[merged mm-hotfixes-stable] nilfs2-fix-possible-int-overflows-in-nilfs_fiemap.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: nilfs2: fix possible int overflows in nilfs_fiemap() has been removed from the -mm tree. Its filename was nilfs2-fix-possible-int-overflows-in-nilfs_fiemap.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Nikita Zhandarovich <n.zhandarovich(a)fintech.ru> Subject: nilfs2: fix possible int overflows in nilfs_fiemap() Date: Sat, 25 Jan 2025 07:20:53 +0900 Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result by being prepared to go through potentially maxblocks == INT_MAX blocks, the value in n may experience an overflow caused by left shift of blkbits. While it is extremely unlikely to occur, play it safe and cast right hand expression to wider type to mitigate the issue.

[merged mm-hotfixes-stable] mm-kmemleak-fix-upper-boundary-check-for-physical-address-objects.patch removed from -mm tree

The quilt patch titled Subject: mm: kmemleak: fix upper boundary check for physical address objects has been removed from the -mm tree. Its filename was mm-kmemleak-fix-upper-boundary-check-for-physical-address-objects.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Catalin Marinas <catalin.marinas(a)arm.com> Subject: mm: kmemleak: fix upper boundary check for physical address objects Date: Mon, 27 Jan 2025 18:42:33 +0000 Memblock allocations are registered by kmemleak separately, based on their physical address. During the scanning stage, it checks whether an object is within the min_low_pfn and max_low_pfn boundaries and ignores it otherwise. With the recent addition of __percpu pointer leak detection (commit 6c99d4eb7c5e ("kmemleak: enable tracking for percpu pointers")), kmemleak started reporting leaks in setup_zone_pageset() and setup_per_cpu_pageset(). These were caused by the node_data[0] object (initialised in alloc_node_data()) ending on the PFN_PHYS(max_low_pfn) boundary. The non-strict upper boundary check introduced by commit 84c326299191 ("mm: kmemleak: check physical address when scan") causes the pg_data_t object to be ignored (not scanned) and the __percpu pointers it contains to be reported as leaks. Make the max_low_pfn upper boundary check strict when deciding whether to ignore a physical address object and not scan it.

[PATCH] USB: pci-quirks: Fix HCCPARAMS register error for LS7A EHCI

LS7A EHCI controller doesn't have extended capabilities, so the EECP (EHCI Extended Capabilities Pointer) field of HCCPARAMS register should be 0x0, but it reads as 0xa0 now. This is a hardware flaw and will be fixed in future, now just clear the EECP field to avoid error messages on boot: ......
