Subject: [PATCH] sch_cake: don't try to reallocate or unshare skb
unconditionally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
cake_handle_diffserv() tries to linearize mac and network header parts of
skb and to make it writable unconditionally. In some cases it leads to full
skb reallocation, which reduces throughput and increases CPU load. Some
measurements of IPv4 forward + NAPT on MIPS router with 580 MHz single-core
CPU was conducted. It appears that on kernel 4.9 skb_try_make_writable()
reallocates skb, if skb was allocated in ethernet driver via so-called
'build skb' method from page cache (it was discovered by strange increase
of kmalloc-2048 slab at first).
Obtain DSCP value via read-only skb_header_pointer() call, and leave
linearization only for DSCP bleaching or ECN CE setting. And, as an
additional optimisation, skip diffserv parsing entirely if it is not needed
by the current configuration.

MIME-Version: 1.0

Change tin mapping on diffserv3, 4 & 8 for LE PHB support, in essence
making LE a member of the Bulk tin.
Bulk has the least priority and minimum of 1/16th total bandwidth in the
face of higher priority traffic.
NB: Diffserv 3 & 4 swap tin 0 & 1 priorities from the default order as
found in diffserv8, in case anyone is wondering why it looks a bit odd.

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.

Subject: [PATCH] sch_cake: Take advantage of skb->hash where appropriate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
While the other fq-based qdiscs take advantage of skb->hash and doesn't
recompute it if it is already set, sch_cake does not.
This was a deliberate choice because sch_cake hashes various parts of the
packet header to support its advanced flow isolation modes. However,
foregoing the use of skb->hash entirely loses a few important benefits:
- When skb->hash is set by hardware, a few CPU cycles can be saved by not
hashing again in software.
- Tunnel encapsulations will generally preserve the value of skb->hash from
before the encapsulation, which allows flow-based qdiscs to distinguish
between flows even though the outer packet header no longer has flow
information.
It turns out that we can preserve these desirable properties in many cases,
while still supporting the advanced flow isolation properties of sch_cake.
This patch does so by reusing the skb->hash value as the flow_hash part of
the hashing procedure in cake_hash() only in the following conditions:
- If the skb->hash is marked as covering the flow headers (skb->l4_hash is
set)
AND
- NAT header rewriting is either disabled, or did not change any values
used for hashing. The latter is important to match local-origin packets
such as those of a tunnel endpoint.
The immediate motivation for fixing this was the recent patch to WireGuard
to preserve the skb->hash on encapsulation. As such, this is also what I
tested against; with this patch, added latency under load for competing
flows drops from ~8 ms to sub-1ms on an RRUL test over a WireGuard tunnel
going through a virtual link shaped to 1Gbps using sch_cake. This matches
the results we saw with a similar setup using sch_fq_codel when testing the
WireGuard patch.

Subject: [PATCH] sch_cake: don't try to reallocate or unshare skb
unconditionally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
cake_handle_diffserv() tries to linearize mac and network header parts of
skb and to make it writable unconditionally. In some cases it leads to full
skb reallocation, which reduces throughput and increases CPU load. Some
measurements of IPv4 forward + NAPT on MIPS router with 580 MHz single-core
CPU was conducted. It appears that on kernel 4.9 skb_try_make_writable()
reallocates skb, if skb was allocated in ethernet driver via so-called
'build skb' method from page cache (it was discovered by strange increase
of kmalloc-2048 slab at first).
Obtain DSCP value via read-only skb_header_pointer() call, and leave
linearization only for DSCP bleaching or ECN CE setting. And, as an
additional optimisation, skip diffserv parsing entirely if it is not needed
by the current configuration.

Change tin mapping on diffserv3, 4 & 8 for LE PHB support, in essence
making LE a member of the Bulk tin.
Bulk has the least priority and minimum of 1/16th total bandwidth in the
face of higher priority traffic.
NB: Diffserv 3 & 4 swap tin 0 & 1 priorities from the default order as
found in diffserv8, in case anyone is wondering why it looks a bit odd.

Subject: [PATCH] sch_cake: fix IP protocol handling in the presence of VLAN
tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Ilya Ponetayev <i.ponetaev@ndmsystems.com>
CAKE was using the return value of tc_skb_protocol() and expecting it to be
the IP protocol type. This can fail in the presence of QinQ VLAN tags,
making CAKE unable to handle ECN marking and diffserv parsing in this case.
Fix this by implementing our own version of tc_skb_protocol(), which will
use skb->protocol directly, but also parse and skip over any VLAN tags and
return the inner protocol number instead.
Also fix CE marking by implementing a version of INET_ECN_set_ce() that
uses the same parsing routine.
