Hi,
I'm having a problem with a simple sanity check performed by 'iozone -a'.
Basically, iozone create a file with a permission value of 0 and then it tries
to truncate it:
1) fd = open("file", O_WRONLY|O_CREAT, 0)
2) ftruncate(fd, 0)
In zfs-fuse, the ftruncate() call ends up calling zfs_setattr() with AT_SIZE
set in the attribute mask.
The problem is that one of the first things zfs_setattr() does is validate the
permissions (by calling zfs_zaccess()), which fails since the file owner
doesn't have write permission.
What am I doing wrong here? iozone seems to work in Solaris.
Thanks.
