Hi,
please see attached patchset to honour output buffer length set by the
client for SMB2 GetInfo requests. The patchset also enhances GetInfo for
file system information classes SMB_QUERY_FS_VOLUME_INFO and
SMB_QUERY_FS_ATTRIBUTE_INFO to return partial, but valid data in case
output buffer length is too small. This behaviour is documented in MS-FSCC.
We had a customer defect where a client submitted a GetInfo
SMB_QUERY_FS_VOLUME_INFO request with a output buffer length of 24
bytes. Samba responded with a full length response of 40 bytes which
resulted in a client error.
Regards
Ralph
