To delay closing a handle (e.g. for caching directory contents) we should be requesting HANDLE as well as READ (as we already do for deferred close of files). See MS-SMB2 3.3.1.4 e.g. Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Steve French <stfrench@xxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- fs/smb/client/smb2ops.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/fs/smb/client/smb2ops.c +++ b/fs/smb/client/smb2ops.c @@ -4080,7 +4080,7 @@ map_oplock_to_lease(u8 oplock) if (oplock == SMB2_OPLOCK_LEVEL_EXCLUSIVE) return SMB2_LEASE_WRITE_CACHING_LE | SMB2_LEASE_READ_CACHING_LE; else if (oplock == SMB2_OPLOCK_LEVEL_II) - return SMB2_LEASE_READ_CACHING_LE; + return SMB2_LEASE_READ_CACHING_LE | SMB2_LEASE_HANDLE_CACHING_LE; else if (oplock == SMB2_OPLOCK_LEVEL_BATCH) return SMB2_LEASE_HANDLE_CACHING_LE | SMB2_LEASE_READ_CACHING_LE | SMB2_LEASE_WRITE_CACHING_LE;
