2025-11-12net: stmmac: improve ndev->max_mtu setup readabilityRussell King (Oracle)
Improve the readibility of the code setting ndev->max_mtu. This depends on the hardware specific maximum defined by the MAC core, and also a platform provided maximum. The code was originally checking that the platform specific maximum was between ndev->min_mtu..MAC core maximum before reducing ndev->max_mtu, otherwise if the platform specific maximum was less than ndev->min_mtu, issuing a warning. Re-order the code to handle the case where the platform specific max is below ndev->min_mtu, which then means that the subsequent test is simply reducing ndev->max_mtu. Update the comment, and add a few blank lines to separate the blocks of code.

2025-11-12selftests/vsock: speed up tests by reducing the QEMU pidfile timeoutBobby Eshleman
Reduce the time waiting for the QEMU pidfile from three minutes to five seconds. The three minute time window was chosen to make sure QEMU had enough time to fully boot up. This, however, is an unreasonably long delay for QEMU to write the pidfile, which happens earlier when the QEMU process starts (not after VM boot). The three minute delay becomes noticeably wasteful in future tests that expect QEMU to fail and wait a full three minutes for a pidfile that will never exist.

2025-11-12selftests/vsock: avoid multi-VM pidfile collisions with QEMUBobby Eshleman
Change QEMU to use generated pidfile names instead of just a single globally-defined pidfile. This allows multiple QEMU instances to co-exist with different pidfiles. This is required for future tests that use multiple VMs to check for CID collissions. Additionally, this also places the burden of killing the QEMU process and cleaning up the pidfile on the caller of vm_start(). To help with this, a function terminate_pidfiles() is introduced that callers use to perform the cleanup. The terminate_pidfiles() function supports multiple pidfile removals because future patches will need to process two pidfiles at a time. Change QEMU_OPTS to be initialized inside the vm_start(). This allows the generated pidfile to be passed to the string assignment, and prepares for future vm-specific options as well (e.g., cid).

2025-11-12selftests/vsock: improve logging in vmtest.shBobby Eshleman
Improve usability of logging functions. Remove the test name prefix from logging functions so that logging calls can be made deeper into the call stack without passing down the test name or setting some global. Teach log function to accept a LOG_PREFIX variable to avoid unnecessary argument shifting. Remove log_setup() and instead use log_host(). The host/guest prefixes are useful to show whether a failure happened on the guest or host side, but "setup" doesn't really give additional useful information. Since all log_setup() calls happen on the host, lets just use log_host() instead.

Saeed Mahameed says: ==================== devlink eswitch inactive mode Before having traffic flow through an eswitch, a user may want to have the ability to block traffic towards the FDB until FDB is fully programmed and the user is ready to send traffic to it. For example: when two eswitches are present for vports in a multi-PF setup, one eswitch may take over the traffic from the other when the user chooses. Before this take over, a user may want to first program the inactive eswitch and then once ready redirect traffic to this new eswitch. This series introduces a user-configurable mode for an eswitch that allows dynamically switching between active and inactive modes. When inactive, traffic does not flow through the eswitch. While inactive, steering pipeline configuration can be done (e.g. adding TC rules, discovering representors, enabling the desired SDN modes such as bridge/OVS/DPDK/etc). Once configuration is completed, a user can set the eswitch mode to active and have traffic flow through. This allows admins to upgrade forwarding pipeline rules with very minimal downtime and packet drops. A user can start the eswitch in switchdev or switchdev_inactive mode. Active: Traffic is enabled on this eswitch FDB. Inactive: Traffic is ignored/dropped on this eswitch FDB.

2025-11-11tools: ynltool: create skeleton for the C commandJakub Kicinski
Based on past discussions it seems like integration of YNL into iproute2 is unlikely. YNL itself is not great as a C library, since it has no backward compat (we routinely change types). Most of the operations can be performed with the generic Python CLI directly. There is, however, a handful of operations where summarization of kernel output is very useful (mostly related to stats: page-pool, qstat). Create a command (inspired by bpftool, I think it stood the test of time reasonably well) to be able to plug the subcommands into.

2025-11-11wifi: mac80211: track MU-MIMO configuration on disabled interfacesBenjamin Berg
For monitoring, userspace will try to configure the VIF sdata, while the driver may see the monitor_sdata that is created when only monitor interfaces are up. This causes the odd situation that it may not be possible to store the MU-MIMO configuration on monitor_sdata. Fix this by storing that information on the VIF sdata and updating the monitor_sdata when available and the interface is up. Also, adjust the code that adds monitor_sdata so that it will configure MU-MIMO based on the newly added interface or one of the existing ones. This should give a mostly consistent behaviour when configuring MU-MIMO on sniffer interfaces. Should the user configure MU-MIMO on multiple sniffer interfaces, then mac80211 will simply select one of the configurations. This behaviour should be good enough and avoids breaking user expectations in the common scenarios.

2025-11-11xsk: add indirect call for xsk_destruct_skbJason Xing
Since Eric proposed an idea about adding indirect call wrappers for UDP and managed to see a huge improvement[1], the same situation can also be applied in xsk scenario. This patch adds an indirect call for xsk and helps current copy mode improve the performance by around 1% stably which was observed with IXGBE at 10Gb/sec loaded. If the throughput grows, the positive effect will be magnified. I applied this patch on top of batch xmit series[2], and was able to see <5% improvement from our internal application which is a little bit unstable though. Use INDIRECT wrappers to keep xsk_destruct_skb static as it used to be when the mitigation config is off. Be aware of the freeing path that can be very hot since the frequency can reach around 2,000,000 times per second with the xdpsock test.

2025-11-10isdn: kcapi: add WQ_PERCPU to alloc_workqueue usersMarco Crivellari
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default.

Ankit Garg says: ==================== gve: Improve RX buffer length management This patch series improves the management of the RX buffer length for the DQO queue format in the gve driver. The goal is to make RX buffer length config more explicit, easy to change, and performant by default. We accomplish that in four patches: 1. Currently, the buffer length is implicitly coupled with the header split setting, which is an unintuitive and restrictive design. The first patch decouples the RX buffer length from the header split configuration. 2. The second patch is a preparatory step for third. It converts the XDP config verification method to use extack for better error reporting. 3. The third patch exposes the `rx_buf_len` parameter to userspace via ethtool, allowing user to directly view or modify the RX buffer length if supported by the device. 4. The final patch improves the out-of-the-box RX single stream throughput by >10% by changing the driver's default behavior to select the maximum supported RX buffer length advertised by the device during initialization. ==================== Link: https://patch.msgid.link/20251106192746.243525-1-joshwash@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-11-10gve: Default to max_rx_buffer_size for DQO if device supportedAnkit Garg
Change the driver's default behavior to prefer the largest available RX buffer length supported by the device for DQO format, rather than always using the hardcoded 2K default. Previously, the driver would initialize with `GVE_DEFAULT_RX_BUFFER_SIZE` (2K), even if the device advertised support for a larger length (e.g., 4K). Performance observations: - With LRO disabled, we observed >10% improvement in RX single stream throughput when MTU >=2048. - With LRO enabled, we observed >10% improvement in RX single stream throughput when MTU >=1460. - No regressions were observed.

2025-11-10gve: Allow ethtool to configure rx_buf_lenAnkit Garg
Add support for getting and setting the RX buffer length via the ethtool ring parameters (`ethtool -g`/`-G`). The driver restricts the allowed buffer length to 2048 (SZ_2K) by default and allows 4096 (SZ_4K) based on device options. As XDP is only supported when the `rx_buf_len` is 2048, the driver now enforces this in two places: 1. In `gve_xdp_set`, rejecting XDP programs if the current buffer length is not 2048. 2. In `gve_set_rx_buf_len_config`, rejecting buffer length changes if XDP is loaded and the new length is not 2048.

Previously, enabling header split via `gve_set_hsplit_config` also implicitly changed the RX buffer length to 4K (if supported by the device). This coupled two settings that should be orthogonal; this patch removes that side effect. After this change, `gve_set_hsplit_config` only toggles the header split configuration. The RX buffer length is no longer affected and must be configured independently.
