    In the Linux kernel, the following vulnerability has been resolved: f2fs: use global inline_xattr_slab instead of per-sb slab cache As Hong Yun reported in mailing list: loop7: detected capacity change from 0 to 131072 ------------[ cut here ]------------ kmem_cache of name 'f2fs_xattr_entry-7:7' already exists WARNING: CPU: 0 PID: 24426 at mm/slab_common.c:110 kmem_cache_sanity_check mm/slab_common.c:109 [inline] WARNING: CPU: 0 PID: 24426 at mm/slab_common.c:110 __kmem_cache_create_args+0xa6/0x320 mm/slab_common.c:307 CPU: 0 UID: 0 PID: 24426 Comm: syz.7.1370 Not tainted 6.17.0-rc4 #1 PREEMPT(full) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 RIP: 0010:kmem_cache_sanity_check mm/slab_common.c:109 [inline] RIP: 0010:__kmem_cache_create_args+0xa6/0x320 mm/slab_common.c:307 Call Trace:  __kmem_cache_create include/linux/slab.h:353 [inline]  f2fs_kmem_cache_create fs/f2fs/f2fs.h:2943 [inline]  f2fs_init_xattr_caches+0xa5/0xe0 fs/f2fs/xattr.c:843  f2fs_fill_super+0x1645/0x2620 fs/f2fs/super.c:4918  get_tree_bdev_flags+0x1fb/0x260 fs/super.c:1692  vfs_get_tree+0x43/0x140 fs/super.c:1815  do_new_mount+0x201/0x550 fs/namespace.c:3808  do_mount fs/namespace.c:4136 [inline]  __do_sys_mount fs/namespace.c:4347 [inline]  __se_sys_mount+0x298/0x2f0 fs/namespace.c:4324  do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]  do_syscall_64+0x8e/0x3a0 arch/x86/entry/syscall_64.c:94  entry_SYSCALL_64_after_hwframe+0x76/0x7e The bug can be reproduced w/ below scripts: - mount /dev/vdb /mnt1 - mount /dev/vdc /mnt2 - umount /mnt1 - mounnt /dev/vdb /mnt1 The reason is if we created two slab caches, named f2fs_xattr_entry-7:3 and f2fs_xattr_entry-7:7, and they have the same slab size. Actually, slab system will only create one slab cache core structure which has slab name of "f2fs_xattr_entry-7:3", and two slab caches share the same structure and cache address. So, if we destroy f2fs_xattr_entry-7:3 cache w/ cache address, it will decre
