[PATCH v2 0/4] arm64: dts: marvell: cn913x-solidrun: fix sata ports status

by Josua Mayer

The SolidRun CN9130 SoC based boards have a variety of functional problems, in particular - SATA ports - CN9132 CEX-7 eMMC - CN9132 Clearfog PCI-E x2 / x4 ports are not functional. The SATA issue was recently introduced via changes to the armada-cp11x.dtsi, wheras the eMMC and SPI problems were present in the board dts from the very beginning. This patch-set aims to resolve the problems after testing on Debian 13 release (Linux v6.12).

[PATCH] nvdimm: ndtest: Add check for devm_kcalloc() allocations in ndtest_probe()

by Guangshuo Li

devm_kcalloc() may fail. ndtest_probe() allocates three DMA address arrays (dcr_dma, label_dma, dimm_dma) and later unconditionally uses them in ndtest_nvdimm_init(), which can lead to a NULL pointer dereference on allocation failure. Add NULL checks for all three allocations and return -ENOMEM if any allocation fails.

[PATCH v2 0/3] ext4: Add support for mounted updates to the superblock via an ioctl

by Theodore Ts'o via B4 Relay

This patch series enables a future version of tune2fs to be able to modify certain parts of the ext4 superblock without to write to the block device. The first patch fixes a potential buffer overrun caused by a maliciously moified superblock. The second patch adds support for 32-bit uid and gid's which can have access to the reserved blocks pool. The last patch adds the ioctl's which will be used by tune2fs.

Backport request for commit 5326ab737a47 ("virtio_console: fix order of fields cols and rows")

by Filip Hejsek

Hi, I would like to request backporting 5326ab737a47 ("virtio_console: fix order of fields cols and rows") to all LTS kernels. I'm working on QEMU patches that add virtio console size support. Without the fix, rows and columns will be swapped. As far as I know, there are no device implementations that use the wrong order and would by broken by the fix. Note: A previous version [1] of the patch contained "Cc: stable" and "Fixes:" tags, but they seem to have been accidentally left out from the final version. [1]: https://lore.kernel.org/all/20250320172654.624657-1-maxbr@linux.ibm.com/ Thanks, Filip Hejsek

[PATCH] usb: xhci: Check kcalloc_node() when allocating interrupter array in xhci_mem_init()

by Guangshuo Li

kcalloc_node() may fail. When the interrupter array allocation returns NULL, subsequent code uses xhci->interrupters (e.g. in xhci_add_interrupter() and in cleanup paths), leading to a potential NULL pointer dereference. Check the allocation and bail out to the existing fail path to avoid the NULL dereference.
