Extra Bytes in IP Fragmentation


Tag : networking , By : abuiles

around this issue You must fragment the packet payload on eight-byte boundaries. With a 128-byte MTU, the largest payload fragment you can have is 104 bytes, which is smaller than simply subtracting the IP header from the MTU (108 bytes). What the text is telling you that subtracting the packet header size (20 bytes) from the MTU, the next smaller fragment size divisible by eight is 104 bytes.
RFC 791, Internet Protocol has a complete description of how IP fragmentation works:

What's this extra bytes?

wish help you to fix your issue This is the "Rich header". It was added by Microsoft's link.exe (notice the text "Rich" at the end of the block). It's a structure in PE files between the DOS Header and the NT Header (between DOS stub and PE Header). It contains version information of linked libraries and the linkers versions.

What are the extra bytes in the ZipEntry used for?

To fix the issue you can do The answer can be found in the first two links in the java.util.zip package documentation.
The basic zip format is described in the PKWARE zip specification. Sections 4.5 and 4.6 describe what the extra data is.
ByteBuffer extraData = ByteBuffer.wrap(zipEntry.getExtra());
extraData.order(ByteOrder.LITTLE_ENDIAN);

while (extraData.hasRemaining()) {
    int id = extraData.getShort() & 0xffff;
    int length = extraData.getShort() & 0xffff;

    if (id == 0x756e) {
        int crc32 = extraData.getInt();
        short permissions = extraData.getShort();
        int linkLengthOrDeviceNumbers = extraData.getInt();
        int userID = extraData.getChar();
        int groupID = extraData.getChar();

        ByteBuffer linkDestBuffer = extraData.slice().limit(length - 14);
        String linkDestination =
            StandardCharsets.UTF_8.decode(linkDestBuffer).toString();

        // ...
    } else {
        extraData.position(extraData.position() + length);
    }
}
