Vladimir Oltean 95706be13b net: mscc: ocelot: create a function that replaces an existing VCAP filter ... VCAP (Versatile Content Aware Processor) is the TCAM-based engine behind tc flower offload on ocelot, among other things. The ingress port mask on which VCAP rules match is present as a bit field in the actual key of the rule. This means that it is possible for a rule to be shared among multiple source ports. When the rule is added one by one on each desired port, that the ingress port mask of the key must be edited and rewritten to hardware. But the API in ocelot_vcap.c does not allow for this. For one thing, ocelot_vcap_filter_add() and ocelot_vcap_filter_del() are not symmetric, because ocelot_vcap_filter_add() works with a preallocated and prepopulated filter and programs it to hardware, and ocelot_vcap_filter_del() does both the job of removing the specified filter from hardware, as well as kfreeing it. That is to say, the only option of editing a filter in place, which is to delete it, modify the structure and add it back, does not work because it results in use-after-free. This patch introduces ocelot_vcap_filter_replace, which trivially reprograms a VCAP entry to hardware, at the exact same index at which it existed before, without modifying any list or allocating any memory.
