- Summary
- netfs: Delete subtree of 'fs/netfs' when netfs module exits
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfs: Delete subtree of 'fs/netfs' when netfs module exits
In netfs_init() or fscache_proc_init(), we create dentry under 'fs/netfs', but in netfs_exit(), we only delete the proc entry of 'fs/netfs' without deleting its subtree. This triggers the following WARNING:
================================================================== remove_proc_entry: removing non-empty directory 'fs/netfs', leaking at least 'requests' WARNING: CPU: 4 PID: 566 at fs/proc/generic.c:717 remove_proc_entry+0x160/0x1c0 Modules linked in: netfs(-) CPU: 4 UID: 0 PID: 566 Comm: rmmod Not tainted 6.11.0-rc3 #860 RIP: 0010:remove_proc_entry+0x160/0x1c0 Call Trace: netfs_exit+0x12/0x620 [netfs] __do_sys_delete_module.isra.0+0x14c/0x2e0 do_syscall_64+0x4b/0x110 entry_SYSCALL_64_after_hwframe+0x76/0x7e
Therefore use remove_proc_subtree() instead of remove_proc_entry() to fix the above problem.
