Not all ESP crypto algorithms require padding/alignment to be the same
as AES block/IV size. CCM, CTR and GCM all have no padding/alignment
requirements, and the RFCs indicate that no padding (beyond ESPs 4 octet
alignment requirement) should be used unless TFC (traffic flow
confidentiality) has been requested.
CTR: https://tools.ietf.org/html/rfc3686#section-3.2
GCM: https://tools.ietf.org/html/rfc4106#section-3.2
CCM: https://tools.ietf.org/html/rfc4309#section-3.2
- VPP is incorrectly using the IV/AES block size to pad CTR and GCM.
These modes do not require padding (beyond ESPs 4 octet requirement), as
a result packets will have unnecessary padding, which will waste
bandwidth at least and possibly fail certain network configurations that
have finely tuned MTU configurations at worst.
Fix this as well as changing the field names from ".*block_size" to
".*block_align" to better represent their actual (and only) use. Rename
"block_sz" in esp_encrypt to "esp_align" and set it correctly as well.
test: ipsec: Add unit-test to test for RFC correct padding/alignment
test: patch scapy to not incorrectly pad ccm, ctr, gcm modes as well
- Scapy is also incorrectly using the AES block size of 16 to pad CCM,
CTR, and GCM cipher modes. A bug report has been opened with the
and acknowledged with the upstream scapy project as well:

Type: improvement
- inline some common encap fixup functions into the midchain
rewrite node so we don't incur the cost of the virtual function call
- change the copy 'guess' from ethernet_header (which will never happen) to an ip4 header
- add adj-midchain-tx to multiarch sources
- don't run adj-midchain-tx as a feature, instead put this node as the
adj's next and at the end of the feature arc.
- cache the feature arc config index (to save the cache miss going to fetch it)
- don't check if features are enabled when taking the arc (since we know they are)
the last two changes will also benefit normal adjacencies taking the arc (i.e. for NAT, ACLs, etc)
for IPSec:
- don't run esp_encrypt as a feature, instead when required insert this
node into the adj's next and into the end of the feature arc. this
implies that encrypt is always 'the last feature' run, which is
symmetric with decrypt always being the first.
- esp_encrpyt for tunnels has adj-midchain-tx as next node

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.

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.

When adding an IPsec SA, ipsec_check_support_cb() is called. This
invokes a callback for AH and a callback for ESP to check if the
algorithms are supported.
When using AES-GCM on an ESP SA with the DPDK IPsec backend selected,
the AH callback fails. The DPDK IPsec backend has no AH support,
so the callback for the default OpenSSL backend is invoked. This
checks whether the crypto algorithm is AES-GCM and returns failure.
Only invoke the callback to check support for the IPsec protocol
of the SA - either AH or ESP rather than doing both.

ipsec4-output and ipsec6-output were conflicting with ipsec
interface names ("ipsec<id>") and vnet/interface.c autogenerated
output node ("<ifname>-output").
Changing feature names seems to be the less invasive option.
This patch also changes "input" feature names for consistency.

Make it easier to integrate with external IKE daemon.
IPsec interfaces can have one or both SAs replaced after
creation. This allows for the possibility of setting a
new child SA on an interface when rekeying occurs. It also
allows for the possibility of creating an interface ahead
of time and updating the SA when parameters that are
negotiated during IKE exchange become known.

- Global variables declared in header files without
the use of the 'extern' keword will result in multiple
instances of the variable to be created by the compiler
-- one for each different source file in which the
the header file is included. This results in wasted
memory allocated in the BSS segments as well as
potentially introducing bugs in the application.
