3a40a0000a Do not hold hash table lock while backtracing.
There is a deadlock if holding the hash table lock while trying to do
a backtrace. Change the code so that the hash table lock is only held
while actually modifying either g_hash_table, or while modifying an
entry from g_hash_table.

a20a35fdda Prevent user-defined basename_r from breaking basename(3).
LP64 is immune because basename_r is hidden there, but on LP32 a basename_r
defined in the executable breaks basename because its call to basename_r
will resolve to that one rather than the one in libc.

It can be replaced with:

7ea817d39e Add some glibc-like #defines for libchrome.
libchrome uses __USE_XOPEN2K8 to decide whether futimens is
available. That's perhaps not the best idea, but there are other
cases where we defined the same feature macros as glibc to aid
portability.

dbb17b2831 Fix alignment after variable-length data.
In the serialized output from netd, the strings come first. Some code
assumes -- reasonably enough -- that it can do unaligned reads of pointers,
so we need to ensure alignment after all the strings.

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);
