 "A fix for namespace label support for non-Intel NVDIMMs that implement
  the ACPI standard label method.

  This has apparently never worked and could wait for v5.1. However it
  has enough visibility with hardware vendors [1] and distro bug
  trackers [2], and low enough risk that I decided it should go in for
  -rc4. The other fixups target the new, for v5.0, nvdimm security
  functionality. The larger init path fixup closes a memory leak and a
  potential userspace lockup due to missed notifications.

If there are simulatenous queries of regdb, then there might be a case
where multiple queries can trigger request_firmware_no_wait and can have

might hit the WARN_ON.

During refactor in commit 9e478066 ("mac80211: fix MU-MIMO
follow-MAC mode") a new struct 'action' was declared with packed
attribute as:

  struct {
          struct ieee80211_hdr_3addr hdr;
          u8 category;
          u8 action_code;
  } __packed action;

But since struct 'ieee80211_hdr_3addr' is declared with an aligned
keyword as:

  struct ieee80211_hdr {
  	__le16 frame_control;
  	__le16 duration_id;
  	u8 addr1[ETH_ALEN];
  	u8 addr2[ETH_ALEN];
  	u8 addr3[ETH_ALEN];
  	__le16 seq_ctrl;
  	u8 addr4[ETH_ALEN];
  } __packed __aligned(2);

Solve the ambiguity of placing aligned structure in a packed one by
adding the aligned(2) attribute to struct 'action'.

This removes the following warning (W=1):

  net/mac80211/rx.c:234:2: warning: alignment 1 of 'struct <anonymous>' is less than 2 [-Wpacked-not-aligned]

syzbot reported an out-of-bounds read when passing certain
malformed messages into nl80211. The specific place where
this happened isn't interesting, the problem is that nested
policy parsing was referring to the wrong maximum attribute
and thus the policy wasn't long enough.

Fix this by referring to the correct attribute. Since this
is really not necessary, I'll come up with a separate patch
to just pass the policy instead of both, in the common case
we can infer the maxattr from the size of the policy array.

mlx4_core fixes for 5.0-rc

This patchset includes two fixes for the mlx4_core driver.

First patch by Aya fixes inaccurate parsing of some FW fields, mistakenly
including additional (mostly reserved) bits.

Second patch by Jack fixes a wrong (yet harmless) error handling of
calls to copy_to_user() during the CQs init stage.

Series generated against net commit:
49a57857 Linux 5.0-rc3
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Procedure mlx4_init_user_cqes() handles returns by copy_to_user
incorrectly. copy_to_user() returns the number of bytes not copied.
Thus, a non-zero return should be treated as a -EFAULT error
(as is done elsewhere in the kernel). However, mlx4_init_user_cqes()
error handling simply returns the number of bytes not copied
(instead of -EFAULT).

Note, though, that this is a harmless bug: procedure mlx4_alloc_cq()
(which is the only caller of mlx4_init_user_cqes()) treats any
non-zero return as an error, but that returned error value is processed
internally, and not passed further up the call stack.

In addition, fixes the following sparse warning:
warning: incorrect type in argument 1 (different address spaces)
   expected void [noderef] <asn:1>*to

Driver reads the query HCA capabilities without the corresponding masks.
Without the correct masks, the base addresses of the queues are

correct masks, ensures alignment of the base addresses and allows future
firmware versions safe use of the reserved bits.

Now sctp_transport_pmtu() passes transport->saddr into .get_dst() to set
flow sport from 'saddr'. However, transport->saddr is set only when
transport->dst exists in sctp_transport_route().

If sctp_transport_pmtu() is called without transport->saddr set, like
when transport->dst doesn't exists, the flow sport will be set to 0
from transport->saddr, which will cause a wrong route to be got.

Commit 6e91b578 ("sctp: re-use sctp_transport_pmtu in
sctp_transport_route") made the issue be triggered more easily
since sctp_transport_pmtu() would be called in sctp_transport_route()
after that.

In gerneral, fl4->fl4_sport should always be set to
htons(asoc->base.bind_addr.port), unless transport->asoc doesn't exist
in sctp_v4/6_get_dst(), which is the case:

  sctp_ootb_pkt_new() ->
    sctp_transport_route()

For that, we can simply handle it by setting flow sport from saddr only
when it's 0 in sctp_v4/6_get_dst().

    sctp_make_init_ack()
  sctp_sf_do_dupcook_a/b()() ->
    sctp_sf_do_5_1D_ce()

The new chunk 'retval' transport is set from the incoming chunk 'chunk'
transport. However, 'retval' transport belong to the new asoc, which
is a different one from 'chunk' transport's asoc.

It will cause that the 'retval' chunk gets set with a wrong transport.
Later when sending it and because of Commit b9fd6839 ("sctp: add
sctp_packet_singleton"), sctp_packet_singleton() will set some fields,
like vtag to 'retval' chunk from that wrong transport's asoc.

This patch is to fix it by setting 'retval' transport correctly which
belongs to the right asoc in sctp_make_init_ack() and
sctp_sf_do_5_1D_ce().

This patch is to improve sctp stream adding events in 2 places:

  1. In sctp_process_strreset_addstrm_out(), move up SCTP_MAX_STREAM
     and in stream allocation failure checks, as the adding has to
     succeed after reconf_timer stops for the in stream adding
     request retransmission.

  3. In sctp_process_strreset_addstrm_in(), no event should be sent,
     as no in or out stream is added here.

This patch is to improve sctp stream reset events in 4 places:

  1. In sctp_process_strreset_outreq(), the flag should always be set with
     SCTP_STREAM_RESET_INCOMING_SSN instead of OUTGOING, as receiver's in
     stream is reset here.
  2. In sctp_process_strreset_outreq(), move up SCTP_STRRESET_ERR_WRONG_SSN
     check, as the reset has to succeed after reconf_timer stops for the
     in stream reset request retransmission.
  3. In sctp_process_strreset_inreq(), no event should be sent, as no in
     or out stream is reset here.
  4. In sctp_process_strreset_resp(), SCTP_STREAM_RESET_INCOMING_SSN or
     OUTGOING event should always be sent for stream reset requests, no
     matter it fails or succeeds to process the request.

ip l add dev tun type gretap key 1000
ip a a dev tun 10.0.0.1/24

Packets with tun-id 1000 can be recived by tun dev. But packet can't
be sent through dev tun for non-tunnel-dst

With this patch: tunnel-dst can be get through lwtunnel like beflow:
