- IPv4 now assumes the addresses it is supplied in send_routed_data are already the appropriate ones.
- made the Data(), operator* and operator-> methods in NetBufferFieldReader const so we can use them in the same expression as the constructor.
- fixed an issue with UDP where the wrong source address could be used in the calculating the checksum.
- changed ipv4_print_address to use the more common 0.0.0.0 format.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20660 a95241bf-73f2-0310-859d-f6bbb57e9c96
- introduced base NetBufferFieldReader which deals with obtaining a continuguous field to deal with.
- renamed Detach() to Sync() to better express the fact that we may be writing to the buffer.
- Fixed IPv4's and ICMP's checksum calculation as it assumed the underlying header was contiguous.
- ICMP is now able to reply to ICMP Echo Requests which were split across data nodes.
- in split_buffer(), make sure we were able to trim() the new buffer before damaging the original one.

- and when in LISTEN, we should use the socket's connection queue size.

- 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

* The device interface list now uses class DoublyLinkedList instead of struct list.
* Implemented SIOC[SG]IFMEDIA for setting (not supported by any device yet), and
retrieving the device media information.
* Fixed a locking bug in list_domain_interfaces().
* Added new stack function device_link_changed() that should be called in case the
link state (media) changed.
* The ethernet device module now spawns a thread and will periodically check the media
state of all ethernet devices that support this (if any).
* Minor cleanup.

* Added a BSD-style if_media.h.

* New debugger command "find_page", which searches all page queues to
find out, which one a page is actually in.
* Solved nasty race condition between the page scrubber and
vm_page_allocate_page_run(): The page scrubber didn't mark the pages

although being assigned to a cache at the same time. This should
finally solve bug #1056.

possibility to initialize the AutoLocker without locking the object even
if it is unlocked yet. Especially in loops Lock()/Unlock() come handy

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break

the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new

add-ons accordingly and removed the syscall.
* Removed send_notification().

send_notification(). Now it has a chance to work. Note that
notify_listener() is obsolete. I would already have removed it, if
there weren't lots of FS implementations still using it (Hint!).

Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.

* vm_clone_area() now respects the source area's wiring and inherits it. This
should fix bug #1055.
* vm_cache::type is now duplicated in vm_area::cache_type - this allows looking
it up without having to lock a vm_cache_ref; this also solves a locking bug
in vm_unmap_pages() in this regard.

Basically, there was a pretty subtle race between the cpus in main where if the main cpu released the AP cpus and then before the AP cpus had a chance to run the boot cpu started creating the main thread (which causes smp ici messages to be created) the system would livelock, where the boot cpu waited forever for the AP cpu to acknowledge the ICI (for a TLB flush when creating the kernel stack).
Added smp_cpu_rendezvous(), used to synchronize all the cpus to a particular point, and used it a few times in main().
While i was at it i fixed another race that'll probably never happen, but what the hey. Make sure the kernel args are copied into kernel space by the main cpu before letting any other ones use it.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20269 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.

old interface is completely done in userland ATM.
It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).

need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.

* vm_area and vm_page now have a new field "mappings" where they will store lists
of vm_page_mapping structures. vm_page::ref_count is gone, as it's no longer
needed (it was never updated correctly, anyway).
* vm_caches now have a type field, ie. CACHE_TYPE_RAM for anonymous areas - this
makes the stores a bit less independent, but is quite handy in several places.
* Added new vm_map_page() and vm_unmap_pages() functions to be used whenever you
map in or unmap pages into/from an area. They don't do much more than handling
vm_page::wired_count correctly right now, though (ie. B_LAZY_LOCK is now working
as expected as well).
* Moved the device fault handler to vm_map_physical_memory(); it was not really
used as a fault handler, anyway.
* Didn't notice Ingo's changes to the I/O space region broke lock_memory(). It
now checks the type of the area that contains the memory, and doesn't lock
anymore if not needed which solves the problem in a platform independent way.
* Implemented lock_memory() and unlock_memory() for real: they now change the
vm_page::wired_count member to identify pages that shouldn't be paged out.
* vm_area_for() now uses vm_area_lookup() internally.
* Fixed various potential overflow conditions with areas that reach 0xffffffff.
* Creating anonymous areas with B_FULL_LOCK no longer causes vm_soft_fault()
to be called, instead, the pages are allocated and mapped (via vm_map_page())
directly.
* Removed the _vm_ prefix for create_area_struct() and create_reserved_area_struct().
* Fixed a bug in vm_page_write_modified() that would not have enqueued pages that
failed to be written to the modified queue again when needed.

* Renamed them, made everything static besides vm_allocate_early() (previous
vm_alloc_from_kernel_args()) which now allows you to specify a different
virtual than physical size, and therefore makes vm_alloc_virtual_from_kernel_args()
superfluous (which isn't exported anymore, and is now called allocate_early_virtual()).
* Enabled printing a stack trace on serial output on team crash - it doesn't hurt
for now, anyway.
* Cleanup.

* Renamed a few parameters of the FS module hooks:
- *file in the attribute functions to *vnode
- v to vnode
- I could barely restrain myself from renaming the "_*" parameters. I
understand this marks return parameters, but I'd prefer a nicer prefix
or suffix (that doesn't makes you think this is a private/internal
identifier) like "out", "ret", "return", "result", or something similar.
I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

Now two complete tss structures exist within the per-cpu structure. Instead
of having to create a seperate area per each one, initialize them in place.
Also, the old mechanism to getting all of the cpus to get initialized was
subtly broken, but still managed to work. Now, just force all the cpus to
initialize at boot, which makes the actual swapping of esp0 somewhat simpler.

for one quantum wasn't really a good idea, as this could get quite expensive for the thread
(depending on the system load, it might have taken a long time until the thread was scheduled
again, no matter what priority it was).
Also, calling thread_yield() in a loop would have taken 100% CPU time.
Now, we sort the thread into the queue as with any other thread, but we'll ignore it once.
This now guarantees an actual context switch, as well as a much fairer rescheduling policy
for threads calling that function.

at boot, per cpu, detect the cpu, pull down all the relevant cpuid bits and
save them into the per-cpu structure. Changed most of the code scattered here
and there that reads the cpuid to use a new api, x86_check_feature, which looks
at the saved bits.
Also changed the system_info stuff to read from these bits.
While i was at it, refreshed all the bits to be current.

this fixes bug #1005. As a result, the Disks icon will now appear in file panels
when you change that setting with a panel open.
* _ObserverList is now in the BPrivate namespace (and renamed to ObserverList).
* its BHandler map is now only temporarily used for handlers that do not belong to
a looper yet; when BHandler::SendNotices() is called, they will be transferred
into the BMessenger map.
* Invalid messengers are now removed from the map when encountered.
* Added TODO comments about a possible reference counting if a handler is added
twice to a list (right now, this will be ignored).
* All {Start|Stop}Watching() methods are now more or less safe to be used in low
memory situations (adding some items to the map can still throw an exception...).
* Renamed BHandler::InitData() to _InitData().
* Some refactoring and cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20029 a95241bf-73f2-0310-859d-f6bbb57e9c96
* we now always flush the TLBs after having unmapped some pages.
* vm_soft_fault() could traverse to a source cache while it was being collapsed
by vm_cache_remove_consumer() - this is now no longer possible as the latter
marks the cache as busy when doing so, and the former now tests this flag and
locks the cache (via the new fault_acquire_locked_source() function).
* if fault_acquire_locked_source() fails with B_BUSY, the current cache is locked
again, and tested again for the page - as it might have been moved upwards to it
with the destruction of its former source.
* The cache delivering the page for vm_soft_fault() is now locked until the end;
it can no longer go away before having actually mapped the page into the area.
* This also fixes the issue where pages would get lost as vm_soft_fault() put the
page in the active list, no matter if its cache still existed.
* Also, we now keep a reference of to a cache in case a dummy page is inserted; this
makes again sure that it doesn't go away during the execution of vm_soft_fault()
(which could even add this page to the free list...).
* divided vm_soft_fault() into several smaller functions which should make it much
more readable.
* Added a "cache_chain" KDL command that dumps the whole chain until the bottom
when giving a pointer to a vm_cache as parameter.
* now usually call vm_cache_acquire_ref() before map_backing_store(), even though
it shouldn't be really needed (I added it for debugging purposes).
* Some minor cleanup.
* NOTE: a major problem still persists: when removing a vm_cache, it's possible
that some of its pages are still mapped, and there is currently no mechanism
to get rid of these mappings! I've added TODO comments into vm_cache.c where
appropriate.

process group. This fixes bug #996.
* As a result, the process group stuff and wait_for_child() got much simpler;
get_death_entry() and update_wait_for_any() could go away completely.
* If a team goes away, all of its children are now "reparented" to the kernel team,
instead of the team's parent - this follows common implementations (and POSIX if
I understand it correctly), but not BeOS anymore. The OpenGroup Base says this
about this topic: "If a parent process terminates without waiting for all of its
child processes to terminate, the remaining child processes shall be assigned a
new parent process ID corresponding to an implementation-defined system process."
* We wait too long in wait_test_4 which at least puts us on par with Linux; see
comment in _user_setpgid().
