The R-Car LVDS encoder units support dual-link operations by splitting the pixel output between the primary encoder and the companion encoder. Currently the companion encoder fails at probe time, causing the registration of the primary to fail as well, preventing the whole DU unit from being registered at all.

Problem is that the check is lockless, meaning another thread can issue a concurrent setsockopt(PACKET_TX_RING ) to flip tx_ring.pg_vec back to NULL.

2019-08-15dm integrity: fix a crash due to BUG_ON in __journal_read_write()Mikulas Patocka1-0/+15
Fix a crash that was introduced by the commit 724376a04d1a. The crash is reported here: https://gitlab.com/cryptsetup/cryptsetup/issues/468 When reading from the integrity device, the function dm_integrity_map_continue calls find_journal_node to find out if the location to read is present in the journal. Then, it calculates how many sectors are consecutively stored in the journal. Then, it locks the range with add_new_range and wait_and_add_new_range. The problem is that during wait_and_add_new_range, we hold no locks (we don't hold ic->endio_wait.lock and we don't hold a range lock), so the journal may change arbitrarily while wait_and_add_new_range sleeps. The code then goes to __journal_read_write and hits BUG_ON(journal_entry_get_sector(je) != logical_sector); because the journal has changed. In order to fix this bug, we need to re-check the journal location after wait_and_add_new_range. We restrict the length to one block in order to not complicate the code too much.

2019-08-15dm zoned: properly handle backing device failureDmitry Fomichev4-14/+110
dm-zoned is observed to lock up or livelock in case of hardware failure or some misconfiguration of the backing zoned device. This patch adds a new dm-zoned target function that checks the status of the backing device. If the request queue of the backing device is found to be in dying state or the SCSI backing device enters offline state, the health check code sets a dm-zoned target flag prompting all further incoming I/O to be rejected. In order to detect backing device failures timely, this new function is called in the request mapping path, at the beginning of every reclaim run and before performing any metadata I/O. The proper way out of this situation is to do dmsetup remove <dm-zoned target> and recreate the target when the problem with the backing device is resolved.

2019-08-15dm zoned: improve error handling in i/o map codeDmitry Fomichev1-6/+16
Some errors are ignored in the I/O path during queueing chunks for processing by chunk works. Since at least these errors are transient in nature, it should be possible to retry the failed incoming commands. The fix - Errors that can happen while queueing chunks are carried upwards to the main mapping function and it now returns DM_MAPIO_REQUEUE for any incoming requests that can not be properly queued. Error logging/debug messages are added where needed.

2019-08-15dm zoned: improve error handling in reclaimDmitry Fomichev2-11/+21
There are several places in reclaim code where errors are not propagated to the main function, dmz_reclaim(). This function is responsible for unlocking zones that might be still locked at the end of any failed reclaim iterations. As the result, some device zones may be left permanently locked for reclaim, degrading target's capability to reclaim zones. This patch fixes these issues as follows - Make sure that dmz_reclaim_buf(), dmz_reclaim_seq_data() and dmz_reclaim_rnd_data() return error codes to the caller. dmz_reclaim() function is renamed to dmz_do_reclaim() to avoid clashing with "struct dmz_reclaim" and is modified to return the error to the caller. dmz_get_zone_for_reclaim() now returns an error instead of NULL pointer and reclaim code checks for that error. Error logging/debug messages are added where necessary.

2019-08-15dm kcopyd: always complete failed jobsDmitry Fomichev1-1/+4
This patch fixes a problem in dm-kcopyd that may leave jobs in complete queue indefinitely in the event of backing storage failure. This behavior has been observed while running 100% write file fio workload against an XFS volume created on top of a dm-zoned target device. If the underlying storage of dm-zoned goes to offline state under I/O, kcopyd sometimes never issues the end copy callback and dm-zoned reclaim work hangs indefinitely waiting for that completion. This behavior was traced down to the error handling code in process_jobs() function that places the failed job to complete_jobs queue, but doesn't wake up the job handler. In case of backing device failure, all outstanding jobs may end up going to complete_jobs queue via this code path and then stay there forever because there are no more successful I/O jobs to wake up the job handler. This patch adds a wake() call to always wake up kcopyd job wait queue for all I/O jobs that fail before dm_io() gets called for that job. The patch also sets the write error status in all sub jobs that are failed because their master job has failed.

Revert the commit bd293d071ffe65e645b4d8104f9d8fe15ea13862. The proper fix has been made available with commit d0a255e795ab ("loop: set PF_MEMALLOC_NOIO for the worker thread"). Note that the fix offered by commit bd293d071ffe doesn't really prevent the deadlock from occuring - if we look at the stacktrace reported by Junxiao Bi, we see that it hangs in bit_wait_io and not on the mutex - i.e. it has already successfully taken the mutex. Changing the mutex from mutex_lock to mutex_trylock won't help with deadlocks that happen afterwards.

This patch may fix two issues: First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into defer list to delay execution, but link io will be actively scheduled to run by calling io_queue_sqe.

2019-08-15io_uring: fix manual setup of iov_iter for fixed buffersAleix Roca Nonell1-3/+1
Commit bd11b3a391e3 ("io_uring: don't use iov_iter_advance() for fixed buffers") introduced an optimization to avoid using the slow iov_iter_advance by manually populating the iov_iter iterator in some cases. However, the computation of the iterator count field was erroneous: The first bvec was always accounted for an extent of page size even if the bvec length was smaller. In consequence, some I/O operations on fixed buffers were unable to operate on the full extent of the buffer, consistently skipping some bytes at the end of it.

2019-08-15PCI: Reset both NVIDIA GPU and HDA in ThinkPad P50 workaroundLyude Paul1-1/+1
quirk_reset_lenovo_thinkpad_50_nvgpu() resets NVIDIA GPUs to work around an apparent BIOS defect. It previously used pci_reset_function(), and the available method was a bus reset, which was fine because there was only one function on the bus. After b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), there are now two functions (the HDA controller and the GPU itself) on the bus, so the reset fails. Use pci_reset_bus() explicitly instead of pci_reset_function() since it's OK to reset both devices.

2019-08-15USB: serial: option: Add Motorola modem UARTsTony Lindgren1-0/+5
On Motorola Mapphone devices such as Droid 4 there are five USB ports that do not use the same layout as Gobi 1K/2K/etc devices listed in qcserial.c. So we should use qcaux.c or option.c as noted by Dan Williams <[email protected]>. As the Motorola USB serial ports have an interrupt endpoint as shown with lsusb -v, we should use option.c instead of qcaux.c as pointed out by Johan Hovold <[email protected]>. The ff/ff/ff interfaces seem to always be UARTs on Motorola devices. For the other interfaces, class 0x0a (CDC Data) should not in general be added as they are typically part of a multi-interface function as noted earlier by Bjørn Mork <[email protected]>. However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a class is only used for flashing the modem firmware, and there are no other interfaces. So I've added that too with more details below as it works just fine. The ttyUSB ports on Droid 4 are: ttyUSB0 DIAG, CQDM-capable ttyUSB1 MUX or NMEA, no response ttyUSB2 MUX or NMEA, no response ttyUSB3 TCMD ttyUSB4 AT-capable The ttyUSB0 is detected as QCDM capable by ModemManager. I think it's only used for debugging with ModemManager --debug for sending custom AT commands though. ModemManager already can manage data connection using the USB QMI ports that are already handled by the qmi_wwan.c driver. To enable the MUX or NMEA ports, it seems that something needs to be done additionally to enable them, maybe via the DIAG or TCMD port. It might be just a NVRAM setting somewhere, but I have no idea what NVRAM settings may need changing for that. The TCMD port seems to be a Motorola custom protocol for testing the modem and to configure it's NVRAM and seems to work just fine based on a quick test with a minimal tcmdrw tool I wrote. The voice modem AT-capable port seems to provide only partial support, and no PM support compared to the TS 27.010 based UART wired directly to the modem. The UARTs added with this change are the same product IDs as the Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't have any mdm9600 based devices, so I have only tested these on mdm6600 based droid 4. Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android Linux kernel driver moto_flashqsc.c just seems to change the port->bulk_out_size to 8K from the default. And is only used for flashing the modem firmware it seems. I've verified that flashing the modem with signed firmware works just fine with the option driver after manually toggling the GPIO pins, so I've added droid 4 modem flashing mode to the option driver. I've not added the other devices listed in moto_flashqsc.c in case they really need different port->bulk_out_size. Those can be added as they get tested to work for flashing the modem. After this patch the output of /sys/kernel/debug/usb/devices has the following for normal 22b8:2a70 mode including the related qmi_wwan interfaces: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=22b8 ProdID=2a70 Rev= 0.00 S: Manufacturer=Motorola, Incorporated S: Product=Flash MZ600 C:* #Ifs= 9 Cfg#= 1 Atr=e0 MxPwr=500mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

2019-08-15MAINTAINERS, x86/CPU: Tony Luck will maintain asm/intel-family.hTony Luck1-0/+7
There are a few different subsystems in the kernel that depend on model specific behaviour (perf, EDAC, power, ...). Easier for just one person to have the task to get new model numbers included instead of having these groups trip over each other to do it.

2019-08-15selftests: kvm: fix vmx_set_nested_state_testPaolo Bonzini1-3/+14
vmx_set_nested_state_test is trying to use the KVM_STATE_NESTED_EVMCS without enabling enlightened VMCS first. Correct the outcome of the test, and actually test that it succeeds after the capability is enabled. Signed-off-by: Paolo Bonzini <[email protected]>
