Infinite reboot when OS upgrade from M to N with set Always-on VPN
Symptom : Infinite reboot
Reproduce step :
1. Set the Always-on VPN in M OS
2. OS upgrade from M to N
Reproduce frequency : 100%
Reason of issue :
https://android.googlesource.com/platform/frameworks/base/+/9a5f485
As you know, in M OS, Always-on VPN information is stored in keystore with encryted.
However, in N OS, there is no encryption when it put in keystore.
So, You deleted keystore check(locked/unlock) logic on ConnectivityService.
By this reason, when device upgrade to N OS(set Always-on VPN), it goes infinite boot.
(Cannot read old always-on vpn information untill device unlock.)
Solution :
I founded exception handling when this case as follows:
If getting Credentials.LOCKDOWN_VPN information has null value(catch the exception),
updateLockdownVpn returns false value.
