026e76f43e Close a race condition where if we were obtaining a sleep lock and no spin
locks were held, we could be preempted and switch CPU's in between the time
that we set a variable to the list of spin locks on our CPU and the time
that we checked that variable to ensure no spinlocks were held while
grabbing a sleep lock.  Losing the race resulted in checking some other
CPU's spin lock list and bogusly panicing.

192846463a Rework the witness code to work with sx locks as well as mutexes.
- Introduce lock classes and lock objects.  Each lock class specifies a
  name and set of flags (or properties) shared by all locks of a given
  type.  Currently there are three lock classes: spin mutexes, sleep
  mutexes, and sx locks.  A lock object specifies properties of an
  additional lock along with a lock name and all of the extra stuff needed
  to make witness work with a given lock.  This abstract lock stuff is
  defined in sys/lock.h.  The lockmgr constants, types, and prototypes have
  been moved to sys/lockmgr.h.  For temporary backwards compatability,
  sys/lock.h includes sys/lockmgr.h.
- Replace proc->p_spinlocks with a per-CPU list, PCPU(spinlocks), of spin
  locks held.  By making this per-cpu, we do not have to jump through
  magic hoops to deal with sched_lock changing ownership during context
  switches.
- Replace proc->p_heldmtx, formerly a list of held sleep mutexes, with
  proc->p_sleeplocks, which is a list of held sleep locks including sleep
  mutexes and sx locks.
- Add helper macros for logging lock events via the KTR_LOCK KTR logging
  level so that the log messages are consistent.
- Add some new flags that can be passed to mtx_init():
  - MTX_NOWITNESS - specifies that this lock should be ignored by witness.
    This is used for the mutex that blocks a sx lock for example.
  - MTX_QUIET - this is not new, but you can pass this to mtx_init() now
    and no events will be logged for this lock, so that one doesn't have
    to change all the individual mtx_lock/unlock() operations.
- All lock objects maintain an initialized flag.  Use this flag to export
  a mtx_initialized() macro that can be safely called from drivers.  Also,
  we on longer walk the all_mtx list if MUTEX_DEBUG is defined as witness
  performs the corresponding checks using the initialized flag.
- The lock order reversal messages have been improved to output slightly
  more accurate file and line numbers.

- On the alpha we no longer need a custom _get_spin_lock() macro to avoid

- Partially fix using mutexes with WITNESS in modules.  Change all the

  parameters and rename them to use a prefix of two underscores.  Inside
  of kern_mutex.c, generate wrapper functions for
  _mtx_{un,}lock_{spin,}_flags() (only using a prefix of one underscore)
  that are called from modules.  The macros mtx_{un,}lock_{spin,}_flags()
  are mapped to the __mtx_* macros inside of the kernel to inline the
  usual case of mutex operations and map to the internal _mtx_* functions
  in the module case so that modules will use WITNESS and KTR logging if

919eea6db9 Check whether we need to do a full restore after handling ASTs. If
an AST results in a signal being delivered, we'll need to do a full register
restore so as to properly setup the signal handler.  This is somewhat of
a pessimization, because ast() will be called twice in this case.

This fixes several problems that have been reported where signal intensive
userland apps (most notably dump) have been SEGV'ing for no fault of their
own.

Thanks to Peter Jeremy <peter.jeremy@alcatel.com.au> for presenting the
AST scenario which led to me fiinally figuring this out.

3393f8daa3 Rewrite of the CAM error recovery code.
Some of the major changes include:

	- The SCSI error handling portion of cam_periph_error() has
	  been broken out into a number of subfunctions to better
	  modularize the code that handles the hierarchy of SCSI errors.
	  As a result, the code is now much easier to read.

	- String handling and error printing has been significantly
	  revamped.  We now use sbufs to do string formatting instead
	  of using printfs (for the kernel) and snprintf/strncat (for
	  userland) as before.

	  There is a new catchall error printing routine,
	  cam_error_print() and its string-based counterpart,
	  cam_error_string() that allow the kernel and userland
	  applications to pass in a CCB and have errors printed out
	  properly, whether or not they're SCSI errors.  Among other
	  things, this helped eliminate a fair amount of duplicate code
	  in camcontrol.

	  We now print out more information than before, including
	  the CAM status and SCSI status and the error recovery action
	  taken to remedy the problem.

	- sbufs are now available in userland, via libsbuf.  This
	  change was necessary since most of the error printing code
	  is shared between libcam and the kernel.

	- A new transfer settings interface is included in this checkin.
	  This code is #ifdef'ed out, and is primarily intended to aid
	  discussion with HBA driver authors on the final form the
	  interface should take.  There is example code in the ahc(4)
	  driver that implements the HBA driver side of the new
	  interface.  The new transfer settings code won't be enabled
	  until we're ready to switch all HBA drivers over to the new
	  interface.

src/Makefile.inc1,
lib/Makefile:		Add libsbuf.  It must be built before libcam,
			since libcam uses sbuf routines.

libcam/Makefile:	libcam now depends on libsbuf.

libsbuf/Makefile:	Add a makefile for libsbuf.  This pulls in the
			sbuf sources from sys/kern.

bsd.libnames.mk:	Add LIBSBUF.

camcontrol/Makefile:	Add -lsbuf.  Since camcontrol is statically
			linked, we can't depend on the dynamic linker
			to pull in libsbuf.

camcontrol.c:		Use cam_error_print() instead of checking for
			CAM_SCSI_STATUS_ERROR on every failed CCB.

sbuf.9:			Change the prototypes for sbuf_cat() and
			sbuf_cpy() so that the source string is now a
			const char *.  This is more in line wth the
			standard system string functions, and helps
			eliminate warnings when dealing with a const
			source buffer.

			Fix a typo.

cam.c:			Add description strings for the various CAM
			error status values, as well as routines to
			look up those strings.

			Add new cam_error_string() and
			cam_error_print() routines for userland and
			the kernel.

cam.h:			Add a new CAM flag, CAM_RETRY_SELTO.

			Add enumerated types for the various options
			available with cam_error_print() and
			cam_error_string().

cam_ccb.h:		Add new transfer negotiation structures/types.

			Change inq_len in the ccb_getdev structure to
			be "reserved".  This field has never been
			filled in, and will be removed when we next
			bump the CAM version.

cam_debug.h:		Fix typo.

cam_periph.c:		Modularize cam_periph_error().  The SCSI error
			handling part of cam_periph_error() is now
			in camperiphscsistatuserror() and
			camperiphscsisenseerror().

			In cam_periph_lock(), increase the reference
			count on the periph while we wait for our lock
			attempt to succeed so that the periph won't go
			away while we're sleeping.

cam_xpt.c:		Add new transfer negotiation code.  (ifdefed
			out)

			Add a new function, xpt_path_string().  This
			is a string/sbuf analog to xpt_print_path().

scsi_all.c:		Revamp string handing and error printing code.
			We now use sbufs for much of the string
			formatting code.  More of that code is shared
			between userland the kernel.

scsi_all.h:		Get rid of SS_TURSTART, it wasn't terribly
			useful in the first place.

			Add a new error action, SS_REQSENSE.  (Send a
			request sense and then retry the command.)
			This is useful when the controller hasn't
			performed autosense for some reason.

			Change the default actions around a bit.

scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.  Selection
			timeouts shouldn't be covered by a sense flag.

scsi_pass.[ch]:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.

			Get rid of the last vestiges of a read/write
			interface.

libkern/bsearch.c,
sys/libkern.h,
conf/files:		Add bsearch.c, which is needed for some of the
			new table lookup routines.

aic7xxx_freebsd.c:	Define AHC_NEW_TRAN_SETTINGS if
			CAM_NEW_TRAN_CODE is defined.

sbuf.h,
subr_sbuf.c:		Add the appropriate #ifdefs so sbufs can
			compile and run in userland.

			Change sbuf_printf() to use vsnprintf()
			instead of kvprintf(), which is only available
			in the kernel.

			Change the source string for sbuf_cpy() and
			sbuf_cat() to be a const char *.

			Add __BEGIN_DECLS and __END_DECLS around
			function prototypes since they're now exported
			to userland.

kdump/mkioctls:		Include stdio.h before cam.h since cam.h now
			includes a function with a FILE * argument.

a70f27470f Introduce support for POSIX.1e ACLs on UFS-based file systems. This
implementation is still experimental, and while fairly broadly tested,
is not yet intended for production use.  Support for POSIX.1e ACLs on
UFS will not be MFC'd to RELENG_4.

This implementation works by providing implementations of VOP_[GS]ETACL()
for FFS, as well as modifying the appropriate access control and file
creation routines.  In this implementation, ACLs are backed into extended
attributes; the base ACL (owner, group, other) permissions remain in the
inode for performance and compatibility reasons, so only the extended and
default ACLs are placed in extended attributes.  The logic for ACL
evaluation is provided by the fs-independent kern/kern_acl.c.

o Introduce UFS_ACL, a compile-time configuration option that enables
  support for ACLs on FFS (and potentially other UFS-based file systems).
o Introduce ufs_getacl(), ufs_setacl(), ufs_aclcheck(), which
  respectively get, set, and check the ACLs on the passed vnode.
o Introduce ufs_sync_acl_from_inode(), ufs_sync_inode_from_acl() to
  maintain access control information between inode permissions and
  extended attribute data.
o Modify ufs_access() to load a file access ACL and invoke
  vaccess_acl_posix1e() if ACLs are available on the file system
o Modify ufs_mkdir() and ufs_makeinode() to associate ACLs with newly
  created directories and files, inheriting from the parent directory's
  default ACL.
o Enable these new vnode operations and conditionally compiled code
  paths if UFS_ACL is defined.

A few notes:

o This implementation is fairly widely tested, but still should be
  considered experimental.
o Currently, ACLs are not exported via NFS, instead, the summarizing
  file mode/etc from the inode is.  This results in conservative
  protection behavior, similar to the behavior of ACL-nonaware programs
  acting locally.
o It is possible that underlying binary data formats associated with
  this implementation may change.  Consumers of the implementation
  should expect to find their local configuration obsoleted in the
  next few months, resulting in possible loss of ACL data during an
  upgrade.
o The extended attributes interface and implementation is still
  undergoing modification to address portable interface concerns, as
  well as performance.
o Many applications do not yet correctly handle ACLs.  In general,
  due to the POSIX.1e ACL model, behavior of ACL-unaware applications
  will be conservative with respects to file protection; some caution
  is recommended.
o Instructions for configuring and maintaining ACLs on UFS will be
  committed in the near future; in the mean time it is possible to
  reference the README included in the last UFS ACL distribution
  placed in the TrustedBSD web site:

      http://www.TrustedBSD.org/downloads/

Merge rev's 1.65 and 1.66 from sys/net/if_spppsubr.c (implement the
`restart' option, and fix a blatant bug with PAP authentication).

The i4b implementation of this file should be merged back, but for now,
we need this here as well.

Fix a serious bug in sppp where anyone could obtain a successful PAP
authentication by supplying a null password.  I've only stumpled across

Should we also file a security advisory for this?

66ef8af5b0 mega-commit.
this introduces a new buffering mechanism which results in dramatic
simplification of the channel manager.

as several structures have changed, we take the opportunity to move their
definitions into the source files where they are used, make them private and
de-typedef them.

the sound drivers are updated to use snd_setup_intr instead of
bus_setup_intr, and to comply with the de-typedefed structures.

the ac97, mixer and channel layers have been updated with finegrained
locking, as have some drivers- not all though.  the rest will follow soon.

32e479705a This is kind of a hack, but it should work. Currently, world is broken
because libc/rpc/key_call.c references uname(), and ps/print.c also
defines uname(), and ps is linked statically.  This leads to a symbol
clash.  The userland uname(3) kinda sucked anyway as the hostname
etc was too short.  And since the libc rpc interface now uses
the utsname.nodename which gets truncated, I was tempted into doing
something about it.  Create a new userland uname function, called
__xuname() which takes an extra argument that allows you to change
the size of the fields.  uname() becomes a static inline function
in sys/utsname.h that passes the extra argument in.  struct utsname
has its field members expanded by default now in userland.
We still provide a 'uname' externally linkable function for things
that either think that they ``know'' the utsname format and assume
32 character strings and bypass the include file, or objects that
are linked against old libcs.  ie: just about every plausible
case that I can think of is covered.  Should we ever change the
default lengths again, a libc major bump should not be required
as the size is now passed to the function.

XXX the uname(2) in the kernel is for FreeBSD 1.1 binary compatability!
All the uname(3) functions that are exported to userland are actually
implemented in libc with sysctl.  uname(1) uses sysctl directly and
does not call uname(3).

8d21ca78d9 (MFC candidate, see below).
When we get an Open event in stopped state, experience shows that this
is usually means we've somehow missed a previous Down event.  This has
occasionally bitten people for the IPCP layer with ISDN, apparently a
previously aborted IPCP negotiation must have caused this.  As a
bandaid, we quickly pretent a Down event by advancing to starting
state; this effectively implements the `restart' option mentioned in
RFC 1663.

While i'm not yet fully convinced this is the best thing to do (and is
fully compliant with RFC 1661), i've seen a number of reports here on
the German mailing lists where people have been bitten by the previous
behaviour which usually causes quickly looping ISDN reconnects (thus
loss of money...), and where just this patch fixes the problem.

For this, i'd even like to see it MFC'd if possible.
