63f89abf4a Change the generated VOP_ macro implementations to improve type checking
and KASSERT coverage.

After this check there is only one "nasty" cast in this code but there
is a KASSERT to protect against the wrong argument structure behind
that cast.

Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical
kernel with no change in performance.

We also now run the checking and tracing on VOP's which have been layered
by nullfs, umapfs, deadfs or unionfs.

    Add new (non-inline) VOP_FOO_AP() functions which take a "struct
    foo_args" argument and does everything the VOP_FOO() macros
    used to do with checks and debugging code.

    Add KASSERT to VOP_FOO_AP() check for argument type being
    correct.

    Slim down VOP_FOO() inline functions to just stuff arguments
    into the struct foo_args and call VOP_FOO_AP().

    Put function pointer to VOP_FOO_AP() into vop_foo_desc structure
    and make VCALL() use it instead of the current offsetoff() hack.

    Retire vcall() which implemented the offsetoff()

    Make deadfs and unionfs use VOP_FOO_AP() calls instead of
    VCALL(), we know which specific call we want already.

    Remove unneeded arguments to VCALL() in nullfs and umapfs bypass
    functions.

    Remove unused vdesc_offset and VOFFSET().

    Generally improve style/readability of the generated code.

d1426d7fc5 Locking and cleanup of tty netgraph node. Tty stack is Giant-locked,
so we need to acquire Giant in netgraph methods, so that we don't
race with line discipline methods. Remove NET_NEEDS_GIANT.

- Packets coming into node from netgraph are queued in ifqueue
  attached to node private data.
- Mutex in struct ifqueue is used to lock not only the queue, but
  the whole private data, and tp->t_lsc field.
- tp->t_lsc pointer is used to indicate whether line discipline is
  attached to netgraph or not.
- Use FLG_DIE flag to indicate that node may be destroyed.
  (This protection doesn't work, and it didn't before. Must be redesigned.)
- Increment ngt_unit atomically, removing mutex.
- Acquire Giant, when executing ngt_start() from netgraph context.
- Acquire Giant, when {,de}registering line discipline.
- Uncomment forcing queue mode on peers hook, since this is reasonable.
- Force queue mode on our hook, to avoid acquiring Giant when coming from
  network stack. We may already hold some mutexes at this point.

Cleanups:
- Use callout_pending() instead of our own flag.
- Remove spl(9) calls. Now we can use return() instead of ERROUT().

style(9):
- Sort includes.
- Sparse initializer for struct linesw.
- Remove some empty lines, sort declarations.

739211f027 - allow a device hint to disable probing a slot on a Uninorth PCI bus.
e.g. at the loader:

	set hint.pcib.1.skipslot=26

  This allows undocumented and problematic hardware on some systems
  to be ignored, for instance, the USB keyboard/mouse that shows up
  on a 12" albook that doesn't exist nor do anything other than eat up
  the syscons keyboard. Another one is the unused USB cell in the old
  366MHz iBook that locks up the machine when probed.

  In a way this is temporary, since there are better fixes for the
  above problems, but will be useful in the meantime by allowing
  a keyboard to be used to help debug said fixes :)

8df6bac4c7 Remove the unused credential argument from VOP_FSYNC() and VFS_SYNC().
I'm not sure why a credential was added to these in the first place, it is
not used anywhere and it doesn't make much sense:

	The credentials for syncing a file (ability to write to the
	file) should be checked at the system call level.

	Credentials for syncing one or more filesystems ("none")
	should be checked at the system call level as well.

	If the filesystem implementation needs a particular credential
	to carry out the syncing it would logically have to the
	cached mount credential, or a credential cached along with
	any delayed write data.

c5c1b16ec5 While we want the recursion protection for the bucket zones so that
recursion from the VM is handled (and the calling code that allocates
buckets knows how to deal with it), we do not want to prevent allocation
from the slab header zones (slabzone and slabrefzone) if uk_recurse is
not zero for them.  The reason is that it could lead to NULL being
returned for the slab header allocations even in the M_WAITOK
case, and the caller can't handle that (this is also explained in a
comment with this commit).

The problem analysis is documented in our mailing lists:
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=153445+0+archive/2004/freebsd-current/20041231.freebsd-current

980b8b89eb Make default RFCOMM session MTU match default L2CAP MTU.
This is just a workaround for a know problem with Motorola E1000
phone. Something is wrong with the configuration of L2CAP/RFCOMM
channel. Even though we set L2CAP MTU to 132 bytes (default RFCOMM
MTU 127 + 5 bytes RFCOMM frame header) and the phone accepts it,
the phone still sends oversized L2CAP packets. It appears that the
phone wants to use bigger (667 bytes) RFCOMM frames, but it does
not segment them according to the configured L2CAP MTU. The 667
bytes RFCOMM frame size corresponds to the default L2CAP MTU of
672 bytes (667 + 5 bytes RFCOMM frame header).

This problem only appears if connection was initiated from the
phone. I'm not sure who is at fault here, so for now just put
workaround in place. Quick look at the spec did not reveal any
anwser.

e926c0ae48 Recent changes have locked down most of the highly dynamic data
structures in IPX/SPX -- primarily, sequence numbering, PCB lists,
and PCBs for IPX raw sockets, IPX datagram sockets, and IPX/SPX.
As such, remove remove NET_NEEDS_GIANT() for IPX, and remove the
assertion of Giant in the ipxintr() IPX input path.

Note that IPX/SPX is not fully MPSAFE, and that there are some
problems with IPX/SPX locking that will require some further work.
However, it is now safe enough to run in general without the Giant
lock.

2082ca5d57 Use the IPX PCB list mutex and IPX PCB mutexes to lock down the SPX
portion of IPX/SPX:

- Protect IPX PCB lists with the IPX PCB list mutex, in particular
  when calling PCB and PCB list manipulation routines in ipx_pcb.c.
- Protect both IPX PCB state and SPX PCB state using the IPX PCB
  mutex.
- Generally annotate locking, as well as adding liberal use of lock
  assertions to document locking requirements.
- Where possible, use unlocked reads when reading integer or smaller
  sized socket options on SPX sockets.
- De-spl throughout.

Notes:

- spx_input() expects both the list mutex and PCB mutex to be held
  on entry, but will release both on return.  Because sonewconn() is
  called from spx_input(), it may actually drop one PCB lock and
  acquire another during generation of a new connection, meaning the
  caller is not in a position to unlock the PCB mutex.

2375a5a16a Clean up return handling for a number of SPX-related routines that
were derived from more complex TCP versions of the same:

- spx_close(), spx_disconnect(), spx_drop(), and spx_usrclosed() all
  always free's the spxpcb invalidating the argument, so a return
  value is not required to indicate if it has.
- Annotate that the cb arguments to each of these functions is
  invalidated via a comment.
- When tearing down a pcb due to sonewconn() having failed, mark the
  cb as NULL; later, when deciding whether to store trace information
  due to SO_DEBUG, check that cb is not NULL before dereferencing or
  a NULL pointer dereference may occur.

dd08fca3b6 Fix support for machines with default MP Table configurations:
- Fix the MP Table pci bridge drivers to not probe the configuration table
  unless we actually have one.  Machines using a default configuration do
  not have such a table.
- Only allow default configuration types of 5 (ISA + PCI) and 6 (EISA +
  PCI) as the others are not likely to work.  Types 1 through 4 use an
  external APIC (probably with 80486 processors) which we certainly do not
  support, and type 7 uses an MCA bus which has not been tested with the
  new MP Table code.
- Correct the fact that the single I/O APIC in a default configuration has
  an ID of 2, not 0.
- Fix off by one errors in setting the bus types from the default_data[]
  arrays for default configurations.
- Explicitly configure each of the 16 interrupt pins on the sole I/O APIC
  when using a default configuration.  This is especially helpful for type
  6 (EISA + PCI) since the EISA interrupts need to have their polarity
  programmed based on the values in the ELCR.

Much thanks to the submitter and tester who endured several rounds of
testing to get this fixed.

33fb8a386e Rework the optimization for spinlocks on UP to be slightly less drastic and
turn it back on.  Specifically, the actual changes are now less intrusive
in that the _get_spin_lock() and _rel_spin_lock() macros now have their
contents changed for UP vs SMP kernels which centralizes the changes.
Also, UP kernels do not use _mtx_lock_spin() and no longer include it.  The
UP versions of the spin lock functions do not use any atomic operations,
but simple compares and stores which allow mtx_owned() to still work for
spin locks while removing the overhead of atomic operations.

328b4b876f Disable checksum offloading by default. It seems to produce corrupted packets
with some revisions of the chip (particularly when using multiple TX
descriptors).

32a300364d Forget about the sis_list_data and sis_ring_data structures and embedd
their fields directly in the softc structure.

This is a no-op which shortens most of the affected source lines
by N * 10 characters.

778ee7be10 Allow fxp(4) cards with a revision id of 0 to use the 82503 serial
interface as well.  This is not an expected revision id per the
datasheet, but unfortunately there are such cards out there with
a 82557 chipset, and they want to use the 82503.
