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

It replaces the existing pwcache.c functions user_from_uid(3) and
group_from_gid(3) with the pax equivalents. Adapted from NetBSD
(mycroft) changes from our own pax's cache.c. OK guenther@
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.

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
program ("error" may not be handed to a setuid/setgid program, which
may be missing/ignoring syscall return values and would continue with
inconsistant state)

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.

For the moment it only includes <sys/exec_elf.h> but the goal is to
stop pulling it directly and also replace <elf_abi.h> at least for
base applications.

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
LC_CTYPE and we only support ASCII and UTF-8.
With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.
OK kettenis@ dcoppa@, and guenther@ on an earlier version.
Riding guenther@'s libc/librthread major bump.
This gives fast access to the address on systems that implement
the UserLocal register. TCB caching is still used when running
in the single-threaded mode in order not to penalize old systems.
The kernel counterpart of this change must be in place before
using this diff!

Also change permissions of all symlinks, so they don't depend on the umask

and add prereq targets, so some header files are generated by BUILDUSER
during 'make prereq' instead of by root during 'make includes'.
Switch the order of 'make cleandir' and 'make includes' during 'make build'
so we don't generate many files twice.
Except for some machine@ symlinks from ${MACHINE}/stand, /usr/obj is now
clean from files generated by root during 'make build'. Those will be
cleaned up in a second step.

This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

the b* byte functions belong in strings.h, not string.h so break

This version of the function will always open the secure/shadow/master
password files. Soon, the regular variants of these functions will not.
(Intermixing shadow and regular gets a little weird; don't do that.)
Not using struct spwd and getspwnam functions to reduce churn in callers.
Should just be a one line diff in most places.

thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition. thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel(). Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.
Minor bump to both libc and libpthread: make sure you install a new kernel!
ok semarie@
which results in tame() code placements being much more recognizeable.
tame() can be moved to unistd.h and does not need cpp symbols to turn the
bits on and off. The resulting API is a bit unexpected, but simplifies the
mapping to enabling bits in the kernel substantially.
