f510e1c2ec Originally BSD return EINVAL for l_len < 0, but now POSIX wants it too, 
so implement POSIX l_len < 0 handling.

6c3f4fef64 Even better move: suppose that server is able to handle SEEK_END, 
so check arguments for all but not SEEK_END case, leaving SEEK_END
handling for server

e018907ed4 Apparently SEEK_END locking not supported by NFS. Previous variant 
returns EINVAL in that case, change it to EOPNOTSUPP.

4132a3b206 the feederchain builder is currently broken for recording channels. disable 
it until it is fixed.  this limits recording to native formats and speeds
only.

ioctls better- if 0 is passed, return the current setting.  if 1 or 2 are
passed, behave accordingly.  treat values >2 as 2.

67b1dce3bc many changes: 
* add new channels to the end of the list so channels used in order of
addition

* de-globalise definition of struct snddev_info and provide accessor
functions where necessary.

* move the $FreeBSD$ tag in each .c file into a macro and allow the
/dev/sndstat handler to display these when set to maximum verbosity to aid
debugging.

* allow each device to register its own sndstat handler to reduce the amount
of groping sndstat must do in foreign structs.

84031c85e5 Add support for the Netgear MA301 PCI adapter for the MA401. 
It appears that a number of PrismII card vendors seem to be doing the
same thing (that is, using the same PCI bridge chip) to support PCI,
but each with their own vendor/product ID. So rather than cut-n-paste
another if statement into the probe routine, it's probably better to
provide support for a table. Adding new devices will be a lot easier
that way.

sysproto.h in addition to the existing padding afterwards.
This is needed to support big-endian architectures like sparc64.

0cf5e0ebd6 Remove the code that limited the buffer_map to 1/2 the size of the 
kernel_map.  maxbcache takes care of this now and the 1/2 limit can

7dfb550e0c When compressing directory blocks, the dirhash code didn't check 
that the directory entry was in use before attempting to find it
in the hash structures to change its offset. Normally, unused
entries do not need to be moved, but fsck can leave behind some
unused entries that do. A dirhash sanity panic resulted when the
entry to be moved was not found. Add a check that stops entries
with d_ino == 0 from being passed to ufsdirhash_move().

b0e3ad758b Much delayed but now present: RFC 1948 style sequence numbers 
In order to ensure security and functionality, RFC 1948 style
initial sequence number generation has been implemented.  Barring
any major crypographic breakthroughs, this algorithm should be
unbreakable.  In addition, the problems with TIME_WAIT recycling
which affect our currently used algorithm are not present.

3d6fde76ed Introduce two new sysctl's.. vm.kvm_size and vm.kvm_free. These are 
purely informational and can give some advance indications of tuning
problems.  These are i386 only for now as it seems that the i386 is
the only one suffering kvm pressure.

3a9e0f5bd1 Push down Giant some in trap_pfault() so we don't grab Giant around 
trap_fatal() to make restarting from panic's slightly easier.  Before if
one did 'w 0 0' in ddb, the longjmp in ddb inside of trap_fatal() would
result in Giant being held (or recursed one level deeper) which led to
problems later on.  You can now drop to teh debugger, do 'w 0 0', and
continue w/o a problem.
