When we receive an SSL alert from a server we currently only log a
very cryptic OpenSSL error message:
OpenSSL: error:0A00042E:SSL routines::tlsv1 alert protocol version:SSL alert number 70
This also enables logging the much more readable SSL error message:
Received fatal SSL alert: protocol version
which previously needed --verb 8 to be displayed (now verb 3). Also rework the
message to be better readable.

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.

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.

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.

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.

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 is a find cases where the session already has planned to send out
a packet but encounters some other errors that invalidate the session,
setting it to S_ERROR and leaving the buffer behind.
This will detect and clear that to_link buffer in that case.

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

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.

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.
v3:
- handle missing display_name and email fields for reviewers
gracefully
- handle missing Signed-off-by line gracefully
v4:
- use formatted string consistently

The -fno-sanitize-recover=all flag ensures that for all errors we actually
abort the tests in the automated testing and not just print some errors in red
that nobody sees. Also add the undefined tests to catch more bugs.
For libreSSL we do not add the udefined behaviour as we have (even with the
latest LibreSSL version) an undefined behaviour in LibreSSL itself.

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.

OpenSSL has a weird way of only reporting EC curves that are implemented
in a certain way in the list of all EC curves. Note this fact and point
out that also the very important curves X448 and X25519 are affected.

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
verification failed when SSL_CTX_use_cert_and_key() fails in
pkcs11_openssl.c. Instead print OpenSSL error queue and exit promptly.
Also log OpenSSL errors when SSL_CTX_use_certiifcate() fails in
cryptoapi.c and elsewhere. Such logging could be useful especially when
the ceritficate is rejected by OpenSSL due to stricter security
restrictions in recent versions of the library.

Not on every push due to submit limits.
Use caching to not submit a scan for the same git commit
twice. Since we have many days without pushes to master
this saves a lot of Github and Coverity resources.
v2:
- add caching to not submit redundant scans

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.

These are based on review comments for the 2.6 backport.
But since they apply to the original master implementation
as well, I address them in this separate patch.
- Add documentation to contrib/cmake/*.py
- Fix grammar in README.cmake.md
- Update a TODO in CMakeLists.txt to better reflect
the status quo
- Fix indentation in unit_tests' Makefile.am

While CMake is not the official way to build OpenVPN on Linux,
it still make sense to support it. Turns out that
HAVE_SETSID, HAVE_OPENLOG and HAVE_SYSLOG
were not set by CMake configure, and --daemon and syslog
functionality was broken.
While on it, fix compiler error on unused return value of chdir().

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.

Currently, OCC exit messages are only logged at some high debug level
(and if OpenVPN compiled with DEBUG), while control-channel EEN messages
are logged on verb 1. Make this consistent, both in wording and in
log level.
Both messages are prefixed with the "channel" where the exit message
came in.

The code was not very clear if we accept the base64 decode if the
NTLM challenge was truncated or not. Move the related code lines
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.
