fine.

Upgrade to tzdata2013c.

From the release notes:

  Changes affecting current and future time stamps:

    Palestine observed DST starting March 29, 2013.  (Thanks to
    Steffen Thorsen.)  From 2013 on, Gaza and Hebron both observe DST,
    with the predicted rules being the last Thursday in March at 24:00
    to the first Friday on or after September 21 at 01:00.

    Assume that the recent change to Paraguay's DST rules is permanent,
    by moving the end of DST to the 4th Sunday in March every year.
    (Thanks to Carlos Raúl Perasso.)

  Changes affecting past time stamps:

    Fix some historical data for Palestine to agree with that of
    timeanddate.com, as follows:

          The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not
          00:00 Apr 1.

          The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not
          02:00.

          The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27.

          The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2.

          The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01.

          The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00.

    Fix times of habitation for Macquarie to agree with the Tasmania
    Parks & Wildlife Service history, which indicates that permanent
    habitation was 1899-1919 and 1948 on.

  Changing affecting metadata only:

    Macquarie Island is politically part of Australia, not Antarctica.
    (Thanks to Tobias Conradi.)

    Sort Macquarie more-consistently with other parts of Australia.
    (Thanks to Tim Parenti.)

linker: only re-open std* for setuid programs.

get_AT_SECURE() was getting called before linker_env_init() had
been called, and returning the default value ("true"). This was
causing us to reopen closed stdin, stdout, and stderr for ALL
processes, not just privileged (setuid) processes.

Calling path:
  - __linker_init
    - soinfo_link_image
      - get_AT_SECURE
    - __linker_init_post_relocation
      - linker_env_init

This change restores the intended behavior of only re-opening
stdin, stdout, and stderr for privileged processes.

[NETFILTER]: Fix iptables ABI breakage

Pick up Linux kernel patch 2748e5dec7ca8a3804852c7c4171f9156384d15c
from 2007

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2748e5dec7ca8a3804852c7c4171f9156384d15c

[NETFILTER]: Fix iptables ABI breakage on (at least) CRIS
With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.

On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.

Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.

strncpy: implement _FORTIFY_SOURCE=2

Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.

Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.

Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.
