[ Upstream commit b4846fc3c8559649277e3e4e6b5cec5348a8d208 ]

Andrey reported a lockdep warning on non-initialized
spinlock:

 the code is fine but needs lockdep annotation.
 turning off the locking correctness validator.

We miss a spin_lock_init() in igmpv3_add_delrec(), probably
because previously we never use it on this code path. Since
we already unlink it from the global mc_tomb list, it is
probably safe not to acquire this spinlock here. It does not
harm to have it although, to avoid conditional locking.

#1680330 — [PATCH 4.9 022/172] net: 8021q: Fix one possible panic caused by BUG_ON in free_netdev

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gao Feng <gfree.wind@vip.163.com>


[ Upstream commit 9745e362add89432d2c951272a99b0a5fe4348a9 ]

The register_vlan_device would invoke free_netdev directly, when
register_vlan_dev failed. It would trigger the BUG_ON in free_netdev
if the dev was already registered. In this case, the netdev would be
freed in netdev_run_todo later.

So add one condition check now. Only when dev is not registered, then
free it directly.

The following is the part coredump when netdev_upper_dev_link failed
in register_vlan_dev. I removed the lines which are too long.

#1680331 — [PATCH 4.9 021/172] decnet: always not take dst->__refcnt when inserting dst into hash table

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Wang <weiwan@google.com>


[ Upstream commit 76371d2e3ad1f84426a30ebcd8c3b9b98f4c724f ]

In the existing dn_route.c code, dn_route_output_slow() takes
dst->__refcnt before calling dn_insert_route() while dn_route_input_slow()
does not take dst->__refcnt before calling dn_insert_route().
This makes the whole routing code very buggy.
In dn_dst_check_expire(), dnrt_free() is called when rt expires. This
makes the routes inserted by dn_route_output_slow() not able to be
freed as the refcnt is not released.
In dn_dst_gc(), dnrt_drop() is called to release rt which could
potentially cause the dst->__refcnt to be dropped to -1.
In dn_run_flush(), dst_free() is called to release all the dst. Again,
it makes the dst inserted by dn_route_output_slow() not able to be
released and also, it does not wait on the rcu and could potentially
cause crash in the path where other users still refer to this dst.

This patch makes sure both input and output path do not take
dst->__refcnt before calling dn_insert_route() and also makes sure
dnrt_free()/dst_free() is called when removing dst from the hash table.
The only difference between those 2 calls is that dnrt_free() waits on
the rcu while dst_free() does not.

#1680335 — [PATCH 4.9 011/172] net/mlx5e: Added BW check for DIM decision mechanism

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tal Gilboa <talgi@mellanox.com>


[ Upstream commit c3164d2fc48fd4fa0477ab658b644559c3fe9073 ]

DIM (Dynamically-tuned Interrupt Moderation) is a mechanism designed for
changing the channel interrupt moderation values in order to reduce CPU
overhead for all traffic types.
Until now only interrupt and packet rate were sampled.
We found a scenario on which we get a false indication since a change in
DIM caused more aggregation and reduced packet rate while increasing BW.

We now regard a change as succesfull iff:
current_BW > (prev_BW + threshold) or
current_BW ~= prev_BW and current_PR > (prev_PR + threshold) or
current_BW ~= prev_BW and current_PR ~= prev_PR and
    current_IR < (prev_IR - threshold)
Where BW = Bandwidth, PR = Packet rate and IR = Interrupt rate

Improvements (ConnectX-4Lx 25GbE, single RX queue, LRO off)
    --------------------------------------------------
    packet size | before[Mb/s] | after[Mb/s] | gain  |
    2B          | 343.4        | 359.4       |  4.5% |

#1680337 — [PATCH 4.9 029/172] NFSv4.x/callback: Create the callback service through svc_create_pooled

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kinglong Mee <kinglongmee@gmail.com>

commit df807fffaabde625fa9adb82e3e5b88cdaa5709a upstream.

As the comments for svc_set_num_threads() said,
" Destroying threads relies on the service threads filling in
rqstp->rq_task, which only the nfs ones do.  Assumes the serv
has been created using svc_create_pooled()."

If creating service through svc_create(), the svc_pool_map_put()
will be called in svc_destroy(), but the pool map isn't used.
So that, the reference of pool map will be drop, the next using
of pool map will get a zero npools.

#1680338 — [PATCH 4.9 018/172] net/mlx5e: Avoid doing a cleanup call if the profile doesnt have it

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Or Gerlitz <ogerlitz@mellanox.com>


[ Upstream commit 31ac93386d135a6c96de9c8bab406f5ccabf5a4d ]

The error flow of mlx5e_create_netdev calls the cleanup call
of the given profile without checking if it exists, fix that.

Currently the VF reps don't register that callback and we crash
if getting into error -- can be reproduced by the user doing ctrl^C
while attempting to change the sriov mode from legacy to switchdev.

#1680340 — [PATCH 4.9 017/172] sctp: return next obj by passing pos + 1 into sctp_transport_get_idx

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Xin Long <lucien.xin@gmail.com>


[ Upstream commit 988c7322116970696211e902b468aefec95b6ec4 ]

In sctp_for_each_transport, pos is used to save how many objs it has
dumped. Now it gets the last obj by sctp_transport_get_idx, then gets
the next obj by sctp_transport_get_next.

The issue is that in the meanwhile if some objs in transport hashtable
are removed and the objs nums are less than pos, sctp_transport_get_idx
would return NULL and hti.walker.tbl is NULL as well. At this moment
it should stop hti, instead of continue getting the next obj. Or it
would cause a NULL pointer dereference in sctp_transport_get_next.

This patch is to pass pos + 1 into sctp_transport_get_idx to get the
next obj directly, even if pos > objs nums, it would return NULL and
stop hti.

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Leblond <eric@regit.org>

commit 87e94dbc210a720a34be5c1174faee5c84be963e upstream.

This patch fixes the creation of connection tracking entry from
netlink when synproxy is used. It was missing the addition of
the synproxy extension.

This was causing kernel crashes when a conntrack entry created by
conntrackd was used after the switch of traffic from active node
to the passive node.
