Hi,

The following patchset contains Netfilter fixes for net:

1) Missing netns context in arp_tables, from Florian Westphal.

2) Underflow in flowtable reference counter, from wenxu.

3) Fix incorrect ethernet destination address in flowtable offload,
   from wenxu.

4) Check for status of neighbour entry, from wenxu.

5) Fix NAT port mangling, from wenxu.

6) Unbind callbacks from destroy path to cleanup hardware properly
   on flowtable removal.

7) Fix missing casting statistics timestamp, add nf_flowtable_time_stamp
   and use it.

8) NULL pointer exception when timeout argument is null in conntrack
   dccp and sctp protocol helpers, from Florian Westphal.

9) Possible nul-dereference in ipset with IPSET_ATTR_LINENO, also from
   Florian.

Hi,

This batch contains Netfilter fixes for net:

1) Restrict hashlimit size to 1048576, from Cong Wang.

2) Check for offload flags from nf_flow_table_offload_setup(),
   this fixes a crash in case the hardware offload is disabled.
   From Florian Westphal.

3) Three preparation patches to extend the conntrack clash resolution,
   from Florian.

4) Extend clash resolution to deal with DNS packets from the same flow
   racing to set up the NAT configuration.

5) Small documentation fix in pipapo, from Stefano Brivio.

6) Remove misleading unlikely() from pipapo_refill(), also from Stefano.

7) Reduce hashlimit mutex scope, from Cong Wang. This patch is actually
   triggering another problem, still under discussion, another patch to
   fix this will follow up.

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

Thank you.

Hi David,

The following patchset contains Netfilter fixes for your net tree:

1) Remove a direct dependency with IPv6 introduced by the
   sip_external_media feature, from Alin Nastac.

2) Fix bogus ENOENT when removing interval elements from set.

3) Set transport_header from br_netfilter to mimic the stack
   behaviour, this partially fixes a checksum validation bug
   from the SCTP connection tracking, from Xin Long.

   Kconfig dependencies, from Arnd Bergmann.

5) Check for NULL in skb_header_pointer() calls in ip6t_shr,
   from Kangjie Lu.

   a transaction.

7) Fix module autoload of the redirect extension.

8) Remove duplicated transition in flowtable diagram in the existing
   documentation.

Hi David,

The following patchset contains Netfilter fixes for net, specifically
fixes for the nf_conncount infrastructure which is causing troubles
since 5c789e131cbb9 ("netfilter: nf_conncount: Add list lock and gc
worker, and RCU for init tree search"). Patches aim to simplify this
infrastructure while fixing up the problems:

1) Use fixed size CONNCOUNT_SLOTS in nf_conncount, from Shawn Bohrer.

2) Incorrect signedness in age calculation from find_or_evict(),
   from Florian Westphal.

3) Proper locking for the garbage collector workqueue callback,
   first make a patch to count how many nodes can be collected
   without holding locks, then grab lock and release them. Also
   from Florian.

4) Restart node lookup from the insertion path, after releasing nodes
   via packet path garbage collection. Shawn Bohrer described a scenario
   that may result in inserting a connection in an already dead list
   node. Patch from Florian.

5) Merge lookup and add function to avoid a hold release and re-grab.
   From Florian.

6) Be safe and iterate over the node lists under the spinlock.

7) Speculative list nodes removal via garbage collection, check if
   list node got a connection while it was scheduled for deletion
   via gc.

8) Accidental argument swap in find_next_bit() that leads to more
   frequent scheduling of the workqueue. From Florian Westphal.

And one patch that falls within the miscelanea category in this batch:

9) Missing error path for nla_nest_start(), from Kangjie Lu.

Hi David,

The following patchset contains Netfilter fixes for net:

1) Make sure we don't go over the maximum jump stack boundary,
   from Taehee Yoo.

2) Missing rcu_barrier() in hash and rbtree sets, also from Taehee.

3) Missing check to nul-node in rbtree timeout routine, from Taehee.

4) Use dev->name from flowtable to fix a memleak, from Florian.

5) Oneliner to free flowtable object on removal, from Florian.

6) Memleak in chain rename transaction, again from Florian.

7) Don't allow two chains to use the same name in the same
   transaction, from Florian.

8) handle DCCP SYNC/SYNCACK as invalid, this triggers an
   uninitialized timer in conntrack reported by syzbot, from Florian.

9) Fix leak in case netlink_dump_start() fails, from Florian.

Hi David,

The following patchset contains Netfilter patches for your net tree:

1) Fix NULL pointer dereference from nf_nat_decode_session() if NAT is
   not loaded, from Prashant Bhole.

2) Fix socket extension module autoload.

3) Don't bogusly reject sets with the NFT_SET_EVAL flag set on from
   the dynset extension.

4) Fix races with nf_tables module removal and netns exit path,
   patches from Florian Westphal.

5) Don't hit BUG_ON if jumpstack goes too deep, instead hit
   WARN_ON_ONCE, from Taehee Yoo.

6) Another NULL pointer dereference from ctnetlink, again if NAT is
   not loaded, from Florian Westphal.

7) Fix x_tables match list corruption in xt_connmark module removal
   path, also from Florian.

8) nf_conncount doesn't properly deal with conntrack zones, hence
   garbage collector may get rid of entries in a different zone.
   From Yi-Hung Wei.

Hi David,

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Missing TCP header sanity check in TCPMSS target, from Eric Dumazet.

2) Incorrect event message type for related conntracks created via
   ctnetlink, from Liping Zhang.

3) Fix incorrect rcu locking when handling helpers from ctnetlink,
   from Gao feng.

4) Fix missing rcu locking when updating helper, from Liping Zhang.

5) Fix missing read_lock_bh when iterating over list of device addresses
   from TPROXY and redirect, also from Liping.

6) Fix crash when trying to dump expectations from conntrack with no
   helper via ctnetlink, from Liping.

7) Missing RCU protection to expecation list update given ctnetlink
   iterates over the list under rcu read lock side, from Liping too.

8) Don't dump autogenerated seed in nft_hash to userspace, this is
   very confusing to the user, again from Liping.

9) Fix wrong conntrack netns module refcount in ipt_CLUSTERIP,
   from Gao feng.

You can pull these changes from:

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

Thanks!

Hi David,

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Use mod_timer_pending() to avoid reactivating a dead expectation in
   the h323 conntrack helper, from Liping Zhang.

2) Oneliner to fix a type in the register name defined in the nf_tables
   header.

3) Don't try to look further when we find an inactive elements with no
   descendants in the rbtree set implementation, otherwise we crash.

4) Handle valid zero CSeq in the SIP conntrack helper, from
   Christophe Leroy.

5) Don't display a trailing slash in conntrack helper with no classes
   via /proc/net/nf_conntrack_expect, from Liping Zhang.

6) Fix an expectation leak during creation from the nfqueue path, again
   from Liping Zhang.

7) Validate netlink port ID in verdict message from nfqueue, otherwise
   an injection can be possible. Again from Zhang.

8) Reject conntrack tuples with different transport protocol on
   original and reply tuples, also from Zhang.

9) Validate offset and length in nft_exthdr, make sure they are under
   sizeof(u8), from Laura Garcia Liebana.

Hi David,

The following patchset contains Netfilter fixes for you net tree,
they are:

1) There was a race condition between parallel save/swap and delete,
   which resulted a kernel crash due to the increase ref for save, swap,
   wrong ref decrease operations. Reported and fixed by Vishwanath Pai.

2) OVS should call into CT NAT for packets of new expected connections only
   when the conntrack state is persisted with the 'commit' option to the
   OVS CT action. From Jarno Rajahalme.

3) Resolve kconfig dependencies with new OVS NAT support. From Arnd Bergmann.

4) Early validation of entry->target_offset to make sure it doesn't take us
   out from the blob, from Florian Westphal.

5) Again early validation of entry->next_offset to make sure it doesn't take
   out from the blob, also from Florian.

6) Check that entry->target_offset is always of of sizeof(struct xt_entry)
   for unconditional entries, when checking both from check_underflow()
   and when checking for loops in mark_source_chains(), again from
   Florian.

7) Fix inconsistent behaviour in nfnetlink_queue when
   NFQA_CFG_F_FAIL_OPEN is set and netlink_unicast() fails due to buffer
   overrun, we have to reinject the packet as the user expects.

8) Enforce nul-terminated table names from getsockopt GET_ENTRIES
   requests.

9) Don't assume skb->sk is set from nft_bridge_reject and synproxy,
   this fixes a recent update of the code to namespaceify
   ip_default_ttl, patch from Liping Zhang.

This batch comes with four patches to validate x_tables blobs coming
from userspace. CONFIG_USERNS exposes the x_tables interface to
unpriviledged users and to be honest this interface never received the
attention for this move away from the CAP_NET_ADMIN domain. Florian is
working on another round with more patches with more sanity checks, so
expect a bit more Netfilter fixes in this development cycle than usual.

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

Thanks!
