sys/rwlock.h: Make this more self-contained for bool.

machine/mutex.h: Sprinkle includes so this can be used by crash(8).

ddb: New `show all tstiles' command.
Shows who's waiting for which locks and what the owner is up to.

Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE

sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>.

And thus out of <sys/param.h>, which is exceedingly overused and
fragile and delenda est.

Should fix (some) issues with the recent inclusion of machine/lock.h
in various machine/mutex.h files.

arm/mutex.h: Need machine/intr.h, machine/lock.h.

For ipl_cookie_t and __cpu_simple_lock_t.
evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.

Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which
should really be fixed.
opencrypto/cryptodev.h: Fix includes.
- Move sys/condvar.h under #ifdef _KERNEL.
- Add some other necessary includes and forward declarations.
- Sort.

hp300/intr.h: Fix missing includes.
linux/idr.h: Need <sys/mutex.h> for kmutex_t.
amiga/intr.h: Don't define spl*() functions if !_KERNEL.

This is used by crash(8) now, and what's important is ipl_cookie_t.
cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8).
cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.

Probably not necessary but let's be a little more cautious about
this.

atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).

arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.

Nix machine/param.h -- not meant to be used directly, pulled in by
sys/param.h.

Move the definition of ipl_cookie_t out of the kernel-only sections,
some _KMEMUSER applications need it.

ddb: Cast pointer to uintptr_t first before db_expr_t.

hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

news68k/intr.h: Fix includes.  Put some definitions under _KERNEL.

next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.

sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.

Make ipl_cookie_t visible for _KMEMUSER userland applications.

fix editor mishap in previous

Explicitly include <sys/mutex.h> for kmutex_t.

Replace kmutex_t * (which may be undefined here) with struct kmutex *,
suggested by Taylor.

hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).

mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
Make inclusion of sys/intr.h explicit for spl*.

fix hppa and vax builds.

machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in
sys/types.h.  avoids cpu_data.h vs sched.h include order issues.

move the hppa ipl_t typedef with the moved usage of it.
machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.

Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h.  And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.

ddb: Cast pointer to uintptr_t, then to db_expr_t.
Avoids warnings about conversion between pointer and integer of
different size on some architectures.

re-fix hppa builds.

this file uses __cpu_simple_lock(), not just the underlying type,
so it does need machine/lock.h.

Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h

But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex.  Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.

Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT.  Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.

ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.

explicitly include no longer implicitly included sys/mutex.h.

arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz.
Sidesteps namespace collision with `#define bits ...' in net/zlib.c.

complete the previous - there were two calls to find_first_bit() to fix.

arm/xscale: Missed a spot with previous find_first_bit commit.

evbarm/g42xxeb: Fix off-by-one in previous.

The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x),
which is equivalent to fls32(x) - 1, not to fls32(x).

Note that fls32 is 1-based and returns 0 for x=0.

Add containment for the cloning devices hack in vn_open.

Cloning devices (and also things like /dev/stderr) work by allocating
a struct file, stuffing it in the file table (which is a layer
violation), stuffing the file descriptor number for it in a magic
field of struct lwp (which is gross), and then "failing" with one of
two magic errnos, EDUPFD or EMOVEFD.

Before this commit, all callers of vn_open in the kernel (there are
quite a few) were expected to check for these errors and handle the
situation. Needless to say, none of them except for open() itself did,
resulting in internal negative errnos being returned to userspace.

This hack is fairly deeply rooted and cannot be eliminated all at
once. This commit adds logic to handle the magic errnos inside
vn_open; now on success vn_open returns either a vnode or an integer
file descriptor, along with a flag that says whether the underlying
code requested EDUPFD or EMOVEFD. Callers not prepared to cope with
file descriptors can pass NULL for the extra return values, in which
case if a file descriptor would be produced vn_open fails with
EOPNOTSUPP.

Since I'm rearranging vn_open's signature anyway, stop exposing struct
nameidata. Instead, take three arguments: an optional vnode to use as
the starting point (like openat()), the path, and additional namei
flags to use, restricted to NOCHROOT and TRYEMULROOT. (Other namei
behavior, e.g. NOFOLLOW, can be requested via the open flags.)

This change requires a kernel bump. Ride the one an hour ago.
(That was supposed to be coordinated; did not intend to let an hour
slip by. My fault.)

Rather than keeping a separate mutex, condvar, and pserialize for each
module hook, we can share a common set of synchronization structures.
This cuts the amount of cacheline_aligned data for these structures by
50%.

Note that we still have a per-hook localcount, since we need to count
individual references.

Add void * function pointer casts. There are different ways to "fix" those
warnings:
    1. this one: add a void * cast (which I think is the least intrusive)
    2. add pragmas to elide the warning
    3. add intermediate inline conversion functions
    4. change the called function prototypes, adding unused arguments and
       converting some of the pointer arguments to void *.
    5. make the functions varyadic (which defeats the purpose of checking)
    6. pass command line flags to elide the warning
I did try 3 and 4 and I was not pleased with the result (sys_ptrace_common.c)
(3) added too much code and defines, and (4) made the regular use clumsy.

Fix a read-beyond-end string read.

coredump_buildname() copies 'pattern' into 'name', and handles special
characters such as "%n". "%n", if present, will be replaced by p->p_comm.

	error = coredump_buildname(p, name, pattern, MAXPATHLEN);

This function handles overflows, and returns an error when 'name' becomes
larger than MAXPATHLEN. However, when coredump() calls it, 'name' is used
before the error check, with:

	lastslash = strrchr(name, '/');

'name' is not guaranteed to be NUL-terminated, because of the *d = *s in
coredump_buildname(). This strrchr will read a string which is not NUL-
terminated (ie. until finding a '\0' in memory).

'pattern' can't be higher than MAXPATHLEN. A user can fill it in via a
PT_DUMPCORE ptrace call, given the input is not longer than MAXPATHLEN.
Since the 2-bytes-sized "%n"s will be replaced by p->p_comm (which is
user-settable, like a 10-bytes-sized "0123456789"), 'name' can become
longer than 'pattern' (and thus longer than MAXPATHLEN). Some 'a's at the
end of the buffer will make sure 'name' is not NUL-terminated.

    pattern: "%n%n%naaaaaaaaaaaaaaaaaaaaaaaaaaaa\0"
              | | | |||||||||||||||||||||||||||||
  ->   name: "012345678901234567890123456789aaaaa" [no \0]
              |         |         |         |||||MAXPATHLEN

Fix it by checking 'error' before calling strrchr.

Instead of generating all the 'note' sections twice (and hoping that the
  'fast path' size on the first path matches the actual size on the second)
  save all the notes (mostly the cpu registers for all the LWPs) in
  malloced memory on the first pass.
Sanity check that the number of memory segments matches written matches
  the count obtained earlier. If gcore() is used they could differ.
  (Not sure that returning ENOMEM is ideal, but it is better than a crash.)

Change the type of the 'cookie' that holds the state of the core dump file
from 'void *' to the actual type 'struct coredump_iostate *'.
In most of the code the contents of the structure are still unknown.
This just stops the wrong type of pointer being passed to the 'void *'
parameter.
I hope I've found everything, amd64 GENERIC and i386 GENERIC & ALL compile.

Don't dump core on an existing core file we don't own. From OpenBSD, suggested
by Greg Woods.

Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.

Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).

The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

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.

Remove the "struct lwp *" argument from all VFS and VOP interfaces.
The general trend is to remove it from all kernel interfaces and
this is a start.  In case the calling lwp is desired, curlwp should
be used.
