2017-03-20ALSA: ctxfi: Fix the incorrect check of dma_set_mask() callTakashi Iwai1-1/+1
In the commit [15c75b09f8d1: ALSA: ctxfi: Fallback DMA mask to 32bit], I forgot to put "!" at dam_set_mask() call check in cthw20k1.c (while cthw20k2.c is OK). This patch fixes that obvious bug. (As a side note: although the original commit was completely wrong, it's still working for most of machines, as it sets to 32bit DMA mask in the end. So the bug severity is low.)

2017-03-19mm/swap: don't BUG_ON() due to uninitialized swap slot cacheLinus Torvalds1-1/+1
This BUG_ON() triggered for me once at shutdown, and I don't see a reason for the check. The code correctly checks whether the swap slot cache is usable or not, so an uninitialized swap slot cache is not actually problematic afaik. I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since I'm not sure why that seemingly pointless check was there. I suspect the real fix is to just remove it entirely, but for now we'll warn about it but not bring the machine down.

Current driver wait for FW to be in the ready state before processing in-coming commands. For Arbitrated Loop or Point-to- Point (not switch), FW Ready state can take a while. FW will transition to ready state after all Nports have been logged in. In the mean time, certain initiators have completed the login and starts IO.

If the remote port have started the login process, then the PLOGI and PRLI should be back to back. Driver will allow the remote port to complete the process.

The main lock that needs to be held for CMD or TMR submission to upper layer is the sess_lock. The sess_lock is used to serialize cmd submission and session deletion.

2017-03-18tcmu: Convert cmd_time_out into backend device attributeNicholas Bellinger1-26/+68
Instead of putting cmd_time_out under ../target/core/user_0/foo/control, which has historically been used by parameters needed for initial backend device configuration, go ahead and move cmd_time_out into a backend device attribute. In order to do this, tcmu_module_init() has been updated to create a local struct configfs_attribute **tcmu_attrs, that is based upon the existing passthrough_attrib_attrs along with the new cmd_time_out attribute. Once **tcm_attrs has been setup, go ahead and point it at tcmu_ops->tb_dev_attrib_attrs so it's picked up by target-core. Also following MNC's previous change, ->cmd_time_out is stored in milliseconds but exposed via configfs in seconds. Also, note this patch restricts the modification of ->cmd_time_out to before + after the TCMU device has been configured, but not while it has active fabric exports.

2017-03-18target: fix race during implicit transition work flushesMike Christie1-9/+1
This fixes the following races: 1. core_alua_do_transition_tg_pt could have read tg_pt_gp_alua_access_state and gone into this if chunk: if (!explicit && atomic_read(&tg_pt_gp->tg_pt_gp_alua_access_state) == ALUA_ACCESS_STATE_TRANSITION) { and then core_alua_do_transition_tg_pt_work could update the state. core_alua_do_transition_tg_pt would then only set tg_pt_gp_alua_pending_state and the tg_pt_gp_alua_access_state would not get updated with the second calls state. 2. core_alua_do_transition_tg_pt could be setting tg_pt_gp_transition_complete while the tg_pt_gp_transition_work is already completing. core_alua_do_transition_tg_pt then waits on the completion that will never be called. To handle these issues, we just call flush_work which will return when core_alua_do_transition_tg_pt_work has completed so there is no need to do the complete/wait. And, if core_alua_do_transition_tg_pt_work was running, instead of trying to sneak in the state change, we just schedule up another core_alua_do_transition_tg_pt_work call. Note that this does not handle a possible race where there are multiple threads call core_alua_do_transition_tg_pt at the same time. I think we need a mutex in target_tg_pt_gp_alua_access_state_store. Signed-off-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2017-03-18target: allow userspace to set state to transitioningMike Christie1-15/+22

2017-03-18target: fix ALUA transition timeout handlingMike Christie2-16/+9
The implicit transition time tells initiators the min time to wait before timing out a transition. We currently schedule the transition to occur in tg_pt_gp_implicit_trans_secs seconds so there is no room for delays. If core_alua_do_transition_tg_pt_work->core_alua_update_tpg_primary_metadata needs to write out info to a remote file, then the initiator can easily time out the operation.

2017-03-18target: Use system workqueue for ALUA transitionsMike Christie1-5/+3
If tcmu-runner is processing a STPG and needs to change the kernel's ALUA state then we cannot use the same work queue for task management requests and ALUA transitions, because we could deadlock. The problem occurs when a STPG times out before tcmu-runner is able to call into target_tg_pt_gp_alua_access_state_store-> core_alua_do_port_transition -> core_alua_do_transition_tg_pt -> queue_work. In this case, the tmr is on the work queue waiting for the STPG to complete, but the STPG transition is now queued behind the waiting tmr. Note: This bug will also be fixed by this patch: http://www.spinics.net/lists/target-devel/msg14560.html which switches the tmr code to use the system workqueues. For both, I am not sure if we need a dedicated workqueue since it is not a performance path and I do not think we need WQ_MEM_RECLAIM to make forward progress to free up memory like the block layer does.

This patch allows passthrough backends to use the core/base LIO ALUA setup and state checks, but still handle the execution of commands. This will allow the target_core_user module to execute STPG and RTPG in userspace, and not have to duplicate the ALUA state checks, path information (needed so we can check if command is executable on specific paths) and setup (rtslib sets/updates the configfs ALUA interface like it does for iblock or file). For STPG, the target_core_user userspace daemon, tcmu-runner will still execute the STPG, and to update the core/base LIO state it will use the existing configfs interface. For RTPG, tcmu-runner will loop over configfs and/or cache the state. Signed-off-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2017-03-17pNFS/flexfiles: never nfs4_mark_deviceid_unavailableWeston Andros Adamson4-10/+31
The flexfiles layout should never mark a device unavailable. Move nfs4_mark_deviceid_unavailable out of nfs4_pnfs_ds_connect and call directly from files layout where it's still needed. The flexfiles driver still handles marked devices in error paths, but will now print a rate limited warning.

2017-03-17pNFS: return status from nfs4_pnfs_ds_connectWeston Andros Adamson6-6/+48
The nfs4_pnfs_ds_connect path can call rpc_create which can fail or it can wait on another context to reach the same failure. This checks that the rpc_create succeeded and returns the error to the caller. When an error is returned, both the files and flexfiles layouts will return NULL from _prepare_ds(). The flexfiles layout will also return the layout with the error NFS4ERR_NXIO. Signed-off-by: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
