452d9f5b1c Attempt to consistently use () around return values in calls to
return() in newer code (sysctl, ISN, timewait).

06da46b241 Remove an XXXRW comment relating to whether or not the TCP timers are
MPSAFE: they are now believed to be.

950ab1e470 Remove an annotation of a minor race relating to the update of
multiple MIB entries using sysctl in short order, which might
result in unexpected values for tcp_maxidle being generated by
tcp_slowtimo.  In practice, this will not happen, or at least,
doesn't require an explicit comment.

1ef121cf6b In sonewconn(), the s/if/while/ change to wait for room at the tail of
the accept queue is a feature, not a bug/issue, so remove the XXXRW
from the comment.

ba65391172 Remove an XXXRW indicating atomic operations might be used as a
substitute for a global mutex protecting the socket count and
generation number.

The observation that soreceive_rcvoob() can't return an mbuf
chain is a property, not a bug, so remove the XXXRW.

In sorflush, s/existing/previous/ for code when describing prior
behavior.

For SO_LINGER socket option retrieval, remove an XXXRW about why
we hold the mutex: this is correct and not dubious.

81b5dbecd4 In soalloc(), simplify the mac_init_socket() handling to remove
unnecessary use of a global variable and simplify the return case.
While here, use ()'s around return values.

In sodealloc(), remove a comment about why we bump the gencnt and
decrement the socket count separately.  It doesn't add
substantially to the reading, and clutters the function.

9a9f504132 - Add genid field to the metadata which will allow to improve reliability a bit.
After this change, when component is disconnected because of an I/O error,
  it will not be connected and synchronized automatically, it will be logged
  as broken and skipped. Autosynchronization can occur, when component is
  disconnected (on orphan event) and connected again - there were no I/O
  error, so there is no need to not connected the component, but when there were
  writes while it wasn't connected, it will be synchronized.
  This fix cases, when component is disconnected because of I/O error and can be
  connected again and again.
- Bump version number.
- Add version change history.
- Implement backward compatibility mechanism. After this change when metadata in
  old version is detected, it is automatically upgraded to the new (current)
  version.

7abe2ac214 Add send buffer locking to uipc_send(). Without this locking a race can
occur between a reader and a writer that results in a panic upon close,
e.g.,
	"panic: sbflush_locked: cc 4 || mb 0xffffff0052afa400 || mbcnt 0"

50a36c111f Be consistent about flag values passed to device drivers read/write
methods:

Read can see O_NONBLOCK and O_DIRECT.

Write can see O_NONBLOCK, O_DIRECT and O_FSYNC.

In addition O_DIRECT is shadowed as IO_DIRECT for now for backwards
compatibility.

10eee285f7 Shuffle numeric values of the IO_* flags to match the O_* flags from
fcntl.h.

This is in preparation for making the flags passed to device drivers be
consistently from fcntl.h for all entrypoints.

Today open, close and ioctl uses fcntl.h flags, while read and write
uses vnode.h flags.

ead42fc389 Use vtopde() instead of pmap_pde() in pmap_kextract(); vtopde() is smaller

f663832b75 This should not be permitted, but some GEOM classes held the topology lock
while doing g_(read|write)_data() (e.g. BSD). This can cause a deadlock
in MIRROR class. Not sure if this is safe to drop the topology lock in BSD
class, so change the code in MIRROR class to avoid this deadlock.

e1e6b9d3c6 - The IQ80321 has a jumper which changes the PCI device id from 4 to 8 for the
GigE controller, so handle this.
- Use the outbound window 0 if the PCI mem requested is in its range, instead
of inconditionally use the outbound window 1.
This should be enough to get FreeBSD/arm to work on the IQ80321 board as well.

e87047b437 We can only ever get to vgonechrl() from a devfs vnode, so we do not

value already.
