2023-11-16macvlan: Don't propagate promisc change to lower dev in passthruVlad Buslov1-1/+1
Macvlan device in passthru mode sets its lower device promiscuous mode according to its MACVLAN_FLAG_NOPROMISC flag instead of synchronizing it to its own promiscuity setting. However, macvlan_change_rx_flags() function doesn't check the mode before propagating such changes to the lower device which can cause net_device->promiscuity counter overflow as illustrated by reproduction example [0] and resulting dmesg log [1]. Fix the issue by first verifying the mode in macvlan_change_rx_flags() function before propagating promiscuous mode change to the lower device.

2023-11-15net/mlx5e: Reduce the size of icosq_strSaeed Mahameed1-2/+2
icosq_str size is unnecessarily too long, and it causes a build warning -Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B, hence this patch reduces the size to 32B which should be more than enough to host the string: "ICOSQ: 0x%x, ". While here, add a missing space in the formatted string.

Previously, mlx5e_ptp_poll_ts_cq would update the device doorbell with the incremented consumer index after the relevant software counters in the kernel were updated. In the mlx5e_sq_xmit_wqe context, this would lead to either overrunning the device CQ or exceeding the expected software buffer size in the device CQ if the device CQ size was greater than the software buffer size. Update the relevant software counter only after updating the device CQ consumer index in the port timestamping napi_poll context.

2023-11-15net/mlx5e: Track xmit submission to PTP WQ after populating metadata mapRahul Rameshbabu1-1/+1
Ensure the skb is available in metadata mapping to skbs before tracking the metadata index for detecting undelivered CQEs. If the metadata index is put in the tracking list before putting the skb in the map, the metadata index might be used for detecting undelivered CQEs before the relevant skb is available in the map, which can lead to a null-ptr-deref.

2023-11-15net/mlx5e: fix double free of encap_header in update funcsGavin Li1-10/+10
Follow up to the previous patch to fix the same issue for mlx5e_tc_tun_update_header_ipv4{6} when mlx5_packet_reformat_alloc() fails. When mlx5_packet_reformat_alloc() fails, the encap_header allocated in mlx5e_tc_tun_update_header_ipv4{6} will be released within it. However, e->encap_header is already set to the previously freed encap_header before mlx5_packet_reformat_alloc(). As a result, the later mlx5e_encap_put() will free e->encap_header again, causing a double free issue. mlx5e_encap_put() --> mlx5e_encap_dealloc() --> kfree(e->encap_header) This patch fix it by not setting e->encap_header until mlx5_packet_reformat_alloc() success.

2023-11-15net/mlx5: Free used cpus mask when an IRQ is releasedMaher Sanalla2-48/+19
Each EQ table maintains a cpumask of the already used CPUs that are mapped to IRQs to ensure that each IRQ gets mapped to a unique CPU. However, on IRQ release, the said cpumask is not updated by clearing the CPU from the mask to allow future IRQ request, causing the following error when a SF is reloaded after it has utilized all CPUs for its IRQs: mlx5_irq_affinity_request:135:(pid 306010): Didn't find a matching IRQ. err = -28 Thus, when releasing an IRQ, clear its mapped CPU from the used CPUs mask, to prevent the case described above. While at it, move the used cpumask update to the EQ layer as it is more fitting and preserves symmetricity of the IRQ request/release API.

'attr_name_kobj' is allocated using kzalloc, but on all the error paths it is not freed, hence we have a memory leak. Fix the error path before kobject_init_and_add() by adding kfree(). kobject_put() must be always called after passing the object to kobject_init_and_add(). Only the error path which is immediately next to kobject_init_and_add() calls kobject_put() and not any other error path after it. Fix the error handling after kobject_init_and_add() by moving the kobject_put() into the goto label err_other_attr_init that is already used by all the error paths after kobject_init_and_add().

2023-11-14nouveau/gsp/r535: Fix a NULL vs error pointer bugDan Carpenter1-2/+2
The r535_gsp_cmdq_get() function returns error pointers but this code checks for NULL. Also we need to propagate the error pointer back to the callers in r535_gsp_rpc_get(). Returning NULL will lead to a NULL pointer dereference.

2023-11-14mmc: cqhci: Fix task clearing in CQE error recoveryAdrian Hunter1-16/+16
If a task completion notification (TCN) is received when there is no outstanding task, the cqhci driver issues a "spurious TCN" warning. This was observed to happen right after CQE error recovery. When an error interrupt is received the driver runs recovery logic. It halts the controller, clears all pending tasks, and then re-enables it. On some platforms, like Intel Jasper Lake, a stale task completion event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set. This results in either: a) Spurious TC completion event for an empty slot. b) Corrupted data being passed up the stack, as a result of premature completion for a newly added task. Rather than add a quirk for affected controllers, ensure tasks are cleared by toggling CQHCI_ENABLE, which would happen anyway if cqhci_clear_all_tasks() timed out. This is simpler and should be safe and effective for all controllers.
