2025-07-22Octeontx2-af: Add programmed macaddr to RVU pfvfHariprasad Kelam
Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters can be installed on the interface through ethtool. When a user installs a DMAC filter, the interface's MAC address is implicitly added to the filter list. To ensure consistency, this MAC address must be kept in sync with the pfvf->mac_addr field, which is used to install MAC-based NPC rules. This patch updates the pfvf->mac_addr field with the programmed MAC address and also enables VF interfaces to install DMAC filters.

2025-07-22ibmveth: Add multi buffers rx replenishment hcall supportMingming Cao
This patch enables batched RX buffer replenishment in ibmveth by using the new firmware-supported h_add_logical_lan_buffers() hcall to submit up to 8 RX buffers in a single call, instead of repeatedly calling the single-buffer h_add_logical_lan_buffer() hcall. During the probe, with the patch, the driver queries ILLAN attributes to detect IBMVETH_ILLAN_RX_MULTI_BUFF_SUPPORT bit. If the attribute is present, rx_buffers_per_hcall is set to 8, enabling batched replenishment. Otherwise, it defaults to 1, preserving the original upstream behavior with no change in code flow for unsupported systems. The core rx replenish logic remains the same. But when batching is enabled, the driver aggregates up to 8 fully prepared descriptors into a single h_add_logical_lan_buffers() hypercall. If any allocation or DMA mapping fails while preparing a batch, only the successfully prepared buffers are submitted, and the remaining are deferred for the next replenish cycle. If at runtime the firmware stops accepting the batched hcall—e,g, after a Live Partition Migration (LPM) to a host that does not support h_add_logical_lan_buffers(), the hypercall returns H_FUNCTION. In that case, the driver transparently disables batching, resets rx_buffers_per_hcall to 1, and falls back to the single-buffer hcall in next future replenishments to take care of these and future buffers. Test were done on systems with firmware that both supports and does not support the new h_add_logical_lan_buffers hcall. On supported firmware, this reduces hypercall overhead significantly over multiple buffers. SAR measurements showed about a 15% improvement in packet processing rate under moderate RX load, with heavier traffic seeing gains more than 30% Signed-off-by: Mingming Cao <mmc@linux.ibm.com> Reviewed-by: Brian King <bjking1@linux.ibm.com> Reviewed-by: Haren Myneni <haren@linux.ibm.com> Reviewed-by: Dave Marquardt <davemarq@linux.ibm.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20250719091356.57252-1-mmc@linux.ibm.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-07-22genirq: Prevent migration live lock in handle_edge_irq()Thomas Gleixner
Yicon reported and Liangyan debugged a live lock in handle_edge_irq() related to interrupt migration. If the interrupt affinity is moved to a new target CPU and the interrupt is currently handled on the previous target CPU for edge type interrupts the handler might get stuck on the previous target: CPU 0 (previous target) CPU 1 (new target) handle_edge_irq() repeat: handle_event() handle_edge_irq() if (INPROGESS) { set(PENDING); mask(); return; } if (PENDING) { clear(PENDING); unmask(); goto repeat; } The migration in software never completes and CPU0 continues to handle the pending events forever. This happens when the device raises interrupts with a high rate and always before handle_event() completes and before the CPU0 handler can clear INPROGRESS so that CPU1 sets the PENDING flag over and over. This has been observed in virtual machines. Prevent this by checking whether the CPU which observes the INPROGRESS flag is the new affinity target. If that's the case, do not set the PENDING flag and wait for the INPROGRESS flag to be cleared instead, so that the new interrupt is handled on the new target CPU and the previous CPU is released from the action. This is restricted to the edge type handler and only utilized on systems, which use single CPU targets for interrupt affinity.

2025-07-22timekeeping: Zero initialize system_counterval when querying time from phc ↵Markus Blöchl
drivers Most drivers only populate the fields cycles and cs_id of system_counterval in their get_time_fn() callback for get_device_system_crosststamp(), unless they explicitly provide nanosecond values. When the use_nsecs field was added to struct system_counterval, most drivers did not care. Clock sources other than CSID_GENERIC could then get converted in convert_base_to_cs() based on an uninitialized use_nsecs field, which usually results in -EINVAL during the following range check. Pass in a fully zero initialized system_counterval_t to cure that.

2025-07-22wifi: mac80211: fix unassigned variable accessAntonio Quartulli
In ieee80211_latest_active_link_conn_timeout() we loop over all sta->links in order to compute the timeout expiring last across all links. Such timeout is stored in `latest_timeout` which is used in the time_after() comparison before having been initialized. Fix this behaviour by initializing the variable to `jiffies` and adapt surrouding conditions accordingly. Note that the caller assumed latest_timeout to be 0 if no active link was found. This is not appropriate because jiffies=0 is a valid (and recurrent, although not often) point in time. By using `jiffies` as default value for latest_timeout, we can fix the caller as well.
