2021-03-17net: stmmac: add timestamp correction to rid CDC sync errorVoon Weifeng
According to Synopsis DesignWare EQoS Databook, the Clock Domain Cross synchronization error is introduced tue to the clock(GMII Tx/Rx clock) being different at the capture as compared to the PTP clock(clk_ptp_ref_i) that is used to generate the time. The CDC synchronization error is almost equal to 2 times the clock period of the PTP clock(clk_ptp_ref_i). On a Intel Tigerlake platform (with Marvell 88E2110 external PHY): Before applying this patch (with CDC synchronization error): ptp4l[64.044]: rms 8 max 13 freq +30877 +/- 11 delay 216 +/- 0 ptp4l[65.047]: rms 13 max 20 freq +30869 +/- 17 delay 213 +/- 0 ptp4l[66.050]: rms 12 max 20 freq +30857 +/- 11 delay 213 +/- 0 ptp4l[67.052]: rms 11 max 22 freq +30849 +/- 10 delay 215 +/- 0 ptp4l[68.055]: rms 10 max 16 freq +30853 +/- 13 delay 215 +/- 0 ptp4l[69.057]: rms 7 max 13 freq +30848 +/- 9 delay 216 +/- 0 ptp4l[70.060]: rms 8 max 13 freq +30846 +/- 10 delay 216 +/- 0 ptp4l[71.063]: rms 9 max 15 freq +30836 +/- 8 delay 218 +/- 0 After applying this patch (CDC syncrhonization error is taken care of): ptp4l[61.516]: rms 773 max 824 freq +31526 +/- 158 delay 200 +/- 0 ptp4l[62.519]: rms 427 max 596 freq +31668 +/- 39 delay 198 +/- 0 ptp4l[63.522]: rms 113 max 206 freq +31482 +/- 57 delay 198 +/- 0 ptp4l[64.525]: rms 40 max 56 freq +31316 +/- 29 delay 200 +/- 0 ptp4l[65.528]: rms 47 max 56 freq +31255 +/- 17 delay 200 +/- 0 ptp4l[66.531]: rms 26 max 36 freq +31246 +/- 9 delay 200 +/- 0 ptp4l[67.534]: rms 12 max 18 freq +31254 +/- 12 delay 202 +/- 0 ptp4l[68.537]: rms 7 max 12 freq +31263 +/- 10 delay 202 +/- 0 Signed-off-by: Voon Weifeng <weifeng.voon@intel.com> Signed-off-by: Wong Vee Khee <vee.khee.wong@intel.com> Signed-off-by: David S.

Second it flips the logic for the string test so that we exit immediately if we are not looking for the stats strings. Doing this we can avoid unnecessary indentation and line wrapping.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2021-03-16 mlx5 uplink representor netdev persistence. Before this patchset we used to have separate netdevs for Native NIC mode and Switchdev mode (uplink representor netdev), meaning that if user switches modes between Native to Switchdev and vice versa, the driver would cleanup the current netdev representor and create a new one for the new mode, such behavior created an administrative nightmare for users, where users need to be aware of such loss of both data path and control path configurations, e.g. netdev attributes and arp/route tables, where the later is more painful. A simple solution for this is not to replace the netdev in first place and use a single netdev to serve the uplink/physical port whether it is in switchdev mode or native mode. We already have different HW profiles for each netdev mode, in this series we just replace the HW profile on the fly and we keep the same netdev attached. Refactoring: Some refactoring has been made to overcome some technical difficulties 1) The netdev is created with the maximum amount of tx/rx queues to serve the two profiles. 2) Some ndos are not supported in some modes, so we added a mode check for such cases, e.g legacy sriov ndos must be blocked in switchdev mode. 3) Some mlx5 netdev private attributes need to be moved out of profiles and kept in a persistent place, where the netdev is created e.g devlink port and other global HW resources 4) The netdev devlink port is now always registered with the switch id Implementation: the last three patches implement the mechanism now as the netdev can be shared. 5) Don't recreate the netdev on switchdev mode changes 6) Prevent changing switchdev mode when some netdev operations are active, mostly when TC rules are being processed. This is required since the netdev is kept registered while switchdev mode can be changed. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2021-03-16mlxsw: spectrum_acl: Offload FLOW_ACTION_SAMPLEIdo Schimmel
Implement support for action sample when used with a flower classifier by implementing the required sampler_add() / sampler_del() callbacks and registering an Rx listener for the sampled packets. The sampler_add() callback returns an error for Spectrum-1 as the functionality is not supported. In Spectrum-{2,3} the callback creates a mirroring agent towards the CPU. The agent's identifier is used by the policy engine code to mirror towards the CPU with probability. The Rx listener for the sampled packet is registered with the 'policy engine' mirroring reason and passes trapped packets to the psample module after looking up their parameters (e.g., sampling group).

2021-03-16mlxsw: spectrum_matchall: Add support for egress samplingIdo Schimmel
Allow user space to install a matchall classifier with sample action on egress. This is only supported on Spectrum-2 onwards, so Spectrum-1 will continue to return an error. Programming the hardware to sample on egress is identical to ingress sampling with the sole change of using a different sampling trigger. Upon receiving a sampled packet, the sampling trigger (ingress vs. egress) will be encoded in the mirroring reason in the Completion Queue Element (CQE). The mirroring reason is used to lookup the sampling parameters (e.g., psample group) which are passed to the psample module. Note that locally generated packets that are sampled are simply consumed. This is done for several reasons. First, such packets do not have an ingress netdev given that their Rx local port is the CPU port. This breaks several basic assumptions. Second, sampling using the same interface (tc), but with flower classifier will not result in locally generated packets being sampled given that such packets are not subject to the policy engine. Third, realistically, this is not a big deal given that the vast majority of the packets being transmitted through the port are not locally generated packets. Fourth, if such packets do need to be sampled, they can be sampled with a 'skip_hw' filter and reported to the same sampling group as the data path packets. The software sampling rate can also be adjusted to fit the rate of the locally generated packets which is much lower than the rate of the data path traffic.

2021-03-16mlxsw: spectrum: Track sampling triggers in a hash tableIdo Schimmel
Currently, mlxsw supports a single sampling trigger type (i.e., received packet). When sampling is configured on an ingress port, the sampling parameters (e.g., pointer to the psample group) are stored as an attribute of the port, so that they could be passed to psample_sample_packet() when a sampled packet is trapped to the CPU. Subsequent patches are going to add more types of sampling triggers, making it difficult to maintain the current scheme. Instead, store all the active sampling triggers with their associated parameters in a hash table. That way, more trigger types can be easily added. The next patch will flip mlxsw to use the hash table instead of the current scheme. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

2021-03-16net: lapbether: Prevent racing when checking whether the netif is runningXie He
There are two "netif_running" checks in this driver. One is in "lapbeth_xmit" and the other is in "lapbeth_rcv". They serve to make sure that the LAPB APIs called in these functions are called before "lapb_unregister" is called by the "ndo_stop" function. However, these "netif_running" checks are unreliable, because it's possible that immediately after "netif_running" returns true, "ndo_stop" is called (which causes "lapb_unregister" to be called). This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can reliably check and ensure the netif is running while doing their work.
