bd36e1074408974b466798b9966bbaf49bvboxsync and in the API.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The code for the RTXC architecture has been implemented, tested
a82212bd36e1074408974b466798b9966bbaf49bvboxsync and put to use.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Bugs have been found and corrected in the TCP, UDP, IP, API, and
a82212bd36e1074408974b466798b9966bbaf49bvboxsync the Internet checksum modules.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Bugs related to porting between a 32-bit and a 16-bit architecture
a82212bd36e1074408974b466798b9966bbaf49bvboxsync have been found and corrected.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The license has been changed slightly to conform more with the
a82212bd36e1074408974b466798b9966bbaf49bvboxsync original BSD license, including the advertisement clause.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.3.1) Changes since version 0.3
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Fix of a fatal bug in the buffer management. Pbufs with allocated
a82212bd36e1074408974b466798b9966bbaf49bvboxsync RAM never returned the RAM when the pbuf was deallocated.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP congestion control, window updates and retransmissions did not
a82212bd36e1074408974b466798b9966bbaf49bvboxsync work correctly. This has now been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Bugfixes in the API.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.3) Changes since version 0.2
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * New and improved directory structure. All include files are now
a82212bd36e1074408974b466798b9966bbaf49bvboxsync kept in a dedicated include/ directory.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * The API now has proper error handling. A new function,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync netconn_err(), now returns an error code for the connection in
a82212bd36e1074408974b466798b9966bbaf49bvboxsync case of errors.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Improvements in the memory management subsystem. The system now
a82212bd36e1074408974b466798b9966bbaf49bvboxsync keeps a pointer to the lowest free memory block. A new function,
a82212bd36e1074408974b466798b9966bbaf49bvboxsync mem_malloc2() tries to allocate memory once, and if it fails tries
a82212bd36e1074408974b466798b9966bbaf49bvboxsync to free some memory and retry the allocation.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Much testing has been done with limited memory
a82212bd36e1074408974b466798b9966bbaf49bvboxsync configurations. lwIP now does a better job when overloaded.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Some bugfixes and improvements to the buffer (pbuf) subsystem.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * Many bugfixes in the TCP code:
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - Fixed a bug in tcp_close().
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - The TCP receive window was incorrectly closed when out of
a82212bd36e1074408974b466798b9966bbaf49bvboxsync sequence segments was received. This has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - Connections are now timed-out of the FIN-WAIT-2 state.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - The initial congestion window could in some cases be too
a82212bd36e1074408974b466798b9966bbaf49bvboxsync large. This has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - The retransmission queue could in some cases be screwed up. This
a82212bd36e1074408974b466798b9966bbaf49bvboxsync has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - TCP RST flag now handled correctly.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - Out of sequence data was in some cases never delivered to the
a82212bd36e1074408974b466798b9966bbaf49bvboxsync application. This has been fixed.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - Retransmitted segments now contain the correct acknowledgment
a82212bd36e1074408974b466798b9966bbaf49bvboxsync number and advertised window.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync - TCP retransmission timeout backoffs are not correctly computed
a82212bd36e1074408974b466798b9966bbaf49bvboxsync (ala BSD). After a number of retransmissions, TCP now gives up
a82212bd36e1074408974b466798b9966bbaf49bvboxsync the connection.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP connections now are kept on three lists, one for active
a82212bd36e1074408974b466798b9966bbaf49bvboxsync connections, one for listening connections, and one for
a82212bd36e1074408974b466798b9966bbaf49bvboxsync connections that are in TIME-WAIT. This greatly speeds up the fast
a82212bd36e1074408974b466798b9966bbaf49bvboxsync timeout processing for sending delayed ACKs.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * TCP now provides proper feedback to the application when a
a82212bd36e1074408974b466798b9966bbaf49bvboxsync connection has been successfully set up.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync * More comments have been added to the code. The code has also been
a82212bd36e1074408974b466798b9966bbaf49bvboxsync somewhat cleaned up.
a82212bd36e1074408974b466798b9966bbaf49bvboxsync(0.2) Initial public release.
