Also assign online leases to a peer connecting from the same endpoint
when it requests any virtual IP. This is mainly a workaround for
Windows clients that remember the virtual IPv6 address and re-request it
the next time the connection is initiated (even if it is not a
reauthentication) but don't do the same for virtual IPv4 addresses.
This can result in duplicate policies with different reqids because
these are allocated for unique sets of traffic selectors.
Fixes#3541.
This allows more fine grained control over what's updated and does not
require multiple calls of the method. Plus we'll be able to use it in
the ike-mobike task.
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.
Load CA certificate id mapping from config and pass the correct CA ID to
TKM when checking certificate chains. The mapping of CA certificate to
CA ID is done via SHA-1 hash of the CA certificates subjectPublicKey.
Debian, Ubuntu, Fedora et. al. started to apply usrmerge to their
latest Linux distributions, i.e. /bin, /sbin, and /lib are now
symbolical links to /usr/bin, /usr/sbin, and /usr/lib, respectively.
Since executables and libraries are contained only once in Linux
packages (e.g. /bin/cp in coreutils but not /usr/bin/cp) this leads
to missing file measurments due to the symlinks when doing remote
attestation.
The new ita_attr_symlinks PA-TNC attribute fixes this problem by
collecting symbolic links pointing to directories on the client
platform.
Depending on from where bison is called, the file might not end up in
the same directory as the .y file, but the location of the Makefile.
This has been seen on FreeBSD.
There is a conflict between Flex's bison-bridge and Bison's api.prefix
options. Apparently, the former was added without consulting the Bison
devs and requires YYSTYPE, which is not added to the header anymore by
the latter. Instead, we just provide the proper definition of yyflex()
manually (as recommended by the Bison docs), so the option is not
required anymore.
DESTROY_IF() checks if the given value is not NULL, before calling
destroy() on it, which does not work for sub-structs. If
port_filter_attr is NULL, this could crash.
If we are already deleting the old/redundant CHILD_SA, we must not
migrate the child-create task as that would destroy the new CHILD_SA we
already moved to the IKE_SA.
Fixes#3644.
Without threads handling the resolution, there is no point waiting
for a reply. If no subsequent resolution successfully starts a
thread (there might not even be one), we'd wait indefinitely.
Fixes#3634.
The DN is otherwise not parsed until compared/printed. This avoids
false detections as ASN.1 DN if e.g. an email address starts with "0",
which is 0x30 = ASN.1 sequence tag, and the next character denotes
the exact length of the rest of the string (see the unit tests for an
example).
For apps targeting Android 10, where a method to change this was added, the
default changed so that all VPN connections are marked as metered. This means
certain background operations (e.g. syncing data) are not performed anymore
even when connected to a WiFi. By setting this to false, the metered state
of the VPN connection reflects that of the underlying networks.
None of our build environments seem to require these declarations. And
current versions of MinGW-w64 define them as inline functions in stdio.h
so these declarations clashed with that ("static declaration of '...'
follows non-static declaration").
If no callback is specified, terminate_ike_execute() is invoked without the
listener waiting on the IKE state change.
Now, if 'force' is false, then ike_sa->delete() just queues an
IKE_DELETE task, and returns SUCCESS - indicating successful task
manager initiation.
However, terminate_ike_execute() ignored this success and set the
status to FAILED.
This is not ideal, as it will be the overall return code of
terminate_ike(), although no failure did occur. This eventually leads
vici's "terminate" to return "Command failed: terminating SA failed",
as seen in this example:
In [9]: list(session.terminate({'ike-id': 2960, 'timeout': -1}))
---------------------------------------------------------------------------
CommandException Traceback (most recent call last)
<ipython-input-9-5f95b5cea88f> in <module>()
----> 1 list(session.terminate({'ike-id': 2960, 'timeout': -1}))
vici/session.pyc in streamed_request(self, command, event_stream_type, message)
136 raise CommandException(
137 "Command failed: {errmsg}".format(
--> 138 errmsg=command_response["errmsg"]
139 )
140 )
CommandException: Command failed: terminating SA failed
If we consider both queueing the task and actually destroying the IKS_SA
a success, we can just always return SUCCESS if we don't have a
callback. There is also no need to explicitly set the status to FAILED
if a listener is waiting as that's the default anyway.

In FIPS mode, libgcrypt uses a DRBG, which behaves differently when the
length passed to gcry_create_nonce() or gcry_randomize() is <= 0. It
expects a struct and explicitly checks that the passed pointer is not
NULL.
This ensures that e.g. ike/child-updown messages are sent that were
queued but couldn't be sent (even the job to enable to on_write() callback
requires a worker thread that's not around anymore during shutdown).
References #3602.
The message_t object used for defragmentation was only cleared after
all fragments have been received and the message was delivered. So
if we received only some fragments of a retransmitted message, the
fragments of the next message were not processed (message_t returns
INVALID_ARG if the message ID does not match causing the message to
get ignored). This rendered the IKE_SA unusable as the client
obviously never retransmitted the fragments of that previous message
after it received our response.
The parser is quite picky and e.g. doesn't accept UUIDs without dashes.
Even without a specific error, this at least points the users into the
right direction.
Fixes#3583.
If the activity is not active when the service connection is
established and handleIntent() is called, the activity's state is already
saved and any fragment transaction would result in an illegalStateException
due to state loss. We just ignore this and wait for another initiation
attempt (via onNewIntent()).
With the flag set, we basically ignore the resent intent, which is not
ideal if we have not yet actually started another activity. The information
dialog we show first would disappear when closing and reopening the app
or even just rotating it (we hide all dialogs when receiving an intent),
but since the flag was restored, the dialog was not shown again even
when attempting to start other connections.
