However with a sufficiently large request, the splitting logic causes each sg to be split into two commands in the DMA table, leading to overflow of the DMA table, triggering the BUG_ON(). With default settings the bug doesn't trigger, because the request size is limited by max_sectors_kb == 1280, however max_sectors_kb can be increased, and apparently some distros do that by default using udev rules. Fix the bug for 4KB kernels by reverting to the old max_segment_size. For 64KB kernels the sg_tablesize needs to be halved, to allow for the possibility that each sg will be split into two.

2024-08-20net: dsa: microchip: fix PTP config failure when using multiple portsMartin Whitaker
When performing the port_hwtstamp_set operation, ptp_schedule_worker() will be called if hardware timestamoing is enabled on any of the ports. When using multiple ports for PTP, port_hwtstamp_set is executed for each port. When called for the first time ptp_schedule_worker() returns 0. On subsequent calls it returns 1, indicating the worker is already scheduled. Currently the ksz driver treats 1 as an error and fails to complete the port_hwtstamp_set operation, thus leaving the timestamping configuration for those ports unchanged. This patch fixes this by ignoring the ptp_schedule_worker() return value.

2024-08-20igb: cope with large MAX_SKB_FRAGSPaolo Abeni
Sabrina reports that the igb driver does not cope well with large MAX_SKB_FRAG values: setting MAX_SKB_FRAG to 45 causes payload corruption on TX. An easy reproducer is to run ssh to connect to the machine. With MAX_SKB_FRAGS=17 it works, with MAX_SKB_FRAGS=45 it fails. This has been reported originally in https://bugzilla.redhat.com/show_bug.cgi?id=2265320 The root cause of the issue is that the driver does not take into account properly the (possibly large) shared info size when selecting the ring layout, and will try to fit two packets inside the same 4K page even when the 1st fraglist will trump over the 2nd head. Address the issue by checking if 2K buffers are insufficient.

2024-08-20dpaa2-switch: Fix error checking in dpaa2_switch_seed_bp()Dan Carpenter
The dpaa2_switch_add_bufs() function returns the number of bufs that it was able to add. It returns BUFS_PER_CMD (7) for complete success or a smaller number if there are not enough pages available. However, the error checking is looking at the total number of bufs instead of the number which were added on this iteration. Thus the error checking only works correctly for the first iteration through the loop and subsequent iterations are always counted as a success. Fix this by checking only the bufs added in the current iteration.

2024-08-20ice: fix truesize operations for PAGE_SIZE >= 8192Maciej Fijalkowski
When working on multi-buffer packet on arch that has PAGE_SIZE >= 8192, truesize is calculated and stored in xdp_buff::frame_sz per each processed Rx buffer. This means that frame_sz will contain the truesize based on last received buffer, but commit 1dc1a7e7f410 ("ice: Centrallize Rx buffer recycling") assumed this value will be constant for each buffer, which breaks the page recycling scheme and mess up the way we update the page::page_offset. To fix this, let us work on constant truesize when PAGE_SIZE >= 8192 instead of basing this on size of a packet read from Rx descriptor. This way we can simplify the code and avoid calculating truesize per each received frame and on top of that when using xdp_update_skb_shared_info(), current formula for truesize update will be valid. This means ice_rx_frame_truesize() can be removed altogether. Furthermore, first call to it within ice_clean_rx_irq() for 4k PAGE_SIZE was redundant as xdp_buff::frame_sz is initialized via xdp_init_buff() in ice_vsi_cfg_rxq(). This should have been removed at the point where xdp_buff struct started to be a member of ice_rx_ring and it was no longer a stack based variable. There are two fixes tags as my understanding is that the first one exposed us to broken truesize and page_offset handling and then second introduced broken skb_shared_info update in ice_{construct,build}_skb().

2024-08-20irqchip/gic-v4: Fix ordering between vmapp and vpe locksMarc Zyngier
The recently established lock ordering mandates that the per-VM vmapp_lock is acquired before taking the per-VPE lock. As it turns out, its_vpe_set_affinity() takes the VPE lock, and then calls into its_send_vmovp(), which itself takes the vmapp lock. Obviously, this is a lock order violation.

2024-08-20irqchip/sifive-plic: Probe plic driver early for Allwinner D1 platformAnup Patel
The latest Linux RISC-V no longer boots on the Allwinner D1 platform because the sun4i_timer driver fails to get an interrupt from PLIC due to the recent conversion of the PLIC to a platform driver. Converting the sun4i timer to a platform driver does not work either because the D1 does not have a SBI timer available so early boot hangs. See the 'Closes:' link for deeper analysis. The real fix requires enabling the SBI time extension in the platform firmware (OpenSBI) and convert sun4i_timer into platform driver. Unfortunately, the real fix involves changing multiple places and can't be achieved in a short duration and aside of that requires users to update firmware. As a work-around, retrofit PLIC probing such that the PLIC is probed early only for the Allwinner D1 platform and probed as a regular platform driver for rest of the RISC-V platforms. In the process, partially revert some of the previous changes because the PLIC device pointer is not available in all probing paths.

2024-08-20bonding: fix xfrm state handling when clearing active slaveNikolay Aleksandrov
If the active slave is cleared manually the xfrm state is not flushed. This leads to xfrm add/del imbalance and adding the same state multiple times. For example when the device cannot handle anymore states we get: [ 1169.884811] bond0: (slave eni0np1): bond_ipsec_add_sa_all: failed to add SA because it's filled with the same state after multiple active slave clearings. This change also has a few nice side effects: user-space gets a notification for the change, the old device gets its mac address and promisc/mcast adjusted properly.

When only the last resource is invalid, tpmi_sst_dev_add() is returing error even if there are other valid resources before. This function should return error when there are no valid resources. Here tpmi_sst_dev_add() is returning "ret" variable. But this "ret" variable contains the failure status of last call to sst_main(), which failed for the invalid resource. But there may be other valid resources before the last entry. To address this, do not update "ret" variable for sst_main() return status. If there are no valid resources, it is already checked for by !inst below the loop and -ENODEV is returned.

This WA is applied while initializing the media GT, but it a primary GT WA (because it modifies a register on the primary GT), so the XE_WA macro is returning false even when the WA should be applied. Fix this by using the primary GT in the macro. Note that this WA only applies to PXP and we don't yet support that in Xe, so there are no negative effects to this bug, which is why we didn't see any errors in testing. v2: use the primary GT in the macro instead of marking the WA as platform-wide (Lucas, Matt).
