caa54ac398 copyright: Update GPLv2 license texts
The COPYRIGHT.GPL file was slightly out-of-sync with the last GPLv2
license from Free Software Foundation, Inc.

The changes are primarily a new address, which required touching almost
all the project files.

Except of that, it is just minor adjustments to formatting, removal of
form-feed characters and referencing "GNU Lesser General Public License"
instead of "GNU Library General Public License".

534c8f24bd Skip tls-crypt unit tests if required crypto mode not supported
Instead of failing the test with an unclear error, print that the a
required crypto primitive is not supported and skip the test.

This is for example the case when using the system-supplied openssl on
SLES11, which does not support AES-256-CTR.

Drop packets instead of assert out if packet id rolls over (CVE-2017-7479)
Previously, if a mode was selected where packet ids are not allowed to roll
over, but renegotiation does not succeed for some reason (e.g. no password
entered in time, certificate expired or a malicious peer that refuses the
renegotiaion on purpose) we would continue to use the old keys.  Until the
packet ID would roll over and we would ASSERT() out.

Given that this can be triggered on purpose by an authenticated peer, this
is a fix for an authenticated remote DoS vulnerability.  An attack is
rather inefficient though; a peer would need to get us to send 2^32
packets (min-size packet is IP+UDP+OPCODE+PID+TAG (no payload), results in
(20+8+1+4+16)*2^32 bytes, or approx. 196 GB).

This is a fix for finding 5.2 from the OSTIF / Quarkslab audit.

a87e1431ba cleanup: merge packet_id_alloc_outgoing() into packet_id_write()
The functions packet_id_alloc_outgoing() and packet_id_write() were
always called in tandem.  Instead of forcing the caller to allocate a
packet_id_net to do so, merge the two functions.  This simplifies the API
and reduces the chance on mistakes in the future.

This patch adds unit tests to verify the behaviour of packet_id_write().
Verifying that we assert out correctly required the change to mock_msg.c.

2dc3322664 Deprecate --ns-cert-type
The nsCertType x509 extension is very old, and barely used.  We already
have had an alternative for a long time: --remote-cert-tls uses the far
more common keyUsage and extendedKeyUsage extensions instead.

OpenSSL 1.1 longer exposes an API to (separately) check the nsCertType x509
extension.  Since we want be able to migrate to OpenSSL 1.1, we should
deprecate this option immediately.

ec4dff3bbd Don't reopen tun if cipher changes
When the pulled options change, OpenVPN will attempt to reopen the tun
device.  That might fail if the process has already dropper privileges,
and is not needed unless the tun MTU is changed.  This patch therefore
ignores the cipher value for the digest if a fixed tun-mtu is used.

Additionally, this patch changes the md_ctx_update() call to include the
trailing zero byte of each option, to make sure that parsing "foo,bar"
results in a different hash than "foobar".  (Sorry for not catching that
during the review...)

The unit tests are a bit lame, but it secretly serves as a way to lower
the bar for adding more buffer.c unit tests.

3b185161de Add --tls-crypt unit tests
These help verify the tls-crypt functionality - they already caught a
bug during development.  We should however probably also add some
t_client tests once this feature is in.

To test --tls-crypt with as few dependencies as possible, this adds a
mock implementation of msg() (or actually x_msg()).  For debugging
purposes, the mock implementation can be made to really log by calling
mock_set_debug_level(), but defaults to (almost) no logging.

8ca29af7c6 make t_client robust against sudoers misconfiguration
Instead of testing (and priming) sudo with "true", prime with
"kill -0 $$" (just test signalling ourselves).  If this fails,
we won't be able to kill the openvpn process we're going to
start later on -> thus, SKIP on failure.

This helps with misconfigured setups (especially on the buildbots)
that can correctly start openvpn but then not stop it later on -
leaving openvpn processes dangling around, requiring manual
intervention.

This will check the OpenVPN log file if the process initialized
successfully.

It will check the log file for 30 seconds before aborting the test run.
This also has the advantage of starting the testing quicker if the
initialization goes faster than 10 seconds (which was the old sleep time).

The umask is also set to a more permissive mode to ensure the test
script is capable of reading the OpenVPN PID file, as that will be
created by root.

If PREFER_KSU is not set or a Kerberos ticket is not found, it
will fallback to the configured RUN_SUDO approach.

so there is also additional code to find the full path of true and kill.

c94b3ff0f5 Discourage using 64-bit block ciphers
As discussed with the development team, we should start moving away from
ciphers with a small block size.  For OpenVPN in particular this means
moving away from 64-bit block ciphers, towards 128-bit block ciphers.
This patch makes a start with that by moving ciphers with a block
size < 128 bits to the bottom of the --show-ciphers output, and printing
a warning in the connection phase if such a cipher is used.

While touching this function, improve the output of --show-ciphers by
ordering the output alphabetically, and changing the output format
slightly.

[DS: Fixed C89 issues in patch, moving 'int nid' and 'size_t i' declaration
     to begining of function instead of in the for-loops.  This is also
     required to not break building on stricter compiler setups where C99
     must be enabled explicitly ]

45f6e7991c Only build and run cmocka unit tests if its submodule is initialized
Commit 40cb4cfc5d added infrastructure to write unit tests using
cmocka.  This was implemented using a git submodule to fetch an
up-to-date cmocka test framework.

The issue which appeared was that 'make check' stopped working if
the cmocka submodule was not initialized and updated.  As we do not
want this to be a hard depenency, this patch makes running these
unit tests conditional.  If cmocka has not been initialized, skip
them or if it has been initialized all unit tests will be run.

 [v2 - Also check if cmake is available, as cmocka depends on that
       to be built ]

4507bb6cd1 Add a test for auth-pam searchandreplace
No functional changes.

Utility functions of auth-pam are split into a dedicated file. This allows
the test programs to easily test these functions without adding
dependencies.

Add a minimal test for searchandreplace as a proof of concept.

40cb4cfc5d Add unit testing support via cmocka
cmocka [1,2] is a testing framework for C. Adding unit test
capabilities to the openvpn repository will greatly ease the
task of writing correct code.

cmocka source code is added as git submodule in ./vendor. A
submodule approach has been chosen over a classical library
dependency because libcmocka is not available, or only
available in very old versions (e.g. on Ubuntu).

cmocka is build during 'make check' and installed in vendor/dist/.

f40f10ea96 Prevent integration test timeout bc. of sudo
Integration tests run by t_client.sh use sudo to run openvpn as root.

If the t_client.sh script is configured to use sudo then the user
must enter the password quickly because t_client assumes a startup
failure if openvpn does not start quick enough.

If the user is not quick enough, then the tests fails.

This change will refresh the sudo timestamp at the start of the script.

Tested on MacOS X & Ubuntu Precise

fc03ca9d13 Enforce "serial-tests" behaviour for tests/Makefile
Our "make check" testsuite creates quite a bit of output which is
intended to help pinpointing the exact reason for failure - hidden by
default by automake 1.12 and up, which default to "parallel-tests" which
has no benefit for us.  So, just set the automake option to revert to
the old behaviour.

98156e90e1 Really fix '--cipher none' regression
... by not incorrectly hinting to the compiler the function argument of
cipher_kt_mode_{cbc,ofb_cfb}() is nonnull, since that no longer is the
case.

Verified the fix on Debian Wheezy, one of the platforms the reporter in
trac #473 mentions with a compiler that would optimize out the required
checks.

Also add a testcase for --cipher none to t_lpback, to prevent further
regressions.

"ip -6 route show" prints stuff like "rtt 38ms rttvar 38ms cwnd 10", which
sometimes changes while an OpenVPN test is running, resulting in spurious
failures in the "ifconfig/route must be restored identically after
OpenVPN ends" test in t_client.sh.  Not all fields are there all the time,
so use "sed" to get rid of whatever is printed this time.

Only relevant for "make check" on linux builds with "--enable-iproute2".
