This might be helpful to get the complete picture of the installed
rules. `-c` is currently not used as the counters that are added in
front of every rule make the output quite hard to read and the counters
are already provided in the accompanying `iptables -v -L` output.
Fixes#2111.
The run is aborted after the current scenario. Depending on which
command was interrupted it might be necessary to press CTRL-C multiple
times (e.g. if a later command depends on the interrupted one).
This should fix HTML files and get us some proper console output after
the run.
This avoids having to copy testresults, makes results of cancelled runs
browsable (runs may actually be followed live) and preserves old results
when rebuilding guest images (e.g. when using the build-strongswan script).
The number of consecutive test runs without any intermittent rebuild of the
guest images is also not limited by the image size anymore.
This was only required when we initially started and OpenSSL was built
from sources, which was changed with b97dd59ba841 ("install FIPS-aware
OpenSSL Debian packages").
This reverts commit dee01d019ba9743b2784b417155601d10c173a66.
Thanks to 505c31870162 ("leak-detective: Try to properly free
allocations after deinitialization") this is not required anymore.
The change in c423d0e8a124 ("testing: Fix race in tnc/tnccs-20-pdp-pt-tls
scenario") is not really ideal as now the vici plugin might not yet be
ready when `swanctl --load-creds` is called. Perhaps starting charon
before Apache causes enough delay.
Once we switch to charon-systemd this isn't a problem anymore as starting the
unit will block until everything is up and ready. Also, the individual
swanctl calls will be redundant as the default service unit calls --load-all.
But start scripts do run before charon-systemd signals that the daemon is
ready, so using these would work too then.
The main issue is that the ldap and curl plugins, or rather the libraries
they use, initialize GnuTLS (curl, strangely, even when it is, by its own
account, linked against OpenSSL). Some of these allocations are only freed
once the libraries are unloaded. This means that the leak detective causes
invalid frees when swanctl is terminated and libraries are unloaded after the
leak detective is already deinitialized.
aacf84d837e7 ("testing: Add expect-connection calls for all tests and
hosts") removed the expect-connection call for the non-existing aaa
connection. However, because the credentials were loaded asynchronously
via start-script the clients might have been connecting when the secrets
were not yet loaded. As `swanctl --load-creds` is a synchronous call
this change avoids that issue without having to add a sleep or failing
expect-connection call.
This took a while as in the OpenSSL package shipped with Debian and on which
our FIPS-enabled package is based, the function SSL_export_keying_material(),
which is used by FreeRADIUS to derive the MSK, did not use the correct digest
to calculate the result when TLS 1.2 was used. This caused IKE to fail with
"verification of AUTH payload with EAP MSK failed". The fix was only
backported to jessie recently.
While this is not the latest 2.x release it is the latest in /old.
Upgrading to 3.0 might be possible, not sure if the TNC-FHH patches could
be easily updated, though. Upgrading to 3.1 will definitely not be possible
directly as that version removes the EAP-TNC module. So we'd first have to
get rid of the TNC-FHH stuff.
There is a bug (fix at [1]) in hostapd 2.1-2.3 that let it crash when used
with the wired driver. The package in jessie (and sid) is affected, so we
build it from sources (same, older, version as wpa_supplicant).

Sometimes tcpdump fails to process all packets during the short running
time of a scenario:
0 packets captured
18 packets received by filter
0 packets dropped by kernel
So 18 packets were captured by libpcap but tcpdump did not yet process
and print them.
This tries to use --immediate-mode if supported by tcpdump (the one
currently in jessie or wheezy does not, but the one in jessie-backports
does), which disables the buffering in libpcap.
However, even with immediate mode there are cases where it takes a while
longer for all packets to get processed. And without it we also need a
workaround (even though the version in wheezy actually works fine).
That's why there now is a loop checking for differences in captured vs.
received packets. There are actually cases where these numbers are not
equal but we still captured all packets we're interested in, so we abort
after 1s of retrying. But sometimes it could still happen that packets
we expected got lost somewhere ("packets dropped by kernel" is not
always 0 either).
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.
