Merge "Remove logic from NetworkMonitorManager wrapper"
Remi NGUYEN VAN   authored and   Gerrit Code Review   commited 2022-06-01 01:20:03 +00:00
de9818fb81
Remove logic from NetworkMonitorManager wrapper
NetworkMonitorManager should just be a passthrough wrapper for
INetworkMonitor. Move logic to choose the notifyNetworkConnected version
to call to its only caller, ConnectivityService.

This allows removing the dependency on modules-utils-build, which makes
the networkstack-client library less portable; for example it would add
duplicate classes if networkstack-client is included into service-wifi,
as service-wifi can already use modules-utils-build from framework-wifi.

move netd maps and progs into /sys/fs/bpf/netd_shared/...
(out of current /sys/fs/bpf/net_shared/...)

This will allow genfscon regexp changes in a followup selinux commit.

Note that this has a hard dependency on system/bpf change
  'bpfloader: add support for netd_shared and net_private subdirs'
which also bumps bpfloader to v0.13.

This was merged May 12, 2022 (into both aosp/master and tm-dev)
and it is in Android T starting with Beta 3 release.

This isn't really an issue since amusingly T Beta 2 is already
incompatible with current mainline releases due to the snap
reverting a previous required bpfloader system/bpf change:
  move net_shared bpf programs into net_shared subdirectory
See: http://b/232050459#comment14

So this doesn't break T Beta1/2, since they already don't work,
and Beta3 will work.

  Check carrier privilege for CBS network requests synchronously

Paul Hu   authored and   Gerrit Code Review   commited 2022-05-10 14:38:30 +00:00

Check carrier privilege for CBS network requests synchronously
Normally if an app calls requestNetwork with capabilities that it
does not have permission to request, it gets a SecurityException,
except if it requests NET_CAPABILITY_CBS, in which case the request
will not throw but the app will get an onUnavailable callback.

Make this codepath throw as well. This simplifies the code and makes
the app-visible behaviour more consistent (and consistent with what
happens in S and below). The reason the code was written this way is because the carrier privilege app should receive a callback if it
loses permission. But onUnavailable is also not the best callback to
send, since it is used very rarely and also releases the app's
request. It seems better to leave the request registered and send
onLost.

Allow 3p apps to request restricted networks
Since 3p apps are allowed to use restricted networks in S, they
should be allowed to request a restricted network reasonably.
Otherwise, the functionalities of 3p apps will break if they rely
on restricted networks. Thus, CS needs to allow 3p apps to
request restricted networks if 3p apps are in the allowed list.

Add a NetworkAgent API to indicate that a network will be replaced.
This is useful for link layers that disconnect but know they will
reconnect to a similar network soon, and do not want the device
to switch to another network until the reconnect happens. An
example is wifi switching to another network that is on a
different subnet without the device switching to cellular data.

This works by immediately destroying the network, so the link
layer can reuse the same interface name for the new network. It
would be possible to delay destroying the network until the new
network connects, but in practice this does not seem useful,
because the if the link layer reuses the interface, then the
interface will be undergoing reconfiguration, and will likely
not be usable for app traffic.

This CL also moves the call to onNetworkDestroyed into
destroyNativeNetwork. This is needed to ensure that the new
API calls onNetworkDestroyed even though most teardown
operations have not happened. This causes onNetworkDestroyed to
happen before the netId is marked free, but that shouldn't cause
any behavioural changes because netId allocation is an
implementation detail of ConnectivityService and is not
observable by apps or system components.
