The problem has been bisected to 7c877586da3 (&#34;readahead: properly shorten readahead when falling back to do_page_cache_ra()&#34;). The cause of the problem is that ra-&gt;size can be shrunk by read_pages() call and subsequently we end up calling do_page_cache_ra() with negative (read huge positive) number of pages. Let&#39;s revert 7c877586da3 for now until we can find a proper way how the logic in read_pages() and page_cache_ra_order() can coexist. This can lead to reduced readahead throughput due to readahead window confusion but that&#39;s better than outright hangs.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>Revert &#34;readahead: properly shorten readahead when falling back to do_page_cache_ra()&#34;</p> <p>This reverts commit 7c877586da3178974a8a94577b6045a48377ff25.</p> <p>Anders and Philippe have reported that recent kernels occasionally hang when used with NFS in readahead code.
