Examples with PacketSocketAddress android.system.PacketSocketAddress used on opensource projects

Example 1 with PacketSocketAddress

use of android.system.PacketSocketAddress in project platform_frameworks_base by android.

the class ApfFilter method maybeStartFilter.

/**
     * Attempt to start listening for RAs and, if RAs are received, generating and installing
     * filters to ignore useless RAs.
     */
@VisibleForTesting
void maybeStartFilter() {
    FileDescriptor socket;
    try {
        mHardwareAddress = mNetworkInterface.getHardwareAddress();
        synchronized (this) {
            // Install basic filters
            installNewProgramLocked();
        }
        socket = Os.socket(AF_PACKET, SOCK_RAW, ETH_P_IPV6);
        PacketSocketAddress addr = new PacketSocketAddress((short) ETH_P_IPV6, mNetworkInterface.getIndex());
        Os.bind(socket, addr);
        NetworkUtils.attachRaFilter(socket, mApfCapabilities.apfPacketFormat);
    } catch (SocketException | ErrnoException e) {
