| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TrafficStats API are being used for querying realtime network statistics for years. However, on certain devices, some network traffic are produced by hardware components and not be able to seen by kernel counters. Thus, include statistics for those missing network traffic is necessary. Note that the included statistics might be stale since polling newest stats from hardware might impact system health and not suitable for TrafficStats API use cases.

* Enforce permission check in getUidStats functionChenbo Feng2020-04-271-44/+16
| | | | | | | | | | | | | | | | | The NetworkStatsService.getUidStats() currently doesn't have any permission check to make sure unpriviledged apps cannot read the stats of a different uid. It will protentially have security problem since apps with ACCESS_NETWORK_STATS permission can directly calling into NetworkStatsService and bypass the check in TrafficStats. Move the uid check from TrafficStats to NetworkStatsService to fix the problem.

* Annotate @SystemApi with required permissions.Jeff Sharkey2017-06-051-0/+3
| | | | | | | | | | | | | | | | | Most @SystemApi methods should be protected with system (or higher) permissions, so annotate common methods with @RequiresPermission to make automatic verification easier. Verification is really only relevant when calling into system services (where permissions checking can happen on the other side of a Binder call), so annotate managers with the new @SystemService annotation, which is now automatically documented. This is purely a docs change; no logic changes are being made. Test: make -j32 update-api && make -j32 offline-sdk-docs Bug: 62263906 Change-Id: I2554227202d84465676aa4ab0dd336b5c45fc651
* StrictMode to detect untagged network traffic.Jeff Sharkey2017-01-191-0/+18
| | | | | | | | | | | | | | | Network usage is tracked by the kernel at the UID level, which is granular enough for normal apps, but large components (such as the system server) are impossible to debug without adding additional socket tagging to help identify subsystems within a UID. To help ensure that system components tag all their network traffic, this change offers a new StrictMode option to detect and report untagged sockets.

| | | | | | | | | | | | | Granular per-UID network statistics can be used to infer user behavior over time, so they fall under the umbrella of the PACKAGE_USAGE_STATS permission. Since we can't check app-ops based permissions in the kernel, the best we can do is redirect users to the NetworkStatsManager class, which offers a much more robust historical data set.

For now there is only one mounted emulated volume at a time, and it's always the primary storage, so give it the default rootId to keep old Uris working.

* Progress towards dynamic storage support.Jeff Sharkey2015-03-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Storage devices are no longer hard-coded, and instead bubble up from whatever Disk and VolumeBase that vold uncovered, turning into sibling Java objects in MountService. We now treat vold events as the source-of-truth for state, and synchronize our state by asking vold to "reset" whenever we reconnect. We've now moved to a model where all storage devices are mounted in the root mount namespace (user boundaries protected with GIDs), so we no longer need app-to-vold path translation. This also means that zygote only needs to bind mount the user-specific /mnt/user/n/ path onto /storage/self/ to make legacy paths like /sdcard work. This grealy simplifies a lot of system code. Many parts of the platform depend on a primary storage device always being present, so we hack together a stub StorageVolume when vold doesn't have a volume ready yet. StorageVolume isn't really a volume anymore; it's the user-specific view onto a volume, so MountService now filters and builds them based on the calling user. StorageVolume is now immutable, making it easier to reason about. Environment now builds all of its paths dynamically based on active volumes. Adds utility methods to turn int types and flags into user-readable strings for debugging purposes. Remove UMS sharing support for now, since no current devices support it; MTP is the recommended solution going forward because it offers better multi-user support. Simplify unmount logic, since vold will now gladly trigger EJECTING broadcast and kill stubborn processes. Bug: 19993667 Change-Id: I9842280e61974c91bae15d764e386969aedcd338
