In particular for the first one randomization could trigger an additional
rekeying, which let the "Adding ESA ..." check fail. But even without
randomization (could be seen in the second scenario that already uses
`rand_time=0`) 4 seconds can apparently be too low some time.
Verify certificate chains starting from the root CA certificate and
moving towards the leaf/user certificate.
Also update TKM-RPC and TKM in testing scripts to version supporting the
reworked CC handling.
After a rekeying the outbound SA and policy is deleted immediately, however,
the inbound SA is not removed until a few seconds later, so delayed packets
can still be processed.
This adds a flag to get_esa_id() that specifies the location of the
given SPI.
The main difference is that ping now reports icmp_seq instead of
icmp_req, so we match for icmp_.eq, which works with both releases.
tcpdump now also reports port 4500 as ipsec-nat-t.
This test asserts that the handling of XFRM expire messages from the
kernel are handled correctly by the xfrm-proxy and the Esa Event Service
(EES) in charon-tkm.
