5f2d64a25e * _user_{send,recf}msg() no longer copy iovecs on the stack. They use
the heap and the IOV_MAX limit.
* They also take the responsibility of copying the ancillary data in and
  out.
* These syscalls were badly broken. They used a member of an
  uninitialized structure instead of the iovec pointer passed from
  userland. sendmsg() would thus fail or send arbitrary data, recvmsg()
  would overwrite arbitrary memory.

0cc82d47d4 Added close_fd_index() which is pretty much like close(), but gets the
IO context in which to close the FD.

bdfe92370f gcc4 build fix. Here is one of the two errors:

3118b3a7cb * Added fd_ops::set_flags() hook. It's only implemented by socket FDs
ATM.
* Changed common_fcntl() to also work for non-vnode-based FDs. Only the
  operations that require a vnode do fail now. F_SETFL uses the new
  fd_ops::set_flags() if available, falling back to the vnode respective
  operation.
* Changed some direct accesses to file_descriptor::u::vnode. It was safe
  in those cases, but might not be anymore if we ever change fd_vnode().

ftp can at least connect to servers again, now, but apparently we still
have a problem with syscall restarts -- downloads fail after one second,
when the timer goes off.

ac0e5c1ce5 The fs_sync() function (or any other, for that matter) must not hold the
sMountMutex lock when calling sync() on a file system. This fixes a potential
deadlock (I just encountered for the first time).

75015ff525 * 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.

df50f7a9b4 * Changed the way the socket functions work:
- 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.

same as !IS_USER_ADDRESS.

  syscall flag.

36de598e0f * block_cache_sync[_etc]() now also waits for all notifications to be handled.
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
  need to).
* Unified the naming of the notifier/writer thread: renamed the thread to "block
  notifier/writer", and the variable holding the thread ID to
  sNotifierWriterThread.
* Added a few more doxygen descriptions to the private functions.

391fdf1e99 * notify_transaction_listeners() would always remove all listeners when it
was asked to. Unfortunately, it also removed the TRANSACTION_WRITTEN
  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.
* Rearranged functions a bit, moved notification/listener related private
  functions together.
* Added tracing entry for written transactions as well.

3568352d8d When a partition was unpublished from devfs the devfs_delete_vnode() would
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.

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

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

0d69c8378f On my system's BIOS / monitor there seems to be a race condition between grabbing the EDID info
and setting the video mode. The result of this is a garbage display every other boot. By 
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.

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.

the icons are centered.
* The boot loader and kernel now use the placement info that
  generate_boot_screen now generates.

  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.

(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.

  features have become available.

    was still changed.
  - unreserving memory did not update vm_store::committed_size.

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.
  - 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().

    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.

* If no suitable mode could be found, it now chooses the first mode from the

652c852666 * The previous code to retrieve the standard video mode did rely on the fact
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.

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.

cedc3f1eb8 * Rearranged EDID mode find process: in a first pass, we only accept hi- or
true color resolutions, the second pass that also takes those into account
  will only be run if no mode could be found before.
* I hope this will improve Urias boot screen experience.

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.

14438ad555 * write_cached_block() now moves a block to the unused list when it's
not referenced and clean (is no longer part of a transaction).
  This finally gets memory consumption to a moderate level; even 
  unpacking a large archive will no longer eat all memory.
* The "block_cache" KDL command will now print the number of unused
  blocks as well.

a call chain contains a specific symbol (or address).

  threads that have a specific function in their call chain.
* Removed extraneous white space.
