To configure the list of allowable TLS 1.3 ciphersuites, the option
tls_ciphersuites is used instead of tls_ciphers.

(cherry picked from commit 261df949faad6dda43454868628f79265e9cc5e7)
This addresses an issue where the list option specified in
/etc/config/openvpn i.e. 'tls_cipher' would instead show up in the
generated openvpn-<name>.conf as 'ncp-ciphers'. For context,
'ncp_ciphers' appears after 'tls_cipher' in OPENVPN_LIST from
openvpn.options.
Also, the ordering of the options in the UCI config file is now
preserved when generating the OpenVPN config. The two currently
supported list options deal with cipher preferences.

(cherry picked from commit 1d4c4cbd20580dd211431ab58460a6eebd5e021e)
For the parameters tls-cipher and ncp-ciphers more than one option can
be used in the OpenVPN configuration, separated by a colon, which should
be implemented as a list in order to configure it more clearly. By
adding the new OPENVPN_LIST option to the openvpn.options file with the
tls-cipher and ncp-cipher parameters, uci can now add this option as a
"list" and the init script will generate the appropriate OpenVPN
configuration from it.

Increase the termination timeout to 15s to let OpenVPN properly tear down

involved.

This option is used to specify a file containing PEM certs, to complete the

This change protects the openvpn instances to be marked as "in a crash
loop" and thereby the connection retries will run infinitely.
When the remote site of an openvpn connection goes down for some time
(network failure etc.) the openvpn instance in an openwrt/lede device
should not stop retrying to establish the connection.
With the current limit of 5 retries, there is a user interaction
required, which isn't really what you want when the device should
simply do everything to keep the vpn connection up.

OpenVPN 2.4 builds with mbedTLS 2.x, rename openvpn-polarssl
variant to openvpn-mbedtls.
Some feature highlights:
* Data channel cipher negotiation
* AEAD cipher support for data channel encryption (currently only
* AES-GCM)
* ECDH key exchange for control channel
* LZ4 compression support
See https://github.com/OpenVPN/openvpn/blob/master/Changes.rst

OpenVPN requires arguments to --push to be enclosed in double quotes.
One set of quotes is stripped when the UCI config is parsed.
Change append_params() of openvpn.init to enclose push parameters in
double quotes.
Unquoted push parameters do not cause errors in OpenVPN 2.3,
but OpenVPN 2.4 fails to start with unquoted push parameters.
Fixes: FS#290.

Currently, the uci data model does not provide support for specifying
the minimum TLS version supported in an OpenVPN instance (be it server
or client).
This patch adds support for writing the relevant option to the openvpn
configuration file at service startup.

Align init behaviour with other distros by starting an OpenVPN instance
for each config file found in /etc/openvpn/. This removes the additional
requirement to "register" the configs with uci and thus simplifies the
setup.
Make sure to respect the disabled state in uci to not suddenly autostart
instances which have been previously set to disabled, also skip configs
which are already started due to uci configuration.

Makes sure that the openvpn instance gets restarted in case of a crash.
Intentional stops using /etc/init.d/openvpn stop will not result in
respawning. Anything else will, e.g. killall openvpn.

[base-files] shell-scripting: fix wrong usage of '==' operator
normally the '==' is used for invoking a regex parser and is a bashism.
all of the fixes just want to compare a string. the used busybox-ash
will silently "ignore" this mistake, but make it portable/clean at least.
this patch does not change the behavior/logic of the scripts.

- clean up duplication of procd instance handling code
- using --cd *after* --config is rather pointless
- to be able to log errors properly, --syslog needs to be passed before --config
- tell procd about the generated or referenced config file instead of
the uci file. this avoids having to restart all instances if only one
of them changes.
