a78c3ed89c Remove the sbsh(4) driver. No one responded to requests for testing the
MPSAFE patches on current@ and stable@.  This driver also has a fundamental
issue in that it sleeps when sending commands to the card including in the
if_init/if_start routines (which can be called from interrupt context).  As
such, the driver shouldn't be working reliably even on 4.x.

2c6298572e Remove the oltr(4) driver. No one responded to calls for testing on
current@ and stable@ for the locking patches.  The driver can always be
revived if someone tests it.

This driver also sleeps in its if_init routine, so it likely doesn't really
work at all anyway in modern releases.

6bc1e9cd84 Rework the lifetime management of the kernel implementation of POSIX
semaphores.  Specifically, semaphores are now represented as new file
descriptor type that is set to close on exec.  This removes the need for
all of the manual process reference counting (and fork, exec, and exit
event handlers) as the normal file descriptor operations handle all of
that for us nicely.  It is also suggested as one possible implementation
in the spec and at least one other OS (OS X) uses this approach.

Some bugs that were fixed as a result include:
- References to a named semaphore whose name is removed still work after
  the sem_unlink() operation.  Prior to this patch, if a semaphore's name
  was removed, valid handles from sem_open() would get EINVAL errors from
  sem_getvalue(), sem_post(), etc.  This fixes that.
- Unnamed semaphores created with sem_init() were not cleaned up when a
  process exited or exec'd.  They were only cleaned up if the process
  did an explicit sem_destroy().  This could result in a leak of semaphore
  objects that could never be cleaned up.
- On the other hand, if another process guessed the id (kernel pointer to
  'struct ksem' of an unnamed semaphore (created via sem_init)) and had
  write access to the semaphore based on UID/GID checks, then that other
  process could manipulate the semaphore via sem_destroy(), sem_post(),
  sem_wait(), etc.
- As part of the permission check (UID/GID), the umask of the proces
  creating the semaphore was not honored.  Thus if your umask denied group
  read/write access but the explicit mode in the sem_init() call allowed
  it, the semaphore would be readable/writable by other users in the
  same group, for example.  This includes access via the previous bug.
- If the module refused to unload because there were active semaphores,
  then it might have deregistered one or more of the semaphore system
  calls before it noticed that there was a problem.  I'm not sure if
  this actually happened as the order that modules are discovered by the
  kernel linker depends on how the actual .ko file is linked.  One can
  make the order deterministic by using a single module with a mod_event
  handler that explicitly registers syscalls (and deregisters during
  unload after any checks).  This also fixes a race where even if the
  sem_module unloaded first it would have destroyed locks that the
  syscalls might be trying to access if they are still executing when
  they are unloaded.

  XXX: By the way, deregistering system calls doesn't do any blocking
  to drain any threads from the calls.
- Some minor fixes to errno values on error.  For example, sem_init()
  isn't documented to return ENFILE or EMFILE if we run out of semaphores
  the way that sem_open() can.  Instead, it should return ENOSPC in that
  case.

Other changes:
- Kernel semaphores now use a hash table to manage the namespace of
  named semaphores nearly in a similar fashion to the POSIX shared memory
  object file descriptors.  Kernel semaphores can now also have names
  longer than 14 chars (up to MAXPATHLEN) and can include subdirectories
  in their pathname.
- The UID/GID permission checks for access to a named semaphore are now
  done via vaccess() rather than a home-rolled set of checks.
- Now that kernel semaphores have an associated file object, the various
  MAC checks for POSIX semaphores accept both a file credential and an
  active credential.  There is also a new posixsem_check_stat() since it
  is possible to fstat() a semaphore file descriptor.
- A small set of regression tests (using the ksem API directly) is present
  in src/tools/regression/posixsem.

provides the correct semantics for flock(2) style locks which are used by the
lockf(1) command line tool and the pidfile(3) library. It also implements
recovery from server restarts and ensures that dirty cache blocks are written
to the server before obtaining locks (allowing multiple clients to use file
locking to safely share data).

20e8415eb4 This delta has a few important items:
PR 122839 is fixed in both em and in igb

Second, the issue on building modules since the static kernel
build changes is now resolved. I was not able to get the fancier
directory hierarchy working, but this works, both em and igb
build as modules now.

Third, there is now support in em for two new NICs, Hartwell
(or 82574) is a low cost PCIE dual port adapter that has MSIX,
for this release it uses 3 vectors only, RX, TX, and LINK. In
the next release I will add a second TX and RX queue. Also, there
is support here for ICH10, the followon to ICH9. Both of these are
early releases, general availability will follow soon.

Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support,
I have implemented this in a provisional way so that early adopters
may try and comment on the functionality. The IOCTL structure may
change. This feature is off by default, you need to edit the Makefile
and add the EM_TIMESYNC define to get the code.

Enjoy all!!

f75ef9e44f This change introduces a split to the Intel E1000 driver, now rather than
just em, there is an igb driver (this follows behavior with our Linux drivers).
All adapters up to the 82575 are supported in em, and new client/desktop support
will continue to be in that adapter.

The igb driver is for new server NICs like the 82575 and its followons.
Advanced features for virtualization and performance will be in this driver.

Also, both drivers now have shared code that is up to the latest we have
released. Some stylistic changes as well.

44abffb44b Rather than having the Coda module use its own namecache, use the global
VFS namecache, as is done by the Coda module on Linux.  Unlike the Coda
namecache, the global VFS namecache isn't tagged by credential, so use
ore conservative flushing behavior (for now) when CODA_PURGEUSER is
issued by Venus.

This improves overall integration with the FreeBSD VFS, including
allowing __getcwd() to work better, procfs/procstat monitoring, and so
on.  This improves shell behavior in many cases, and improves ".."
handling.  It may lead to some slowdown until we've implemented a
specific access cache, which should net improve performance, but in the
mean time, lookup access control now always goes to Venus, whereas
previously it didn't.

3be4cb0b4a Merge Neterion if_nxge driver version 2.0.9.11230 with the following
changes:

  01 -  Enhanced LRO:
  LRO feature is extended to support multi-buffer mode. Previously,
  Ethernet frames received in contiguous buffers were offloaded.
  Now, frames received in multiple non-contiguous buffers can be
  offloaded, as well. The driver now supports LRO for jumbo frames.

  02 - Locks Optimization:
  The driver code was re-organized to limit the use of locks.
  Moreover, lock contention was reduced by replacing wait locks
  with try locks.

  03 - Code Optimization:
  The driver code was re-factored  to eliminate some memcpy
  operations.  Fast path loops were optimized.

  04 - Tag Creations:
  Physical Buffer Tags are now optimized based upon frame size.
  For better performance, Physical Memory Maps are now re-used.

  05 - Configuration:
  Features such as TSO, LRO, and Interrupt Mode can be configured
  either at load or at run time. Rx buffer mode (mode 1 or mode 2)
  can be configured at load time through kenv.

  06 - Driver Statistics:
  Run time statistics are enhanced to provide better visibility
  into the driver performance.

  07 - Bug Fixes:
  The driver contains fixes for the problems discovered and
  reported since last submission.

  08 - MSI support:
  Added Message Signaled Interrupt feature which currently uses 1
  message.

  09  Removed feature:
  Rx 3 buffer mode feature has been removed. Driver now supports 1,
  2 and 5 buffer modes of which 2 and 5 buffer modes can be used
  for header separation.

  10  Compiler warning:
  Fixed compiler warning when compiled for 32 bit system.

  11 Copyright notice:
  Source files are updated with the proper copyright notice.

1ed3fed743 o Revert the part of if_gem.c rev. 1.35 which added a call to gem_stop()
to gem_attach() as the former access softc members not yet initialized
  at that time and gem_reset() actually is enough to stop the chip. [1]
o Revise the use of gem_bitwait(); add bus_barrier() calls before calling
  gem_bitwait() to ensure the respective bit has been written before we
  starting polling on it and poll for the right bits to change, f.e. even
  though we only reset RX we have to actually wait for both GEM_RESET_RX
  and GEM_RESET_TX to clear. Add some additional gem_bitwait() calls in
  places we've been missing them according to the GEM documentation.
  Along with this some excessive DELAYs, which probably only were added
  because of bugs in gem_bitwait() and its use in the first place, as
  well as as have of an gem_bitwait() reimplementation in gem_reset_tx()
  were removed.
o Add gem_reset_rxdma() and use it to deal with GEM_MAC_RX_OVERFLOW errors
  more gracefully as unlike gem_init_locked() it resets the RX DMA engine
  only, causing no link loss and the FIFOs not to be cleared. Also use it
  deal with GEM_INTR_RX_TAG_ERR errors, with previously were unhandled.
  This was based on information obtained from the Linux GEM and OpenSolaris
  ERI drivers.
o Turn on workarounds for silicon bugs in the Apple GMAC variants.
  This was based on information obtained from the Darwin GMAC and Linux GEM
  drivers.
o Turn on "infinite" (i.e. maximum 31 * 64 bytes in length) DMA bursts.
  This greatly improves especially RX performance.
o Optimize the RX path, this consists of:
  - kicking the receiver as soon as we've a spare descriptor in gem_rint()
    again instead of just once after all the ready ones have been handled;
  - kicking the receiver the right way, i.e. as outlined in the GEM
    documentation in batches of 4 and by pointing it to the descriptor
    after the last valid one;
  - calling gem_rint() before gem_tint() in gem_intr() as gem_tint() may
    take quite a while;
  - doubling the size of the RX ring to 256 descriptors.
  Overall the RX performance of a GEM in a 1GHz Sun Fire V210 was improved
  from ~100Mbit/s to ~850Mbit/s.
o In gem_add_rxbuf() don't assign the newly allocated mbuf to rxs_mbuf
  before calling bus_dmamap_load_mbuf_sg(), if bus_dmamap_load_mbuf_sg()
  fails we'll free the newly allocated mbuf, unable to recycle the
  previous one but a NULL pointer dereference instead.
o In gem_init_locked() honor the return value of gem_meminit().
o Simplify gem_ringsize() and dont' return garbage in the default case.
  Based on OpenBSD.
o Don't turn on MAC control, MIF and PCS interrupts unless GEM_DEBUG is
  defined as we don't need/use these interrupts for operation.
o In gem_start_locked() sync the DMA maps of the descriptor rings before
  every kick of the transmitter and not just once after enqueuing all
  packets as the NIC might instantly start transmitting after we kicked
  it the first time.
o Keep state of the link state and use it to enable or disable the MAC
  in gem_mii_statchg() accordingly as well as to return early from
  gem_start_locked() in case the link is down. [3]
o Initialize the maximum frame size to a sane value.
o In gem_mii_statchg() enable carrier extension if appropriate.
o Increment if_ierrors in case of an GEM_MAC_RX_OVERFLOW error and in
  gem_eint(). [3]
o Handle IFF_ALLMULTI correctly; don't set it if we've turned promiscuous
  group mode on and don't clear the flag if we've disabled promiscuous
  group mode (these were mostly NOPs though). [2]
o Let gem_eint() also report GEM_INTR_PERR errors.
o Move setting sc_variant from gem_pci_probe() to gem_pci_attach() as
  device probe methods are not supposed to touch the softc.
o Collapse sc_inited and sc_pci into bits for sc_flags.
o Add CTASSERTs ensuring that GEM_NRXDESC and GEM_NTXDESC are set to
  legal values.
o Correctly set up for 802.3x flow control, though #ifdef out the code
  that actually enables it as this needs more testing and mainly a proper
  framework to support it.
o Correct and add some conversions from hard-coded functions names to
  __func__ which were borked or forgotten in if_gem.c rev. 1.42.
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o In gem_pci_attach() in case attaching fails release the resources in
  the opposite order they were allocated.
o Make gem_reset() static to if_gem.c as it's not needed outside that
  module.
o Remove the GEM_GIGABIT flag and the associated code; GEM_GIGABIT was
  never set and the associated code was in the wrong place.
o Remove sc_mif_config; it was only used to cache the contents of the
  respective register within gem_attach().
o Remove the #ifdef'ed out NetBSD/OpenBSD code for establishing a suspend
  hook as it will never be used on FreeBSD.
o Also probe Apple Intrepid 2 GMAC and Apple Shasta GMAC, add support for
  Apple K2 GMAC. Based on OpenBSD.
o Add support for Sun GBE/P cards, or in other words actually add support
  for cards based on GEM to gem(4). This mainly consists of adding support
  for the TBI of these chips. Along with this the PHY selection code was
  rewritten to hardcode the PHY number for certain configurations as for
  example the PHY of the on-board ERI of Blade 1000 shows up twice causing
  no link as the second incarnation is isolated.
  These changes were ported from OpenBSD with some additional improvements
  and modulo some bugs.
o Add code to if_gem_pci.c allowing to read the MAC-address from the VPD on
  systems without Open Firmware.
  This is an improved version of my variant of the respective code in
  if_hme_pci.c
o Now that gem(4) is MI enable it for all archs.

83dcc133d8 Rewrite the EC driver event model. The main goal is to avoid
polling/interrupt-driven fallback and instead use polling only during
boot and pure interrupt-driven mode after boot.  Polled mode could be
relegated completely to a legacy role if we could enable interrupts
during boot.  Polled mode can be forced after boot by setting
debug.acpi.ec.polled="1", i.e. if there are timeouts.

- Use polling only during boot, shutdown, or if requested by the user.
  Otherwise, use a generation count of GPEs, incremented atomically.  This
  prevents an old status value from being used if the EC is really slow
  and the same condition (i.e. multiple IBEs for a write transaction) is
  being checked.
- Check for and run the query handler directly if the SCI bit is set in
  the status register during boot.  Previously, the query handler wouldn't
  run until interrupts were finally enabled late in boot.
- During boot and after starting a command, check if the event appears
  to already have occurred before we even start waiting.  If so, it's
  possible the EC is very slow and we might accept an old status value.
  Print a warning in this case.  Once we've booted, interrupt-driven mode
  should work just fine but polled mode could be unreliable.  There's not
  much more we can do about this until interrupts are enabled during boot.
- In the above case, we also do one final check if the interrupt-driven
  mode gets a timeout.  If the status is complete, it will force the
  system back into polled mode since interrupt mode doesn't work.  For
  polled mode during boot, if the status appears to be already complete
  before beginning the check loop, it waits 10 us before actually checking
  the status, just in case the EC is really slow and hasn't gotten to work
  on the new request yet.
- Use upper-case hex for the _Qxx method
- Use device_printf for errors, don't hide them under verbose
- Increase default total timeout to 750 ms and decrease polling interval
  to 5 us.
- Don't pass the status value via the softc.  Just read it directly.
- Remove the mutex. We use the sx lock for transaction serialization
  with the query handler.
- Remove the Intel copyright notice as no code of theirs was ever
  present in this file (verified against rev 1.1)
- Allow KTR module-only builds for ease of testing

other changes too).

(without any real order)

1. Use device_get_nameunit for mutex naming
2. Add timer for low-latency playback
3. Move most mixer controls from sysctls to mixer(8) controls.
   This is a largest part of this patch.
4. Add analog/digital switch (as a temporary sysctl)
5. Get back support for low-bitrate playback (with help of (2))
6. Change locking for exclusive I/O. Writing to non-PTR register
   is almost safe and does not need to be ordered with PTR operations.
7. Disable MIDI until we get it to detach properly and fix memory
   managment problems.
8. Enable multichannel playback by default. It is as stable as
   single-channel mode. Multichannel recording is still an
   experimental feature.
9. Multichannel options can be changed by loader tunables.
10. Add a way to disable card from a loader tunable.
11. Add new PCI IDs.
12. Debugger settings are loader tunables now.
14. Remove some unused variables.
15. Mark pcm sub-devices MPSAFE.

f9ae02802f - Enable static building of mxge(4) and its firmware.
- Add custom .c wrappers for the firmware, rather than the standard
  firmware(9) generated firmware objects to work around toolchain
  problems on ia64 involving linking objects produced by
  ld -b -binary into the kernel.

- Move from using Myricom's ".dat" firmware blobs to using Myricom's
  zlib compressed ".h" firmware header files.  This is done to
  facilitate the custom wrappers, and saves a fair amount of wired
  memory in the case where the firmware is built in, or preloaded.

- Fix two compile issues in mxge which only appear on non-i386/amd64.

fd3ddbd038 Neterion Xframe 10GbE Server/Storage adapter driver.
The nxge driver provides support for Neterion Xframe-I and Xframe-II
adapters. The driver supports TCP Segmentation Offload (TSO/LSO),
Jumbo frames (5 buffer mode), Header separation (2 and 3 Receive
buffer modes), VLAN, and Promiscuous mode.

9b258fca27 MFp4:
- Remove unnecessary NULL checks after M_WAITOK allocations.
 - Use VOP_ACCESS instead of hand-rolled suser_cred()
   calls. [1]
 - Use malloc(9) KPI to allocate memory for string.  The
   optimization taken from NetBSD is not valid for FreeBSD
   because our malloc(9) already act that way. [2]

41621cb408 The viapm module build had what appear to be some debugging CFLAGS left
around to force the IO port to a fixed address.  They were only turned
on in the module build and were present since the original import.  This
breaks soft power-off on the Asus A7V since it reprograms the SMBus base
address to a different one than the BIOS expects.  A similar issue was
found in the alpm(4) module build.

1f5d755661 Use .CURDIR when referring source code. This fixes build
when 'make obj' was done first.  I found this when fixing
a problem reported by tinderbox, but forgot to send the

d1fa59e9e1 MFp4: Add tmpfs, an efficient memory file system.
Please note that, this is currently considered as an
experimental feature so there could be some rough
edges.  Consult http://wiki.freebsd.org/TMPFS for
more information.

For now, connect tmpfs to build on i386 and amd64
architectures only.  Please let us know if you have
success with other platforms.

This work was developed by Julio M. Merino Vidal
for NetBSD as a SoC project; Rohit Jalan ported it
from NetBSD to FreeBSD.  Howard Su and Glen Leeder
are worked on it to continue this effort.

68e8e04e93 Update 802.11 wireless support:
o major overhaul of the way channels are handled: channels are now
  fully enumerated and uniquely identify the operating characteristics;
  these changes are visible to user applications which require changes
o make scanning support independent of the state machine to enable
  background scanning and roaming
o move scanning support into loadable modules based on the operating
  mode to enable different policies and reduce the memory footprint
  on systems w/ constrained resources
o add background scanning in station mode (no support for adhoc/ibss
  mode yet)
o significantly speedup sta mode scanning with a variety of techniques
o add roaming support when background scanning is supported; for now
  we use a simple algorithm to trigger a roam: we threshold the rssi
  and tx rate, if either drops too low we try to roam to a new ap
o add tx fragmentation support
o add first cut at 802.11n support: this code works with forthcoming
  drivers but is incomplete; it's included now to establish a baseline
  for other drivers to be developed and for user applications
o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates
  prepending mbufs for traffic generated locally
o add support for Atheros protocol extensions; mainly the fast frames
  encapsulation (note this can be used with any card that can tx+rx
  large frames correctly)
o add sta support for ap's that beacon both WPA1+2 support
o change all data types from bsd-style to posix-style
o propagate noise floor data from drivers to net80211 and on to user apps
o correct various issues in the sta mode state machine related to handling
  authentication and association failures
o enable the addition of sta mode power save support for drivers that need
  net80211 support (not in this commit)
o remove old WI compatibility ioctls (wicontrol is officially dead)
o change the data structures returned for get sta info and get scan
  results so future additions will not break user apps
o fixed tx rate is now maintained internally as an ieee rate and not an
  index into the rate set; this needs to be extended to deal with
  multi-mode operation
o add extended channel specifications to radiotap to enable 11n sniffing

Drivers:
o ath: add support for bg scanning, tx fragmentation, fast frames,
       dynamic turbo (lightly tested), 11n (sniffing only and needs
       new hal)
o awi: compile tested only
o ndis: lightly tested
o ipw: lightly tested
o iwi: add support for bg scanning (well tested but may have some
       rough edges)
o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data
o wi: lightly tested

This work is based on contributions by Atheros, kmacy, sephe, thompsa,
mlaier, kevlo, and others.  Much of the scanning work was supported by
Atheros.  The 11n work was supported by Marvell.
