From 233a0d97cf69d1e84029f906d043d1a880943464 Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Fri, 28 Jun 2013 11:47:33 +0200 Subject: [PATCH] cifs: fill TRANS2_QUERY_FILE_INFO ByteCount fields Currently the trans2 ByteCount field is incorrectly left zero in TRANS2_QUERY_FILE_INFO info_level=SMB_QUERY_FILE_ALL_INFO and info_level=SMB_QUERY_FILE_UNIX_BASIC requests. The field should properly reflect the FID, information_level and padding bytes carried in these requests. Leaving this field zero causes such requests to fail against Novell CIFS servers. Other SMB servers (e.g. Samba) use the parameter count fields for data length calculations instead, so do not suffer the same fate.
