| * devlink: Add helper function for safely copy string paramMoshe Shemesh2018-10-101-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Devlink string param buffer is allocated at the size of DEVLINK_PARAM_MAX_STRING_VALUE. Add helper function which makes sure this size is not exceeded. Renamed DEVLINK_PARAM_MAX_STRING_VALUE to __DEVLINK_PARAM_MAX_STRING_VALUE to emphasize that it should be used by devlink only. The driver should use the helper function instead to verify it doesn't exceed the allowed length.

In case the param type is string devlink should copy the value from driver string buffer to devlink string buffer on devlink_param_driverinit_value_set() and vice-versa on devlink_param_driverinit_value_get().

For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

* devlink: Add support for resource abstractionArkadi Sharshevsky2018-01-161-0/+374
| | | | | | | | | | | | | | | Add support for hardware resource abstraction over devlink. Each resource is identified via id, furthermore it contains information regarding its size and its related sub resources. Each resource can also provide its current occupancy. In some cases the sizes of some resources can be changed, yet for those changes to take place a hot driver reload may be needed. The reload capability will be introduced in the next patch.

* devlink: Add per devlink instance lockArkadi Sharshevsky2018-01-161-59/+77
| | | | | | | | | | | | | This is a preparation before introducing resources and hot reload support. Currently there are two global lock where one protects all devlink access, and the second one protects devlink port access. This patch adds per devlink instance lock which protects the internal members which are the sb/dpipe/ resource/ports. By introducing this lock the global devlink port lock can be discarded.

* devlink: Add IPv6 header for dpipeArkadi Sharshevsky2017-08-311-0/+17
| | | | | | | | | | This will be used by the IPv6 host table which will be introduced in the following patches. The fields in the header are added per-use. This header is global and can be reused by many drivers. Signed-off-by: Arkadi Sharshevsky <arkadis@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
