though. Please review.

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.

* 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.

table. This is not necessary, but allows for a better solution fo how to
lock the IO context of another team.

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.

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.

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25276 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
* Changed select_info::events to vint32. It is now updated atomically.
This removes a race condition when concurrent threads would notify at
the same time.

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25269 a95241bf-73f2-0310-859d-f6bbb57e9c96
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25266 a95241bf-73f2-0310-859d-f6bbb57e9c96
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25265 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the pointers const.
* Changed how the ARP module maintains its arp_entry::request_buffer: it
now uses the atomic_pointer*() functions to make sure there is no race
condition, and it's deleted only once.
* Getting an ARP entry would return uninitialized data, if the entry hadn't
been resolved yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25263 a95241bf-73f2-0310-859d-f6bbb57e9c96
64-bit safe version of atomic_test_and_set() for pointers:
atomic_pointer_test_and_set().
* The VFS is now using this function (it's not used anywhere else in the
kernel this way).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25260 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

arp_update_entry(). While arp_timer() was sending the last request
arp_update_entry() could be called (caused by an incoming reply) and
free the request buffer, which arp_timer() would free a moment later
again. The problem is not completely solved, since a duplicate reply can
still cause a double free. Checked in mainly for Axel's reading
pleasure. :-)

sPageLock. This could easily mess up the page queue.

block would be incorrectly addressed when allocating a stream - this could
cause random blocks to be overwritten, and therefore could cause many sorts
of problems.

new semantics of those other macros in there.

closed connection.

this (seems to be what R5 BStatusBar does):
* combine the "trailing text" with the "trailing label" and truncate the
resulting string on the left side according to the width of the entire
control
* combine the "label" with the "text" and truncate that on the right side
according to the space left by the right hand text.
-> No more overlaps (theoretically, in practise there are still overlaps
because our BFont::TruncateString() does not respect the width in some
situations.)
* Changed _SetTextData() accordingly, it is not used anymore for the
label and trailing label, and could therefor be simplified a little.
* fixed _BarFrame() to not return fractional coords, which could sometimes
leave a dirty line of pixels.

fixes the "endless discussions" when closing a local connection - only
happened on a simultaneous close.
* A FIN in TIME_WAIT now updates the time-wait timer, as required by the
TCP specification.
* Entering TIME_WAIT now cancels all connection timers. We might want to
think about putting time wait connections into a separate hash, and delete
the socket early on.
* Added tracing support for send/receive, timers, and state changes.
* Cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25236 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implement "close" command that actively closes the server socket, or does
an simultaneous close. Even though this triggers an "endless conversation"
between two time-wait endpoints on Haiku, it works fine in the shell.

now used from various places that previously did not cancel all timers
they should have.
* When a connection moves to the CLOSED state, it should cancel all timers;
this prevents from sending a reset at the end of a connection.
* If the persist/delayed acknowledge timers were canceled too late, they might
still have tried to send something (which would eventually cause a reset
sent to the peer).
* Follow RFC 1337 with respect to time wait assassination prevention (ie.
we now ignore resets from peers in time wait state).
* _SegmentReceived() must not check the sequence of a time wait connection;
it prevented sending a reset when that was due (a new connection request
would time out, instead of fail immediately).
* Also, that method must never be called in the LISTEN or SYNCHRONIZE_SENT
states, so we don't need to check for those.
* We don't have to wait in Close() until the connection is actually closed -
removed a TODO. TCP should handle this internally.
* Renamed _ShutdownEgress() to _Shutdown().

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).

* Added "mode" parameter to set_paranoia_check(), which specifies
whether the check is supposed to already exist/not exist yet. This
allows for, as it turns out, very useful additional tests. Added
{ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"
parameter.
* PARANOIA_SLOT_COUNT was accidentally redefined in the source file.
* Fixed remove_paranoia_check(). It didn't remove anything.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25207 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.
