then the mbuf has been consumed by a hook; otherwise beware of a null
mbuf return (gack). In particular the bridge was doing the wrong thing.
While in the ipv6 code make it's handling of pfil_run_hooks identical
to netbsd.

change 38496
o add ipsec_osdep.h that holds os-specific definitions for portability
o s/KASSERT/IPSEC_ASSERT/ for portability
o s/SPLASSERT/IPSEC_SPLASSERT/ for portability
o remove function names from ASSERT strings since line#+file pinpints
the location
o use __func__ uniformly to reduce string storage
o convert some random #ifdef DIAGNOSTIC code to assertions
o remove some debuggging assertions no longer needed
change 38498
o replace numerous bogus panic's with equally bogus assertions
that at least go away on a production system
change 38502 + 38530
o change explicit mtx operations to #defines to simplify
future changes to a different lock type
change 38531
o hookup ipv4 ctlinput paths to a noop routine; we should be
handling path mtu changes at least
o correct potential null pointer deref in ipsec4_common_input_cb
chnage 38685
o fix locking for bundled SA's and for when key exchange is required
change 38770
o eliminate recursion on the SAHTREE lock
change 38804
o cleanup some types: long -> time_t
o remove refrence to dead #define
change 38805
o correct some types: long -> time_t
o add scan generation # to secpolicy to deal with locking issues
change 38806
o use LIST_FOREACH_SAFE instead of handrolled code
o change key_flush_spd to drop the sptree lock before purging
an entry to avoid lock recursion and to avoid holding the lock
over a long-running operation
o misc cleanups of tangled and twisty code
There is still much to do here but for now things look to be
working again.

be somewhat unreliable, although not too unreliable for shared

make sure we return any allocated space to the drive. This should get
rid of a number of inconsistencies (hopefully all) that have been seen
after configuration errors.
even could call VOP_REVOKE() on vnodes associated with its dev_t's

If there are things people belive destroy_dev() needs to learn how to
do, please tell me about it, preferably with a reproducible test case.
Include <sys/uio.h> in bluetooth code rather than rely on <sys/vnode.h>
to do so.
The fact that some of the USB code needs to include <sys/vnode.h>
still disturbs me greatly, but I do not have time to chase that.
from fiddling with CS_TTGO since fiddling with CS_TTGO was removed in
rev.1.218 of the i386/isa version (which was merged with loss of history
in rev.1.223 of this version).
some symbols in X_db_search_symbol(). Reject the same symbols that
rev.1.13 did (all except STT_OBJECT and STT_FUNC), except don't reject
typeless symbols. This keeps the typeless symbols in non-verbosely
written assembler code visible, but makes file symbols invisible. ELF
file symbols have type STT_FILE and value 0, so this stops small values
and offsets sometimes being displayed in terms of the first file symbol
in the kernel (usually device_if.c). I think it rejects some other
unwanted symbols (small absolute symbols for things like struct offsets).
It may reject some wanted symbols (large absolute symbols for addresses
like PTmap).
about because we're still tier 2 and our current compiler, as well
as future compilers will not support varargs. This is mostly a
no-op in practice, because <sys/varargs.h> should already cause
compile failures.
use the ability on ia64 to map the register stack. The orientation of
the stack (i.e. its grow direction) is passed to vm_map_stack() in the
overloaded cow argument. Since the grow direction is represented by
bits, it is possible and allowed to create bi-directional stacks.
This is not an advertised feature, more of a side-effect.
Fix a bug in vm_map_growstack() that's specific to rstacks and which
we could only find by having the ability to create rstacks: when
the mapped stack ends at the faulting address, we have not actually
mapped the faulting address. we need to include or cover the faulting
address.
Note that at this time mmap(2) has not been extended to allow the
creation of rstacks by processes. If such a need arises, this can
be done.
Tested on: alpha, i386, ia64, sparc64
do exactly the same as vop_nopoll() for consistency and put a
comment in the two pointing at each other.
Retire seltrue() in favour of no_poll().
Create private default functions in kern_conf.c instead of public
ones.
Change default strategy to return the bio with ENODEV instead of
doing nothing which would lead the bio stranded.
Retire public nullopen() and nullclose() as well as the entire band
of public no{read,write,ioctl,mmap,kqfilter,strategy,poll,dump}
funtions, they are the default actions now.
Move the final two trivial functions from subr_xxx.c to kern_conf.c
and retire the now empty subr_xxx.c
This is just a cleanup here (modulo rev.1.108 of kern/tty.c), since the
input speed can be different from to output speed and extra code to
handle both speeds naturally handled all cases.
provide no methods does not make any sense, and is not used by any
driver.
It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.
Change the defaults to be nullopen() and nullclose() which simply
does nothing.
Remove explicit initializations to these from the drivers which
already used them.
- Removed conversion of a zero input speed to the output speed. This
has been done better in ttioctl() since rev.1.108 of kern/tty.c
almost 5 years ago. comparam() did the conversion incompletely for
the case where the output speed is also zero. It had complications
to avoid using zero speeds, but would still have used a zero input
speed for setting watermarks if kern/tty.c had passed one.
- Never permit the input speed to be different from the output speed.
There was no validity check on the input speed for the case of a zero
output speed. Then we didn't change the physical speeds, but we used
the unvalidated input speed for setting watermarks and didn't return
an error, so ttioctl() stored the unvalidated input speed in the tty
struct where it could cause problems later.
- Removed complications that were to avoid using a divisor of 0. The
divisor is now always valid if the speed is accepted.
cd_setreg() were still using !(read_eflags() & PSL_I) as the condition
for the lock hidden by COM_LOCK() (if any) being held. This worked
when spin mutexes and/or critical_enter() used hard interrupt disablement,
but it has caused recursion on the non-recursive mutex com_mtx since
all relevant interrupt disablement became soft. The recursion is
harmless unless there are other bugs, but it breaks an invariant so
it is fatal if spinlocks are witnessed.
