Both functions take a non-const parameter. Implementations may modify
the passed string, even though ours do not.

We need to test what the compiler supports, not what the C library
provides. This prevents static_assert from being defined when compiling
with the in-tree gcc (4.2.1) which does not support _Static_assert.

be 8 bytes in the 64-bit ABI just like in the 32-bit ABI. But that means
there is no "spare" word in the TCB that we can use to store a pointer
to our struct pthread. So we have to treat powerpc64 special.
Also recognize that the thread pointer points 0x7000 bytes after the TCB.
Since the TCB is 8 bytes this means that TCB_OFFSET should be 0x7008.

The API exposes controls of modern audio hardware and sndiod software
volume knobs in a uniform way. Hardware knobs are exposed through
sndiod. Multiple programs may use the controls at the same time
without the need to continuously scan the controls.
For now sndiod exposes only its own controls and the master output and
input volumes of the underlying hardware (if any), i.e. those
typically exposed by acpi volume keys.

- put functions and data which are only used before calling the executable's
start function into their own page-aligned segments for unmapping
(only done on amd64, arm64, armv7, powerpc, and sparc64 so far)
- pass .init_array and .preinit_array functions an addition argument which
is a callback to get a structure which includes a function that frees
the boot text and data
- sometimes delay doing RELRO processing: for a shared-object marked
DF_1_INITFIRST do it after the object's .init_array, for the executable
do it after the .preinit_array
- improve test-ld.so to link against libpthread and trigger its initialization

libs have it, it is a function that is considered harmful, so:
Delete malloc_usable_size(). It is a function that blurs the line
between malloc managed memory and application managed memory and
exposes some of the internal workings of malloc. If an application
relies on that, it is likely to break using another implementation
of malloc. If you want usable size x, just allocate x bytes. ok

to unveil. Unfortunately the auth subsystem uses _PATH_AUTHPROG =
"/usr/libexec/auth/login_", which it auth-program is appended to -- a
rather gross idea which now shows lack of wisdom.
|
|
This brings unveil into the tree, disabled by default - Currently
this will return EPERM on all attempts to use it until we are
fully certain it is ready for people to start using, but this
now allows for others to do more tweaking and experimentation.
Still needs to send the unveil's across forks and execs before
fully enabling.
Many thanks to robert@ and deraadt@ for extensive testing.

4.2 BSD takes a signal mask as argument while POSIX sigpause(int
sig) expects a single signal. Do not expose our traditional BSD
sigpause(3) to XPG/POSIX sources.

needs (looking at you sgi, but others required this before). This is for
the circumstances we need pagesize known at compile time, not getpagesize()
runtime. Use it for malloc storage sizes, for shm, and to set pthread stack
default sizes. The stack sizes were a mess, and pushing them towards
page-aligned is healthy move (which will also be needed by the coming
stack register checker)

pledge for a new execve image immediately upon start. Also introduces
"error" which makes violations return -1 ENOSYS instead of killing the

may be missing/ignoring syscall return values and would continue with
inconsistant state)

While it is not clear (to me) why that ports ends up with corrupted

on the stack instead of mallocing the list and move the APIs from libpthread
to libc so that they can be used inside libc.
Note: the standard was explicitly written to permit/support this
"macro with unmatched brace" style and it's what basically everyone
else already does. We xor the info with random cookies with a
random magic to detect/trip-up overwrites.
Major bump to both libc and libpthread due to the API move.

Complete in the sense that all POSIX *locale(3) and *_l(3) functions
are included, but in OpenBSD, we of course only really care about
