Summary of changes in tzdata2015a (2015-01-29 22:35:20 -0800):
* The Mexican state of Quintana Roo, represented by America/Cancun,
will shift from Central Time with DST to Eastern Time without DST
on 2015-02-01 at 02:00.
* Chile will not change clocks in April or thereafter; its new standard time
will be its old daylight saving time. This affects America/Santiago,
Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.)
* New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
* Iceland observed DST in 1919 and 1921, and its 1939 fallback
transition was Oct.
* Some more zones have been turned into links, when they differed
from existing zones only for older time stamps.
* Changes affecting commentary.
* Only release the DHCPv6 lease when dropping it.
* Fix handling of ND6_IFF_OVERRIDE_RTADV on BSD.
* Include paths.h to get _PATH_BPF. Thanks to Joerg Sonnenberger.
* Report a better error of the kernel lacks a BPF equivalent filter.
* Implement RFC4941, Privacy Extensions for Stateless Address
Autoconfiguration in IPv6 when dhcpcd is overriding the in-kernel
RA support. For BSD, this is a full userland implementation.
* reject <option> will now reject any DHCP message that contains
that option.
* Ignore RA's from ourself for very badly configured stations.
- Old JIT is removed.
- Improvements to debug information handling.
- ARM: check for deprecated instructions and warn in the integrated
assembler
- PPC: VSX support, va_arg support for struct/union types, -fPIC vs
-fpic supported, faster atomics
- x86: improved vectorizer

- allow separate configurations for local and remote addresses, implementing
effectively whitelists, requested by dh@
- allow the mask of the filter to be specified, requested by dh@
- the db file format has been changed to accommodate these changes, and
needs to be removed.
- Fix for DMARC implementations based on SPF policy plus DKIM Milter. The
PREPEND access/policy action added headers ABOVE Postfix's own Received:
header, exposing Postfix's own Received: header to Milters (protocol
violation) and hiding the PREPENDed header from Milters. PREPENDed
headers are now added BELOW Postfix's own Received: header and remain
visible to Milters.
- The Postfix SMTP server logged an incorrect client name in reject
messages for check_reverse_client_hostname_access and
check_reverse_client_hostname_{mx,ns}_access. They replied with the
verified client name, instead of the name that was rejected.
- The TLS client logged that an anonymous TLS connection was "Untrusted",
instead of "Anonymous".
- Fix for configurations that prepend message headers with Postfix access
maps, policy servers or Milter applications. Postfix now hides its own
Received: header from Milters and exposes prepended headers to Milters,
regardless of the mechanism used to prepend a header. This fix reverts
a partial solution that was released on October 13, 2014, and replaces
it with a complete solution.
atf/atf-c++/macros_test/detect_unused_tests as expected failures
when using versions of GCC where they are known to fail, with a

When decompressing with -N or -NT, strip any path from header name.
This uses the path of the compressed file combined with the name
from the header as the name of the decompressed output file. Any
path information in the header name is stripped. This avoids a
possible vulnerability where absolute or descending paths are put
in the gzip header.
--
as it is needed for the "includes" phase. Make it symlink all necessary
headers in obj to decouple it from "includes" itself, breaking the
dependency cycle. Move the do-x11 target between do-lib and do-build, so
that libraries can get the benefit of build_install (correct .WAIT
behavior) and everything else like "includes" uses the plain SUBDIR
entry in external/mit.
From Alan Modra: Wed, 3 Jul 2013 11:51:56 +0930: powerpc64 call stubs:
This brings powerpc64 ld in line with gold regarding calls allowed to
go via a plt call stub or toc-adjusting stub without a following nop.
A long time ago ld allowed tail calls, but this is wrong because we'll
return to the caller's caller with the wrong toc pointer. I fixed
that for shared libraries but allowed tail calls in an executable for
some reason. Probably just muddy thinking on my part, because there's
no difference between an executable and a shared library regarding the
need to restore the toc pointer. Perhaps it was because some testcase
failed, most likely due to the g++ issue I comment on in the patch.
From Alan Modra: 29 Aug 2014 01:22:29 +0000: PowerPC64 call lacks nop error:
Enough people accidentally or otherwise use -mcmodel=small then wonder
why a call that is local is behaving as if it is going via the PLT.
* elf64-ppc.c (ppc64_elf_relocate_section): Report a different
error for calls via a toc adjusting stub without a nop.
problems with compiling atomics for the riscv64 target with gcc. Remove
the now-unneeded workarounds for the 2 files in libasan that were formerly
failing to compile with the optimizer turned on.
- Fix a conditional
- Don't include bsd.lib.mk if we are not building libraries
(otherwise we end up with an empty library name that installed
bogus library files lib.a etc.)
- Allow signals while reading the user crontab file; doing "crontab -"
does not let you abort otherwise, and doing ^Z, kill %1 leaves turds
in /var/cron/tabs
