6e21afd40c Add two new function pointers 'lc_lock' and 'lc_unlock' to lock classes.
These functions are intended to be used to drop a lock and then reacquire
it when doing an sleep such as msleep(9).  Both functions accept a
'struct lock_object *' as their first parameter.  The 'lc_unlock' function
returns an integer that is then passed as the second paramter to the
subsequent 'lc_lock' function.  This can be used to communicate state.
For example, sx locks and rwlocks use this to indicate if the lock was
share/read locked vs exclusive/write locked.

Currently, spin mutexes and lockmgr locks do not provide working lc_lock
and lc_unlock functions.

f9feee175b KERN_PROC_ALL produces a kinfo_proc for each thread in a process, which
caused fstat to produce duplicated output for threaded processes.  Instead
use KERN_PROC_PROC to get just one kinfo_proc per process.

557158de64 - style.Makefile(9) fix
- first line is $FreeBSD$
  - Reorder special variables: DPADD, LPADD, CFLAGS
  - Use = instead of += for variables that are initially empty
  - Use space instead of tab after :
  - Use one tab after =
- Use .SUFFIXES for section 3 manual page which simplifies Makefile a lot
- Use SHAREDIR instead of /usr/share
- Remove SRCDIR in INCS since we set .PATH properly
- Use plural in variable name when it stands for more that one source file

f9bb753844 Over NFS, an open() call could result in multiple over-the-wire
GETATTRs being generated - one from lookup()/namei() and the other
from nfs_open() (for cto consistency). This change eliminates the
GETATTR in nfs_open() if an otw GETATTR was done from the namei()
path. Instead of extending the vop interface, we timestamp each attr
load, and use this to detect whether a GETATTR was done from namei()
for this syscall. Introduces a thread-local variable that counts the
syscalls made by the thread and uses <pid, tid, thread syscalls> as
the attrload timestamp. Thanks to jhb@ and peter@ for a discussion on
thread state that could be used as the timestamp with minimal overhead.

   and INADDR_ANY, to disallow possible collisions with existing udp inpcbs
   bound to the same port on other interfaces at send time.

 * If the socket is bound to INADDR_ANY, specifying IP_SENDSRCADDR with
   INADDR_ANY will be rejected as it is ambiguous.

 * If the socket is bound to an address other than INADDR_ANY, specifying
   IP_SENDSRCADDR with INADDR_ANY will be disallowed by in_pcbbind_setup().

9a81351403 Implement "Remaking Makefiles" feature:
After reading Makefile and all the files that are included using .include
or .sinclude directives (source Makefiles) make considers each source
Makefile as a target and tries to rebuild it.  Both explicit and implicit
rules are checked and all source Makefiles are updated if necessary. If
any of the source Makefiles were rebuilt, make restarts from clean state.

To prevent infinite loops the following source Makefile targets are
ignored:
- :: targets that have no prerequisites but have commands
- ! targets
- targets that have .PHONY or .EXEC attributes
- targets without prerequisites and without commands

When remaking a source Makefile options -t (touch target), -q (query
mode), and -n (no exec) do not take effect, unless source Makefile is
specified explicitly as a target in make command line.
Additionally, system makefiles and .depend are not considered as a
Makefiles that can be rebuilt.

d4c6c416dc New tests for system-independent ACL support.
These tests verify that archive_entry objects can store and return
ACL data and that pax format archives can read and write ACL
information.  These do not (yet) test that ACL data is read or
written to disk correctly.  (And hence would not have caught the
recent snafu about ACL read-from-disk being turned off.)

19dd89364c Distinguish between the end of ACL data and an error in pulling

archive_read_extract or archive_write_disk since they only
check for != ARCHIVE_OK when calling this function.  (Though
they should be more careful.)

95ad8418dc This patch is provided to fix a couple of deployment issues observed
in the field. In one situation, one end of the TCP connection sends
a back-to-back RST packet, with delayed ack, the last_ack_sent variable
has not been update yet. When tcp_insecure_rst is turned off, the code
treats the RST as invalid because last_ack_sent instead of rcv_nxt is
compared against th_seq. Apparently there is some kind of firewall that
sits in between the two ends and that RST packet is the only RST
packet received. With short lived HTTP connections, the symptom is
a large accumulation of connections over a short period of time .

The +/-(1) factor is to take care of implementations out there that
generate RST packets with these types of sequence numbers. This
behavior has also been observed in live environments.

33368e9fe8 Rototill the sparc64 nexus(4) (actually this brings in the code the
sun4v nexus(4) in turn is based on):
o Change nexus(4) to manage the resources of its children so the
  respective device drivers don't need to figure them out of OFW
  themselves.
o Change nexus(4) to provide the ofw_bus KOBJ interface instead of
  using IVARs for supplying the OFW node and the subset of standard
  properties of its children. Together with the previous change this
  also allows to fully take advantage of newbus in that drivers like
  fhc(4), which attach on multiple parent busses, no longer require
  different bus front-ends as obtaining the OFW node and properties
  as well as resource allocation works the same for all supported
  busses. As such this change also is part 4/4 of allowing creator(4)
  to work in USIII-based machines as it allows this driver to attach
  on both nexus(4) and upa(4). On the other hand removing these IVARs
  breaks API compatibility with the powerpc nexus(4) but which isn't
  that bad as a) sparc64 currently doesn't share any device driver
  hanging off of nexus(4) with powerpc and b) they were no longer
  compatible regarding OFW-related extensions at the pci(4) level
  since quite some time.
o Provide bus_get_dma_tag methods in nexus(4) and its children in
  order to handle DMA tags in a hierarchical way and get rid of the
  sparc64_root_dma_tag kludge. Together with the previous two items
  this changes also allows to completely get rid of the nexus(4)
  IVAR interface. It also includes:
  - pushing the constraints previously specified by the nexus_dmatag
    down into the DMA tags of psycho(4) and sbus(4) as it's their
    IOMMUs which induce these restrictions (and nothing at the
    nexus(4) or anything that would warrant specifying them there),
  - fixing some obviously wrong constraints of the psycho(4) and
    sbus(4) DMA tags, which happened to not actually be used with
    the sparc64_root_dma_tag kludge in place and therefore didn't
    cause problems so far,
  - replacing magic constants for constraints with macros as far
    as it is obvious as to where they come from.
  This doesn't include taking advantage of the newbus way to get
  the parent DMA tags implemented by this change in order to divorce
  the IOTSBs of the PCI and SBus IOMMUs or for implementing the
  workaround for the DMA sync bug in Sabre (and Tomatillo) bridges,
  yet, though.
o Get rid of the notion that nexus(4) (mostly) reflects an UPA bus
  by replacing ofw_upa.h and with ofw_nexus.h (which was repo-copied
  from ofw_upa.h) and renaming its content, which actually applies to
  all of Fireplane/Safari, JBus and UPA (in the host bus case), as
  appropriate.
o Just use M_DEVBUF instead of a separate M_NEXUS malloc type for
  allocating the device info for the children of nexus(4). This is
  done in order to not need to export M_NEXUS when deriving drivers
  for subordinate busses from the nexus(4) class.
o Use the DEFINE_CLASS_0() macro to declare the nexus(4) driver so
  we can derive subclasses from it.
o Const'ify the nexus_excl_name and nexus_excl_type arrays as well
  as add 'associations' and 'rsc', which are pseudo-devices without
  resources and therefore of no real interest for nexus(4), to the
  former.
o Let the nexus(4) device memory rman manage the entire 64-bit address
  space instead of just the UPA_MEMSTART to UPA_MEMEND subregion as
  Fireplane/Safari- and JBus-based machines use multiple ranges,
  which can't be as easily divided as in the case of UPA (limiting
  the address space only served for sanity checking anyway).
o Use M_WAITOK instead of M_NOWAIT when allocating the device info
  for children of nexus(4) in order to give one less opportunity
  for adding devices to nexus(4) to fail.
o While adapting the drivers affected by the above nexus(4) changes,
  change them to take advantage of rman_get_rid() instead of caching
  the RIDs assigned to allocated resources, now that the RIDs of
  resources are correctly set.
o In iommu(4) and nexus(4) replace hard-coded functions names, which
  actually became outdated in several places, in panic strings and
  status massages with __func__. [1]
o Use driver_filter_t in prototypes where appropriate.
o Add my copyright to creator(4), fhc(4), nexus(4), psycho(4) and
  sbus(4) as I changed considerable amounts of these drivers as well
  as added a bunch of new features, workarounds for silicon bugs etc.
o Fix some white space nits.

Due to lack of access to Exx00 hardware, these changes, i.e. central(4)
and fhc(4), couldn't be runtime tested on such a machine. Exx00 are
currently reported to panic before trying to attach nexus(4) anyway
though.
