017bfba0d8 Protect invalid entitlement app configuration
There is a protection in Settings that Settings would gray out if
tethering requires entitlement check but the entitlement app is
invalid. Tethering resource is moved from framework to tethering
module, so Settings can not fetch entitlement app name anymore.

In this change, tethering module would check whether entitltement app
package name is exsited if entitlement check is needed. Tethering would
be not supported (Settings tethering option would be hidded) if
entitlement app is not installed.

After moving the protection into tethering module,
TetherUtil#isProvisioningNeeded is no longer needed. Because The
only use case is Settings wants to gray out tethering setting
when entitltement check is needed but entitlement app is invalid.

c55e229dcb Revert "Revert "Pass entitlement configuration to Settings for entitlement check""
Add commit message here for reference:
Tethering resource configuration is move from framework to tethering
module. The resource would not be accessible from outside of tethering
module.
List the replacements of framework resources usage and intent extra:
1. R.string.config_mobile_hotspot_provision_response
    --> android.net.extra.TETHER_PROVISIONING_RESPONSE.
2. R.string.config_mobile_hotspot_provision_app_no_ui
    --> android.net.extra.TETHER_UI_PROVISIONING_APP_NAME
3. R.array.config_mobile_hotspot_provision_app
    --> android.net.extra.TETHER_SILENT_PROVISIONING_ACTION
Besides, the current active subId would put in
android.net.extra.TETHER_SUBID

Note: They are not APIs because of API freeze. Now both tethering module
and Settings define these strings independently.

This reverts commit 9988903174.

Reason for revert: Resume the CL and put this CL with settings part in the same topic to avoid break.

Original CL has dependencies with unmerged settings change: https://googleplex-android-review.git.corp.google.com/c/platform/packages/apps/Settings/+/11524847
They should be in the same topic, revert it first. Will resume it and put the same with settings part CL.

This reverts commit 217d7b01f8.

Reason for revert: This break hotspot because it should merged with settings part together.

217d7b01f8 Pass entitlement configuration to Settings for entitlement check
Tethering resource configuration is move from framwork to tethering
module. Since tethering resource would not be accessible from outside
of tethering module, EntitlementManager would tell Settings the
entitlement configuration via intent extra when run entitlement check.

5a07338239 Make tether settings intent explicit
Currently tethering notification is sending a pending intent for
redirecting user to tether settings page. However, this intent
is implicit that only create with
Settings.ACTION_TETHER_SETTINGS. For security reasons, this
intetnt should specify an explicit component to be delivered to.
Thus, specify the settings package name to this intent.

7c538fa7ff [BOT.6] Make BpfCoordinator to support data limit
The BPF tethering coordinator listens to the forwarding rule
changes for updating data limit which is applied in the following
conditions.
- After adding the first rule on a given upstream, add data limit.
- After removing the last rule on a given upstream, clear data limit.
- The service applies a new data limit on current upstream.

The reason for relying on rule changes is because the Tethering and
IpServer objects have multi-internal state machines. It is hard to
synchronize all of their states.

Note that the data limit cleanup for stopping or switching upstream
relies on offload rules are all removed as well.

2ecd333f59 Tethering: ensure downstream prefix do not conflict with upstream
- Add New class PrivateAddressCoordinator to coordinate the private
  address conflict problem.
- Downstream prefix would be random in 192.168.0.0/24 ~
  192.168.255.0/24.
- If new upstream prefix is conflict with existing downstream prefix,
  downstream would be kicked out and it would request a new one.
- The last conflict upstream prefixes would be blacklist. Avoid to
select downstream prefix which is conflict with prefixes in blacklist.

Fix TetheringServiceTest test WRITE_SETTINGS permission failure

AdoptShellPermissionIdentity can not pass permission check by
Settings#checkAndNoteWriteSettingsOperation. It would compare the caller
uid and its package name. See error below:
1. java.lang.SecurityException:
Specified package com.android.shell under uid 10239 but it is really 2000
2. java.lang.SecurityException:
uid 10245 does not have android.permission.UPDATE_APP_OPS_STATS.

Override the method and test if caller hold WRITE_SETTINGS directly.

6f532ba30f Don't crash when receiving an RTM_DELNEIGH or NUD_FAILED.
These events don't have MAC addresses, so the code attempts to
create an Ipv6ForwardingRule with a null MAC address. This
crashes when attempting to get the raw MAC address bytes to send
to netd in the TetherOffloadRuleParcel.

This was not caught by unit tests because the test exercise this
code path in a way that is not correct (by sending RTM_DELNEIGH
and NUD_FAILED events with MAC addresses). Fix the unit tests to
properly pass in null MAC addresses for these events.

bd8d7a8208 Fix EntitlementManager issues
1. Add TETHERING_ETHERNET to vaild downstream type. So starting
   ethernet tethering will do entitlement check as well.
2. Ignore request with invalid downstream type on
   handleRequestLatestTetheringEntitlementValue()
