2021-12-14net: fec: only clear interrupt of handling queue in fec_enet_rx_queue()Joakim Zhang2-1/+4
commit b5bd95d17102b6719e3531d627875b9690371383 upstream. Background: We have a customer is running a Profinet stack on the 8MM which receives and responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from time to time the received PNIO-CM package is "stock" and is only handled when receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from the expected 40 ms and not the 2s delay of the DCERPC-Ping). After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would be handled by different RX queues. The root cause should be driver ack all queues' interrupt when handle a specific queue in fec_enet_rx_queue(). The blamed patch is introduced to receive as much packets as possible once to avoid interrupt flooding. But it's unreasonable to clear other queues'interrupt when handling one queue, this patch tries to fix it.

2021-10-21net: enetc: make sure all traffic classes can send large framesVladimir Oltean1-1/+4
The enetc driver does not implement .ndo_change_mtu, instead it configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU] statically to a large value during probe time. The driver used to configure only the max SDU for traffic class 0, and that was fine while the driver could only use traffic class 0. But with the introduction of mqprio, sending a large frame into any other TC than 0 is broken. This patch fixes that by replicating per traffic class the static configuration done in enetc_configure_port_mac().

2021-09-24net: enetc: fix the incorrect clearing of IF_MODE bitsVladimir Oltean1-2/+1
The enetc phylink .mac_config handler intends to clear the IFMODE field (bits 1:0) of the PM0_IF_MODE register, but incorrectly clears all the other fields instead. For normal operation, the bug was inconsequential, due to the fact that we write the PM0_IF_MODE register in two stages, first in phylink .mac_config (which incorrectly cleared out a bunch of stuff), then we update the speed and duplex to the correct values in phylink .mac_link_up. Judging by the code (not tested), it looks like maybe loopback mode was broken, since this is one of the settings in PM0_IF_MODE which is incorrectly cleared.

(There is special API to initialize comp_ctr: dim_update_sample_with_comps(), and it is currently used only for RDMA.) comp_ctr is used to compute curr_stats->cmps and curr_stats->cpe_ratio (see dim_calc_stats()) which in turn are consumed by the rdma_dim_*() API. Therefore, functionally, the net_dim*() API consumers are not affected. Nevertheless, fix the computation of statistics based on an uninitialized variable, even if the mentioned statistics are not used at the moment.

2021-09-19enetc: Fix illegal access when reading affinity_hintClaudiu Manoil1-4/+1
irq_set_affinity_hit() stores a reference to the cpumask_t parameter in the irq descriptor, and that reference can be accessed later from irq_affinity_hint_proc_show(). Since the cpu_mask parameter passed to irq_set_affinity_hit() has only temporary storage (it's on the stack memory), later accesses to it are illegal. Thus reads from the corresponding procfs affinity_hint file can result in paging request oops. The issue is fixed by the get_cpu_mask() helper, which provides a permanent storage for the cpumask_t parameter.

2021-08-31dpaa2-eth: Replace strlcpy with strscpyJason Wang1-4/+4
The strlcpy should not be used because it doesn't limit the source length. As linus says, it's a completely useless function if you can't implicitly trust the source string - but that is almost always why people think they should use it! All in all the BSD function will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, We prefer using strscpy instead of strlcpy.

Currently dpaa2_switch_takedown has a funny name and does not do the opposite of dpaa2_switch_init, which makes probing fail when we need to handle an -EPROBE_DEFER. A sketch of what dpaa2_switch_init does: dpsw_open dpaa2_switch_detect_features dpsw_reset for (i = 0; i < ethsw->sw_attr.num_ifs; i++) { dpsw_if_disable dpsw_if_set_stp dpsw_vlan_remove_if_untagged dpsw_if_set_tci dpsw_vlan_remove_if } dpsw_vlan_remove alloc_ordered_workqueue dpsw_fdb_remove dpaa2_switch_ctrl_if_setup When dpaa2_switch_takedown is called from the error path of dpaa2_switch_probe(), the control interface, enabled by dpaa2_switch_ctrl_if_setup from dpaa2_switch_init, remains enabled, because dpaa2_switch_takedown does not call dpaa2_switch_ctrl_if_teardown. Since dpaa2_switch_probe might fail due to EPROBE_DEFER of a PHY, this means that a second probe of the driver will happen with the control interface directly enabled. This will trigger a second error: [ 93.273528] fsl_dpaa2_switch dpsw.0: dpsw_ctrl_if_set_pools() failed [ 93.281966] fsl_dpaa2_switch dpsw.0: fsl_mc_driver_probe failed: -13 [ 93.288323] fsl_dpaa2_switch: probe of dpsw.0 failed with error -13 Which if we investigate the /dev/dpaa2_mc_console log, we find out is caused by: [E, ctrl_if_set_pools:2211, DPMNG] ctrl_if must be disabled So make dpaa2_switch_takedown do the opposite of dpaa2_switch_init (in reasonable limits, no reason to change STP state, re-add VLANs etc), and rename it to something more conventional, like dpaa2_switch_teardown.

In the ICE driver, the latter now causes a link failure: aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl': ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config' ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config' aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config' ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset': ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release' ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild': This is a recurring problem in many drivers, and we have discussed it several times befores, without reaching a consensus. I'm providing a link to the previous email thread for reference, which discusses some related problems. To solve the dependency issue better than the 'imply' keyword, introduce a separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver can depend on if it is able to use PTP support when available, but works fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are then prevented from being built-in, the same way as with a 'depends on PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick, but that can be rather confusing when you first see it. Since this should cover the dependencies correctly, the IS_REACHABLE() hack in the header is no longer needed now, and can be turned back into a normal IS_ENABLED() check. Any driver that gets the dependency wrong will now cause a link time failure rather than being unable to use PTP support when that is in a loadable module. However, the two recently added ptp_get_vclocks_index() and ptp_convert_timestamp() interfaces are only called from builtin code with ethtool and socket timestamps, so keep the current behavior by stubbing those out completely when PTP is in a loadable module. This should be addressed properly in a follow-up. As Richard suggested, we may want to actually turn PTP support into a 'bool' option later on, preventing it from being a loadable module altogether, which would be one way to solve the problem with the ethtool interface.

2021-08-09devlink: Set device as early as possibleLeon Romanovsky1-2/+3
All kernel devlink implementations call to devlink_alloc() during initialization routine for specific device which is used later as a parent device for devlink_register(). Such late device assignment causes to the situation which requires us to call to device_register() before setting other parameters, but that call opens devlink to the world and makes accessible for the netlink users. Any attempt to move devlink_register() to be the last call generates the following error due to access to the devlink->dev pointer. [ 8.758862] devlink_nl_param_fill+0x2e8/0xe50 [ 8.760305] devlink_param_notify+0x6d/0x180 [ 8.760435] __devlink_params_register+0x2f1/0x670 [ 8.760558] devlink_params_register+0x1e/0x20 The simple change of API to set devlink device in the devlink_alloc() instead of devlink_register() fixes all this above and ensures that prior to call to devlink_register() everything already set.

2021-08-04dpaa2-switch: no need to check link state right after ndo_openIoana Ciornei1-14/+0
The call to dpaa2_switch_port_link_state_update is a leftover from the time when on DPAA2 platforms the PHYs were started at boot time so when an ifconfig was issued on the associated interface, the link status needed to be checked directly from the ndo_open() callback. This is not needed anymore since we are now properly integrated with the PHY layer thus a link interrupt will come directly from the PHY eventually without the need to call the sync function. Fix this up by removing the call to dpaa2_switch_port_link_state_update. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-07-29dpaa2-switch: offload shared block mirror filters when binding to a portIoana Ciornei3-0/+71
When mirroring rules are added in shared filter blocks, the same mirroring rule has to be configured on all the switch ports that are part of the same block. In case a switch port joins a shared block after mirroring filters have been already added to it, then all the mirror rules should be offloaded to the port. The reverse, removal of mirroring rules, has to be done at block unbind. For this purpose, the dpaa2_switch_block_offload_mirror() and dpaa2_switch_block_unoffload_mirror() functions are added and called upon binding and unbinding a switch port to/from a block.

Unlike all the actions (drop, redirect, trap) already supported by the dpaa2-switch driver, adding mirroring filters in shared blocks is not achieved by a singular ACL entry added in a table shared by the ports.
