136446540a When aio_read/write() is used on a raw device, physical buffers are
used for up to "vfs.aio.max_buf_aio" of the requests.  If a request
size is MAXPHYS, but the request base isn't page aligned, vmapbuf()
will map the end of the user space buffer into the start of the kva
allocated for the next physical buffer.  Don't use a physical buffer
in this case.  (This change addresses problem report 25617.)

When an aio_read/write() on a raw device has completed, timeout() is
used to schedule a signal to the process.  Thus, the reporting is
delayed up to 10 ms (assuming hz is 100).  The process might have
terminated in the meantime, causing a trap 12 when attempting to
deliver the signal.  Thus, the timeout must be cancelled when removing
the job.

aio jobs in state JOBST_JOBQGLOBAL should be removed from the
kaio_jobqueue list during process rundown.

During process rundown, some aio jobs might move from one list to a
different list that has already been "emptied", causing the rundown to
be incomplete.  Retry the rundown.

A call to BUF_KERNPROC() is needed after obtaining a physical buffer
to disassociate the lock from the running process since it can return
to userland without releasing that lock.

5951069a87 netgraph.h:
Change a prototype.
  Add a function version of ng_ref_node() when debugging so
  a breakpoint can be set on it.
ng_base.c:
  add 'node' as an argument to ng_apply_item so that it is up
  to the caller to take over and release the item's reference on
  the node. If the release reports back that the node went away
  due to the reference going to 0, the caller should cease referencing
  the now defunct node. (e.g. the item was a 'kill node' message).
  Alter ng_unref_node to report back the residual references as a result.
ng_pptpgre.c:
  Don't reference a node after we dropped a reference to it.
  (What if it was the last?)
Fixes a node leak reported by Harti Brandt <brandt@fokus.gmd.de>
 which was due to an incorrect earlier attempt to fix the
 "accessing node after dropping the last reference" problem.

02c986ab54 Very large makeover of the /dev/random driver.
o Separate the kernel stuff from the Yarrow algorithm. Yarrow is now
  well contained in one source file and one header.

o Replace the Blowfish-based crypto routines with Rijndael-based ones.
  (Rijndael is the new AES algorithm). The huge improvement in
  Rijndael's key-agility over Blowfish means that this is an
  extremely dramatic improvement in speed, and makes a heck of
  a difference in its (lack of) CPU load.

o Clean up the sysctl's. At BDE's prompting, I have gone back to
  static sysctls.

o Bug fixes. The streamlining of the crypto stuff enabled me to
  find and fix some bugs. DES also found a bug in the reseed routine
  which is fixed.

o Change the way reseeds clear "used" entropy. Previously, only the
  source(s) that caused a reseed were cleared. Now all sources in the
  relevant pool(s) are cleared.

o Code tidy-up. Mostly to make it (nearly) 80-column compliant.

de328d4a59 Avoid complicated tests of whether devices are present or not, and
enable all harvesting options by default since having them on for
devices not present doesn't hurt anything. Leave them on by default
since for the most part they are not producing noticable slowdown,
and are about to get a lot more efficient.

its complete removal.

d30344bdfa When creating a shadow vm_object in vmspace_fork(), only one
reference count was transferred to the new object, but both the
new and the old map entries had pointers to the new object.
Correct this by transferring the second reference.

This fixes a panic that can occur when mmap(2) is used with the
MAP_INHERIT flag.
