2020-08-06Input: exc3000 - add support to query model and fw_versionSebastian Reichel2-1/+162
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

2020-08-06Input: ims-pcu - return error code rather than -ENOMEMColin Ian King1-1/+1
Currently the assignment of -ENOMEM to error is redundant because error is not being read and -ENOMEM is being hard coded as an error return. Fix this by returning the error code in variable 'error'; this also allows the error code from a failed call to input_register_device to be preserved and returned to the caller rather than just returning a possibly inappropriate -ENOMEM.

2020-08-06Revert "x86/mm/64: Do not sync vmalloc/ioremap mappings"Linus Torvalds2-0/+7
This reverts commit 8bb9bf242d1fee925636353807c511d54fde8986. It seems the vmalloc page tables aren't always preallocated in all situations, because Jason Donenfeld reports an oops with this commit: BUG: unable to handle page fault for address: ffffe8ffffd00608 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP CPU: 2 PID: 22 Comm: kworker/2:0 Not tainted 5.8.0+ #154 RIP: process_one_work+0x2c/0x2d0 Code: 41 56 41 55 41 54 55 48 89 f5 53 48 89 fb 48 83 ec 08 48 8b 06 4c 8b 67 40 49 89 c6 45 30 f6 a8 04 b8 00 00 00 00 4c 0f 44 f0 <49> 8b 46 08 44 8b a8 00 01 05 Call Trace: worker_thread+0x4b/0x3b0 ? rescuer_thread+0x360/0x360 kthread+0x116/0x140 ? __kthread_create_worker+0x110/0x110 ret_from_fork+0x1f/0x30 CR2: ffffe8ffffd00608 and that page fault address is right in that vmalloc space, and we clearly don't have a PGD/P4D entry for it. Looking at the "Code:" line, the actual fault seems to come from the 'pwq->wq' dereference at the top of the process_one_work() function: struct pool_workqueue *pwq = get_work_pwq(work); struct worker_pool *pool = worker->pool; bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE; so 'struct pool_workqueue *pwq' is the allocation that hasn't been synchronized across CPUs. Just revert for now, while Joerg figures out the cause. Reported-and-bisected-by: Jason A.

2020-08-06fs: dlm: implement tcp graceful shutdownAlexander Aring1-5/+72
During my code inspection I saw there is no implementation of a graceful shutdown for tcp. This patch will introduce a graceful shutdown for tcp connections. The shutdown is implemented synchronized as dlm_lowcomms_stop() is called to end all dlm communication. After shutdown is done, a lot of flush and closing functionality will be called. However I don't see a problem with that. The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if timeout a force close will be exectued.

2020-08-06fs: dlm: change handling of reconnectsAlexander Aring1-15/+10
This patch changes the handling of reconnects. At first we only close the connection related to the communication failure. If we get a new connection for an already existing connection we close the existing connection and take the new one. This patch improves significantly the stability of tcp connections while running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm messages e.g. on a gfs2 mount with many files. My test setup shows that a deadlock is "more" unlikely. Before this patch I wasn't able to get not a deadlock after 5 seconds. After this patch my observation is that it's more likely to survive after 5 seconds and more, but still a deadlock occurs after certain time. My guess is that there are still "segments" inside the tcp writequeue or retransmit queue which get dropped when receiving a tcp reset [1]. Hard to reproduce because the right message need to be inside these queues, which might even be in the 5 first seconds with this patch.

Move parse_clockid and all needed clcckid related stuff into clockid object. We are going to add clockid_name function in following change, so it's better it's placed in separated object and not in builtin-record.c. No functional change is intended.
