Most importantly, it now always uses map_physical_memory(), and no longer
relies on eventually mapped data by the boot loader (that the VM didn't
know about).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9418 a95241bf-73f2-0310-859d-f6bbb57e9c96
Exports the new insert_address_range() function as declared in boot/addr_range.h.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9416 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a kMaxKernelSize constant to be able to change that limit a bit
easier.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9415 a95241bf-73f2-0310-859d-f6bbb57e9c96
USE_WALL feature can now be used.
Started implementing a USE_CHECKING_WALLS feature, that has a kernel
daemon running that periodically checks the walls of *all* memory
allocations - does not work yet (because of some initialization order
problems).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9396 a95241bf-73f2-0310-859d-f6bbb57e9c96
team and process group IDs as well.
Added a ToDo item that process groups do only work well as long as
their group leader is still active.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9394 a95241bf-73f2-0310-859d-f6bbb57e9c96
ignored completely (so that zero and below become valid).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9393 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now uses waitpid() instead of wait_for_thread() - and surprise, it doesn't
work yet :)
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9372 a95241bf-73f2-0310-859d-f6bbb57e9c96
no longer pop %fs from the iframe in that case, too.
When we restore a custom stack, however, we'll now pop %fs from the iframe
as such strange threads may even do their own business with it.
Added some comments.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9369 a95241bf-73f2-0310-859d-f6bbb57e9c96
We also should disable interrupts in arch_restore_fork_frame().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9368 a95241bf-73f2-0310-859d-f6bbb57e9c96
always copies the arguments and environment arrays.
No need for the "owns_arrays" in team_arg anymore - it now always owns
them.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9363 a95241bf-73f2-0310-859d-f6bbb57e9c96
Switched to load_image() instad of using the old team_create_team() to start "init".
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9361 a95241bf-73f2-0310-859d-f6bbb57e9c96
The path name is now always taken from the provided argument list (except for
_user_exec() which now replaces args[0] with the path argument).
The team_arg structure know nows if it must delete its arguments or not - this
also fixes a memory leak in case team_create_team() failed when invoked from
userland.
load_image() is now also exported for the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9360 a95241bf-73f2-0310-859d-f6bbb57e9c96
Enhanced exec_test.c to use some process functions as well.
Switched to load_image() instead of using the old _kern_create_team() syscall.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9359 a95241bf-73f2-0310-859d-f6bbb57e9c96
process ID (in the current session).
get_death_entry() could call free() with interrupts disabled; now follows
the same mechanism as chosen with the groups (ie. it returns a pointer
to a death_entry to be freed by the calling function).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9354 a95241bf-73f2-0310-859d-f6bbb57e9c96
the specified process group (by passing in a negative pid, as in BeOS).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9351 a95241bf-73f2-0310-859d-f6bbb57e9c96
- we now have a working process group/session model. Implemented related syscalls
and the kernel backend, some POSIX process functions are now available in the
kernel as well.
- dying teams now monitor their exitus by leaving death_entry structures in
their parent team.
- Implemented wait_for_child() for pid == -1 and pid > 0; IOW waiting for process
groups is missing yet. Hasn't yet been tested intensively.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9350 a95241bf-73f2-0310-859d-f6bbb57e9c96
may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
(the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
Removed release_threads variable in release_sem_etc(), as it was useless.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9330 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also removed syscall for that function (shouldn't have been there in the
first place, anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9325 a95241bf-73f2-0310-859d-f6bbb57e9c96
no longer abuse the semaphore mechanism to carry an extra status value,
instead, wait_for_thread() registers a death_entry with the thread that
will be filled upon exit.
Removed delete_sem_etc() as it's no longer of use or available.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9323 a95241bf-73f2-0310-859d-f6bbb57e9c96
flag set.
Fixes _user_wait_for_thread() which returned an invalid return code in case
of error.
Some minor cosmetics.

not be restored from the iframe; it will be set by the scheduling code.
This is only of concern on SMP machines and could prevent TLS from working.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9310 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made it less vulnerable to thread-safety issues; it could occassionally return an
error when there was an error in a concurrent dlfcn function.
Renamed global static variables to have the "s" prefix.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9305 a95241bf-73f2-0310-859d-f6bbb57e9c96
same mechanism as NewOS, ie. using the iframe "stack" pointer (using the
new i386_get_current_iframe() function).
Implemented fork() support functions arch_{store|restore}_fork_frame().

team's address space - for internal use, anyway.
Added a ToDo: item to exec_team() to remind me of alarms and signals.
Started implementing fork_team() based on team_create_team() - it's not
completed (or even works), though.

Implemented _get_next_area_info() and _user_get_next_area_info().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9277 a95241bf-73f2-0310-859d-f6bbb57e9c96
reference to the address space, so that the calling team deletion function
doesn't have to do this.
delete_address_space() doesn't have to delete any areas anymore, since
at the point it's called, there is no area anymore, anyway: each area
holds a reference to the address space.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9276 a95241bf-73f2-0310-859d-f6bbb57e9c96
This actually reflects the only usage of this function anyway, and thus,
fixes the resize_area() function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9265 a95241bf-73f2-0310-859d-f6bbb57e9c96
vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.
This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Fixed some return types.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9264 a95241bf-73f2-0310-859d-f6bbb57e9c96
It currently checks for temporary caches, but it should really only be used
with regions for anonymous memory.
Fixed some return types.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9259 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

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.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9250 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed some return types.

file descriptors that have O_CLOEXEC set.
Minor cleanup.

back to load_container() so that map_image() has the chance to succeed.
The FATAL() macro now uses dprintf() instead of printf() when TRACE_RLD is defined.
Minor cleanup.

* Refactored common volume root to mount point resolution code into a
separate function.

As we currently don't have these environment variables set at init time, their values
are hardcoded for the moment.

could cause before.

The write functions didn't change the buffer address on a partial write
which could lead to corruption in the pipe data.

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
This fixes the build as unistd.h defined sleep() as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9108 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.
