There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim: Rename externally used net_dim members") which has been pulled into your tree in the meantime, but resolution seems not that bad ... getting current bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed just so he's aware of the resolution below: ** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD static int mlx5e_open_cq(struct mlx5e_channel *c, struct dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) ======= int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Resolution is to take the second chunk and rename net_dim_cq_moder into dim_cq_moder. Also the signature for mlx5e_open_cq() in ... drivers/net/ethernet/mellanox/mlx5/core/en.h +977 ... and in mlx5e_open_xsk() ... drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64 ... needs the same rename from net_dim_cq_moder into dim_cq_moder. ** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix)); struct dim_cq_moder icocq_moder = {0, 0}; struct net_device *netdev = priv->netdev; struct mlx5e_channel *c; unsigned int irq; ======= struct net_dim_cq_moder icocq_moder = {0, 0}; >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Take the second chunk and rename net_dim_cq_moder into dim_cq_moder as well. Let me know if you run into any issues. Anyway, the main changes are: 1) Long-awaited AF_XDP support for mlx5e driver, from Maxim. 2) Addition of two new per-cgroup BPF hooks for getsockopt and setsockopt along with a new sockopt program type which allows more fine-grained pass/reject settings for containers. Also add a sock_ops callback that can be selectively enabled on a per-socket basis and is executed for every RTT to help tracking TCP statistics, both features from Stanislav. 3) Follow-up fix from loops in precision tracking which was not propagating precision marks and as a result verifier assumed that some branches were not taken and therefore wrongly removed as dead code, from Alexei. 4) Fix BPF cgroup release synchronization race which could lead to a double-free if a leaf's cgroup_bpf object is released and a new BPF program is attached to the one of ancestor cgroups in parallel, from Roman. 5) Support for bulking XDP_TX on veth devices which improves performance in some cases by around 9%, from Toshiaki. 6) Allow for lookups into BPF devmap and improve feedback when calling into bpf_redirect_map() as lookup is now performed right away in the helper itself, from Toke. 7) Add support for fq's Earliest Departure Time to the Host Bandwidth Manager (HBM) sample BPF program, from Lawrence. 8) Various cleanups and minor fixes all over the place from many others. ==================== Signed-off-by: David S.

* | bonding: add an option to specify a delay between peer notificationsVincent Bernat2019-07-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, gratuitous ARP/ND packets are sent every `miimon' milliseconds. This commit allows a user to specify a custom delay through a new option, `peer_notif_delay'. Like for `updelay' and `downdelay', this delay should be a multiple of `miimon' to avoid managing an additional work queue. The configuration logic is copied from `updelay' and `downdelay'. However, the default value cannot be set using a module parameter: Netlink or sysfs should be used to configure this feature. When setting `miimon' to 100 and `peer_notif_delay' to 500, we can observe the 500 ms delay is respected: 20:30:19.354693 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:19.874892 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:20.394919 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:20.914963 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 In bond_mii_monitor(), I have tried to keep the lock logic readable. The change is due to the fact we cannot rely on a notification to lower the value of `bond->send_peer_notif' as `NETDEV_NOTIFY_PEERS' is only triggered once every N times, while we need to decrement the counter each time. iproute2 also needs to be updated to be able to specify this new attribute through `ip link'.

It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

Single netlink dump messages contain approximately 25 entries each, and this way we can make sure the partial dump tracking mechanism is working properly. While at it, also ensure that no cached routes can be listed after flush, and remove 'sleep 1' calls, they are not actually needed. v7: No changes v6: - Merge this patch into series including fix, as it's also targeted for net-next.
