Improvements to the VICI Perl bindings by Andreas Hofmeister
- Switch.pm, which was implemented as a source filter, has been deprecated in
Perl 5.10 and was later removed from the core modules in Perl 5.14 or so.
Unfortunately, its replacement, the given/when/default construct, has since
been downgraded to "experimental" status because of problems with the underlying
"smart-match" operator.
Thus, as of Perl 5.22, Perl still has no actually usable "switch"-like construct.
So just use boring, old and ugly "if/elsif/else" constructs instead, which are
compatible with almost any Perl version.
- None of the Perl modules here does anything that would require "AutoLoader".
- "Exporter" can be used to export plain functions into another modules name
space. But the things that were exported here are meant to be called as
methods. In this case, it is neither necessary nor advisable to export those
symbols.
Just export nothing (the POD documentation already said so).
- It is usually the calling script that enables (or does not enable) warnings
globally. When a module says "use warnings;" however, the caller looses control
over what warnings should be enabled in that module.

128 bit default security strength for IKE and ESP algorithms
The default ESP cipher suite is now
AES_CBC-128/HMAC_SHA2_256_128
and requires SHA-2 HMAC support in the Linux kernel (correctly implemented
since 2.6.33).
The default IKE cipher suite is now
AES_CBC-128/HMAC_SHA2_256_128/PRF_HMAC_SHA2_256/ECP_256
if the openssl plugin is loaded or
AES_CBC-128/HMAC_SHA2_256_128/PRF_HMAC_SHA2_256/MODP_3072
if ECC is not available.
The use of the SHA-1 hash algorithm and the MODP_2048 DH group has been
deprecated and ENCR_CHACHA20_POLY1305 has been added to the default
IKE AEAD algorithms.

travis: Enable IPv6 on build hosts
Since the move to Google Compute Engine (GCE) IPv6 has been disabled
on the build hosts, causing several tests to fail. Lets try to get at
least local IPv6 connectivity up again.

Standardized printing of certificate information
The certificate_printer class allows the printing of certificate
information to a text file (usually stdout). This class is used
by the pki --print and swanctl --list-certs commands as well as
by the stroke plugin.

vici: Honor an optionally passed IKE configuration name in initiate/install
If two IKE configurations have CHILD configurations with the same name,
we have no control about the CHILD_SA that actually gets controlled. The
new "ike" parameter specifies the peer config name to find the "child" config
under.

vici: Support completely asynchronous initiating and termination
In some situations the vici client is not interested in waiting for a
timeout at all, so don't register a logging callback if the timeout argument
is negative.

watcher: Check for cancellation if poll() fails with EINTR
With LinuxThreads, poll() is unfortunately no cancellation point. It seems
that poll gets woken up after cancellation, but we actively must check
for cancellation before re-entering poll to properly shut down the watcher
thread.

mode-config: Reassign migrated virtual IP if client requests %any
If we mistakenly detect a new IKE_SA as a reauthentication the client
won't request the previous virtual IP, but since we already migrated
it we already triggered the assign_vips() hook, so we should reassign
the migrated virtual IP.

revocation: Allow CRLs to be encoded in PEM format
Since the textual representation for a CRL is now standardized
in RFC 7468 one could argue that we should accept that too, even
though RFC 5280 explicitly demands CRLs fetched via HTTP/FTP to
be in DER format. But in particular for file URIs enforcing that
seems inconvenient.

Merge branch 'eap-mschapv2-eap-identity'
This replaces the EAP-Identity with the EAP-MSCHAPv2 username, which
ensures the client is known with an authenticated identity. Previously
a client with a valid username could use a different identity (e.g. the
name of a different user) in the EAP-Identity exchange. Since we use
the EAP-Identity for uniqueness checks etc. this could be problematic.
The EAP-MSCHAPv2 username is now explicitly logged if it is different
from the EAP-Identity (or IKE identity).
