network/stack: Add back a #pragma mark.

network/stack: De-templatize base_fifo methods.

Following the removal of the "Fifo" class, they
do not need to be templated anymore.

network/stack: Remove unused "Fifo" class.

Its declarations were moved from another header to this file
in 2008, with a comment in the commit message and a TODO here
questioning whether it was needed for anything. In the 15 years
since then, nothing has used it.

network/stack: Return EOPNOTSUPP when unhandled flags are specified.

This method is invoked directly in some protocols, e.g. L2cap (Bluetooth.)

trim: Added is_called_via_syscall() function.

* And use it in get_trim_data_from_user(), formerly known as copy_*().
* This fixes differentiating between user and kernel buffers.

Fix #9148 and probably #9128.

uninit_timers() needs to wait for the timer thread to exit before
deleting the timer mutex.

Fixed up network stack and drivers for x86_64.

* Various compilation fixes.
* Fixes to the FreeBSD compatibility layer (from comparing the x86-
specific bits with the equivalent amd64 sources in FreeBSD).
* Compile all the Ethernet drivers except for sis900 and wb840, these
require a bit more work to fix (will file a ticket soon). Tested
ipro1000 and rtl81xx, no issues.

Merged the signals branch into trunk, with these changes:
* The team and thread kernel structures have been renamed to Team and Thread
respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
private kernel headers are included that are no longer C compatible.

Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).

* Make sure the SIOCGIFCONF never returns an address with an address length
smaller than sizeof(sockaddr). This fixes a compatibility issue with other
platforms - portable software often assumes that the amount of bytes to
add to an ifreq structure is the larger amount between sizeof(ifreq), and
basically what the _SIZEOF_ADDR_IFREQ() macro returns, instead of always
relying on that macro.
* Renamed UserBuffer::Copy() to Push, ConsumedAmount() to BytesConsumed(),
added Pad() method.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37927 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The "net_timer" command was never removed, causing sort_debugger_commands()
to hang when entering KDL, after having unloaded the stack.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30197 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added TRACE macro to see what timers are set/cancelled.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30166 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a is_timer_running() function.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27631 a95241bf-73f2-0310-859d-f6bbb57e9c96

* wait_for_timer() now returns a status code.
* wait_for_timer() now detects if it has been called from within the timer
execution thread, and will return in error instead of waiting for itself
forever. This fixes bug #2682.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27620 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The timer thread accessed a timer (to delete the TIMER_IS_RUNNING flag) after
it had been removed from the list. Now, I removed the flag again (but kept
the flags field for now), and solved in a way that doesn't have this problem.
* This might have a positive effect on #2682.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27574 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a net_timer::flags field, and used it to implement the new
wait_for_timer() function.
* Moved the internal Fifo class into utility.cpp - we should probably just
remove it again.
* Fixed uninit_timers() so that it would even work in combination with the
timer thread if there are timers left to be scheduled.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26980 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced all instances of benaphores in the kernel code by mutexes.
* Removed kernel benaphores.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25690 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed THREAD_FLAGS_IOCTL_SYSCALL to THREAD_FLAGS_SYSCALL,
syscall_restart_ioctl_is_restarted() to syscall_restart_is_restarted,
IoctlSyscallFlagUnsetter to SyscallFlagUnsetter, and
IoctlSyscallRestartWrapper to SyscallRestartWrapper, as they are no
longer only used for ioctl().
* Removed unused syscall_restart_ioctl_handle_post().
* Made SyscallRestartWrapper a lot fancier. Instead of storing a
reference to the result value, it stores the value itself, and it
features all the interesting operators that make it appear like that
value. This simplifies the use of the class quite a bit.
* THREAD_FLAGS_SYSCALL is now set for all socket function and the
read[v](), write[v]() syscalls.
* Added is_syscall() function and net_stack hook to the net stack.
* Removed "kernel" parameter from all net_stack_interface and net_socket
module hooks. They aren't need any longer, since is_syscall() can be
used instead.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24914 a95241bf-73f2-0310-859d-f6bbb57e9c96

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.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23984 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a "net_timer" KDL command that dumps all network timers.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22923 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.

packet capture sockets are now properly notified when the device is going down.

- modified LinkProtocol::ReadData() a bit so it can safely react to external changes such as the device being monitored going down.
- fixed an issue in invalidate_routes() where in some cases the default route was being kept.
- fixed another issue related with the fifo implementation, the notifier semaphore was being created with count of 1, instead of 0.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20622 a95241bf-73f2-0310-859d-f6bbb57e9c96

Prepared net_device_monitor to accept device removal events.

- Introduced public net_device_monitor.
- Changed the link protocol to maintain a lock per instance instead of inside the FIFO. Now all of the link instance data is protected.
- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20614 a95241bf-73f2-0310-859d-f6bbb57e9c96

introduced fifo_socket_enqueue_buffer which clones the buffer, enqueues it to the fifo and notifies the socket.

- changed the link, ipv4 and udp modules to use fifo_socket_enqueue_buffer

current_bytes wasn't being updated on fifo_dequeue_buffer(). Patch by Hugo Santos.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20454 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added two more utility functions to the timer service:
* cancel_timer() cancels a timer, and returns true if the timer was running
* is_timer_active() determines if the timer is currently running or not.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19393 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Small optimization for set_timer(): now only removes the timer from the list
if it won't be added anymore.
* Small fix for set_timer(): now set the timer->due field back to 0 when a
timer is removed - this prevented a timer from being correctly readded later
(possible crash)!
* net_buffer's append_cloned_data() now does some more checks to prevent unnecessary
work and detect wrong arguments.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19375 a95241bf-73f2-0310-859d-f6bbb57e9c96

Small optimization of the timer mechanism: the timeout is no longer updated
if not really necessary; ie. you can now add timers without an extra performance
hit if it's not really required.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19354 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented select support for sockets and notifications, not yet tested, though;
this closes ticket #811.
* Added notification support to IPv4 and UDP.
* Implemented reading out SO_ERROR.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19017 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed ppp_up and pppcontrol from the image for now.
