net: macsec: add support for specifying offload upon link creation

2020-03-30T04:34:21+00:00

This patch adds new netlink attribute to allow a user to (optionally) specify the desired offload mode immediately upon MACSec link creation. Separate iproute patch will be required to support this from user space. Signed-off-by: Mark Starovoytov Signed-off-by: Igor Russkikh Signed-off-by: David S. Miller

net: macsec: introduce the macsec_context structure

2020-01-14T19:31:41+00:00

This patch introduces the macsec_context structure. It will be used in the kernel to exchange information between the common MACsec implementation (macsec.c) and the MACsec hardware offloading implementations. This structure contains pointers to MACsec specific structures which contain the actual MACsec configuration, and to the underlying device (phydev for now).

bonding: add an option to specify a delay between peer notifications

2019-07-04T19:30:48+00:00

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'.
