Revision 90fd131afc565159c9e0ea742f082b337e10f8c6 authored by Florian Westphal on 23 July 2018, 10:47:14 UTC, committed by Pablo Neira Ayuso on 23 July 2018, 22:36:33 UTC
Shaochun Chen points out we leak dumper filter state allocations stored in dump_control->data in case there is an error before netlink sets cb_running (after which ->done will be called at some point). In order to fix this, add .start functions and do the allocations there. ->done is going to clean up, and in case error occurs before ->start invocation no cleanups need to be done anymore.
