2025-05-16vsock/test: retry send() to avoid occasional failure in sigpipe testStefano Garzarella
When the other peer calls shutdown(SHUT_RD), there is a chance that the send() call could occur before the message carrying the close information arrives over the transport. In such cases, the send() might still succeed. To avoid this race, let's retry the send() call a few times, ensuring the test is more reliable. Sleep a little before trying again to avoid flooding the other peer and filling its receive buffer, causing false-negative.

2025-05-16Merge branch 'tools-ynl-gen-support-sub-messages-and-rt-link'Jakub Kicinski
Jakub Kicinski says: ==================== tools: ynl-gen: support sub-messages and rt-link Sub-messages are how we express "polymorphism" in YNL. Donald added the support to specs and Python a while back, support them in C, too. Sub-message is a nest, but the interpretation of the attribute types within that nest depends on a value of another attribute. For example in rt-link the "kind" attribute contains the link type (veth, bonding, etc.) and based on that the right enum has to be applied to interpret link-specific attributes. The last message is probably the most interesting to look at, as it adds a fairly advanced sample. This patch only contains enough support for rtnetlink, we will need a little more complexity to support TC, where sub-messages may contain fixed headers, and where the selector may be in a different nest than the submessage. ==================== Link: https://patch.msgid.link/20250515231650.1325372-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Line 4 shows the error with the attribute path correctly generated by YNL. Then sample fixes the bad attribute and re-issues the request, with NLM_F_ECHO set. This flag causes the notification to be looped back to the initiating socket (our socket). Sample parses this notification to save the ifindex of the created netkit. Sample then proceeds to list the devices. Line 8 above shows a dummy device with two alt names. Lines 9 and 10 show the netkit devices the sample itself created. The "primary" and "policy" attrs are from inside the netkit submsg. The string values are auto-generated for the enums by YNL. To clean up sample deletes the interface it created (line 11).

2025-05-16tools: ynl: submsg: reverse parse / error reportingJakub Kicinski
Reverse parsing lets YNL convert bad and missing attr pointers from extack into a string like "missing attribute nest1.nest2.attr_name". It's a feature that's unique to YNL C AFAIU (even the Python YNL can't do nested reverse parsing). Add support for reverse-parsing of sub-messages. To simplify the logic and the code annotate the type policies with extra metadata. Mark the selectors and the messages with the information we need. We assume that key / selector always precedes the sub-message while parsing (and also if there are multiple sub-messages like in rt-link they are interleaved selector 1 ... submsg 1 ... selector 2 .. submsg 2, not selector 1 ... selector 2 ... submsg 1 ... submsg 2). The rt-link sample in a subsequent changes shows reverse parsing of sub-messages in action.

2025-05-16tools: ynl-gen: submsg: support parsing and rendering sub-messagesJakub Kicinski
Adjust parsing and rendering appropriately to make sub-messages work. Rendering is pretty trivial, as the submsg -> netlink conversion looks like rendering a nest in which only one attr was set. Only trick is that we use the enum value of the sub-message rather than the nest as the type, and effectively skip one layer of nesting. A real double nested struct would look like this: [SELECTOR] [SUBMSG] [NEST] [MSG1-ATTR] A submsg "is" the nest so by skipping I mean: [SELECTOR] [SUBMSG] [MSG1-ATTR] There is no extra validation in YNL if caller has set the selector matching the submsg type (e.g. link type = "macvlan" but the nest attrs are set to carry "veth"). Let the kernel handle that. Parsing side is a little more specialized as we need to render and insert a new kind of function which switches between what to parse based on the selector. But code isn't too complicated.

2025-05-16tools: ynl-gen: submsg: render the structsJakub Kicinski
The easiest (or perhaps only sane) way to support submessages in C is to treat them as if they were nests. Build fake attributes to that effect in the codegen. Render the submsg as a big nest of all possible values. With this in place the main missing part is to hook in the switch which selects how to parse based on the key.

2025-05-16vmxnet3: update MTU after device quiesceRonak Doshi
Currently, when device mtu is updated, vmxnet3 updates netdev mtu, quiesces the device and then reactivates it for the ESXi to know about the new mtu. So, technically the OS stack can start using the new mtu before ESXi knows about the new mtu. This can lead to issues for TSO packets which use mss as per the new mtu configured. This patch fixes this issue by moving the mtu write after device quiesce.

2025-05-16net: rfs: add sock_rps_delete_flow() helperEric Dumazet
RFS can exhibit lower performance for workloads using short-lived flows and a small set of 4-tuple. This is often the case for load-testers, using a pair of hosts, if the server has a single listener port. Typical use case : Server : tcp_crr -T128 -F1000 -6 -U -l30 -R 14250 Client : tcp_crr -T128 -F1000 -6 -U -l30 -c -H server | grep local_throughput This is because RFS global hash table contains stale information, when the same RSS key is recycled for another socket and another cpu. Make sure to undo the changes and go back to initial state when a flow is disconnected. Performance of the above test is increased by 22 %, going from 372604 transactions per second to 457773.

2025-05-16bridge: netfilter: Fix forwarding of fragmented packetsIdo Schimmel
When netfilter defrag hooks are loaded (due to the presence of conntrack rules, for example), fragmented packets entering the bridge will be defragged by the bridge's pre-routing hook (br_nf_pre_routing() -> ipv4_conntrack_defrag()). Later on, in the bridge's post-routing hook, the defragged packet will be fragmented again. If the size of the largest fragment is larger than what the kernel has determined as the destination MTU (using ip_skb_dst_mtu()), the defragged packet will be dropped. Before commit ac6627a28dbf ("net: ipv4: Consolidate ipv4_mtu and ip_dst_mtu_maybe_forward"), ip_skb_dst_mtu() would return dst_mtu() as the destination MTU. Assuming the dst entry attached to the packet is the bridge's fake rtable one, this would simply be the bridge's MTU (see fake_mtu()). However, after above mentioned commit, ip_skb_dst_mtu() ends up returning the route's MTU stored in the dst entry's metrics. Ideally, in case the dst entry is the bridge's fake rtable one, this should be the bridge's MTU as the bridge takes care of updating this metric when its MTU changes (see br_change_mtu()). Unfortunately, the last operation is a no-op given the metrics attached to the fake rtable entry are marked as read-only. Therefore, ip_skb_dst_mtu() ends up returning 1500 (the initial MTU value) and defragged packets are dropped during fragmentation when dealing with large fragments and high MTU (e.g., 9k). Fix by moving the fake rtable entry's metrics to be per-bridge (in a similar fashion to the fake rtable entry itself) and marking them as writable, thereby allowing MTU changes to be reflected.

2025-05-16net/mlx5e: Reuse per-RQ XDP buffer to avoid stack zeroing overheadCarolina Jubran
CONFIG_INIT_STACK_ALL_ZERO introduces a performance cost by zero-initializing all stack variables on function entry. The mlx5 XDP RX path previously allocated a struct mlx5e_xdp_buff on the stack per received CQE, resulting in measurable performance degradation under this config. This patch reuses a mlx5e_xdp_buff stored in the mlx5e_rq struct, avoiding per-CQE stack allocations and repeated zeroing. With this change, XDP_DROP and XDP_TX performance matches that of kernels built without CONFIG_INIT_STACK_ALL_ZERO. Performance was measured on a ConnectX-6Dx using a single RX channel (1 CPU at 100% usage) at ~50 Mpps. The baseline results were taken from net-next-6.15. Stack zeroing disabled: - XDP_DROP: * baseline: 31.47 Mpps * baseline + per-RQ allocation: 32.31 Mpps (+2.68%) - XDP_TX: * baseline: 12.41 Mpps * baseline + per-RQ allocation: 12.95 Mpps (+4.30%) Stack zeroing enabled: - XDP_DROP: * baseline: 24.32 Mpps * baseline + per-RQ allocation: 32.27 Mpps (+32.7%) - XDP_TX: * baseline: 11.80 Mpps * baseline + per-RQ allocation: 12.24 Mpps (+3.72%) Reported-by: Sebastiano Miano <mianosebastiano@gmail.com> Reported-by: Samuel Dobron <sdobron@redhat.com> Link: https://lore.kernel.org/all/CAMENy5pb8ea+piKLg5q5yRTMZacQqYWAoVLE1FE9WhQPq92E0g@mail.gmail.com/ Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Dragos Tatulea <dtatulea@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Acked-by: Jesper Dangaard Brouer <hawk@kernel.org> Link: https://patch.msgid.link/1747253032-663457-1-git-send-email-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-05-16NFS: Avoid flushing data while holding directory locks in nfs_rename()Trond Myklebust
The Linux client assumes that all filehandles are non-volatile for renames within the same directory (otherwise sillyrename cannot work). However, the existence of the Linux 'subtree_check' export option has meant that nfs_rename() has always assumed it needs to flush writes before attempting to rename. Since NFSv4 does allow the client to query whether or not the server exhibits this behaviour, and since knfsd does actually set the appropriate flag when 'subtree_check' is enabled on an export, it should be OK to optimise away the write flushing behaviour in the cases where it is clearly not needed.

Implement changes to retrieve the offset of ast_idx/ast_hash values from the PEER_MAP3 event, update the vdev search type to ADDRX, and enable AST lookup in the bank configuration.

2025-05-16wifi: ath12k: use different packet offset for WCN7850Kang Yang
In ath12k_dp_mon_rx_merg_msdus(), will set packet offset to 8. This is a right value for QCN9274. But WCN7850 use different hardware rings for monitor mode because it doesn't have RX MON component. So the packet offset is different. With current offset, upper-layer application will failed to parse the payload correctly. Should use different value for those who don't have RX MON component.
