Axel Dörfler 577402ea7e We now have text_region and data_region instead of the unclear array.
load_kernel_add_on() now protects the text area read-only (theoretically,
as set_area_protection() has not yet been implemented).

Axel Dörfler c9a96524d2 Modified load_kernel_add_on() to use the new address range reservation functions.

Axel Dörfler 3c20ebe8d7 Unified kernel loader area names (they now use "_text", and "_data" suffixes
only).
Userland segments are now called _seg0rw/_seg0ro.

Axel Dörfler ee7e4109ad Removed REGION_WIRING_* and REGION_ADDR_* and replaced them by their
BeOS counterparts.

Axel Dörfler 755b059fc1 Doh, Elf32_Word is unsigned, so st_size cannot go below zero.
Also made elf_lookup_symbol_address() less restrictive with respect to the
ELF symbol found (it now accepts all types, not only functions).

Axel Dörfler 6444e8f7bf Copied boot loader code to load symbol table into kernel as well - not yet
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.

Axel Dörfler bc6ab31951 (Almost) removed special handling of the kernel image, as it's now
maintained in a preloaded_image as well.

Axel Dörfler 52823d0c3d Added debugger command for dumping all symbols of the specified kernel image.
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.

Axel Dörfler 8590e919fc Now maintains the new preloaded_image::id field.
If an image cannot be created out of a preloaded_image, its resources
are freed now.

Axel Dörfler b918b5035f Bye, bye elf_lookup_symbol(), hello get_image_symbol().
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.

Axel Dörfler 81c323a767 unregister_elf_image() didn't call unregister_image(), so images never got
unregistered.

Axel Dörfler a364fba7d4 Is now using a hash for the images instead of a singly linked list.
Now registers its images as it should do (so you can use commands like
listimage in userland).
Added new debugger command "image".

Axel Dörfler 11a5baaf67 Updated the private kernel image API to be more efficient (no longer needs
to acquire the team spinlock).
Renamed the user syscalls to the new style.

Axel Dörfler fd1f6b7f01 Fixed a bug in elf_load_kspace(): the image structure and the pheaders were
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.

Axel Dörfler caa910df64 Changed some function return codes to return a status_t where appropriate.

Cleaned up the includes a bit.
Now prints out a list of preloaded images.

Axel Dörfler b858732b90 Fixed a scoping bug in the elf_load_kspace() function (non-critical under
normal circumstances, though).
Updated the comment why we have to create the read-only segment as read-write.

Axel Dörfler 633275adee Fixed some int/int32/status_t issues.
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.

Added the sys_write_link() call.

Axel Dörfler c2f9230c91 For some strange reason, elf_relocate_rel() crashed and reported a high
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.

Axel Dörfler 7d141659a6 Fixed some crucial bugs in the elf_load_uspace() function:
- 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.

lillo 3cfbecf1a6 First round of big changes: the term team has replaced proc all over the kernel, the few kern_* syscalls have been renamed to sys_* for consistency, and other small changes. The ps app is temporarily disabled until get_next_team_info is implemented.

Axel Dörfler 4bb2d8915b Implemented geist's recent change to mutexes - they are now no longer
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.
