5ae44f302b linker: handle R_ARM_COPY relocations in a proper way
If an executable contain copy relocations, other references
to the symbol it points to should be preempted and made to
point to the copy instead.

Also, the linker should make sure the target area has
sufficient space to contain the copy. It also checks
whether the library that supplies the symbol is built
with -Bsymbolic, and errors out if this is the case.

18a206c81d More dynamic linker cleanup.
I still want to break linker_format out into its own library so we can reuse
it for malloc debugging and so forth. (There are many similar pieces of code
in bionic, but the linker's one seems to be the most complete/functional.)

58b575485c Clean up the <libgen.h> implementation a little, bring in tests.
Most of these tests were in system/extras, but I've added more to cover other
cases explicitly mentioned by POSIX.

10ce96944e Fix bug in pthread_join, pthread_exit, pthread_detach
pthread_no_op_detach_after_join test from bionic-unit-tests hangs
on x86 emulator. There is a race in the pthread_join, pthread_exit,
pthread_detach functions:
- pthread_join waits for the non-detached thread
- pthread_detach sets the detached flag on that thread
- the thread executes pthread_exit which just kills the now-detached
thread, without sending the join notification.

This patch improves the test so it fails on ARM too, and modifies
pthread_detach to behave more like glibc, not setting the detach state if
called on a thread that's already being joined (but not returning an error).

ae8eb74675 Fix a potential NULL pointer dereference in _init_thread().
The first NULL pointer check against `attr' suggests that `attr' can
be NULL.  Then later `attr' is directly dereferenced, suggesting the
opposite.

    if (attr == NULL) {
        ...
    } else {
        ...
    }
    ...
    if (attr->stack_base == ...) { ... }

The public API pthread_create(3) allows NULL, and interprets it as "default".
Our implementation actually swaps in a pointer to the global default
pthread_attr_t, so we don't need any NULL checks in _init_thread. (The other
internal caller passes its own pthread_attr_t.)

33c4a3adde Merge "libc: Fix alphasort() signature (and implementation)." 2012-10-29 07:45:13 -07:00
David 'Digit' Turner
c30396f5f2 libc: Fix alphasort() signature (and implementation).
The declaration for alphasort() in <dirent.h> used the deprecated:

  int alphasort(const void*, const void*);

while both Posix and GLibc use instead:

  int alphasort(const struct dirent** a, const struct dirent** b);

See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html

This patch does the following:

- Update the declaration to match Posix/GLibc
- Get rid of the upstream BSD code which isn't compatible with the new
  signature.
- Implement a new trivial alphasort() with the right signature, and
  ensure that it uses strcoll() instead of strcmp().
- Remove Bionic-specific #ifdef .. #else .. #endif block in
  dirent_test.cpp which uses alphasort().

Even through strcoll() currently uses strcmp(), this does the right
thing in the case where we decide to update strcoll() to properly
implement locale-specific ordered comparison.

ad88a08631 Per-thread -fstack-protector guards for x86.
Based on a pair of patches from Intel:

  https://android-review.googlesource.com/#/c/43909/
  https://android-review.googlesource.com/#/c/44903/

For x86, this patch supports _both_ the global that ARM/MIPS use
and the per-thread TLS entry (%gs:20) that GCC uses by default. This
lets us support binaries built with any x86 toolchain (right now,
the NDK is emitting x86 code that uses the global).

I've also extended the original tests to cover ARM/MIPS too, and
be a little more thorough for x86.

20aa6c0f4c Workaround g++ 4.7 compfail
error: C99 designator 'name' outside aggregate initializer

G++ 4.7+ can't handle some of C99 designated initializers.
Most likely it's just not implemented yet. Other possible workarounds is
to compile this as C not C++ or define name as char* instead of char[SIZE].

Also separate out the C++ files so we can use -Werror on them. I'd
rather wait for LOCAL_CPPFLAGS to be in AOSP, but this also lets us
see which files still need to be sorted into one bucket or the other.
