Bug Description

[Impact]

xtables-addons-dkms fails to build with linux 6.2 in jammy:

/var/lib/dkms/xtables-addons/3.19/build/extensions/xt_CHAOS.c:70:46: error: implicit declaration of function ‘prandom_u32’; did you mean ‘get_random_u32’? [-Werror=implicit-function-declaration]
   70 | if (!ret || hotdrop || (unsigned int)prandom_u32() > delude_percentage)
      | ^~~~~~~~~~~
      | get_random_u32

[Test case]

 $ sudo apt install xtables-addons-dkms

With the fix applied:

 - hwe kernel 6.2:

Building for 6.2.0-25-generic
Building initial module for 6.2.0-25-generic
EFI variables are not supported on this system
/sys/firmware/efi/efivars not found, aborting.
Done.

...

[Fix]

Backport the patch(es) from Lunar to properly support the new Linux 6.2 kernel ABI.

[Regression potential]

Xtables-addons provides extra modules for iptables not present in the upstream kernel, so we may experience networking/firewall-related regressions in systems that are using this module with a 6.2 kernel.
