94fdcc2ee8 Modify ipxsocket regression test to create and close sockets several
times, with variable length sleeps between socket() and close().  This
will help to ensure that IPX/SPX timers fire while the sockets are
open, and hence have PCB's on the IPX pcb list, so that if timers are
going to stumble over PCB types they don't expect, it will happen as
part of this test.

722542bc34 Add a new ipxpcb flag, IPXP_SPX, which is set on ipxpcb's to mark them
as belonging to SPX.  This replaces the implicit assumption that the cb
pointer for non-SPX pcb's will be NULL.  This isn't required in TCP/IP
as different pcb lists are maintained for different IP protocols; IPX
stores all pcbs on the same global ipxpcb_list.

49874f6ea3 MFP4: Support for profiling dynamically loaded objects.
Kernel changes:

  Inform hwpmc of executable objects brought into the system by
  kldload() and mmap(), and of their removal by kldunload() and
  munmap().  A helper function linker_hwpmc_list_objects() has been
  added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve
  the list of currently loaded kernel modules.

  The unused `MAPPINGCHANGE' event has been deprecated in favour
  of separate `MAP_IN' and `MAP_OUT' events; this change reduces
  space wastage in the log.

  Bump the hwpmc's ABI version to "2.0.00".  Teach hwpmc(4) to
  handle the map change callbacks.

  Change the default per-cpu sample buffer size to hold
  32 samples (up from 16).

  Increment __FreeBSD_version.

libpmc(3) changes:

  Update libpmc(3) to deal with the new events in the log file; bring
  the pmclog(3) manual page in sync with the code.

pmcstat(8) changes:

  Introduce new options to pmcstat(8): "-r" (root fs path), "-M"
  (mapfile name), "-q"/"-v" (verbosity control).  Option "-k" now
  takes a kernel directory as its argument but will also work with
  the older invocation syntax.

  Rework string handling in pmcstat(8) to use an opaque type for
  interned strings.  Clean up ELF parsing code and add support for
  tracking dynamic object mappings reported by a v2.0.00 hwpmc(4).

  Report statistics at the end of a log conversion run depending
  on the requested verbosity level.

6882aa2c03 Define two new inpcb flags in the inp_vflag field, which for whatever
reason, seems to be where new flags are getting defined:

INP_DROPPED - The protocol has terminated this connection and the socket
              is not reusable: when the socket code enters the protocol,
              an error is immediately returned.  This will substitute for
              NULLing the so_pcb socket field, helping to implement the
              invariant that all valid sockets have valid pcb's in TCP.

INP_SOCKREF - The protocol has become the owner of the socket reference,
              and will need to free it when freeing the pcb, which will
              be used when a TCP socket is closed but still has queued
              data.

a529c6a2dc Correct bad format args. Interesting- the lines that generated
the error on sparc64 hadn't changed since the last checkin, pass
LINT on other platforms and mpt doesn't work on sparc64 anyway
and the tinderbox build didn't work for me in a cross build case
on my main build machine (which runs RELENG_6). Sigh. Still
need to try harder.

818812244b Rework IPX/SPX socket and pcb reference model:
- Introduce invariant that all IPX/SPX sockets will have valid so_pcb
  pointers to ipxpcb structures, and that for SPX, the control block
  pointer will always be valid.  Don't attempt to free the socket or
  pcb at various odd points, such as disconnect.

- Add a new ipxpcb flag, IPXP_DROPPED, which will be set in place of
  freeing PCB's so that this invariant can be maintained.  This flag
  is now checked instead of a NULL check in various socket protocol
  calls.

- Introduce many assertions that this invariant holds.

- Various pieces of code, such as the SPX timer code, no longer needs
  to jump through hoops in case it frees a PCB while running.

- Break out ipx_pcbfree() from ipx_pcbdetach().  Likewise
  spx_pcbdetach().

- Comment on some SMP-related limitations to the SPX code.

- Update copyrights.

c87e3f833c Some fairly major changes to this driver.
A) Fibre Channel Target Mode support mostly works
(SAS/SPI won't be too far behind). I'd say that
this probably works just about as well as isp(4)
does right now. Still, it and isp(4) and the whole
target mode stack need a bit of tightening.

B) The startup sequence has been changed so that
after all attaches are done, a set of enable functions
are called. The idea here is that the attaches do
whatever needs to be done *prior* to a port being
enabled and the enables do what need to be done for
enabling stuff for a port after it's been enabled.

This means that we also have events handled by their
proper handlers as we start up.

C) Conditional code that means that this driver goes
back all the way to RELENG_4 in terms of support.

D) Quite a lot of little nitty bug fixes- some discovered
by doing RELENG_4 support. We've been living under Giant
*waaaayyyyy* too long and it's made some of us (me) sloppy.

E) Some shutdown hook stuff that makes sure we don't blow
up during a reboot (like by the arrival of a new command
from an initiator).

There's been some testing and LINT checking, but not as
complete as would be liked. Regression testing with Fusion
RAID instances has not been possible. Caveat Emptor.

045b6fdaf6 Make gcore(1) 64 bit safe. It was trying to parse the /proc/*/map file
using sscanf and truncating the start/end entries by writing them with a
32 bit int descriptor (%x).  The upper bytes of the 64 bit vm_offset_t
variables (for little endian machines) were uninitialized.  For big endian
machines, things would have been worse because it was storing the 32 bit
value in the upper half of the 64 bit variable.  I've changed it to use
%lx and long types.  That should work on all our platforms.

0c21f9eda7 Convert TINY_MIN_2POW from a cpp macro to tiny_min_2pow (a variable), and
determine its value at run time according to other relevant values.  This
avoids the creation of runs that are incompletely utilized, as long as
pagesize isn't too large (>32kB, given the current RUN_MIN_REGS_2POW
setting).

Increase the size of several structure bitfields in arena_run_t in order
to avoid integer overflow in the case that a run's header does not overlap
with the space that is usable as application allocation regions.  Given
the tiny_min_2pow change, this fix has no additional impact unless
pagesize is >32kB.

86cca1e75e Fix a bug such that if you enabled sorting by size (-S) and enabled a

actually be sorted by the specified time rather than size.  This does
alter the behavior in the case where both -S and -t are specified.  Now,
-S is always preferred.  Previously, -t was preferred if one of -c, -u, or
-U was specified, and -S was preferred otherwise.  Perhaps -S and -t should
override each other (last one specified wins).

lowest voltage supported by both the card and the socket.
