ea035707b3 * Support the new {send,read}_data_no_buffer() protocol hooks to avoid
unnecessary data copies and waste of memory.
* Changed the storage backend to ring_buffer.

cdc00dadfc * Added optional {send,read}_data_no_buffer() hooks to the protocol
module interface. They directly operate on iovecs and thus allow
  protocols that don't need it to avoid the creation of a net_buffer.
* Adjusted the socket module to support the new hooks. If they are
  present, they will be chosen over the old hooks.

3134e71811 Also check whether the data pointers of provided userland iovecs are
actually pointing to userland. This saves checks in the net stack.

03298f9d20 * The WaitList now always notifies all waiters.
* In SendData(), TCP will now split the buffer into smaller parts if it
  can send data (ie. there is free space in the buffer queue left, but
  not enough to send the whole buffer, and the free space is more than
  the send low water mark of the socket).
* Both of these changes together let TCP now pass the "forwarding" test
  of the OpenSSH suite.

ancillary_data_container, now. One can just set the container on a

6f57d9d066 When creating a socket file descriptor fetch the SO_NONBLOCK value from
the socket first, so the FD open flags are in sync with that. Fixes
situations where a socket accept()ed from a non-blocking listener socket
wouldn't have O_NONBLOCK set.

042be52922 In Shutdown() pass an actual error code to notify(). B_OK is just
ignored. This fixes the hanging OpenSSH "multiplex" test. Save for the
"forwarding" test, which sometimes hangs due to a TCP bug, the complete
test suite passes, now.

0c615a01ae * Removed old mutex implementation and renamed cutex to mutex.
* Trivial adjustments of code using mutexes. Mostly removing the
  mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
  spinlock being held. The spinlock is released while waiting, of
  course. This function is useful in cases where the existence of the
  mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
  another team needs to be locked to use mutex_lock_threads_locked().
  Before it required a semaphore-based mutex implementation.

ee96aa8f6e * Replaced cutex::release_count by flags field. It is only one thread
that can unlock the mutex, so one bit is sufficient.
* Added cutex_init_etc() which has an additional "flags" parameter.
  The only specifyable flag is CUTEX_FLAG_CLONE_NAME, which causes the
  function to strdup() the given name and free() its copy in
  cutex_destroy().
* cutex_destroy() does now unblock waiting threads.

63368af591 * As Ingo pointed out to me earlier, TCP could now delete its socket too early
when using the shutdown() command.
* If TCP no longer needs a socket, it will now set the flag FLAG_DELETE_ON_CLOSE;
  when the socket is closed from the upper layers, it will set the FLAG_CLOSED
  flag - and only if both are set, TCP will now delete the socket itself on
  receive.
* This fixes bug #2189.

8562499f44 * Introduced a new locking primitive I called "cutex" (sorry for the
name, couldn't resist :-P). It's semantically equivalent to a mutex,
  but doesn't need a semaphore (it uses thread blocking and a simple
  queue instead). Initialization can't fail. In fact it is ready to use
  without initialization when living in the bss segment, also in the
  early boot process. It's as fast as a benaphore in cases of low lock
  contention, and faster otherwise.  Only disadvantage is the higher
  immediate memory footprint of 16 bytes.
* Changed how the "thread" and "threads" debugger commands list the
  objects they are waiting for. Cutexes are also included.

4e6b38af6c Following Axel's suggestions:
* Added data_node::flags field and currently only flag
  DATA_NODE_READ_ONLY, indicating that the node is read-only (i.e.
  a clone). If set, the node won't have any header or tail space. Not
  being able to write to it is not yet enforced, though.
* Moved data_node::tail_space to data_header.
* Removed data_node:used_header_space/own_header_space.

the selecting thread, which has obviously no effect.

  This removes a race condition when concurrent threads would notify at
  the same time.

6aede71c0c Resolve a TODO and fix another ancient bug, #386. Print Screen is now handled
by BWindow, no longer by the app_server. This should stop the "screen freeze"
effect.

This adds a dependency on libpng.so and libz.so to libbe.so. The same
dependencies and the PNGDump code added here can be removed from the
app_server. I am just waiting for a code review of this before doing that.

This implementation still does not give the client a chance to handle it
differently.

9981c81f8b Fixed a race condition between select_fd() and close(). Since
select_fd() first added the select info to the IO context and then
called select() on the descriptor, a close() called at the same time
could already deselect the events and close the descriptor before
select_fd() was done with select(). select_fd() does now keep an own
open reference while selecting the events and add the select info
afterwards to the IO context (if the FD is still current).

e9488bd9e6 * Removed bogus select notifications in socket_close(). This is really
not necessary, since the VFS makes sure (or should at least) that all
  events are deselected when close() is called. ~0 isn't a valid event
  anyway.
* Removed delete_select_sync_pool() in socket_free(). It's not
  necessary, since the select_sync_pool is auto-destroyed when the last
  event has been deselected (which the VFS should take care of).

  condition, and it's deleted only once.

0b69689a18 * Fixed free_data_header_space(). It would increase the header space
although it put the freed space in the free list. Alternating
  invocations of alloc_...() and free_...() would thus increase the
  header space unboundedly.
* Unified the way a data_header and data_node access the header space.
  Originally data_header::data_space and data_node::header_space had to
  be kept in sync, which some functions failed to do. Introduced a
  header_space structure, which is located in data_header and referenced
  by data_node, so that accessing it either way does always keep both
  structures in sync.
* Removed the special handling for the data node created with a buffer.
  Since remove_{header,trailer}() and trim() could remove it without
  knowing, the last reference to the first data header would be freed
  prematurely, causing operations on freed memory, and in the end a
  second free which screwed the object cache's free list. This crashed
  Haiku e.g. when running OpenSSH's "forwarding" test. Now the first
  created node is just a node like any other. It's allocated in the data
  header, too.
* Changed the mechanism how data nodes are allocated. Now they will
  always be allocated on a header associated with the buffer for which
  they are created. This fixes a race condition when freeing them. They
  would otherwise modify the free list of a header which might be
  accessed by another thread at the same time (added a TODO explaining
  how the old code could possibly be fixed). Also squashed several
  TODOs related to running out of header space when allocating a node.
  If the buffer runs out of header space, it will simply allocate a new
  header, now.
* Dealt with some TODOs regarding reverting the buffer to its previous
  state when running out of memory after allocating a few nodes.
* Added several TODOs.

still cause a double free. Checked in mainly for Axel's reading
pleasure. :-)
