commit b27055a08ad4b415dcf15b63034f9cb236f7fb40

    net: fix geneve_opt length integer overflow

    struct geneve_opt uses 5 bit length for each single option, which
    means every vary size option should be smaller than 128 bytes.

    However, all current related Netlink policies cannot promise this
    length condition and the attacker can exploit a exact 128-byte size
    option to *fake* a zero length option and confuse the parsing logic,
    further achieve heap out-of-bounds read.

    One example crash log is like below:
