SRU Justification:
net: Fix return value of qdisc ingress handling on success
* Explain the bug(s)
Currently qdisc ingress handling (sch_handle_ingress()) doesn't
set a return value and it is left to the old return value of
the caller (__netif_receive_skb_core()) which is RX drop, so if
the packet is consumed, caller will stop and return this value
as if the packet was dropped.
* brief explanation of fixes
Fix that by setting the return value to RX success if
the packet was handled successfully.
* How to test
Commit msg has the steps.
* What it could break.
Packet on egress tc rule forwarding to a ingress tc rule will drop.
SRU Justification:
netfilter: conntrack: annotate data-races around ct->timeout
netfilter: conntrack: remove unneeded nf_ct_put
netfilter: conntrack: convert to refcount_t api
netfilter: flowtable: Make sure GC works periodically in idle system
netfilter: flowtable: avoid possible false sharing
netfilter: flowtable: fix excessive hw offload attempts after failure
netfilter: nf_flowtable: expose nf_flow_table_gc_cleanup()
netfilter: flowtable: add function to invoke garbage collection immediately
netfilter: flowtable: fix stuck flows on cleanup due to pending work
* Explain the bug(s)
Set of patches to increase stability with connection tracking offload,
including reduced cpu load and possible deadlock on cleanup.
* brief explanation of fixes
Fix that by setting the return value to RX success if
the packet was handled successfully.
* How to test
Run connection tracking hw offload scenario with millions of flows, check cpu load, test cleanup and readd scenarios.
* What it could break.
High cpu load. Possible deadlock on cleanup. |
