9c4d63da6d o Make the credential used by socreate() an explicit argument to
socreate(), rather than getting it implicitly from the thread
  argument.

o Make NFS cache the credential provided at mount-time, and use
  the cached credential (nfsmount->nm_cred) when making calls to
  socreate() on initially connecting, or reconnecting the socket.

This fixes bugs involving NFS over TCP and ipfw uid/gid rules, as well
as bugs involving NFS and mandatory access control implementations.

23b590188f Fix a BUF_TIMELOCK race against BUF_LOCK and fix a deadlock in vget()
against VM_WAIT in the pageout code.  Both fixes involve adjusting
the lockmgr's timeout capability so locks obtained with timeouts do not
interfere with locks obtained without a timeout.

Hopefully MFC: before the 4.5 release

08f3c74981 Pseudofs was leaking VFS cache entries badly due to its cache and use of
the wrong VOP descriptor.  This misuse caused VFS-cached vnodes to be
re-cached, resulting in the leak.  This commit is an interim fix until DES
has a chance to rework the code involved.

53f09e7248 Add module dependency on libmchain.
With this change, mounting an smb share (using mount_smb, which is not
yet included in the tree) without any of smbfs, libiconv or libmchain
compiled into the kernel or loaded works.

011376308f o Introduce pr_mtx into struct prison, providing protection for the
mutable contents of struct prison (hostname, securelevel, refcount,
  pr_linux, ...)
o Generally introduce mtx_lock()/mtx_unlock() calls throughout kern/
  so as to enforce these protections, in particular, in kern_mib.c
  protection sysctl access to the hostname and securelevel, as well as
  kern_prot.c access to the securelevel for access control purposes.
o Rewrite linux emulator abstractions for accessing per-jail linux
  mib entries (osname, osrelease, osversion) so that they don't return
  a pointer to the text in the struct linux_prison, rather, a copy
  to an array passed into the calls.  Likewise, update linprocfs to
  use these primitives.
o Update in_pcb.c to always use prison_getip() rather than directly
  accessing struct prison.

94a0557ad7 Fix mounting root from a ISO9660 filesystem on a SCSI CDROM.
The problem was that the ISO9660 code wasn't opening the device prior to
issuing ioctl calls.  In particular, the device must be open before
iso_get_ssector() is called in iso_mountroot().

If the device isn't opened first, the disk layer blows up due to an
uninitialized variable.

The solution was to open the device, call iso_get_ssector() and then close
it again.

The ATAPI CDROM driver doesn't have this problem because it doesn't use the
disk layer, and evidently doesn't mind if someone issues an ioctl without
first issuing an open call.

Thanks to phk for pointing me at the source of this problem.

(of struct stat) for directories as appropriate.  Note that st_size is
always set to DEV_BSIZE, since the size of the directories is not

Basically FIFOs become a real pain to abuse as a rendevous point without

return ready even though there is no writer (to signal EOF).

6b8bd2efc1 Add mnt_reservedvnlist so we can MFC to 4.x, in order to make all mount
structure changes now rather then piecemeal later on.  mnt_nvnodelist
currently holds all the vnodes under the mount point.  This will eventually
be split into a 'dirty' and 'clean' list.  This way we only break kld's once
rather then twice.  nvnodelist will eventually turn into the dirty list
and should remain compatible with the klds.

aa454a4b53 Fix a bug in CD9660 when vmiodirenable is turned on. CD9660 was assuming
that a buffer's b_blkno would be valid.  This is true when vmiodirenable
is turned off because the B_MALLOC'd buffer's data is invalidated when
the buffer is destroyed.  But when vmiodirenable is turned on a buffer
can be reconstituted from its VMIO backing store.  The reconstituted buffer
will have no knowledge of the physical block translation and the result is
serious directory corruption of the CDROM.

The solution is to fix cd9660_blkatoff() to always BMAP the buffer if
b_lblkno == b_blkno.
