78e0c5f2f5 sample-keys: renew for the next 10 years
Old expiration was October 2024, less than a year away.
Give everyone the chance to get the new keys before tests
start failing.

227799b834 protocol_dump: tls-crypt support
Add support for tls-crypt packets in protocol_dump(). Currently,
protocol_dump() will print garbage for tls-crypt packets.

This patch makes protocol_dump print the clear text parts of the packet such
as the auth tag and replay packet id. It does not try to print the wKc for
HARD_RESET_CLIENT_V3 or CONTROL_WKC_V1 packets.  It also intentionally
does not print ENCRYPTED placeholders for ack list and DATA, to cut down
on the noise.

efad93d049 Disable TLS 1.3 support with mbed TLS
As of version 3.5.0 the TLS-Exporter function is not yet implemented in
mbed TLS, and the exporter_master_secret is not exposed to the
application either. Falling back to an older PRF when claiming to use
TLS1.3 seems like false advertising.

60def50420 Make --dns options apply for tap-windows6 driver
When tap-windows6 driver is used, both --dhcp-option and
--dns options are applied with DHCP. When processing --dns options,
we don't set "tuntap_options.dhcp_options" member, which is required
for DHCP string to be sent to the driver. As a result, --dns options
are not applied at all.

Fix by adding missing assignment of tuntap_options.dhcp_options.

2fcfb77a81 config.h: fix incorrect defines for _wopen()
This is a regression from commit

  01341840 ("add basic CMake based build")

S_IRUSR and S_IWUSR should NOT be defined as 0 but
as _S_IREAD and _S_IWRITE, as it was already fixed in commit

  077445d0 ("Fix some more wrong defines in config-msvc.h")

Those are used as permission mode when opening a file. Passing
zero makes file read-only, which break for example --status-file
functionality.

a0afe035cb Fix using to_link buffer after freed
When I refactored the tls_state_change method in
9a7b95fda5 I accidentally changed a break into
a return true while it should return a false.

The code here is extremely fragile in the sense
that it assumes that settings a keystate to S_ERROR
cannot have any outgoing buffer or we will have a
use after free.  The previous break and now restored
return false ensure this by skipping any further
tls_process_state loops that might set to ks->S_ERROR
and ensure that the to_link is sent out and cleared
before having more loops in tls_state_change.

CVE: 2023-46850

This affects everyone, even with tls-auth/tls-crypt enabled.

setting it to S_ERROR and leaving the buffer behind.

This will detect and clear that to_link buffer in that case.

a341914246 Remove saving initial frame code
This code was necessary before the frame/buffer refactoring as we
always did relative adjustment to the frame.

This also fixes also that previously initial_frame was initialised too
early before the fragment related options were initialised and contained
0 for the maximum frame size. This resulted in a DIV by 0 that caused an
abort on platforms that throw an exception for that.

CVE: 2023-46849

Only people with --fragment in their config are affected

ace7a4f1c2 Add support for mbedtls 3.X.Y
Most struct fields in mbedtls 3 are private and now need accessor
functions. Most of it was straightforward to adapt, but for two things
there were no accessor functions yet:

 * Netscape certificate type
 * key usage (you can check key usage, but not get the raw bytes)

I decided to remove Netscape certificate type checks when using OpenVPN
with mbedtls. The key usage bytes were printed in an error message, and
I removed that part from it.

Adding the random number functions to the load private key function may
look weird, but the purpose is to make side channels for elliptic curve
operations harder to exploit.

c827f9d83a dev-tools/gerrit-send-mail.py: tool to send Gerrit patchsets to Patchwork
Since we're trying to use Gerrit for patch reviews, but the actual
merge process is still implemented against the ML and Patchwork,
I wrote a script that attempts to bridge the gap.

It extracts all relevant information about a patch from Gerrit
and converts it into a mail compatible to git-am. Mostly this
work is done by Gerrit already, since we can get the original
patch in git format-patch format. But we add Acked-by information
according to the approvals in Gerrit and some other metadata.

This should allow the merge to happen based on this one mail
alone.

 - handle missing Signed-off-by line gracefully

df7beea404 dco: warn if DATA_V1 packets are sent to userspace
Servers 2.4.0 - 2.4.4 support peer-id and AEAD ciphers,
but only send DATA_V1 packets. With DCO enabled on the
client, connection is established but not working.

This is because DCO driver(s) are unable to handle
DATA_V1 packets and forwards them to userspace, where
they silently disappear since crypto context is in
DCO and not in userspace.

Starting from 2.4.5 server sends DATA_V2 so problem
doesn't happen.

We cannot switch to non-DCO on the fly, so we log this
and advice user to upgrade the server to 2.4.5 or newer.

392da5bdaa Remove ability to use configurations without TLS by default
OpenVPN 2.6 already warned about this feature being removed. OpenVPN
2.7 will with this change no longer accept these configurations without
having a --allow-deprecated-insecure-static-crypto added to the command
line or the configuration itself. This will serve as a last and final
warning for people who missed the warning message in OpenVPN 2.6.

This commit also removes the documentation for --secret and the static key
mode.

Currently we log a bogus error message saying private key password

Also log OpenSSL errors when SSL_CTX_use_certiifcate() fails in

the ceritficate is rejected by OpenSSL due to stricter security
restrictions in recent versions of the library.

b7eea48708 dns option: remove support for exclude-domains
No DNS resolver currently supports this and it is not possible to
emulate the behavior without the chance of errors. Finding the
effective default system DNS server(s) to specify the exclude
DNS routes is not trivial and cannot be verified to be correct
without resolver internal knowledge. So, it is better to not
support this instead of supporting it, but incorrectly.

0793eb105c dco: fix crash when --multihome is used with --proto tcp
Although it's a combination of options that is not really useful,
when specifying --multihome along with --proto tcp and DCO is enabled,
OpenVPN will crash while attempting to access c2.link_socket_actual
(NULL for the TCP case) in order to retrieve the local address (in
function dco_multi_get_localaddr())

Prevent crash by running this code only if proto is UDP.
The same check is already performed in socket.c/h for the non-DCO
case.

closer to where buf is first used and comment that we are not concerned
about any truncation.

If the decoded result is truncated, the NTLM server side will reject
our new response to the challenge as it will be incorrect.  The
buffer size is fixed and known to be in a cleared state before the
decode starts.

a854a7f30c signal_reset(): combine check and reset operations
- "if (sig == X) signal_reset(sig)" now becomes
  "signal_reset(sig, X)" so that the check and assignment
  can be done in one place where signals are masked.
  This is required to avoid change of signal state between
  check and reset operations.

- Avoid resetting the signal except when absolutely necessary
  (resetting has the potential of losing signals)

- In 'pre_init_signal_catch()', when certain low priority signals
  are set to SIG_IGN, clear any pending signals of the same
  type. Also, reset signal at the end of the SIGUSR1 and
  SIGHUP loops where their values are checked instead of later. This
  avoids the need for 'signal_reset()' after SIGHUP or in 'init_instance()'
  which could cause a signal like SIGTERM to be lost.
