Hi,

The following patchset contains Netfilter fixes for net:

1) Fix gcc-10 compilation warning in nf_conntrack, from Arnd Bergmann.

2) Add NF_FLOW_HW_PENDING to avoid races between stats and deletion
   commands, from Paul Blakey.

3) Remove WQ_MEM_RECLAIM from the offload workqueue, from Roi Dayan.

4) Infinite loop when removing nf_conntrack module, from Florian Westphal.

5) Set NF_FLOW_TEARDOWN bit on expiration to avoid races when refreshing
   the timeout from the software path.

6) Missing nft_set_elem_expired() check in the rbtree, from Phil Sutter.

You can pull these changes from:

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

Thank you.

From: Arnd Bergmann <arnd@arndb.de>

gcc-10 warns around a suspicious access to an empty struct member:

net/netfilter/nf_conntrack_core.c: In function '__nf_conntrack_alloc':
net/netfilter/nf_conntrack_core.c:1522:9: warning: array subscript 0 is outside the bounds of an interior zero-length array 'u8[0]' {aka 'unsigned char[0]'} [-Wzero-length-bounds]
 1522 |  memset(&ct->__nfct_init_offset[0], 0,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from net/netfilter/nf_conntrack_core.c:37:
include/net/netfilter/nf_conntrack.h:90:5: note: while referencing '__nfct_init_offset'
   90 |  u8 __nfct_init_offset[0];
      |     ^~~~~~~~~~~~~~~~~~

The code is correct but a bit unusual. Rework it slightly in a way that
does not trigger the warning, using an empty struct instead of an empty
array. There are probably more elegant ways to do this, but this is the
smallest change.

From: Paul Blakey <paulb@mellanox.com>

Gc step can queue offloaded flow del work or stats work.
Those work items can race each other and a flow could be freed
before the stats work is executed and querying it.
To avoid that, add a pending bit that if a work exists for a flow
don't queue another work for it.
This will also avoid adding multiple stats works in case stats work
didn't complete but gc step started again.

add/del/stats we should not use WQ_MEM_RECLAIM flag.

From: Florian Westphal <fw@strlen.de>

'rmmod nf_conntrack' can hang forever, because the netns exit
gets stuck in nf_conntrack_cleanup_net_list():

i_see_dead_people:
 busy = 0;
 list_for_each_entry(net, net_exit_list, exit_list) {
  nf_ct_iterate_cleanup(kill_all, net, 0, 0);
  if (atomic_read(&net->ct.count) != 0)
   busy = 1;
 }
 if (busy) {
  schedule();
  goto i_see_dead_people;
 }

When nf_ct_iterate_cleanup iterates the conntrack table, all nf_conn
structures can be found twice:
once for the original tuple and once for the conntracks reply tuple.

get_next_corpse() only calls the iterator when the entry is
in original direction -- the idea was to avoid unneeded invocations
of the iterator callback.

When support for clashing entries was added, the assumption that
all nf_conn objects are added twice, once in original, once for reply
tuple no longer holds -- NF_CLASH_BIT entries are only added in
the non-clashing reply direction.

Thus, if at least one NF_CLASH entry is in the list then
nf_conntrack_cleanup_net_list() always skips it completely.

During normal netns destruction, this causes a hang of several
seconds, until the gc worker removes the entry (NF_CLASH entries
always have a 1 second timeout).

But in the rmmod case, the gc worker has already been stopped, so
ct.count never becomes 0.

We can fix this in two ways:

1. Add a second test for CLASH_BIT and call iterator for those
   entries as well, or:
2. Skip the original tuple direction and use the reply tuple.

2) is simpler, so do that.

If the flow timer expires, the gc sets on the NF_FLOW_TEARDOWN flag.
Otherwise, the flowtable software path might race to refresh the
timeout, leaving the state machine in inconsistent state.

Expired intervals would still match and be dumped to user space until
garbage collection wiped them out. Make sure they stop matching and
disappear (from users' perspective) as soon as they expire.

Hi David,

The following patchset contains Netfilter fixes for net:

1) Use CONFIG_NF_TABLES_INET from seltests, not NF_TABLES_INET.
   From Naresh Kamboju.

2) Add a test to cover masquerading and redirect case, from Florian
   Westphal.

3) Two packets coming from the same socket may race to set up NAT,
   ending up with different tuples and the packet losing race being
   dropped. Update nf_conntrack_tuple_taken() to exercise clash
   resolution for this case. From Martynas Pumputis and Florian
   Westphal.

4) Unbind anonymous sets from the commit and abort path, this fixes
   a splat due to double set list removal/release in case that the
   transaction needs to be aborted.

5) Do not preserve original output interface for packets that are
   redirected in the output chain when ip6_route_me_harder() is
   called. Otherwise packets end up going not going to the loopback
   device. From Eli Cooper.

6) Fix bogus splat in nft_compat with CONFIG_REFCOUNT_FULL=y, this
   also simplifies the existing logic to deal with the list insertions
   of the xtables extensions. From Florian Westphal.

Diffstat look rather larger than usual because of the new selftest, but
Florian and I consider that having tests soon into the tree is good to
improve coverage. If there's a different policy in this regard, please,
let me know.

   otherwise packets are dropped, from David Ahern.

2) Clang compilation warning uncovering typo in the
   nft_validate_register_store() call from nft_osf, from Stefan Agner.

3) Double sizeof netlink message length calculations in ctnetlink,
   from zhong jiang.

4) Missing rb_erase() on batch full in rbtree garbage collector,
   from Taehee Yoo.

5) Calm down compilation warning in nf_hook(), from Florian Westphal.

6) Missing check for non-null sk in xt_socket before validating
   netns procedence, from Flavio Leitner.

Hi David,

The following patchset contains Netfilter fixes for your net tree:

1) Missing module autoloadfor icmp and icmpv6 x_tables matches,
   from Florian Westphal.

2) Possible non-linear access to TCP header from tproxy, from
   Mate Eckl.

3) Do not allow rbtree to be used for single elements, this patch
   moves all set backend into one single module since such thing
   can only happen if hashtable module is explicitly blacklisted,
   which should not ever be done.

4) Reject error and standard targets from nft_compat for sanity
   reasons, they are never used from there.

5) Don't crash on double hashsize module parameter, from Andrey
   Ryabinin.

6) Drop dst on skb before placing it in the fragmentation
   reassembly queue, from Florian Westphal.

Hi David,

The following patchset contains Netfilter fixes for your net tree:

1) Missing netlink attribute validation in nf_queue, uncovered by KASAN,
   from Eric Dumazet.

2) Use pointer to sysctl table, save us 192 bytes of memory per netns.
   Also from Eric.

3) Possible use-after-free when removing conntrack helper modules due
   to missing synchronize RCU call. From Taehee Yoo.

4) Fix corner case in systcl writes to nf_log that lead to appending
   data to uninitialized buffer, from Jann Horn.

5) Jann Horn says we may indefinitely block other users of nf_log_mutex
   if a userspace access in proc_dostring() blocked e.g. due to a
   userfaultfd.

6) Fix garbage collection race for unconfirmed conntrack entries,
   from Florian Westphal.

You can pull these changes from:

Thanks.

Hi David,

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

1) Missing ct zone size in the nft_ct initialization path, patch
   from Florian Westphal.

2) Two patches for netfilter uapi headers, one to remove unnecessary
   sysctl.h inclusion and another to fix compilation of xt_hashlimit.h
   in userspace, from Dmitry V. Levin.

3) Patch to fix a sloppy change in nf_ct_expect that incorrectly
   simplified nf_ct_expect_related_report() in the previous nf-next
   batch. This also includes another patch for __nf_ct_expect_check()
   to report success by returning 0 to keep it consistent with other
   existing functions. From Jarno Rajahalme.

4) The ->walk() iterator of the new bitmap set type goes over the real
   bitmap size, this results in incorrect dumps when NFTA_SET_USERDATA
   is used.

Hi David,

The following patchset contains accumulated Netfilter fixes for your
net tree:

1) Ensure quota dump and reset happens iff we can deliver numbers to
   userspace.

2) Silence splat on incorrect use of smp_processor_id() from nft_queue.

3) Fix an out-of-bound access reported by KASAN in
   nf_tables_rule_destroy(), patch from Florian Westphal.

4) Fix layer 4 checksum mangling in the nf_tables payload expression
   with IPv6.

5) Fix a race in the CLUSTERIP target from control plane path when two
   threads run to add a new configuration object. Serialize invocations
   of clusterip_config_init() using spin_lock. From Xin Long.

6) Call br_nf_pre_routing_finish_bridge_finish() once we are done with
   the br_nf_pre_routing_finish() hook. From Artur Molchanov.

Hi David,

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

1) Dump only conntrack that belong to this namespace via /proc file.
   This is some fallout from the conversion to single conntrack table
   for all netns, patch from Liping Zhang.

2) Missing MODULE_ALIAS_NF_LOGGER() for the ARP family that prevents
   module autoloading, also from Liping Zhang.

3) Report overquota event to the right netnamespace, again from Liping.

4) Fix tproxy listener sk refcount that leads to crash, from
   Eric Dumazet.

5) Fix racy refcounting on object deletion from nfnetlink and rule
   removal both for nfacct and cttimeout, from Liping Zhang.

Hi David,

The following patchset contain a rather large batch for your net that
includes accumulated bugfixes, they are:

1) Run conntrack cleanup from workqueue process context to avoid hitting
   soft lockup via watchdog for large tables. This is required by the
   IPv6 masquerading extension. From Florian Westphal.

2) Use original skbuff from nfnetlink batch when calling netlink_ack()
   on error since this needs to access the skb->sk pointer.

3) Incremental fix on top of recent Sasha Levin's lock fix for conntrack
   resizing.

4) Fix several problems in nfnetlink batch message header sanitization
   and error handling, from Phil Turnbull.

5) Select NF_DUP_IPV6 based on CONFIG_IPV6, from Arnd Bergmann.

6) Fix wrong signess in return values on nf_tables counter expression,
   from Anton Protopopov.

Due to the NetDev 1.1 organization burden, I had no chance to pass up
this to you any sooner in this release cycle, sorry about that.

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) Fix accidental 3-times le/be conversion for 64-bits in nft_byteorder,
   from Florian Westphal.

2) Get rid of defensive cidr = 0 check in the ipset hash:netiface set
   type which doesn't allow valid 0.0.0.0/0 elements, also from Florian.

3) Relocate #endif in nft_ct counter support, this doesn't have any
   relation with labels.

4) Fix TCPMSS target for IPv6 when skb has CHECKSUM_COMPLETE, from
   Eric Dumazet.

5) Fix netdevice notifier leak from the error path of nf_tables_netdev.

6) Safe conntrack hashtable resizing by introducing a global lock and
   synchronize all buckets to avoid going over the maximum number of
   preemption levels, from Sasha Levin.

Hi David,

The following patchset contains Netfilter fixes for you net tree,
specifically for nf_tables and nfnetlink_queue, they are:

1) Avoid a compilation warning in nfnetlink_queue that was introduced
   in the previous merge window with the simplification of the conntrack
   integration, from Arnd Bergmann.

2) nfnetlink_queue is leaking the pernet subsystem registration from
   a failure path, patch from Nikolay Borisov.

3) Pass down netns pointer to batch callback in nfnetlink, this is the
   largest patch and it is not a bugfix but it is a dependency to
   resolve a splat in the correct way.

4) Fix a splat due to incorrect socket memory accounting with nfnetlink
   skbuff clones.

5) Add missing conntrack dependencies to NFT_DUP_IPV4 and NFT_DUP_IPV6.

6) Traverse the nftables commit list in reverse order from the commit
   path, otherwise we crash when the user applies an incremental update
   via 'nft -f' that deletes an object that was just introduced in this
   batch, from Xin Long.

Regarding the compilation warning fix, many people have sent us (and
keep sending us) patches to address this, that's why I'm including this
batch even if this is not critical.

Hi David,

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

1) Oneliner to restore maps in nf_tables since we support addressing registers
   at 32 bits level.

2) Restore previous default behaviour in bridge netfilter when CONFIG_IPV6=n,
   oneliner from Bernhard Thaler.

3) Out of bound access in ipset hash:net* set types, reported by Dave Jones'
   KASan utility, patch from Jozsef Kadlecsik.

4) Fix ipset compilation with gcc 4.4.7 related to C99 initialization of
   unnamed unions, patch from Elad Raz.

5) Add a workaround to address inconsistent endianess in the res_id field of
   nfnetlink batch messages, reported by Florian Westphal.

6) Fix error paths of CT/synproxy since the conntrack template was moved to use
   kmalloc, patch from Daniel Borkmann.

All of them look good to me to reach 4.2, I can route this to -stable myself
too, just let me know what you prefer.

Hi David,

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

1) Fix missing initialization of tuple structure in nfnetlink_cthelper
   to avoid mismatches when looking up to attach userspace helpers to
   flows, from Ian Wilson.

2) Fix potential crash in nft_hash when we hit -EAGAIN in
   nft_hash_walk(), from Herbert Xu.

3) We don't need to indicate the hook information to update the
   basechain default policy in nf_tables.

4) Restore tracing over nfnetlink_log due to recent rework to
   accomodate logging infrastructure into nf_tables.

5) Fix wrong IP6T_INV_PROTO check in xt_TPROXY.

6) Set IP6T_F_PROTO flag in nft_compat so we can use SYNPROXY6 and
   REJECT6 from xt over nftables.

Hi David,

The following batch contains netfilter fixes for your net tree, they are:

1) Fix use after free in nfnetlink when sending a batch for some
   unsupported subsystem, from Denys Fedoryshchenko.

2) Skip autoload of the nat module if no binding is specified via
   ctnetlink, from Florian Westphal.

3) Set local_df after netfilter defragmentation to avoid a bogus ICMP
   fragmentation needed in the forwarding path, also from Florian.

4) Fix potential user after free in ip6_route_me_harder() when returning
   the error code to the upper layers, from Sergey Popovich.

5) Skip possible bogus ICMP time exceeded emitted from the router (not
   valid according to RFC) if conntrack zones are used, from Vasily Averin.

6) Fix fragment handling when nf_defrag_ipv4 is loaded but nf_conntrack
   is not present, also from Vasily.

Thanks!

Hi David,

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

* Fix nf_trace in nftables if XT_TRACE=n, from Florian Westphal.

* Don't use the fast payload operation in nf_tables if the length is
  not power of 2 or it is not aligned, from Nikolay Aleksandrov.

* Fix missing break statement the inet flavour of nft_reject, which
  results in evaluating IPv4 packets with the IPv6 evaluation routine,
  from Patrick McHardy.

* Fix wrong kconfig symbol in nft_meta to match the routing realm,
  from Paul Bolle.

* Allocate the NAT null binding when creating new conntracks via
  ctnetlink to avoid that several packets race at initializing the
  the conntrack NAT extension, original patch from Florian Westphal,
  revisited version from me.

* Fix DNAT handling in the snmp NAT helper, the same handling was being
  done for SNAT and DNAT and 2.4 already contains that fix, from
  Francois-Xavier Le Bail.
