1af04fadd1 Take a shot at fixing a nasty bug in the pmap changes that I did. I
missed the pmap_kenter/kremove in this file, which leads to read()/write()
of /dev/mem using stale TLB entries. (gah!)  Fortunately, mmap of /dev/mem
wasn't affected, so it wasn't as bad as it could have been.  This throws
some light on the 'X server affects stability' thread....

073eef8ca2 Add code that will download firmware to a Symbol LA4100-series of CF
cards.  Since the firmware is hard coded into the kernel, I've made it
a kernel option (WI_SYMBOL_FIRMWARE).

Note: This only downloads into the RAM of these cards.  It doesn't
download into FLASH, and is somewhat limited.  There needs to be a
better way to deal, but this works for now.  My Symbol LA4132 CF card
works now.

f2b17113cf Make the consumers of the linker_load_file() function use
linker_load_module() instead.

This fixes a bug where the kernel was unable to properly locate and
load a kernel module in vfs_mount() (and probably in the netgraph
code as well since it was using the same function).  This is because
the linker_load_file() does not properly search the module path.

ebbd4fa8c8 Introduce support for Mandatory Access Control and extensible
kernel access control.

Hook up various policy modules to the kernel build.

Note that a number of these modules require futher entry point commits
in the remainder of the kernel to become fully functional, but enough
of the pieces are in place to allow experimentation.

Note also that it would be desirable to not build the mac_*.ko modules
if 'options MAC' is not defined in the kernel configuration, because
the resulting modules are not useful without the kernel option.  There
doesn't appear to be precedent for a way to do this -- for example,
we allow ipfw.ko to be built even if 'options NETINET' isn't defined.
Suggests welcomed on the "best" way to do this.

4a58340e98 Introduce support for Mandatory Access Control and extensible
kernel access control

Invoke appropriate MAC framework entry points to authorize a number
of vnode operations, including read, write, stat, poll.  This permits
MAC policies to revoke access to files following label changes,
and to limit information spread about the file to user processes.

Note: currently the file cached credential is used for some of
these authorization check.  We will need to expand some of the
MAC entry point APIs to permit multiple creds to be passed to
the access control check to allow diverse policy behavior.

Restructure the vn_open_cred() access control checks to invoke

here is the same as other failure modes following creation,
wherein an empty file may be left behind.

other references to that vnode as a trace vnode in other processes as well
as in any pending requests on the todo list.  Thus, it is possible for a

239b5b9707 o Setting PG_MAPPED and PG_WRITEABLE on pages that are mapped and unmapped
by pmap_qenter() and pmap_qremove() is pointless.  In fact, it probably
   leads to unnecessary pmap_page_protect() calls if one of these pages is
   paged out after unwiring.

Note: setting PG_MAPPED asserts that the page's pv list may be
non-empty.  Since checking the status of the page's pv list isn't any
harder than checking this flag, the flag should probably be eliminated.
Alternatively, PG_MAPPED could be set by pmap_enter() exclusively
rather than various places throughout the kernel.

d8a7b7a3cd Introduce support for Mandatory Access Control and extensible
kernel access control.

Provide implementations of some sample operating system security
policy extensions.  These are not yet hooked up to the build as
other infrastructure is still being committed.  Most of these
work fairly well and are in daily use in our development and (limited)
production environments.  Some are not yet in their final form,
and a number of the labeled policies waste a lot of kernel memory
and will be fixed over the next month or so to be more conservative.
They do give good examples of the flexibility of the MAC framework
for implementing a variety of security policies.

mac_biba:	Implementation of fixed-label Biba integrity policy,
		similar to those found in a number of commercial
		trusted operating systems.  All subjects and objects
		are assigned integrity levels, and information flow
		is controlled based on a read-up, write-down
		policy.  Currently, purely hierarchal.

mac_bsdextended:	Implementation of a "file system firewall",
		which allows the administrator to specify a series
		of rules limiting access by users and groups to
		objects owned by other users and groups.  This
		policy is unlabeled, relying on existing system
		security labeling (file permissions/ownership,
		process credentials).

mac_ifoff:	Secure interface silencing.  Special-purpose module
		to limit inappropriate out-going network traffic
		for silent monitoring scenarios.  Prevents the
		various network stacks from generating any output
		despite an interface being live for reception.

mac_mls:	Implementation of fixed-label Multi-Level Security
		confidentiality policy, similar to those found in
		a number of commercial trusted operating systems.
		All subjects and objects are assigned confidentiality
		levels, and information flow is controlled based on
		a write-up, read-down policy.  Currently, purely
		hiearchal, although non-hierarchal support is in the
		works.

mac_none:	Policy module implementing all MAC policy entry
		points with empty stubs.  A good place to start if
		you want all the prototypes types in for you, and
		don't mind a bit of pruning.  Can be loaded, but
		has no access control impact.  Useful also for
		performance measurements.

mac_seeotheruids:	Policy module implementing a security service
		similar to security.bsd.seeotheruids, only a slightly
		more detailed policy involving exceptions for members
		of specific groups, etc.  This policy is unlabeled,
		relying on existing system security labeling
		(process credentials).

mac_test:	Policy module implementing basic sanity tests for
		label handling.  Attempts to ensure that labels are
		not freed multiple times, etc, etc.

at the granularity of the socket.  Two labels are stored for each
socket: the label of the socket itself, and a cached peer label
permitting interogation of the remote endpoint.  Since socket locking
is not yet present in the base tree, these objects are not locked,
but are assumed to follow the same semantics as other modifiable
entries in the socket structure.

Label process credentials, permitting security information to be
maintained at the granularity of processes and cached credential
objects.  cr_label follows the semantics of other entries in struct
ucred: when a credential is exclusively referenced, it may be
modified.  Otherwise, it must be treated as immutable.  As with
other interesting entries in struct ucred, failing to use the
documented credential management APIs (such as crcopy, crdup, ...)
can result in data corruption or incorrect behavior.

initial kernel implementation, although the interface with the userland
components of the oeprating system is still under work, and not all

documentation of which kernel subsystems will not work correctly with
a kernel compiled with MAC support will be added.

Label file system mount points, permitting security information to be
maintained at the granularity of the file system.  Two labels are
currently maintained: a security label for the mount itself, and
a default label for objects in the file system (in particular, for
file systems not supporting per-vnode labeling directly).

Introduce two node vnode operations required to support MAC.  First,
VOP_REFRESHLABEL(), which will be invoked by callers requiring that
vp->v_label be sufficiently "fresh" for access control purposes.
Second, VOP_SETLABEL(), which be invoked by callers requiring that
the passed label contents be updated.  The file system is responsible
for updating v_label if appropriate in coordination with the MAC
framework, as well as committing to disk.  File systems that are
not MAC-aware need not implement these VOPs, as the MAC framework
will default to maintaining a single label for all vnodes based
on the label on the file system mount point.

protected by the vnode lock and may be read only when holding a shared
lock, or modified only when holding an exclusive lock.  Label
information may be considered either the primary copy, or a cached
copy.  Individual file systems or kernel services may use the
VCACHEDLABEL flag for accounting purposes to determine which it is.
New VOPs will be introduced to refresh this label on demand, or to

c89137ff90 Make reference counting for mbuf clusters [only] work like in RELENG_4.
While I don't think this is the best solution, it certainly is the
fastest and in trying to find bottlenecks in network related code
I want this out of the way, so that I don't have to think about it.
What this means, for mbuf clusters anyway is:
- one less malloc() to do for every cluster allocation (replaced with
  a relatively quick calculation + assignment)
- no more free() in the cluster free case (replaced with empty space) :-)

This can offer a substantial throughput improvement, but it may not for
all cases.  Particularly noticable for larger buffer sends/recvs.

9e74cba35a Make a temporary copy of the output data in the generic sysctl handlers
so that the data is less likely to be inconsistent if SYSCTL_OUT() blocks.
If the data is large, wire the output buffer instead.

This is somewhat less than optimal, since the handler could skip the copy
if it knew that the data was static.

If the data is dynamic, we are still not guaranteed to get a consistent
copy since another processor could change the data while the copy is in
progress because the data is not locked.  This problem could be solved if
the generic handlers had the ability to grab the proper lock before the
copy and release it afterwards.

This may duplicate work done in other sysctl handlers in the kernel which
also copy the data, possibly while a lock is held, before calling they call
a generic handler to output the data.  These handlers should probably call
SYSCTL_OUT() directly.

7a415ec906 Revert the previous delta; uintfptr_t needs to be available to
userland for libc/gmon to compile, so the typedef in <machine/types.h>
isn't good enough.  This is really ugly since we end up with the
actual value which uintfptr_t is typedef'd from, in multiple places.
This is bug for bug compatible with the other FreeBSD architectures.

af13e3abb9 Unimplement panic(8) by making sure that we don't recurse into a
ruleset.  If we do, that means there's a ruleset loop (10 includes 20
include 30 includes 10), which will quickly cause a double fault due
to stack overflow (since "include" is implemented by recursion).
(Previously, we only checked that X didn't include X.)

30bbe52432 Implement a direct mapped address region, like alpha and ia64. This
basically maps all of physical memory 1:1 to a range of virtual addresses
outside of normal kva.  The advantage of doing this instead of accessing
phsyical addresses directly is that memory accesses will go through the
data cache, and will participate in the normal cache coherency algorithm
for invalidating lines in our own and in other cpus' data caches.  So
we don't have to flush the cache manually or send IPIs to do so on other
cpus.  Also, since the mappings never change, we don't have to flush them
from the tlb manually.
This makes pmap_copy_page and pmap_zero_page MP safe, allowing the idle
zero proc to run outside of giant.

implementation.  This flag will indicate that the security label
in the vnode is currently valid, and therefore doesn't need to
be refreshed before an access control decision can be made.  Most
file systems (or stdvops) will set this flag after they load the
MAC label from disk the first time to prevent redundant disk I/O;
some file synthetic file systems (procfs, for example) may not.

now, we can only do this easily for at most across one mbuf + one
cluster free, as the comment mentions (it also explains why).  Anyway,

dd4ac026f7 Introduce mb_free() to the MBP_PERSIST{,ENT} interface. What this means
is that grouped frees will be done as most often as possible without
dropping the cache lock in between.  So, for the most part, they'll be
done without the lock being dropped.  This is particularly true if you
have something that does a grouped m_getm() or m_getcl() (a cluster and
mbuf at the same time) - most likely getting the buffers from the
same per-CPU cache - and then frees them with m_free{,m}().  Unless
the buffers' underlying buckets were moved, the free will be done without
the lock getting dropped in between.  So far, only m_free() has been
shown how to do this, and m_freem() will shortly follow.

Since I'm here, I also fixed a small (but mostly harmless) type-mismatch
introduced in the last commit.
