Core Update 175: Ship vpnmain.cgi

Signed-off-by: Peter Müller peter.mueller@ipfire.org

commit 94aa82fa619448229737bf545b768f0ca7177b0c Author: Adolf Belka adolf.belka@ipfire.org Date: Sat Jun 3 16:05:41 2023 +0200

vpnmain.cgi: Fixes bug#13138 - root/host certificate set fails to be created

- The change to openssl-3.x results in the openssl commands that start with ca failing with the error message OpenSSL produced an error: <br>40E7B4719B730000:error:0700006C:configuration file routines:NCONF_get_string:no value:crypto/conf/conf_lib.c:315:group=<NULL> name=unique_subject - The fix for this is to include the unique_subject = yes line into /var/ipfire/certs/index.txt.attr - Additionally, based on the learnings from bug#13137 on OpenVPN, any openssl commands dealing with pkcs12 (.p12) files that were created with openssl-1.1.1x fail when being accessed with openssl-3.x due to the no longer supported algorithm. These can be accessed if the -legacy option is added to every openssl command dealing with pkcs12

backup.pl: Fixes Bug#13137 - Existing n2n client connection created with openssl-1.1.1x fails to start with openssl-3.x

- This code adds the "providers legacy default" line into OpenVPN N2N Client config files when restoring them in case it is missing from a backup earlier than CU175. Only adds the line if it is not already present. - Tested out on my vm testbed system

update.sh: Fixes Bug#13137 - Existing n2n client connection created with openssl-1.1.1x fails to start with openssl-3.x

- This modification will check if ovpnconfig exists and is not empty. If so then it will check for all n2n connections and if they are Client configs will check if "providers legacy default" is not already present and if so will add it.

ovpnmain.cgi: Fixes Bug#13137 - Existing n2n client connection created with openssl-1.1.1x fails to start with openssl-3.x

- With a n2n connection .p12 certificate created wityh openssl-1.1.1x the line providers legacy default is required in the n2nconf file to enable it to start. - Any openssl-3.x attempt to open a .p12 file created with openssl-1.1.1x will result in a failure and an error message. All the openssl commands dealing with pkcs12 (.p12) files need to have the -legacy option added to them.
