"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nceph: drop messages from MDS when unmounting\n\nWhen unmounting all the dirty buffers will be flushed and after\nthe last osd request is finished the last reference of the i_count\nwill be released. Then it will flush the dirty cap/snap to MDSs,\nand the unmounting won't wait the possible acks, which will ihold\nthe inodes when updating the metadata locally but makes no sense\nany more, of this. This will make the evict_inodes() to skip these\ninodes.\n\nIf encrypt is enabled the kernel generate a warning when removing\nthe encrypt keys when the skipped inodes still hold the keyring:\n\nWARNING: CPU: 4 PID: 168846 at fs/crypto/keyring.c:242 fscrypt_destroy_keyring+0x7e/0xd0\nCPU: 4 PID: 168846 Comm: umount Tainted: G S 6.1.0-rc5-ceph-g72ead199864c #1\nHardware name: Supermicro SYS-5018R-WR/X10SRW-F, BIOS 2.0 12/17/2015\nRIP: 0010:fscrypt_destroy_keyring+0x7e/0xd0\nRSP: 0018:ffffc9000b277e28 EFLAGS: 00010202\nRAX: 0000000000000002 RBX: ffff88810d52ac00 RCX: ffff88810b56aa00\nRDX: 0000000080000000 RSI: ffffffff822f3a09 RDI: ffff888108f59000\nRBP: ffff8881d394fb88 R08: 0000000000000028 R09: 0000000000000000\nR10: 0000000000000001 R11: 11ff4fe6834fcd91 R12: ffff8881d394fc40\nR13: ffff888108f59000 R14: ffff8881d394f800 R15: 0000000000000000\nFS: 00007fd83f6f1080(0000) GS:ffff88885fd00000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007f918d417000 CR3: 000000017f89a005 CR4: 00000000003706e0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n<TASK>\ngeneric_shutdown_super+0x47/0x120\nkill_anon_super+0x14/0x30\nceph_kill_sb+0x36/0x90 [ceph]\ndeactivate_locked_super+0x29/0x60\ncleanup_mnt+0xb8/0x140\ntask_work_run+0x67/0xb0\nexit_to_user_mode_prepare+0x23d/0x240\nsyscall_exit_to_user_mode+0x25/0x60\ndo_syscall_64+0x40/0x80\nentry_SYSCALL_64_after_hwframe+0x63/0xcd\nRIP: 0033:0x7fd83dc39e9b\n\nLater the kernel will crash when iput() the inodes and dereferencing\nthe \"sb->s_master_keys\", which has been released by the\ngeneric_shutdown_super()."
