Previous versions of the patch had issues with string concatenation
(missing whitespace) - all fixed. Also, the manpage would claim
auto-activation of the feature, which it didn't -> fixed as well :-)
Testing with manual activation of --force-tls-key-material-export led
to the expected result - 2.6 clients could connect fine, 2.5 and earlier
were refused with a clear message:
2024-01-03 18:35:45 AUTH: Received control message: AUTH_FAILED,Client
incompatible with this server. Keying Material Exporters (RFC 5705) support
missing. Upgrade to a client that supports this feature (OpenVPN 2.6.0+).
and on the server
2024-01-03 18:37:52 us=455522
cron2-freebsd-tc-amd64-25/2001:608:0:814::f000:21 peer-id=0 PUSH: client does
not support TLS key material exportbut --force-tls-key-material-export is
enabled.
so, this should help people hitting such a scenario to much better understand
what is happening, and what they can do about it.
For completeness I've tried to test this on a FreeBSD 14 system with
"--providers fips", but failed to set up OpenSSL/FIPS in a way that
actually did anything useful... so I broke check_tls_prf_working()
manually, and the expected "auto-enable option" part works too. <<< NAK!
Your patch has been applied to the master and release/2.6 branch (long-
