2020-02-17misc: fix coverity warningsDave Barach1-1/+1
Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.

2019-12-17ipsec: bind an SA to a workerNeale Ranns10-43/+642
the sequence number increment and the anti-replay window checks must be atomic. Given the vector nature of VPP we can't simply use atomic increments for sequence numbers, since a vector on thread 1 with lower sequence numbers could be 'overtaken' by packets on thread 2 with higher sequence numbers. The anti-replay logic requires a critical section, not just atomics, and we don't want that. So when the SA see the first packet it is bound to that worker all subsequent packets, that arrive on a different worker, are subject to a handoff.

To fix i added the seq num to the per-packet data so it is preserved 2 - The high sequence number was not byte swapped during ESP encrypt. 3 - openssl engine was the only one to return FAIL_DECRYPT for bad GCM the others return BAD_HMAC. removed the former 4 - improved tracing to show the low and high seq numbers 5 - documented the anti-replay window checks 6 - fixed scapy patch for ESN support for GCM 7 - tests for anti-reply (w/ and w/o ESN) for each crypto algo Change-Id: Id65d96b6d1d4dd821b2ab557e87468fff6d70e5b Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-07-19fib: FIB Entry trackingNeale Ranns1-10/+6
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.

2019-07-12ipsec: drop outbound ESP when no crypto alg setMatthew Smith4-5/+162
Type: fix If a tunnel interface has the crypto alg set on the outbound SA to IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface, the attempt to write an ESP trailer on the packet occurs at the wrong offset and the vnet buffer opaque data is corrupted, which can result in a SEGV when a subsequent node attempts to use that data. When an outbound SA is set on a tunnel interface which has no crypto alg set, add a node to the ip{4,6}-output feature arcs which drops all packets leaving that interface instead of adding the node which would try to encrypt the packets.
