Description Niels de Vos 2016-03-08 04:31:21 UTC

Description of problem:
GlusterFS 3.7 and earlier do not have support for the (new) SEEK FOP. There is no check in glfs_lseek() for unknown SEEK_* operations, this needs to be added

Version-Release number of selected component (if applicable):
3.7 and before

How reproducible:
100%

Steps to Reproduce:
1. call glfs_lseek(..., ..., SEEK_DATA)

Actual results:
No error is returned.

Expected results:
-1 should get returned, and errno should have been set to EINVAL.

    gfapi: return EINVAL for unsupported  lseek() operations
    
    GlusterFS 3.8 contains support for SEEK_DATA/SEEK_HOLE. This protocol
    extension is not available in 3.7. libgfapi needs to handle unsupported
    SEEK_* operations correctly, by returning -1 and setting errno to
    EINVAL.
    
    This change is different from the patch in the master branch, it is only
    needed to do the improved error checking in this version.

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.7.9, please open a new bug report.

glusterfs-3.7.9 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
