- * A NetworkFactory is an entity that creates NetworkAgent objects.
- * The bearers register with ConnectivityService using {@link #register} and
- * their factory will start receiving scored NetworkRequests. NetworkRequests
- * can be filtered 3 ways: by NetworkCapabilities, by score and more complexly by
- * overridden function. All of these can be dynamic - changing NetworkCapabilities
- * or score forces re-evaluation of all current requests.
- *
- * If any requests pass the filter some overrideable functions will be called.
- * If the bearer only cares about very simple start/stopNetwork callbacks, those
- * functions can be overridden. If the bearer needs more interaction, it can
- * override addNetworkRequest and removeNetworkRequest which will give it each
- * request that passes their current filters.
- *
- * This class is mostly a shim which delegates to one of two implementations depending
- * on the SDK level of the device it's running on.

-/**
- * This class encapsulates the mechanics of registering a file descriptor
- * with a thread's Looper and handling read events (and errors).
- *
- * Subclasses MUST implement createFd() and SHOULD override handlePacket(). They MAY override
- * onStop() and onStart().
- *
- * Subclasses can expect a call life-cycle like the following:
- *
- * [1] when a client calls start(), createFd() is called, followed by the onStart() hook if all
- * goes well. Implementations may override onStart() for additional initialization.
- *
- * [2] yield, waiting for read event or error notification:
- *
- * [a] readPacket() && handlePacket()
- *
- * [b] if (no error):
- * goto 2
- * else:
- * goto 3
- *
- * [3] when a client calls stop(), the onStop() hook is called (unless already stopped or never
- * started). Implementations may override onStop() for additional cleanup.
- *
- * The packet receive buffer is recycled on every read call, so subclasses
- * should make any copies they would like inside their handlePacket()
- * implementation.
- *
- * All public methods MUST only be called from the same thread with which
- * the Handler constructor argument is associated.
- *
- * @param <BufferType> the type of the buffer used to read data.

-# JNI
-As a general rule, jarjar every static library dependency used in a mainline module into the
-modules's namespace (especially if it is also used by other modules)
-
-Fully-qualified name of java class needs to be hard-coded into the JNI .so, because JNI_OnLoad
-does not take any parameters. This means that there needs to be a different .so target for each
-post-jarjared package, so for each module.
-
-This is the guideline to provide JNI library shared with modules:
-
-* provide a common java library in frameworks/libs/net with the Java class (e.g. BpfMap.java).
-
-* provide a common native library in frameworks/libs/net with the JNI and provide the native
- register function with class_name parameter. See register_com_android_net_module_util_BpfMap
- function in frameworks/libs/net/common/native/bpfmapjni/com_android_net_module_util_BpfMap.cpp
- as an example.
-
-When you want to use JNI library from frameworks/lib/net:
-
-* Each module includes the java library (e.g. net-utils-device-common-bpf) and applies its jarjar
- rules after build.
-
-* Each module creates a native library in their directory, which statically links against the
- common native library (e.g. libnet_utils_device_common_bpf), and calls the native registered
- function by hardcoding the post-jarjar class_name. Linkage *MUST* be static because common
- functions in the file (e.g., `register_com_android_net_module_util_BpfMap`) will appear in the
- library (`.so`) file, and different versions of the library loaded in the same process by
- different modules will in general have different versions. It's important that each of these
- libraries loads the common function from its own library. Static linkage should guarantee this
- because static linkage resolves symbols at build time, not runtime.

- * Note: these all take pointers to const map because from the C/eBPF point of view
- * the map struct is really just a readonly map definition of the in kernel object.

- * The bpf_{map,prog}_def structures are compiled for different architectures.
- * Once by the BPF compiler for the BPF architecture, and once by a C++
- * compiler for the native Android architecture for the bpfloader.
- *
- * For things to work, their layout must be the same between the two.
- * The BPF architecture is platform independent ('64-bit LSB bpf').
- * So this effectively means these structures must be the same layout
- * on 5 architectures, all of them little endian:
- * 64-bit BPF, x86_64, arm and 32-bit x86 and arm
- *
- * As such for any types we use inside of these structs we must make sure that
- * the size and alignment are the same, so the same amount of padding is used.
- *
- * Currently we only use: bool, enum bpf_map_type and unsigned int.
- * Additionally we use char for padding.
- *
- * !!! WARNING: HERE BE DRAGONS !!!
- *
- * Be particularly careful with 64-bit integers.
- * You will need to manually override their alignment to 8 bytes.
- *
- * To quote some parts of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69560
- *
- * Some types have weaker alignment requirements when they are structure members.
- *
- * unsigned long long on x86 is such a type.
- *
- * C distinguishes C11 _Alignof (the minimum alignment the type is guaranteed
- * to have in all contexts, so 4, see min_align_of_type) from GNU C __alignof
- * (the normal alignment of the type, so 8).
- *
- * alignof / _Alignof == minimum alignment required by target ABI
- * __alignof / __alignof__ == preferred alignment
- *
- * When in a struct, apparently the minimum alignment is used.

-// This file is a snapshot of an AIDL file. Do not edit it manually. There are
-// two cases:
-// 1). this is a frozen version file - do not edit this in any case.
-// 2). this is a 'current' file. If you make a backwards compatible change to
-// the interface (from the latest frozen version), the build system will
-// prompt you to update this file with `m <name>-update-api`.
-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

-/**
- * A class that forwards packets from a {@link TestNetworkInterface} to another
- * {@link TestNetworkInterface} with NAT.
- *
- * For testing purposes, a {@link TestNetworkInterface} provides a {@link FileDescriptor}
- * which allows content injection on the test network. However, this could be hard to use
- * because the callers need to compose IP packets in order to inject content to the
- * test network.
- *
- * In order to remove the need of composing the IP packets, this class forwards IP packets to
- * the {@link FileDescriptor} of another {@link TestNetworkInterface} instance. Thus,
- * the TCP/IP headers could be parsed/composed automatically by the protocol stack of this
- * additional {@link TestNetworkInterface}, while the payload is supplied by the
- * servers run on the interface.
- *
- * To make it work, an internal interface and an external interface are defined, where
- * the client might send packets from the internal interface which are originated from
- * multiple addresses to a server that listens on the external address.
- *
- * When forwarding the outgoing packet on the internal interface, a simple NAT mechanism
- * is implemented during forwarding, which will swap the source and destination,
- * but replacing the source address with the external address,
- * e.g. 192.168.1.1:1234 -> 8.8.8.8:80 will be translated into 8.8.8.8:1234 -> 1.2.3.4:80.
- *
- * For the above example, a client who sends http request will have a hallucination that
- * it is talking to a remote server at 8.8.8.8. Also, the server listens on 1.2.3.4 will
- * have a different hallucination that the request is sent from a remote client at 8.8.8.8,
- * to a local address 1.2.3.4.
- *
- * And a NAT mapping is created at the time when the outgoing packet is forwarded.
- * With a different internal source port, the instance learned that when a response with the
- * destination port 1234, it should forward the packet to the internal address 192.168.1.1.
- *
- * For the incoming packet received from external interface, for example a http response sent
- * from the http server, the same mechanism is applied but in a different direction,
- * where the source and destination will be swapped, and the source address will be replaced
- * with the internal address, which is obtained from the NAT mapping described above.

- * It can be called repeatedly and will return the elements as they arrive.
- *
- * Intended usage looks something like this :
- * val TrackRecord<MyObject> record = ArrayTrackRecord().newReadHead()
- * Thread().start {
- * // do stuff
- * record.add(something)
- * // do stuff
- * }
- *
- * val obj1 = record.poll(timeout)
- * // do something with obj1
- * val obj2 = record.poll(timeout)
- * // do something with obj2
- *
- * The point is that the caller does not have to track the mark like it would have to if
- * it was using ArrayTrackRecord directly.
- *
- * Thread safety :
- * A ReadHead delegates all TrackRecord methods to its associated ArrayTrackRecord, and
- * inherits its thread-safe properties for all the TrackRecord methods.
- *
- * Poll() operates under its own set of rules that only allow execution on multiple threads
- * within constrained boundaries, and never concurrently or pseudo-concurrently. This is
- * because concurrent calls to poll() fundamentally do not make sense. poll() will move
- * the mark according to what events remained to be read by this read head, and therefore
- * if multiple threads were calling poll() concurrently on the same ReadHead, what
- * happens to the mark and the return values could not be useful because there is no way to
- * provide either a guarantee not to skip objects nor a guarantee about the mark position at
- * the exit of poll(). This is even more true in the presence of a predicate to filter
- * returned elements, because one thread might be filtering out the events the other is
- * interested in. For this reason, this class will fail-fast if any concurrent access is
- * detected with ConcurrentAccessException.
- * It is possible to use poll() on different threads as long as the following can be
- * guaranteed : one thread must call poll() for the last time, then execute a write barrier,
- * then the other thread must execute a read barrier before calling poll() for the first time.
- * This allows in particular to call poll in @Before and @After methods in JUnit unit tests,
- * because JUnit will enforce those barriers by creating the testing thread after executing
- * @Before and joining the thread after executing @After.
- *
- * peek() can be used by multiple threads concurrently, but only if no thread is calling
- * poll() outside of the boundaries above. For simplicity, it can be considered that peek()
- * is safe to call only when poll() is safe to call.
- *
- * Polling concurrently from the same ArrayTrackRecord is supported by creating multiple
- * ReadHeads on the same instance of ArrayTrackRecord (or of course by using ArrayTrackRecord
- * directly). Each ReadHead is then guaranteed to see all events always and
- * guarantees are made on the value of the mark upon return. {@see poll(Long, (E) -> Boolean)}
- * for details. Be careful to create each ReadHead on the thread it is meant to be used on, or
- * to have a clear synchronization point between creation and use.
- *
- * Users of a ReadHead can ask for the current position of the mark at any time, on a thread
- * where it's safe to call peek(). This mark can be used later to replay the history of events
- * either on this ReadHead, on the associated ArrayTrackRecord or on another ReadHead
- * associated with the same ArrayTrackRecord. It might look like this in the reader thread :
- *
- * val markAtStart = record.mark
- * // Start processing interesting events
- * while (val element = record.poll(timeout) { it.isInteresting() }) {
- * // Do something with element
- * }
- * // Look for stuff that happened while searching for interesting events
- * val firstElementReceived = record.getOrNull(markAtStart)
- * val firstSpecialElement = record.getOrNull(markAtStart) { it.isSpecial() }
- * // Get the first special element since markAtStart, possibly blocking until one is available
- * val specialElement = record.poll(timeout, markAtStart) { it.isSpecial() }
- */

-/**
- * Utility to do cleanup in tests without replacing exceptions with those from a finally block.
- *
- * This utility is meant for tests that want to do cleanup after they execute their test
- * logic, whether the test fails (and throws) or not.
- *
- * The usual way of doing this is to have a try{}finally{} block and put cleanup in finally{}.
- * However, if any code in finally{} throws, the exception thrown in finally{} is thrown before
- * any thrown in try{} ; that means errors reported from tests are from finally{} even if they
- * have been caused by errors in try{}. This is unhelpful in tests, because it results in a
- * stacktrace for a symptom rather than a stacktrace for a cause.
- *
- * To alleviate this, tests are encouraged to make sure the code in finally{} can't throw, or
- * that the code in try{} can't cause it to fail. This is not always realistic ; not only does
- * it require the developer thinks about complex interactions of code, test code often relies
- * on bricks provided by other teams, not controlled by the team writing the test, which may
- * start throwing with an update (see b/198998862 for an example).
- *
- * This utility allows a different approach : it offers a new construct, tryTest{}cleanup{} similar
- * to try{}finally{}, but that will always throw the first exception that happens. In other words,
- * if only tryTest{} throws or only cleanup{} throws, that exception will be thrown, but contrary
- * to the standard try{}finally{}, if both throws, the construct throws the exception that happened
- * in tryTest{} rather than the one that happened in cleanup{}.
- *
- * Kotlin usage is as try{}finally{}, but with multiple finally{} blocks :
- * tryTest {
- * testing code
- * } cleanupStep {
- * cleanup code 1
- * } cleanupStep {
- * cleanup code 2
- * } cleanup {
- * cleanup code 3
- * }
- * Catch blocks can be added with the following syntax :
- * tryTest {
- * testing code
- * }.catch<ExceptionType> { it ->
- * do something to it
- * }
- *
- * Java doesn't allow this kind of syntax, so instead a function taking lambdas is provided.
- * testAndCleanup(() -> {
- * testing code
- * }, () -> {
- * cleanup code 1
- * }, () -> {
- * cleanup code 2
- * });
