* mptcp: move crypto test to KUNITPaolo Abeni2020-06-271-61/+2
| | | | | | | | | | | | | | currently MPTCP uses a custom hook to executed unit tests at boot time. Let's use the KUNIT framework instead. Additionally move the relevant code to a separate file and export the function needed by the test when self-tests are build as a module.

| * mptcp: use SHA256_BLOCK_SIZE, not SHA_MESSAGE_BYTESEric Biggers2020-05-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for naming the SHA-1 stuff in <linux/cryptohash.h> properly and moving it to a more appropriate header, fix the HMAC-SHA256 code in mptcp_crypto_hmac_sha() to use SHA256_BLOCK_SIZE instead of "SHA_MESSAGE_BYTES" which is actually the SHA-1 block size. (Fortunately these are both 64 bytes, so this wasn't a "real" bug...)

* | mptcp: use untruncated hash in ADD_ADDR HMACTodd Malsbary2020-05-221-15/+9
|/ | | | | | | | | | | | | | | | | There is some ambiguity in the RFC as to whether the ADD_ADDR HMAC is the rightmost 64 bits of the entire hash or of the leftmost 160 bits of the hash. The intention, as clarified with the author of the RFC, is the entire hash. This change returns the entire hash from mptcp_crypto_hmac_sha (instead of only the first 160 bits), and moves any truncation/selection operation on the hash to the caller.

* mptcp: move from sha1 (v0) to sha256 (v1)Paolo Abeni2020-01-241-55/+85
| | | | | | | | | | For simplicity's sake use directly sha256 primitives (and pull them as a required build dep). Add optional, boot-time self-tests for the hmac function.

* mptcp: Add key generation and token treePeter Krystad2020-01-241-0/+122
Generate the local keys, IDSN, and token when creating a new socket. Introduce the token tree to track all tokens in use using a radix tree with the MPTCP token itself as the index. Override the rebuild_header callback in inet_connection_sock_af_ops for creating the local key on a new outgoing connection. Override the init_req callback of tcp_request_sock_ops for creating the local key on a new incoming connection. Will be used to obtain the MPTCP parent socket to handle incoming joins.
