eb73a605cd o add a CRYPTO_F_CBIMM flag to symmetric ops to indicate the callback
should be done in crypto_done rather than in the callback thread
o use this flag to mark operations from /dev/crypto since the callback
  routine just does a wakeup; this eliminates the last unneeded ctx switch
o change CRYPTO_F_NODELAY to CRYPTO_F_BATCH with an inverted meaning
  so "0" becomes the default/desired setting (needed for user-mode
  compatibility with openbsd)
o change crypto_dispatch to honor CRYPTO_F_BATCH instead of always
  dispatching immediately
o remove uses of CRYPTO_F_NODELAY
o define COP_F_BATCH for ops submitted through /dev/crypto and pass
  this on to the op that is submitted

Similar changes and more eventually coming for asymmetric ops.

MFC if re gives approval.

19d4fb8e5c Workaround for compiling LINT. Large kernels (like LINT) can have
branch targets that are too far apart for the BRADDR relocation.
This is caused by the branch prediction optimizationi in the atomic
inlines here, because they jump across sections.
The workaround is to suppress jumping to a different section when
compiling LINT. To generate correct code in that case, the section
directives are replaced by a branch and a label to deal with the
fall-through case. Reasonably good C compilers will optimize this
away anyway, so the end result isn't really that bad.

14dd6717f8 Add a new config option IPSEC_FILTERGIF to control whether or not
packets coming out of a GIF tunnel are re-processed by ipfw, et. al.
By default they are not reprocessed.  With the option they are.

This reverts 1.214.  Prior to that change packets were not re-processed.
After they were which caused problems because packets do not have
distinguishing characteristics (like a special network if) that allows
them to be filtered specially.

This is really a stopgap measure designed for immediate MFC so that
4.8 has consistent handling to what was in 4.7.

fd18f292bd Make xl use m_getcl() to allocate an mbuf and a cluster in one shot,
as opposed to one after the other.  This is faster in both -CURRENT
and -STABLE.  Additionally, there is less code duplication for
error-checking.

One thing to note is that this code seems to return(1) when no buffers
are available; perhaps ENOBUFS should be the correct return value?

5bb651cb72 This patch fixes a deadlock between the bufdaemon and a process taking
a snapshot. As part of taking a snapshot of a filesystem, the kernel
builds up a list of the filesystem metadata (such as the cylinder
group bitmaps) that are contained in the snapshot. When doing a
copy-on-write check, the list is first consulted. If the block being
written is found on the list, then the full snapshot lookup can be
avoided. Besides providing an important performance speedup this
check also avoids a potential deadlock between the code creating
the snapshot and the bufdaemon trying to cleanup snapshot related
buffers. This fix creates a temporary list containing the key
metadata blocks that can cause the deadlock. This temporary list
is used between the time that the snapshot is first enabled and the
time that the fully complete list is built.

37e2ebfdba This patch fixes a bug on an active filesystem on which a snapshot
is being taken from panicing with either "freeing free block" or
"freeing free inode". The problem arises when the snapshot code
is scanning the filesystem looking for inodes with a reference
count of zero (e.g., unlinked but still open) so that it can
expunge them from its view. If it encounters a reclaimed vnode
and has to restart its scan, then it will panic if it encounters
and tries to free an inode that it has already processed. The fix
is to check each candidate inode to see if it has already been
processed before trying to delete it from the snapshot image.

2c6b49f6af NO_GEOM cleanup:
Retire the "d_dump_t" and use the "dumper_t" type instead.

Dumper_t takes a void * as first arg which is more general than the
dev_t taken by d_dump_t.  (Remember: we could have net-dumpers if
somebody wrote us one!)

Define the convention for GEOM controlled disk devices to be that the
first argument to the dumper function is the struct disk pointer.

56eac725a3 Fix ATAPI/USB/Firewire CDROM drive handling in cd(4) and hopefully fix
a number of related problems along the way.

 - Automatically detect CDROM drives that can't handle 6 byte mode
   sense and mode select, and adjust our command size accordingly.
   We have to handle this in the cd(4) driver (where the buffers are
   allocated), since the parameter list length is different for the
   6 and 10 byte mode sense commands.

 - Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM
   and in the umass(4) driver, since there's no way for that to work
   properly.

 - Add a quirk entry for CDROM drives that just hang when they get a 6
   byte mode sense or mode select.  The reason for the quirk must be
   documented in a PR, and all quirks must be approved by
   ken@FreeBSD.org.  This is to make sure that we fully understand why
   each quirk is needed.  Once the CAM_NEW_TRAN_CODE is finished, we
   should be able to remove any such quirks, since we'll know what
   protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether
   we should use 6 or 10 byte mode sense/select commands.

 - Change the way the da(4) handles the no_6_byte sysctl.  There is
   now a per-drive sysctl to set the minimum command size for that
   particular disk.  (Since you could have multiple disks with
   multiple requirements in one system.)

 - Loader tunable support for all the sysctls in the da(4) and cd(4)
   drivers.

 - Add a CDIOCCLOSE ioctl for cd(4) (bde pointed this out a long
   time ago).

 - Add a media validation routine (cdcheckmedia()) to the cd(4)
   driver, to fix some problems bde pointed out a long time ago.  We
   now allow open() to succeed no matter what, but if we don't detect
   valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT
   ioctls.

 - The media validation routine also reads the table of contents off
   the drive.  We use the table of contents to implement the
   CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command.  The
   PLAY AUDIO TRACK INDEX command that we previously used was
   deprecated after SCSI-2.  It works in every SCSI CDROM I've tried,
   but doesn't seem to work on ATAPI CDROM drives.  We still use the
   play audio track index command if we don't have a valid TOC, but
   I suppose it'll fail anyway in that case.

 - Add _len() versions of scsi_mode_sense() and scsi_mode_select() so
   that we can specify the minimum command length.

 - Fix a couple of formatting problems in the sense printing code.

b0d226932e The ancient and outdated concept of "privileged ports" in UNIX-type
OSes has probably caused more problems than it ever solved. Allow the
user to retire the old behavior by specifying their own privileged
range with,

  net.inet.ip.portrange.reservedhigh  default = IPPORT_RESERVED - 1
  net.inet.ip.portrange.reservedlo    default = 0

Now you can run that webserver without ever needing root at all. Or
just imagine, an ftpd that can really drop privileges, rather than
just set the euid, and still do PORT data transfers from 20/tcp.

Two edge cases to note,

  # sysctl net.inet.ip.portrange.reservedhigh=0

Opens all ports to everyone, and,

  # sysctl net.inet.ip.portrange.reservedhigh=65535

Locks all network activity to root only (which could actually have
been achieved before with ipfw(8), but is somewhat more
complicated).

For those who stick to the old religion that 0-1023 belong to root and
root alone, don't touch the knobs (or even lock them by raising
securelevel(8)), and nothing changes.
