ipsec: fix AES CBC IV generation (CVE-2022-46397)stable/2001
For AES-CBC, the IV must be unpredictable (see NIST SP800-38a Appendix C). Chaining IVs like is done by ipsecmb and native backends for the VNET_CRYPTO_OP_FLAG_INIT_IV is fully predictable. Encrypt a counter as part of the message, making the (predictable) counter-generated IV unpredictable.
