The code you are trying to compile is old. I am poking the package maintainer to get some help to upgrade it.

dsommers commented 1 year ago

@oukb Hi, I'm the Fedora Copr maintainer of ovpn-dco.

Can you test this test package? I'm in the middle of sorting out some packaging dependency challenges, but if this works I know I can push this further - at least for the Fedora 37/38 distros

and I already built my own dkms rpm from master and it was ok, but I had to rename module to ovpn-dco-v2

dsommers commented 1 year ago

Okay, that rename is a different aspect. The coming OpenVPN 2.6.3 will require a newer ovpn-dco API, which is provided in ovpn-dco-v2, while the openvpn-2.6.0 to 2.6.2 (and openvpn3-linux v20 and older) require the older API, provided by the ovpn-dco module.

Close :-) - 2.6.2 already requires ovpn-dco-v2.

2.6.3 is just a mini bugfix unrelated to DCO (so far)

Fedora 37 ships with kernel 6.5.4 now. The same issue can be seen with Fedora 38, which uses the same kernel version.

@ordex The ovpn-dco-0.2.20230426 version is getting a bit old; is it time to do a new release? Or do you have some patches I can apply on top of that tagged release?

So, there is a bug, or I doing something wrong? So far, openvpn was working fine (last month I upgraded from 2.4.12 to 2.5.9 and now 2.6.6), but I am interesting in dco module for more speed. Thank you for help or infromations. Stanislav

dsommers commented 8 months ago

@vasilko I would file that as a separate ticket. The ovpn-dco-0.2.20231010 version should be good on Fedora now, which this issue ticket tracks. The reason is that the kernel versions between RHEL/CentOS/CentOS Stream are quite different from the ones in Fedora.

OK, thank you. I will do a separate ticket. Have a nice day.
