The 32-bit rfc1002 header field consists of a type byte and then a
|
|
24-bit length field, but get_rfc1002_length doesn't mask off the top
|
|
byte.
|
|
|
|
In most cases, it's not a problem since the RFC1002_SESSION_MESSAGE type
|
|
is '\0', but when doing a RFC1002 session establishment, the type is
|
|
non-zero and that throws off the returned length in smb_send_rqst.
