ce1b857f33 Validate the page in one place, dev_pager_getpages(), rather than doing it
in two places, dev_pager_getfake() and dev_pager_updatefake().

Compare a pointer to "NULL" rather than "0".

3952a5abc9 Updates after r194640:
- shrink size guards for vnet_net.
  vnet_rtable does not need size guards as it is self-contained.
- remove a bunch of defines from vnet.h no longer valid.

b58ea5f310 Move virtualization of routing related variables into their own
Vimage module, which had been there already but now is stateful.

All variables are now file local; so this further limits the global
spreading of routing related things throughout the kernel.

Add a missing function local variable in case of MPATHing.

571e8e20da Change cam_periph_ioctl() to take 'cmd' and a u_long instead of an
int.  All of its callers pass in cmd as a u_long, so this has

8896f83a58 Add a new function, ifa_ifwithaddr_check(), which rather than returning
a pointer to an ifaddr matching the passed socket address, returns a
boolean indicating whether one was present.  In the (near) future,
ifa_ifwithaddr() will return a referenced ifaddr rather than a raw
ifaddr pointer, and the new wrapper will allow callers that care only
about the boolean condition to avoid having to free that reference.

cc18b1dbf0 Add a global rwlock, at_ifaddr_rw, to protect the global netatalk
address lists, at_ifaddr_list.  Acquire the lock, and use ifaddr
refcounts where necessary, to close most known address-related
races in netatalk.

Annotate one potential race in at_control() where we acquire an
ifaddr reference, drop the global lock, and scrub the address from
the ifnet before re-acquiring the global lock, which could allow
for a writer-writer race.

5bf423734c Add ipx_ifaddr locking to ipx_control(), which should close most
remaining potential races in ifconfig's management of IPX addresses.

This is largely accomplished by dropping a global write lock for the
IPX address list over the body of in_control(), although there are
some places we bump the refcount on an ifaddr of interest while
calling out to the routing code or link layer code, which might
require revisiting.

Annotate one as a potential race if two simultaneous delete ioctls
are issued for the same IPX addresses at once.

1099f828b3 Clean up common ifaddr management:
- Unify reference count and lock initialization in a single function,
  ifa_init().
- Move tear-down from a macro (IFAFREE) to a function ifa_free().
- Move reference count bump from a macro (IFAREF) to a function ifa_ref().
- Instead of using a u_int protected by a mutex to refcount(9) for
  reference count management.

The ifa_mtx is now used for exactly one ioctl, and possibly should be
removed.

e0c161b89c Add another flags argument to vn_open_cred. Use it to specify that some
vn_open_cred invocations shall not audit namei path.

In particular, specify VN_OPEN_NOAUDIT for dotdot lookup performed by
default implementation of vop_vptocnp, and for the open done for core
file. vn_fullpath is called from the audit code, and vn_open there need
to disable audit to avoid infinite recursion. Core file is created on
return to user mode, that, in particular, happens during syscall return.
The creation of the core file is audited by direct calls, and we do not
want to overwrite audit information for syscall.

941c2e1cd1 Remove historical support for capturing IPX packets in the output path
using raw IPX sockets.  While functional, this support is disabled
using a flag that can't be changed from userspace, and google reveals
no documentation or use of that flag anywhere.  This eliminates a
potential lock order reversal and code reentrance issue in which the
output path reentered the input path in IPX.

An alternative to removal would be to use the netisr, as a comment I
added in 2005 suggests.  While this change is fairly straight-forward,
the lack of any consumers or the easy possibility of consumers (kernel
modification and recompile required) suggests that this is simply an
unused feature.

Update README to remove this TODO, and a TODO regarding IPX/IP
encapsulation which was also removed a few years ago.

b96ad4b205 For ICH based fxp(4) controllers treat them as 82559 compatibles.
To detect which controller is ICH based one, add a new member
variable ich to struct fxp_ident and move the struct to
if_fxpvar.h. Since I've faked controller revision, don't allow
microcode loading for ICH based controllers.

6b24912cd9 Overhaul fxp(4) multicast filter programming. fxp(4) hardwares do
not allow multicast filter programming when controller is busy to
send/receive frames. So it used to mark need_mcsetup bit and defer
multicast filter programming until controller becomes idle state.
To detect when the controller is idle fxp(4) relied on Tx
completion interrupt with NOP command and fxp_start_body and
fxp_intr_body had to see whether pending multicast filter
programming was requested. This resulted in very complex logic and
sometimes it did not work as expected.
Since the controller should be in idle state before any multicast
filter modifications I changed it to reinitialize the controller
whenever multicast filter programming is required. This is the same
way what OpenBSD and NetBSD does. Also I added IFF_DRV_RUNNING
check in ioctl handler so controller would be reinitialized only if
it is absolutely needed.
With this change I guess we can remove fxp(4) DELAY hack in ifioctl
for IPv6 case.

invoke fxp_intr_body if fxp(4) is not running. With this change
