capabilities to aid in debugging memory corruption issues.
It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees
It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.

now. The attribute directory, index directory, and query functions use the
the public POSIX API, so does the kernel module code. Those components were
not initializing the structure correctly anymore since the introduction of
telldir()/seekdir().

* As even the author of fs_attr.c was trying to use fs_write_attr() in an
unsupported way in the cp copy_attributes() implementation, try to be
more forgiving and support writing attributes at an offset. The method is
required to behave inconsistent in that replacing bytes at offset 0 is
not supported as replacing bytes at any other offset. Writing at offset 0
will clobber the existing attribute to stay compatible with BeOS.
NOTE: BFS itself still does not support writing attributes at an offset which
are withing the "small data section". To work around this problem, programs
which copy attributes in a loop must make sure that their buffer is large
enough that such "small data section" attributes require only one loop
iteration.

compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
(as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
stat_beos*, and and made it private. Added a new version (using up a
reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
for sake of binary compatibility. This breaks source compatibility, though,
which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
BRefFilter.

previous check didn't work since it used #if, not #ifdef).
* Also took the liberty to rename our boot loader to haiku_loader, since I had
to update the nasm binary anyway. Updated the assembly sources to nasm 2.0.
* I haven't found where the synth location in the MIDI code is specified,
though.
* Also, NetBootArchive, and FloppyBootImage haven't been updated yet. Will do
so next.
* Some optional packages still put their license to beos/etc/licenses. I didn't

we might want to introduce a common/data/licenses instead for those.

ported software:
* If the macro B_USE_POSITIVE_POSIX_ERRORS is defined the POSIX error code
constants (ENOMEM, EINTR,...) will have positive values.
* Introduced the macros B_TO_{POSITIVE,NEGATIVE}_ERROR() which do convert a
given error code to a positive/negative value.
* Added static library libposix_error_mapper.a that overrides all POSIX
functions (save the ones I forgot to add :-)) directly meddling with error
codes (having them as parameter or returning them) dealing with the
positive<->negative error code conversions. The functions have hidden
visibility, so they affect only the shared object they are linked into.
* So ideally all one has to do is to build a ported software with
-DB_USE_POSITIVE_POSIX_ERRORS and -lposix_error_mapper and be good with
respect to error code problems.
* Potential issues:
- When mixing ported and Haiku native code, i.e. using Haiku native code in
a ported software or using a ported library in a Haiku native application
care must be taken to convert error codes where the two interface. That's
what the B_TO_{POSITIVE,NEGATIVE}_ERROR() macros are supposed to be used
for.
- A ported static library can obviously not be linked directly against
-lposix_error_mapper. The shared object linking a against the ported static
library has to do that. The previous point applies when that causes mixing
with Haiku native code.
- When dependent ported libraries are used probably all of them should use
the error mapping.
Comments welcome.

the per-root-image breadth-first sorted image array. Instead we have a
per-image hook function to resolve the symbols. The default function
uses the sLoadedImages list directly, which is breadth-first sorted
anyway. There's also a BeOS function for old-style symbol resolution
and one for add-ons, which lacks a proper implementation yet (just
uses old-style ATM).
* Made the dl*() functions POSIX compliant:
- dlopen() does no longer use load_add_on(), but loads the object as a
library. It also properly supports a NULL name, now -- the previous
"_APP_" work-around did only work, if this soname was set on the
program (unlikely for programs using this API).
- Implemented RTLD_{GLOBAL,LOCAL}.
- dlsym() looks up symbols properly now, i.e. not just in the given
image, but breadth-first for an actual image or in load order for
the global scope. It also supports the not-quite POSIX RTLD_DEFAULT
and RTLD_NEXT extensions. Our RTLD_NEXT finds more symbols than in
Linux (also in later dlopen()ed libraries), but that should be fine.

This is an implementation taken from Wikipedia (declared as public domain

* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.

- *pathconf() now uses statvfs and fs_info data when appropriate. It should also check for file type though, some only apply to directory or others.
- added confstr(_CS_PATH) with a sensible default.

vm_page_write_modified_pages(), save that it only writes pages in the
given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.

* Made the pthread_cond_t internals public. This is necessary to support
process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
value. We do have a separate field in the _pthread_thread structure
for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
compatible.

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

particularly efficient.
* pthread_mutex implementation:
- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
still broken, since it doesn't work in C code.

arguments they get a single thread_creation_attributes structure now.
* Added stack_address and stack_size to thread_creation_attributes,
which allow to specify the stack size or the stack to be used for the
new user thread.

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

defined/undefined to numeric values (0 for undefined). This allows for
trace levels.
* Set SYSCALL_TRACING_IGNORE_KTRACE_OUTPUT default to 1, since this is
what one usually wants.

registrar provides access to the DBs via a port message based
protocol. The functions in libroot just ask the registrar now.
* Added Linuxish shadow passwd support. No putspent() though -- we'll
provide private functions.

that does not rely on the Be API TLS anymore, and is also more compliant
with respect to the lifespan of the key specific values.
* It supports up to 256 different keys, which is equivalent of the solution
that FreeBSD offers.
* The main thread now also gets a pthread_thread structure.
* Reenabled the POSIX suite test pthread_key_delete_2-1 as we now pass it.
* This also fixes bug #1642.

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

- Moved most file_system_module_info hooks into separate structures.
Those that operate on mounted volumes to fs_volume_ops, those
operating on a vnode to fs_vnode_ops.
- Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
again.
- Instead of a void* volume and node cookie hooks are passed a
fs_volume and fs_vnode structure pointer, which contain the cookie
and an ops pointer (fs_volume a few more things).
- The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
instead of the volume ID. So does vfs_get_fs_node_from_path().
- Added type and flags arguments to publish_vnode() and the
get_vnode() hook and removed the type argument from lookup() hook.
Added vnode::type using formerly unused bits to store the node type.
Simplified a few things in the VFS due to the now always available
node type.
- Added fs_volume_ops::{create,delete}_sub_vnode() and
fs_vnode_ops::get_super_vnode() hooks. They are used to support file
system layers, e.g. allowing to extend an FS not supporting BeOS
attribute with attribute support. Needs some more work in the VFS.
- Added fs_vnode_ops::create_special_node() hook for creating special
nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
changes. Removed all other FSs from the image for the time being.
We'll see whether further API changes are necessary before porting
them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
- Added syscall _kern_create_fifo() (used by mkfifo()), which creates
a special node (type S_IFIFO) in the respective file system.
- When a special node is published the VFS creates a respective sub
node. Currently only FIFOs are supported.
- Added a little support for FIFO subnodes by using functionality from
the pipefs.
- Added mkfifo to the image. It can create FIFOs in the rootfs, but
the FIFOs aren't really usable ATM, since they still work like
pipes, i.e. readers and writers need to have them open at the same
time.
* Some smaller changes in the VFS:
- Made the *_CALL macros nicer to use (vargs).
- Refactored FS entry lookup into new function lookup_dir_entry().
- create_vnode() no longer just calls the FS create() hook. First it
looks up the entry and uses open_vnode(), if it already exists. This
is necessary for two reasons: 1) The FS might not support create()
while still allowing to open() entries. 2) When the FS has other
layers on to of it (or the respective node) it might not be
responsible for opening the node.
