Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9254 a95241bf-73f2-0310-859d-f6bbb57e9c96
Should be tested and verified more intensively, though.
Moved the creation, initialization, and deletion of the team_arg structure out of
team_create_team(); it's now also used by exec_team().
Renamed kfree_strings_array() to free_strings_array().
Renamed the fields of the team_arg structure to be more in sync with the names used
at other places.
Fixed the routine that copied the environment/arguments into the userland space.
Improved and fixed the user_copy_strings_array() function.

Fixed some return types.

Minor cleanup.

The write functions didn't change the buffer address on a partial write

Fixed a warning that popped up if TRACE_VM was defined.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9110 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now prints a warning if the device driver doesn't handle iovecs correctly.
Again, this could lead to very strange behaviour.

devfs_read_stat() now (presumably temporary) sets the size of the device

if the size unequals zero.

* Turned sMountOpMutex into a recursive lock.
* Re-inserted sMountOpLock locking in vnode_path_to_vnode(). It doesn't
deadlock on mounting anymore. :-P
* Added a check in fs_mount(), whether the mount point is a directory. If
it wasn't, in general it wouldn't be possible to get its parent
directory.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8993 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented rootfs_write_stat() completely. rootfs_read_stat() now fills

rootfs_write_stat() now properly locks the node access.
Minor cleanup.

Removed the STREAM_TYPE_ constants.

IDE drivers :-)) don't respect the total amount of bytes to be read in the
former readv() (now read_pages()) call. This can potentially fix all sorts
of strange errors in userland :)
Fixed the debug build.

recreates a race condition, having it here breaks the kernel as fs_mount()
calls this function and already holds the mutex.

* Clarified a comment in fs_mount().
* Added a bit of documentation regarding the mutexes and the basic vnode
functions.

Userland. It must always set the d_pdev and d_pino fields and, if the
Entry refers to a mount point even replace d_dev and d_ino.
* Added a TODO comment to entry_ref_to_vnode(). It should take care of
mount points, as vnode_path_to_vnode() does, I believe. Will verify
and fix that next.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8921 a95241bf-73f2-0310-859d-f6bbb57e9c96
this is the one thing most likely to fail - it now also handles this case
gracefully instead of dying.
Small cleanup, cleared some other ToDos: some user functions now delete
the area when they could not copy the target address.

leaving the tags Qt style though. That's a bit weird, but that's the
way Axel likes it, and we want to keep him happy, don't we? ;-P
* The common_[path_]read_stat() now fills in st_dev and st_ino in the
result stat structure after the FS had its go. The information is
readily available in the VFS, so why bother the FSs. In fact devfs
didn't (and still doesn't) fill in st_dev which gave dev_for_path()
some head ache.
* Modified _user_open_parent_dir() to accept a NULL buffer for the
entry name and added a doxygen comment for it.
df now works properly on Haiku (save that printf() doesn't support
floating point numbers at the moment).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8898 a95241bf-73f2-0310-859d-f6bbb57e9c96
always also access it through the devfs_vnode. This also solves an issue
in devfs_read() where an access of a cookie->stream would crash the
kernel, since cookie->stream was not set in devfs_open().
* devfs_open() now doesn't fail for directories and symlinks anymore.
That prevented BNode to work for devfs dirs and symlinks.

`.'. This fixes the _kern_open_parent_dir() syscall for the root directory.
I realized, that rootfs_read_dir() doesn't return the entries `.' and `..',
unlike Be's rootfs. Shall I add those, Axel?
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8895 a95241bf-73f2-0310-859d-f6bbb57e9c96
This has the advantage that the device can now be access in the right context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8876 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed the calculation of the amount of bytes read in bootfs_read_pages().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8874 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added an vfs_get_cookie_from_fd() call to at least temporarily support the
cookie as in the original devfs (not sure yet how this changes).
Implemented vfs_get_file_map() which calls the corresponding FS function.
Moved vfs_get_vnode_cache() around.
vfs_get_vnode() temporarily does its job unlocked - its only to be used (safely)
from within the file cache, but this should definitely be done better.
Fixed a bug in get_vnode_name() - it did not support getting the name of
a root directory; it didn't pass the call through to the parent file system.
Fixed a bug in _user_entry_ref_to_path() which would add another "/" for
files immediately under the root (ie. "df" showed "//boot" as mount point
for the boot partition).

node and its interface directly. It will also convert the old interface into
the new one to simplify the implementation.
devfs_open() now contains the former pnp_devfs_open() as well.
devfs_publish_device() no longer passes the "ident" parameter to its lower
layers - it will be removed.
The VM fs interface has changed to better match the one of the device interface.

The VFS is now responsible for allocating the cache object - it will call
the VM to do that if necessary.
Added another accessor call to a pointer to the VFS private vnode object.

Added small description to _vm_map_file().
Minor other cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8816 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed syscalls to the new scheme.
Some minor cleanup.

The kernel no longer trashes memory when you delete a port without any
messages in its queue (i.e. you can now safely link against libbe.so :)).

which from now on relieves us from the duty to maintain syscalls.S and
syscalls.c manually. Either includes a generated file.

yet, though (instead, it directly performs all requests, so there is no
functional difference to the previous mechanism).
devfs and the file cache will directly access the I/O scheduler. There is
one scheduler per raw disk device; devfs detects that automatically, and
all I/O will go through the scheduler, then.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8683 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now accepts strings of any size, reduced the stack consumption.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8559 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added comments from storage/NodeMonitor.cpp to the syscalls here (they
will be removed from NodeMonitor.cpp), and adapted them where necessary.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8237 a95241bf-73f2-0310-859d-f6bbb57e9c96

load_kernel_add_on() now sets the text section read-only & execute after
having loaded the area - note, it currently doesn't have any effect anyway :)

there is no boot device available - this will prevent modules from getting
lost.
Added a comment to open_module_list() about its limitations while booting.

Fixed read/write calls to use and update the descriptor position.
Removed the CHECK_USER_ADDR() macro; it's now using the usual (more readable) check.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7967 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed KFileDiskDevice functionality for now (since it would have required more changes).
Also disabled actual partition publishing/unpublishing, because this will
be done differently.
This change will temporarily break the DiskDeviceManagerTest build.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7914 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed thread_atkernel_exit() to look less broken - the way and when it's
called should still be investigated: NewOS looks a lot cleaner here.
create_thread() now creates the kernel stack upfront, so that it can easily
bail out of that fails. The user stack creation now makes use of B_BASE_ADDRESS
and is therefore a lot better and simpler. In case user stack creation failed,
it should now be able to handle that a lot more gracefully - but that hasn't
been tested yet...
Some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7897 a95241bf-73f2-0310-859d-f6bbb57e9c96

fails, this is a cosmetic change anyway :-)).
Now correctly cleans up in case elf_load_user_image() fails.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7883 a95241bf-73f2-0310-859d-f6bbb57e9c96

load_kernel_add_on() now protects the text area read-only (theoretically,
