718a31be31 posix_fallocate.2: add an EINVAL errno case
As of r325320 posix_fallocate returns EINVAL on ZFS to indicate that
the underlying filesystem does not support this operation, per
POSIX.1-2008. Document this case in the man page.

LTO-8 Type M (also known as M8) is a pristine LTO-7 cartridge
formatted in a LTO-8 drive in a new, higher density format.  It
has a separate density code, and is only readable in an LTO-8

3f684c7c73 While discussing the new gets_s.c in D12785, ed@ suggested putting
{}'s around the if (c == EOF) block to prevent potential 'trailing else'
issues from being introduced when refactoring. As my gets_s() code
is based on this, it makes sense to fix the same issue here first
here and now, then do an svn copy again to capture this history).

981dd2aa38 Fix out-of-bounds read in libc/regex.
The bug is an out-of-bounds read detected with address sanitizer that
happens when 'sp' in p_b_coll_elems() includes NUL byte[s], e.g. if it's
equal to "GS\x00". In that case len will be equal to 4, and the
strncmp(cp->name, sp, len) call will succeed when cp->name is "GS" but the
cp->name[len] == '\0' comparison will cause the read to go out-of-bounds.

Checking the length using strlen() instead eliminates the issue.

The bug was found in LLVM with oss-fuzz:

82ffa91f39 Introduce caspermocks.
The idea behinds mocks is that we don't need to ifdef a lot of code in
tools itself but those defines are hidden in the casper library.
Right now the mocks are implemented as define/inlines functions.
There was a very long discussion how this should be implemented.
This approach has some advantages like we don't need to link to any additional
libraries. Unfortunately there are also some disadvantages for example it is
easy to get library out of sync between two versions of functions or that we
need extra define to compile program with casper support.
This isn't an ideal solution but it's good enough for now and should simplify
capsicumizing programs. This also doesn't close us any other ways to do those
mocks and this should evolve in time.

d4f614fd9c Remove artificial restriction on lio_listio's operation count
In r322258 I made p1003_1b.aio_listio_max a tunable. However, further
investigation shows that there was never any good reason for that limit to
exist in the first place. It's used in two completely different ways:

* To size a UMA zone, which globally limits the number of concurrent
  aio_suspend calls.

* To artifically limit the number of operations in a single lio_listio call.
  There doesn't seem to be any memory allocation associated with this limit.

This change does two things:

* Properly names aio_suspend's UMA zone, and sizes it based on a new constant.

* Eliminates the artifical restriction on lio_listio. Instead, lio_listio
  calls will now be limited by the more generous max_aio_queue_per_proc. The
  old p1003_1b.aio_listio_max is now an alias for
  vfs.aio.max_aio_queue_per_proc, so sysconf(3) will still work with
  _SC_AIO_LISTIO_MAX.
