net, sched: add clsact qdisc
This work adds a generalization of the ingress qdisc as a qdisc holding
only classifiers. The clsact qdisc works on ingress, but also on egress.
In both cases, it's execution happens without taking the qdisc lock, and
the main difference for the egress part compared to prior version of [1]
is that this can be applied with _any_ underlying real egress qdisc (also
classless ones).
Besides solving the use-case of [1], that is, allowing for more programmability
on assigning skb->priority for the mqprio case that is supported by most
popular 10G+ NICs, it also opens up a lot more flexibility for other tc
applications. The main work on classification can already be done at clsact
egress time if the use-case allows and state stored for later retrieval
f.e. again in skb->priority with major/minors (which is checked by most
classful qdiscs before consulting tc_classify()) and/or in other skb fields
like skb->tc_index for some light-weight post-processing to get to the
eventual classid in case of a classful qdisc. Another use case is that
the clsact egress part allows to have a central egress counterpart to
the ingress classifiers, so that classifiers can easily share state (e.g.
in cls_bpf via eBPF maps) for ingress and egress.
Currently, default setups like mq + pfifo_fast would require for this to
use, for example, prio qdisc instead (to get a tc_classify() run) and to
duplicate the egress classifier for each queue. With clsact, it allows
for leaving the setup as is, it can additionally assign skb->priority to
put the skb in one of pfifo_fast's bands and it can share state with maps.
Moreover, we can access the skb's dst entry (f.e. to retrieve tclassid)
w/o the need to perform a skb_dst_force() to hold on to it any longer. In
lwt case, we can also use this facility to setup dst metadata via cls_bpf
(bpf_skb_set_tunnel_key()) without needing a real egress qdisc just for
that (case of IFF_NO_QUEUE devices, for example).
The realization can be done without any changes to the scheduler core
framework. All it takes is that we have two a-priori defined minors/child
classes, where we can mux between ingress and egress classifier list
(dev->ingress_cl_list and dev->egress_cl_list, latter stored close to
dev->_tx to avoid extra cacheline miss for moderate loads). The egress
part is a bit similar modelled to handle_ing() and patched to a noop in
case the functionality is not used. Both handlers are now called
sch_handle_ingress() and sch_handle_egress(), code sharing among the two
doesn't seem practical as there are various minor differences in both
paths, so that making them conditional in a single handler would rather
slow things down.
Full compatibility to ingress qdisc is provided as well. Since both
piggyback on TC_H_CLSACT, only one of them (ingress/clsact) can exist
per netdevice, and thus ingress qdisc specific behaviour can be retained
for user space. This means, either a user does 'tc qdisc add dev foo ingress'
and configures ingress qdisc as usual, or the 'tc qdisc add dev foo clsact'
alternative, where both, ingress and egress classifier can be configured
as in the below example. ingress qdisc supports attaching classifier to any
minor number whereas clsact has two fixed minors for muxing between the
lists, therefore to not break user space setups, they are better done as
two separate qdiscs.
I decided to extend the sch_ingress module with clsact functionality so
that commonly used code can be reused, the module is being aliased with
sch_clsact so that it can be auto-loaded properly. Alternative would have been
to add a flag when initializing ingress to alter its behaviour plus aliasing
to a different name (as it's more than just ingress). However, the first would
end up, based on the flag, choosing the new/old behaviour by calling different
function implementations to handle each anyway, the latter would require to
register ingress qdisc once again under different alias. So, this really begs
to provide a minimal, cleaner approach to have Qdisc_ops and Qdisc_class_ops
by its own that share callbacks used by both.
Example, adding qdisc:
# tc qdisc add dev foo clsact
# tc qdisc show dev foo
qdisc mq 0: root
qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc clsact ffff: parent ffff:fff1
Adding filters (deleting, etc works analogous by specifying ingress/egress):
# tc filter add dev foo ingress bpf da obj bar.o sec ingress
# tc filter add dev foo egress bpf da obj bar.o sec egress
# tc filter show dev foo ingress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[ingress] direct-action
# tc filter show dev foo egress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[egress] direct-action
A 'tc filter show dev foo' or 'tc filter show dev foo parent ffff:' will
show an empty list for clsact. Either using the parent names (ingress/egress)
or specifying the full major/minor will then show the related filter lists.
Prior work on a mqprio prequeue() facility [1] was done mainly by John Fastabend.

What happens is that on ingress, we push Ethernet header back in, either
from cls_bpf or right before skb_do_redirect(), but without updating csum.
The "hw csum failure" can be fixed by using the new skb_postpush_rcsum()
helper for the dev_forward_skb() case to correct the csum diff again.

====================
Namespaceify tcp keepalive machinery
The following patch series enables the tcp keepalive mechanism
to be configured per net namespace. This is especially useful
if you have multiple containers hosted on one node and one of
them is under DoS- in such situations one thing which could
be done is to configure the tcp keepalive settings such that
connections for that particular container are being reset
faster.
Another scenario where not being able to control those knob
comes per container is problematic is occurs the value of
net.netfilter.nf_conntrack_tcp_timeout_established is set
below the keepalive interval, in such situations the server won't
send an RST packet resulting in applications not trying to
reconnect and stale connection waiting. Changing the global
keepalive value is a possible solution but it might interfere
with other containers.
The three patches gradually convert each of the affected knobs
to be per netns. I thought it would be easier for review than
put everything in one patch. If people deem it more appropriate
to squash everything in one patch (maybe after review) I'd
be more than happy to do it.
The patches have been compile-tested on 4.4 and functionally
tested on 3.12 and they work as expected.

10GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to ixgbe only.
Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration. Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550. Lastly fix the PFC configuration
to include X550 devices.
Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure. This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().
Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set. This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets. Fix this by skipping extended headers
when they are present.
Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.
Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events. Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

Mitch adds a useful error message and return value when the VFs are being

change to allow the user to specify a zero MAC address for VFs, which

Sowmini Varadhan from Oracle adds similar functionality/fix to i40e that
was added to ixgbe earlier. The fix attempts to look up the MAC address
in the Open Firmware on systems that support it and use IDPROM on SPARC
if no OF address is found.

When FCoE is enabled with SR-IOV on the X550 NIC the hardware

This patch fixes these by setting the expected values in the

i40e: Look up MAC address in Open Firmware or IDPROM
This is the i40e equivalent of commit
c762dff24c06 ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").
As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.
In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.
The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.
