e74334caae Move MEM_USR a page upwards to make space for larger UFS1 boot2.
Load 4 sectors more than we used to.  This is harmless overhead for
the UFS1_ONLY case, but sufficient for boot2(UFS1+2).

d71dec96bf Minor string handling cleanup that I've had in my tree for a while:
Don't use snprintf where strlcpy() will do the job.
Also, a NUL is '\0' not 0 in our style (C doesn't care), so spell it like.

adfa3213c7 Copyin and copyout are only possible from a process-native thread,
and therefore we need a way for ioctl handlers to run in that thread
in GEOM.  Rather than invent a complicated registration system to
recognize which ioctl handler to use for a given ioctl, we still
schedule all ioctls down the tree as bio transactions but add a
special return code that means "call me directly" and have the
geom_dev layer do that.

Use this for all ioctls that make it as far as a diskdriver to
avoid any backwards compatibility problems.

3097aa70be Dynamically configure the width of the srom. This code comes from
OpenBSD who got the code (or the idea) from the NetBSD tlp driver.

This gets some cardbus dc cards working (either completely or nearly
so).  It also appears to get additional pci cards working, without
breaking working ones.

# Maybe some additional work is needed here.  Also, the cardbus attachment
# might need to match on the CIS rather than on the vendor/device so we have
# a finer level of detail as to what the card is.  Technically, the
# vendor/device fields are undefined for CardBus (even though most cards are
# using common silicon with pci models).

e183f80e54 Sync from MAC tree: break out the single mmap entry point into
seperate entry points for each occasion:

mac_check_vnode_mmap()		Check at initial mapping
mac_check_vnode_mprotect()	Check at mapping protection change
mac_check_vnode_mmap_downgrade()	Determine if a mapping downgrade
					should take place following
					subject relabel.

Implement mmap() and mprotect() entry points for labeled vnode
policies.  These entry points are currently not hooked up to the
VM system in the base tree.  These changes improve the consistency
of the access control interface and offer more flexibility regarding
limiting access to vnode mmaping.

this requires policy modules to accept the case where the label

3bd6561289 NB: This commit does *NOT* make GEOM the default in FreeBSD
NB: But it will enable it in all kernels not having options "NO_GEOM"

Put the GEOM related options into the intended order.

Add "options NO_GEOM" to all kernel configs apart from NOTES.

In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.

There are currently three known issues which may force people to
need the NO_GEOM option:

boot0cfg/fdisk:
        Tries to update the MBR while it is being used to control
        slices.  GEOM does not allow this as a direct operation.

SCSI floppy drives:
        Appearantly the scsi-da driver return "EBUSY" if no media
        is inserted.  This is wrong, it should return ENXIO.

PC98:
        It is unclear if GEOM correctly recognizes all variants of
        PC98 disklabels.  (Help Wanted!  I have neither docs nor HW)

These issues are all being worked.

96adb90996 Begin another merge from the TrustedBSD MAC branch:
- Change mpo_init_foo(obj, label) and mpo_destroy_foo(obj, label) policy
  entry points to mpo_init_foo_label(label) and
  mpo_destroy_foo_label(label).  This will permit the use of the same
  entry points for holding temporary type-specific label during
  internalization and externalization, as well as for caching purposes.
- Because of this, break out mpo_{init,destroy}_socket() and
  mpo_{init,destroy}_mount() into seperate entry points for socket
  main/peer labels and mount main/fs labels.
- Since the prototype for label initialization is the same across almost
  all entry points, implement these entry points using common
  implementations for Biba, MLS, and Test, reducing the number of
  almost identical looking functions.

This simplifies policy implementation, as well as preparing us for the
merge of the new flexible userland API for managing labels on objects.

6d4d944e33 Get Vinum up and running with GEOM:
(1) Use namei() and devfs to discover devices rather than a hard-coded
    MAKEDEV implementation.  Once rootfs is in place, this will allow
    Vinum to be used for the root file system partition.

(2) Pass FREAD to device opens so that GEOM will return sector size
    rather than an error on attempts to read label data.

(3) Avoid clobbering return values from close_drive() and masking this
    failure, resulting in a later divide by zero due to not having
    updated the Vinum-cached sector size.

(4) Ignore failures from DIOCWLABEL as that appears not to be required
    in the GEOM environment.

We've done testing in simple Vinum environments, but those with more
complex environments might want to give this a spin in DP2 and make
sure everything is up to speed.

091d81d134 In-kernel crypto framework derived from openbsd. This facility provides
a consistent interface to h/w and s/w crypto algorithms for use by the
kernel and (for h/w at least) by user-mode apps.  Access for user-level
code is through a /dev/crypto device that'll eventually be used by openssl
to (potentially) accelerate many applications.  Coming soon is an IPsec
that makes use of this service to accelerate ESP, AH, and IPCOMP protocols.

Included here is the "core" crypto support, /dev/crypto driver, various
crypto algorithms that are not already present in the KAME crypto area,
and support routines used by crypto device drivers.

38e2693b94 Unhook the SCSI CD driver from the disk "mini-layer" and/or GEOM.
SCSI disks are too square pegs for the round holes in both of these.

And since atapi-cd has clearly shown that there are better acccess
models for CD media than trying to pretend to be a classical disk,
we stop the masquerade rather than patch up the costume.

But do implement the DIOCGMEDIASIZE and DIOCGSECTORSIZE so it will
be possible to manually attach to GEOM, should some the need arise.

Ideally, this driver should do media-detection and call make_dev()
when a CD is inserted and destroy_dev() when it is removed, this
would allow our future devd(8) to automount etc etc but coding that
takes SCSI-clue beyond anything I posses.

120e7b6b43 Do a bit of rude hackery to get clock interrupts on all CPUs. This
is partly based on the Alpha system which duplicates the clock to
each cpu, instead of doing a clock roundrobin like on i386.  This means
we get hz * ncpu clocks per second and so we have to seperate clock
sampling from actual 'do the work' clock processing.  The BSP runs the
complete processing, the rest just sample state etc.

Using the on-cpu interval timer is not ideal as it will drift.  There
is more to be done here, we should use an external clock source.

551cf4e150 Rename the mutex thread and process states to use a more generic 'LOCK'
name instead.  (e.g., SLOCK instead of SMTX, TD_ON_LOCK() instead of
TD_ON_MUTEX())  Eventually a turnstile abstraction will be added that
will be shared with mutexes and other types of locks.  SLOCK/TDI_LOCK will
be used internally by the turnstile code and will not be specific to
mutexes.  Making the change now ensures that turnstiles can be dropped
in at a later date without affecting the ABI of userland applications.

316ec49abd Some kernel threads try to do significant work, and the default KSTACK_PAGES
doesn't give them enough stack to do much before blowing away the pcb.
This adds MI and MD code to allow the allocation of an alternate kstack
who's size can be speficied when calling kthread_create.  Passing the
value 0 prevents the alternate kstack from being created.  Note that the
ia64 MD code is missing for now, and PowerPC was only partially written
due to the pmap.c being incomplete there.
Though this patch does not modify anything to make use of the alternate
kstack, acpi and usb are good candidates.

92dbb82a47 Add a new MAC entry point, mac_thread_userret(td), which permits policy
modules to perform MAC-related events when a thread returns to user
space.  This is required for policies that have floating process labels,
as it's not always possible to acquire the process lock at arbitrary
points in the stack during system call processing; process labels might
represent traditional authentication data, process history information,
or other data.

LOMAC will use this entry point to perform the process label update
prior to the thread returning to userspace, when plugged into the MAC
framework.

1d56414515 - Adjust comment noting that handling of CPU limit exhaustion is done in
ast().
- Actually set KEF_ASTPENDING so ast() is called.  I think this is buggy
  for a process with multiple KSE's in that PS_XCPU is not a KSE event,
  it's a process-wide event.  IMO there really should probably be two
  ASTPENDING flags, one for per-process, and one for per-KSE.

3bb24c35f2 Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:
Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.

These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.

This commit adds a number of such #includes.

1aa37f5392 Improve locking of pipe mutexes in the context of MAC:
(1) Where previously the pipe mutex was selectively grabbed during
    pipe_ioctl(), now always grab it and then release if if not
    needed.  This protects the call to mac_check_pipe_ioctl() to
    make sure the label remains consistent.  (Note: it looks
    like sigio locking may be incorrect for fgetown() since we
    call it not-by-reference and sigio locking assumes call by
    reference).

(2) In pipe_stat(), lock the pipe if MAC is compiled in so that
    the call to mac_check_pipe_stat() gets a locked pipe to
    protect label consistency.  We still release the lock before
    returning actual stat() data, risking inconsistency, but
    apparently our pipe locking model accepts that risk.

(3) In various pipe MAC authorization checks, assert that the pipe
    lock is held.

(4) Grab the lock when performing a pipe relabel operation, and
    assert it a little deeper in the stack.

4499985ef2 Reserve system call numbers for the following system calls:
__mac_get_pid		Retrieve MAC label of a process by pid

Similar to __mac_get_proc() except that the target process of
the operation is explicitly specified rather than assuming
curthread.

__mac_get_link		Retrieve MAC label of a path with NOFOLLOW
__mac_set_link		Set MAC label of a path with NOFOLLOW
extattr_set_link	Set EAs on a path with NOFOLLOW
extattr_get_link	Retrieve EAs on a path with NOFOLLOW
extattr_delete_link	Delete EAs on a path with NOFOLLOW

These calls are similar to __mac_get_file(), __mac_set_file(),
extattr_set_file(), extattr_get_file(), and extattr_delete_file(),
except that they do not follow symlinks.  The distinction between
these calls is similar to lchown() vs chown().

Implementations to follow.

226e1171e1 (Forced commit, to clarify previous commit of ksiginfo/signal queue code.)
I've added a structure, kernel-private, to represent a pending or in-delivery
signal, called `ksiginfo'.  It is roughly analogous to the basic information
that is exported by the POSIX interface 'siginfo_t', but more basic.  I've
added functions to allocate these structures, and further to wrap all signal
operations using them.

Once the operations are wrapped, I've added a TailQ (see queue(3)) of these
structures to 'struct proc', and all pending signals are in that TailQ.  When
a signal is being delivered, it is dequeued from the list.  Once I finish
the spreading of ksiginfo throughout the tree, the dequeued structure will be
delivered to the process in question, whereas currently and normally, the
signal number is what is used.

1226f694e6 First half of implementation of ksiginfo, signal queues, and such. This
gets signals operating based on a TailQ, and is good enough to run X11,
GNOME, and do job control.  There are some intricate parts which could be
more refined to match the sigset_t versions, but those require further
evaluation of directions in which our signal system can expand and contract
to fit our needs.

After this has been in the tree for a while, I will make in kernel API
changes, most notably to trapsignal(9) and sendsig(9), to use ksiginfo
more robustly, such that we can actually pass information with our
(queued) signals to the userland.  That will also result in using a
struct ksiginfo pointer, rather than a signal number, in a lot of
kern_sig.c, to refer to an individual pending signal queue member, but
right now there is no defined behaviour for such.

CODAFS is unfinished in this regard because the logic is unclear in
some places.

a84db8f49e Guido found another bug. There is a situation with
timestamped TCP packets where FreeBSD will send DATA+FIN and
A W2K box will ack just the DATA portion.  If this occurs
after FreeBSD has done a (NewReno) fast-retransmit and is
recovering it (dupacks > threshold) it triggers a case in
tcp_newreno_partial_ack() (tcp_newreno() in stable) where
tcp_output() is called with the expectation that the retransmit
timer will be reloaded.  But tcp_output() falls through and
returns without doing anything, causing the persist timer to be
loaded instead.  This causes the connection to hang until W2K gives up.
This occurs because in the case where only the FIN must be acked, the
'len' calculation in tcp_output() will be 0, a lot of checks will be
skipped, and the FIN check will also be skipped because it is designed
to handle FIN retransmits, not forced transmits from tcp_newreno().

The solution is to simply set TF_ACKNOW before calling tcp_output()
to absolute guarentee that it will run the send code and reset the
retransmit timer.  TF_ACKNOW is already used for this purpose in other
cases.

For some unknown reason this patch also seems to greatly reduce
the number of duplicate acks received when Guido runs his tests over
a lossy network.  It is quite possible that there are other
tcp_newreno{_partial_ack()} cases which were not generating the expected
output which this patch also fixes.

fe74650816 In rev 1.51 of usb_port.h I switched over to using the USB_USE_SOFTINTR
code path to fix a bug in the non USB_USE_SOFTINTR path that caused
the usb bus to hang and generally misbehave when devices were unplugged.
In the process though it also reduced the throughput of usb devices because
of a less than optimal implementation under FreeBSD.

This commit fixes the non USB_USE_SOFTINTR code in uhci and ohci
so that it works again, and switches back to using this code path.

The uhci code has been tested, but the ohci code hasn't.  It's
essentially the same anyway and so I don't envisage any difficulties.
