d4016ffdbb * A pipe can now be inactive and active. After creation it remains
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.

7ffafac8d7 * Reorganized the FS interface a little:
- 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.

5d7ee5e84a * Replace the path based lstat in the device watcher with the new device/node
based one. The path based version could not have worked for entry removed
  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
  did register the device on each run but never actually unregistered it, which
  obviously messed up the reference counting a bit

efb965d559 Introduce vfs_stat_entry_ref() that allows to stat a vnode based on a dev_t
and ino_t instead of a path. Supposed to work with node monitoring messages.
Took the name from vfs_entry_ref_to_path() that takes the same arguments, but
suggestions for a better name are welcome.

d0fc7c65c6 Patch by Philippe Saint-Pierre:
* Implemented RLE compression for the boot splash images, resulting in
  smaller kernel and boot loader.
* Only the boot loader contains the RLE compressed images, the decompressed
  buffer for the icons is passed to  the kernel via kernel args.

directly. This should fix #2008 again.

75ab36bd50 Refined again the boot splash artwork. Everything is now centered as a whole.
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.
Comments as always on the commit mailing list... :-)

807d3aa8e3 * If BFS's Journal::_WriteTransactionToLog() noticed there wasn't enough free
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.

06da81f012 Implement node monitoring in the kernel disk device manager.
* Added {Create|Delete}Device() analogous to {Create|Delete}FileDevice
* 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.

64379118a9 * Revised boot splash artwork, the logo is back in the lower right corner,
the icons are centered.
* 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
  is larger than the frame buffer.
* All drawing functions need to know the image width (analogous for bytes per
  row).

816957bd74 * Decoupled notifications from the block cache functions; they are now
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.

a5140cad6a cache_end_transaction() doesn't remove the transaction, so that the
check in notify_transaction_listeners() didn't hold, although the
cache_hooks were deleted anyway. I've introduced a listener_change
counter to detect changes to the listener list while iterating, since
any change makes the iteration unsafe. Should fix bug #2008 for real.
Nevertheless I thing the transaction listener concept needs revision.

3130aa793d Change the NodeMonitorService lock from a mutex to a recursive_lock. This
allows event listeners to add new listeners inside a node monitoring event
(i.e. if one wants to add a listener for the entry that has just been created
and triggered the current notification).

2509807a53 Change publish_node() of the devfs to not insert the node into the directory.
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.

  - has_precommitted was incorrectly set to true in the constructor
  - when a precommitted page was committed, vm_store::committed_size
    was still changed.
  - unreserving memory did not update vm_store::committed_size.
  - when precommitted pages were committed, their page count instead of their
    size was reserved.
* All this lead to bug #1970 which should be fixed now.
* Cleanup of vm_cache.cpp, no functional change.

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.

360be1fc45 * Implemented support for chroot:
- 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.

* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
  longer held when calling dir_vnode_to_path().

290946ce80 * Implemented some basics for supplementary groups support:
- 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.

071f9c3aa2 Build configurations shouldn't be done in svn controlled files, so I
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.

9e79133f4d * Reverted r22315 as far as free_vnode() is concerned: removing the
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.

a121b8c83c * Added a new flag for write stat: B_STAT_SIZE_INSECURE that allows a
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.

0956fd0502 Applied change proposed in #1917 after encountering the bug the third
time. Releasing the cache's store reference while holding the cache lock
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.

1b32947d3f * Aligned the semantics of the read_symlink() FS module hook with the
readlink() function. It is no longer required to null-terminate the
  string, shall not fail, if the buffer is too small, and shall return
  the length of the string actually written into the buffer.
* Adjusted rootfs, devfs, and bfs accordingly. Also adjusted their
  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
  apps and null-terminates it.
* BSymLink::ReadLink() explicitly null-terminates the string now.

f4af1fba51 Use the empty_index field as the allocation_id for large allocations and just
use the index of the first page of the allocation as an id. This removes the
need for separate id generation. This also fixes the possible problem of
multiple large allocations getting the same allocation_id (due to the limited
range of possible ids), which in the worst case (i.e. for adjacent allocations)
could cause pages to be freed that were still in use.

fae99f156e cached_block::Compare() was ignoring the upper 32 bit of the block
number. Was a problem only for partitions > 2^32 * block size (4TB
for 1KB blocks).

2b0b4bee36 store_acquire_unreferenced_ref() saves the pointer of the vnode it got
from the call to vfs_get_vnode() now. Only this way it is safe to call
store_release_ref() later (as the page writer does). We had a potential
race condition -- if called after vm_cache_remove_consumer() had
released the last reference, the old vnode might already have been
deleted.
