## Description

In the Linux kernel, the following vulnerability has been resolved:  mm: filemap: fix nr_pages calculation overflow in filemap_map_pages()  When running stress-ng on my Arm64 machine with v7.0-rc3 kernel, I encountered some very strange crash issues showing up as "Bad page state":  " [  734.496287] BUG: Bad page state in process stress-ng-env  pfn:415735fb [  734.496427] page: refcount:0 mapcount:1 mapping:0000000000000000 index:0x4cf316 pfn:0x415735fb [  734.496434] flags: 0x57fffe000000800(owner_2|node=1|zone=2|lastcpupid=0x3ffff) [  734.496439] raw: 057fffe000000800 0000000000000000 dead000000000122 0000000000000000 [  734.496440] raw: 00000000004cf316 0000000000000000 0000000000000000 0000000000000000 [  734.496442] page dumped because: nonzero mapcount "  After analyzing this page’s state, it is hard to understand why the mapcount is not 0 while the refcount is 0, since this page is not where the issue first occurred.  By enabling the CONFIG_DEBUG_VM config, I can reproduce the crash as well and captured the first warning where the issue appears:  " [  734.469226] page: refcount:33 mapcount:0 mapping:00000000bef2d187 index:0x81a0 pfn:0x415735c0 [  734.469304] head: order:5 mapcount:0 entire_mapcount:0 nr_pages_mapped:0 pincount:0 [  734.469315] memcg:ffff000807a8ec00 [  734.469320] aops:ext4_da_aops ino:100b6f dentry name(?):"stress-ng-mmaptorture-9397-0-2736200540" [  734.469335] flags: 0x57fffe400000069(locked|uptodate|lru|head|node=1|zone=2|lastcpupid=0x3ffff) ......

By adding more debug information, I found that 'nr_pages' had overflowed in filemap_map_pages(), causing set_pte_range() to establish mappings for a range exceeding the folio size, potentially corrupting fields of pages that do not belong to this folio (e.g., page->_mapcount).  After above analysis, I think the possible race is as follows:  CPU 0                                                  CPU 1 filemap_map_pages()                                   ext4_setattr()    //get and lock folio with old inode->i_size    next_uptodate_folio()                                                            .......                                                           //shrink the inode->i_size                                                           i_size_write(inode, attr->ia_size);     //calculate the end_pgoff with the new inode->i_size    file_end = DIV_ROUND_UP(i_size_read(mapping->host), PAGE_SIZE) - 1;    end_pgoff = min(end_pgoff, file_end);     ......    //nr_pages can be overflowed, cause xas.xa_index > end_pgoff    end = folio_next_index(folio) - 1;    nr_pages = min(end, end_pgoff) - xas.xa_index + 1;     ......    //map large folio    filemap_map_folio_range()                                                           ......                                                           //truncate folios                                                           truncate_pagecache(inode, inode->i_size);  To fix this issue, move the 'end_pgoff' calculation before next_uptodate_folio(), so the retrieved folio stays consistent with the file end to avoid  ---truncated---
