[PATCH net v2 0/5][pull request] Intel Wired LAN Driver Updates 2023-02-06 (ice)

[Tony Nguyen]

This series contains updates to ice driver only.

Ani removes WQ_MEM_RECLAIM flag from workqueue to resolve
check_flush_dependency warning.

Michal fixes KASAN out-of-bounds warning.

Brett corrects behaviour for port VLAN Rx filters to prevent receiving
of unintended traffic.

Dan Carpenter fixes possible off by one issue.

Zhang Changzhong adjusts error path for switch recipe to prevent memory
leak.

[PATCH net v2 1/5] ice: Do not use WQ_MEM_RECLAIM flag for workqueue

[Tony Nguyen]

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

When both ice and the irdma driver are loaded, a warning in
check_flush_dependency is being triggered. This is due to ice driver
workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the
workqueue will be involved in the kernel's memory reclamation flow.
Since it is not, there is no need for the ice driver's WQ to have this
flag set so remove it.

Example trace:

leave it empty.

[PATCH net v2 3/5] ice: Fix disabling Rx VLAN filtering with port VLAN enabled

[Tony Nguyen]

From: Brett Creeley <brett.creeley@intel.com>

If the user turns on the vf-true-promiscuous-support flag, then Rx VLAN
filtering will be disabled if the VF requests to enable promiscuous
mode. When the VF is in a port VLAN, this is the incorrect behavior
because it will allow the VF to receive traffic outside of its port VLAN
domain. Fortunately this only resulted in the VF(s) receiving broadcast
traffic outside of the VLAN domain because all of the VLAN promiscuous
rules are based on the port VLAN ID. Fix this by setting the
.disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on
the VF.

Also, make sure to make this fix for both Single VLAN Mode and Double
VLAN Mode enabled devices.

[PATCH net v2 4/5] ice: Fix off by one in ice_tc_forward_to_queue()

[Tony Nguyen]

From: Dan Carpenter <dan.carpenter@oracle.com>

The > comparison should be >= to prevent reading one element beyond
the end of the array.

The "vsi->num_rxq" is not strictly speaking the number of elements in
the vsi->rxq_map[] array.  The array has "vsi->alloc_rxq" elements and
"vsi->num_rxq" is less than or equal to the number of elements in the
array.  The array is allocated in ice_vsi_alloc_arrays().  It's still
an off by one but it might not access outside the end of the array.

[PATCH net v2 5/5] ice: switch: fix potential memleak in ice_add_adv_recipe()

[Tony Nguyen]

From: Zhang Changzhong <zhangchangzhong@huawei.com>

When ice_add_special_words() fails, the 'rm' is not released, which will
lead to a memory leak. Fix this up by going to 'err_unroll' label.

Compile tested only.
