Maybe, but the patch is not good, I think I and Pablo gave feedback on this ?
Please trace __netlink_dump_start() content of control->module
gtp_genl_family.module should be set, and we should get it.
Otherwise, if the bug is in the core, we would need a dozen of 'work
arounds because it is better than nothing'
Thank you.
Thanks.
I tracked the moment when the __netlink_dump_start() function was
called, it turned out that in the gtp_init() initialization function
before registering pernet subsystem (gtp_net_ops), therefore, outdated
data is used, which leads to a crash.
The documentation says that ops structure must be assigned before
registering a generic netlink family [1].
I have fixed and sent a new patch [2].
