[PATCH net 0/5] Netfilter fixes for net

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



The following patchset contains Netfilter fixes for net:

1) Move back the defrag users fields to the global netns_nf area.
   Kernel fails to boot if conntrack is builtin and kernel is booted
   with: nf_conntrack.enable_hooks=1. From Florian Westphal.

2) Rule event notification is missing relevant context such as
   the position handle and the NLM_F_APPEND flag.

3) Rule replacement is expanded to add + delete using the existing
   rule handle, reverse order of this operation so it makes sense
   from rule notification standpoint.

4) Remove superfluous check in the dynamic set extension which
   disallow update commands on a set without timeout.

5) Propagate to userspace the NLM_F_CREATE and NLM_F_EXCL flags
   from the rule notification path.
