Hi,

The following patchset contains Netfilter fixes for net:

1) If user requests to wake up a table and hook fails, restore the
   dormant flag from the error path, from Florian Westphal.

2) Reset dst after transferring it to the flow object, otherwise dst
   gets released twice from the error path.

3) Release dst in case the flowtable selects a direct xmit path, eg.
   transmission to bridge port. Otherwise, dst is memleaked.

4) Register basechain and flowtable hooks at the end of the command.
   Error path releases these datastructure without waiting for the
   rcu grace period.

5) Use kzalloc() to initialize struct nft_hook to fix a KMSAN report
   on access to hook type, also from Florian Westphal.

Please, pull these changes from:

Thanks.
