[PATCH 00/13] netfilter fixes for net

Hi David,

The following patchset contains netfilter updates for your net tree,
they are:

1) Fix refcount leak when dumping the dying/unconfirmed conntrack lists,
   from Florian Westphal.

2) Fix crash in NAT when removing a netnamespace, also from Florian.

3) Fix a crash in IPVS when trying to remove an estimator out of the
   sysctl scope, from Julian Anastasov.

4) Add zone attribute to the routing to calculate the message size in
   ctnetlink events, from Ken-ichirou MATSUZAWA.

5) Another fix for the dying/unconfirmed list which was preventing to
   dump more than one memory page of entries (~17 entries in x86_64).

6) Fix missing RCU-safe list insertion in the rule replacement code
   in nf_tables.

7) Since the new transaction infrastructure is in place, we have to
   upgrade the chain use counter from u16 to u32 to avoid overflow
   after more than 2^16 rules are added.

8) Fix refcount leak when replacing rule in nf_tables. This problem
   was also introduced in new transaction.

9) Call the ->destroy() callback when releasing nft-xt rules to fix
   module refcount leaks.

10) Set the family in the netlink messages that contain set elements
    in nf_tables to make it consistent with other object types.

11) Don't dump NAT port information if it is unset in nft_nat.

12) Update the MAINTAINERS file, I have merged the ebtables entry
    into netfilter. While at it, also removed the netfilter users
    mailing list, the development list should be enough.

You can pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf.git

Thanks!

Since 4fefee5 ("netfilter: nf_tables: allow to delete several objects
from a batch"), every new rule bumps the chain use counter. However,
this is limited to 16 bits, which means that it will overrun after
2^16 rules.

Use a u32 chain counter and check for overflows (just like we do for
table objects).

The tot_stats estimator is started only when CONFIG_SYSCTL
is defined. But it is stopped without checking CONFIG_SYSCTL.
Fix the crash by moving ip_vs_stop_estimator into
ip_vs_control_net_cleanup_sysctl.

The change is needed after commit 14e405461e664b
("IPVS: Add __ip_vs_control_{init,cleanup}_sysctl()") from 2.6.39.

The dumping prematurely stops, it seems the callback argument that
indicates that all entries have been dumped is set after iterating
on the first cpu list. The dumping also may stop before the entire
per-cpu list content is also dumped.

With this patch, conntrack -L dying now shows the dying list content
again.

From: Florian Westphal <fw@strlen.de>

'last' keeps track of the ct that had its refcnt bumped during previous
dump cycle.  Thus it must not be overwritten until end-of-function.

Another (unrelated, theoretical) issue: Don't attempt to bump refcnt of a conntrack
whose reference count is already 0.  Such conntrack is being destroyed
right now, its memory is freed once we release the percpu dying spinlock.

that is replaced needs to be handled as a deleted rule.

From: Florian Westphal <fw@strlen.de>

Quoting Samu Kallio:

 Basically what's happening is, during netns cleanup,
 nf_nat_net_exit gets called before ipv4_net_exit. As I understand
 it, nf_nat_net_exit is supposed to kill any conntrack entries which
 have NAT context (through nf_ct_iterate_cleanup), but for some
 reason this doesn't happen (perhaps something else is still holding
 refs to those entries?).

 When ipv4_net_exit is called, conntrack entries (including those
 with NAT context) are cleaned up, but the
 nat_bysource hashtable is long gone - freed in nf_nat_net_exit. The
 bug happens when attempting to free a conntrack entry whose NAT hash
 'prev' field points to a slot in the freed hash table (head for that
 bin).

We ignore conntracks with null nat bindings.  But this is wrong,
as these are in bysource hash table as well.

Restore nat-cleaning for the netns-is-being-removed case.
