riastradh | ctype(3): New environment variable LIBC_ALLOWCTYPEABUSE.
If set, this does not force the ctype(3) functions to crash when
passed invalid inputs -- instead, they will return nonsense results,
and possibly print warnings to stderr, as is their right in
implementing undefined behaviour.
The nature of the nonsense results is unspecified. Currently, is*()
will always return true (even if that leads to mutually contradictory
conclusions, like isalpha and isdigit, or isgraph and isblank), and
tolower/toupper() will always return EOF. But perhaps in the future
the results may be randomized.
This way, if an application like firefox crashes on ctype abuse, you
can opt to accept the consequences of nonsense results instead by
running `env LIBC_ALLOWCTYPEABUSE= firefox' until the application is
fixed.

riastradh | ctype(3): Disable guard page in static libc.
Adding the guard page may have overflown several small installation
media. Let's try to keep this case small.
Update the tests to detect the cases where we will be running against
a libc without a guard page on the LC_CTYPE=C tables, and skip
testing abuse detection when it would rely on the guard page.

This verifies that:
- arc4random zeroes its state and reseeds itself on fork
- arc4random reseeds itself on entropy consolidation (e.g., VM clone)
- arc4random falls back to global state if it can't allocate local
state because address space limits cause mmap to fail
NOTE: This adds a new libc symbol __arc4random_global, but it's in
the reserved namespace and only used by t_arc4random, so no libc
minor bump.

libc: Reintroduce getentropy.
This was introduced two years ago when the getrandom/getentropy API
question was still open, and removed because the discussion was
ongoing. Now getentropy is more widely adopted and soon to be in
POSIX. So reintroduce the symbol into libc since we'll be keeping it
anyway. Discussion of details of the semantics, as interpreted by
NetBSD, is ongoing, but the symbol needs to get in before the
netbsd-10 branch. The draft POSIX text is
(https://www.opengroup.org/austin/docs/austin_1110.pdf):
SYNOPSIS
#include <unistd.h>
int getentropy(void *buffer, size_t length);
DESCRIPTION
The getentropy() function shall write length bytes of data
starting at the location pointed to by buffer. The output
shall be unpredictable high quality random data, generated by
a cryptographically secure pseudo-random number
generator. The maximum permitted value for the length
argument is given by the {GETENTROPY_MAX} symbolic constant
defined in <limits.h>.
RETURN VALUES
Upon successful completion, getentropy() shall return 0;
otherwise, -1 shall be retunred and errno set to indicate the
error.
ERRORS
The getentropy() function shall fail if:
[EINVAL] The value of length is greater than
{GETENTROPY_MAX}.
The getentropy() function may fail if:
[ENOSYS] The system does not provide the necessary
source of entropy.
RATIONALE
The getentropy() function is not a cancellation point.
Minor changes from the previous introduction of getentropy into libc:
- Return EINVAL, not EIO, on buflen > 256.
- Define GETENTROPY_MAX in limits.h.
The declaration of getentropy in unistd.h and definition of
GETENTROPY_MAX in limits.h are currently conditional on
_NETBSD_SOURCE. When the next revision of POSIX is finalized, we can
expose them also under _POSIX_C_SOURCE > 20yymmL as usual -- and this
can be done as a pullup without breaking existing compiled programs.

No functional change intended, other than to expose new symbols --
just preparation to expose these to acpivmgenid(4), so it can use
these when the VM host notifies us that we, the guest, have been
cloned.

arc4random(3): Reseed if system entropy epoch changes.
This can happen, for example, if the system is a VM instance, and the
VM is cloned.
This incurs the cost of a system call on every arc4random call, which
is unfortunate, but
1. we don't currently have a (machine-independent) mechanism for
exposing a read-only page to userland shared by the kernel to
enable a cheaper access path to the entropy epoch; and
2. the algorithm here -- a simple application of ChaCha -- is likely
also a bottleneck and could be much cheaper by
(a) using sys/crypto/chacha for machine-dependent vectorized
ChaCha code, and
(b) filling a buffer (somewhere between a cipher block and a page)
in a batch at a time, instead of running ChaCha to generate
only 32 bytes at a time.
So although this might be a performance hit, the security benefit is
worthwhile and we have a clear path to do better than reversing the
performance hit later.
