thorpej a792b8435e Improvements to the problib(3) API:
==> Provide a much more complete set of setters and getters for different
    value types in the prop_array_util(3) and prop_dictionary_util(3)
    functions.

==> Overhaul the prop_data(3), prop_number(3), and prop_string(3) APIs
    to be easier to use and less awkwardly named,  Deprecate the old
    awkward names, and produce link-time warnings when they are referenced.

==> Deprecate mutable prop_data(3) and prop_string(3) objects.  The old
    APIs that support them still exist, but will now produce link-time
    warnings when used.

==> When the new prop_string(3) API is used, strings are internally
    de-duplicated as a memory footprint optimization.

==> Provide a rich set of bounds-checked gettter functions in and a
    corresponding set of convenience setters in the prop_number(3) API.

==> Add a new prop_bool_value(3) function that is equivalent to
    prop_bool_true(3), but aligned with the new "value" routines in
    prop_data(3), prop_string(3), and prop_number(3).

rin 3a564f248f Add m68k assembler version of __muldi3().
This is intended for 68060:
  - GCC does not emit __muldi3() for 68020-40, that have 32 * 32 --> 64 mulul
  - mulsl (and moveml), used in this code, are not implemented for 68010

In comparison with that from compiler_rt, this version saves:
  - 12% of processing time
  - 12 bytes of stack
  - 50 bytes of code size
Also, slightly faster, memory saving, and smaller than libgcc version.

By examining with evcnt(9), __muldi3() is invoked more than 1000 times per
sec by kernel, which should justify to introduce assembler version of this
function.

riastradh 5084c1b50f Rewrite entropy subsystem.
Primary goals:

1. Use cryptography primitives designed and vetted by cryptographers.
2. Be honest about entropy estimation.
3. Propagate full entropy as soon as possible.
4. Simplify the APIs.
5. Reduce overhead of rnd_add_data and cprng_strong.
6. Reduce side channels of HWRNG data and human input sources.
7. Improve visibility of operation with sysctl and event counters.

Caveat: rngtest is no longer used generically for RND_TYPE_RNG
rndsources.  Hardware RNG devices should have hardware-specific
health tests.  For example, checking for two repeated 256-bit outputs
works to detect AMD's 2019 RDRAND bug.  Not all hardware RNGs are
necessarily designed to produce exactly uniform output.

ENTROPY POOL

- A Keccak sponge, with test vectors, replaces the old LFSR/SHA-1
  kludge as the cryptographic primitive.

- `Entropy depletion' is available for testing purposes with a sysctl
  knob kern.entropy.depletion; otherwise it is disabled, and once the
  system reaches full entropy it is assumed to stay there as far as
  modern cryptography is concerned.

- No `entropy estimation' based on sample values.  Such `entropy
  estimation' is a contradiction in terms, dishonest to users, and a
  potential source of side channels.  It is the responsibility of the
  driver author to study the entropy of the process that generates
  the samples.

- Per-CPU gathering pools avoid contention on a global queue.

- Entropy is occasionally consolidated into global pool -- as soon as
  it's ready, if we've never reached full entropy, and with a rate
  limit afterward.  Operators can force consolidation now by running
  sysctl -w kern.entropy.consolidate=1.

- rndsink(9) API has been replaced by an epoch counter which changes
  whenever entropy is consolidated into the global pool.
  . Usage: Cache entropy_epoch() when you seed.  If entropy_epoch()
    has changed when you're about to use whatever you seeded, reseed.
  . Epoch is never zero, so initialize cache to 0 if you want to reseed
    on first use.
  . Epoch is -1 iff we have never reached full entropy -- in other
    words, the old rnd_initial_entropy is (entropy_epoch() != -1) --
    but it is better if you check for changes rather than for -1, so
    that if the system estimated its own entropy incorrectly, entropy
    consolidation has the opportunity to prevent future compromise.

- Sysctls and event counters provide operator visibility into what's
  happening:
  . kern.entropy.needed - bits of entropy short of full entropy
  . kern.entropy.pending - bits known to be pending in per-CPU pools,
    can be consolidated with sysctl -w kern.entropy.consolidate=1
  . kern.entropy.epoch - number of times consolidation has happened,
    never 0, and -1 iff we have never reached full entropy

CPRNG_STRONG

- A cprng_strong instance is now a collection of per-CPU NIST
  Hash_DRBGs.  There are only two in the system: user_cprng for
  /dev/urandom and sysctl kern.?random, and kern_cprng for kernel
  users which may need to operate in interrupt context up to IPL_VM.

  (Calling cprng_strong in interrupt context does not strike me as a
  particularly good idea, so I added an event counter to see whether
  anything actually does.)

- Event counters provide operator visibility into when reseeding
  happens.

rin 27f1060c62 Restrict usage of m68k assembler versions of {,u}divsi3 and {,u}divsi3 to
kernel and bootloader for 68010.

They requires a special calling convention to udivsi3, and cannot to be
mixed up in normal routines provided by libgcc or compiler_rt. Although,
there's no problem for using them in a controlled situation, i.e., kernel
and standalone programs.

Note that this does not affect at all m68k ports other than sun2, since
codes generated by gcc do not call these routines.

Assembler files are moved from common/lib/libc/arch/m68k/gen to
sys/lib/libkern/arch/m68k in order not to be compiled in libc.

rin fd255ae543 Implement workaround for IBM405 Errata 77 (aka CPU_210), where
interrupted stwcx. may errantly write data to memory:

    https://elinux.org/images/1/1d/Ppc405gp-errata.pdf

This is because stwcx. is split into two pieces in the pipeline.

We need to
(1) insert dcbt before every stwcx. instruction, as well as
(2) insert sync before every rfi/rfci instruction.

It is unclear which processors are affected, but according to Linux,
all 405-based cores up until 405GPR and 405EP are affected:

    https://github.com/torvalds/linux/blob/master/arch/powerpc/platforms/40x/Kconfig#L140

For kernel, this workaround can be restricted to affected processors.
However, for kernel modules and userland, we have to enable it for all
32bit powerpc archs in order to share common binaries as before.

fox 819b6be2db common/lib/libc/stdlib: Fix possible signed integer overflow.
common/lib/libc/stdlib/random.c:482:6 can result in signed integer overflow.

This bug was reported by UBSan runs.

The change has been tested using the following program to generate random numbers
in both the old and the new library and can be used to verify the correctness of the
library after the change.

#include <stdio.h>
#include <stdlib.h>

#define COUNT 1000 * 1000

int
main(void)
{
        int i;
        FILE *fp = fopen("numbers.txt", "w");

        srandom(0xdeadbeef);

        for(i = 0; i < COUNT; i++) {
                fprintf(fp, "%ld\n", random());
        }

        fclose(fp);

        return 0;

alternative is to parse the printf format manually to determine
which modifier to apply which would make this transparent to the
user (they could still always use '%u' or '%x'), but that's too
painful.

attempt to make the broken mman.h usage work (and did, but not the way
it should be done).   Also, after using the new * format (instead of only
when something has already matched) skip the associated data so we don't
attempt to interpret it as more field specifiers.  This func needs lots of TLC!

exactly like f format, and has data after the field specifier.  It doesn't.

kamil aee9a63f2a Tidy up the comment in ubsan.c
As noted, style has no impact on the comparison of a similar code.
This version is a reimplementation from scratch with no code and no
algirithm (whenever possible) reuse.

Public symbols and struct layout must be kept in sync with the code
generation part. It casues violation of the style like with long filenames.

My previous comment was 'too perfect' and could trigger some unnecessary
attention.

kamil 9aff107674 Import micro-UBSan (ubsan.c)
This is a reimplementation of the Undefined Behavior Sanitizer with the
following properties:
 - pure and clean-room C implementation,
 - no -fsanitize=vpts support, as it requires RTTI support and C++
   low-level routies to validate whether C++ objects are compatible
 - designed to be used inside libc and known as uUBSan or user-UBSan
 - designed to be shared with kernel and known as kUBSan or kernel-UBSan
 - designed to be usable with ATF tests as a standalone runtime,
   reachable without any MK* switches
 - designed to be safer for hardening as it does not have side effects on
   executables like writing to a selected location on demand
 - controllable with environment variable LIBC_UBSAN with options:
   * a - abort on report
   * A - do not abort on a report (unless a failure is unrecoverable)
   * e - output report to stderr
   * E - do not output report on stderr
   * l - output report on syslog (LOG_DEBUG | LOG_USER)
   * L - do not output report on syslog
   * o - output report on stdout
   * O - do not output report on stdout
   The default options are: "AeLO".
 - compatible with Clang (3.8, 7.x) and GCC (6.x) code generation
 - all handlers (except =vptr) from Clang/LLVM up to 7svn are supported

Tested with Clang amd64+i386 and GCC amd64+i386.

kamil c5b83981a9 Add bunch of missing includes of namespace.h in libc
The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

This change eliminates usage of the global changes of the following symbols:
 - strlcat -> _strlcat
 - sysconf -> __sysconf
 - closedir -> _closedir
 - fparseln -> _fparseln
 - kill -> _kill
 - mkstemp -> _mkstemp
 - reallocarr -> _reallocarr
 - strcasecmp -> _strcasecmp
 - strncasecmp -> _strncasecmp
 - strptime -> _strptime
 - strtok_r -> _strtok_r
 - sysctl -> _sysctl
 - dlopen -> __dlopen
 - dlclose -> __dlclose
 - dlsym -> __dlsym

The rev 1.4 changelog:
> Disable a sanity check output buffer != NULL in _STANDALONE case.
> Some kernels are loaded at address 0x0 by bootloaders and
> output buffer address could be zero in such case.
>
> Fixes "read text" errors on loading install floppy of NetBSD/news68k 4.0,
> reported by KIYOHARA Takashi on port-news68k.

This problem may also affect other m68k ports which use a gzipped install
kernel and kernel text address located at PA 0x0.

Also, use Xr to refer problib(3) in the HISTORY section instead of Nm.

While parsing the man pages, any .Nm occurrence gets replaced by the
value specified in the NAME section. Referencing individual function
names with .Nm was causing makemandb(8) to replicate the complete
