PR/42175 CVS commit: src/sys/netsmb

The following reply was made to PR kern/42175; it has been noted by GNATS.

From: Matthias Scheler <>
Subject: PR/42175 CVS commit: src/sys/netsmb
Date: Sun, 18 Oct 2009 22:53:36 +0000

 Module Name:   src
 Committed By:  tron
 Date:          Sun Oct 18 22:53:36 UTC 2009
 Modified Files:
        src/sys/netsmb: smb_smb.c
 Log Message:
 Fix detection of SMB capabilities according to the CIFS spec:
 1.) SMB_CAP_LARGE_FILES advertises support for 64-bit file offsets.
 2.) SMB_CAP_LARGE_READX and SMB_CAP_LARGE_WRITEX advertise support for
     large reads and writes (larger than 64KB).
 The code previously only used SMB_CAP_LARGE_READX and SMB_CAP_LARGE_WRITEX
 which is not correct and doesn't work for the Apple Time Capsule which
 only supports SMB_CAP_LARGE_FILES. With these changes SMBFS can copy a
 5GB to a Time Capsule and read it back without problems.
 Thanks a lot to Allen Briggs for pointing out the broke assumptions
 and explaining the CIFS spec to me. This fixes PR kern/42175.
