interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.

udp_unreachable finally work as intended.

do not get the '_' prefix, only private ones do).
* Added a "peek" argument to SocketStatus() (and generally renamed "clone" to
"peek" where it made sense).
* Implemented the base version of SocketStatus() to return the actual socket
error. This enables returning ICMP errors back to the socket user.
* Other minor cleanup.

upper layers.

upper layers: you use the store_header() function to mark the header you want
to preserve. All subsequent remove_header() calls won't claim the actual
data, but only move the node start around.
* This header can then be restored by restore_header(). However, a call to
prepend_data() will destroy the stored header. Also, if remove_header() cuts
off a whole node, restoring the header won't succeed anymore.
* Discarded the no longer needed net_buffer::network_header field.
* Also discarded the hoplimit field which temporarily breaks the IPv6 build
until Atis reworks it.
* IPv4 now also dumps the IP header in the send path if debug output is enabled.
* icmp_error_reply() might be called so early that the net_buffer's addresses
do not point to the reply address; this is now detected, and the addresses are
taken out of the IP header in that case.
* Improved dumping the net_buffer to also include its address, and flags.

instead of always returning B_OK.
* deliver_multicast() now takes the protocol restriction of a raw socket into
account.
* raw_receive_data() now correctly returns whether a buffer was delivered (due
to the protocol restriction, this wasn't the case before).
* ipv4_receive_data() leaked all multicast buffers.
* Some minor cleanup.

much all of it because of the countless bugs and problems it had, it still
shares the same architectural problems of introducing a domain dependent
error mechanism to the upper layers, and needing the
net_buffer::network_header hack. This I will rework later.
* net_buffer's append_size(), and prepend_size() will now gracefully handle
buffers without a data node.

* added Jenkin's hash algorith
* minor changes in existing IPv4 code - cleanup function
ipv4_get_loopback_address(), written by myself
* add tests: raw, udp, tcp/udp, mullicast sender
* add 'hoplimit' field in struct net_buffer
- TODO: this is just a hack, more generic approach would be better.
* add 'receive_data' function pointer in

* Therefore, enabled all supported devices for the rtl81xx driver.
* Made the rtl81xx driver actually work by adding the missing PHYs - it doesn't
use the same PHYs as the rtl8139 driver. Imported the rgephy.c|h from FreeBSD

Applied patch for #5209 by oruizdorantes for usb_asix, do the same for usb_davicom.
Will eventually rework it in order to remove duplicated IDs list.
The usb_serial driver also needs the same optimization,

usb_serial is not yet included in haiku image neither ready (no tty module), there is less user experience immediate gain...

* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/

- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

BBufferConsumer::BufferReceived() cannot know whom to send the "buffer is
late" notification (unless we only have a single input). To solve this, the
media_header now contains extra fields that can be used to create a
media_source object.
* Unfortunately, BBufferProducer::SendBuffer() cannot know the output either in
case there is more than one. Hence, I deprecated the existing SendBuffer()
call and moved it into "private" - IOW old sources using it won't compile
anymore under Haiku.
* I introduced a new SendBuffer() variant that also gets the media_source as
argument.
* Updated all sources (that are part of the image) to use the new variant.
* Removed some purposely commented out code in the audio mixer.
* Implemented late buffer notification, as well as late buffer handling in the
audio mixer; this is a bit of work in progress, so the debug output is left
in there.

certain conditions indicate that we might deal with a fixed 512 bytes MBR on
a non 512 byte block size medium. One condition is that at least one partition
had to be shrunk to fit the available size (which usually happens with larger

if it didn't improve the situation it is reverted again. This is mostly a

multiple blocks at a time which it doesn't do as it always only returns one
block (and actually completely ignores the provided offset and length).
It only didn't crash after that because it would in the end always only memcpy
length >> block shift bytes which ends up being pretty small in most cases.
Since it does block wise mapping it can't do multiple blocks anyway, and really
using the block cache for this is all wrong because this should really use a
file map to resolve the block mapping and then use the file cache instead.
Still this at least gets it working. Beware though that protected DVD content
will make the block cache panic, as reading these blocks without prior setting
the drive up correctly will fail (the drive will stall the reads).

needs to be or'ed to the address specification), "uncached" is assumed.
* Set the memory type for the "BIOS" and "DMA" areas to write-back. Not sure, if
that's correct, but that's what was effectively used on my machines before.
* Changed x86_set_mtrrs() and the CPU module hook to also set the default memory
type.
* Rewrote the MTRR computation once more:
- Now we know all used memory ranges, so we are free to extend used ranges
into unused ones in order to simplify them for MTRR setup.
- Leverage the subtractive properties of uncached and write-through ranges to
simplify ranges of any other respectively write-back type.
- Set the default memory type to write-back, so we don't need MTRRs for the
RAM ranges.
- If a new range intersects with an existing one, we no longer just fail.
Instead we use the strictest requirements implied by the ranges. This fixes
#5383.
Overall the new algorithm should be sufficient with far less MTRRs than before
(on my desktop machine 4 are used at maximum, while 8 didn't quite suffice
before). A drawback of the current implementation is that it doesn't deal with
the case of running out of MTRRs at all, which might result in some ranges
having weaker caching/memory ordering properties than requested.

Unset() the header in Allocate() before calling it. This fixes bug #5410.
* CachedNode::Allocate() does not need to revert its changes; the transaction
will take care of that. However, BPlusTree::fHeader is currently not correctly
maintained if a transaction fails (working on that now).

a copy of its structure. CachedNode is only used to write to the header, now.
This should cause the block_cache to no longer have any referenced blocks
outside of any I/O.
* Coding style cleanup.

bytes restriction is only a soft limit. This fixes stalling TCP connections
because everything received would be out of window once this happened.
* Added a TODO to look into TCP's window management - it doesn't seem to be
right.
* Fixed build with tracing turned on.
* Made the fNumber member of tcp_sequence private.

* Added vm_clear_page_mapping_accessed_flags() and
vm_remove_all_page_mappings_if_unaccessed(), which combine the functionality
of vm_test_map_activation(), vm_clear_map_flags(), and
vm_remove_all_page_mappings(), thus saving lots of calls to translation map
methods. The backend is the new method
VMTranslationMap::ClearAccessedAndModified().
* Started to make use of the cached page queue and changed the meaning of the
other non-free queues slightly:
- Active queue: Contains mapped pages that have been used recently.
- Inactive queue: Contains mapped pages that have not been used recently. Also
contains unmapped temporary pages.
- Modified queue: Contains unmapped modified pages.
- Cached queue: Contains unmapped unmodified pages (LRU sorted).
Unless we're actually low on memory and actively do paging, modified and
cached queues only contain non-temporary pages. Cached pages are considered
quasi free. They still belong to a cache, but since they are unmodified and
unmapped, they can be freed immediately. And this is what
vm_page_[try_]reserve_pages() do now when there are no more actually free
pages at hand. Essentially this means that pages storing cached file data,
unless mmap()ped, no longer are considered used and don't contribute to page
pressure. Paging will not happen as long there are enough free + cached pages
available.
* Reimplemented the page daemon. It no longer scans all pages, but instead works
the page queues. As long as the free pages situation is harmless, it only
iterates through the active queue and deactivates pages that have not been
used recently. When paging occurs it additionally scans the inactive queue and
frees pages that have not been used recently.
* Changed the page reservation/allocation interface:
vm_page_[try_]reserve_pages(), vm_page_unreserve_pages(), and
vm_page_allocate_page() now take a vm_page_reservation structure pointer.
The reservation functions initialize the structure -- currently consisting
only of a count member for the number of still reserved pages.
vm_page_allocate_page() decrements the count and vm_page_unreserve_pages()
unreserves the remaining pages (if any). Advantages are that reservation/
unreservation mismatches cannot occur anymore, that vm_page_allocate_page()
can verify that the caller has indeed a reserved page left, and that there's
no unnecessary pressure on the free page pool anymore. The only disadvantage
is that the vm_page_reservation object needs to be passed around a bit.
* Reworked the page reservation implementation:
- Got rid of sSystemReservedPages and sPageDeficit. Instead
sUnreservedFreePages now actually contains the number of free pages that
have not yet been reserved (it cannot become negative anymore) and the new
sUnsatisfiedPageReservations contains the number of pages that are still
needed for reservation.
- Threads waiting for reservations do now add themselves to a waiter queue,
which is ordered by descending priority (VM priority and thread priority).
High priority waiters are served first when pages become available.
Fixes#5328.
* cache_prefetch_vnode(): Would reserve one less page than allocated later, if
the size wasn't page aligned.

general "flags" parameter. It encodes the target state of the page -- so
that the page isn't unnecessarily put in the wrong page queue first -- a
flag whether the page should be cleared, and one to indicate whether the
page should be marked busy.
* Added page state PAGE_STATE_CACHED. Not used yet.

flag. The obvious advantage is that one can still see what state a page is in
and even move it between states while being marked busy.
* Removed the vm_page::is_dummy flag. Instead we mark marker pages busy, which
in all cases has the same effect. Introduced a vm_page_is_dummy() that can
still check whether a given page is a dummy page.
* vm_page_unreserve_pages(): Before adding to the system reserve make sure
sUnreservedFreePages is non-negative. Otherwise we'd make nonexisting pages
available for allocation. steal_pages() still has the same problem and it
can't be solved that easily.
* map_page(): No longer changes the page state/mark the page unbusy. That's the
caller's responsibility.

memory and page reservation functions have a new "priority" parameter that
indicates how deep the function may tap into that reserve. The currently
existing priority levels are "user", "system", and "VIP". The idea is that
user programs should never be able to cause a state that gets the kernel into
trouble due to heavy battling for memory. The "VIP" level (not really used
yet) is intended for allocations that are required to free memory eventually
(in the page writer). More levels are thinkable in the future, like "user real
time" or "user system server".
* Added "priority" parameters to several VMCache methods.
* Replaced the map_backing_store() "unmapAddressRange" parameter by a "flags"
parameter.
* Added area creation flag CREATE_AREA_PRIORITY_VIP and slab allocator flag
CACHE_PRIORITY_VIP indicating the importance of the request.
* Changed most code to pass the right priorities/flags.
These changes already significantly improve the behavior in low memory
situations. I've tested a bit with 64 MB (virtual) RAM and, while not
particularly fast and responsive, the system remains at least usable under high
memory pressure.
As a side effect the slab allocator can now be used as general memory allocator.
Not done by default yet, though.
