Android L regressions #326

Open GoogleCodeExporter opened 9 years ago

1. Conflict with libsigchain.so, which also intercepts sigaction.
2. Missing libcorkscrew.so. We need a different way to unwind from a signal 
handler.

Status:
* current bionic master branch has a number of fixes to symbol resolution and 
signal unwinding. When that's released, we won't need libcorkscrew.so anymore.
* asan_device_setup sets allow_user_segv_handler=1 to allow libsigchain to take 
priority. Our segv handler becomes the first in line after libsigchain's, so 
everything works as before.
* asan_device_setup sets SELinux labels properly so that enforcing mode works 
fine.

Basically, everything works on master branch.

Can you attach the latest asan_device_setup.sh ? Mike can test it out and make 
sure stuff works on L correctly. Mike, you will see a copy of this in 
ClusterFuzz (with some changes). You would need to add the new changes in that 
file (you can't just replace it since it has some local changes needed for 
ClusterFuzz to work).
