load_kernel_add_on() now protects the text area read-only (theoretically,
as set_area_protection() has not yet been implemented).

only).
Userland segments are now called _seg0rw/_seg0ro.

Also made elf_lookup_symbol_address() less restrictive with respect to the
ELF symbol found (it now accepts all types, not only functions).

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.

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.

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".

to acquire the team spinlock).
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
Removed all old NewOS error codes.
Cleaned up the includes a bit.
Now prints out a list of preloaded images.

normal circumstances, though).
Updated the comment why we have to create the read-only segment as read-write.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5055 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented realloc().
Adapted all other sources, some minor cleanups in some files as well.

Also kernel/module.h was hidden by os/drivers/module.h - fixed; kernel/module.h
is now called kmodule.h and only contains the module_init() function for the
kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1122 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in module.c that I caused due to changes in the VFS.
Added the sys_write_link() call.

rel type (111) when it tried to load the PCI bus manager - I've only removed
the crash, but I didn't dig any deeper yet.
Note, this only happens using bochs - on a real computer, the kernel runs
obviously without any problems.

- if the path name exceeded about 56 bytes, the function would have seg-faulted
- the calculation to decide if there is an extra region for the bss needed was wrong -
that caused the kernel to be not able to load certain executables
Also, fixed a warning, and cleaned up the above mentioned function a bit, added
some more comments.

benaphores; benaphores aren't that beneficial in kernel land, the benaphores
are a way to reduce the number of kernel calls.
They can now only be released by the same thread who originally acquired it.
Included other changes geist (change 1499) did to a) fix some bugs, and
b) reflect the changes made to the mutexes.
Cleaned the files a bit up, all the commented dprintf()s in elf.c are now
deactivated through a macro.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@311 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed some bugs in fd.c (how many more bugs can be in a small file like this? :-).
Added the syscalls for sys_open_dir(), and sys_create_dir().
