2020-02-04NFSv4.0: nfs4_do_fsinfo() should not do implicit lease renewalsRobert Milkowski4-14/+11
Currently, each time nfs4_do_fsinfo() is called it will do an implicit NFS4 lease renewal, which is not compliant with the NFS4 specification. This can result in a lease being expired by an NFS server. Commit 83ca7f5ab31f ("NFS: Avoid PUTROOTFH when managing leases") introduced implicit client lease renewal in nfs4_do_fsinfo(), which can result in the NFSv4.0 lease to expire on a server side, and servers returning NFS4ERR_EXPIRED or NFS4ERR_STALE_CLIENTID. This can easily be reproduced by frequently unmounting a sub-mount, then stat'ing it to get it mounted again, which will delay or even completely prevent client from sending RENEW operations if no other NFS operations are issued. Eventually nfs server will expire client's lease and return an error on file access or next RENEW. This can also happen when a sub-mount is automatically unmounted due to inactivity (after nfs_mountpoint_expiry_timeout), then it is mounted again via stat(). This can result in a short window during which client's lease will expire on a server but not on a client. This specific case was observed on production systems. This patch removes the implicit lease renewal from nfs4_do_fsinfo().

2020-02-05nvmet: update AEN list and array at one placeDaniel Wagner1-27/+36
All async events are enqueued via nvmet_add_async_event() which updates the ctrl->async_event_cmds[] array and additionally an struct nvmet_async_event is added to the ctrl->async_events list. Under normal operations the nvmet_async_event_work() updates again the ctrl->async_event_cmds and removes the corresponding struct nvmet_async_event from the list again. Though nvmet_sq_destroy() could be called which calls nvmet_async_events_free() which only updates the ctrl->async_event_cmds[] array. Add new functions nvmet_async_events_process() and nvmet_async_events_free() to process async events, update an array and the list. When we destroy submission queue after clearing the aen present on the ctrl->async list we also loop over ctrl->async_event_cmds[] for any requests posted by the host for which we don't have the AEN in the ctrl->async_events list by calling nvmet_async_event_process() and nvmet_async_events_free().

2020-02-04ALSA: hda - Fix DP-MST support for NVIDIA codecsNikhil Mahale1-31/+63
If dyn_pcm_assign is set, different jack objects are being created for pcm and pins. If dyn_pcm_assign is set, generic_hdmi_build_jack() calls into add_hdmi_jack_kctl() to create and track separate jack object for pcm. Like sync_eld_via_acomp(), hdmi_present_sense_via_verbs() also need to report status change of the pcm jack. Rename pin_idx_to_jack() to pin_idx_to_pcm_jack(). Update hdmi_present_sense_via_verbs() to report plug state of pcm jack object. Unlike sync_eld_via_acomp(), for !acomp drivers the pcm jack's plug state must be consistent with plug state of pin's jack.

2020-02-05nvmet: Fix controller use after freeIsrael Rukshin1-4/+9
After nvmet_install_queue() sets sq->ctrl calling to nvmet_sq_destroy() reduces the controller refcount. In case nvmet_install_queue() fails, calling to nvmet_ctrl_put() is done twice (at nvmet_sq_destroy and nvmet_execute_io_connect/nvmet_execute_admin_connect) instead of once for the queue which leads to use after free of the controller. Fix this by set NULL at sq->ctrl in case of a failure at nvmet_install_queue(). The bug leads to the following Call Trace: [65857.994862] refcount_t: underflow; use-after-free.

2020-02-04NFS: Fix memory leaksWenwen Wang1-2/+2
In _nfs42_proc_copy(), 'res->commit_res.verf' is allocated through kzalloc() if 'args->sync' is true. In the following code, if 'res->synchronous' is false, handle_async_copy() will be invoked. If an error occurs during the invocation, the following code will not be executed and the error will be returned . However, the allocated 'res->commit_res.verf' is not deallocated, leading to a memory leak. This is also true if the invocation of process_copy_commit() returns an error. To fix the above leaks, redirect the execution to the 'out' label if an error is encountered. Signed-off-by: Wenwen Wang <[email protected]> Signed-off-by: Anna Schumaker <[email protected]>
2020-02-04nfs: optimise readdir cache page invalidationDai Ngo2-2/+10
When the directory is large and it's being modified by one client while another client is doing the 'ls -l' on the same directory then the cache page invalidation from nfs_force_use_readdirplus causes the reading client to keep restarting READDIRPLUS from cookie 0 which causes the 'ls -l' to take a very long time to complete, possibly never completing. Currently when nfs_force_use_readdirplus is called to switch from READDIR to READDIRPLUS, it invalidates all the cached pages of the directory. This cache page invalidation causes the next nfs_readdir to re-read the directory content from cookie 0. This patch is to optimise the cache invalidation in nfs_force_use_readdirplus by only truncating the cached pages from last page index accessed to the end the file. It also marks the inode to delay invalidating all the cached page of the directory until the next initial nfs_readdir of the next 'ls' instance.

The sdma_queue_count increment should be done before execute_queues_cpsch(), which calls pm_calc_rlib_size() where sdma_queue_count is used to calculate whether over_subscription is triggered. With the previous code, when a SDMA queue is created, compute_queue_count in pm_calc_rlib_size() is one more than the actual compute queue number, because the queue_count has been incremented while sdma_queue_count has not.

2020-02-04drm/amd/display: Only enable cursor on pipes that need itNicholas Kazlauskas1-0/+30
[Why] In current code we're essentially drawing the cursor on every pipe that contains it. This only works when the planes have the same scaling for src to dest rect, otherwise we'll get "double cursor" where one cursor is incorrectly filtered and offset from the real position. [How] Without dedicated cursor planes on DCN we require at least one pipe that matches the scaling of the current timing. This is an optimization and workaround for the most common case where the top-most plane is not scaled but the bottom-most plane is scaled. Whenever a pipe has a parent pipe in the blending tree whose recout fully contains the current pipe we can disable the pipe. This only applies when the pipe is actually visible of course.

gtp hashtable size is received by user-space. So, this hashtable size could be too large. If so, kmalloc will internally print a warning message. This warning message is actually not necessary for the gtp module. So, this patch adds __GFP_NOWARN to avoid this message.

2020-02-04l2tp: Allow duplicate session creation with UDPRidge Kennedy1-1/+6
In the past it was possible to create multiple L2TPv3 sessions with the same session id as long as the sessions belonged to different tunnels. The resulting sessions had issues when used with IP encapsulated tunnels, but worked fine with UDP encapsulated ones. Some applications began to rely on this behaviour to avoid having to negotiate unique session ids. Some time ago a change was made to require session ids to be unique across all tunnels, breaking the applications making use of this "feature". This change relaxes the duplicate session id check to allow duplicates if both of the colliding sessions belong to UDP encapsulated tunnels.

As Eric noticed, tcindex_alloc_perfect_hash() uses cp->hash to compute the size of memory allocation, but cp->hash is set again after the allocation, this caused an out-of-bound access. So we have to move all cp->hash initialization and computation before the memory allocation. Move cp->mask and cp->shift together as cp->hash may need them for computation too.
