20c4c9e77e Don't trust the user, and enforce the iovec limit.
Also check for negative positions smaller -1
(as -1 means using current address).

f58cf973ad mmlr+bonefish(+axeld - I put the bug in there ;-)):
* Inode::MayReleaseWriter() would release the semaphore too often; therefore,
  Inode::WriteDataToBuffer() now loops in case it still couldn't write anything
  instead of failing - this fixes a race condition (ie. a device is full message).
* In case the read request got filled two times (while adding the request, and
  after waiting for it to become filled), ReadRequest::PutBuffer() overwrote the
  output data. This fixes bug #1331.

edb15b5565 bonefish+axeld:
* Simplified the notification framework: removed the updater stuff completely;
  it was only there to account for some peculiarities of the node monitor which
  we now solved differently.
* NotificationListener no longer includes a doubly linked list link for convenience;
  it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
  longer possible to just remove some flags separately, just to stop listening
  completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
  that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
  couldn't do a lot with the KMessage in the kernel without using a private API.
  Now you will have to use the (private) notification manager to use the node monitor
  from inside the kernel. At a later point, we might introduce a public API for that,
  too.

ba8c1ff561 Make partition access saver. attempts to read or write outside of a partition
now fail with B_BAD_VALUE. It's also no longer possible to overwrite the begin
of a partition by specifying a negative position, as negative positions are no
longer translated into 0.

f4da50b768 Computed the netmask in net endianess. The wrong netmask caused
misrouting when the net server set up the loop device, thus stopping the
net boot process.

fe679b9fa7 axeld+bonefish:
* Refactored RescanDiskSystems(). Pulled out a function
  _RescanDiskSystems() that scans for either file or partitioning
  systems. RescanDiskSystems(), which scanned for file systems only
  before, is used from the constructor as well (open_module_list()
  works in the early boot process since a while).
* Made InitialDeviceScan() and partition scanning safe to be called a second
  time. We call it directly after the kernel has mounted the boot
  volume, now, so that additional disk systems from the boot volume have a
  chance to recognize previously unrecognized partitions. This is a
  temporary change only; later the disk device manager shall
  automatically find out when new disk systems/devices/whatever are
  available.

9e8dc2a9bb [Sorry, couldn't split this one up any further.]
* Images preloaded by the boot loader had to be modules to be of any use
  to the kernel. Extended the mechanism so that any images not accepted
  by the module code would later be tried to be added as drivers by the
  devfs. This is a little hacky ATM, since the devfs manages the drivers
  using a hash map keyed by the drivers inode ID, which those drivers
  obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
  doesn't implement the former (all old-style drivers), thus making it
  possible to BFS, which uses the file cache which in turn requires
  read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
  more flexibly be extended and deals more gracefully with
  arbitrarily-size data. The disk_identifier structure still exists,
  though. It is added as message field in cases where needed (non net
  boot). Moved the boot_drive_number field of the bios_ia32 platform
  specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
  initialization code into the stage 2 loader, which can now be loaded
  directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
  does no longer use the RemoteDisk protocol (it could actually be
  removed from the boot loader). It also parses the DHCP options in the
  DHCPACK packet provided by PXE and extracts the root path to be
  mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
  added support for network boot. In this case the net stack is
  initialized and the network interface the boot loader used is brought
  up and configured. Since NBD and RemoteDisk are our only options for
  net boot (and those aren't really configurable dynamically) ATM, the
  the boot device is found automatically by the disk device manager.

Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

25f46ea449 * Reserving areas never put down their reference of their address space when
removed in several cases.
* vfs_get_vnode_cache() now always gives out a reference to the cache it
  returns; if it needs to allocate a new one, the vnode owns one reference,
  and the caller another.
* therefore, file_cache_create() now owns a reference to its vm_cache_ref, and
  frees it in file_cache_delete().

348be5b50b * Introduced the new static lock sVnodeCoveredByMutex to guard the
vnode::covered_by fields. Together with sMountOpLock it allows write
  access, either lock alone suffices for read access. Before
  sMountOpLock had to be acquired for read (and write) access, which
  meant that while mounting/unmounting a FS path resolution would have
  to wait. In case of the UserlandFS this would even cause a deadlock
  while mounting if the client tried to resolve the path of the device
  to be mounted (e.g. by opening it).
* Added a clarifying comment about read access to the
  fs_mount::covers_vnode/root_vnode field and removed locking in
  resolve_volume_root_to_mount_point() which was not necessary for
  explained reasons.

* dir_vnode_to_path() was broken for file systems that didn't support
  the get_vnode_name() hook. It resolved the mount point too early, so
  that it was searching the mount point and not the FS root dir for the
  node. It uses the get_vnode_name() function now (before resolving the
  mount point).

c40fe37f0b * Reverted the changes r17693 made to vfs_get_vnode_cache(); instead, vm_create_vnode_cache()
will now grab a reference to the vnode as well if successful. This way, vfs_get_vnode_cache()
  now actually works how it should: it will now always grab a reference to the cache and
  its underlying vnode. This removes an extra reference to the vnode (and vm_cache) that
  got ignored before and prevented volumes to be unmounted (or file caches to be removed).
  Thanks to Korli for pointing this out.
* file_cache_create() is now aware of that extra vnode reference and releases it; unmounting
  volumes is now working again as it should.

acac7c6834 _vm_map_file() did in fact not work correctly, but the main problem was
vfs_get_vnode_cache() which did not acquire an extra reference to the
cache_ref when the cache had to be created.

65bd831cbb * KDiskDeviceManager::_ScanPartition() can now run synchronously (and execute the
scan job in the calling thread).
* KDiskDeviceManager::InitialDeviceScan() now runs synchronously, so that
  get_boot_partitions() doesn't need to do this ugly wait hack.
* KDiskDeviceManager::CreateFileDevice() can now run synchronously as well, which
  fixes a deadlock in fs_mount() - note, mounting file devices still doesn't work,
  though as Haiku's BFS doesn't allow this right now.

  still for relative ones from the volume root) - it just tests if the
  mount IDs fit, so it only returns successful if the path really is on
  the desired mount.

* devfs_publish_partition() now accepts absolute device paths but relative
  partition paths.

675c19c9cf * fs_sync() and free_vnode() now use the file system's fsync() hook to write back
changes made to a file instead of directly using vm_cache_write_modified() -
  besides making the file system more independent from the file cache, this also
  works around a possible dead lock (that is to be fixed in a later commit).
* fs_sync() no longer uses vnodes from the mount's vnode list directly to write
  back the changes made to them, but gets them via ID instead - this makes sure
  the vnode is in a valid state and fixes a race condition with free_vnode().

abb84c7d51 Removing the nodes from the unused list in fs_unmount() had the side effect that
the root vnode was tried to be removed as well (which resulted in a crash).
Since playing with the root node reference count is a bad idea anyway and opens
a big race condition (with regards to the unused list), we no longer do that
now, until it's safe.

* create_sem_etc() now calls the above function in case there are no semaphores
  available anymore; this usually frees up to 2 semaphores per node (one from
  the cache if there is a file cache attached, and eventually one from the
  file system).

957a1b17eb * Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
  compiler/linker flags specifying the kind of position independence
  the kernel shall have. For x86 we had and still have -fno-pic, but the
  PPC kernel has -fPIE (position independent executable) now, as we
  need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
  code from the kernel ELF loader. Almost completely rewrote the PPC
  specific relocation code, though. It's more correct and more complete now
  (some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
  Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
  being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
  (made OF device iteration a bit more flexible on the way -- the search
  can be restricted to subtree). Furthermore we really enter the kernel...
  (Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
  called by acquire_spinlock()). kprintf() works, though.

* better balanced vnode ownership on vnode_store creation (vnode_store
  released the vnode before if its creation failed).

  it could have had a mount structure associated as well.

7121425eb5 Turns out we could remove a mount point...
Under BeOS remove_vnode() is failing in this case, which looks like a good idea to imitate.
Also, pipefs/rootfs didn't handle that case - they even removed the entry before calling
remove_vnode() - they now behave correctly. And also BFS now returns the actual error code
received from remove_vnode() instead of B_ERROR.

0fc0129604 Fixed another stupid bug in all readv()/writev() versions: the position of
the read/write access was only correct for the first entry in the iovec.
These functions should be updated to use read_pages()/write_pages() where
possible, anyway - right now, they only save some kernel calls, while they
could be processed by the device at once.

3ea780cdf9 If booted from an image, the list of possible boot partitions is now ordered by
some heuristic: when you booted from a CD, CDs are preferred; else, volumes with
names like "Haiku" or "System" are preferred - if someone has better ideas, please
shout.
Note, this heuristic will only come into play if the boot loader was loaded from
an image (ie. floppy/CD/network), and you didn't choose any boot device.
Added evil methods to the Stack class that come in handy (you can now directly
access the array) for this.

2db3fced5f Moved vfs_bootstrap_file_systems() and vfs_mount_boot_file_system() out of vfs.cpp
and into its own file vfs_boot.cpp.

Added basic support for booting from CD - it doesn't give CDs a higher priority,
so you could end up booting from HD when you didn't explicetly select "CD-ROM"
in the boot loader. Eventually, it should only boot from HD in this case, if
booting from CD failed (because of a missing boot partition or whatever).

fs_mount(), _kern_mount(), and _user_mount() will now return the dev_t of the
mounted device, and not just B_OK. Maybe we should have fs_unmount() work on
a dev_t instead of a path as well...

681779f1c8 Our close-on-exec flag handling was broken: it's supposed to be specified per slot, not
per file descriptor (a descriptor can be shared among several slots). There is now a
second table in the io_context structure that contains that information in a bitmap.
There are now two new (private) functions to control the close-on-exec flag, fd_close_on_exec(),
and fd_set_close_on_exec().
F_DUPFD, dup(), and dup2() are supposed to clear the close-on-exec flag on the duplicated
slot - this fixes bug #57 (no output after a redirect of a shell builtin).

5b14757a30 We now have a consistent scheme what the file system should do with its root
node: like in BeOS, it *must* own the root node (ie. via publish_vnode()),
unlike in BeOS, it must also drop that reference on unmount (symmetrical
behaviour definitely makes more sense to me than the Be way).
Since all existing file systems for Haiku behaved differently, I brought them
in line (only pipefs already adhered to that new standard for some reason,
rootfs did only released the node, devfs did nothing - despite it's probably
not really useful to be able to unmount them).
fs_mount() will now panic if a file system does not do this correctly (useful
for file system developing).
Unmounting is now theoretically working again: when trying to unmount a BFS
volume, the kernel crashes in the block cache destruction... (but that's work
for tomorrow).

eab435cd59 vfs_get_vnode_cache() now only allocates a new cache if requested: this
prevents the system to allocate caches for files that don't use or have
a file cache (ie. only those can be mmap()ed!).
Therefore, cache_prefetch() no longer crashes when trying to prefetch
files without a file cache.
read_into_cache() no longer does anything if the requested size is 0.
Fixed a bug in cache_prefetch_vnode(): if the cache couldn't be retrieved,
it put the vnode, but didn't own it (the caller does).

c50cfe23dd Fixed crashing bug in remove_vnode(): it freed the vnode, but it didn't
remove it from the hash, and thus, left a dead pointer around.
free_vnode() does now also remove the vnode from the hash - this is done
so that the file system is notified about removal/put of the vnode before
there is a chance that this vnode is recreated/reloaded (could make the
life of file system writers a bit easier).
