The problem has been bisected to\n7c877586da3 (\"readahead: properly shorten readahead when falling back to\ndo_page_cache_ra()\").  The cause of the problem is that ra->size can be\nshrunk by read_pages() call and subsequently we end up calling\ndo_page_cache_ra() with negative (read huge positive) number of pages. \nLet's revert 7c877586da3 for now until we can find a proper way how the\nlogic in read_pages() and page_cache_ra_order() can coexist.  This can\nlead to reduced readahead throughput due to readahead window confusion but\nthat's better than outright hangs."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/readahead.c"],"versions":[{"version":"7c877586da3178974a8a94577b6045a48377ff25","lessThan":"85351e4941a253e4c50fb7048bfc19b60b4ec44b","status":"affected","versionType":"git"},{"version":"7c877586da3178974a8a94577b6045a48377ff25","lessThan":"a220d6b95b1ae12c7626283d7609f0a1438e6437","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/readahead.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.5","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/85351e4941a253e4c50fb7048bfc19b60b4ec44b"},{"url":"https://git.kernel.org/stable/c/a220d6b95b1ae12c7626283d7609f0a1438e6437"}],"title":"Revert \"readahead: properly shorten readahead when falling back to do_page_cache_ra()\"","x_generator":{"engine":"bippy-1.2.0"}}}}
