[ Test case ]
Install the latest linux-6.17 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge
Install iptables-netflow-dkms:
$ sudo apt install iptables-netflow-dkms
Module built and installed successfully.
Load the module:
$ sudo modprobe ipt_NETFLOW
Module loaded successfully.
- The same procedure can be repeated on linux-6.8 to test for possible
- regressions.
+ The same procedure must be repeated on linux-6.8 and linux-6.14 to test
+ for possible regressions.
[ Fix ]
Apply patch from iptables-netflow-dkms Questing release enabling 6.17
* debian/patches/rename-to-timer_delete_sync-in-Linux-6.15.patch
Also changing build dependency pkg-config => pkgconf
[ Regression potential ]
We may experience regressions in systems that are using the iptables-
netflow drivers, especially with kernels >= 6.8 kernel.
