NetworkState is used by many methods that take or return legacy
network types. It is used because it contains most of the state
related to a network.
This code is not easy to follow and is more expensive than it
needs to be: most of the methods that construct a NetworkState
only really need one of its members (e.g., LinkProperties, or
NetworkInfo), but constructing a NetworkState requires making
defensive copies of all its other members as well.
- Instead of using NetworkState, use NetworkAgentInfo, which
already contains all the same data.
- Replace calls to getUnfilteredActiveNetworkState with calls to
getNetworkAgentInfoForUid. When getUnfilteredActiveNetworkState
returned NetworkState.EMPTY, return a null nai, which causes
any caller to see return null LinkProperties/NetworkInfo/etc.
- Rename filterNetworkStateForUid to getFilteredNetworkInfo,
because that's the only thing it actually filters.
- Rename getFilteredNetworkInfo to getFilteredNetworkInfoForType
to avoid having two methods with the same name perform two
different operations. That method was only introduced recently
in aosp/1552503, so it's probably fine to rename it.
Bug: 174123988
Test: passes existing ConnectivityServiceTest
Change-Id: Idfb5e149967266a442b268de6f13a521884dbb8f
The legacy API getNetworkInfo(int type) is expected to return
NetworkInfo objects for all network types supported by the device
even when those network types are not connected.
This requires a lot of fabrication because all the data
structures in ConnectivityService store information about
connected networks, not networks that don't exist.
Worse, the current behaviour is to return BLOCKED instead of
DISCONNECTED if background data is restricted. This obviously
makes no sense, because a disconnected network cannot be
blocked, and because if that network type did connect and was
unmetered (e.g., Wi-Fi), it would no longer be BLOCKED.
This complicates the code, forcing several methods to deal with
a special case of null NetworkCapabilities, no NetworkAgentInfo,
etc.
Fix this by isolating this outlandish behaviour to its own
method. This allows the main codepaths not to have to support
this unusual and not very useful edge case.

UidRange is a data class that is an implementation detail of

SocketUtils contains system APIs for modules to interact for sockets,
wrapping internal APIs. It should be part of the platform to keep access
to the internal APIs.
This involves splitting NetworkUtils.protectVpn to NetworkUtilsInternal,
since SocketUtils and VpnService are the only users of that method.
The @UnsupportedAppUsage NetworkUtils.protectVpn has low usage
count, and is already available through VpnService.protect.

Split out connectivity APIs to connectivity module directories. This
prepares future move of the connectivity code into a mainline module,
but still keeps it implemented by framework-minus-apex for now: the API
stubs are moved to framework-connectivity.stubs, but the implementation
on device remains in the same place.
This allows moving the connectivity code in/out of APEX with minimal
changes.
