02b34d03 - netdevsim: add dummy macsec offload

Thu, 13 Jul 2023 13:20:23 +0000

netdevsim: add dummy macsec offloadWhen the kernel is compiled with MACsec support, add theNETIF_F_HW_MACSEC feature to netdevsim devices and implementmacsec_ops.To allow easy testing of failure from the device, support is limitedto 3 SecY's per netdevsim device, and 1 RXSC per SecY.v2: - nsim_macsec_add_secy, return -ENOSPC if secy_count isn't full but we can't find an empty slot (Simon Horman) - add sci_to_cpu to make sparse happy (Simon Horman) - remove set but not used secy variable (kernel test robot and Simon Horman)Signed-off-by: Sabrina Dubroca Reviewed-by: Simon Horman Signed-off-by: David S.

1a6d7ae7 - netdevsim: Introduce support for L3 offload xstats

Mon, 14 Mar 2022 14:01:15 +0000

netdevsim: Introduce support for L3 offload xstatsAdd support for testing of HW stats support that was added recently, namelythe L3 stats support. L3 stats are provided for devices for which the L3stats have been turned on, and that were enabled for netdevsim through adebugfs toggle: # echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/enable_ifindexFor fully enabled netdevices, netdevsim counts 10pps of ingress traffic and20pps of egress traffic. Similarly, L3 stats can be disabled for a givendevice, and netdevsim ceases pretending there is any HW traffic going on: # echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/disable_ifindexBesides this, there is a third toggle to mark a device for future failure: # echo $ifindex > /sys/kernel/debug/netdevsim/$DEV/hwstats/l3/fail_next_enableA future request to enable L3 stats on such netdevice will be bounced bynetdevsim: # ip -j l sh dev d | jq '.[].ifindex' 66 # echo 66 > /sys/kernel/debug/netdevsim/netdevsim10/hwstats/l3/enable_ifindex # echo 66 > /sys/kernel/debug/netdevsim/netdevsim10/hwstats/l3/fail_next_enable # ip stats set dev d l3_stats on Error: netdevsim: Stats enablement set to fail.Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Acked-by: Jakub Kicinski Signed-off-by: Paolo Abeni List of files: /linux-6.15/drivers/net/netdevsim/Makefile

a8700c3d - netdevsim: Add dummy psample implementation

Sun, 14 Mar 2021 12:19:32 +0000

netdevsim: Add dummy psample implementationAllow netdevsim to report "sampled" packets to the psample module byperiodically generating packets from a work queue. The behavior can beenabled / disabled (default) and the various meta data attributes can becontrolled via debugfs knobs.This implementation enables both testing of the psample module with allthe optional attributes as well as development of user spaceapplications on top of psample such as hsflowd and a Wireshark dissectorfor psample generic netlink packets.Signed-off-by: Ido Schimmel Signed-off-by: David S.

37923ed6 - netdevsim: Add simple FIB resource controller via devlink

Wed, 28 Mar 2018 01:22:00 +0000

netdevsim: Add simple FIB resource controller via devlinkAdd devlink support to netdevsim and use it to implement a simple,profile based resource controller. Only one controller is neededper namespace, so the first netdevsim netdevice in a namespaceregisters with devlink. If that device is deleted, the resourcesettings are deleted.The resource controller allows a user to limit the number of IPv4 andIPv6 FIB entries and FIB rules. The resource paths are: /IPv4 /IPv4/fib /IPv4/fib-rules /IPv6 /IPv6/fib /IPv6/fib-rulesThe IPv4 and IPv6 top level resources are unlimited in size and can notbe changed. From there, the number of FIB entries and FIB rule entriesare unlimited by default. A user can specify a limit for the fib andfib-rules resources: $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 96 $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib-rules size 16 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib size 64 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib-rules size 16 $ devlink dev reload netdevsim/netdevsim0such that the number of rules or routes is limited (96 ipv4 routes in theexample above): $ for n in $(seq 1 32); do ip ro add 10.99.$n.0/24 dev eth1; done Error: netdevsim: Exceeded number of supported fib entries. $ devlink resource show netdevsim/netdevsim0 netdevsim/netdevsim0: name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables non resources: name fib size 96 occ 96 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables ...With this template in place for resource management, it is fairly trivialto extend and shows one way to implement a simple counter based resourcecontroller typical of network profiles.Currently, devlink only supports initial namespace. Code is in place toadapt netdevsim to a per namespace controller once the network namespaceissues are resolved.Signed-off-by: David Ahern Signed-off-by: David S.
