Fix a problem whereby detaching a device that has open kevent
registrations can result in a UAF: When a device detaches, it
calls seldestroy(), which calls knote_fini(), and when that
returns, the softc that contained the selinfo and klist are freed.
However, any knotes that were registered still linger on with the
kq descriptor they're were associated with, and when the file
descriptors close, those knotes will be f_detach'd, which will
call into the driver instance that no longer exists.

Address this problem by adding a "foplock" mutex to the knote.
This foplock must be held when calling into filter_attach(),
filter_detach(), and filter_event() (XXX not filter_touch();
see code for details).  Now, in klist_fini(), for each knote
that is on the klist that's about to be blown away, acquire
the foplock, replace the knote's filterops with a do-nothing
stub, and release the foplock.

The end result is that:
==> The foplock ensures that calls into filter_*() will get EITHER
    the real backing object's filterops OR the nop stubs.
==> Holing the foplock across the filter_*() calls ensures that
    klist_fini() will not complete until there are no callers inside
    the filterops that are about to be blown away.

Add inline functions to manipulate the klists that link up knotes
via kn_selnext:

- klist_init()
- klist_fini()
- klist_insert()
- klist_remove()

These provide some API insulation from the implementation details of these
lists (but not completely; see vn_knote_attach() and vn_knote_detach()).
Currently just a wrapper around SLIST(9).

This will make it significantly easier to switch kn_selnext linkage
to a different kind of list.

add new knote_set_eof() and knote_clear_eof() functions that handle the
necessary locking and don't leak as many implementation details to modules.

Changes to make EVFILT_PROC MP-safe:

Because the locking protocol around processes is somewhat complex
compared to other events that can be posted on kqueues, introduce
new functions for posting NOTE_EXEC, NOTE_EXIT, and NOTE_FORK,
rather than just using the generic knote() function.  These functions
KASSERT() their locking expectations, and deal with other complexities
for each situation.

knote_proc_fork(), in particiular, needs to handle NOTE_TRACK, which
requires allocation of a new knote to attach to the child process.  We
don't want to be allocating memory while holding the parent's p_lock.
Furthermore, we also have to attach the tracking note to the child
process, which means we have to acquire the child's p_lock.

So, to handle all this, we introduce some additional synchronization
infrastructure around the 'knote' structure:

- Add the ability to mark a knote as being in a state of flux.  Knotes
  in this state are guaranteed not to be detached/deleted, thus allowing
  a code path drop other locks after putting a knote in this state.

- Code paths that wish to detach/delete a knote must first check if the
  knote is in-flux.  If so, they must wait for it to quiesce.  Because
  multiple threads of execution may attempt this concurrently, a mechanism
  exists for a single LWP to claim the detach responsibility; all other
  threads simply wait for the knote to disappear before they can make
  further progress.

- When kqueue_scan() encounters an in-flux knote, it simply treats the
  situation just like encountering another thread's queue marker -- wait
  for the flux to settle and continue on.

(The "in-flux knote" idea was inspired by FreeBSD, but this works differently
from their implementation, as the two kqueue implementations have diverged
quite a bit.)

knote_proc_fork() uses this infrastructure to implement NOTE_TRACK like so:

- Attempt to put the original tracking knote into a state of flux; if this
  fails (because the note has a detach pending), we skip all processing
  (the original process has lost interest, and we simply won the race).

- Once the note is in-flux, drop the kq and forking process's locks, and
  allocate 2 knotes: one to post the NOTE_CHILD event, and one to attach
  a new NOTE_TRACK to the child process.  Notably, we do NOT go through
  kqueue_register() to do this, but rather do all of the work directly
  and KASSERT() our assumptions; this allows us to directly control our
  interaction with locks.  All memory allocations here are performed with
  KM_NOSLEEP, in order to prevent holding the original knote in-flux
  indefinitely.

- Because the NOTE_TRACK use case adds knotes to kqueues through a
  sort of back-door mechanism, we must serialize with the closing of
  the destination kqueue's file descriptor, so steal another bit from
  the kq_count field to notify other threads that a kqueue is on its
  way out to prevent new knotes from being enqueued while the close
  path detaches them.

In addition to fixing EVFILT_PROC's reliance on KERNEL_LOCK, this also
fixes a long-standing bug whereby a NOTE_CHILD event could be dropped
if the child process exited before the interested process received the
NOTE_CHILD event (the same knote would be used to deliver the NOTE_EXIT
event, and would clobber the NOTE_CHILD's 'data' field).

Add a bunch of comments to explain what's going on in various critical
sections, and sprinkle additional KASSERT()s to validate assumptions
in several more locations.

- Rename kqueue_misc_lock -> kqueue_timer_lock, since EVFILT_TIMER is
  now its only user.  Also initialize it as IPL_SOFTCLOCK; there is no
  practical difference in how it operates (it is still an adaptive lock),
  but this serves as a visual reminder that we are interlocking against
  a callout.
- Add some comments that describe why we don't need to hold kqueue_timer_lock
  when detaching an EVFILT_TIMER due to guarantees made by callout_halt().
- Mark timer_filtops as MPSAFE.

Fix the locking around EVFILT_FS.  Previously, the code would walk the
fs_klist and take the kqueue_misc_lock inside the event callback.
However, that list can be modified by the attach and detach callbacks,
which could result in the walker stepping right off a cliff.

Instead, we give the fs_klist it's own lock, and hold it while we
call knote(), using the NOTE_SUBMIT protocol.  Also, fs_filtops
into vfs_syscalls.c so all of the locking logic is contained in one
file (there is precedence with sig_filtops).  fs_filtops is now marked
MPSAFE.

implement fo_restart hook for kqueue descriptors, so that close(2)
on the descriptor won't block indefinitely if other thread is currently
blocked on the same kqueue in kevent(2)

done similarily to pipes and sockets, i.e. using flag on the potentially
shared kqueue structure hooked off file_t - this is somewhat suboptimal
if the application dup(2)ped the descriptor, but this should be rare
enough to not really matter

usually this causes the kevent(2) to end up returning EBADF since
on the syscall restart the descriptor is not there anymore; if
dup(2)ped the kevent(2) call can continue successfully if the closed
kqueue descriptor was other than the one used for the kevent(2)
call

fix a race in kqueue_scan() - when multiple threads check the same
kqueue, it could happen other thread seen empty kqueue while kevent
was being checked for re-firing and re-queued

make sure to keep retrying if there are outstanding kevents even
if no kevent is found on first pass through the queue, and only
drop the KN_QUEUED flag and kq_count when actually completely done
with the kevent

change is inspired by the FreeBSD in-flux handling, but without
introducing the reference counting

Load struct filedesc::fd_dt with atomic_load_consume.

Exceptions: when fd_refcnt <= 1, or when holding fd_lock.

While here:

- Restore KASSERT(mutex_owned(&fdp->fd_lock)) in fd_unused.
  => This is used only in fd_close and fd_abort, where it holds.
- Move bounds check assertion in fd_putfile to where it matters.
- Store fd_dt with atomic_store_release.
- Move load of fd_dt under lock in knote_fdclose.
- Omit membar_consumer in fdesc_readdir.
  => atomic_load_consume serves the same purpose now.
  => Was needed only on alpha anyway.

From tedu at openbsd:

kevent validates that ident is a valid fd by getting the file. one sad
quirk: uint64 to int32 truncation can lead to false positives, and then
later in the array sizing code, very big mallocs panic the kernel.
add a check that the ident isn't larger than INT_MAX in the fd case.

PR/50730: Benny Siegert: Go kqueue test panics kernel.
- use a marker knote from the stack instead of allocating and freeing on
  each scan.
- add more KASSERTS
- introduce a KN_BUSY bit that indicates that the knote is currently being
  scanned, so that knote_detach does not end up deleting it when the file
  descriptor gets closed and we don't end up using/trashing free memory from
  the scan.

* Arrange for interfaces that create new file descriptors to be able to
  set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

    - Add F_DUPFD_CLOEXEC to fcntl(2).
    - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
    - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
      for socket(2) and socketpair(2).
    - Add new paccept(2) syscall that takes an additional sigset_t to alter
      the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
      SOCK_NONBLOCK.
    - Add new mode character 'e' to fopen(3) and popen(3) to open pipes
      and file descriptors for close on exec.
    - Add new kqueue1(2) syscall with a new flags argument to open the
      kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.

* Fix the system calls that take socklen_t arguments to actually do so.

* Don't include userland header files (signal.h) from system header files
  (rump_syscallargs.h).

* Bump libc version for the new syscalls.

Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags

Fix memory leak in sysctl_proc_corename().

COMPAT_LINUX: rework ptrace() locking, minimise differences between
different versions per-arch.

Note: while this change adds some formal cosmetics for COMPAT_DARWIN and
COMPAT_IRIX - locking there is utterly broken (for ages).

If a multithreaded app closes an fd while another thread is blocked in
read/write/accept, then the expectation is that the blocked thread will
exit and the close complete.
Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.
Also rename fo_abort() to fo_restart() (this used to be fo_drain()).

Rename fo_drain() to fo_abort(), 'drain' is used to mean 'wait for output
do drain' in many places, whereas fo_drain() was called in order to force
blocking read()/write() etc calls to return to userspace so that a close()
call from a different thread can complete.
In the sockets code comment out the broken code in the inner function,
it was being called from compat code.

More changes to improve kern_descrip.c.

- Avoid atomics in more places.
- Remove the per-descriptor mutex, and just use filedesc_t::fd_lock.
  It was only being used to synchronize close, and in any case we needed
  to take fd_lock to free the descriptor slot.
- Optimize certain paths for the <NDFDFILE case.
- Sprinkle more comments and assertions.
- Cache more stuff in filedesc_t.
- Fix numerous minor bugs spotted along the way.
- Restructure how the open files array is maintained, for clarity and so
  that we can eliminate the membar_consumer() call in fd_getfile().  This is
  mostly syntactic sugar; the main functional change is that fd_nfiles now
  lives alongside the open file array.

Some measurements with libmicro:

- simple file syscalls are like close() are between 1 to 10% faster.
- some nice improvements, e.g. poll(1000) which is ~50% faster.

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

File descriptor changes, discussed on tech-kern:

- Redo reference counting to be sane.  LWPs accessing files take a short
  term reference on the local file descriptor.  This is the most common
  case.  While a file is in a process descriptor table, a reference is
  held to the file.  The file reference count only changes during control
  operations like open() or close().  Code that comes at files from an
  unusual direction (i.e. foreign to the process) like procfs or sysctl
  takes a reference on the file (f_count), and not on a descriptor.

- Remove knowledge of reference counting and locking from most code that
  deals with files.

- Make the usual case of file descriptor lookup lockless.

- Make kqueue MP and MT safe. PR kern/38098, PR kern/38137.

- Fix numerous file handling bugs, and bugs in the descriptor code that
  affected multithreaded processes.

- Split descriptor system calls out into sys_descrip.c.

- A few stylistic changes: KNF, remove unused casts now that caddr_t is
  gone. Replace dumb gotos with loop control in a few places.

- Don't do redundant pointer passing (struct proc, lwp, filedesc *) unless
  the routine is likely to be inlined.  Most of the time it's about the
  current process.

- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32
  code.

- To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to
  kevent1 that points to functions that do the actual copyin/copyout
  operations.  This is similar to what was done in FreeBSD by Paul Saab.

- Add the COMPAT_NETBSD32 definitions and hooks.

Cloning cleanup:

2. add 2 new negative errno's to `officially' support the cloning hack:
    - EDUPFD (used to overload ENODEV)
    - EMOVEFD (used to overload ENXIO)
3. Created an fdclone() function to encapsulate the operations needed for
   EMOVEFD, and made all cloners use it.
4. Centralize the local noop/badop fileops functions to:
   fnullop_fcntl, fnullop_poll, fnullop_kqfilter, fbadop_stat

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff

at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through

Make sure knote is detached from watched process when it exits, to avoid
using already-freed memory under some circumstancies.

(this bug was not NetBSD specific)

some more comment indentation fixes
kfilter_register(): use free() instead of FREE() - the memory is allocated
	using malloc(), not MALLOC()
filt_procdetach(): fix the KASSERT() to not fire spuriously

no need to 'lock' the process in filt_procattach()/filt_procdetach() for now
	(XXXSMP comment added)
kqueue_poll(): no need to protect with splnet, KNOTE() is never called
	from interrupt context so far
knote_attach():
 * don't memcpy() old fdp->fd_knlist if it's NULL
 * use free() instead of FREE() for old fdp->fd_knlist - the memory
   is allocated using malloc(9)
make the indentation of comments less insane (brrrr)
g/c bogus ARGSUSED
add couple KASSERT()s

Add a filter which simulates seltrue() by setting kn->kn_data to 0,
and then saying "event is active".

Add a selnotify(), which does a selwakeup() + KNOTE(), rather than
requiring all callers to do both.

This may be a transitional step only, or it may stick.  I haven't
decided yet.

Sprinkle some const, and make a very tiny optimization to the lookup
of system-provided filters (the common case).

* update for differences between netbsd & freebsd WRT:
	- header files
	- struct locking
	- pool (& other memory) allocation
	- timeouts
* add kqueue_ioctl(), to support ioctl(2) operations on a kqueue fd.
* change the way that system filters are referenced to support name lookups
  and unimplemented (yet known about) filter types (such as EVFILT_AIO)
* add kfilter_register(9): register filter with given name to map to given
  filterops. filter must not exist
* add kfilter_unregister(9): unregister user filter
* add kfilter_byname(): lookup filter by name, which can be a system filter
  or a user-added filter
* add kfilter_byfilter(): lookup filter by filter number
* in kqueue_register(), use kfilter_byfilter() to determine filterops rather
  than using obscure ~ operation (which was now incorrect due to renumbering)
* cleanup whitespace, improve comments
* check return code of all copyouts()s
