Merge "Add check for pthread_self() when looking up a thread"
Dimitry Ivanov [Fri, 5 Feb 2016 00:21:01 +0000 (16:21 -0800)]
Add check for pthread_self() when looking up a thread
Check if thread_id is in fact pthread_self before
locking on g_thread_list_lock in __pthread_internal_find.
The main reason for doing this is not performance but to allow
the linker use raise() which was not working because pthread_kill()
couldn't find pthread_self() thread because the global thread
list is initialized in libc.so and the linker's version of this
list is empty.

C99 - 6.7.4
"An inline definition of a function with external linkage shall not contain
a definition of a modifiable object with static storage duration, and shall
not contain a reference to an identifier with internal linkage."
As standard does not require compiler to determine when it is safe to
reference an internal function in an external inline function, but instead
delegalizes such reference as a whole, gcc throws a warning for such code
under C99 compilation. Warning produced by libc header is inhereted widely
and strips the option of using -Werror to track code sanity.
Replace static inline specifier with gnu89 extern inline. Latter "is used
only for inlining. In no case is the function compiled on its own", which
is slightly different from former semantically, but should produce the same
result here.

- Change the tag when a pointer is freed so it's easy to detect if
an already freed pointer is being used.
- Move the free backtrace out of the header. This backtrace is only
used under only some circumstances, so no need to allocate space
in all headers for it.
- Add new option free_track_backtrace_num_frames to specify how many
frames to record when the free occurs. This removes the dependency

Malloc debug rewrite.
The major components of the rewrite:
- Completely remove the qemu shared library code. Nobody was using it
and it appears to have broken at some point.
- Adds the ability to enable/disable different options independently.
- Adds a new option that can enable the backtrace on alloc/free when
a process gets a specific signal.
- Adds a new way to enable malloc debug. If a special property is
set, and the process has an environment variable set, then debug
malloc will be enabled. This allows something that might be
a derivative of app_process to be started with an environment variable
being enabled.
- get_malloc_leak_info() used to return one element for each pointer that
had the exact same backtrace. The new version returns information for
every one of the pointers with same backtrace. It turns out ddms already
automatically coalesces these, so the old method simply hid the fact
that there where multiple pointers with the same amount of backtrace.
- Moved all of the malloc debug specific code into the library.
Nothing related to the malloc debug data structures remains in libc.
- Removed the calls to the debug malloc cleanup routine. Instead, I
added an atexit call with the debug malloc cleanup routine. This gets
around most problems related to the timing of doing the cleanup.
The new properties and environment variables:
libc.debug.malloc.options
Set by option name (such as "backtrace"). Setting this to a bad value
will cause a usage statement to be printed to the log.
libc.debug.malloc.program
Same as before. If this is set, then only the program named will
be launched with malloc debug enabled. This is not a complete match,
but if any part of the property is in the program name, malloc debug is
enabled.
libc.debug.malloc.env_enabled
If set, then malloc debug is only enabled if the running process has the
environment variable LIBC_DEBUG_MALLOC_ENABLE set.

Add _seek64 to FILE.
Move fdopen/fopen/freopen and change them to initialize _seek64 instead
of the legacy _seek. The in-memory streams can stick with _seek for now,
since you're not going to fit a > 4GiB in-memory stream on a 32-bit device
anyway.

Put struct FILE back how NDK-built apps expect it.
The first rule of stdio is you never change struct FILE. This broke all
NDK-built apps that used stdin/stdout/stderr. (Which is more than you
might think, given that those streams don't go anywhere useful. Svelte!)
I've added a big code comment because I knew when I removed the field that
doing so was a mistake, but I couldn't think why.

Add another stdio test.
This test didn't catch anything, but it does ensure that we exercise
the "lots of files" case.

Do not unmap reserved region on dlclose
dlclose used to unmap the part of the reserved region
for ANDROID_DLEXT_RESERVED_ADDRESS that was neccessary
to map PT_LOAD segments. With this change dlclose
replaces mapped PT_LOAD segments with a PROT_NONE,
MAP_ANONYMOUS | MAP_NORESERVE.
Previously caller was unmapping the reserved region after
the failed dlclose which led to race condition when someone
else reused the region freed by dlclose but before the unmap
by the chromium code.

Remove dependency on zipalign.
Roll our own version of zipalign so that we can break the dependency
on the build tools zipalign. This breaks the transitive dependency
on androidfw so that building bionic unit tests in brillo works again.
Also modify the DlExtTest.ExtInfoUseFdWithOffset test so it dynamically
gets the offset of the shared library inside of the zip instead of
hard-coding the value.
