简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- ceph卸载时丢失来自 MDS 的消息在卸载时将刷新所有脏缓冲区并且在完成最后一个 osd 请求后将释放 i_count 的最后一个引用。然后其会将脏端点/快照刷新到 MDS并且不会等待可能的 ack就会执行卸载这将在本地更新元数据时保留 inode但却不再有任何意义。这将使 evict_inodes() 跳过这些 inode。如果启用了加密在跳过的 inode 仍然保留 keyring 的情况下删除加密密钥时内核会生成警告WARNING: CPU: 4 PID: 168846 at fs/crypto/keyring.c:242 fscrypt_destroy_keyring+0x7e/0xd0 CPU: 4 PID 168846 Comm: umount Tainted: GS 6.1.0-rc5-ceph-g72ead199864c #1 硬件名称: Supermicro SYS-5018R-WR/X10SRW-F, BIOS 2.0 2015 年 12 月 17 日 RIP
