Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a reference to the DT node, but does not hold a refcount on the node. The simple solution to this is to add the necessary refcounting into the MDIO bus code for all users, ensuring that on registration, the refcount is incremented, and only dropped when the MDIO bus is released. Do this for fwnodes, so we not only fix this for DT, but also other types of firmware nodes as well. Reported-by:

Implement conditional netlink notifications for Qdiscs and classes, which were missing in the initial patches that targeted tc filters and actions. Notifications will only be built after passing a check for 'rtnl_notify_needed()'. For both Qdiscs and classes 'get' operations now call a dedicated notification function as it was not possible to distinguish between 'create' and 'get' before. This distinction is necessary because 'get' always send a notification. Signed-off-by:

Bound actions always return '0' and as of today we rely on '0' being returned in order to properly skip bound actions in tcf_idr_insert_many. In order to further improve maintainability, introduce the ACT_P_BOUND return code. Actions are updated to return 'ACT_P_BOUND' instead of plain '0'. tcf_idr_insert_many is then updated to check for 'ACT_P_BOUND'. Signed-off-by:

This patch focuses on changes to the XDP part of the napi polling routine. 1. Update the `napi_comp` stat only when napi is actually complete. 2. Simplify the code by using a function pointer to the right napi routine (XDP vs non-XDP path) 3. Remove unnecessary local variables. 4. Adjust a debug print to show the processed XDP frame index rather than the pointer. Signed-off-by:

This check is already done in ena_clean_rx_irq() which indirectly calls it. This function is called in napi context and the driver doesn't allow to change the XDP program without performing destruction and reinitialization of napi context (part of ena_down/ena_up sequence). Signed-off-by:

When an XDP program is loaded the existing channels in the driver split into two halves: - The first half of the channels contain RX and TX rings, these queues are used for receiving traffic and sending packets originating from kernel. - The second half of the channels contain only a TX ring. These queues are used for sending packets that were redirected using XDP_TX or XDP_REDIRECT. Referring to the queues in the second half of the channels as "xdp_ring" can be confusing and may give the impression that ENA has the capability to generate an additional special queue. This patch ensures that the xdp_ring field is exclusively used to describe the XDP TX queue that a specific RX queue needs to utilize when forwarding packets with XDP TX and XDP REDIRECT, preserving the integrity of the xdp_ring field in ena_ring.

To avoid de-referencing skb or xdp_frame when we poll for TX completion (where they might not be in the cache), save the total TX packet size in the ena_tx_buffer object representing the packet. Also the 'print_once' field's type was changed from u32 to u8 to allow adding the 'total_tx_size' without changing the total size of the struct. Signed-off-by:

The skb and xdpf pointers cannot be set together in the driver (each TX descriptor can send either an SKB or an XDP frame), and so it makes more sense to put them both in a union. This decreases the overall size of the ena_tx_buffer struct which improves cache locality. Signed-off-by:

This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints. Signed-off-by:

XDP system has a very large footprint in the driver's overall code. makes the whole driver's code much harder to read. Moving XDP code to dedicated files. This patch doesn't make any changes to the code itself and only cut-pastes the code into ena_xdp.c and ena_xdp.h files so the change is purely cosmetic. Signed-off-by:

For example, "source" is a built-it function in bash, but it cannot be used in dash.

In function `tc_dump_tfilter`, the attributes array is parsed via tcf_tfilter_dump_policy which only describes TCA_DUMP_FLAGS. However, the NLA TCA_CHAIN is also accessed with `nla_get_u32`. The access to TCA_CHAIN is introduced in commit 5bc17018 ("net: sched: introduce multichain support for filters") and no nla_policy is provided for parsing at that point. Later on, tcf_tfilter_dump_policy is introduced in commit f8ab1807 ("net: sched: introduce terse dump flag") while still ignoring the fact that TCA_CHAIN needs a check. This patch does that by complementing the policy to allow the access discussed here can be safe as other cases just choose rtm_tca_policy as the parsing policy. Signed-off-by:

Commit 13e59344 ("net: ethtool: add support for symmetric-xor RSS hash") adds a check to the ethtool set_rxnfc operation, which checks the RX flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced with the same commit. It calls the ethtool get_rxfh operation to get the RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is returned. There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which support the ethtool operation set_rxnfc but not get_rxfh. This results in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all these drivers. Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX flow hash. Fixes: 13e59344 ("net: ethtool: add support for symmetric-xor RSS hash") Signed-off-by:
