With the introduction of the generic OpenVPN hotplug mechanism, wrapped
--up and --down scripts got the wrong amount and order of arguments passed,
breaking existing configurations and functionality.
Fix this issue by passing the same amount of arguments in the same expected
order as if the scripts were executed by the OpenVPN daemon directly.

If using a configuration file for OpenVPN, allow overriding name of the
interface. The reason is that then people could use configuration file
provided by VPN provider directly and override the name of the interface
to include it in correct firewall zone without need to alter the
configuration file.

Pass a default --up and --down executable to each started OpenVPN instance
which triggers /etc/hotplug.d/openvpn/ scripts whenever an instance
goes up or down.
User-configured up and down scripts are invoked by the default shipped
01-user hotplug handler to ensure that existing setups continue to work
as before.
As a consequence of this change, the up, down and script_security OpenVPN
options are removed from the option file, since we're always passing them
via the command line, they do not need to get included into the generated
configuration.

This is primarily a maintenance release with bugfixes and improvements.
This release also fixes a security issue (CVE-2020-11810) which allows
disrupting service of a freshly connected client that has not yet
negotiated session keys. The vulnerability cannot be used to
inject or steal VPN traffic.

This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into
account (if set), so that packages do not need to manually override
PKG_BUILD_DIR just to handle variants.
This also updates most base packages with variants to use the updated
default PKG_BUILD_DIR.

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.

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.

Update the OpenVPN package to version 2.4.6, refresh patches and drop
menuconfig options which are not supported upstream anymore.
Also fix the x509-alt-username configure flag - it is not supported
by mbedtls and was syntactically wrong in the Makefile - and the
port-share option which has been present in menuconfig but not been
used in the Makefile.

Update mbed TLS to 2.11.0
Disable OFB block mode and XTS block cipher mode, added in 2.11.0.
The soVersion of mbedtls changed, bump PKG_RELEASE for packages that use mbedTLS
This is to avoid having a mismatch between packages when upgrading.
The size of mbedtls increased a little bit:
ipkg for mips_24kc before:
163.846 Bytes
ipkg for mips_24kc after:
164.382 Bytes
Signed-off-by: Daniel Engberg <daniel.engberg.lists@pyret.net>
The soversion was changed in this version again and is now aligned with
the 2.7.2 version.
The size of the ipkg file stayed mostly the same.

When relying on x.509 certs for auth and / or encryption of traffic you can't
use package openvpn-nossl.
Just have your package depend on openvpn-crypto to have SSL-encryption and
X.509-support enabled in OpenVPN. If encryption / X.509 is not a must, use
virtual packge openvpn, which is provided by all OpenVPN-variants.

Add PROVIDES:=openvpn to the default recipe in order to let all build variants
provide a virtual openvpn package.
The advantage of this approach is that downstream packages can depend on just

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

[Jo-Philipp Wich: shorten commit title, bump pkg release]
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
OpenVPN assumes that its control channel messages are sent and received
unfragmented, this assumption is broken when CBC record splitting is
enabled in mbedTLS.
The record splitting is intended as countermeasure against BEAST attacks
which do not apply to OpenVPN, therefore we simply disable it until
upstream OpenVPN gains the ability to process fragmented control
messages.
Disabling the splitting also works around a (not remotely triggerable)
segmentation fault in mbedTLS.

SVN-Revision: 45602
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.
