2018-08-03mlxsw: core_acl_flex_actions: Remove redundant mirror resource destructionNir Dotan
In previous patch mlxsw_afa_resource_del() was added to avoid a duplicate resource detruction scenario. For mirror actions, such duplicate destruction leads to a crash as in: # tc qdisc add dev swp49 ingress # tc filter add dev swp49 parent ffff: \ protocol ip chain 100 pref 10 \ flower skip_sw dst_ip 192.168.101.1 action drop # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 \ flower skip_sw dst_ip 192.168.101.1 action goto chain 100 \ action mirred egress mirror dev swp4 Therefore add a call to mlxsw_afa_resource_del() in mlxsw_afa_mirror_destroy() in order to clear that resource from rule's resources.

Each tc flower rule uses a hidden count action.

2018-08-03mlxsw: core_acl_flex_actions: Remove redundant resource destructionNir Dotan
Some ACL actions require the allocation of a separate resource prior to applying the action itself. When facing an error condition during the setup phase of the action, resource should be destroyed. For such actions the destruction was done twice which is dangerous and lead to a potential crash. The destruction took place first upon error on action setup phase and then as the rule was destroyed. The following sequence generated a crash: # tc qdisc add dev swp49 ingress # tc filter add dev swp49 parent ffff: \ protocol ip chain 100 pref 10 \ flower skip_sw dst_ip 192.168.101.1 action drop # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 \ flower skip_sw dst_ip 192.168.101.1 action goto chain 100 \ action mirred egress mirror dev swp4 Therefore add mlxsw_afa_resource_del() as a complement of mlxsw_afa_resource_add() to add symmetry to resource_list membership handling. Call this from mlxsw_afa_fwd_entry_ref_destroy() to make the _fwd_entry_ref_create() and _fwd_entry_ref_destroy() pair of calls a NOP.

2018-08-03mlxsw: core_acl_flex_actions: Return error for conflicting actionsNir Dotan
Spectrum switch ACL action set is built in groups of three actions which may point to additional actions. A group holds a single record which can be set as goto record for pointing at a following group or can be set to mark the termination of the lookup. This is perfectly adequate for handling a series of actions to be executed on a packet. While the SW model allows configuration of conflicting actions where it is clear that some actions will never execute, the mlxsw driver must block such configurations as it creates a conflict over the single terminate/goto record value. For a conflicting actions configuration such as: # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 \ flower skip_sw dst_ip 192.168.101.1 \ action goto chain 100 \ action mirred egress mirror dev swp4 Where it is clear that the last action will never execute, the mlxsw driver was issuing a warning instead of returning an error. Therefore replace that warning with an error for this specific case.

After introduction of the cited commit, mlx5e_build_nic_params receives the netdevice mtu in order to set the sw_mtu of mlx5e_params. For enhanced IPoIB, the netdevice mtu is not set in this stage, therefore, the initial sw_mtu equals zero. As a result, the hw_mtu of the receive queue will be calculated incorrectly causing traffic issues. To fix this issue, query for port mtu before building the nic params.

2018-07-31net/mlx5e: Fix null pointer access when setting MTU of vport representorAdi Nissim
MTU helper function is used by both conventional mlx5e instances (PF/VF) and the eswitch representors. The representor shouldn't change the nic vport context MTU, the VF is responsible for that. Therefore set_mtu_cb has a null value when changing the representor MTU.

However, the qp number in the qp context is not defined as a required parameter by the FW. Therefore, drivers may choose to not specify the qp number in the qp context for the reset-to-init transition. Thus, we must save the qp number passed in the command input modifier -- which is always present.

2018-07-23can: xilinx_can: fix power management handlingAnssi Hannula
There are several issues with the suspend/resume handling code of the driver: - The device is attached and detached in the runtime_suspend() and runtime_resume() callbacks if the interface is running. However, during xcan_chip_start() the interface is considered running, causing the resume handler to incorrectly call netif_start_queue() at the beginning of xcan_chip_start(), and on xcan_chip_start() error return the suspend handler detaches the device leaving the user unable to bring-up the device anymore. - The device is not brought properly up on system resume. A reset is done and the code tries to determine the bus state after that. However, after reset the device is always in Configuration mode (down), so the state checking code does not make sense and communication will also not work. - The suspend callback tries to set the device to sleep mode (low-power mode which monitors the bus and brings the device back to normal mode on activity), but then immediately disables the clocks (possibly before the device reaches the sleep mode), which does not make sense to me. If a clean shutdown is wanted before disabling clocks, we can just bring it down completely instead of only sleep mode. Reorganize the PM code so that only the clock logic remains in the runtime PM callbacks and the system PM callbacks contain the device bring-up/down logic. This makes calling the runtime PM callbacks during e.g. xcan_chip_start() safe. The system PM callbacks now simply call common code to start/stop the HW if the interface was running, replacing the broken code from before. xcan_chip_stop() is updated to use the common reset code so that it will wait for the reset to complete. Reset also disables all interrupts so do not do that separately. Also, the device_may_wakeup() checks are removed as the driver does not have wakeup support. Tested on Zynq-7000 integrated CAN.
