The df for a SMB2 share triggers a GetInfo call for FS_FULL_SIZE_INFORMATION. The values returned are used to populate struct statfs. The problem is that none of the information returned by the call contains the total blocks available on the filesystem. Instead we use the blocks available to the user ie. quota limitation when filling out statfs.f_blocks. The information returned does contain Actual free units on the filesystem and is used to populate statfs.f_bfree. For users with quota enabled, it can lead to situations where the total free space reported is more than the total blocks on the system ending up with df reports like the following # df -h /mnt/a Filesystem Size Used Avail Use% Mounted on //192.168.22.10/a 2.5G -2.3G 2.5G - /mnt/a To fix this problem, we instead populate both statfs.f_bfree with the same value as statfs.f_bavail ie. CallerAvailableAllocationUnits. This is similar to what is done already in the code for cifs and df now reports the quota information for the user used to mount the share. # df --si /mnt/a Filesystem Size Used Avail Use% Mounted on //192.168.22.10/a 2.7G 101M 2.6G 4% /mnt/a Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Signed-off-by: Pierguido Lambri <plambri@redhat.com> Signed-off-by: Steve French <smfrench@gmail.com> Cc: <stable@vger.kernel.org>
