[PATCH openEuler-22.03-LTS-SP1] mm: avoid overflows in dirty throttling logic
by Wupeng Ma 20 Aug '24

20 Aug '24

From: Jan Kara <jack(a)suse.cz> stable inclusion from stable-v5.10.222 commit 7a49389771ae7666f4dc3426e2a4594bf23ae290 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGZUU CVE: CVE-2024-42131 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 385d838df280eba6c8680f9777bfa0d0bfe7e8b2 upstream. The dirty throttling logic is interspersed with assumptions that dirty limits in PAGE_SIZE units fit into 32-bit (so that various multiplications fit into 64-bits). If limits end up being larger, we will hit overflows, possible divisions by 0 etc. Fix these problems by never allowing so large dirty limits as they have dubious practical value anyway. For dirty_bytes / dirty_background_bytes interfaces we can just refuse to set so large limits. For dirty_ratio / dirty_background_ratio it isn't so simple as the dirty limit is computed from the amount of available memory which can change due to memory hotplug etc. So when converting dirty limits from ratios to numbers of pages, we just don't allow the result to exceed UINT_MAX. This is root-only triggerable problem which occurs when the operator sets dirty limits to >16 TB.
