Workaround for conflicting with module `nf_conntrack_netlink`
|
|
---
|
|
This module uses conntrack events to register a callback function. In the same netns, only one callback method can be registered, that causes conflicts with `nf_conntrack_netlink`, which also uses conntrack events. Qualcomm Shortcut FE has introduced a patch to allow multiple callbacks to be registered. To apply, put [this patch](https://github.com/coolsnowwolf/lede/blob/master/target/linux/generic/hack-4.14/952-net-conntrack-events-support-multiple-registrant.patch) into `target/linux/generic/hack-4.14`.
