net: rtnetlink: Add RTM_SETSTATS

2022-03-03T10:37:23+00:00

The offloaded HW stats are designed to allow per-netdevice enablement and disablement. These stats are only accessible through RTM_GETSTATS, and therefore should be toggled by a RTM_SETSTATS message. Add it, and the necessary skeleton handler. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

rtnetlink: add new rtm tunnel api for tunnel id filtering

2022-03-01T08:38:02+00:00

This patch adds new rtm tunnel msg and api for tunnel id filtering in dst_metadata devices. First dst_metadata device to use the api is vxlan driver with AF_BRIDGE family. This and later changes add ability in vxlan driver to do tunnel id filtering (or vni filtering) on dst_metadata devices. This is similar to vlan api in the vlan filtering bridge. this patch includes selinux nlmsg_route_perms support for RTM_*TUNNEL api from Benjamin Poirier.

include/uapi/linux/xfrm.h: Fix XFRM_MSG_MAPPING ABI breakage

2021-09-14T08:31:35+00:00

Commit 2d151d39073a ("xfrm: Add possibility to set the default to block if we have no policy") broke ABI by changing the value of the XFRM_MSG_MAPPING enum item, thus also evading the build-time check in security/selinux/nlmsgtab.c:selinux_nlmsg_lookup for presence of proper security permission checks in nlmsg_xfrm_perms. Fix it by placing XFRM_MSG_SETDEFAULT/XFRM_MSG_GETDEFAULT to the end of the enum, right before __XFRM_MSG_MAX, and updating the nlmsg_xfrm_perms accordingly.

nexthop: Add netlink defines and enumerators for resilient NH groups

2021-03-12T00:12:59+00:00

- RTM_NEWNEXTHOP et.al. that handle resilient groups will have a new nested attribute, NHA_RES_GROUP, whose elements are attributes NHA_RES_GROUP_*. - RTM_NEWNEXTHOPBUCKET et.al. is a suite of new messages that will currently serve only for dumping of individual buckets of resilient next hop groups. For nexthop group buckets, these messages will carry a nested attribute NHA_RES_BUCKET, whose elements are attributes NHA_RES_BUCKET_*. There are several reasons why a new suite of messages is created for nexthop buckets instead of overloading the information on the existing RTM_{NEW,DEL,GET}NEXTHOP messages. First, a nexthop group can contain a large number of nexthop buckets (4k is not unheard of). This imposes limits on the amount of information that can be encoded for each nexthop bucket given a netlink message is limited to 64k bytes. Second, while RTM_NEWNEXTHOPBUCKET is only used for notifications at this point, in the future it can be extended to provide user space with control over nexthop buckets configuration. - The new group type is NEXTHOP_GRP_TYPE_RES. Note that nexthop code is adjusted to bounce groups with that type for now.

net: bridge: vlan: add rtm definitions and dump support

2020-01-15T12:48:17+00:00

This patch adds vlan rtm definitions: - NEWVLAN: to be used for creating vlans, setting options and notifications - DELVLAN: to be used for deleting vlans - GETVLAN: used for dumping vlan information Dumping vlans which can span multiple messages is added now with basic information (vid and flags). We use nlmsg_parse() to validate the header length in order to be able to extend the message with filtering attributes later. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller
