vhost/scsi: fix reuse of &vq->iov[out] in response

2016-09-15T06:27:53Z

commit a77ec83a57890240c546df00ca5df1cdeedb1cc3 upstream. The address of the iovec &vq->iov[out] is not guaranteed to contain the scsi command's response iovec throughout the lifetime of the command. Rather, it is more likely to contain an iovec from an immediately following command after looping back around to vhost_get_vq_desc(). Pass along the iovec entirely instead.

vhost: replace % with & on data path

We know vring num is a power of 2, so use & to mask the high bits. Signed-off-by: Michael S. Tsirkin

vhost: relax log address alignment

2015-12-07T15:27:54Z

commit 5d9a07b0de512b77bf28d2401e5fe3351f00a240 ("vhost: relax used address alignment") fixed the alignment for the used virtual address, but not for the physical address used for logging. That's a mistake: alignment should clearly be the same for virtual and physical addresses, Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin

Pull SCSI target updates from Nicholas Bellinger: "This series contains HCH's changes to absorb configfs attribute ->show() + ->store() function pointer usage from it's original tree-wide consumers, into common configfs code. It includes usb-gadget, target w/ drivers, netconsole and ocfs2 changes to realize the improved simplicity, that now renders the original include/target/configfs_macros.h CPP magic for fabric drivers and others, unnecessary and obsolete. And with common code in place, new configfs attributes can be added easier than ever before. Note, there are further improvements in-flight from other folks for v4.5 code in configfs land, plus number of target fixes for post -rc1 code" In the meantime, a new user of the now-removed old configfs API came in through the char/misc tree in commit 7bd1d4093c2f ("stm class: Introduce an abstraction for System Trace Module devices"). This merge resolution comes from Alexander Shishkin, who updated his stm class tracing abstraction to account for the removal of the old show_attribute and store_attribute methods in commit 517982229f78 ("configfs: remove old API") from this pull. As Alexander says about that patch: "There's no need to keep an extra wrapper structure per item and the awkward show_attribute/store_attribute item ops are no longer needed. This patch converts policy code to the new api, all the while making the code quite a bit smaller and easier on the eyes. Signed-off-by: Alexander Shishkin " That patch was folded into the merge so that the tree should be fully bisectable. * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (23 commits) configfs: remove old API ocfs2/cluster: use per-attribute show and store methods ocfs2/cluster: move locking into attribute store methods netconsole: use per-attribute show and store methods target: use per-attribute show and store methods spear13xx_pcie_gadget: use per-attribute show and store methods dlm: use per-attribute show and store methods usb-gadget/f_serial: use per-attribute show and store methods usb-gadget/f_phonet: use per-attribute show and store methods usb-gadget/f_obex: use per-attribute show and store methods usb-gadget/f_uac2: use per-attribute show and store methods usb-gadget/f_uac1: use per-attribute show and store methods usb-gadget/f_mass_storage: use per-attribute show and store methods usb-gadget/f_sourcesink: use per-attribute show and store methods usb-gadget/f_printer: use per-attribute show and store methods usb-gadget/f_midi: use per-attribute show and store methods usb-gadget/f_loopback: use per-attribute show and store methods usb-gadget/ether: use per-attribute show and store methods usb-gadget/f_acm: use per-attribute show and store methods usb-gadget/f_hid: use per-attribute show and store methods ...

vhost: fix performance on LE hosts

2015-10-28T03:17:03Z

commit 2751c9882b947292fcfb084c4f604e01724af804 ("vhost: cross-endian support for legacy devices") introduced a minor regression: even with cross-endian disabled, and even on LE host, vhost_is_little_endian is checking is_le flag so there's always a branch. To fix, simply check virtio_legacy_is_little_endian first. Cc: Greg Kurz Signed-off-by: Michael S. Tsirkin Reviewed-by: Greg Kurz Signed-off-by: David S. Miller

target: use per-attribute show and store methods

This also allows to remove the target-specific old configfs macros, and gets rid of the target_core_fabric_configfs.h header which only had one function declaration left that could be moved to a better place.

char: make misc_deregister a void function

2015-08-05T17:35:49Z

With well over 200+ users of this api, there are a mere 12 users that actually checked the return value of this function. And all of them really didn't do anything with that information as the system or module was shutting down no matter what. So stop pretending like it matters, and just return void from misc_deregister(). If something goes wrong in the call, you will get a WARNING splat in the syslog so you know how to fix up your driver. Other than that, there's nothing that can go wrong. Cc: Alasdair Kergon Cc: Neil Brown Cc: Oleg Drokin Cc: Andreas Dilger Cc: "Michael S.
