e8ee7d9035 correct readlinkat(2) return type
r176215 corrected readlink(2)'s return type and the type of the last
argument.  readlink(2) was introduced in r177788 after being developed
as part of Google Summer of Code 2007; it appears to have inherited the
wrong return type.

Man pages and header files were already ssize_t; update syscalls.master
to match.

Have ogetkerninfo, ogetpagesize, ogethostname, osethostname, and oaccept
declare o<foo>_args structs rather than non-compat ones. Due to a
failure to use NOARGS in most cases this adds only one new declaration.

No changes required in freebsd32 as only ogetpagesize() is implemented
and it has a 32-bit specific implementation.

9a38df59e9 Fix freebsd32 mknod(at).
As dev_t is now a 64-bit integer, it requires special handling as a
system call argument.  64-bit arguments are split between two 64-bit
integers due to the way arguments are promoted to allow reuse of most
system call implementations.  They must be reassembled before use.
Further, 64-bit arguments at an odd offset (counting from zero) are
padded and slid to the next slot on powerpc and mips.  Fix the
non-COMPAT11 system call by adding a freebsd32_mknodat() and
appropriately padded declerations.

The COMPAT11 system calls are fully compatible with the 64-bit
implementations so remove the freebsd32_ versions.

Use uint32_t consistently as the type of the old dev_t.  This matches
the old definition.

The restruct qualifier is intended to aid code generation in the

structs using copyin/copyout and the like which can not be written in C

46e2054905 Mark various removed system calls as OBSOL instead of UNIMPL.
This is mostly a cosmetic change except that obsolete system calls are
assigned meaningful names in the names arrays which means that using
tools like kdump or truss against binaries invoking these system calls
will print out the name instead of the number.  The script I use to
generate the XML list of syscalls for GDB also ignores UNIMPL but not
OBSOL entries.  In general UNIMPL should only be used to reserve
placeholders for system calls that have never been implemented while
system calls that existed at one time in FreeBSD but were removed
should be marked OBSOL instead.

9f9c9b22ec Reimplement brk() and sbrk() to avoid the use of _end.
Previously, libc.so would initialize its notion of the break address
using _end, a special symbol emitted by the static linker following
the bss section.  Compatibility issues between lld and ld.bfd could
cause the wrong definition of _end (libc.so's definition rather than
that of the executable) to be used, breaking the brk()/sbrk()
interface.

Avoid this problem and future interoperability issues by simply not
relying on _end.  Instead, modify the break() system call to return
the kernel's view of the current break address, and have libc
initialize its state using an extra syscall upon the first use of the
interface.  As a side effect, this appears to fix brk()/sbrk() usage
in executables run with rtld direct exec, since the kernel and libc.so
no longer maintain separate views of the process' break address.

added annotations to COMPAT* syscalls and is using them in a record and
playback framework.  One can envision other uses such as a WITNESS-like
validator for copyin/out as speculated on in the review.

As this time we are only annotating sys/kern/syscalls.master as that is
sufficient for userspace work.  If kernel use cases materialize, we can
annotate other syscalls.master as needed.

e9ac27430c Implement getrandom(2) and getentropy(3)
The general idea here is to provide userspace programs with well-defined
sources of entropy, in a fashion that doesn't require opening a new file
descriptor (ulimits) or accessing paths (/dev/urandom may be restricted
by chroot or capsicum).

getrandom(2) is the more general API, and comes from the Linux world.
Since our urandom and random devices are identical, the GRND_RANDOM flag
is ignored.

getentropy(3) is added as a compatibility shim for the OpenBSD API.

truss(1) support is included.

Tests for both system calls are provided.  Coverage is believed to be at
least as comprehensive as LTP getrandom(2) test coverage.  Additionally,
instructions for running the LTP tests directly against FreeBSD are provided
in the "Test Plan" section of the Differential revision linked below.  (They
pass, of course.)

2b34e84335 Add abstime kqueue(2) timers and expand struct kevent members.
This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which
specifies that the data field contains absolute time to fire the
event.

To make this useful, data member of the struct kevent must be extended
to 64bit.  Using the opportunity, I also added ext members.  This
changes struct kevent almost to Apple struct kevent64, except I did
not changed type of ident and udata, the later would cause serious API
incompatibilities.

The type of ident was kept uintptr_t since EVFILT_AIO returns a
pointer in this field, and e.g. CHERI is sensitive to the type
(discussed with brooks, jhb).

Unlike Apple kevent64, symbol versioning allows us to claim ABI
compatibility and still name the new syscall kevent(2).  Compat shims
are provided for both host native and compat32.

6992112349 Commit the 64-bit inode project.
Extend the ino_t, dev_t, nlink_t types to 64-bit ints.  Modify
struct dirent layout to add d_off, increase the size of d_fileno
to 64-bits, increase the size of d_namlen to 16-bits, and change
the required alignment.  Increase struct statfs f_mntfromname[] and
f_mntonname[] array length MNAMELEN to 1024.

ABI breakage is mitigated by providing compatibility using versioned
symbols, ingenious use of the existing padding in structures, and
by employing other tricks.  Unfortunately, not everything can be
fixed, especially outside the base system.  For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.

Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.

Struct xvnode changed layout, no compat shims are provided.

For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful
than reporting 64-bit dev_t, for the sake of pstat.

Update note: strictly follow the instructions in UPDATING.  Build
and install the new kernel with COMPAT_FREEBSD11 option enabled,
then reboot, and only then install new world.

Credits: The 64-bit inode project, also known as ino64, started life
many years ago as a project by Gleb Kurtsou (gleb).  Kirk McKusick

bb430bc740 Fully handle size_t lengths in AIO requests.
First, update the return types of aio_return() and aio_waitcomplete() to
ssize_t.

POSIX requires aio_return() to return a ssize_t so that it can represent
all return values from read() and write().  aio_waitcomplete() should use
ssize_t for the same reason.

aio_return() has used ssize_t in <aio.h> since r31620 but the manpage and
system call entry were not updated.  aio_waitcomplete() has always
returned int.

Note that this does not require new system call stubs as this is
effectively only an API change in how the compiler interprets the return
value.

Second, allow aio_nbytes values up to IOSIZE_MAX instead of just INT_MAX.

aio_read/write should now honor the same length limits as normal read/write.

Third, use longs instead of ints in the aio_return() and aio_waitcomplete()
system call functions so that the 64-bit size_t in the in-kernel aiocb
isn't truncated to 32-bits before being copied out to userland or
being returned.

Finally, a simple test has been added to verify the bounds checking on the
maximum read size from a file.

399e8c1773 Simplify AIO initialization now that it is standard.
- Mark AIO system calls as STD and remove the helpers to dynamically
  register them.
- Use COMPAT6 for the old system calls with the older sigevent instead of
  an 'o' prefix.
- Simplify the POSIX configuration to note that AIO is always available.
- Handle AIO in the default VOP_PATHCONF instead of special casing it in
  the pathconf() system call.  fpathconf() is still hackish.
- Remove freebsd32_aio_cancel() as it just called the native one directly.
