2016-10-18net: Introduce new api for walking upper and lower devicesDavid Ahern2-0/+172
This patch introduces netdev_walk_all_upper_dev_rcu, netdev_walk_all_lower_dev and netdev_walk_all_lower_dev_rcu. These functions recursively walk the adj_list of devices to determine all upper and lower devices. The functions take a callback function that is invoked for each device in the list. If the callback returns non-0, the walk is terminated and the functions return that code back to callers. v3 - simplified netdev_has_upper_dev_all_rcu and __netdev_has_upper_dev and removed typecast as suggested by Stephen v2 - fixed definition of netdev_next_lower_dev_rcu to mirror the upper_dev version.

2016-10-18net: Remove refnr arg when inserting link adjacenciesDavid Ahern1-15/+12
Commit 93409033ae65 ("net: Add netdev all_adj_list refcnt propagation to fix panic") propagated the refnr to insert and remove functions tracking the netdev adjacency graph. However, for the insert path the refnr can only be 1. Accordingly, remove the refnr argument to make that clear. ie., the refnr arg in 93409033ae65 was only needed for the remove path.

2016-10-18Merge branch 'bpf-selftests'David S. Miller12-760/+1207
Daniel Borkmann says: ==================== Move to BPF selftests This set improves the test_verifier and test_maps suite and moves it over to a new BPF selftest directory, so we can keep improving it under kernel selftest umbrella. This also integrates a test script for checking test_bpf.ko under various JIT options. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-10-18bpf: add initial suite for selftestsDaniel Borkmann12-765/+1096
Add a start of a test suite for kernel selftests. This moves test_verifier and test_maps over to tools/testing/selftests/bpf/ along with various code improvements and also adds a script for invoking test_bpf module. The test suite can simply be run via selftest framework, f.e.: # cd tools/testing/selftests/bpf/ # make # make run_tests Both test_verifier and test_maps were kind of misplaced in samples/bpf/ directory and we were looking into adding them to selftests for a while now, so it can be picked up by kbuild bot et al and hopefully also get more exposure and thus new test case additions.

2016-10-18Merge branch 'ethernet-use-core-min-max-mtu'David S. Miller102-744/+480
Jarod Wilson says: ==================== ethernet: use core min/max MTU checking Now that the network stack core min/max MTU checking infrastructure is in place, time to start making drivers use it. We'll start with the easiest ones, the ethernet drivers, split roughly by vendor, with a catch-all patch at the end. For the most part, every patch does the same essential thing: removes the MTU range checking from the drivers' ndo_change_mtu function, puts those ranges into the core net_device min_mtu and max_mtu fields, and where possible, removes ndo_change_mtu functions entirely. These patches have all been built through the 0-day build infrastructure provided by Intel, on top of net-next as of October 17. ==================== Signed-off-by: David S.

2016-10-17Merge branch 'mv88e6xxx-interrupt-support'David S. Miller9-38/+522
Andrew Lunn says: ==================== Interrupt support for mv88e6xxx This patchset add interrupt controller support to the MV88E6xxx. This allows access to the interrupts the internal PHY generate. These interrupts can then be associated to a PHY device in the device tree and used by the PHY lib, rather than polling. Since interrupt handling needs to make MDIO bus accesses, threaded interrupts are used. The phylib needs to request the PHY interrupt using the threaded IRQ API. This in term allows some simplification to the code, in that the phylib interrupt handler can directly call phy_change(), rather than use a work queue. The work queue is however retained for the phy_mac_interrupt() call, which can be called in hard interrupt context. Since RFC v1: Keep phy_mac_interrupt() callable in hard IRQ context. The fix to trigger the phy state machine transitions on interrupts has already been submitted, so is dropped from here. Added back shared interrupts support. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2016-10-17net: phy: Use phy name when requesting the interruptAndrew Lunn1-2/+1
Using the fixed name "phy_interrupt" is not very informative in /proc/interrupts when there are a lot of phys, e.g. a device with an Ethernet switch. So when requesting the interrupt, use the name of the phy. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2016-10-17net: phy: Threaded interrupts allow some simplificationAndrew Lunn3-22/+30
The PHY interrupts are now handled in a threaded interrupt handler, which can sleep. The work queue is no longer needed, phy_change() can be called directly. phy_mac_interrupt() still needs to be safe to call in interrupt context, so keep the work queue, and use a helper to call phy_change().

2016-10-17net: phy: Use threaded IRQ, to allow IRQ from sleeping devicesAndrew Lunn1-4/+4
The interrupt lines from PHYs maybe connected to I2C bus expanders, or from switches on MDIO busses. Such interrupts are sourced from devices which sleep, so use threaded interrupts. Threaded interrupts require that the interrupt requester also uses the threaded API. Change the phylib to use the threaded API, which is backwards compatible with none-threaded IRQs.

2016-10-17net: dsa: mv88e6xxx: Implement interrupt support.Andrew Lunn5-12/+438
The switch can have up to two interrupt controllers. One of these contains the interrupts from the integrated PHYs, so is useful to export. The Marvell PHY driver can then be used in interrupt mode, rather than polling, speeding up PHY handling and reducing load on the MDIO bus.

2016-10-17ila: Don't use dest cache when gateway is setTom Herbert1-0/+8
If the gateway is set on an ILA route we don't need to bother with using the destination cache in the ILA route. Translation does not change the routing in this case so we can stick with orig_output in the lwstate output function. Tested: Ran netperf with and without gateway for LWT route.

2016-10-16ipvlan: constify l3mdev_ops structureJulia Lawall1-1/+1
This l3mdev_ops structure is only stored in the l3mdev_ops field of a net_device structure. This field is declared const, so the l3mdev_ops structure can be declared as const also. Additionally drop the __read_mostly annotation. The semantic patch that adds const is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct l3mdev_ops i@p = { ... }; @ok@ identifier r.i; struct net_device *e; position p; @@ e->l3mdev_ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct l3mdev_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct l3mdev_ops i = { ... }; // </smpl> The effect on the layout of the .o file is shown by the following output of the size command, first before then after the transformation: text data bss dec hex filename 7364 466 52 7882 1eca drivers/net/ipvlan/ipvlan_main.o 7412 434 52 7898 1eda drivers/net/ipvlan/ipvlan_main.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.

Tom Herbert says: ==================== ila: Cache a route in ILA lwt structure Add a dst_cache to ila_lwt structure. This holds a cached route for the translated address. In ila_output we now perform a route lookup after translation and if possible (destination in original route is full 128 bits) we set the dst_cache. Subsequent calls to ila_output can then use the cache to avoid the route lookup. This eliminates the need to set the gateway on ILA routes as previously was being done. Now we can do somthing like: ./ip route add 3333::2000:0:0:2/128 encap ila 2222:0:0:2 \ csum-mode neutral-map dev eth0 ## No via needed! Also, add destroy_state to lwt ops.

Users of lwt tunnels may set up some secondary state in build_state function. Add a corresponding destroy_state function to allow users to clean up state. This destroy state function is called from lwstate_free. Also, we now free lwstate using kfree_rcu so user can assume structure is not freed before rcu.
