r186052 from head to stable/7; note that only the locking fixes and
invariants checking are added from r185747, but not the move to an
rwlock which would modify the kernel binary interface, nor the move
to a non-recursible lock, which is still seeing problem reports in
head. This corrects, among other things, a deadlock that may occur
when processing incoming ICMP redirects.
r185747:
- convert radix node head lock from mutex to rwlock
- make radix node head lock not recursive
- fix LOR in rtexpunge
- fix LOR in rtredirect
Reviewed by: sam
r185774:
- avoid recursively locking the radix node head lock
- assert that it is held if RTF_RNH_LOCKED is not passed
r185807:
Fix a bug introduced in r185747: rather than dereferencing an
uninitialized *rt to something undefined, use the fibnum that came in
as function argument.
Found with: Coverity Prevent(tm)
CID: 4168
r185849:
fix a reported panic when adding a route and one hit here when deleting
a route
- pass RTF_RNH_LOCKED to rtalloc1_fib in 2 cases where the lock is held
- make sure the rnh lock is held across rt_setgate and rt_getifa_fib
r185964:
Pass RTF_RNH_LOCKED to rtalloc1 sunce the node head is locked, this
avoids a recursive lock panic on inet6 detach.

apologies to thompsa
r186051:
in6_addroute is called through rnh_addadr which is always called with
the radix node head lock held exclusively. Pass RTF_RNH_LOCKED to
rtalloc so that rtalloc1_fib will not try to re-acquire the lock.
r186052:
don't acquire lock recursively
Oiginal commits to head were by kmacy, except r185964 by thompsa and
r185807 by bz.
A subset of this is a potential errata patch candidate.

Correct a deadlock and a rtentry leak in rt_check():
- In the event that a gateway route has to be looked up, drop the lock
on 'rt' before reacquiring it 'rt0' in order to avoid deadlock.
- In the event the original route has evaporated or is no longer up
after the gateway route lookup, call RTFREE() on the gateway route
before retrying.
This is a potential errata candidate patch.

Merge r184508 from head to stable/7:
Historically, /dev/auditpipe has allows only whole records to be read via
read(2), which meant that records longer than the buffer passed to read(2)
were dropped. Instead take the approach of allowing partial reads to be
continued across multiple system calls more in the style of streaming
character device.
This means retaining a record on the per-pipe queue in a partially read
state, so maintain a current offset into the record. Keep the record on
the queue during a read, so add a new lock, ap_sx, to serialize removal
of records from the queue by either read(2) or ioctl(2) requesting a pipe
flush. Modify the kqueue handler to return bytes left in the current
record rather than simply the size of the current record.
It is now possible to use praudit, which used the standard FILE * buffer
sizes, to track much larger record sizes from /dev/auditpipe, such as
very long command lines to execve(2).

Merge r184536 from head to stable/7:
We only allow a partial read of the first record in an audit pipe
record queue, so move the offset field from the per-record
audit_pipe_entry structure to the audit_pipe structure.
Now that we support reading more than one record at a time, add a
new summary field to audit_pipe, ap_qbyteslen, which tracks the
total number of bytes present in a pipe, and return that (minus
the current offset) via FIONREAD and kqueue's data variable for
the pending byte count rather than the number of bytes remaining
in only the first record.
Add a number of asserts to confirm that these counts and offsets
following the expected rules.

Merge r188485 from head to stable/7:
Modify fdcopy() so that, during fork(2), it won't copy file descriptors
from the parent to the child process if they have an operation vector
of &badfileops. This narrows a set of races involving system calls that
allocate a new file descriptor, potentially block for some extended
period, and then return the file descriptor, when invoked by a threaded
program that concurrently invokes fork(2). Similar approches are used
in both Solaris and Linux, and the wideness of this race was introduced
in FreeBSD when we moved to a more optimistic implementation of
accept(2) in order to simplify locking.
A small race necessarily remains because the fork(2) might occur after
the finit() in accept(2) but before the system call has returned, but
that appears unavoidable using current APIs. However, this race is
vastly narrower.
The fix can be validated using the newfileops_on_fork regression test.

Add SIM refcounting. This is slightly different from what DragonFly
does - in DragonFly, it's cam_sim_release() what actually frees the
SIM; cam_sim_free does nothing more than calling cam_sim_release().
Here, we drain in cam_sim_free, waiting for refcount to drop to zero.
We cannot do the same think DragonFly does, because after cam_sim_free
returns, client would destroy the sim->mtx, and CAM would trip over
an initialized mutex.

Original commit log:
A partial solution to some of the 'pull the umass device with a
mounted FS' problems. These are more along the lines of 'avoiding an
avoidable panic' than a complete solution to removable devices. We
now close the barn door after the horse has gotten lose and has been
hit by a truck, as it were. The barn no longer catches fire in this
case, but the horse is still dead :-).
The vfs_bio.c fix causes us not to put a failed write back into the
dirty pool if the error returned was ENXIO. In that case, the buffer
is treated like any other clean buffer that's being retured. ENXIO
means the device isn't there anymore and will never be there again in
the future, so retrying is futile.
The vfs_mount.c fix treats 'ENXIO' as success for unmounting a file
system. If the device is gone, retrying later won't help and we'll
never be able to unmount the device.
These two are part of a larger patch set submitted by the author. The
other patches will be forth coming. I added comments to these two
patches.

According to phk@, VOP_STRATEGY should never, _ever_, return
anything other than 0. Make it so. This fixes
"panic: VOP_STRATEGY failed bp=0xc320dd90 vp=0xc3b9f648",
encountered when writing to an orphaned filesystem. Reason
for the panic was the following assert:
KASSERT(i == 0, ("VOP_STRATEGY failed bp=%p vp=%p", bp, bp->b_vp));
at vfs_bio:bufstrategy().

MFC r188240:
When a device containing mounted UFS filesystem disappears, the type
of devvp becomes VBAD, which UFS incorrectly interprets as snapshot
vnode, which in turns causes panic. Fix it by replacing '!= VCHR'
with '== VREG'.
With this fix in place, you should no longer be able to panic the system
by removing a device with an UFS filesystem mounted from it - assuming
you don't use softupdates.

Merge r187686 from head to stable/7:
When a statically linked binary is executed (or at least, one without
an interpreter definition in its program header), set the auxiliary
ELF argument AT_BASE to 0 rather than to the address that we would
have mapped the interpreter at if there had been one.
The ELF ABI specifications appear to be ambiguous as to the desired
behavior in this situation, as they define AT_BASE as the base address
of the interpreter, but do not mention what to do if there is none.
On Solaris, AT_BASE will be set to the base address of the static
binary if there is no interpreter, and on Linux, AT_BASE is set to 0.
We go with the Linux semantics as they are of more immediate utility
and allow the early runtime environment to know that the kernel has
not mapped an interpreter, but because AT_PHDR points at the ELF
header for the running binary, it is still possible to retrieve all
required mapping information when the process starts should it be
required. Either approach would be preferable to our current behavior
of passing a pointer to an unmapped region of user memory as AT_BASE.

Merge a couple of changes from HEAD, plus fix a potential warning.
In detail:
+ we used SYSCTL_LONG to show a 64-bit variable. For the time being
just remove the variable from the list of sysctl-exported values.
Unfortunately our SYSCTL macros do not do proper type checking
of the arguments so we might have some more bugs of this kind
across the codebase;
+ fw_debug has not been used for ages, so remove it;
+ gcc 4.2.4 tells me that src_ip.s_addr may be not initialized,
so make sure it is.
I need to check what is the status of this field in head.
