* Remove old fork-and-specialize APIDave Platt2014-02-191-18/+1
| | | | | | | | | As promised, this is the cleanup patch-set which removes the old native "fork and specialize" API, which has been replaced by a slightly-enhanced one which can close the Zygote socket descriptors in the Zygote child. Change-Id: I33f504afd242e268863270139b4e421d4b0728f2
* Finish fixing Zygote descriptor leakage problemDave Platt2014-02-191-3/+76
| | | | | | | | | | | | | | | | | | In order to prevent Zygote descriptors from leaking into the child environment, they should be closed by the forked-off child process before the child switches to the application UID. These changes close the descriptors via dup2(), substituting a descriptor open to /dev/null in their place; this allows the Zygote Java code to close the FileDescriptor objects cleanly. This is a multi-project change: dalvik, art, libcore, frameworks/base, and external/sepolicy are affected. The CLs need to be approved together, lest the build break or the software fail to boot.

* Dalvik: Ensure that the array length complies with the final specifierSerban Constantinescu2013-12-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | JSR-133, which Android 4 should comply with, "final" fields should be visible to all threads at the time the constructor exits, regardless of synchronization. This behaviour should also apply to the array lengths as they are regarded as equivalent in behaviour to "final" fields. Non-final fields require explicit synchronization in Java for them to be accessed correctly. The Dalvik VM in Android ensures constructors for ordinary object behave properly by inserting a memory barrier ("DMB") on their return if the object's class has a "final" field. The issue, however, is that while Dalivk inserts a barrier in constructors, it doesn't during array create. A barrier ought to be inserted in order to ensure an array's length is visible when the array itself can be observed by other threads. In order for Dalvik to be correct in respect to JSR-133 and the ARM memory model, it should be modified to have a memory barrier after an array is allocated and initialized, before it is visible to other threads.
