/**
 * Tag socket referenced by {@code ifd} with {@code tag} for UID {@code uid}.

 * Assumes thread UID tag isn't set upon entry, and ensures thread UID tag isn't set upon exit.
 * Unfortunately there is no TrafficStatis.getThreadStatsUid().

    // descriptor is via ParcelFileDescriptor.adoptFd(). Unfortunately prior to Android
    // Marshmallow ParcelFileDescriptor.detachFd() didn't actually detach from the
    // FileDescriptor, so use reflection to set {@code fd} into the FileDescriptor for
    // versions prior to Marshmallow. Here's the fix that went into Marshmallow:
    // https://android.googlesource.com/platform/frameworks/base/+/b30ad6f

        pfd = null;

    } else {
        pfd = ParcelFileDescriptor.adoptFd(ifd);

    }
    // Second, convert FileDescriptor to Socket.
    Socket s = new SocketFd(fd);
    // Third, tag the Socket.
    TrafficStats.tagSocket(s);
    s.close(); // No-op but always good to close() Closeables.
    // Have ParcelFileDescriptor relinquish ownership of the file descriptor.
