d338200e2b libs/posix: Implemented new locale functions
Implemented the missing POSIX functions in <locale.h>:
newlocale, duplocale, uselocale, and freelocale, and also
provided missing type definitions for <locale.h>.

Implemented missing POSIX locale-based function variants.

Modified LocaleBackend so that it could support thread-local
locales.

Some glibc-like locale-related variables supporting
ctype and printf family of functions have also been updated
to reflect the thread-local variables present in the latest
glibc sources.

As there have been some modifications to global symbols
in libroot, libroot_stubs.c has been regenerated.

Bug: #17168

526669de6f system/kernel: Increase MAX_PROCESS_ARGS_SIZE; fixes #17612
* Resolves an issue compiling icu70
* FreeBSD is 262,144
* Linux is 2,097,152
* Haiku was 131,072

This roughly doubles the maximum args length, and makes us
function inline with FreeBSD today.  If we're the shortest
straw, we're going to find a lot of things broken (such
as ICU 70.1) Matching FreeBSD means any limitations we see
will also be seen on FreeBSD, making fewer "Haiku issues".

857c79a6b8 Introduce symbol_visibility.h with macros to define hidden functions
These were used in function_remapper.cpp but can be used elsewhere too,
so move them to a private header. Also use them for the stack protector
hidden function definition (probably not so useful since gcc2 doesn't
support using the stack protector anyway?).

The gcc2 way to make a symbol hidden is to manually generate the .hidden
directive in the assembler output. This is not perfect: it is hard to
use for C++ functions and methods (manual mangling of the name is
needed), and inline assembler can only be inserted inside functions. But
the alternative is patching gcc2 to add support for the function
attribute, and I don't want to dig into that today.

4986a9a3fd Revert "kernel: Remove the B_KERNEL_AREA protection flag."
This reverts parts of hrev52546 that removed the B_KERNEL_AREA
protection flag and replaced it with an address space comparison.

Checking for areas in the kernel address space inside a user address
space does not work, as areas can only ever belong to one address space.
This rendered these checks ineffective and allowed to unmap, delete or
resize kernel managed areas from their respective userland teams.

That protection was meant to be applied to the team user data area which
was introduced to reduce the kernel to userland overhead by directly
sharing some data between the two. It was intended to be set up in such
a manner that this is safe on the kernel side and the B_KERNEL_AREA flag
was introduced specifically for this purpose.

Incidentally the actual application of the B_KERNEL_AREA flag on the
team user data area was apparently forgotten in the original commit.

The absence of that protection allowed applications to induce KDLs by
modifying the user area and generating a signal for example.

This change restores the B_KERNEL_AREA flag and also applies it to the
team user data area.

kernel memory is.

which bits are allocated are which are unused.)

2c588b031f kernel: Properly separate and handle THREAD_BLOCK_TYPE_USER.
Consider this scenario:
 * A userland thread puts its ID into some structure so that it
   can be woken up later, sets its wait_status to initiate the
   begin of the wait, and then calls _user_block_thread.
 * A second thread finishes whatever task the first thread
   intended to wait for, reads the ID almost immediately
   after it was written, and calls _user_unblock_thread.
 * _user_unblock_thread was called so soon that the first
   thread is not yet blocked on the _user_block_thread block,
   but is instead blocked on e.g. the thread's main mutex.
 * The first thread's thread_block() call returns B_OK.
   As in this example it was inside mutex_lock, it thinks
   that it now owns the mutex.
 * But it doesn't own the mutex, and so (until yesterday)
   all sorts of mayhem and then a random crash occurs, or
   (after yesterday) an assert-failure is tripped that
   the thread does not own the mutex it expected to.

The above scenario is not a hypothetical, but is in fact the
exact scenario behind the strange panics in #15211.

The solution is to only have _user_unblock_thread actually
unblock threads that were blocked by _user_block_thread,
so I've introduced a new BLOCK_TYPE to differentiate these.
While I'm at it, remove the BLOCK_TYPE_USER_BASE, which was
never used (and now never will be.) If we want to differentiate
different consumers of _user_block_thread for debugging
purposes, we should use the currently-unused "object"
argument to thread_block, instead of cluttering the
relatively-clean block type debugging code with special
types.

One final note: The race condition which was the case of
this bug does not, in fact, imply a deadlock on the part
of the rw_lock here. The wait_status is protected by the
thread's mutex, which is acquired by both _user_block_thread
and _user_unblock_thread, and so if _user_unblock_thread
succeeds faster than _user_block_thread can initiate
the block, it will just see that wait_status is already
<= 0 and return immediately.

Fixes #15211.

475172337b headers/kernel: Move B_WAIT_TILL_LOADED to a syscall header.
It is only used as an argument to _kern_load_image directly, not to
any of the load_image functions in image.h, so it belongs in a syscall-
specific header like other such constants.

No functional change intended.
