Description

In the Linux kernel, the following vulnerability has been resolved:

ipvs: fix WARNING in __ip_vs_cleanup_batch()

During the initialization of ip_vs_conn_net_init(), if file ip_vs_conn or ip_vs_conn_sync fails to be created, the initialization is successful by default. Therefore, the ip_vs_conn or ip_vs_conn_sync file doesn't be found during the remove.

The following is the stack information: name 'ip_vs_conn_sync' WARNING: CPU: 3 PID: 9 at fs/proc/generic.c:712 remove_proc_entry+0x389/0x460 Modules linked in: Workqueue: netns cleanup_net RIP: 0010:remove_proc_entry+0x389/0x460 Call Trace: <TASK> __ip_vs_cleanup_batch+0x7d/0x120 ops_exit_list+0x125/0x170 cleanup_net+0x4ea/0xb00 process_one_work+0x9bf/0x1710 worker_thread+0x665/0x1080 kthread+0x2e4/0x3a0 ret_from_fork+0x1f/0x30 </TASK>
