Pull ceph fix from Sage Weil: "This fixes a regression introduced during the last merge window when mapping non-existent images." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: rbd: don't zero-fill non-image object requests
-
Alex Elder authored
A result of ENOENT from a read request for an object that's part of an rbd image indicates that there is a hole in that portion of the image. Similarly, a short read for such an object indicates that the remainder of the read should be interpreted a full read with zeros filling out the end of the request. This behavior is not correct for objects that are not backing rbd image data. Currently rbd_img_obj_request_callback() assumes it should be done for all objects. Change rbd_img_obj_request_callback() so it only does this zeroing for image objects. Encapsulate that special handling in its own function. Add an assertion that the image object request is a bio request, since we assume that (and we currently don't support any other types). This resolves a problem identified here: http://tracker.ceph.com/issues/4559 The regression was introduced by bf0d5f50.

A nice small set of worthy bits and bobs.

A user reported a panic where we were panicing somewhere in tree_backref_for_extent from scrub_print_warning. He only captured the trace but looking at scrub_print_warning we drop the path right before we mess with the extent buffer to print out a bunch of stuff, which isn't right. So fix this by dropping the path after we use the eb if we need to.

This patch fixes a regression introduced in v3.8-rc1 code where a failed target_check_reservation() check in target_setup_cmd_from_cdb() was causing an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation performed by an unregistered / unreserved iscsi initiator port. This regression is only effecting iscsi-target due to a special case check for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(), and was still correctly disallowing WRITE commands from backend submission for unregistered / unreserved initiator ports, while returning the incorrect SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT assignment. This regression was first introduced with: commit de103c93 Author: Christoph Hellwig <hch@lst.de> Date: Tue Nov 6 12:24:09 2012 -0800 target: pass sense_reason as a return value Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment during a target_check_reservation() failure, so that iscsi-target code sends the correct SCSI status. All other fabrics using target_submit_cmd_*() with a RESERVATION_CONFLICT call to transport_generic_request_failure() are not effected by this bug.

This reverts commit 18693050 ("mm: introduce VM_POPULATE flag to better deal with racy userspace programs"). VM_POPULATE only has any effect when userspace plays racy games with vmas by trying to unmap and remap memory regions that mmap or mlock are operating on. Also, the only effect of VM_POPULATE when userspace plays such games is that it avoids populating new memory regions that get remapped into the address range that was being operated on by the original mmap or mlock calls. Let's remove VM_POPULATE as there isn't any strong argument to mandate a new vm_flag.
