+Subject: [PATCH] sch_cake: Make the dual modes fairer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+CAKE host fairness does not work well with TCP flows in dual-srchost and
+dual-dsthost setup. The reason is that ACKs generated by TCP flows are
+classified as sparse flows, and affect flow isolation from other hosts. Fix
+this by calculating host_load based only on the bulk flows a host
+generates. In a hash collision the host_bulk_flow_count values must be
+decremented on the old hosts and incremented on the new ones *if* the queue
+is in the bulk set.

+Subject: [PATCH] sch_cake: Permit use of connmarks as tin classifiers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add flag 'FWMARK' to enable use of firewall connmarks as tin selector.
+The connmark (skbuff->mark) needs to be in the range 1->tin_cnt ie.
+for diffserv3 the mark needs to be 1->3.
+
+Background
+
+Typically CAKE uses DSCP as the basis for tin selection.  DSCP values
+are relatively easily changed as part of the egress path, usually with
+iptables & the mangle table, ingress is more challenging.  CAKE is often
+used on the WAN interface of a residential gateway where passthrough of
+DSCP from the ISP is either missing or set to unhelpful values thus use
+of ingress DSCP values for tin selection isn't helpful in that
+environment.
+
+An approach to solving the ingress tin selection problem is to use
+CAKE's understanding of tc filters.  Naive tc filters could match on
+source/destination port numbers and force tin selection that way, but
+multiple filters don't scale particularly well as each filter must be
+traversed whether it matches or not. e.g. a simple example to map 3
+firewall marks to tins:
+
+MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
+tc filter add dev $DEV parent $MAJOR protocol all handle 0x01 fw action skbedit priority ${MAJOR}1
+tc filter add dev $DEV parent $MAJOR protocol all handle 0x02 fw action skbedit priority ${MAJOR}2
+tc filter add dev $DEV parent $MAJOR protocol all handle 0x03 fw action skbedit priority ${MAJOR}3
+
+Another option is to use eBPF cls_act with tc filters e.g.
+
+MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
+tc filter add dev $DEV parent $MAJOR bpf da obj my-bpf-fwmark-to-class.o
+
+This has the disadvantages of a) needing someone to write & maintain
+the bpf program, b) a bpf toolchain to compile it and c) needing to
+hardcode the major number in the bpf program so it matches the cake
+instance (or forcing the cake instance to a particular major number)
+since the major number cannot be passed to the bpf program via tc
+command line.
+
+As already hinted at by the previous examples, it would be helpful
+to associate tins with something that survives the Internet path and
+ideally allows tin selection on both egress and ingress.  Netfilter's
+conntrack permits setting an identifying mark on a connection which
+can also be restored to an ingress packet with tc action connmark e.g.
+
+tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \
+	match u32 0 0 flowid 1:1 action connmark action mirred egress redirect dev ifb1
+
+Since tc's connmark action has restored any connmark into skb->mark,
+any of the previous solutions are based upon it and in one form or
+another copy that mark to the skb->priority field where again CAKE
+picks this up.
+
+This change cuts out at least one of the (less intuitive &
+non-scalable) middlemen and permit direct access to skb->mark.

+Subject: [PATCH] sch_cake: Interpret fwmark parameter as a bitmask
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We initially interpreted the fwmark parameter as a flag that simply turned
+on the feature, using the whole skb->mark field as the index into the CAKE
+tin_order array. However, it is quite common for different applications to
+use different parts of the mask field for their own purposes, each using a
+different mask.
+
+Support this use of subsets of the mark by interpreting the TCA_CAKE_FWMARK
+parameter as a bitmask to apply to the fwmark field when reading it. The
+result will be right-shifted by the number of unset lower bits of the mask
+before looking up the tin.
+
+In the original commit message we also failed to credit Felix Resch with
+originally suggesting the fwmark feature back in 2017; so the Suggested-By
+in this commit covers the whole fwmark feature.
+
+Fixes: 0b5c7efdfc6e ("sch_cake: Permit use of connmarks as tin classifiers")

+Subject: [PATCH 2/2] sch_cake: drop unused variable tin_quantum_prio
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Turns out tin_quantum_prio isn't used anymore and is a leftover from a
+previous implementation of diffserv tins.  Since the variable isn't used
+in any calculations it can be eliminated.
+
+Drop variable and places where it was set.  Rename remaining variable
+and consolidate naming of intermediate variables that set it.
