2025-03-04net: hns3: make sure ptp clock is unregister and freed if ↵Peiyang Wang
hclge_ptp_get_cycle returns an error During the initialization of ptp, hclge_ptp_get_cycle might return an error and returned directly without unregister clock and free it. To avoid that, call hclge_ptp_destroy_clock to unregist and free clock if hclge_ptp_get_cycle failed.

2025-03-04be2net: fix sleeping while atomic bugs in be_ndo_bridge_getlinkNikolay Aleksandrov
Partially revert commit b71724147e73 ("be2net: replace polling with sleeping in the FW completion path") w.r.t mcc mutex it introduces and the use of usleep_range. The be2net be_ndo_bridge_getlink() callback is called with rcu_read_lock, so this code has been broken for a long time. Both the mutex_lock and the usleep_range can cause the issue Ian Kumlien reported[1]. The call path is: be_ndo_bridge_getlink -> be_cmd_get_hsw_config -> be_mcc_notify_wait -> be_mcc_wait_compl -> usleep_range() [1] https://lore.kernel.org/netdev/CAA85sZveppNgEVa_FD+qhOMtG_AavK9_mFiU+jWrMtXmwqefGA@mail.gmail.com/ Tested-by: Ian Kumlien <ian.kumlien@gmail.com> Fixes: b71724147e73 ("be2net: replace polling with sleeping in the FW completion path") Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Link: https://patch.msgid.link/20250227164129.1201164-1-razor@blackwall.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-02-28caif_virtio: fix wrong pointer check in cfv_probe()Vitaliy Shevtsov
del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked for NULL before calling it, not cfv->vdev. Also the current implementation is redundant because the pointer cfv->vdev is dereferenced before it is checked for NULL. Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before calling del_vqs().

2025-02-28wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifiManish Dharanenthiran
In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath12k_dp_rx_h_undecap_nwifi function for DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and potentially resulting in invalid data access and memory corruption. Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type.

2025-02-28wifi: ath12k: Report proper tx completion status to mac80211Vinith Kumar R
Currently Tx completion for few exception packets are received from firmware and the tx status updated to mac80211. The tx status values of HAL_WBM_REL_HTT_TX_COMP_STATUS_DROP and HAL_WBM_REL_HTT_TX_COMP_STATUS_TTL are considered as tx failure and reported as tx failure to mac80211. But these failure status is due to internal firmware tx drop and these packets were not tried to transmit in the air. In case of mesh this invalid tx status report might trigger mpath broken issue due to increase in mpath fail average. So do not report these tx status as tx failure instead free the skb by calling ieee80211_free_txskb(), and that will be accounted as dropped frame.

2025-02-28net: stmmac: provide set_clk_tx_rate() hookRussell King (Oracle)
Several stmmac sub-drivers which support RGMII follow the same pattern. They calculate the transmit clock rate, and then call clk_set_rate(). Analysis of several implementation documents suggests that the platform is responsible for providing the transmit clock to the DWMAC core's clk_tx_i. The expected rates are: 10Mbps 100Mbps 1Gbps MII 2.5MHz 25MHz RMII 2.5MHz 25MHz GMII 125MHz RGMI 2.5MHz 25MHz 125MHz It seems some platforms require this clock to be manually configured, but there are outputs from the MAC core that indicate the speed, so a platform may use these to automatically configure the clock. Thus, we can't just provide one solution to configure this clock rate. Moreover, the clock may need to be derived from one of several sources depending on the interface mode. Provide a platform hook that is passed the transmit clock, interface mode and speed.

In case syndrome found on same health poll another health report will be triggered. Avoid two health reports on same syndrome by marking this syndrome as already known.

2025-02-27geneve: Allow users to specify source port rangeDaniel Borkmann
Recently, in case of Cilium, we run into users on Azure who require to use tunneling for east/west traffic due to hitting IPAM API limits for Kubernetes Pods if they would have gone with publicly routable IPs for Pods. In case of tunneling, Cilium supports the option of vxlan or geneve. In order to RSS spread flows among remote CPUs both derive a source port hash via udp_flow_src_port() which takes the inner packet's skb->hash into account. For clusters with many nodes, this can then hit a new limitation [0]: Today, the Azure networking stack supports 1M total flows (500k inbound and 500k outbound) for a VM. [...] Once this limit is hit, other connections are dropped. [...] Each flow is distinguished by a 5-tuple (protocol, local IP address, remote IP address, local port, and remote port) information. [...] For vxlan and geneve, this can create a massive amount of UDP flows which then run into the limits if stale flows are not evicted fast enough. One option to mitigate this for vxlan is to narrow the source port range via IFLA_VXLAN_PORT_RANGE while still being able to benefit from RSS. However, geneve currently does not have this option and it spreads traffic across the full source port range of [1, USHRT_MAX]. To overcome this limitation also for geneve, add an equivalent IFLA_GENEVE_PORT_RANGE setting for users. Note that struct geneve_config before/after still remains at 2 cachelines on x86-64. The low/high members of struct ifla_geneve_port_range (which is uapi exposed) are of type __be16. While they would be perfectly fine to be of __u16 type, the consensus was that it would be good to be consistent with the existing struct ifla_vxlan_port_range from a uapi consumer PoV.

2025-02-27net/mlx5e: Avoid a hundred -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in this particular case, we create a new `struct mlx5e_umr_wqe_hdr` to enclose the header part of flexible structure `struct mlx5e_umr_wqe`. This is, all the members except the flexible arrays `inline_mtts`, `inline_klms` and `inline_ksms` in the anonymous union. We then replace the header part with `struct mlx5e_umr_wqe_hdr hdr;` in `struct mlx5e_umr_wqe`, and change the type of the object currently causing trouble `umr_wqe` from `struct mlx5e_umr_wqe` to `struct mlx5e_umr_wqe_hdr` --this last bit gets rid of the flex-array-in-the-middle part and avoid the warnings. Also, no new members should be added to `struct mlx5e_umr_wqe`, instead any new members must be included in the header structure `struct mlx5e_umr_wqe_hdr`. To enforce this, we use `static_assert()`, ensuring that the memory layout of both the flexible structure and the newly created header struct remain consistent. The next step is to refactor the rest of the related code accordingly, which means adding a bunch of `hdr.` wherever needed. Lastly, we use `container_of()` whenever we need to retrieve a pointer to the flexible structure `struct mlx5e_umr_wqe`. So, with these changes, fix 125 of the following warnings: drivers/net/ethernet/mellanox/mlx5/core/en.h:664:48: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-02-27net: gro: decouple GRO from the NAPI layerAlexander Lobakin
In fact, these two are not tied closely to each other. The only requirements to GRO are to use it in the BH context and have some sane limits on the packet batches, e.g. NAPI has a limit of its budget (64/8/etc.). Move purely GRO fields into a new structure, &gro_node. Embed it into &napi_struct and adjust all the references. gro_node::cached_napi_id is effectively the same as napi_struct::napi_id, but to be used on GRO hotpath to mark skbs. napi_struct::napi_id is now a fully control path field. Three Ethernet drivers use napi_gro_flush() not really meant to be exported, so move it to <net/gro.h> and add that include there. napi_gro_receive() is used in more than 100 drivers, keep it in <linux/netdevice.h>. This does not make GRO ready to use outside of the NAPI context yet.
