c909243f40 Only increment the ypcnt once per data record. The old implementation
was incrementing it twice making it impossible to iterate the table
since the records were 1, 3, 5, 7 (or 2, 4, 6, 8 for the v3 records).

7c9d9e417a Update to version 9.6-ESV-R4-P3
ALL BIND USERS ARE ENCOURAGED TO UPGRADE IMMEDIATELY

This update addresses the following vulnerability:

CVE-2011-2464
=============
Severity:	High
Exploitable:	Remotely

Description:

A defect in the affected BIND 9 versions allows an attacker to remotely
cause the "named" process to exit using a specially crafted packet. This
defect affects both recursive and authoritative servers. The code location
of the defect makes it impossible to protect BIND using ACLs configured
within named.conf or by disabling any features at compile-time or run-time.

410cde006a Remove the IDR_CHEETAH_MAX_BN_PAIRS limit from cheetah_ipi_selected().
This is just a simple approach. For reasons unknown OpenSolaris uses a
more sophisticated one involving IPIing the remaining CPUs in reverse
order after the first batch of 32.

I think the benefit of making the code cleaner and easier to understand

  - Support for IPv6 is added.
  - Request and response now use same struct. Structure specifies
    version (6 or 4), index of last retrieved hash, and also index
    of last retrieved entry in the hash entry.

9acdfe6549 Rework _fget to accept capability parameters.
This new version of _fget() requires new parameters:
- cap_rights_t needrights
    the rights that we expect the capability's rights mask to include
    (e.g. CAP_READ if we are going to read from the file)

- cap_rights_t *haverights
    used to return the capability's rights mask (ignored if NULL)

- u_char *maxprotp
    the maximum mmap() rights (e.g. VM_PROT_READ) that can be permitted
    (only used if we are going to mmap the file; ignored if NULL)

- int fget_flags
    FGET_GETCAP if we want to return the capability itself, rather than
    the underlying object which it wraps

98a7b279a2 The algorithm used by nfscl_getopen() could have resulted in
multiple instances of the same lock_owner when a process both
inherited an open file descriptor plus opened the same file itself.
Since some NFSv4 servers cannot handle multiple instances of
the same lock_owner string, this patch changes the algorithm
used by nfscl_getopen() in the new NFSv4 client to keep that
from happening. The new algorithm is simpler, since there is
no longer any need to ascend the process's parentage tree because
all NFSv4 Closes for a file are done at VOP_INACTIVE()/VOP_RECLAIM(),
making the Opens indistinct w.r.t. use with Lock Ops.
This problem was discovered at the recent NFSv4 interoperability
Bakeathon.

af098ed8e7 Add kernel functions to unwrap capabilities.
cap_funwrap() and cap_funwrap_mmap() unwrap capabilities, exposing the
underlying object. Attempting to unwrap a capability with an inadequate
rights mask (e.g. calling cap_funwrap(fp, CAP_WRITE | CAP_MMAP, &result)
on a capability whose rights mask is CAP_READ | CAP_MMAP) will result in
ENOTCAPABLE.

Unwrapping a non-capability is effectively a no-op.

These functions will be used by Capsicum-aware versions of _fget(), etc.

4bfe7f25f8 With retirement of cpumask_t and usage of cpuset_t for representing a
mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.

Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).

This change is not targeted for MFC because of struct pcpu members
removal and dependency by cpumask_t retirement.
