Here is the macro https://github.com/HeisSpiter/hepunion/blob/master/fs/hepunion/hepunion.h#L393
Now this driver is at 2.6.18 kernel. I have to upgrade it to 3.8.3. As I have said "current" in kernel is a global macro, that always point to the "struct task_struct * " of the currently executing task (for details on task_struct, ref Robert Love, pg 24-27). https://github.com/HeisSpiter/hepunion/blob/master/fs/hepunion/hepunion.h#L397 Now if you look at thse two lines- current->fsuid = 0; \ current->fsgid = 0 Now task struct does not contain fsuid and fsgid, instead you have struct cred containing fsuid and fsgid. http://lxr.free-electrons.com/source/include/linux/cred.h#L102 So normal method is struct cred *new1; new1 =prepare_creds(); //make changes to any member of this structure commit_creds(new1); Now this above action I need to perform through a macro, in order to bring minimal changes to the driver. Now, I have told everything. Can someone suggest something that might work.
