All the map backends are of generic nature. In order to avoid
adding much special code into the eBPF core, rewrite part of
the bpf_prog_array map code and make it more generic. So the
new perf_event_array map type can reuse most of code with
bpf_prog_array map and add fewer lines of special code.

eBPF programs
This patch add three core perf APIs:
- perf_event_attrs(): export the struct perf_event_attr from struct
perf_event;
- perf_event_get(): get the struct perf_event from the given fd;
- perf_event_read_local(): read the events counters active on the
current CPU;
These APIs are needed when accessing events counters in eBPF programs.
The API perf_event_read_local() comes from Peter and I add the
corresponding SOB.

net: dsa: mv88e6xxx: support switchdev FDB objects
This patchset refactors the DSA and mv88e6xxx code to use the switchdev FDB
objects.
The first two patches add minor but necessary changes to switchdev, the third
one implements the switchdev glue in DSA for FDB routines, and the remaining
ones refactor the FDB access functions in the mv88e6xxx code.
Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to br1):
# bridge fdb add 3c:97:0e:11:30:6e dev swp2
# bridge fdb add 3c:97:0e:11:40:78 dev swp3
# bridge fdb add 3c:97:0e:11:50:86 dev swp4
# bridge fdb del 3c:97:0e:11:40:78 dev swp3
# bridge fdb
01:00:5e:00:00:01 dev eth0 self permanent
01:00:5e:00:00:01 dev eth1 self permanent
00:50:d2:10:78:15 dev swp0 master br0 permanent
3c:97:0e:11:30:6e dev swp2 self static
00:50:d2:10:78:15 dev swp3 master br1 permanent
3c:97:0e:11:50:86 dev swp4 self static
# cat /sys/kernel/debug/dsa0/atu
# DB T/P Vec State Addr
# 001 Port 004 e 3c:97:0e:11:30:6e
# 004 Port 010 e 3c:97:0e:11:50:86
For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for non-bridged
ports and bridge groups, and the remaining will be later used by VLANs.
This change is necessary to welcome the support for hardware VLANs (which will
follow soon).
Changes in v2:
- remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code
- use ether_addr_copy instead of memcpy for MAC addresses
- constify MAC address in port_fdb_{add,del}
- split the mv88e6xxx code refactoring into several patches

This commit adds a low level _mv88e6xxx_atu_getnext function and helpers
to rewrite the mv88e6xxx_port_fdb_getnext operation.
A mv88e6xxx_atu_entry structure is added for convenient access to the
hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value.
The previous implementation did not handle the eventual trunk mapping.
If the related bit is set, then the ATU data register would contain the
trunk ID, and not the port vector.
Check this in the FDB getnext operation and do not handle it (yet).

The driver currently manages one FID per port (or bridge group), with a
mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.
The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
FID 0 means that multiple address databases are not being used).
This patch changes the fid_mask for an fid_bitmap of 4096 bits.
>From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
bridge groups (a bridge group gets the FID of its first member). The
remaining bits will be reserved for VLAN entries.

There is a race condition in store_rps_map that allows jump label
count in rps_needed to go below zero. This can happen when
concurrently attempting to set and a clear map.
Scenario:
1. rps_needed count is zero
2. New map is assigned by setting thread, but rps_needed count _not_ yet
incremented (rps_needed count still zero)
2. Map is cleared by second thread, old_map set to that just assigned
3. Second thread performs static_key_slow_dec, rps_needed count now goes
negative
Fix is to increment or decrement rps_needed under the spinlock.

RDS-TCP: Network namespace support
This patch series contains the set of changes to correctly set up
the infra for PF_RDS sockets that use TCP as the transport in multiple
network namespaces.
Patch 1 in the series is the minimal set of changes to allow
a single instance of RDS-TCP to run in any (i.e init_net or other) net
namespace. The changes in this patch set ensure that the execution of
'modprobe [-r] rds_tcp' sets up the kernel TCP sockets
relative to the current netns, so that RDS applications can send/recv
packets from that netns, and the netns can later be deleted cleanly.
Patch 2 of the series further allows multiple RDS-TCP instances,
one per network namespace. The changes in this patch allows dynamic
creation/tear-down of RDS-TCP client and server sockets across all
current and future namespaces.
v2 changes from RFC sent out earlier:
David Ahern comments in patch 1, net_device notifier in patch 2,
patch 3 broken off and submitted separately.

Register pernet subsys init/stop functions that will set up
and tear down per-net RDS-TCP listen endpoints. Unregister
pernet subusys functions on 'modprobe -r' to clean up these
end points.
Enable keepalive on both accept and connect socket endpoints.
The keepalive timer expiration will ensure that client socket
endpoints will be removed as appropriate from the netns when
an interface is removed from a namespace.
Register a device notifier callback that will clean up all
sockets (and thus avoid the need to wait for keepalive timeout)
when the loopback device is unregistered from the netns indicating
that the netns is getting deleted.

The pr_debug family of functions turns into a no-op when -DDEBUG is not
specified, opting instead to call "no_printk", which gets compiled to a
no-op (but retains gcc's nice warnings about printf-style arguments).
The problem with net_dbg_ratelimited is that it is defined to be a
variant of net_ratelimited_function, which expands to essentially:
if (net_ratelimit())
pr_debug(fmt, ...);
When DEBUG is not defined, then this becomes,
if (net_ratelimit())
;
This seems benign, except it isn't. Firstly, there's the obvious
overhead of calling net_ratelimit needlessly, which does quite some book
keeping for the rate limiting. Given that the pr_debug and
net_dbg_ratelimited family of functions are sprinkled liberally through
performance critical code, with developers assuming they'll be compiled
out to a no-op most of the time, we certainly do not want this needless
book keeping. Secondly, and most visibly, even though no debug message
is printed when DEBUG is not defined, if there is a flood of
invocations, dmesg winds up peppered with messages such as
"net_ratelimit: 320 callbacks suppressed". This is because our
aforementioned net_ratelimit() function actually prints this text in
some circumstances. It's especially odd to see this when there isn't any
other accompanying debug message.
So, in sum, it doesn't make sense to have this function's current
behavior, and instead it should match what every other debug family of
functions in the kernel does with !DEBUG -- nothing.
This patch replaces calls to net_dbg_ratelimited when !DEBUG with
no_printk, keeping with the idiom of all the other debug print helpers.
Also, though not strictly neccessary, it guards the call with an if (0)
so that all evaluation of any arguments are sure to be compiled out.

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

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")

- Do not delete/add flow table rules upon ndo_stop/open.
In addition to simplifying the flow, this change also fastens

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.

Dave,
Please consider applying this series to `net-next'.
Do notice that this involves non-networking driver changes -
but sending this as a single series seemed like the best approach as
we had to have bnx2x changes to support the new functionality.
If this is problematic, please tell us what's the preferred solution here.

If there was no overflow, use the first value.
If there was an overflow, read systimeh again and use the second
systimel value.
