topjohnwu	da723b207a	Allow 3rd party code to load pre-specializing ... Magisk's policy is to never allow 3rd party code to be loaded in the zygote daemon process so we have 100% control over injection and hiding. However, this makes it impossible for 3rd party modules to run anything before process specialization, which includes the ability to modify the arguments being sent to these original nativeForkAndXXX methods. The trick here is to fork before calling the original nativeForkAndXXX methods, and hook `fork` in libandroid_runtime.so to skip the next invocation; basically, we're moving the responsibility of process forking to our own hands.	2021-01-10 01:25:30 -08:00
