2025-07-18wifi: mac80211: support initialising an S1G short beaconing BSSLachlan Hodges
Introduce the ability to parse the short beacon data and long beacon period. The long beacon period represents the number of beacon intervals between each long beacon transmission. Additionally, as a BSS cannot change its configuration such that short beaconing is dynamically disabled/enabled without tearing down the interface - we ensure we have an existing short beacon before performing the update.

2025-07-18wifi: cfg80211: support configuring an S1G short beaconing BSSLachlan Hodges
S1G short beacons are an optional frame type used in an S1G BSS that contain a limited set of elements. While they are optional, they are a fundamental part of S1G that enables significant power saving. Expose 2 additional netlink attributes, NL80211_ATTR_S1G_LONG_BEACON_PERIOD which denotes the number of beacon intervals between each long beacon and NL80211_ATTR_S1G_SHORT_BEACON which is a nested attribute containing the short beacon tail and head. We split them as the long beacon period cannot be updated, and is only used when initialisng the interface, whereas the short beacon data can be used to both initialise and update the templates. This follows how things such as the beacon interval and DTIM period currently operate. During the initialisation path, we ensure we have the long beacon period if the short beacon data is being passed down, whereas the update path will simply update the template if its sent down. The short beacon data is validated using the same routines for regular beacons as they support correctly parsing the short beacon format while ensuring the frame is well-formed.

2025-07-18wifi: mac80211: extend connection monitoring for MLOMaharaja Kennadyrajan
Currently, reset connection monitor (ieee80211_sta_reset_conn_monitor()) timer is handled only for non-AP non-MLD STA and do not support non-AP MLD STA. The current implementation checks for the CSA active and update the monitor timer with the timeout value of deflink and reset the timer based on the deflink's timeout value else schedule the connection loss work when the deflink is timed out and it won't work for the non-AP MLD STA. Handle the reset connection monitor timer for non-AP MLD STA by updating the monitor timer with the timeout value which is determined based on the link that will expire last among all the links in MLO. If at least one link has not timed out, the timer is updated accordingly with the latest timeout value else schedule the connection loss work when all links have timed out. Remove the MLO-related WARN_ON() checks in the beacon and connection monitoring logic code paths as they support MLO now.

2025-07-18wifi: mac80211: Add link iteration macro for link data with rcu_dereferenceMaharaja Kennadyrajan
Currently, the existing macro for_each_link_data() uses sdata_dereference() which requires the wiphy lock. This lock cannot be used in atomic or RCU read-side contexts, such as in the RX path. Introduce a new macro, for_each_link_data_rcu(), that iterates over link of sdata using rcu_dereference(), making it safe to use in RCU contexts. This allows callers to access link data without requiring the wiphy lock. The macro takes into account the vif.valid_links bitmap and ensures only valid links are accessed safely. Callers are responsible for ensuring that rcu_read_lock() is held when using this macro.

2025-07-18wifi: mac80211: fix macro scoping in for_each_link_dataAditya Kumar Singh
The for_each_link_data() macro currently declares a local variable __sdata directly, which could lead to compiler warnings or errors when reused in the same function or within switch-case blocks due to variable redefinition or invalid scoping. To address this, restructure the macro to use an outer for-loop that runs only once, allowing safe declaration of __sdata without polluting the outer scope. This ensures compatibility with static analyzers. No functional changes; this is purely a cleanup to improve macro hygiene.

That's fine for what the code does now, but with the removal of __counted_by() in 444020f4bf06 ("wifi: cfg80211: remove scan request n_channels counted_by") it's no longer needed and it does leave a bit of a landmine there since breaking out of some code to send the scan or something would leave it wrong. Remove the now superfluous n_channels settings.

2025-07-18efivarfs: Fix memory leak of efivarfs_fs_info in fs_context error pathsBreno Leitao
When processing mount options, efivarfs allocates efivarfs_fs_info (sfi) early in fs_context initialization. However, sfi is associated with the superblock and typically freed when the superblock is destroyed. If the fs_context is released (final put) before fill_super is called—such as on error paths or during reconfiguration—the sfi structure would leak, as ownership never transfers to the superblock. Implement the .free callback in efivarfs_context_ops to ensure any allocated sfi is properly freed if the fs_context is torn down before fill_super, preventing this memory leak.

2025-07-17libbpf: Fix handling of BPF arena relocationsAndrii Nakryiko
Initial __arena global variable support implementation in libbpf contains a bug: it remembers struct bpf_map pointer for arena, which is used later on to process relocations. Recording this pointer is problematic because map pointers are not stable during ELF relocation collection phase, as an array of struct bpf_map's can be reallocated, invalidating all the pointers. Libbpf is dealing with similar issues by using a stable internal map index, though for BPF arena map specifically this approach wasn't used due to an oversight. The resulting behavior is non-deterministic issue which depends on exact layout of ELF object file, number of actual maps, etc. We didn't hit this until very recently, when this bug started triggering crash in BPF CI when validating one of sched-ext BPF programs. The fix is rather straightforward: we just follow an established pattern of remembering map index (just like obj->kconfig_map_idx, for example) instead of `struct bpf_map *`, and resolving index to a pointer at the point where map information is necessary. While at it also add debug-level message for arena-related relocation resolution information, which we already have for all other kinds of maps.

IPSec hardware offload in legacy mode should not be affected by the steering mode, hence it should also work properly with hmfs mode. Remove steering mode validation when calculating the cap for packet offload, this will also enable the missing cap MLX5_IPSEC_CAP_PRIO needed for crypto offload.

Luo Jie says: ==================== Add shared PHY counter support for QCA807x and QCA808x The implementation of the PHY counter is identical for both QCA808x and QCA807x series devices. This includes counters for both good and bad CRC frames in the RX and TX directions, which are active when CRC checking is enabled. This patch series introduces PHY counter functions into a shared library, enabling counter support for the QCA808x and QCA807x families through this common infrastructure. Additionally, enable CRC checking and configure automatic clearing of counters after reading within config_init() to ensure accurate counter recording. v2: https://lore.kernel.org/20250714-qcom_phy_counter-v2-0-94dde9d9769f@quicinc.com v1: https://lore.kernel.org/20250709-qcom_phy_counter-v1-0-93a54a029c46@quicinc.com ==================== Link: https://patch.msgid.link/20250715-qcom_phy_counter-v3-0-8b0e460a527b@quicinc.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Add PHY counter functionality to the shared library. The implementation is identical for the current QCA807X and QCA808X PHYs. The PHY counter can be configured to perform CRC checking for both received and transmitted packets. Additionally, the packet counter can be set to automatically clear after it is read. The PHY counter includes 32-bit packet counters for both RX (received) and TX (transmitted) packets, as well as 16-bit counters for recording CRC error packets for both RX and TX.

2025-07-17selftests: net: prevent Python from buffering the outputJakub Kicinski
Make sure Python doesn't buffer the output, otherwise for some tests we may see false positive timeouts in NIPA. NIPA thinks that a machine has hung if the test doesn't print anything for 3min. This is also nice to heave for running the tests manually, especially in vng.
