Convert BpfMap native methods to use @FastNative to reduce JNI overhead.
Refactor synchronizeKernelRCU() to be @CriticalNative for maximum
performance by changing its error handling to return an error code
instead of throwing directly from native code.
(In practice we don't expect it to *ever* fail)
FYI:
@FastNative and @CriticalNative are Android-specific annotations
that signal to the ART runtime to use a lower-overhead JNI transition,
resulting in better performance.
A standard JNI call tells the Garbage Collector (GC) that the thread
is transitioning to a 'Native' state. This is a signal to the GC that
the thread might be busy for a while and shouldn't be suspended arbitrarily.
@FastNative is for short, quick functions:
This provides a moderately faster JNI call (thread is still 'Runnable').
The native function signature remains the same as a standard JNI method,
and it can still access the JNIEnv* to interact with Java objects
or throw exceptions.
@CriticalNative is for short, quick & trivial functions:
This provides the fastest possible JNI transition and is intended
for simple, performance-critical leaf functions.
It comes with strict requirements:
- The native method cannot throw exceptions, create Java objects,
or make any other JNI calls.
- All arguments and the return type must be primitive, ie:
jboolean [bool]
jbyte [s8]
jchar [u16]
jshort [s16]
jint [s32]
jlong [s64]
jfloat [32-bit]
jdouble [64-bit]
void
Java objects like String or byte[] are not allowed.
Because of these restrictions, the native C++ function signature
must not include JNIEnv* or jobject/jclass parameters.
(This likely also means it must be 'static')

RoutingCoordinatorService's {add,remove,update}Route methods
all end up calling netd's *RouteParcel methods.
Make callers explicitly generate and pass in the parcel to the
manager class instead of having them pass in a RouteInfo and
having the service class convert the RouteInfo to a parcel.
Also remove the {add,remove,update}Route methods from
RoutingCoordinatorManager since they are unused.
This is a no-op refactor that simplifies upcoming changes.
RoutingCoordinator is not a stable interface and is not used
across the platform/mainline boundary, so there are no version
skew considerations.

The `SYS_CLASS_NET_PATH` constant lacked a trailing slash, which
hindered the correct construction of paths for interface-specific
files (e.g., `/sys/class/net/<interface>/mtu`).
This change adds the missing trailing slash, enabling `ProcfsUtils`
to correctly retrieve interface MTU values and other interface-specific
details from `/sys/class/net`.

Improve the APF test by changing the packet count assertion from
`== 1` to `> matched_pkt_count_before_test`.
This handles scenarios where the packet counter might already
have a non-zero value or increment due to other traffic, making
the test more reliable. The test now asserts that the specific
test packet caused the counter to increase.

The ByteOrder should be encoded by the field, not by the writeToBytes()
method. To fix this, a LegacyStruct is introduced which continues to
expose writeToBytes(ByteOrder) during the transition. This approach
helpfully creates a compile error when converting a Struct class back to
inheriting from Struct for all call sites of writeToBytes(ByteOrder).

The `expect_with_retry` utility expects the lambda to return a
boolean value. However, the previous implementation wrapped the
comparison result `apf_utils.get_matched_packet_counts(...) == 1`
inside a set `{...}`.
This caused the lambda to return a set (e.g., `{True}` or `{False}`),
which is truthy if non-empty, but not the actual boolean result.
This commit removes the unnecessary set wrapper, ensuring the lambda
directly returns the boolean outcome of the packet count comparison

Log.wtf implies a catastrophic, unrecoverable failure. Failures to read
procfs files (e.g., due to permissions or non-existence) are better
represented by Log.e as they are often recoverable or expected under

Previously, IPv4 and IPv6 addresses were retrieved in `ApfTestBase.setup_class`,
which meant all APF tests assumed the presence of both.
This change refactors `ApfTestBase` to introduce dedicated methods:
- `get_and_expect_ipv4_addresses_exist()`
- `get_and_expect_ipv6_addresses_exist()`
These methods now handle the retrieval and assertion of IP addresses.
Individual test cases in `ApfV6Test` are updated to call these methods
only when the respective address type is required for the specific test
scenario.
This improves test robustness by ensuring tests only depend on the
necessary IP addresses, allowing for more precise test setup and failure
reporting. Additionally, the doze mode activation is reordered to occur
after initial network setup.

This refactoring changes how the bluetoothUseRandomAddress flag is
accessed.
PrivateAddressCoordinator is in a library used by multiple mainline
modules(Tethering, NetworkStack, CaptivePortal, WiFi) and cannot
directly read a Tethering mainline beta flag.
To fix this, the flag's value is now passed down through constructors.
An alternative solution would be to split the Java library for each module,
but with this solution, a single utility class cannot be shared.
This commit is a no-op as the passed value is hardcoded to false.
