2023-03-08net: microchip: sparx5: fix deletion of existing DSCP mappingsDaniel Machon1-16/+16
Fix deletion of existing DSCP mappings in the APP table. Adding and deleting DSCP entries are replicated per-port, since the mapping table is global for all ports in the chip. Whenever a mapping for a DSCP value already exists, the old mapping is deleted first. However, it is only deleted for the specified port. Fix this by calling sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be. Reproduce: // Map and remap DSCP value 63 $ dcb app add dev eth0 dscp-prio 63:1 $ dcb app add dev eth0 dscp-prio 63:2 $ dcb app show dev eth0 dscp-prio dscp-prio 63:2 $ dcb app show dev eth1 dscp-prio dscp-prio 63:1 63:2 <-- 63:1 should not be there Fixes: 8dcf69a64118 ("net: microchip: sparx5: add support for offloading dscp table") Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: David S.

2023-03-01net: lan966x: Fix port police support using tc-matchallHoratiu Vultur1-1/+1
When the police was removed from the port, then it was trying to remove the police from the police id and not from the actual police index. The police id represents the id of the police and police index represents the position in HW where the police is situated. The port police id can be any number while the port police index is a number based on the port chip port. Fix this by deleting the police from HW that is situated at the police index and not police id.

Check all ports instead of just port_count ports. PTP init was only checking ports 0 to port_count. If the hardware ports are not mapped starting from 0 then they would be missed, e.g. if only ports 20-30 were mapped it would attempt to init ports 0-10, resulting in NULL pointers when attempting to timestamp. Now it will init all mapped ports.

Add support for configuring PSFP stream gates (IEEE 802.1Q-2018, 8.6.5.1.2). Stream gates are time-based policers used by PSFP. Frames are dropped based on the gate state (OPEN/ CLOSE), whose state will be altered based on the Gate Control List (GCL) and current PTP time. Apart from time-based policing, stream gates can alter egress queue selection for the frames that pass through the Gate. This is done through Internal Priority Selector (IPS). Stream gates are mapped from stream filters. Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: David S.

2023-01-27lan966x: execute xdp_do_flush() before napi_complete_done()Magnus Karlsson1-3/+3
Make sure that xdp_do_flush() is always executed before napi_complete_done(). This is important for two reasons. First, a redirect to an XSKMAP assumes that a call to xdp_do_redirect() from napi context X on CPU Y will be followed by a xdp_do_flush() from the same napi context and CPU. This is not guaranteed if the napi_complete_done() is executed before xdp_do_flush(), as it tells the napi logic that it is fine to schedule napi context X on another CPU. Details from a production system triggering this bug using the veth driver can be found following the first link below. The second reason is that the XDP_REDIRECT logic in itself relies on being inside a single NAPI instance through to the xdp_do_flush() call for RCU protection of all in-kernel data structures. Details can be found in the second link below.
