The context info allows continuing DUMP requests, shall they fill the netlink buffer. In the case of filtered DUMP requests, a reference on the netdev is grabbed in the .start() callback and release in .done(). Unfiltered DUMP request don't need the dev pointer to be set in the context info, doing so will trigger an unwanted netdev_put() in .done().

Ido Schimmel says: ==================== net: fib_rules: Add DSCP selector support Currently, the kernel rejects IPv4 FIB rules that try to match on the upper three DSCP bits: # ip -4 rule add tos 0x1c table 100 # ip -4 rule add tos 0x3c table 100 Error: Invalid tos. The reason for that is that historically users of the FIB lookup API only populated the lower three DSCP bits in the TOS field of the IPv4 flow key ('flowi4_tos'), which fits the TOS definition from the initial IPv4 specification (RFC 791). This is not very useful nowadays and instead some users want to be able to match on the six bits DSCP field, which replaced the TOS and IP precedence fields over 25 years ago (RFC 2474). In addition, the current behavior differs between IPv4 and IPv6 which does allow users to match on the entire DSCP field using the TOS selector. Recent patchsets made sure that callers of the FIB lookup API now populate the entire DSCP field in the IPv4 flow key. Therefore, it is now possible to extend FIB rules to match on DSCP. This is done by adding a new DSCP attribute which is implemented for both IPv4 and IPv6 to provide user space programs a consistent behavior between both address families. The behavior of the old TOS selector is unchanged and IPv4 FIB rules using it will only match on the lower three DSCP bits. The kernel will reject rules that try to use both selectors. Patch #1 adds the new DSCP attribute but rejects its usage. Patches #2-#3 implement IPv4 and IPv6 support. Patch #4 allows user space to use the new attribute. Patches #5-#6 add selftests. ==================== Link: https://patch.msgid.link/20240911093748.3662015-1-idosch@nvidia.comSigned-off-by: -

Now that both IPv4 and IPv6 support the new DSCP selector, enable user space to configure FIB rules that make use of it by changing the policy of the new DSCP attribute so that it accepts values in the range of [0, 63]. Use NLA_U8 rather than NLA_UINT as the field is of fixed size. Signed-off-by:

Implement support for the new DSCP selector that allows IPv6 FIB rules to match on the entire DSCP field. This is done despite the fact that the above can be achieved using the existing TOS selector, so that user space program will be able to work with IPv4 and IPv6 rules in the same way. Differentiate between both selectors by adding a new bit in the IPv6 FIB rule structure that is only set when the 'FRA_DSCP' attribute is specified by user space. Reject rules that use both selectors. Signed-off-by:

Ido Schimmel authored
The FIB rule TOS selector is implemented differently between IPv4 and IPv6. In IPv4 it is used to match on the three "Type of Services" bits specified in RFC 791, while in IPv6 is it is used to match on the six DSCP bits specified in RFC 2474. Add a new FIB rule attribute to allow matching on DSCP. The attribute will be used to implement a 'dscp' selector in ip-rule with a consistent behavior between IPv4 and IPv6. For now, set the type of the attribute to 'NLA_REJECT' so that user space will not be able to configure it. This restriction will be lifted once both IPv4 and IPv6 support the new attribute.

The enetc driver uses ifdefs when checking whether CONFIG_FSL_ENETC_PTP_CLOCK is enabled in a number of places. This works if the driver is built-in but fails if the driver is available as a kernel module. Replace the instances of ifdef with use of the IS_ENABLED macro, that will evaluate as true when this feature is built as a kernel module and follows the kernel's coding style. Reviewed-by:

When CONFIG_TRACEPOINTS=y but CONFIG_PAGE_POOL=n, we end up with this build failure that is reported by the 0-day bot: ld: vmlinux.o: in function `mp_dmabuf_devmem_alloc_netmems': >> (.text+0xc37286): undefined reference to `__tracepoint_page_pool_state_hold' >> ld: (.text+0xc3729a): undefined reference to `__SCT__tp_func_page_pool_state_hold' >> ld: vmlinux.o:(__jump_table+0x10c48): undefined reference to `__tracepoint_page_pool_state_hold' >> ld: vmlinux.o:(.static_call_sites+0xb824): undefined reference to `__SCK__tp_func_page_pool_state_hold' The root cause is that in this configuration, traces are enabled but the page_pool specific trace_page_pool_state_hold is not registered. There is no reason to build the dmabuf memory provider when CONFIG_PAGE_POOL is not present, as it's really a provider to the page_pool. In fact the whole NET_DEVMEM is RX path-only at the moment, so we can make the entire config dependent on the PAGE_POOL. Note that this may need to be revisited after/while devmem TX is added, as devmem TX likely does not need CONFIG_PAGE_POOL. For now this build fix is sufficient. Reported-by:

So far we have been using only one queue (i.e. default flow) for all RX traffic. This series adds multi-queue support. The driver starts with 1 RX queue by default. User can increase the RX queues via ethtool, e.g. 'ethtool -L ethx rx <N>' The series also adds regmap and regfield support to some of the ALE registers. It adds Policer/Classifier registers and fields. Converting the existing ALE control APIs to regfields can be a separate exercise. Some helper functions are added to read/write to the Policer/Classifier registers and a default Classifier setup function is added that routes packets based on their PCP/DSCP priority to different RX queues.

The Policer registers in the ALE register space are just shadow registers and use an index field in the policer table control register to read/write to the actual Polier registers. Add helper functions to Read and Write to Policer registers. Also add a helper function to set the thread value to classifier/policer mapping. Any packet that first matches the classifier will be sent to the thread (flow) that is set in the classifier to thread mapping table. If not set then it goes to the default flow. Default behaviour is to have 8 classifiers to map 8 DSCP/PCP priorities to N receive threads (flows). N depends on number of RX channels enabled for the port. As per the standard [1] User prioritie 1 (Background) and 2 (Spare) have lower priority than the user priority 0 (default). User priority 1 being of the lowest priority.

am65-cpsw can support up to 8 queues at Rx. Use a macro AM65_CPSW_MAX_RX_QUEUES to indicate that. As there is only one DMA channel for RX traffic, the 8 queues come as 8 flows in that channel. By default, we will start with 1 flow as defined by the macro AM65_CPSW_DEFAULT_RX_CHN_FLOWS. User can change the number of flows by ethtool like so 'ethtool -L ethx rx <N>' All traffic will still come on flow 0. To get traffic on different flows the Classifiers will need to be set up.
