By making the disk block parameter used by the libufs(3) sbread(3)
function visible, applications using sbread(3) can set their own
addition options such as using the STDSB_NOHASHFAIL request to
say that they want the superblock read to succeed even when
the superblock checkhash is incorrect.
While here also add an error message when a check-hash failure
is detected.
Now that we version symbols we should bump the library major version.
While here use version FBSD_1.7 to match the current HEAD FreeBSD
namespace and remove extraneous 'All rights reserved' and incorrect

The manual page of gmirror describes how gmirror providers can be used
for kernel dumps. Unfortunately, the instruction references
/etc/rc.early, which is no longer a part of rc(8).
Remove references to rc.early and suggest creating an rc(8) service
script instead.
Future work: In the Problem Report on Bugzilla, Lawrence Chen suggested
adding example rc(8) scripts to the gmirror. However, those examples
need to be tested before they become official reference examples in the
base. Also, those scripts should probably land directly to /etc/rc.d,
/usr/share/examples/rc.d, or /usr/share/examples/gmirror instead of the
gmirror manual page.

libnv and libnvpair have aliased symbols, and as a result a single process which
dlopens a shared object that is dynamically linked to libnv and another to
libnvpair will wind up with a single set of resolved symbols for those in
conflict. A source file also cannot include both libnv and libnvpair headers
because of aliased identifiers. To resolve the situation, libnv types and
functions are namespaced via nv_namespace.h, and libnv symbols are
versioned. The msgio functions are not namespaced or exported as they are not
part of the external API.

Currently the cuse(3) mmap(2) offset is split into 128 banks of 16 Mbytes.
Allow cuse(3) to make allocations that span multiple banks at the expense
of any fragmentation issues that may arise. Typically mmap(2) buffers are
well below 16 Mbytes. This allows 8K video resolution to work using webcamd.

Historically, GEOM utilities (gpart(8), gstripe(8), gmirror(8),
etc) used the gctl_error() routine to report errors. If they called
gctl_error() they would exit with EXIT_FAILURE, otherwise they would
return with EXIT_SUCCESS. If they used gctl_error() to output an
informational message, for example when run with the -v (verbose)
option, they would mistakenly exit with EXIT_FAILURE. A further
limitation of the gctl_error() function was that it could only be
called once. Messages from any additional calls to gctl_error()
would be silently discarded.
To resolve these problems a new function, gctl_msg() has been added.
It can be called multiple times to output multiple messages. It
also has an additional errno argument which should be zero if it is
an informational message or an errno value (EINVAL, EBUSY, etc) if
it is an error. When done the gctl_post_messages() function should
be called to indicate that all messages have been posted. If any
of the messages had a non-zero errno, the utility will EXIT_FAILURE.
If only informational messages (with zero errno) were posted, the
utility will EXIT_SUCCESS.

Since https://github.com/llvm/llvm-project/commit/ca75ac5f04f2, clang 15
has a new warning about _Generic selection expressions, such as used in
math.h:
lib/libc/gdtoa/_ldtoa.c:82:10: error: due to lvalue conversion of the controlling expression, association of type 'volatile float' will never be selected because it is qualified [-Werror,-Wunreachable-code-generic-assoc]
switch (fpclassify(u.e)) {
^
lib/msun/src/math.h:109:2: note: expanded from macro 'fpclassify'
__fp_type_select(x, __fpclassifyf, __fpclassifyd, __fpclassifyl)
^
lib/msun/src/math.h:85:14: note: expanded from macro '__fp_type_select'
volatile float: f(x), \
^
This is because the controlling expression always undergoes lvalue
conversion first, dropping any cv-qualifiers. The 'const', 'volatile',
and 'volatile const' associations will therefore never be used.

These are all "standard microarchitectural events", which in theory are
supported by every ARMv8 processor. In practice, it depends on the
pmu-event definitions being complete and accurate, which they are not
for every processor. Still, these aliases should be functional on the

Instead of returning EMSGSIZE pass the error code from fdallocn() directly
to userland. That would be EMFILE, which makes much more sense. This
error code is not listed in the specification[1], but the specification
doesn't cover such edge case at all. Meanwhile the specification lists
EMSGSIZE as the error code for invalid value of msg_iovlen, and FreeBSD
follows that, see sys_recmsg(). Differentiating these two cases will make
a developer/admin life much easier when debugging.
