Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-switch, Create ingress ACL when needed
Currently, ingress acl is used for three features. It is created only
when vport metadata match and prio tag are enabled. But active-backup
lag mode also uses it. It is independent of vport metadata match and
prio tag. And vport metadata match can be disabled using the
following devlink command:
# devlink dev param set pci/0000:08:00.0 name esw_port_metadata \n value false cmode runtime
If ingress acl is not created, will hit panic when creating drop rule
for active-backup lag mode. If always create it, there will be about
5% performance degradation.
Fix it by creating ingress acl when needed. If esw_port_metadata is
true, ingress acl exists, then create drop rule using existing
ingress acl. If esw_port_metadata is false, create ingress acl and
then create drop rule.
