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).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8873 a95241bf-73f2-0310-859d-f6bbb57e9c96
_KERNEL_MODE is already defined when using kernel build rules, no need
to do it here manually.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8872 a95241bf-73f2-0310-859d-f6bbb57e9c96
couldn't be satisfied completely (ie. because the file size is not a
multiple of the page size).
It's no longer necessary to implement this functionality in the file systems.

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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8849 a95241bf-73f2-0310-859d-f6bbb57e9c96

Not yet used - might be used instead of the vm_cache page caching for the file cache.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8819 a95241bf-73f2-0310-859d-f6bbb57e9c96
It still contains a very dump version of a BeOS compatible block cache.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8818 a95241bf-73f2-0310-859d-f6bbb57e9c96
allocate a cache twice.
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8817 a95241bf-73f2-0310-859d-f6bbb57e9c96
allocate a cache twice. Now handles resource shortages gracefully.
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8770 a95241bf-73f2-0310-859d-f6bbb57e9c96
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 :)).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8736 a95241bf-73f2-0310-859d-f6bbb57e9c96
not support the read_fs_info() function - only the values that the VFS
does know about are filled in, then.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8735 a95241bf-73f2-0310-859d-f6bbb57e9c96
* null-terminated the result of common_read_link().
* Fixed return value of _user_read_link().

syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).

syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8703 a95241bf-73f2-0310-859d-f6bbb57e9c96
which from now on relieves us from the duty to maintain syscalls.S and
syscalls.c manually. Either includes a generated file.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8699 a95241bf-73f2-0310-859d-f6bbb57e9c96
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
that you can now also look up symbols in there.
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 :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8173 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8170 a95241bf-73f2-0310-859d-f6bbb57e9c96
it's not known (it currently only support the current version, of course :-).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7989 a95241bf-73f2-0310-859d-f6bbb57e9c96
Improved returned types.
Added and initializes Disk Device Manager.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7972 a95241bf-73f2-0310-859d-f6bbb57e9c96
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
Introduced RESERVED_REGION_ID definition.
Some minor cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7886 a95241bf-73f2-0310-859d-f6bbb57e9c96
stack - it just fails now (since create_area() currently panics when it
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
Replaced "addr" with "addr_t".
Header cleanups.
There is no need to call set_tls_context() in arch_thread_init_tls().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7880 a95241bf-73f2-0310-859d-f6bbb57e9c96
load_kernel_add_on() now protects the text area read-only (theoretically,
as set_area_protection() has not yet been implemented).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7879 a95241bf-73f2-0310-859d-f6bbb57e9c96
and (very) temporary extension, anyway).
- Fixed _user_create_area() - it will now also recognize B_ANY_KERNEL_BLOCK_AREA,
and it will not access a kernel address for B_EXACT_ADDRESS.
- create_area() will now handle B_EXACT_ADDRESS correctly as well.
- get_memory_map() will now silently ignore the missing final entry if the map
contains only one entry.
- The check for user memory was wrong in get_memory_map(); it worked, but it
was not necessarily portable.
- vm_reserve_address_range() was not correctly initializing the region.
- find_and_insert_region_slot() will now search for reserved regions when
B_EXACT_ADDRESS is used - not yet tested, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7871 a95241bf-73f2-0310-859d-f6bbb57e9c96
created a call around find_and_insert_region_slot() that takes care of
everything. Fixed B_BASE_ADDRESS support (it now really works).
First shot at a new VM function vm_reserve_address_range() that will be
used to fix our ELF loader issues (which needs to create adjacent regions
which the VM cannot guaranty at this point).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7870 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread exit - get_death_stack() now returns the interrupt state so that
it can be restored correctly later.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7865 a95241bf-73f2-0310-859d-f6bbb57e9c96
The stack of the main thread is now called "{team name}_main_stack" instead
of primary stack.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7863 a95241bf-73f2-0310-859d-f6bbb57e9c96

only).
Userland segments are now called _seg0rw/_seg0ro.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7851 a95241bf-73f2-0310-859d-f6bbb57e9c96
device with BFS - if it succeeds, it will print out the contents of the
volume's root directory.
fs_mount() now makes the mount structure available when mount() from the
FS is called - so that new_vnode() and get_vnode() can work.
fs_mount() did not correctly clean up when something went wrong; it also
didn't notice if the mount's recursive lock couldn't be created.
Some minor debug output improvements.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7845 a95241bf-73f2-0310-859d-f6bbb57e9c96
it's (almost) read only.
Added it to the build - libvm.a is now build as merged object file, since
the cache functions didn't get exported else.

something went wrong) - this would have hidden circular dependencies
as well.
Recursive directory scan was broken, it didn't filter "." and ".." out.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7829 a95241bf-73f2-0310-859d-f6bbb57e9c96
lock_memory() and unlock_memory() will now silently fail and return success -
that's only to get things working.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7754 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also made elf_lookup_symbol_address() less restrictive with respect to the
ELF symbol found (it now accepts all types, not only functions).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7714 a95241bf-73f2-0310-859d-f6bbb57e9c96
tested, though.
No longer copies the elf_header in insert_preloaded_image(); it's not used
at runtime (should be superfluous to keep in other kernel images, too).
dump_symbols() now ignores entries with invalid values - don't know exactly
what makes a good entry, but that should look okay.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7713 a95241bf-73f2-0310-859d-f6bbb57e9c96
standard byte order functions in the kernel).
Small cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7705 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed warnings when compiled with TRACE_ELF.
Changed elf_lookup_symbol_address() to returning more useful information.
It now also scans the extended debug symbol table if present - for now, this
only works with preloaded images except the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7701 a95241bf-73f2-0310-859d-f6bbb57e9c96
(in BeOS, all kernel areas are r/w).
If you use B_READ_AREA/B_WRITE_AREA flags, you make the area readable
or even writeable from userland!
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now uses the extended possibilities of the elf_lookup_symbol_address() call.
Fixed a bug in dbg_stack_trace(); it could crash at the top most stack frame.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7698 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7570 a95241bf-73f2-0310-859d-f6bbb57e9c96
like any other module (yeeha!).
You can even unload preloaded images later on (to replace them with a
more up-to-date on disk version).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7532 a95241bf-73f2-0310-859d-f6bbb57e9c96
If an image cannot be created out of a preloaded_image, its resources
are freed now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7531 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Fixed missign file system unload.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7527 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now registers its images as it should do (so you can use commands like
listimage in userland).
Added new debugger command "image".

freed in the wrong order in case of an error (could have crashed the kernel).
Implemented insert_preloaded_images() which prepares the preloaded images
for later use in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7520 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed those syscalls to the new naming scheme.
Updated the syscalls to support stat extensions.

Fixed some comments.
Removed realpath() from probe.c for now - mechanism will be changed, and that
prevented it from being built as part of the kernel; it's currently not functional.

be any size, not just full path names (even without the file name...). Optimized
it to only traverse paths that match the prefix.
The built-in modules now honor the prefix as well.
Renamed module_iterator::path_stack to stack.
The system add-on path was even wrong (but that didn't matter yet, as we're
still do a recursive search for modules).
The user add-on path now matches the real one - but that should probably be
retrieved from calling find_directory(), anyway...
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7483 a95241bf-73f2-0310-859d-f6bbb57e9c96
The prefix will obviously ignored currently!
Fixed get_next_loaded_module_name(); it will now work correctly (doesn't check, though,
if the module is currently loaded...).
Removed the module_test() function - doesn't belong here.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7465 a95241bf-73f2-0310-859d-f6bbb57e9c96
main, not by getting the module any longer.
It now also creates the root node directly.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7438 a95241bf-73f2-0310-859d-f6bbb57e9c96
team_create_team() now uses the B_NORMAL_PRIORITY constant instead of the number directly.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7425 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed vfs_register_filesystem() to vfs_register_file_system().
Changed return codes to status_t where appropriate.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7424 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added all of them - module_loader.c and boot_hack.c won't be needed anymore.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7351 a95241bf-73f2-0310-859d-f6bbb57e9c96
Nothing is tested right now, and it's not yet complete, but it's changed so that
it does compile in our tree (and looks a bit more like the other files, too).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7345 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed all old NewOS error codes.
Cleaned up the includes a bit.
Now prints out a list of preloaded images.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7331 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented the possibility for built-in modules - they have to be listed
in sBuiltInModules in module.c to be registered automatically.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7318 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added system_info.c to the build.
Added stats support functions to sems & ports.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7290 a95241bf-73f2-0310-859d-f6bbb57e9c96
The syscall is not yet connected, and the code has not yet been tested.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7179 a95241bf-73f2-0310-859d-f6bbb57e9c96
Incorporated NewOS change 1930: sends the parent SIGCHLD if the team
goes away.
create_thread() now returns B_BAD_TEAM_ID when the team is in death state
instead of ERR_TASK_PROC_DELETED.
Cleaned headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6997 a95241bf-73f2-0310-859d-f6bbb57e9c96
from thread_exit().
Removed team_remove_team_from_hash() as it's no longer necessary.
Also incorporated NewOS change 1930: maintain the parent/children lists.
Cleaned up the headers.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6996 a95241bf-73f2-0310-859d-f6bbb57e9c96
as already suggested in my earlier comment.
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6993 a95241bf-73f2-0310-859d-f6bbb57e9c96
Took the chance and cleaned it up even more; this change is not a functional change.

Taken from NewOS, thanks to Travis for pointing this out.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6971 a95241bf-73f2-0310-859d-f6bbb57e9c96
Saved the port_entry.closed member and now set the capacity to 0, since
it is not used any longer (reduces the size of the port table).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6956 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6955 a95241bf-73f2-0310-859d-f6bbb57e9c96
Right now, it allocates/frees the msgs from the kernel heap for every
message sent - that might be too slow for real world usage.
Also removed all known race conditions from the code.
Not tested at all yet, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6953 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6904 a95241bf-73f2-0310-859d-f6bbb57e9c96
the info from the wrong end of the queue.
find_port() did not return the correct error codes.
write_port_etc() checked incorrectly for a deleted semaphore.
B_WOULD_BLOCK would let various functions print out a warning for no reason
(the comments in the code actually didn't fit to the implementation).
"total_count" was counting the number of messages written, not those that
have been read (as the BeBook says).
Thanks to Bill Hayden who reported a lot of these.
Added TRACE macro and moved some of the dprintf()s to that.
Added/fixed some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6901 a95241bf-73f2-0310-859d-f6bbb57e9c96
run. Also create_port() now changes the port ID only when the port lock is
grabbed, so that we don't need to acquire the port list lock in find_port().
Removed setting lock to "0" in create_port() because if it's not 0 in the
first place, there is something seriously wrong (should add an assert there).

I don't know which part of me has written the previous version, but
it seems not have been supervised by a brain while doing it.
The read requests are now maintained per inode (as it has to be),
and there is one read lock per request.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6891 a95241bf-73f2-0310-859d-f6bbb57e9c96
Moved wait_for_team() into the exported kernel API region.
Added missing call for _user_get_current_team().
Made the team_kill_team() call to the BeOS compatible kill_team().

functions, and we might want to do that, too.
{receive|send}_data() are now interruptible from userland, but not when
called from the kernel.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6697 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented the B_CURRENT_TEAM mechanism for _get_next_sem_info().

out the port_info setup to fill_port_info(), implemented the B_CURRENT_TEAM
behaviour as described in the BeBook (well, almost, since B_CURRENT_TEAM
is not defined in R5, it's just "0"), improved error checking.
Cleaned up user syscalls.
Replaced SYS_MAX_OS_NAME_LEN with B_OS_NAME_LENGTH.
Banned strncpy().
Added our license.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6685 a95241bf-73f2-0310-859d-f6bbb57e9c96
Cleaned up _get_thread_info() & _get_next_thread_info() - factored out
the thread_info setup into fill_thread_info().
Is now using team_is_alive() instead of team_get_team_struct().
Replaced SYS_MAX_OS_NAME_LEN with B_OS_NAME_LENGTH.
Banned strncpy() in favor for strlcpy().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6683 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced some old error codes.
Explained a bit more how to solve a race condition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6681 a95241bf-73f2-0310-859d-f6bbb57e9c96
Removed old error codes.
Replaced the DEVFS_IOCTL_* with their Be equivalents. Note, the related
functions are not user space safe yet. But since the devfs will be
almost rewritten, there is no point in changing it now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6679 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added our license to the updated source files.
Minor cleanup.

a comment what we could do to further improve performance.

always zeroed anyway.
cmd_help() is now able to print out help about the specified command
only - it will also print out all aliases of that command. Reduced
the distance between the command name and its description; NULL
descriptions are now also allowed.
There is now a find_command() function that's used throughout the
module. Like in the Be debugger, it will now also accept partial
matches, i.e. "co" will most probably match "continue" (as long as
there is no new "co*" command added by another component). It will
first try to find an exact match, and only if that failed it will
search for a partial match.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5307 a95241bf-73f2-0310-859d-f6bbb57e9c96
Disabled dbg_get_serial_debug(); it's only used temporarily in the keyboard
device (and I removed its usage there, too).
Added "continue", "exit", and "es" commands as in the Be kernel debugger
(they will all exit the debugger and try to continue normal kernel execution).
Reordered the sources so that public kernel API is together.
Added a _user_debug_output() syscall (not yet activated) which dumps to the
kernel's serial output.

Removed the STREAM_TYPE_* definitions, it's now using the stat definitions
instead.
Cleaned the source a bit.

Added a comment about how to make computing the seconds passed since 1/1/1970

Some slight other changes.

respective setter/getter methods to the KPartition class.
If a partition is mounted, the field will contain the cookie the
FS's mount() hook passed back to the VFS. This way the FS has
access to its internal data structures. We need the cooperation

Added a comment about how to traverse the module path to find a given module -
could well be that we got that wrong (too loose, it will work perfectly, though,
just slower than it could be).

"sudden unmounts" (as far as that can work). This replaces the weak
find_mount() call used at several places in the fs index functions.
Fixed a bunch of warnings, mostly unused prototypes and variables.

The lock_memory()/unlock_memory() functions cannot be implemented right

kernel_os_arch_x86.o file that is genereated by libroot.
Removed duplicate implementations from this file.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4337 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made the "name" argument const for create_area_etc() and vm_map_physical_memory().
Moved some common conversion code (BeOS to NewOS VM constants) to separate
functions to clean them up a bit.
create_area() now automatically sets LOCK_KERNEL if the area is to be created
in kernel space (as I would guess BeOS does, too).

Temporarily #if'd out scan_pci() and removed the compiler calming hack for it.

delete_area() now only allows to delete areas you have created
yourself before from userland, again.
The kernel's delete_area() still allows everything, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4320 a95241bf-73f2-0310-859d-f6bbb57e9c96
delete. Added a comment how the security should be improved by adding another
restriction.
Also mentioned that it's probably a bad idea that vm_delete_region() will
not wait until the region has been freed, but just "mark" it as to be freed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4319 a95241bf-73f2-0310-859d-f6bbb57e9c96
that will call the internal vm_*() calls. This will make it easier to just
drop in another VM.
Also (partially - Ingo was faster) introduced the new syscall naming scheme
_kern_ & _user_ prefixes to them into the system namespace, and no longer
clobber the application namespace.
Removed the now unused user_vm_create_anonymous_region() call.

to work at all: recurse_directory() always returned failure, no matter what opendir()
returned (one semicolon too much), create_module() allocated only 4 bytes for
the module - sizeof(module) referred to the variable, not the structure name...
(the unfortunate consequences of the naming scheme I otherwise like very much -
it "just" took me 3 hours to hunt both bugs down).
Added some TRACE() and ASSERT()s.
Added a new debugger command "modules".

The CBUF_FLAG_CHAIN_TAIL is now set for the lastBuffer instead of buffer.
Removed some superfluous lines in cbuf_get_ptr(), and cbuf_ones_cksum16().
Fixed the buffer->length calculation in cbuf_truncate_tail() and added some
comments about the correctness of the code - should be investigated and fixed.

to the module interfaces. So the disk system will be informed, when a
shadow partition has changed and it is allowed to do necessary
adjustions (e.g. adjusting the cookie, the parameters, or on
partitioning system initialization even creating special child
partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
partitioning system can report at which index the new child shall be
inserted.

PrettyName() of the responsible disk system.
* Added change counter support and changes tracking.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4042 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed the disk_system_id parameter where superfluous.
* Got rid of the `child' variants of the _kern_{supports,validate}_*()
syscalls for moving and resizing. Reimplemented the real ones to do the
the right thing, i.e. they check all concerned disk systems now.
* Added _kern_supports_setting[_content]_parameters().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4020 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed handling of the deletion (removal) of shadow partitions. Formerly
the shadow partition corresponding to the disk device wasn't removed
properly.
* Added a shadow_id field to the user_partition_data structure which
contains the ID of the shadow partition, if it is one. The id field
will hold the ID of the physical partition.
