netdevsim: make debug dirs' dentries static

2018-07-27T04:28:54Z

The root directories of netdevsim should only be used by the core to create per-device subdirectories, so limit their visibility to the core file. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: David S. Miller

bpf: offload: keep the offload state per-ASIC

2018-07-18T13:10:34Z

Create a higher-level entity to represent a device/ASIC to allow programs and maps to be shared between device ports. The extra work is required to make sure we don't destroy BPF objects as soon as the netdev for which they were loaded gets destroyed, as other ports may still be using them. When netdev goes away all of its BPF objects will be moved to other netdevs of the device, and only destroyed when last netdev is unregistered.

netdevsim: associate bound programs with shared dev

2018-07-18T13:10:33Z

Move bound program information from netdevsim to shared sub-object, as programs will soon be shared between netdevs of the same ASIC. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add shared netdevsim devices

2018-07-18T13:10:33Z

Factor out sharable netdevsim sub-object and use IFLA_LINK to link netdevsims together at creation time. Sharable object will have its own DebugFS directory. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add switch_id attribute

2018-07-18T13:10:33Z

Grouping netdevsim devices into "ASICs" will soon be supported. Add switch_id attribute to all netdevsims. For now each netdevsim will have its switch_id matching the device id. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add support for simultaneous driver and hw XDP

2018-07-13T18:26:35Z

Allow netdevsim to accept driver and offload attachment of XDP BPF programs at the same time. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

xdp: factor out common program/flags handling from drivers

2018-07-13T18:26:35Z

Basic operations drivers perform during xdp setup and query can be moved to helpers in the core. Encapsulate program and flags into a structure and add helpers. Note that the structure is intended as the "main" program information source in the driver. Most drivers will additionally place the program pointer in their fast path or ring structures. The helpers don't have a huge impact now, but they will decrease the code duplication when programs can be installed in HW and driver at the same time. Encapsulating the basic operations in helpers will hopefully also reduce the number of changes to drivers which adopt them. Helpers could really be static inline, but they depend on definition of struct netdev_bpf which means they'd have to be placed in netdevice.h, an already 4500 line header.
