2019-05-03svm: basic support for fifo shrinkingFlorin Coras3-78/+663
As opposed to growing, this is not a bulk operation, instead dependent on how the producer/consumer advance head and tail, the fifo will shrink in one or multiple steps. Only once the fifo's nitems and size are reduced to their appropriate values, equal or larger to what was requested, can the fifo chunks be collected by the owner. Chunk collection must be done with the segment heap pushed. Change-Id: Iae407ccf48d85320aa3c1e0304df56c5972c88c1 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-05-03svm: store normalized head/tail for fifoFlorin Coras3-53/+48
If head/tail are stored as "absolute" values that are normalized to [0, fifo_size] interval, when fifo is shrunk/grown the consumer and producer have to independently update to the new fifo size and fix head and tail, respectively. If the head and tail are stored as normalized values, under the right conditions, they don't need to be fixed when fifo size changes. This reverts one of the changes in gerrit 18223.

2019-04-30crypto: enforce per-alg crypto key lengthBenoît Ganne4-18/+57
Crypto algorithms have different requirements on key length. As we do not support key stretching (eg. PBKDF2), user must provide the exact key length used by the algorithm. Failing that means low-level crypto functions might read garbage (eg. aes128_key_expand() will read 16-bytes, regardless of the key provided by the user).

2019-04-26nat: fix ED mode unknown proto session managementMatthew Smith3-8/+24
In endpoint dependent mode, when a session at the head of a user LRU is reused, if the IP protocol for that session was unknown (any other than tcp, udp, or icmp), the attempt to delete the session mapping from the in2out bihash was not using the same key that was used when the mapping was added. This would cause the deletion of the mapping to fail. If packets arrive later which match the original session, the search for the session key would succeed when it should have failed and the session, which is now associated with a different pair of endpoints, may end up being updated when it should not be. Update the key generation when reallocating an existing session to do the right thing if the session is for an unknown protocol. Also update format_nat_session() for unknown protocols so that 'vppctl show nat44 session detail' will display the protocol correctly. In endpoint dependent mode, the IP protocol is stored in the port field on a session if the protocol is unknown. The value is stored in host byte order, but the format function was swapping the bytes before writing the protocol.
