(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.

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".

Renamed the user syscalls to the new style.

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.

in device_manager.h).
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

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.

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
could be changed at startup (adapted to system properties).
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

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).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6897 a95241bf-73f2-0310-859d-f6bbb57e9c96
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().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6868 a95241bf-73f2-0310-859d-f6bbb57e9c96
else is not found here. The BeOS kernel also exports these two *_etc()
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@6700 a95241bf-73f2-0310-859d-f6bbb57e9c96
Copied over the function description of user_strlcpy() from x86/arch_cpu.h
to this file.
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().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6691 a95241bf-73f2-0310-859d-f6bbb57e9c96
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@6687 a95241bf-73f2-0310-859d-f6bbb57e9c96

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.

of the one that issues the alarm - it now does an ugly cast to get the
real thread structure. It would be nice if we had an additional user
parameter to a timer event.
Thanks to Travis for reporting this one!

{get|put}_physical_page_tmap() directly.
Also replaced all occurrences of "addr" with "addr_t".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5938 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Wrapped everything but #includes in #if _KERNEL_MODE to keep from
redeclaring/definining operator new and nothrow in userland.

is now honoured: the shortcut is now only made if it's okay to do it. Added
a comment what we could do to further improve performance.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5788 a95241bf-73f2-0310-859d-f6bbb57e9c96
forgotten about different address spaces with direct (unbuffered) pipe transfer,
shame on me.

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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5305 a95241bf-73f2-0310-859d-f6bbb57e9c96

else (libroot).

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

- Made module names B_PATH_NAME_LENGTH long.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5181 a95241bf-73f2-0310-859d-f6bbb57e9c96

- For functions where name strings are both input and output parameters that
may be truncated if too long, updated copy-in procedure to allow truncation
without returning an error.

I am not sure if this call is supposed to set the hardware clock.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5143 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a comment about how to make computing the seconds passed since 1/1/1970
more efficient.
Some slight other changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5142 a95241bf-73f2-0310-859d-f6bbb57e9c96
Commented the debug welcome message in rtc_init().
Moved the seconds per year calculation into a separate function.

Renamed all static g* variables to s*.

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

on disk to match to be able to find it, changed the ToDo: comment in the
affected function, and added a test call to vfs_get_module_name(); our
bootfs cannot handle the path depth/length required to be a useful module
host, so we still have our recursive search algorithm in place for now.

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).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4516 a95241bf-73f2-0310-859d-f6bbb57e9c96
"sudden unmounts" (as far as that can work). This replaces the weak
find_mount() call used at several places in the fs index functions.
