* It supports up to 256 different keys, which is equivalent of the solution

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

IoctlSyscallFlagUnsetter to SyscallFlagUnsetter, and
IoctlSyscallRestartWrapper to SyscallRestartWrapper, as they are no

* 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.

used instead.

- The net_stack driver is no longer used. Instead we have a kernel
module which is directly used by syscall implementations in the
kernel. I.e. we no longer tunnel those functions through ioctls, but
have normal syscalls.
- Removed the superfluous net starter module.
- Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
are no longer vnode based.
- Adjusted libnetwork (the socket function implementations)
accordingly.
- Adjusted netstat accordingly.
* Socket module:
- Implemented socketpair().
- Added "kernel" parameter to the control hook. Quite a few more hooks
would actually need the parameter, but I didn't change those yet,
since that would probably also require changes to the protocol
module interface.

This fixes a potential problem where a volume would be left marked dirty on
a clean reboot as reported by Vasilis; no harm would have been done to the
data on the volume, though (it would just replay a log entry that it didn't

* Unified the naming of the notifier/writer thread: renamed the thread to "block
notifier/writer", and the variable holding the thread ID to
sNotifierWriterThread.

listeners (that were added before notifying other listeners), so that BFS
could never free up space in the log. Now, it will only remove the listeners
it may remove. This fixes bug #2024.

also free the device info which it must not do, as this info is in fact just
a pointer to the device info of the raw node. Removing a raw device that had
partitions published therefore always lead into KDL when closing the raw
device after unpublising the partition, as the close_hook pointer which sits
in the device info now was 0xdeadbeef. This should make for example unplugging
USB devices work as expected.

inactive until at least one reader and one writer have opened it. As
long as it is inactive, reads from and writes to it just block. When
active, they behave as before (if there's no counterpart writes fail:
SIGPIPE + EPIPE, reads return 0). When both reader and writer count
drop to zero, the pipe becomes inactive again.
* Allocate the ring buffer lazily when the pipe becomes active and
delete it when it becomes inactive.
This makes the pipe implementation FIFO compatible. IOW, FIFOs work as
expected as far as I've tested them.

- Moved most file_system_module_info hooks into separate structures.
Those that operate on mounted volumes to fs_volume_ops, those
operating on a vnode to fs_vnode_ops.
- Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
again.
- Instead of a void* volume and node cookie hooks are passed a
fs_volume and fs_vnode structure pointer, which contain the cookie
and an ops pointer (fs_volume a few more things).
- The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
instead of the volume ID. So does vfs_get_fs_node_from_path().
- Added type and flags arguments to publish_vnode() and the
get_vnode() hook and removed the type argument from lookup() hook.
Added vnode::type using formerly unused bits to store the node type.
Simplified a few things in the VFS due to the now always available
node type.
- Added fs_volume_ops::{create,delete}_sub_vnode() and
fs_vnode_ops::get_super_vnode() hooks. They are used to support file
system layers, e.g. allowing to extend an FS not supporting BeOS
attribute with attribute support. Needs some more work in the VFS.
- Added fs_vnode_ops::create_special_node() hook for creating special
nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
changes. Removed all other FSs from the image for the time being.
We'll see whether further API changes are necessary before porting
them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
- Added syscall _kern_create_fifo() (used by mkfifo()), which creates
a special node (type S_IFIFO) in the respective file system.
- When a special node is published the VFS creates a respective sub
node. Currently only FIFOs are supported.
- Added a little support for FIFO subnodes by using functionality from
the pipefs.
- Added mkfifo to the image. It can create FIFOs in the rootfs, but
the FIFOs aren't really usable ATM, since they still work like
pipes, i.e. readers and writers need to have them open at the same
time.
* Some smaller changes in the VFS:
- Made the *_CALL macros nicer to use (vargs).
- Refactored FS entry lookup into new function lookup_dir_entry().
- create_vnode() no longer just calls the FS create() hook. First it
looks up the entry and uses open_vnode(), if it already exists. This
is necessary for two reasons: 1) The FS might not support create()
while still allowing to open() entries. 2) When the FS has other
layers on to of it (or the respective node) it might not be
responsible for opening the node.

notifications at all as the node is removed from the directory at this point
already
* Forgot to delete the device watcher instance after removing all monitors
* The PartitionRegistrar in DeleteDevice() was set to already locked which is
not the case
* Someone probably forgot to add a PartitionRegistrar to the media checker - it

obviously messed up the reference counting a bit

The dividing line is back although with a little more spacing. Also the icon
spacing is a little increased and I added a subtle outline as well as a little
brighter background for the active icon look. The placement logic is now not
independant of each other anymore, otherwise I couldn't center both images
as a unit. But only the vertical placement is affected.

introducing a small wait before doing the mode set, it works every time. Will see if I can
reduce the spin timer though with some more tests.

space left for the new log entry, it did call cache_sync_transaction(), and
then just assumed the space would be ready. But since the transaction could
have been written before that call by the block writer, and since the
_TransactionWritten() hook is now called asynchronously,
cache_sync_transaction() actually has to flush all pending TRANSACTION_WRITTEN
notifications before returning to the caller.
* To implement this, block_cache now publishs a condition variable, and
wait_for_notifications() adds a fake notification that signals that one.
Since the notifications are handled in FIFO order, this guarantees that
the previous TRANSACTION_WRITTEN hook is done.
* notify_transaction_listeners() could accidently delete notifications that
still had pending signals. Now, it will defer the deletion to the notification
thread instead in that case. This should fix bug #2008.

* Added a small DeviceWatcher class that reacts to entry creation/removal
* Implemented a way to start/stop node monitoring
* Start watching for devices after the boot volume has been mounted and the
the second initial scan was run
The disk device manager now creates and scans a device when a "raw" node is
published and deletes the device on removal. This makes hot-plugging of disk
devices (for example memory sticks using usb_disk) work. Their partitions will
be scanned and published so they can be mounted. Somehow the removal of the
partitions does not yet work however, any insights are welcome.

* The boot loader and kernel now use the placement info that
generate_boot_screen now generates.
* Made the code that draws the images handle the case where any of the images

called without having the cache's lock held.
* The only downside to this approach is that ending a transaction now needs
additional memory, and might therefore fail - that could be fixed by
allocating that memory upfront with the start of the new transaction,
though.
* Therefore, I reverted the cache lock to a benaphore, as the recursive
lock is no longer needed.
* The block writer thread is now a block writer and notifier thread: it will
wait for up to 2 seconds on the sEventSemaphore, and if nothing comes in,
it will continue with its previously sole job.

check in notify_transaction_listeners() didn't hold, although the
cache_hooks were deleted anyway. I've introduced a listener_change

any change makes the iteration unsafe. Should fix bug #2008 for real.
Nevertheless I thing the transaction listener concept needs revision.

Instead return the directory vnode, so the calling function can insert it after
all vnode initialization is done. Otherwise entry created notifications are
sent upon inserting the node into the directory for vnodes that are not yet
fully initialized (i.e. they have no type or the device hooks are not yet set).
That would cause for example ioctls to fail when someone would react to a
notification of a newly created device.

* Added quasi-standard getpwent_r() and getgrent_r().

* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.

in the buffer, they need to be notified after a read when their
minimal write size requirement has just become satisfied. We were
notifying only when there was no space in the buffer before, which
caused bug #1755.
* Removed Inode::NotifyWriteDone(). It's not needed anymore, since we
don't queue writers. They are always all notified, so that one doesn't
have to notify the next one, when it's done.
* Renamed *Request* to *ReadRequest, since we do have WriteRequests now
as well.

* The bios_ia32 video platform code now stores the available VESA modes in
the new vesa_modes kernel_args field.
* When configuring a VESA mode via settings file, it's no longer needed to
specify the exact mode - the closest available mode is now used. This should
help with bug #1962.
* frame_buffer_console_init() now also creates a boot_item for the VESA modes
in the kernel_args.
* The VESA accelerant now filters the mode list to only contain modes that
are actually supported.
* Moved non-shared vesa driver data into its own file vesa_private.h.

- Added a "root" vnode to the io_context. It is used for resolving
paths and converting nodes to paths instead of sRoot. Some more
passing around of io_context structures was necessary.
- Introduced a new lock sIOContextRootLock to protect
io_context::root. The current uses of io_context::io_mutex
(put_vnode(), remove_vnode() while holding it) looked too suspicious
to use that mutex in vnode_path_to_vnode().
- Added _kern_change_root() syscall and chroot() libroot function.
- Added chroot coreutils program to the image. Funnily it seems to be
much easier to set up a little jail than under Linux (just copy
bash and libroot.so into respective subdirs; mount another pipefs
if you want pipe support).
With Haiku allowing direct access to directories via inode IDs
jailing is obviously not very secure at the moment.
- Added /var/empty to the image. It will be the chroot target for ssh.
* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
longer held when calling dir_vnode_to_path().

- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.

* Refined the way how the default resolution is chosen: it now prefers the
above with hi/true color over a width of 800 in hi/true color over the
same order including palette modes.
* If no suitable mode could be found, it now chooses the first mode from the
list, if any, so that a VESA mode is always used when possible.

that they are ordered by size.
* This actually doesn't seem to be the case for all cards. Hence, we now
search for an appropriate mode only after we've collected all modes.
* Extended find_video_mode() to be able to ignore the height of a video mode;
that way, we can prefer a horizontal resolution of 800 without having to
care about the aspect ratio.
* This fixes bug #1975.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

vnode from the hash before putting it caused all sorts of problems.
* For example, BFS would trim its preallocations when the vnode is put;
if someone would read that same vnode after it had been removed, but
before BFS could trim it, it would read the old vnode which still
seemed to own the blocks which would subsequently be freed.
* This fixes bug #1914, and should also fix bug #1956.

This finally gets memory consumption to a moderate level; even

file system to not fill newly created space with zeros.
BFile::SetSize() now uses this, while [f]truncate() does not. This
is only a temporary work-around until BFS supports sparse files.
* Apps that want to reserve space to fill up later should use
BFile::SetSize() for now, as this will be a lot faster than
[f]truncate().
* cache_io() and the functions below now use a special mode when you
pass in a NULL buffer: for read access, the cache is only populated
(useful for prefetching), for write access, the file is filled with
zeros.
* Implemented BFS's Inode::FillGapWithZeros() using this method now.

could reverse the usual locking order -- the VFS could potentially call
the remove_vnode() or put_vnode() FS hook, which in turn could use the
file cache, thus resulting in a deadlock. Now we release the store ref
before locking the cache.

This is not an exact science, since we've got the version string for
every single object file that has been linked in, but my heuristic seems
to be good enough.

apps), and automatically selecting the right set of libraries in a mixed
gcc 2/gcc 4 environment.

* The boot splash code now checks wether debug screen output is enabled or not
using the above function.
* The boot splash code no longer maps it's own copy of the frame buffer, instead,
it will use the boot item feature as the VESA driver does. Also removed the
lock, as that's not needed at all.
* Renamed splash.cpp to boot_splash.cpp, and boot/splash.h to boot_splash.h
(it's not part of the boot loader, but the kernel).
* Removed dead code from boot_splash.cpp, added license. Replaced license
header in boot_splash.h to a style guide conforming one.

* dir_open_entry_ref() now always resolves symlinks, all other uses of
entry_ref_to_vnode() keep their previous behaviour, though.

read_stat() hooks to return the correct symlink length in st_size.
* Our readlink() does now comply to the standard (and BeOS).
Additionally if the buffer is big enough it is nice to non-conforming
