__COUNTER__ allows one to obtain incrementing (read: unique) numbers
from the C preprocesor. This is useful when implementing things like a
robust implementation of CTASSERT(), which currently fails when using
it more than once on a single line of code. Probably not likely to cause
any breakage, but still.
__COUNTER__ was also added to GCC 4.3, but since that implementation is
GPLv3 licensed, I took the liberty of implementing it without looking at
any upstream sources. Therefore, this version is licensed under the same
license as the rest of the code; GPLv2.

Recursive name servers are failing with an assertion:
INSIST(! dns_rdataset_isassociated(sigrdataset))
At this time it is not thought that authoritative-only servers
are affected, but information about this bug is evolving rapidly.
Because it may be possible to trigger this bug even on networks
that do not allow untrusted users to access the recursive name
servers (perhaps via specially crafted e-mail messages, and/or
malicious web sites) it is recommended that ALL operators of
recursive name servers upgrade immediately.

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.

for resolving by a child process that, upon success, will add the entry
to the config of the running running parent process.
Unfortunately there are a couple of bugs with this, fixed in various
later versions of upstream in potentially different ways due to other
code changes:
1) Upon server [-46] <FQDN> the [-46] are used as FQDN for later resolving
which does not work. Make sure we always pass the name (or IP there).
2) The intermediate file to carry the information to the child process
does not know about -4/-6 restrictions, so that a dual-stacked host
could resolve to an IPv6 address but that might be unreachable (see
r223626) leading to no working synchronization ignoring a IPv4 record.
Thus alter the intermediate format to also pass the address family
(AF_UNSPEC (default), AF_INET or AF_INET6) to the child process
depending on -4 or -6.
3) Make the child process to parse the new intermediate file format and
save the address family for getaddrinfo() hints flags.
4) Change child to always reload resolv.conf calling res_init() before
trying to resolve names. This will pick up resolv.conf changes or
new resolv.confs should they have not existed or been empty or
unusable on ntp startup. This fix is more conditional in upstream
versions but given FreeBSD has res_init there is no need for the
configure logic as well.

The binutils update in r218822 caused the MIPS n64 dynamic binaries to
fail because the ".interp" section is not in the initial sections.
This happens because elf64bmip-defs.sh overrides INITIAL_READONLY_SECTIONS
to add ".MIPS.options" sections instead of the ".reginfo" section used
by n32.
This used to work fine, but after r218822, INITIAL_READONLY_SECTIONS also
contains the .interp section, so the override has to be done differently.

* elf64-sparc.c (sparc64_elf_relocate_section): Adjust addend of
dynamic relocs against section symbols for the output section vma.
However, with the addition of TLS support in the upstream rev. 1.104
this fix was essentially reverted. After factoring out the common parts
of elf32-sparc.c and elf64-sparc.c a comment was added to elfxx-sparc.c
in the upstream rev. 1.27 as part of unrelated changes, saying that the
fix from elf64-sparc.c rev. 1.61 indeed should be implemented, but given
that some unspecified OS has a broken ld.so expecting broken relocations
deliberately is omitted.
As the current behavior actually violates the SPARC ABI, FreeBSD never
had such a broken ld.so and this is actually causing problems with at
least kernel modules linked with binutils 2.17.50 committed in r218822
without the workaround committed in r219340 in place, re-implement the
above fix in a way so that is only applied if the output format is
ELFOSABI_FREEBSD. In the upstream version it probably would make sense
to invert this check and only skip adjusting the addend for the OS with
the broken ld.so, once it's determine which one that is.

There are several bugfixes in this update, but the most important one is
to ensure __start_ and __stop_ symbols for linker sets and kernel module
metadata are always emitted in object files:
http://llvm.org/bugs/show_bug.cgi?id=9292
Before this fix, if you compiled kernel modules with clang, they would
not be properly processed by kldxref, and if they had any dependencies,
the kernel would fail to load those. Another problem occurred when
attempting to mount a tmpfs filesystem, which would result in 'operation
not supported by device'.
arguments passed to ld, when linking. This was to appease configure
scripts in several ports, that grep for such a -L option in "${CC} -v"
output, to determine the startup objects passed to ld. Note ld itself
does not need to be told about /usr/lib, since it has this path builtin
anyway.
However, if clang is built as a bootstrap tool during buildworld, it
should not use *anything* outside ${WORLDTMP} to include or link with.
The upstream fix to add -L/usr/lib breaks this assumption, and can thus
cause libraries from /usr/lib to be linked in during buildworld.
This can result in buildworld dying during linking of zinject, where it
picks up the wrong copy of libzpool.so, eventually leading to:
/usr/obj/usr/src/tmp/lib/libthr.so.3: undefined reference to `_rtld_get_stack_prot'
Fix this issue by not adding any hardcoded paths, but by looping through
the run-time library path list, which is already correctly set for the
bootstrap phase.
