[PATCH net 1/3] ice: Clear default forwarding VSI during VSI release

[Tony Nguyen]

From: Ivan Vecera <ivecera@redhat.com>

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.

[PATCH net 2/3] ice: Fix MAC address setting

[Tony Nguyen]

From: Ivan Vecera <ivecera@redhat.com>

Commit 2ccc1c1ccc671b ("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.

[PATCH net 3/3] ice: Fix broken IFF_ALLMULTI handling

[Tony Nguyen]

From: Ivan Vecera <ivecera@redhat.com>

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
