94851761a8 Merge "Re-notify if the network goes to PARTIAL." 2019-06-03 12:50:11 +00:00
Chiachang Wang
61e494012d Re-notify if the network goes to PARTIAL.
If NetworkMonitor detects partial connectivity before
EVENT_PROMPT_UNVALIDATED arrives, show the partial
connectivity notification immediately. Re-notify
partial connectivity silently if no internet
notification already there.

29444ae336 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().

7577c856bc 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.

635b441ff9 Add one more test for VPN usage stats.
(cherry picked from commit 20204cdf6a)

Covers the case where the majority of traffic through the VPN is
caused by the VPN app itself, and ensures that that traffic is
correctly attributed to the VPN app as opposed to spread between
the other apps that use the VPN.

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.

5c7c1def90 Always give VPN the INTERNET capability.
Split-tunnel VPN (which are the only ones affected by this change)
always fall through to the default network for routes they don't
handle, and even if the underlying network(s) don't provide access
this may be a pinhole that can actually reach the broader network.

In practice this behaves like the original release of P and is the
safest thing to do for Q. In R we should evaluate giving the VPN
app the ability to simply tell the network stack whether it does
provide Internet access or not.

336e846779 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.

e7094673d5 NetworkStatsService: Fix getDetailedUidStats to take VPNs into account.
(cherry picked from commit 2af0b66aba)

This API is similar to one provided by NetworkStatsFactory with the
difference that NSS also migrates traffic from VPN UID to other apps.

Since traffic can only be migrated over NetworkStats delta, NSS
therefore maintains NetworkStats snapshot across all UIDs/ifaces/tags.

This snapshot gets updated whenever NSS records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or getDetailedUidStats API is invoked by
one of its callers.
