55b4ff0d9f Increase mnt_noasync once in softdep_mount() to disallow async io,
closing a window where a file system using softupdates could be async
for a short while if both MNT_UPDATE and MNT_ASYNC were passed as flags
to nmount().  Add MNTK_SOFTDEP flag to ensure that softdep_mount()
doesn't increase mnt_noasync multiple times.

a1e363f256 Add mnt_noasync counter to better handle interleaved calls to nmount(),
sync() and sync_fsync() without losing MNT_ASYNC.  Add MNTK_ASYNC flag
which is set only when MNT_ASYNC is set and mnt_noasync is zero, and
check that flag instead of MNT_ASYNC before initiating async io.

cea9d840d8 Don't restore mnt_kern_flag on failed MNT_UPDATE mount, it can race
with dounmount(), causing loss of MNTK_UNMOUNT flag.

5da56ddb21 Use mount interlock to protect all changes to mnt_flag and mnt_kern_flag.
This eliminates a race where MNT_UPDATE flag could be lost when nmount()
raced against sync(), sync_fsync() or quotactl().

ebe609b4a2 It is possible for bpf to return a length such that:
length != BPF_WORDALIGN(length)

This meeans that it is possible for this to be true:

	interface->rbuf_offset > interface->rbuf_len

Handle this case in the test for running out of packets.  While
OpenBSD's solution of setting interface->rbuf_len to
BPF_WORDALIGN(length) is safe due to the size of the buffer, I think
this solution results in less hidden assumptions.

This should fix the problem of dhclient running away and consuming 100%
CPU.

the VRRPv2 advertisements will originate from the wrong source address.
This only affects kernels compiled with MROUTING and after the MRT_INIT
ioctl() has been issued.
Set imo_multicast_vif in carp's softc to the invalid value -1 after it is
zeroed by softc allocation, to stop the ip_output() path looking up the
incorrect source address thinking a vif is set.

4bd0c025f3 Vendor import TrustedBSD OpenBSM 1.0 alpha 12, with the following change
history notes since the last import:

OpenBSM 1.0 alpha 12

- Correct bug in auditreduce which prevented the -c option from working
  correctly when the user specifies to process successful or failed events.
  The problem stemmed from not having access to the return token at the time
  the initial preselection occurred, but now a second preselection process
  occurs while processing the return token.
- getacfilesz(3) API added to read new audit_control(5) filesz setting,
  which auditd(8) now sets the kernel audit trail rotation size to.
- auditreduce(1) now uses stdin if no file names are specified on the command
  line; this was the documented behavior previously, but it was not
  implemented.  Be more specific in auditreduce(1)'s examples section about
  what might be done with the output of auditreduce.
- Add audit_warn(5) closefile event so that administrators can hook
  termination of an audit trail file.  For example, this might be used to
  compress the trail file after it is closed.
- auditreduce(1) now uses regular expressions for pathname matching. Users can
  now supply one or more (comma delimited) regular expressions for searching
  the pathnames. If one of the regular expressions is prefixed with a tilde
  (~), and a path matches, it will be excluded from the search results.

9b2b93002d Sleep for one second after calling audit -t to give the audit daemon a
chance to actually terminate the audit service and exit.  Otherwise, on
an rc.d/auditd restart, the new audit daemon instance may try to start
auditing while the previous session is still running.  Likewise, this
ensures a chance for auditd to terminate the audit trail at system
shutdown.

Perhaps more ideally, the script would wait synchronously for auditd to
exit rather than for an arbitrary but short period of time.

22b7bca620 Rework the way errors are handled with respect to how audit records are
written to the audit trail file:

- audit_record_write() now returns void, and all file system specific
  error handling occurs inside this function.  This pushes error handling
  complexity out of the record demux routine that hands off to both the
  trail and audit pipes, and makes trail behavior more consistent with
  pipes as a record destination.

- Rate limit kernel printfs associated with running low on space.  Rate
  limit audit triggers for low space.  Rate limit printfs for fail stop
  events.  Rate limit audit worker write error printfs.

- Document in detail the types of limits and space checks we perform, and
  combine common cases.

This improves the audit subsystems tolerance to low space conditions by
avoiding toasting the console with printfs are waking up the audit daemon
continuously.

b611c801f0 MFp4 the sound Google Summer of Code project:
The goal was to sync with the OSSv4 API 4Front Technologies uses in their
proprietary OSS driver. This was successful as far as possible. The part
of the API which is stable is implemented, for the rest there are some
stubs already.

New system ioctls:
 - SNDCTL_SYSINFO - obtain audio system info (version, # of audio/midi/
   mixer devices, etc.)
 - SNDCTL_AUDIOINFO - fetch details about a specific audio device
 - SNDCTL_MIXERINFO - fetch details about a specific mixer device

New audio ioctls:
 - Sync groups (SNDCTL_DSP_SYNCGROUP/SNDCTL_DSP_SYNCSTART) which allow
   triggered playback/recording on multiple devices (even across processes
   simultaneously).
 - Peak meters (SNDCTL_DSP_GETIPEAKS/SNDCTL_DSP_GETOPEAKS) - can query
   audio drivers for peak levels (needs driver support, disabled for now).
 - Per channel playback/recording levels -
   SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL.  Note that these are still in name
   only, just wrapping around the AC97-style mixer at the moment. The next
   step is to push them down to the drivers.

Audio ioctls still under development by 4Front (for which stubs may exist
in this commit):
 - SNDCTL_GETNAME, SNDCTL_{GET,SET}{SONG,LABEL}
 - SNDCTL_DSP_{GET,SET}_CHNORDER
 - SNDCTL_MIX_ENUMINFO, SNDCTL_MIX_EXTINFO - (might be documented enough in
   the OSS releases to work on this.  These ioctls cover the cool "twiddle
   any knob on your card" features.)

Missing:
 - SNDCTL_DSP_COOKEDMODE -- this ioctl is used to give applications direct
   access to a card's buffers, bypassing the feeder architecture.  It's
   a toughy -- "someone" needs to decide :
   (a) if this is desireable, and (b) if it's reasonably feasible.

Updates for driver writers:
 So far, only two routines to the channel class (in channel_if.m) are added.
 One is for fetching a list of discrete supported playback/recording rates
 of a channel, and the other is for fetching peak level info (useful for
 drawing peak meters).  Interested parties may want to help pushing down
 SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL into the drivers.

To use the new stuff you need to rebuild the sound drivers or your kernel
(depending on if you use modules or not) and to install soundcard.h (a
buildworld/installworld handles this).
