      KS8851_MLL selects MICREL_PHY, which depends on PTP_1588_CLOCK_OPTIONAL,
so make KS8851_MLL also depend on PTP_1588_CLOCK_OPTIONAL since
'select' does not follow any dependency chains.

Fixes kconfig warning and build errors:

      Matt Johnston authored 
      Previously the skb was allocated with headroom MCTP_HEADER_MAXLEN,
but that isn't sufficient if we are using devs that are not MCTP

This also adds a check that the smctp_halen provided to sendmsg for

      ice: Fix broken IFF_ALLMULTI handling · 1273f895
      Ivan Vecera authored 
      Handling of all-multicast flag and associated multicast promiscuous
mode is broken in ice driver. When an user switches allmulticast
flag on or off the driver checks whether any VLANs are configured
over the interface (except default VLAN 0).

If any extra VLANs are registered it enables multicast promiscuous
mode for all these VLANs (including default VLAN 0) using
ICE_SW_LKUP_PROMISC_VLAN look-up type. In this situation all
multicast packets tagged with known VLAN ID or untagged are received
and multicast packets tagged with unknown VLAN ID ignored.

If no extra VLANs are registered (so only VLAN 0 exists) it enables
multicast promiscuous mode for VLAN 0 and uses ICE_SW_LKUP_PROMISC
look-up type. In this situation any multicast packets including
tagged ones are received.

The driver handles IFF_ALLMULTI in ice_vsi_sync_fltr() this way:

ice_vsi_sync_fltr() {
  ...
  if (changed_flags & IFF_ALLMULTI) {
    if (netdev->flags & IFF_ALLMULTI) {
      if (vsi->num_vlans > 1)
        ice_set_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS);
      else
        ice_set_promisc(..., ICE_MCAST_PROMISC_BITS);
    } else {
      if (vsi->num_vlans > 1)
        ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS);
      else
        ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS);
    }
  }
  ...
}

The code above depends on value vsi->num_vlan that specifies number
of VLANs configured over the interface (including VLAN 0) and
this is problem because that value is modified in NDO callbacks
ice_vlan_rx_add_vid() and ice_vlan_rx_kill_vid().

Scenario 1:
1. ip link set ens7f0 allmulticast on
2. ip link add vlan10 link ens7f0 type vlan id 10
3. ip link set ens7f0 allmulticast off
4. ip link set ens7f0 allmulticast on

[1] In this scenario IFF_ALLMULTI is enabled and the driver calls
    ice_set_promisc(..., ICE_MCAST_PROMISC_BITS) that installs
    multicast promisc rule with non-VLAN look-up type.
[2] Then VLAN with ID 10 is added and vsi->num_vlan incremented to 2
[3] Command switches IFF_ALLMULTI off and the driver calls
    ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS) but this
    call is effectively NOP because it looks for multicast promisc
    rules for VLAN 0 and VLAN 10 with VLAN look-up type but no such
    rules exist. So the all-multicast remains enabled silently
    in hardware.
[4] Command tries to switch IFF_ALLMULTI on and the driver calls
    ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS) but this call
    fails (-EEXIST) because non-VLAN multicast promisc rule already
    exists.

Scenario 2:
1. ip link add vlan10 link ens7f0 type vlan id 10
2. ip link set ens7f0 allmulticast on
3. ip link add vlan20 link ens7f0 type vlan id 20
4. ip link del vlan10 ; ip link del vlan20
5. ip link set ens7f0 allmulticast off

[1] VLAN with ID 10 is added and vsi->num_vlan==2
[2] Command switches IFF_ALLMULTI on and driver installs multicast
    promisc rules with VLAN look-up type for VLAN 0 and 10
[3] VLAN with ID 20 is added and vsi->num_vlan==3 but no multicast
    promisc rules is added for this new VLAN so the interface does
    not receive MC packets from VLAN 20
[4] Both VLANs are removed but multicast rule for VLAN 10 remains
    installed so interface receives multicast packets from VLAN 10
[5] Command switches IFF_ALLMULTI off and because vsi->num_vlan is 1
    the driver tries to remove multicast promisc rule for VLAN 0
    with non-VLAN look-up that does not exist.
    All-multicast looks disabled from user point of view but it
    is partially enabled in HW (interface receives all multicast
    packets either untagged or tagged with VLAN ID 10)

To resolve these issues the patch introduces these changes:
1. Adds handling for IFF_ALLMULTI to ice_vlan_rx_add_vid() and
   ice_vlan_rx_kill_vid() callbacks. So when VLAN is added/removed
   and IFF_ALLMULTI is enabled an appropriate multicast promisc
   rule for that VLAN ID is added/removed.
2. In ice_vlan_rx_add_vid() when first VLAN besides VLAN 0 is added
   so (vsi->num_vlan == 2) and IFF_ALLMULTI is enabled then look-up
   type for existing multicast promisc rule for VLAN 0 is updated
   to ICE_MCAST_VLAN_PROMISC_BITS.
3. In ice_vlan_rx_kill_vid() when last VLAN besides VLAN 0 is removed
   so (vsi->num_vlan == 1) and IFF_ALLMULTI is enabled then look-up
   type for existing multicast promisc rule for VLAN 0 is updated
   to ICE_MCAST_PROMISC_BITS.
4. Both ice_vlan_rx_{add,kill}_vid() have to run under ICE_CFG_BUSY
   bit protection to avoid races with ice_vsi_sync_fltr() that runs
   in ice_service_task() context.
5. Bit ICE_VSI_VLAN_FLTR_CHANGED is use-less and can be removed.
6. Error messages added to ice_fltr_*_vsi_promisc() helper functions
   to avoid them in their callers
7. Small improvements to increase readability

      ice: Fix MAC address setting · 2c0069f3
      Ivan Vecera authored 
      Commit 2ccc1c1c ("ice: Remove excess error variables") merged
the usage of 'status' and 'err' variables into single one in
function ice_set_mac_address(). Unfortunately this causes
a regression when call of ice_fltr_add_mac() returns -EEXIST because
this return value does not indicate an error in this case but
value of 'err' remains to be -EEXIST till the end of the function
and is returned to caller.

Prior mentioned commit this does not happen because return value of
ice_fltr_add_mac() was stored to 'status' variable first and
if it was -EEXIST then 'err' remains to be zero.

Fix the problem by reset 'err' to zero when ice_fltr_add_mac()
returns -EEXIST.

      ice: Clear default forwarding VSI during VSI release · bd8c624c
      Ivan Vecera authored 
      VSI is set as default forwarding one when promisc mode is set for
PF interface, when PF is switched to switchdev mode or when VF
driver asks to enable allmulticast or promisc mode for the VF
interface (when vf-true-promisc-support priv flag is off).
The third case is buggy because in that case VSI associated with
VF remains as default one after VF removal.

Reproducer:
1. Create VF
   echo 1 > sys/class/net/ens7f0/device/sriov_numvfs
2. Enable allmulticast or promisc mode on VF
   ip link set ens7f0v0 allmulticast on
   ip link set ens7f0v0 promisc on
3. Delete VF
   echo 0 > sys/class/net/ens7f0/device/sriov_numvfs
4. Try to enable promisc mode on PF
   ip link set ens7f0 promisc on

Although it looks that promisc mode on PF is enabled the opposite
is true because ice_vsi_sync_fltr() responsible for IFF_PROMISC
handling first checks if any other VSI is set as default forwarding
one and if so the function does not do anything. At this point
it is not possible to enable promisc mode on PF without re-probe
device.

To resolve the issue this patch clear default forwarding VSI
during ice_vsi_release() when the VSI to be released is the default
one.

      Revert "net: dsa: stop updating master MTU from master.c" · 066dfc42
      Vladimir Oltean authored 
      This reverts commit a1ff94c2.

Switch drivers that don't implement ->port_change_mtu() will cause the
DSA master to remain with an MTU of 1500, since we've deleted the other
code path. In turn, this causes a regression for those systems, where
MTU-sized traffic can no longer be terminated.

Revert the change taking into account the fact that rtnl_lock() is now
taken top-level from the callers of dsa_master_setup() and
dsa_master_teardown(). Also add a comment in order for it to be
absolutely clear why it is still needed.

      skbuff: fix coalescing for page_pool fragment recycling · 1effe8ca
      Jean-Philippe Brucker authored 
      Fix a use-after-free when using page_pool with page fragments. We
encountered this problem during normal RX in the hns3 driver:

(1) Initially we have three descriptors in the RX queue. The first one
    allocates PAGE1 through page_pool, and the other two allocate one
    half of PAGE2 each. Page references look like this:

                RX_BD1 _______ PAGE1
                RX_BD2 _______ PAGE2
                RX_BD3 _________/

(2) Handle RX on the first descriptor. Allocate SKB1, eventually added
    to the receive queue by tcp_queue_rcv().

(3) Handle RX on the second descriptor. Allocate SKB2 and pass it to
    netif_receive_skb():

    netif_receive_skb(SKB2)
      ip_rcv(SKB2)
        SKB3 = skb_clone(SKB2)

    SKB2 and SKB3 share a reference to PAGE2 through
    skb_shinfo()->dataref. The other ref to PAGE2 is still held by
    RX_BD3:

                      SKB2 ---+- PAGE2
                      SKB3 __/   /
                RX_BD3 _________/

 (3b) Now while handling TCP, coalesce SKB3 with SKB1:

      tcp_v4_rcv(SKB3)
        tcp_try_coalesce(to=SKB1, from=SKB3)    // succeeds
        kfree_skb_partial(SKB3)
          skb_release_data(SKB3)                // drops one dataref

                      SKB1 _____ PAGE1
                           \____
                      SKB2 _____ PAGE2
                                 /
                RX_BD3 _________/

    In skb_try_coalesce(), __skb_frag_ref() takes a page reference to
    PAGE2, where it should instead have increased the page_pool frag
    reference, pp_frag_count. Without coalescing, when releasing both
    SKB2 and SKB3, a single reference to PAGE2 would be dropped. Now
    when releasing SKB1 and SKB2, two references to PAGE2 will be
    dropped, resulting in underflow.

 (3c) Drop SKB2:

      af_packet_rcv(SKB2)
        consume_skb(SKB2)
          skb_release_data(SKB2)                // drops second dataref
            page_pool_return_skb_page(PAGE2)    // drops one pp_frag_count

                      SKB1 _____ PAGE1
                           \____
                                 PAGE2
                                 /
                RX_BD3 _________/

(4) Userspace calls recvmsg()
    Copies SKB1 and releases it. Since SKB3 was coalesced with SKB1, we
    release the SKB3 page as well:

    tcp_eat_recv_skb(SKB1)
      skb_release_data(SKB1)
        page_pool_return_skb_page(PAGE1)
        page_pool_return_skb_page(PAGE2)        // drops second pp_frag_count

(5) PAGE2 is freed, but the third RX descriptor was still using it!
    In our case this causes IOMMU faults, but it would silently corrupt
    memory if the IOMMU was disabled.

Change the logic that checks whether pp_recycle SKBs can be coalesced.
We still reject differing pp_recycle between 'from' and 'to' SKBs, but
in order to avoid the situation described above, we also reject
coalescing when both 'from' and 'to' are pp_recycled and 'from' is
cloned.

The new logic allows coalescing a cloned pp_recycle SKB into a page
refcounted one, because in this case the release (4) will drop the right
reference, the one taken by skb_try_coalesce().

      vrf: fix packet sniffing for traffic originating from ip tunnels · 012d69fb
      Eyal Birger authored 
      in commit 04893908
("vrf: add mac header for tunneled packets when sniffer is attached")
an Ethernet header was cooked for traffic originating from tunnel devices.

However, the header is added based on whether the mac_header is unset
and ignores cases where the device doesn't expose a mac header to upper
layers, such as in ip tunnels like ipip and gre.

Traffic originating from such devices still appears garbled when capturing
on the vrf device.

Fix by observing whether the original device exposes a header to upper
layers, similar to the logic done in af_packet.

In addition, skb->mac_len needs to be adjusted after adding the Ethernet
header for the skb_push/pull() surrounding dev_queue_xmit_nit() to work
on these packets.

      net: sfc: add missing xdp queue reinitialization · 059a47f1
      Taehee Yoo authored 
      After rx/tx ring buffer size is changed, kernel panic occurs when
it acts XDP_TX or XDP_REDIRECT.

When tx/rx ring buffer size is changed(ethtool -G), sfc driver
reallocates and reinitializes rx and tx queues and their buffer
(tx_queue->buffer).
But it misses reinitializing xdp queues(efx->xdp_tx_queues).
So, while it is acting XDP_TX or XDP_REDIRECT, it uses the uninitialized
tx_queue->buffer.

A new function efx_set_xdp_channels() is separated from efx_set_channels()
to handle only xdp queues.

Splat looks like:
