2018-06-01net: mvpp2: Split the PPv2 driver to a dedicated directoryMaxime Chevallier
As the mvpp2 driver is growing, move this driver to a dedicated directory and split it into several files. Since this driver has a lot of register defines and structure definitions, it can benefit from having all of this into a dedicated header file, named mvpp2.h. A good chunk of the mvpp2 code is dedicated to Header Parser handling, so we introduce mvpp2_prs.h where all Header Parser definitions are located, and mvpp2_prs.c containing the related code. In the same way, mvpp2_cls.h and mvpp2_cls.c are created to contain Classifier and RSS related code. The former 'mvpp2.c' file is renamed 'mvpp2_main.c' so that we can keep the driver binary named 'mvpp2'. This commit is only about spliting the driver into multiple files and doesn't introduce any new function, feature or fix besides removing 'static' keywords when needed.

2018-06-01net: sched: split tc_ctl_tfilter into three handlersVlad Buslov
tc_ctl_tfilter handles three netlink message types: RTM_NEWTFILTER, RTM_DELTFILTER, RTM_GETTFILTER. However, implementation of this function involves a lot of branching on specific message type because most of the code is message-specific. This significantly complicates adding new functionality and doesn't provide much benefit of code reuse. Split tc_ctl_tfilter to three standalone functions that handle filter new, delete and get requests. The only truly protocol independent part of tc_ctl_tfilter is code that looks up queue, class, and block. Refactor this code to standalone tcf_block_find function that is used by all three new handlers. Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-05-31rtnetlink: Remove VLA usageKees Cook
In the quest to remove all stack VLA usage from the kernel[1], this allocates the maximum size expected for all possible types and adds sanity-checks at both registration and usage to make sure nothing gets out of sync. This matches the proposed VLA solution for nfnetlink[2]. The values chosen here were based on finding assignments for .maxtype and .slave_maxtype and manually counting the enums: slave_maxtype (max 33): IFLA_BRPORT_MAX 33 IFLA_BOND_SLAVE_MAX 9 maxtype (max 45): IFLA_BOND_MAX 28 IFLA_BR_MAX 45 __IFLA_CAIF_HSI_MAX 8 IFLA_CAIF_MAX 4 IFLA_CAN_MAX 16 IFLA_GENEVE_MAX 12 IFLA_GRE_MAX 25 IFLA_GTP_MAX 5 IFLA_HSR_MAX 7 IFLA_IPOIB_MAX 4 IFLA_IPTUN_MAX 21 IFLA_IPVLAN_MAX 3 IFLA_MACSEC_MAX 15 IFLA_MACVLAN_MAX 7 IFLA_PPP_MAX 2 __IFLA_RMNET_MAX 4 IFLA_VLAN_MAX 6 IFLA_VRF_MAX 2 IFLA_VTI_MAX 7 IFLA_VXLAN_MAX 28 VETH_INFO_MAX 2 VXCAN_INFO_MAX 2 This additionally changes maxtype and slave_maxtype fields to unsigned, since they're only ever using positive values.

2018-05-31Merge branch 'bridge-vlan-notify'David S. Miller
Petr Machata says: ==================== net: bridge: Notify about bridge VLANs In commit 946a11e7408e ("mlxsw: spectrum_span: Allow bridge for gretap mirror"), mlxsw got support for offloading mirror-to-gretap such that the underlay packet path involves a bridge. In that case, the offload is also influenced by PVID setting of said bridge. However, changes to VLAN configuration of the bridge itself do not generate switchdev notifications, so there's no mechanism to prod mlxsw to update the offload when these settings change. In this patchset, the problem is resolved by distributing the switchdev notification SWITCHDEV_OBJ_ID_PORT_VLAN also for configuration changes on bridge VLANs. Since stacked devices distribute the notification to lower devices, such event eventually reaches the driver, which can determine whether it's a bridge or port VLAN by inspecting orig_dev. To keep things consistent, the newly-distributed notifications observe the same protocol as the existing ones: dual prepare/commit, with -EOPNOTSUPP indicating lack of support, even though there's currently nothing to prepare for and nothing to support. Correspondingly, all switchdev drivers have been updated to return -EOPNOTSUPP for bridge VLAN notifications. In patches #1 and #2, the code base is changed to support the following additions: functions br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del() are introduced to simplify sending notifications; and br_vlan_add_existing() is introduced to later make it simpler to add error-handling code for the case of configuring a preexisting VLAN on bridge CPU port. In patches #3-#6, respectively for mlxsw, rocker, DSA and DPAA2 ethsw, the new notifications (which are not enabled yet) are ignored to maintain the current behavior. In patch #7, the notification is actually enabled. In patch #8, mlxsw is changed to update offloads of mirror-to-gre also for bridge-related notifications. Changes from v3 to v4: - In patch #1, separate variable declarations from program logic. - Add patch #2. - In patch #7, add error handling around a newly-introduced call to br_switchdev_port_vlan_add(). - Rephrase commit messages of patches #3-#6 to explain motivation for the change. Changes from v2 to v3: - Add a fallback definition for br_switchdev_port_obj_add() and br_switchdev_port_obj_del() when !CONFIG_NET_SWITCHDEV. Changes from v1 to v2: - Rename br_switchdev_port_obj_add() and br_switchdev_port_obj_del() to br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del(), and move from br_vlan.c to br_switchdev.c. ==================== Signed-off-by: David S.

2018-05-31mlxsw: spectrum_switchdev: Schedule respin during trans preparePetr Machata
Since there's no special support for the bridge events, the driver returns -EOPNOTSUPP, and thus the commit never happens. Therefore schedule respin during the prepare stage: there's no real difference one way or another. This fixes the problem that mirror-to-gretap offload wouldn't adapt to changes in bridge vlan configuration right away and another notification would have to arrive for mlxsw to catch up.

2018-05-29Merge branch 'net-Add-address-attribute-to-control-metric-of-prefix-route'David S. Miller
David Ahern says: ==================== net: Add address attribute to control metric of prefix route For use cases such as VRR (Virtual Router Redundancy) interface managers want efficient control over the order of prefix routes when multiple interfaces have addresses with overlapping/duplicate subnets. Currently, if two interfaces have addresses in the same subnet, the order of the prefix route entries is determined by the order in which the addresses are assigned or the links brought up. Any actions like cycling an interface up and down changes that order. This set adds a new attribute for addresses to allow a user to specify the metric of the prefix route associated with an address giving interface managers better and more efficient control of the order of prefix routes. Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config struct. The functions currently have a long list of arguments and adding the metric just makes it worse. Because of the overall diff size in moving the arguments to a struct, the change is done in stages to make it easier to review starting with the bottom function and pushing the struct up to callers in each successive patch. Patch 4 introduces the new attribute. Patches 5 and 6 add support for the new attribute to IPv4 and IPv6 addresses. Patch 7 adds a set of test cases. Patch 8 adds support to iproute2 Changes since RFC - collapsed patches 1 and 3 into patch 2 - simplified stack variables in fib_modify_prefix_metric in patch 5 ==================== Signed-off-by: David S.

2018-05-29net/ipv6: Add support for specifying metric of connected routesDavid Ahern
Add support for IFA_RT_PRIORITY to ipv6 addresses. If the metric is changed on an existing address then the new route is inserted before removing the old one. Since the metric is one of the route keys, the prefix route can not be atomically replaced. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
