Modern network agents are supposed to have the following
lifecycle :
• Construct the agent
• Declare itself to connectivity by calling #register()
• Possibly do some setup
• Declare connected by calling #markConnected()
• Declare disconnected by calling #unregister()
Internally ConnectivityService still manages the state
with deprecated NetworkInfo, which has a lot of possible
detailed states, most of which are now unused. Internally,
the steps above translate to the states below :
• When the agent calls #register() it starts in state
CONNECTING
• When it calls #markConnected() it goes to CONNECTED
• When it calls #unregister() it goes to DISCONNECTED which
triggers the flow that disconnects it immediately
• ConnectivityService also synthesizes the SUSPENDED state
under some situations, but that's not relevant here.
The translation above is done by the NetworkAgent class,
which translates #register(), #markConnected() and
The only valid lifecyle for new agents is thus :
CONNECTING → CONNECTED → disconnect
↕ ↑
SUSPENDED ───┘
Note that in the above scheme, there is no space for the
UNKNOWN state, which is only used by legacy network agents.
However, the constructor for NetworkInfo still starts with
UNKNOWN. Ideally the constructor for NetworkInfo would set
the info to CONNECTING instead, but this would be a very
visible change in behavior affecting many apps (especially
their tests), so for backward compatibility we can't do
that.
New network agents however don't expose their NetworkInfo
to the client code, so they can just be made to start in
CONNECTING the way it was meant.
Note that this didn't really have a concrete impact beyond
printing some logs as by and large the ConnectivityService
code handles UNKNOWN and CONNECTING the same way, or more
exactly it handles transitions to CONNECTED from UNKNOWN
and CONNECTING in the same way. The exception to this is
VPNs, which are not using the new agent API yet, and the
upcoming conversion is why this fix is actually needed now.

Currently, the callbacks of stopping were fired when stop procedure
is started, because the upper layer apps only care about the reason
of stopping instead of stopping result. Thus, there is no need to
wait for the result comes back. However, this behavior generates
races if apps want to re-start keepalive immediately since the
resources are not released yet.

This patch is still needed and should go in now that the
error is fixed.
The patch was submitted into rvc-dev and is already in
rvc-dev-plus-aosp (patch in in ag/11923559, revert
skipped in ag/12072199). A follow-up will remove the
unused services.net-module-wifi target.

For non-telephony networks, this was always set to 0 before R.
In R, it is currently set to the same value as the network type.
This is incorrect because the two have different namespaces.
or example, currently, any network of type WIFI (==1) will have
a subtype of NETWORK_TYPE_GPRS (==1). Similarly, all ETHERNET
networks will have subtype NETWORK_TYPE_1XRTT, all VPN networks
will have a subtype of NETWORK_TYPE_TD_SCDMA, etd.

Also refine comments in DhcpResults following feedback in previous

This is a Client-only solution.
- Add to NetdClient a per-process std::atomic_boolean
similar to netIdForProcess and netIdForResolv.
- The boolean says whether the process should be
allowed Internet connectivity.
- Add an @hide method to NetUtils.java to set the boolean;
call it from the initialization code of the new
process just after forking from zygote.
- Make netdClientSocket and dnsOpenProxy check the
boolean. If the boolean is false, return EPERM from
socket calls.
