705b46b900 Only show "Connected" note after opening portal
The "Connected" notification would be shown every time a network
validates after being identified as a captive portal. This causes issues
on networks that have auto-login mechanisms, as a high priority
notification would be shown even though the user was not interacting
with the phone.

The "Connected" notification is intended to confirm to the user that
they successfuly logged in (manually), so only show it after the user
opens the portal on the network.

Bug: 134124044
Test: Flashed, connected to portal: notification shown
      Opened portal from command line + revalidate: no notification

5c8f9cf7ed NetworkStats: Fix race condition causing system server crashes
NetworkStatsService uses an internal boolean to know when it has
started for the purpose of preventing access to other internal
variables before they are initialized.

However that boolean is set to true in systemReady() non-atomically
with respect to the initialization of the other variables it guards,
which can cause the system server to crash.

This patch fixes this concurrency bug by moving setting the internal
boolean flag and the variable it guards in one atomic synchronized
block.

This patch also removes code checking if bandwidth control is enabled,
because this is now always true.

Test: Compiled.

9308cd307a NetworkStatsFactory: Take VPNs into account for network/battery stats
This change fixes detailed UID stats to ensure network and battery stats
both take VPNs into account. NetworkStatsFactory is being made aware of
VPNs enabled, and the full set of underlying networks present.

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

This snapshot gets updated whenever NSF records a new snapshot
(based on various hooks such as VPN updating its underlying networks,
network getting lost, etc.), or NetworkStatsService's
getDetailedUidStats() method being called.

This change widens the scope of the existing mPersistentSnapshot lock,
renaming it to mPersistentDataLock, and ensures that TUN migrations are
not done in parallel. Additionally, mVpnInfos is updated via
pointer-swapping, to reduce the scope of the mPersistentDataLock.

The safety of this change is predicated on:
1. NetworkStatsFactory lock not held, so services cannot deadlock through
the cyclical lock.

2. The broadening of the scope of the lock in NetworkStatsFactory has no
threading implications, as it is always the last (leaf node) lock held,
and therefore is impossible to have lock inversion.

Additionally, to ensure VPNs work with 464xlat, the VPN info passed to
the NetworkStatsFactory includes all underlying interfaces, instead of
only passing the first one.

This (partially) re-applies changes from:
aosp/972848: Add one more test for VPN usage stats.
aosp/972847: Addressing comments for http://ag/7700679.
aosp/885338: NetworkStatsService: Fix getDetailedUidStats to take VPNs

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.

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.
