2013-12-19Move some system services to separate directoriesAmith Yamasani
Refactored the directory structure so that services can be optionally excluded. This is step 1. Will be followed by another change that makes it possible to remove services from the build. Change-Id: Ideacedfd34b5e213217ad3ff4ebb21c4a8e73f85
2013-12-06Add address flags and scope to LinkAddress.Lorenzo Colitti
This is necessary so that the framework can know whether an IPv6 address is likely to be usable (i.e., if it's global scope and preferred). Also, it will simplify the address notification methods in INetworkManagementEventObserver, which currently take the address, the flags, and the scope as separate arguments. 1. Add flags and scope to the class and update the unit test. Use the IFA_F_* and RT_SCOPE_* constants defined by libcore. Since most callers don't know about flags and scope, provide constructors that default the flags to zero and determine the scope from the address. Addresses notified by the kernel will have these properly set. Make multicast addresses invalid. Update the class documentation. 2. Provide an isSameAddressAs() method that compares only the address and prefix information between two LinkAddress objects. This is necessary because an interface can't have two addresses with the same address/prefix but different flags. 3. Update LinkProperties's addLinkAddress and removeLinkAddress to identify existing addresses to add/remove using isSameAddressAs instead of implicit equals(). Specifically: - If addLinkAddress is called with an address that is already present, the existing address's flags and scope are updated. This allows, for example, an address on an interface to go from preferred to deprecated when it expires, without it having to be removed and re-added. - If removeLinkAddress is called with an address that is present but with different flags, it deletes that address instead of failing to find a match. 4. Update the INetworkManagementEventObserver address notification methods to take just a LinkAddress instead of LinkAddress, flags, and scope. While I'm at it, change the order of the arguments for consistency with the other functions in the interface. Change-Id: Id8fe0f09a7e8f6bee1ea3b52102178b689a9336e
2013-11-26Use LinkAddress in address notifications.Lorenzo Colitti
Currently address{Updated,Removed} pass in the address as a string such as "fe80::1/64". Use LinkAddresses instead, since that's what it is. This makes the code more robust in the unlikely case that netd passes in an invalid string. In the future we can move flags and scope into the LinkAddress itself and simplify the code further.

2013-11-25Pass DNS server info notifications to observers.Lorenzo Colitti
These are sent if the device receives IPv6 Router Advertisements with DNS server configuration options. Currently, nothing listens to them; in a future change we will use them as IPv6 DNS servers.

2013-09-10Request all tethering interfaces, fix corruption.Jeff Sharkey
netd now tracks statistics for tethered interfaces across tethering sessions, so switch to asking for all tethering stats. (Currently we're double-counting all tethering data, ever since it started tracking across sessions.) Also catch OOME to handle corrupt stats files, which we then dump to DropBox and then start over.

2013-08-23Add a simple test for NetworkManagementService.Lorenzo Colitti
For now, this only tests network observers. It works by starting NetworkManagementService with a fake netd socket, feeding it inputs, and seeing if the appropriate observer methods are called. Bug: 10232006 Change-Id: I827681575642a4ee13ae48b81272521544b676bd
2013-08-20Notify IP address changes to interface observers.Lorenzo Colitti
1. Add addressUpdated and addressRemoved methods to INetworkManagementEventObserver. (The -Updated method is not called -Added because it gets called for both adds and changes.) Update all its callers in the tree. 2. Make NetworkManagementService parse IP address notifications from NetlinkHandler and call the address{Removed,Updated} on its observers.

2013-06-06Accumulate network statistics based on deltas.Jeff Sharkey
Network stats are now read out of the kernel in one sweep, instead of reading per-UID. We now accumulate the delta traffic between each stats snapshot using the well-tested SamplingCounter pattern. Since Wi-Fi and mobile traffic have different costs, track each separately. Avoids counting misc interfaces like loopback and ethernet under total.

2013-03-17Catch RuntimeException in NMService notificationsLorenzo Colitti
Currently, NetworkManagementService only catches RemoteExceptions when calling the BaseNetworkObserver notification methods (e.g., interfaceStatusChanged). However, if the observer is in the same process, unchecked exceptions can occur as well. When this happens, finishBroadcast does not get called, and no further notifications can be sent, because any attempt to do so fails with a "beginBroadcast() called while already in a broadcast" exception. Fix this by catching RuntimeException as well. Bug: 8397534 Bug: 8276725 Change-Id: Icd6f32128707244978943c48a9ea3a2b952a2957

2012-08-27Always-on VPN.Jeff Sharkey
Adds support for always-on VPN profiles, also called "lockdown." When enabled, LockdownVpnTracker manages the netd firewall to prevent unencrypted traffic from leaving the device. It creates narrow rules to only allow traffic to the selected VPN server. When an egress network becomes available, LockdownVpnTracker will try bringing up the VPN connection, and will reconnect if disconnected. ConnectivityService augments any NetworkInfo based on the lockdown VPN status to help apps wait until the VPN is connected. This feature requires that VPN profiles use an IP address for both VPN server and DNS. It also blocks non-default APN access when enabled. Waits for USER_PRESENT after boot to check KeyStore status.
