faee26026f Don't use a high-priority notification on auto-join.
If the device connects to a network automatically and not through
user action, a high-priority notification is intrusive and is
inconsistent with other networking notifications, which are
usually only high priority if the network is manually selected.

72792e2f8f Allow passing in acceptUnvalidated without explicitlySelected
This will allow wifi to tell ConnectivityService that partial
connectivity is acceptable even if the network is not explicitly
selected.

This is needed when the user selects a partial connectivity
network and tells the system to connect to the network, and never
to ask again. In such cases, the system must switch to the
network even if it is not explicitly selected.

since it is not in framework. Moves NattKeepalivePacketData to
framework to make it can be utilized by telephony.

This change also removes the error feedback triggered by calling
add keepalive packet filter to an unsupported network agent. This

90913e9a37 Fix NullPointerException in ConnectivityService
[Problem]
NullPointerException occurs in ConnectivityService when boot up.

[Root Cause]
When ConnectivityService starts up, isTetheringSupported may access
UserManager that has not been created yet. Therefore,
NullPointerException occurs.

[Solution]
Changed to create UserManager before makeTethering().

98504571be Don't crash ConnectivityService if the network stack crashes.
When the network stack crashes, the system will rebind to it.
Existing references are no longer useful (they just throw
RemoteException) but if the system is still up, then the user
can at least recover the situation by taking actions such as
going into airplane mode, toggling wifi, etc.

This CL stops ConnectivityService from crashing the system when
it cannot talk to NetworkMonitor. This is arguably better than
crashing the system, because crashing the system is disruptive
and carries the serious risk of a bootloop from which it is not
possible to recover.

NetworkStackClient already contains code to crash the system
when the network stack crashes. This change help ensure that
if a crash occurs, it is the result of an explicit decision by
that code instead of an unchecked exception in one of the callers
of the network stack.

Bug: b/133174607
Test: Manual. The simplest artifact is observed by watching the output of
adb shell dumpsys meminfo -d com.android.networkstack | grep 'Proxy Binders'
while connecting and disconnecting multiple times to any network.
This will display the number of binder proxies. Before this, the binder
proxy count increases by 1 with each connection and never goes down (there
is some noise, as proxy objects are sometimes created for other reasons,
and get GC'd eventually). After this, the binder proxy count is always
eventually stable at 27 + connected network count.

See the bug for the complete analysis.

1ec284f9d2 Don't auto-connect to networks that have no/limited connectivity.
Auto-reconnecting to a network with no or limited Internet
connectivity is not useful. This is because such networks cannot
be used unless the user taps the notification and interacts with
the resulting dialog. But the notification is only shown if the
user manually connects to the network, not if the system
auto-connects to it.

75387c9ced Update multiple validation result to ConnectivityService
Once a network is determined to have partial connectivity, it
cannot go back to full connectivity without a disconnect. This
is because NetworkMonitor can only communicate either
PARTIAL_CONNECTIVITY or VALID, but not both. Thus, multiple
validation results allow ConnectivityService to know the real
network status.
