2026-06-13apparmor: grab ns lock and refresh when looking up changehat child profilesRyan Lee
There was a race condition involving change_hat and profile replacement in which replacement of the parent profile during a changehat operation could result in the list of children becoming empty and the changehat operation failing. To prevent this: - grab the namespace lock until we've built the hat transition, and - use aa_get_newest_profile to avoid using stale profile objects.

2026-06-13apparmor: propagate -ENOMEM correctly in unpack_tableMaxime Bélair
Currently, if the `kvzalloc` in `unpack_table` fails, it returns NULL. This is masked by `aa_dfa_unpack` which interprets NULL as a -EPROTO, leading to confusing error messages in `apparmor_parser` [1]. The fixed behavior correctly propagates -ENOMEM on allocation failure.

2026-06-13apparmor: aa_label_alloc use aa_label_free on alloc failureZygmunt Krynicki
aa_label_alloc() allocates a secid before allocating or taking the label proxy. If the later proxy step fails, the error path only freed the label memory, leaking any resources initialized by aa_label_init(). Use aa_label_free() on the failure path so partially initialized labels release their secid and other label resources before the backing memory is freed.

aa_change_profile() builds a replacement label with fn_label_build_in_scope() before the no_new_privs subset check. The build helper can fail and return NULL or an ERR_PTR, but the result was passed to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL() check.

Instead of having two distinct paths inside the dpaa2_switch_port_set_fdb() for linking=true and linking=false, unify them. This will hopefully help in making this function easier to read.

Add a tdc test that exercises the act_ife decode path with a malformed IFE packet whose encapsulated inner Ethernet header is truncated. The injected frame has a valid outer Ethernet header (ethertype 0xED3E) and a minimal IFE header (metalen 2, i.e. no metadata TLVs), but the payload that should hold the original frame is a single byte instead of a full Ethernet header. Once ife_decode() strips the outer header and the IFE metadata, fewer than ETH_HLEN bytes are left, which previously let eth_type_trans() read past the end of the linear data.

2026-06-13net: ife: require ETH_HLEN to be pullable in ife_decode()Yong Wang
ife decode may return after making only the outer IFE header and metadata pullable. The caller then passes the decapsulated packet to eth_type_trans(), which expects the inner Ethernet header to be accessible from the linear data area. With a malformed IFE frame, the inner Ethernet header may still be shorter than ETH_HLEN in the linear area, which can lead to a crash in the original code. Fix this by extending the pull check in ife_decode() so that the inner Ethernet header is also guaranteed to be pullable before returning.

[Why] In e1000_set_eeprom(), the eeprom_buff is allocated to hold a range of words. However, only the boundary words (the first and the last) are populated from the EEPROM if the write request is not word-aligned. The words in the middle of the buffer remain uninitialized because they are intended to be completely overwritten by the new data via memcpy(). The previous implementation had a loop that performed le16_to_cpus() on the entire buffer. This resulted in endianness conversion being performed on uninitialized memory for all interior words.

2026-06-13e1000e: Use __napi_schedule_irqoff()Matt Vollrath
The __napi_schedule_irqoff() macro is intended to bypass saving and restoring IRQ state when scheduling is requested from an IRQ handler, where hard interrupts are already disabled. Use this macro in all three interrupt handlers. This was tested on a system with an I218-V and MSI interrupts. Because this is an optimization, I was interested in measuring the impact, so I added ktime_get() time measurement to e1000_intr_msi and a print of the last sample in the watchdog task. For each test case I ran a bi-directional iperf3 to saturate the line. With some help from awk, here are the statistics. 49 samples each, all units ns previous: min 678 max 1265 mean 879.429 median 806 stddev 137.188 noirq: min 707 max 1165 mean 811.857 median 790 stddev 89.486 According to this informal comparison, the mean time to handle an interrupt from start to finish is improved by about 8% under load.

2026-06-13idpf: Replace use of system_unbound_wq with system_dfl_wqMarco Crivellari
This patch continues the effort to refactor workqueue APIs, which has begun with the changes introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The point of the refactoring is to eventually alter the default behavior of workqueues to become unbound by default so that their workload placement is optimized by the scheduler. Before that to happen, workqueue users must be converted to the better named new workqueues with no intended behaviour changes: system_wq -> system_percpu_wq system_unbound_wq -> system_dfl_wq This way the old obsolete workqueues (system_wq, system_unbound_wq) can be removed in the future.

2026-06-13Merge branch 'octeontx2-af-npc-enhancements'Jakub Kicinski
Ratheesh Kannoth says: ==================== octeontx2-af: npc: Enhancements. This series extends Marvell octeontx2-af support for CN20K NPC (MCAM debuggability, allocation policy, default-rule lifetime, optional KPU profiles from firmware files, X2/X4 MCAM keyword handling in flows and defaults, and dynamic CN20K NPC private state), adds a devlink mechanism for multi-value parameters, and moves devlink_nl_param_fill() temporaries to the heap so stack usage stays reasonable once union devlink_param_value grows (patch 3). Patch 1 enforces a single RVU admin-function PCI device in the kernel. On Octeon series SoCs, hardware resources such as NPC, NIX and related blocks are global and coordinated by the AF driver; PFs and VFs request them through AF mailbox messages. Firmware exposes only one AF PCI function at boot, so two AF driver instances cannot both own that state. rvu_probe() rejects a second bind with -EBUSY, logs a warning, clears the probe gate on early allocation failures, and aligns the driver model with hardware so reviewers and automation can rely on exactly one bound AF. Patch 2 improves CN20K MCAM visibility in debugfs: mcam_layout marks enabled entries, dstats reports per-entry hit deltas (baseline updated in software after each read; hardware counters are not cleared), and mismatch lists enabled entries without a PF mapping. Patch 3 allocates the per-configuration-mode union devlink_param_value buffers and struct devlink_param_gset_ctx used by devlink_nl_param_fill() with kcalloc()/kzalloc_obj() and funnels failures through a single cleanup path so the netlink reply path stays safe as the union grows. Patch 4 (Saeed) introduces DEVLINK_PARAM_TYPE_U64_ARRAY and nested DEVLINK_ATTR_PARAM_VALUE_DATA attributes so drivers and user space can exchange bounded u64 arrays; YAML, uapi, and netlink validation are updated. Patch 5 adds a runtime devlink parameter srch_order to reorder CN20K subbank search during MCAM allocation (the param uses the u64 array type from patch 4). Patch 6 ties default MCAM entries to NIX LF alloc/free on CN20K, adds NIX_LF_DONT_FREE_DFT_IDXS for PF teardown paths that must not drop default NPC indexes while the driver still owns state, and tightens nix_lf_alloc error propagation. Patch 7 allows loading a custom KPU profile from /lib/firmware/kpu via module parameter kpu_profile, with cam2 / ptype_mask wiring and helpers that share firmware-sourced vs filesystem-sourced profile layouts. Patch 8 makes default-rule allocation, AF flow install, and PF-side RSS, defaults, and ethtool flows respect the active CN20K MCAM keyword width (X2 vs X4), including X4 reference-index masking and -EOPNOTSUPP when a flow needs X4 keys on an X2-only profile. Patch 9 replaces file-scope npc_priv and static dstats with allocation sized from discovered bank/subbank geometry, threads npc_priv_get() through CN20K NPC paths, and allocates dstats via devm_kzalloc for the debugfs helper. Patch 1 is ordered first so later patches assume a single bound AF. Heap-backed devlink_nl_param_fill() sits immediately before the U64 array param work so incremental builds stay stack-safe as the union grows; the CN20K patches keep srch_order ahead of NIX LF coordination, optional KPU profile load from firmware files, X2/X4 handling, and the npc_priv refactor that touches the same files heavily. ==================== Link: https://patch.msgid.link/20260609040453.711932-1-rkannoth@marvell.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2026-06-13octeontx2-af: npc: cn20k: Allocate npc_priv and dstats dynamically.Ratheesh Kannoth
Replace the file-scope static npc_priv with a kcalloc'd struct filled from hardware bank/subbank geometry at init (num_banks is no longer a const compile-time constant; drop init_done and use a non-NULL npc_priv pointer for liveness). Thread npc_priv_get() / pointer access through the CN20K NPC code paths, extend teardown to kfree the root struct on failure and in npc_cn20k_deinit, and adjust MCAM section setup to use the discovered subbank count. Allocate MCAM debugfs dstats via devm_kzalloc instead of a static matrix, and use the allocated backing store consistently when computing deltas (including the counter rollover compare).

2026-06-13octeontx2: cn20k: Respect NPC MCAM X2/X4 profile in flows and DFT allocRatheesh Kannoth
Default CN20K NPC rule allocation now keys off the active MCAM keyword width: use X4 with a bank-masked reference index when the silicon uses X4 keys, and X2 with the raw index otherwise (replacing the previous always-X2 / eidx + 1 behaviour). In the AF flow-install path, flows that need more than 256 key bits query the NPC profile; if the platform is fixed to X2 entries, fail with -EOPNOTSUPP instead of requesting X4. Otherwise select X4 for the MCAM alloc. On the PF, cache and pass the profile kw_type from npc_get_pfl_info through otx2_mcam_pfl_info_get(), and use it when allocating MCAM entries for RSS/defaults and when installing ethtool flows on CN20K, including masking the reference index for X4 slot layout.

2026-06-13octeontx2-af: npc: Support for custom KPU profile from filesystemRatheesh Kannoth
Flashing updated firmware on deployed devices is cumbersome. Provide a mechanism to load a custom KPU (Key Parse Unit) profile directly from the filesystem at module load time. When the rvu_af module is loaded with the kpu_profile parameter, the specified profile is read from /lib/firmware/kpu and programmed into the KPU registers. Add npc_kpu_profile_cam2 for the extended cam format used by filesystem-loaded profiles and support ptype/ptype_mask in npc_config_kpucam when profile->from_fs is set. Usage: 1. Copy the KPU profile file to /lib/firmware/kpu. 2. Build OCTEONTX2_AF as a module. 3.

2026-06-13octeontx2: cn20k: Coordinate default rules with NIX LF lifecycleRatheesh Kannoth
Add NIX_LF_DONT_FREE_DFT_IDXS so the PF can send NIX LF free during hw reinit or teardown without the AF freeing CN20K default NPC rule indexes while the driver still owns that state (otx2_init_hw_resources and otx2_free_hw_resources). On CN20K, allocate default NPC rules from NIX LF alloc before nix_interface_init, roll back with npc_cn20k_dft_rules_free on failure, and free from NIX LF free when the new flag is not set. Tighten rvu_mbox_handler_nix_lf_alloc error handling: use a single rc, propagate qmem_alloc and other errors, and set -ENOMEM only when kcalloc fails (remove the blanket -ENOMEM at the free_mem path).
