test_bpf improvements
Please find below the patch series with my latest changes to test_bpf.
The first patch checks for unexpected NULL generated skbs before
running the filter.
The second patch adds the possibility for tests to generate fragmented
skbs.
The third patch tests LD_ABS and LD_IND on fragmented skbs.
The fourth patch adds the possibility to restrict the tests being run
by specifying the name/id/range of the test(s) to run via module
parameters.
The fifth patch tests LD_ABS and LD_IND on non fragmented skbs with
various sizes and alignments.
The sixth and final patch checks that the interpreter or JIT correctly
resets A and X to 0.
This serie is against today's net-next tree.
Changes in V2:
* move declaration of 'ptr' in if() block in patch 2/6.
* fix various typos in patch 4/6
* rework default init of test_range array and cleanup exclude_test()
return condition in patch 4/6.

When developping on the interpreter or a particular JIT, it can be
interesting to restrict the tests list to a specific test or a
particular range of tests.
This patch adds the following module parameters to the test_bpf module:
* test_name=<string>: only the specified named test will be run.
* test_id=<number>: only the test with the specified id will be run
(see the output of test_bpf without parameters to get the test id).
* test_range=<number>,<number>: only the tests within IDs in the
specified id range are run (see the output of test_bpf without
parameters to get the test ids).
Any invalid range, test id or test name will result in -EINVAL being
returned and no tests being run.

net/mlx5e: Driver updates 04-Aug-2015
This patchset introduces two features to the ConnectX-4 driver: Patch 8/8
("Support physical port counters") exposes some hardware counters through
ethtool. Rest of the patches are preparation and usage of what we call
light-weight netdev open/close. Some flows that used to be in the ndo_open/stop
are moved to the PCI probe/remove flows - i.e. we will make the netdev
open/close operations more "light-weight".
The benefits of this change are:
1) Reduce the execution time of the stop/open operations.
2) Avoid saving SW shadows of resource configurations that must
persist through stop/open operations (e.g flow table steering
rules), and avoid deleting/applying them from/to the device upon
netdev stop/open.
3) Avoid synchronizing threads that access those resources with the
netdev stop/open threads.
Instead of create/destroy the resource during netdev open/stop, This patchset
changes the behavior such that upon netdev stop, traffic is redirected to a
"Drop RQ" (a RQ that silently drops, at the NIC HW level all incoming traffic).
After redirecting the traffic, RX/TX software resources could be destroyed.
During netdev open, the RX/TX rings are created and traffic is redirected to
the RX rings.
Patchset was applied and tested over commit ba7591d ("ebpf: add skb->hash to
offset map for usage in {cls, act}_bpf or filters")

Now that TIRs, TISs and flow tables are kept alive while the netdev is
stopped (after executing ndo_stop()) we can do the following
improvements:
- Obsolete the active_vlans SW shadow.
- Do not delete/add flow table rules upon ndo_stop/open.
In addition to simplifying the flow, this change also fastens
the ndo_open/close operations.
- Obsolete synchronization of threads accessing the flow tables
with the netdev stop/open threads.

Generally an RX packet flows through the following objects:
Flow table --> TIR --> RQT --> RQ
Where:
- TIR stands for "Transport Interface Receive", defining the RSS and
LRO paramaters.
- RQT stands for "RQ Table", implementing the RSS indirection table.
- RQ stands for "Receive Queue"
For flows that do not need LRO, nor RSS, the driver made a shortcut to
the above RX flow by pointing to the RQ directly from the TIR, yielding
this flow:
Flow table --> TIR --> RQ
In this commit we remove this shortcut by "inserting" a single-RQ RQT
between the TIR and the RQ, i.e RX packets will reach the same RQ but
will go through an RQT of size 1, pointing to just a single RQ.
This way the RX traffic re-direction to/from the "Drop RQ" will be more
uniform (AKA "one flow"), as it will involve only RQTs re-direction and
no TIRs re-direction.

There are some left over NULL assignments which we can remove. We can
preserve the error code from ip_route_output() instead of always
returning -ENODEV. Also these functions use a mix of gotos and direct
returns. There is no cleanup necessary so I changed the gotos to

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next, they are:
1) A couple of cleanups for the netfilter core hook from Eric Biederman.
2) Net namespace hook registration, also from Eric. This adds a dependency with
the rtnl_lock. This should be fine by now but we have to keep an eye on this
because if we ever get the per-subsys nfnl_lock before rtnl we have may
problems in the future. But we have room to remove this in the future by
propagating the complexity to the clients, by registering hooks for the init
netns functions.
3) Update nf_tables to use the new net namespace hook infrastructure, also from
Eric.
4) Three patches to refine and to address problems from the new net namespace
hook infrastructure.
5) Switch to alternate jumpstack in xtables iff the packet is reentering. This
only applies to a very special case, the TEE target, but Eric Dumazet
reports that this is slowing down things for everyone else. So let's only
switch to the alternate jumpstack if the tee target is in used through a
static key. This batch also comes with offline precalculation of the
jumpstack based on the callchain depth. From Florian Westphal.
6) Minimal SCTP multihoming support for our conntrack helper, from Michal
Kubecek.
7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from Florian

lwtunnel encap is applied for forwarded packets, but not for

overridden in __mkroute_output, unlike it is in __mkroute_input.
The lwtunnel state is correctly set on the rth through the call to
rt_set_nexthop, so all that needs to be done is to override the dst
output function to be lwtunnel_output if there is lwtunnel state
present and it requires output redirection.

Since the introduction of the BPF action in d23b8ad8ab ("tc: add BPF
based action"), late binding was not working as expected. I.e. setting
the action part for a classifier only via 'bpf index <num>', where <num>
is the index of an existing action, is being rejected by the kernel due
to other missing parameters.
It doesn't make sense to require these parameters such as BPF opcodes
etc, as they are not going to be used anyway: in this case, they're just
allocated/parsed and then freed again w/o doing anything meaningful.
Instead, parse and verify the remaining parameters *after* the test on
tcf_hash_check(), when we really know that we're dealing with creation
of a new action or replacement of an existing one and where late binding
is thus irrelevant.
After patch, test case is now working:
FOO="1,6 0 0 4294967295,"
tc actions add action bpf bytecode "$FOO"
tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action bpf index 1
tc actions show action bpf
action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe
index 1 ref 2 bind 1
tc filter show dev foo
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 flowid 1:1 bytecode '1,6 0 0 4294967295'
action order 1: bpf bytecode '1,6 0 0 4294967295' default-action pipe
index 1 ref 2 bind 1
Late binding of a BPF action can be useful for preloading maps (e.g. before
they hit traffic) in case of eBPF programs, or to share a single eBPF action
with multiple classifiers.
