headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the
class to BOpenHashTable and changed the interface slightly so that HashTableLink
became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.

# 6f440aed 24-Apr-2009 Axel Dörfler <axeld@pinc-software.de>

* net_socket_module_info::acquire_socket() now returns whether or not the
socket could be acquired, ie. when its reference count is 0, it cannot be
acquired anymore. This requires the protocol to do proper locking, though.
* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.
* This fixes bug #2197.
* Minor cleanup.

# 11112327 07-Apr-2009 Axel Dörfler <axeld@pinc-software.de>

* Sockets now inherit from WeakReferenceable.
* This fixes the problem when a socket changes something with regards to its
parent.

* No longer leaks the EndpointManagers at unload.
* Now uses an array instead of a doubly linked list to find the endpoint
manager for a domain.
* No longer locks the endpoint managers during TCP processing, which actually
made all TCP input serialized.
* Minor cleanup.

# 276aa463 24-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Replaced the useless InitCheck() method in {Open,Multi}HashTable (it
always returned B_OK) by a Init() method, which sets the initial size
and returns an error, if that fails.
* Adjusted code using the classes accordingly. Replaced a few
InitCheck() methods in the network code by Init().

# 30a396ab 19-May-2008 Axel Dörfler <axeld@pinc-software.de>

* Made the endpoint manager wait on bind() if the existing connection is
local, and is about to close.
* This fixes several race conditions with the neon test suite that relied
on TCP sockets being gone after close, and their port being available again
(note, that is not what the TCP spec says, anyway, but it makes sense to
do so, since we already removed the time wait state for local connections).
* The endpoint manager is now using a mutex instead of a semaphore.
* TCPEndpoint::_Close() now notifies the senders/receivers instead of
_HandleReset().
* Besides ssl_closure(), all tests of the neon test suite seem to pass now.

# 5abeea69 29-Apr-2008 Axel Dörfler <axeld@pinc-software.de>

* Added tracing for binds and connects as well.
* Introduced the TCP_TRACING macro in tracing_config.h.
* Enlarged the default trace size to something a tiny bit useful (but still
acceptable for systems with little RAM).
* Cleanup.

# 42759f56 27-Apr-2008 Axel Dörfler <axeld@pinc-software.de>

* _BindToEphemeral() now remembers the last port it used, and tries a higher
one next. This should work around the problem Ingo observed with the OpenSSH
tests (not tested, though).
* The only TCP compliant fix for this problem would be to not enter time wait
for local connections at all (which I will do soon).
* Another work around other implementations use is to accept incoming
connections for time wait endpoints (the connection will then be replaced).
I'm not yet sure if I want that behaviour, though.
* Added tracing for unbinding endpoints (with stack trace) to investigate
another bug (sometimes closed connections aren't actually closed).

# 05849428 17-Feb-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

axeld + bonefish:
* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.

# 15ab0bcf 21-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

* int32_t, uint32_t are now of type "int", and no longer of type "long".
This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.

# 1d63ea33 18-Apr-2007 Hugo Santos <hugosantos@nowhere.fake>

some TCP performance improvements.

- support TCP fast retransmit/fast recovery.
- maintain the RTT average time and update the retransmit timeout accordingly.
- improvements to TCP Slow start / congestion avoidance.
- better handling of the retransmission timer.
- properly size segments taking the TCP options length into consideration.
- as an interim fix, update the SendQ/RecvQ sizes on Connect().

# f73dd74e 10-Apr-2007 Hugo Santos <hugosantos@nowhere.fake>

even more TCP fixage.

- don't try to remove spawned sockets from Endpoints hashtable.
- return B_WOULD_BLOCK (EAGAIN) when we time out in acquire_sem().
- use B_RELEASE_IF_WAITING_ONLY in the TCP WaitList.
- fixed a off by one issue in ReadData() which could result in more than needed iterations (and waiting).
- implemented prepending new buffers to a net_buffer.

# 7664bcb5 09-Apr-2007 Hugo Santos <hugosantos@nowhere.fake>

A couple more TCP fixes.

- ipv4_bind() was broken when binding to addresses not INADDR_ANY, as it wasn't copying the address to the socket, fixed.
- fixed a small issue in TCP's BindToEphemeral where the correct address might not have been bound to the socket.
- some assorted TCP wait lists fixes.
- fixed TCP's Connect() over the loopback interface, we might already be ESTABLISHED after _SendQueue() returns.
- fixed the amount of time we wait in TCP's Accept().

# a7edede4 09-Apr-2007 Hugo Santos <hugosantos@nowhere.fake>

fixed multiple TCP issues.

- Moved FIN handling to after Segment Text handling, it matches the RFC and fixes a possible issue with a user missing some final segment data when receiving a FIN.
- Fixed the FIN handling to better terminate connections (no more senseless chatter in the end with RSTs etc).
- When Bind()ing, set the socket address so a call to getsockname() gets the allocated port correctly.
- After reaching the ESTABLISHED state, try to wake all pending threads (still needs work).
- Corrected the maximum amount of time we wait in SendData() to respect socket->send.timeout.
- Now ReadData() behaves correctly in all possible states.
- There was a missing handling of MSG_DONTWAIT, fixed.
- Better internal handling of PSH.

# bbf8311d 07-Feb-2007 Axel Dörfler <axeld@pinc-software.de>

* Fixed a race condition between deletion of the endpoint and canceling its timers;
the timer functions could access invalid memory.
* The endpoint manager now panics if a bound endpoint is not in the hash.

Calmed down the networking stack a lot - since it basically works, there is no
reason to slow it down with debug output that much; this will also help investigating
some issues where you just aren't interested in most of the output.

# 9cbe6ce2 04-Dec-2006 Axel Dörfler <axeld@pinc-software.de>

Rewrote how bind() works:
* there are now two hash tables: one for connections, and one for ports
* the first one is used to find the endpoint for incoming connections
* the latter is used to check if the address to bind() to is still available
(incl. support for SO_REUSEADDR, and SO_REUSEPORT). Specialising an existing
socket is not allowed, though; wildcard sockets need to be started last.
* the TCPConnection class now has a pointer to the next endpoint with the
same port number - this list is scanned for the existing bound sockets
on that port.

* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.

# 15ab0bcf01ef7bd7323d9b2da55906bafbb40fd3 21-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

* int32_t, uint32_t are now of type "int", and no longer of type "long".
This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.

- support TCP fast retransmit/fast recovery.
- maintain the RTT average time and update the retransmit timeout accordingly.
- improvements to TCP Slow start / congestion avoidance.
- better handling of the retransmission timer.
- properly size segments taking the TCP options length into consideration.
- as an interim fix, update the SendQ/RecvQ sizes on Connect().

even more TCP fixage.

- don't try to remove spawned sockets from Endpoints hashtable.
- return B_WOULD_BLOCK (EAGAIN) when we time out in acquire_sem().
- use B_RELEASE_IF_WAITING_ONLY in the TCP WaitList.
- fixed a off by one issue in ReadData() which could result in more than needed iterations (and waiting).
- implemented prepending new buffers to a net_buffer.

A couple more TCP fixes.

- ipv4_bind() was broken when binding to addresses not INADDR_ANY, as it wasn't copying the address to the socket, fixed.
- fixed a small issue in TCP's BindToEphemeral where the correct address might not have been bound to the socket.
- some assorted TCP wait lists fixes.
- fixed TCP's Connect() over the loopback interface, we might already be ESTABLISHED after _SendQueue() returns.
- fixed the amount of time we wait in TCP's Accept().

fixed multiple TCP issues.

- Moved FIN handling to after Segment Text handling, it matches the RFC and fixes a possible issue with a user missing some final segment data when receiving a FIN.
- Fixed the FIN handling to better terminate connections (no more senseless chatter in the end with RSTs etc).
- When Bind()ing, set the socket address so a call to getsockname() gets the allocated port correctly.
- After reaching the ESTABLISHED state, try to wake all pending threads (still needs work).
- Corrected the maximum amount of time we wait in SendData() to respect socket->send.timeout.
- Now ReadData() behaves correctly in all possible states.
- There was a missing handling of MSG_DONTWAIT, fixed.
- Better internal handling of PSH.

the timer functions could access invalid memory.

Calmed down the networking stack a lot - since it basically works, there is no
reason to slow it down with debug output that much; this will also help investigating
some issues where you just aren't interested in most of the output.

Rewrote how bind() works:
* there are now two hash tables: one for connections, and one for ports
* the first one is used to find the endpoint for incoming connections
* the latter is used to check if the address to bind() to is still available
(incl. support for SO_REUSEADDR, and SO_REUSEPORT). Specialising an existing
socket is not allowed, though; wildcard sockets need to be started last.
* the TCPConnection class now has a pointer to the next endpoint with the
same port number - this list is scanned for the existing bound sockets
on that port.
