Changes affecting future time stamps
Pacific/Fiji will observe DST from 2014-11-02 02:00 to
2015-01-18 03:00. (Thanks to Ken Rylander for the heads-up.)
Guess that future years will use a similar pattern.
A new Zone Pacific/Bougainville, for the part of Papua New
Guinea that plans to switch from UTC+10 to UTC+11 on
2014-12-28 at 02:00. (Thanks to Kiley Walbom for the
heads-up.)
Changes affecting time zone abbreviations
Since Belarus is not changing its clocks even though Moscow
is, the time zone abbreviation in Europe/Minsk is changing
from FET to its more-traditional value MSK on 2014-10-26 at
01:00. (Thanks to Alexander Bokovoy for the heads-up about
Belarus.)
The new abbreviation IDT stands for the pre-1976 use of UT+8
in Indochina, to distinguish it better from ICT (UT+7).
Changes affecting past time stamps
Many time stamps have been corrected for Asia/Ho_Chi_Minh
before 1976 (thanks to Trần Ngọc Quân for an indirect pointer
to Trần Tiến Bình's authoritative book). Asia/Ho_Chi_Minh has
been added to zone1970.tab, to give tzselect users in Vietnam
two choices, since north and south Vietnam disagreed after our
1970 cutoff.
Asia/Phnom_Penh and Asia/Vientiane have been turned into
links, as they differed from existing zones only for older
time stamps. As usual, these changes affect pre-1970 time
stamps only. Their old contents have been moved to the
'backzone' file.

Fix race condition in timer disarm/delete.
When setting a repeat timer using the SIGEV_THREAD mechanism, it's possible
that the callback can be called after the timer is disarmed or deleted.
This happens because the kernel can generate signals that the timer thread
will continue to handle even after the timer is supposed to be off.
Add two new tests to verify that disarming/deleting doesn't continue to
call the callback.
Modify the repeat test to finish more quickly than before.
Refactor the Counter implementation a bit.

Inline helpers need to be exported unmangled.
__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.
The rest of these didn't cause build failures, but they look suspect

Reimplement clock(3) using clock_gettime(3)
Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.
It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
not 1920-01-06. The old entry was based on a misinterpretation of Shanks.

__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different

Fix pthread_getattr_np for the main thread.
On most architectures the kernel subtracts a random offset to the stack
pointer in create_elf_tables by calling arch_align_stack before writing
the auxval table and so on. On all but x86 this doesn't cause a problem
because the random offset is less than a page, but on x86 it's up to two
pages. This means that our old technique of rounding the stack pointer
doesn't work. (Our old implementation of that technique was wrong too.)
It's also incorrect to assume that the main thread's stack base and size
are constant. Likewise to assume that the main thread has a guard page.
The main thread is not like other threads.
This patch switches to reading /proc/self/maps (and checking RLIMIT_STACK)
whenever we're asked.

Fix unistd.getpid_caching_and_clone.
This test only works if you're root (strictly: if you have permission to
CLONE_NEWNS), so it's useful to us when we're doing ad hoc testing (since
that's usually done as root), but it's not useful as part of CTS or when
running the tests on the host.
