3871df9ea1 Bump __FreeBSD_version for the removal of IFF_NEEDSGIANT; network
device drivers that require Giant to be held over calls to the ifnet
interface are no longer supported in the FreeBSD 8.x kernel.

e5adda3d51 Remove IFF_NEEDSGIANT, a compatibility infrastructure introduced
in FreeBSD 5.x to allow network device drivers to run with Giant
despite the network stack being Giant-free.  This significantly
simplifies calls into ioctl() on network interfaces, especially
in the multicast code, as well as eliminates deferred invocation
of interface if_start routines.

Disable the build on device drivers still depending on
IFF_NEEDSGIANT as they no longer compile.  They will be removed
in a few weeks if they haven't been made MPSAFE in that time.
Disabled drivers:

        if_ar
        if_axe
        if_aue
        if_cdce
        if_cue
        if_kue
        if_ray
        if_rue
        if_rum
        if_sr
        if_udav
        if_ural
        if_zyd

Drivers that were already disabled because of tty changes:

        if_ppp

ad71fe3c35 Correct a number of evolved problems with inp_vflag and inp_flags:
certain flags that should have been in inp_flags ended up in inp_vflag,
meaning that they were inconsistently locked, and in one case,
interpreted.  Move the following flags from inp_vflag to gaps in the
inp_flags space (and clean up the inp_flags constants to make gaps
more obvious to future takers):

  INP_TIMEWAIT
  INP_SOCKREF
  INP_ONESBCAST
  INP_DROPPED

Some aspects of this change have no effect on kernel ABI at all, as these
are UDP/TCP/IP-internal uses; however, netstat and sockstat detect
INP_TIMEWAIT when listing TCP sockets, so any MFC will need to take this
into account.

1723a06485 - Wrap lock profiling state variables in #ifdef LOCK_PROFILING blocks. 2009-03-15 08:03:54 +00:00
Jeff Roberson
2e6b8de462 - Implement a new mechanism for resetting lock profiling. We now
guarantee that all cpus have acknowledged the cleared enable int by
   scheduling the resetting thread on each cpu in succession.  Since all
   lock profiling happens within a critical section this guarantees that
   all cpus have left lock profiling before we clear the datastructures.
 - Assert that the per-thread queue of locks lock profiling is aware of
   is clear on thread exit.  There were several cases where this was not
   true that slows lock profiling and leaks information.
 - Remove all objects from all lists before clearing any per-cpu
   information in reset.  Lock profiling objects can migrate between
   per-cpu caches and previously these migrated objects could be zero'd
   before they'd been removed

d557a26b80 Generalize the workaround for the Hitachi HT-4840-11. The Contec
C-NET(PC) has a cfe at location 1 that has both an odd irq mask (it
matches pc98 machines, so maybe it was a flag for pc98 operation) as
well as a memory map.  Since this driver doesn't know how to cope, we
start with cfe2, which is purely an I/O space mapped and that seems to
make it work.  I say 'seems' here, because the card I have doesn't
seem to have the right dongle for full testing...

4020272933 Rework MAC Framework synchronization in a number of ways in order to
improve performance:

- Eliminate custom reference count and condition variable to monitor
  threads entering the framework, as this had both significant overhead
  and behaved badly in the face of contention.

- Replace reference count with two locks: an rwlock and an sx lock,
  which will be read-acquired by threads entering the framework
  depending on whether a give policy entry point is permitted to sleep
  or not.

- Replace previous mutex locking of the reference count for exclusive
  access with write acquiring of both the policy list sx and rw locks,
  which occurs only when policies are attached or detached.

- Do a lockless read of the dynamic policy list head before acquiring
  any locks in order to reduce overhead when no dynamic policies are
  loaded; this a race we can afford to lose.

- For every policy entry point invocation, decide whether sleeping is
  permitted, and if not, use a _NOSLEEP() variant of the composition
  macros, which will use the rwlock instead of the sxlock.  In some
  cases, we decide which to use based on allocation flags passed to the
  MAC Framework entry point.

As with the move to rwlocks/rmlocks in pfil, this may trigger witness
warnings, but these should (generally) be false positives as all
acquisition of the locks is for read with two very narrow exceptions
for policy load/unload, and those code blocks should never acquire
other locks.

795dceffa2 Two fixes:
(1) Fix pcib_read/write_config prototypes.
(2) When contrainting a resource request for a 'subtractive' bridge,
    it is important to select a range outside the base/limit
    registers, since those are the only values known to not
    possibly work.  On my HP laptop, the base bridge excludes I/O
    ports 0xa000-0xafff, however that was the range we were passing
    up the tree.  Instead, when a range spans the "hole" we now
    arbitrarily pick the range just above the hole to allocate from.

Pyun YongHyeon
c92b9c8898 bus_dma(9) conversion and make txp(4) work on all architectures.
o Header file cleanup.
o bus_dma(9) conversion.
  - Removed all consumers of vtophys(9) and converted to use
    bus_dma(9).
  - Typhoon2 functional specification says the controller supports
    64bit DMA addressing. However all Typhoon controllers are known
    to lack of DAC support so 64bit DMA support was disabled.
  - The hardware can't handle more 16 fragmented Tx DMA segments so
    teach txp(4) to collapse these segments to be less than 16.
  - Added Rx buffer alignment requirements(4 bytes alignment) and
    implemented fixup code to align receive frame. Previously
    txp(4) always copied Rx frame to align it on 2 byte boundary
    but its copy overhead is much higher than unaligned access on
    i386/amd64. Alignment fixup code is now applied only for
    strict-alignment architectures. With this change i386 and
    amd64 will get instant Rx performance boost. Typhoon2 datasheet
    mentions a command that pads arbitrary bytes in Rx buffer but
    that command does not work.
  - Nuked pointer trick in descriptor ring. This does not work on
    sparc64 and replaced it with bcopy. Alternatively txp(4) can
    embed a 32 bits index value into the descriptor and compute
    real buffer address but it may make code complicated.
  - Added endianness support code in various Tx/Rx/command/response
    descriptor access. With this change txp(4) should work on all
    architectures.
o Added comments for known firmware bugs(Tx checksum offloading,
  TSO, VLAN stripping and Rx buffer padding control).
o Prefer faster memory space register access to I/O space access.
  Added fall-back mechanism to use alternative I/O space access.
  The hardware supports both memory and I/O mapped access. Users
  can still force to use old I/O space access by setting
  hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
o Added experimental suspend/resume methods.
o Nuke error prone Rx buffer handling code and implemented local
  buffer management with TAILQ. Be definition the controller can't
  pass the last received frame to host if no Rx free buffers are
  available to use as head and tail pointer of Rx descriptor ring
  can't have the same value. In that case the Rx buffer pointer in
  Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
  can't fill Rx buffers as the first buffer is still valid. Instead
  of relying on the value of Rx buffer ring, introduce local buffer
  management code to handle empty buffer situation. This should fix
  a long standing bug which completely hangs the controller under
  high network load. I could easily trigger the issue by sending 64
  bytes UDP frames with netperf. I have no idea how this bugs was
  not fixed for a long time.
o Converted ithread interrupt handler to filter based one.
o Rearranged txp_detach routine such that it's now used for general
  clean-up routine.
o Show sleep image version on device attach time. This will help
  to know what action should be taken depending on sleep image
  version. The version information in datasheet was wrong for newer
  NV images so I followed Linux which seems to correctly extract
  version numbers from response descriptors.
o Firmware image is no longer downloaded in device attach time. Now
  it is reloaded whenever if_init is invoked. This is to ensure
  correct operation of hardware when something goes wrong.
  Previously the controller always run without regard to running
  state of firmware. This change will add additional controller
  initialization time but it give more robust operation as txp(4)
  always start off from a known state. The controller is put into
  sleep state until administrator explicitly up the interface.
o As firmware is loaded in if_init handler, it's now possible to
  implement real watchdog timeout handler. When watchdog timer is
  expired, full-reset the controller and initialize the hardware
  again as most other drivers do. While I'm here use our own timer
  for watchdog instead of using if_watchdog/if_timer interface.
o Instead of masking specific interrupts with TXP_IMR register,
  program TXP_IER register with the interrupts to be raised and
  use TXP_IMR to toggle interrupt generation.
o Implemented txp_wait() to wait a specific state of a controller.
o Separate boot related code from txp_download_fw() and name it
  txp_boot() to handle boot process.
o Added bus_barrier(9) to host to ARM communication.
o Added endianness to all typhoon command processing. The ARM93C
  always expects little-endian format of command/data.
o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
  __NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
  Previously __STRICT_ALIGNMENT was unconditionally defined for
  all architectures.
o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
  controlled by ifconfig(8). Note, disabling VLAN hardware tagging
  has no effect due to the bug of firmware.
o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
  txp_tick(). The command is not atomic. Instead, just read the
  statistics and reflect saved statistics to the statistics.
  dev.txp.%d.stats sysctl node provides detailed MAC statistics.
  This also reduces a lot of waste of CPU cycles as processing a
  command ring takes a very long time on ARM93C. Note, Rx
  multicast and broadcast statistics does not seem to right. It
  might be another bug of firmware.
o Implemented link state change handling in txp_tick(). Now sending
  packets is allowed only after establishing a valid link. Also
  invoke link state change notification whenever its state is
  changed so pseudo drivers like lagg(4) that relies on link state
  can work with failover or link aggregation without hacks.
  if_baudrate is updated to resolved speed so SNMP agents can get
  correct bandwidth parameters.
o Overhauled Tx routine such that it now honors number of allowable
  DMA segments and checks for 4 free descriptors before trying to
  send a frame. A frame may require  4 descriptors(1 frame
  descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
  one free descriptor to prevent descriptor wrap-around) at least
  so it's necessary to check available free descriptors prior to
  setting up DMA operation.
o Added a sysctl variable dev.txp.%d.process_limit to control
  how many received frames should be served in Rx handler. Valid
  ranges are 16 to 128(default 64) in unit of frames.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
  calculation as well as VLAN tag insertion/stripping.
o Fixed media header length for VLAN.
o Don't set if_mtu in device attach, it's already set in
  ether_ifattach().
o Enabled MWI.
o Fixed module unload panic when bpf listeners are active.
o Rearranged ethernet address programming logic such that it works
   on strict-alignment architectures.
o Removed unused member variables in softc.
o Added support for WOL.
o Removed now unused TXP_PCI_LOMEM/TXP_PCI_LOIO.
o Added wakeup command TXP_BOOTCMD_WAKEUP definition.
o Added a new firmware version query command, TXP_CMD_READ_VERSION.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
  take care of this.
o Removed embedded union trick of a structure used to to access
  a pointer on LP64 systems.
o Added a few TSO related definitions for struct txp_tcpseg_desc.
  However TSO is not used at all due to the limitation of hardware.
o Redefined PKT_MAX_PKTLEN to theoretical maximum size of a frame.
o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
o Added a new macro TXP_DESC_INC to compute next descriptor index.

ae81968fd1 When writing out updated pollfd records when returning from
poll(), only copy out the revents field, not the whole pollfd
structure.  Otherwise, if the events field is updated
concurrently by another thread, that update may be lost.

This issue apparently causes problems for the JDK on FreeBSD,
which expects the Linux behavior of not updating all fields
(somewhat oddly, Solaris does not implement the required
behavior, but presumably our adaptation of the JDK is based
on the Linux port?).

33fc362512 Add a new internal mount flag (MNTK_EXTENDED_SHARED) to indicate that a
filesystem supports additional operations using shared vnode locks.
Currently this is used to enable shared locks for open() and close() of
read-only file descriptors.
- When an ISOPEN namei() request is performed with LOCKSHARED, use a
  shared vnode lock for the leaf vnode only if the mount point has the
  extended shared flag set.
- Set LOCKSHARED in vn_open_cred() for requests that specify O_RDONLY but
  not O_CREAT.
- Use a shared vnode lock around VOP_CLOSE() if the file was opened with
  O_RDONLY and the mountpoint has the extended shared flag set.
- Adjust md(4) to upgrade the vnode lock on the vnode it gets back from
  vn_open() since it now may only have a shared vnode lock.
- Don't enable shared vnode locks on FIFO vnodes in ZFS and UFS since
  FIFO's require exclusive vnode locks for their open() and close()
  routines.  (My recent MPSAFE patches for UDF and cd9660 already included
  this change.)
- Enable extended shared operations on UFS, cd9660, and UDF.

630b9bf23f Make a 1:1 mapping between syscons stats and terminal emulators.
After I imported libteken into the source tree, I noticed syscons didn't
store the cursor position inside the terminal emulator, but inside the
virtual terminal stat. This is not very useful, because when you
implement more complex forms of line wrapping, you need to keep track of
more state than just the cursor position.

Because the kernel messages didn't share the same terminal emulator as
ttyv0, this caused a lot of strange things, like kernel messages being
misplaced and a missing notification to resize the terminal emulator for
kernel messages never to be resized when using vidcontrol.

This patch just removes kernel_console_ts and adds a special parameter
to te_puts to determine whether messages should be printed using regular
colors or the ones for kernel messages.

5bd65606f4 Adjust some variables (mostly related to the buffer cache) that hold
address space sizes to be longs instead of ints.  Specifically, the follow
values are now longs: runningbufspace, bufspace, maxbufspace,
bufmallocspace, maxbufmallocspace, lobufspace, hibufspace, lorunningspace,
hirunningspace, maxswzone, maxbcache, and maxpipekva.  Previously, a
relatively small number (~ 44000) of buffers set in kern.nbuf would result
in integer overflows resulting either in hangs or bogus values of
hidirtybuffers and lodirtybuffers.  Now one has to overflow a long to see
such problems.  There was a check for a nbuf setting that would cause
overflows in the auto-tuning of nbuf.  I've changed it to always check and
cap nbuf but warn if a user-supplied tunable would cause overflow.

Note that this changes the ABI of several sysctls that are used by things
like top(1), etc., so any MFC would probably require a some gross shims
to allow for that.

d10910e6ce Merge IGMPv3 and Source-Specific Multicast (SSM) to the FreeBSD
IPv4 stack.

Diffs are minimized against p4.
PCS has been used for some protocol verification, more widespread
testing of recorded sources in Group-and-Source queries is needed.
sizeof(struct igmpstat) has changed.

__FreeBSD_version is bumped to 800070.

49e81dc952 - Make it possible to disable GPT support by setting LOADER_NO_GPT_SUPPORT
in make.conf or src.conf.
- When GPT is enabled (which it is by default), use memory above 1 MB and
  leave the memory from the end of the bss to the end of the 640k window
  purely for the stack.  The loader has grown and now it is much more
  common for the heap and stack to grow into each other when both are
  located in the 640k window.

2a7e13e5ad Fix a long-standing bug in newbus. It was introduced when subclassing
was introduced.  If you have a bus, say cardbus, that is derived from
a base-bus (say PCI), then ordinarily all PCI drivers would attach to
cardbus devices.  However, there had been one exception: kldload
wouldn't work.

The problem is in devclass_add_driver.  In this routine, all we did
was call to the pci device's BUS_DRIVER_ADDED routine.  However, since
cardbus bus instances had a different devclass, none of them were
called.

The solution is to call all subclass devclasses, recursively down the
tree, of the class that was loaded.  Since we don't have a 'children
class' pointer, we search the whole list of devclasses for a class
whose parent matches.  Since just done a kldload time, this isn't as
bad as it sounds.  In addition, we short-circuit the whole process by
marking those classes with subclasses with a flag.  We'll likely have
to reevaluate this method the number of devclasses with subclasses
gets large.

This means we can remove the "cardbus" lines from all the PCI drivers
since we have no cardbus specific attach device attachments in the
tree.

ffe96ceede Use a u_int for p_lock instead of a char: this avoids a (somewhat
unlikely but not impossible given modern thread counts) wrap-around,
and the compiler was padding it out to an int (at least) anyway.

b3f468e253 Add a new thread-private flag, TDP_AUDITREC, to indicate whether or
not there is an audit record hung off of td_ar on the current thread.
Test this flag instead of td_ar when auditing syscall arguments or
checking for an audit record to commit on syscall return.  Under
these circumstances, td_pflags is much more likely to be in the cache
(especially if there is no auditing of the current system call), so
this should help reduce cache misses in the system call return path.

get default next page configuration. While I'm here explicitly set
IP1000PHY_ANAR_CSMA bit. This bit is read-only and always set
by hardware so setting it has no effect but it would clear the
intention. With this change controllers that couldn't establish
1000baseT link should work.
