6a288ef517 Update Bind to 9.9.3-P2
Notable new features:

*  Elliptic Curve Digital Signature Algorithm keys and signatures in
   DNSSEC are now supported per RFC 6605. [RT #21918]

*  Introduces a new tool "dnssec-verify" that validates a signed zone,
   checking for the correctness of signatures and NSEC/NSEC3 chains.
   [RT #23673]

*  BIND now recognizes the TLSA resource record type, created to
   support IETF DANE (DNS-based Authentication of Named Entities)
   [RT #28989]

*  The new "inline-signing" option, in combination with the
   "auto-dnssec" option that was introduced in BIND 9.7, allows
   named to sign zones completely transparently.

c7af094e18 Expand the use of stat(2) flags to allow storing some Windows/DOS
and CIFS file attributes as BSD stat(2) flags.

This work is intended to be compatible with ZFS, the Solaris CIFS
server's interaction with ZFS, somewhat compatible with MacOS X,
and of course compatible with Windows.

The Windows attributes that are implemented were chosen based on
the attributes that ZFS already supports.

The summary of the flags is as follows:

UF_SYSTEM:	Command line name: "system" or "usystem"
		ZFS name: XAT_SYSTEM, ZFS_SYSTEM
		Windows: FILE_ATTRIBUTE_SYSTEM

		This flag means that the file is used by the
		operating system.  FreeBSD does not enforce any
		special handling when this flag is set.

UF_SPARSE:	Command line name: "sparse" or "usparse"
		ZFS name: XAT_SPARSE, ZFS_SPARSE
		Windows: FILE_ATTRIBUTE_SPARSE_FILE

		This flag means that the file is sparse.  Although
		ZFS may modify this in some situations, there is
		not generally any special handling for this flag.

UF_OFFLINE:	Command line name: "offline" or "uoffline"
		ZFS name: XAT_OFFLINE, ZFS_OFFLINE
		Windows: FILE_ATTRIBUTE_OFFLINE

		This flag means that the file has been moved to
		offline storage.  FreeBSD does not have any special
		handling for this flag.

UF_REPARSE:	Command line name: "reparse" or "ureparse"
		ZFS name: XAT_REPARSE, ZFS_REPARSE
		Windows: FILE_ATTRIBUTE_REPARSE_POINT

		This flag means that the file is a Windows reparse
		point.  ZFS has special handling code for reparse
		points, but we don't currently have the other
		supporting infrastructure for them.

UF_HIDDEN:	Command line name: "hidden" or "uhidden"
		ZFS name: XAT_HIDDEN, ZFS_HIDDEN
		Windows: FILE_ATTRIBUTE_HIDDEN

		This flag means that the file may be excluded from
		a directory listing if the application honors it.
		FreeBSD has no special handling for this flag.

		The name and bit definition for UF_HIDDEN are
		identical to the definition in MacOS X.

UF_READONLY:	Command line name: "urdonly", "rdonly", "readonly"
		ZFS name: XAT_READONLY, ZFS_READONLY
		Windows: FILE_ATTRIBUTE_READONLY

		This flag means that the file may not written or
		appended, but its attributes may be changed.

		ZFS currently enforces this flag, but Illumos
		developers have discussed disabling enforcement.

		The behavior of this flag is different than MacOS X.
		MacOS X uses UF_IMMUTABLE to represent the DOS
		readonly permission, but that flag has a stronger
		meaning than the semantics of DOS readonly permissions.

UF_ARCHIVE:	Command line name: "uarch", "uarchive"
		ZFS_NAME: XAT_ARCHIVE, ZFS_ARCHIVE
		Windows name: FILE_ATTRIBUTE_ARCHIVE

		The UF_ARCHIVED flag means that the file has changed and
		needs to be archived.  The meaning is same as
		the Windows FILE_ATTRIBUTE_ARCHIVE attribute, and
		the ZFS XAT_ARCHIVE and ZFS_ARCHIVE attribute.

		msdosfs and ZFS have special handling for this flag.
		i.e. they will set it when the file changes.

sys/param.h:		Bump __FreeBSD_version to 1000047 for the
			addition of new stat(2) flags.

chflags.1:		Document the new command line flag names
			(e.g. "system", "hidden") available to the
			user.

ls.1:			Reference chflags(1) for a list of file flags
			and their meanings.

strtofflags.c:		Implement the mapping between the new
			command line flag names and new stat(2)
			flags.

chflags.2:		Document all of the new stat(2) flags, and
			explain the intended behavior in a little
			more detail.  Explain how they map to
			Windows file attributes.

			Different filesystems behave differently
			with respect to flags, so warn the
			application developer to take care when
			using them.

zfs_vnops.c:		Add support for getting and setting the
			UF_ARCHIVE, UF_READONLY, UF_SYSTEM, UF_HIDDEN,
			UF_REPARSE, UF_OFFLINE, and UF_SPARSE flags.

			All of these flags are implemented using
			attributes that ZFS already supports, so
			the on-disk format has not changed.

			ZFS currently doesn't allow setting the
			UF_REPARSE flag, and we don't really have
			the other infrastructure to support reparse
			points.

msdosfs_denode.c,
msdosfs_vnops.c:	Add support for getting and setting
			UF_HIDDEN, UF_SYSTEM and UF_READONLY
			in MSDOSFS.

			It supported SF_ARCHIVED, but this has been
			changed to be UF_ARCHIVE, which has the same
			semantics as the DOS archive attribute instead
			of inverse semantics like SF_ARCHIVED.

			After discussion with Bruce Evans, change
			several things in the msdosfs behavior:

			Use UF_READONLY to indicate whether a file
			is writeable instead of file permissions, but
			don't actually enforce it.

			Refuse to change attributes on the root
			directory, because it is special in FAT
			filesystems, but allow most other attribute
			changes on directories.

			Don't set the archive attribute on a directory
			when its modification time is updated.
			Windows and DOS don't set the archive attribute
			in that scenario, so we are now bug-for-bug
			compatible.

smbfs_node.c,
smbfs_vnops.c:		Add support for UF_HIDDEN, UF_SYSTEM,
			UF_READONLY and UF_ARCHIVE in SMBFS.

			This is similar to changes that Apple has
			made in their version of SMBFS (as of
			smb-583.8, posted on opensource.apple.com),
			but not quite the same.

			We map SMB_FA_READONLY to UF_READONLY,
			because UF_READONLY is intended to match
			the semantics of the DOS readonly flag.
			The MacOS X code maps both UF_IMMUTABLE
			and SF_IMMUTABLE to SMB_FA_READONLY, but
			the immutable flags have stronger meaning
			than the DOS readonly bit.

stat.h:			Add definitions for UF_SYSTEM, UF_SPARSE,
			UF_OFFLINE, UF_REPARSE, UF_ARCHIVE, UF_READONLY
			and UF_HIDDEN.

			The definition of UF_HIDDEN is the same as
			the MacOS X definition.

			Add commented-out definitions of
			UF_COMPRESSED and UF_TRACKED.  They are
			defined in MacOS X (as of 10.8.2), but we
			do not implement them (yet).

ufs_vnops.c:		Add support for getting and setting
			UF_ARCHIVE, UF_HIDDEN, UF_OFFLINE, UF_READONLY,
			UF_REPARSE, UF_SPARSE, and UF_SYSTEM in UFS.
			Alphabetize the flags that are supported.

			These new flags are only stored, UFS does
			not take any action if the flag is set.

fd29e78a68 libc: Access _logname_valid more efficiently.
The variable _logname_valid is not exported via the version script;
therefore, change C and i386/amd64 assembler code to remove indirection
(which allowed interposition). This makes the code slightly smaller and
faster.

Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC,
there is no place containing the address of each variable, so there is no
possible definition for PIC_GOT.

3bfcb89de4 Add new mmap(2) flags to permit applications to request specific virtual
address alignment of mappings.
- MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n).
  Requests for n >= number of bits in a pointer or less than the size of
  a page fail with EINVAL.  This matches the API provided by NetBSD.
- MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED.  It can be used
  to optimize the chances of using large pages.  By default it will align
  the mapping on a large page boundary (the system is free to choose any
  large page size to align to that seems best for the mapping request).
  However, if the object being mapped is already using large pages, then
  it will align the virtual mapping to match the existing large pages in
  the object instead.
- Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and
  VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment.
  MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while
  MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE.
- mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than
  explicitly using VMFS_SUPER_SPACE.  All device objects are forced to
  use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively
  equivalent.

4fb136d770 vfork(2) was listed as deprecated in 1994 (r1573) and was the false
reports of its impending demise were removed in 2009 (r199257).

However, in 1996 (r16117) system(3) was switched from vfork(2) to
fork(2) based partly on this.  Switch back to vfork(2).  This has a
dramatic effect in cases of extreme mmap use - such as excessive
abuse (500+) of shared libraries.

popen(3) has used vfork(2) for a while.  vfork(2) isn't going anywhere.

995e1f0063 The iconv in libc did two things - implement the standard APIs, the GNU
extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.

WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.

I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can.  I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc.  If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.

This is an extension of behavior on other system.  iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.

Bumped osreldate.

ef27886236 Update Bind to 9.8.5-P2
New Features

   Adds a new configuration option, "check-spf"; valid values are
   "warn" (default) and "ignore".  When set to "warn", checks SPF
   and TXT records in spf format, warning if either resource record
   type occurs without a corresponding record of the other resource
   record type.  [RT #33355]

   Adds support for Uniform Resource Identifier (URI) resource
   records. [RT #23386]

   Adds support for the EUI48 and EUI64 RR types. [RT #33082]

   Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
   and L64). [RT #31836]

Feature Changes

   Changes timing of when slave zones send NOTIFY messages after
   loading a new copy of the zone.  They now send the NOTIFY before
   writing the zone data to disk.  This will result in quicker
   propagation of updates in multi-level server structures. [RT #27242]
   "named -V" can now report a source ID string.  (This is will be
   of most interest to developers and troubleshooters).  The source

   ID for ISC's production versions of BIND is defined in the "srcid"
   file in the build tree and is normally set to the most recent
   git hash. [RT #31494]

   Response Policy Zone performance enhancements.  New "response-policy"
   option "min-ns-dots".  "nsip" and "nsdname" now enabled by default
   with RPZ. [RT #32251]
