Modularizes the generation of initialization vectors, which allows to use
different methods depending on the algorithms. For instance for AES-GCM
sequential IVs are now used instead of the earlier random IVs, which are
still used for other algorithms e.g. AES-CBC.
Depending on the value of the CVPN3000-IPSec-Split-Tunneling-Policy(55)
radius attribute, the subnets in the CVPN3000-IPSec-Split-Tunnel-List(27)
attribute are sent in either a UNITY_SPLIT_INCLUDE (if the value is 1)
or a UNITY_LOCAL_LAN (if the value is 2).
So if the following attributes would be configured for a RADIUS user
CVPN3000-IPSec-Split-Tunnel-List := "10.0.1.0/255.255.255.0,10.0.2.0/255.255.255.0"
CVPN3000-IPSec-Split-Tunneling-Policy := 1
A UNITY_SPLIT_INCLUDE configuration payload containing these two subnets
would be sent to the client during the ModeCfg exchange.
The contents of the CVPN3000-IPSec-Default-Domain(28) and
CVPN3000-IPSec-Split-DNS-Names(29) radius attributes are forwarded in
the corresponding Unity configuration attributes.
Allows setting a mark on outbound packets and the routing rule
installed by charon. With those settings it is possible to setup
tunnels with kernel-libipsec where the remote peer is part of the remote
traffic selector.
The following example settings in strongswan.conf show how this can be
configured:
charon {
plugins {
kernel-netlink {
fwmark = !0x42
}
socket-default {
fwmark = 0x42
}
kernel-libipsec {
allow_peer_ts = yes
}
}
}
To make it work it is necessary to set
net.ipv4.conf.all.rp_filter
appropriately, otherwise the kernel drops the packets.
References #380.
This actually broke rekeying due to the DROP policies that are
temporarily added, which broke the refcount as the ignored policies
were not ignored in del_policy() (the type is not known there).
Setting the fwmark options for the kernel-netlink and socket-default
plugins allow this kind of setup.
It is probably required to set net.ipv4.conf.all.rp_filter to 2 to make
it work.
This adds support for transactions to the database_t interface and the two
current implementations.
The pool utility is also moved to its own directory in src/.
If the same identity is added concurrently by two threads (or by the
pool utility) INSERT might fail even though the SELECT was unsuccessful
before.
We are currently not able to lock the identities table in a portable way
(something like SELECT ... FOR UPDATE on MySQL).
There could, of course, be race conditions when enumerating the attributes,
but those probably don't matter (e.g. missing an attribute that was
concurrently added).
Transactions are more intended to revert multiple changes if anything
fails in the process.
Enabling FIPS mode twice will fail, so if it is enabled in openssl.conf
it should be disabled in strongswan.conf (or the other way around).
Either way, we should log whether FIPS mode is enabled or not.
References #412.
A new connection ID allows listeners to track which errors they have
already shown to the user or were already dismissed by the user.
This was necessary because the state fragment is now unregistered from
state changes when it is not shown.
Besides that updates don't make much sense when the fragments are not
displayed this fixes the following exception:
java.lang.IllegalStateException: Can not perform this action after
onSaveInstanceState
This is especially useful on Android where we are able to send messages
even if we don't know the correct local address (this is possible
because we don't set source addresses in outbound messages). This way
we may learn the correct local address if it e.g. changed right before
reestablishing an SA.
Updating the local address later is tricky without MOBIKE as the
responder might not update the associated IPsec SAs properly.
Adds support to pki --pub to convert public keys to other formats
including SSH keys and DNSKEYs. SSH public keys can also be read
from files in the format used by OpenSSH.
This adds man pages for all pki sub-commands and promotes pki to a
regular program installed in $prefix/bin.
The usage output of several commands was fixed too.
Can be opened either with "man ipsec pki" or "man ipsec-pki".
Since man(1) only supports one level of subpages, the forthcoming man
pages for each command will have to be opened with "man pki --<command>".
Since comments in resolv.conf are only valid at the beginning of a line
resolvconf(8) seems to have started treating any text after
'nameserver <ip>' as additional IP addresses for name servers.
Since it ignores comments, and we can easily remove the added servers
again, there is no point to add any.
Fixes#410.
The flag is required to convince libtool on Cygwin to build DLLs. But on
Windows these shared libraries can not have undefined symbols, so we have to
link them explicitly to the libraries they reference.
For plugins this is currently not done, so only the monolithic build is
supported. The plugin loader wouldn't be able to load DLLs anyway, as
it tries to load files that don't exist on Cygwin.
