In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]smb: Log an error when close_all_cached_dirs fails[EOL][EOL]Under low-memory conditions, close_all_cached_dirs() can't move the[EOL]dentries to a separate list to dput() them once the locks are dropped.[EOL]This will result in a "Dentry still in use" error, so add an error[EOL]message that makes it clear this is what happened:[EOL][EOL][ 495.281119] CIFS: VFS: \\otters.example.com\\share Out of memory while dropping dentries[EOL][ 495.281595] ------------[ cut here ]------------[EOL][ 495.281887] BUG: Dentry ffff888115531138{i=78,n=/} still in use (2) [unmount of cifs cifs][EOL][ 495.282391] WARNING: CPU: 1 PID: 2329 at fs/dcache.c:1536 umount_check+0xc8/0xf0[EOL][EOL]Also, bail out of looping through all tcons as soon as a single[EOL]allocation fails, since we're already in trouble, and kmalloc() attempts[EOL]for subseqeuent tcons are likely to fail just like the first one did.
