b9f76dc829 Update timezone data to 2015e
Changes affecting future time stamps

    Morocco will suspend DST from 2015-06-14 03:00 through 2015-07-19 02:00,
    not 06-13 and 07-18 as we had guessed.  (Thanks to Milamber.)

    Assume Cayman Islands will observe DST starting next year, using US rules.
    Although it isn't guaranteed, it is the most likely.

a05bee544a Fixed uchar.h for clang3.6
The NDK self-test issue64679-prctl failed to build because by default
clang3.6 builds in C11 mode, but the ifdef in the file 'uchar.h' hid the
required char16_t and char32_t declarations based on the GCC version,
which is declared as 4 by clang.

The ifdef is changed so that it is based on C version rather than a
compiler version. This way it is compatible with gcc 4, gcc 5 and clang
which are actually the only used toolchains.

01e37c9665 Pass around struct android_net_context for better behaviour
Group network context elements in to a single struct and
add a version of android_getaddrinfofornet() that accepts it.

The introduction of UID-based routing means that the UID is an
integral part of the network context when evaluating connectivity,
sorting addresses, etc.

Also, introduce a distinction between DNS netids/marks and those
expected to be used by the application.  This can be important
when the network an application is using is not the same as the
network on which DNS queries will be issued.

Additionally, de-duplicate the UDP connect logic (collapse both
_test_connect() and _find_src_addr() into just the latter).

0577733c2e Avoid name collision with user_fpsimd_state in <asm/ptrace.h>.
We don't want to use <asm/ptrace.h> because (a) it'll drag in a bunch of
namespace pollution and (b) the registers should be "long double" for
userspace, not the kernel's uint128s. So just use a slightly different
name for our struct (which matches the traditional names for these structs
anyway).

60907c7f4e Allow NULL in pthread_mutex_lock/unlock.
The pthread_mutex_lock and pthread_mutex_unlock were allowed to
fail silently on L 32 bit devices when passed a NULL. We changed
this to a crash on 32 bit devices, but there are still games that make
these calls and are not likely to be updated. Therefore, once again
allow NULL to be passed in on 32 bit devices.

19fee2ca8b Fix a few libc makefile mishaps.
These are the problems fixed in this CL:

- The ndk_cruft.cpp file was not compiled for 64 bit.
- Some files where not compiled for libc_bionic.a due to a missing
  patch-up-arch-specific-flags call.
- The libc_bionic_ndk.a patch up call was using bionic src, not
  the bionic_ndk_src_files.
- Move mmap.cpp to the ndk src list where it was before because of
  the above errors.

2825f10b7f libc: Add O_PATH support for fgetxattr / fsetxattr
Support O_PATH file descriptors when handling fgetxattr and fsetxattr.
This avoids requiring file read access to pull extended attributes.

This is needed to support O_PATH file descriptors when calling
SELinux's fgetfilecon() call. In particular, this allows the querying
and setting of SELinux file context by using something like the following
code:

  int dirfd = open("/path/to/dir", O_DIRECTORY);
  int fd = openat(dirfd, "file", O_PATH | O_NOFOLLOW);
  char *context;
  fgetfilecon(fd, &context);

    Egypt will not observe DST in 2015 and will consider canceling it
    permanently.  For now, assume no DST indefinitely.
    (Thanks to Ahmed Nazmy and Tim Parenti.)

  Changes affecting past time stamps

    America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not
    1966-07-01.  Also, Yukon's time zone history is documented better.
    (Thanks to Brian Inglis and Dennis Ferguson.)

  Change affecting past and future time zone abbreviations

    The abbreviations for Hawaii-Aleutian standard and daylight times
    have been changed from HAST/HADT to HST/HDT, as per US Government
    Printing Office style.  This affects only America/Adak since 1983,
    as America/Honolulu was already using the new style.

bfd65279a5 bionic: add __system_property_area_serial()
Adds a new _internal_ function. Provide a global serial number to
support more efficient private caching algorithms. This allows
to skip re-running the __system_property_find() call on misses until
there is a global change in the properties. This call is a read
barrier, the property data to be read following this call will be
read sequentially and up to date.

Changes affecting future time stamps

    Egypt's spring-forward transition is at 24:00 on April's last Thursday,
    not 00:00 on April's last Friday.  2015's transition will therefore be on
    Thursday, April 30 at 24:00, not Friday, April 24 at 00:00.  Similar fixes
    apply to 2026, 2037, 2043, etc.  (Thanks to Steffen Thorsen.)

  Changes affecting past time stamps

    The following changes affect some pre-1991 Chile-related time stamps
    in America/Santiago, Antarctica/Palmer, and Pacific/Easter.

      The 1910 transition was January 10, not January 1.

      The 1918 transition was September 10, not September 1.

      The UTC-4 time observed from 1932 to 1942 is now considered to be
      standard time, not year-round DST.

      Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31,
      then reverted to standard time, then switched its time zone to
      UTC-5 on 1947-04-01.

      Assume transitions before 1968 were at 00:00, since we have no data
      saying otherwise.

      The spring 1988 transition was 1988-10-09, not 1988-10-02.
      The fall 1990 transition was 1990-03-11, not 1990-03-18.

      Assume no UTC offset change for Pacific/Easter on 1890-01-01,
      and omit all transitions on Pacific/Easter from 1942 through 1946
      since we have no data suggesting that they existed.

    One more zone has been turned into a link, as it differed
    from an existing zone only for older time stamps.  As usual,
    this change affects UTC offsets in pre-1970 time stamps only.
    The zone's old contents have been moved to the 'backzone' file.
    The affected zone is America/Montreal.

3391a9ff13 Simplify close(2) EINTR handling.
This doesn't affect code like Chrome that correctly ignores EINTR on
close, makes code that tries TEMP_FAILURE_RETRY work (where before it might
have closed a different fd and appeared to succeed, or had a bogus EBADF),
and makes "goto fail" code work (instead of mistakenly assuming that EINTR
means that the close failed).

Who loses? Anyone actively trying to detect that they caught a signal while
in close(2). I don't think those people exist, and I think they have better
alternatives available.

95f1ee235a Change on handling of SIGEV_THREAD timers.
1. Don't prevent calling callback when SIGEV_THREAD timers are disarmed by timer_settime.
As in POSIX standard: The effect of disarming or resetting a timer with pending
expiration notifications is unspecified. And glibc didn't prevent in this situation, so I
think it is fine to remove the support.
2. Still prevent calling callback when SIGEV_THREAD timers are deleted by timer_delete.
As in POSIX standard: The disposition of pending signals for the deleted timer is unspecified.
However, glibc handles this (although that is not perfect). And some of our tests in
time_test.cpp depend on this feature as described in b/18039727. so I retain the support.
3. Fix some flaky test in time_test.cpp, and make "time*" test pass on bionic-unit-tests-glibcxx.

76615dae93 Provide writer preference option in rwlock.
Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:

1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.

2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.

3. Add writer preference option.

4. Add unit tests for rwlock.

d6bf3d5e19 Don't export new/delete from libc shared libraries.
This used to be handled by -fvisibility=hidden on libc_cxa, but that
was broken by the resolution of https://llvm.org/PR22419 (introduced
to Android in today's clang update).

Now we just use a version script that prevents these from being
re-exported from our shared libraries.

Yabin Cui
28e69f7508 Add O_APPEND flag for __libc_write_stderr.
For DeathTests, we are testing the output of stderr to check if it is the
death we are expecting. To collect the output, Gtest redirects stderr to
a temporary file. But in __libc_write_stderr in libc_logging.cpp, we are
writing to stderr without a O_APPEND flag, so a new message will overwrite
a previous message.
The above situation makes almost all the DeathTests fail on host. Because
the expected message are always overwritten in host DeathTests. So I add
O_APPEND flag in __libc_write_stderr, which makes all host DeathTests pass.

ee7649c5ac set errno to ENOENT in getauxval per glibc 2.19
Bionic's getauxval(...) implementation returns zero when entries are
missing. Zero can be a valid value, so there is no unambiguous way of
detecting an error. Since glibc 2.19, errno is set to ENOENT when an
entry is missing to make it possible to detect this. Bionic should match
this behavior as code in the Linux ecosystem will start relying on it to
check for the presence of newly added entries.

/dev/mem (and /dev/kmem) are not enabled in the kernels, and selinux
prevents access and makes it a rule compilation error to enable
access. No code uses the _PATH_MEM macro. Remove definition to
suppress future usage.

  Fix "faccessat ignores flags"
2015-02-24 21:52:36 +00:00
Nick Kralevich
35778253a5 Fix "faccessat ignores flags"
The kernel system call faccessat() does not have any flags arguments,
so passing flags to the kernel is currently ignored.

Fix the kernel system call so that no flags argument is passed in.

Ensure that we don't support AT_SYMLINK_NOFOLLOW. This non-POSIX
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/access.html)
flag is a glibc extension, and has non-intuitive, error prone behavior.

For example, consider the following code:

  symlink("foo.is.dangling", "foo");
  if (faccessat(AT_FDCWD, "foo", R_OK, AT_SYMLINK_NOFOLLOW) == 0) {
    int fd = openat(AT_FDCWD, "foo", O_RDONLY | O_NOFOLLOW);
  }

The faccessat() call in glibc will return true, but an attempt to
open the dangling symlink will end up failing. GLIBC documents this
as returning the access mode of the symlink itself, which will
always return true for any symlink on Linux.

Some further discussions of this are at:

  * http://lists.landley.net/pipermail/toybox-landley.net/2014-September/003617.html
  * http://permalink.gmane.org/gmane.linux.lib.musl.general/6952

AT_SYMLINK_NOFOLLOW seems broken by design. I suspect this is why this
function was never added to POSIX. (note that "access" is pretty much
broken by design too, since it introduces a race condition between
check and action). We shouldn't support this until it's clearly
documented by POSIX or we can have it produce intuitive results.

Don't support AT_EACCESS for now. Implementing it is complicated, and
pretty much useless on Android, since we don't have setuid binaries.
See http://git.musl-libc.org/cgit/musl/commit/?id=0a05eace163cee9b08571d2ff9d90f5e82d9c228
for how an implementation might look.
