2018-12-07nvme: validate controller state before rescheduling keep aliveJames Smart1-1/+9
Delete operations are seeing NULL pointer references in call_timer_fn. Tracking these back, the timer appears to be the keep alive timer. nvme_keep_alive_work() which is tied to the timer that is cancelled by nvme_stop_keep_alive(), simply starts the keep alive io but doesn't wait for it's completion. So nvme_stop_keep_alive() only stops a timer when it's pending. When a keep alive is in flight, there is no timer running and the nvme_stop_keep_alive() will have no affect on the keep alive io. Thus, if the io completes successfully, the keep alive timer will be rescheduled. In the failure case, delete is called, the controller state is changed, the nvme_stop_keep_alive() is called while the io is outstanding, and the delete path continues on. The keep alive happens to successfully complete before the delete paths mark it as aborted as part of the queue termination, so the timer is restarted. The delete paths then tear down the controller, and later on the timer code fires and the timer entry is now corrupt. Fix by validating the controller state before rescheduling the keep alive. Testing with the fix has confirmed the condition above was hit.

2018-12-06i2c: uniphier-f: fill TX-FIFO only in IRQ handler for repeated STARTMasahiro Yamada1-4/+9
- For a repeated START condition, this controller starts data transfer immediately after the slave address is written to the TX-FIFO. - Once the TX-FIFO empty interrupt is asserted, the controller makes a pause even if additional data are written to the TX-FIFO. Given those circumstances, the data after a repeated START may not be transferred if the interrupt is asserted while the TX-FIFO is being filled up. A more reliable way is to append TX data only in the interrupt handler. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2018-12-06i2c: uniphier-f: fix timeout error after reading 8 bytesMasahiro Yamada1-3/+14
I was totally screwed up in commit eaba68785c2d ("i2c: uniphier-f: fix race condition when IRQ is cleared"). Since that commit, if the number of read bytes is multiple of the FIFO size (8, 16, 24... bytes), the STOP condition could be issued twice, depending on the timing. If this happens, the controller will go wrong, resulting in the timeout error. It was more than 3 years ago when I wrote this driver, so my memory about this hardware was vague. Please let me correct the description in the commit log of eaba68785c2d. Clearing the IRQ status on exiting the IRQ handler is absolutely fine. This controller makes a pause while any IRQ status is asserted. If the IRQ status is cleared first, the hardware may start the next transaction before the IRQ handler finishes what it supposed to do. This partially reverts the bad commit with clear comments so that I will never repeat this mistake. I also investigated what is happening at the last moment of the read mode. The UNIPHIER_FI2C_INT_RF interrupt is asserted a bit earlier (by half a period of the clock cycle) than UNIPHIER_FI2C_INT_RB. I consulted a hardware engineer, and I got the following information: UNIPHIER_FI2C_INT_RF asserted at the falling edge of SCL at the 8th bit. UNIPHIER_FI2C_INT_RB asserted at the rising edge of SCL at the 9th (ACK) bit. In order to avoid calling uniphier_fi2c_stop() twice, check the latter interrupt. I also commented this because it is obscure hardware internal.

2018-12-06i2c: axxia: properly handle master timeoutAdamski, Krzysztof (Nokia - PL/Wroclaw)1-11/+29
According to Intel (R) Axxia TM Lionfish Communication Processor Peripheral Subsystem Hardware Reference Manual, the AXXIA I2C module have a programmable Master Wait Timer, which among others, checks the time between commands send in manual mode. When a timeout (25ms) passes, TSS bit is set in Master Interrupt Status register and a Stop command is issued by the hardware. The axxia_i2c_xfer(), does not properly handle this situation, however. For each message a separate axxia_i2c_xfer_msg() is called and this function incorrectly assumes that any interrupt might happen only when waiting for completion. This is mostly correct but there is one exception - a master timeout can trigger if enough time has passed between individual transfers. It will, by definition, happen between transfers when the interrupts are disabled by the code. If that happens, the hardware issues Stop command. The interrupt indicating timeout will not be triggered as soon as we enable them since the Master Interrupt Status is cleared when master mode is entered again (which happens before enabling irqs) meaning this error is lost and the transfer is continued even though the Stop was issued on the bus. The subsequent operations completes without error but a bogus value (0xFF in case of read) is read as the client device is confused because aborted transfer. No error is returned from master_xfer() making caller believe that a valid value was read. To fix the problem, the TSS bit (indicating timeout) in Master Interrupt Status register is checked before each transfer. If it is set, there was a timeout before this transfer and (as described above) the hardware already issued Stop command so the transaction should be aborted thus -ETIMEOUT is returned from the master_xfer() callback. In order to be sure no timeout was issued we can't just read the status just before starting new transaction as there will always be a small window of time (few CPU cycles at best) where this might still happen. For this reason we have to temporally disable the timer before checking for TSS bit. Disabling it will, however, clear the TSS bit so in order to preserve that information, we have to read it in ISR so we have to ensure that the TSS interrupt is not masked between transfers of one transaction. There is no need to call bus recovery or controller reinitialization if that happens so it's skipped.

2018-12-05dmaengine: cppi41: delete channel from pending list when stop channelBin Liu1-1/+15
The driver defines three states for a cppi channel. - idle: .chan_busy == 0 && not in .pending list - pending: .chan_busy == 0 && in .pending list - busy: .chan_busy == 1 && not in .pending list There are cases in which the cppi channel could be in the pending state when cppi41_dma_issue_pending() is called after cppi41_runtime_suspend() is called. cppi41_stop_chan() has a bug for these cases to set channels to idle state. It only checks the .chan_busy flag, but not the .pending list, then later when cppi41_runtime_resume() is called the channels in .pending list will be transitioned to busy state. Removing channels from the .pending list solves the problem.

2018-12-05dmaengine: imx-sdma: implement channel termination via workerLucas Stach1-13/+38
The dmaengine documentation states that device_terminate_all may be asynchronous and need not wait for the active transfers to stop. This allows us to move most of the functionality currently implemented in the sdma channel termination function to run in a worker, outside of any atomic context. Moving this out of atomic context has two benefits: we can now sleep while waiting for the channel to terminate, instead of busy waiting and the freeing of the dma descriptors happens with IRQs enabled, getting rid of a warning in the dma mapping code. As the termination is now async, we need to implement the device_synchronize dma engine function which simply waits for the worker to finish its execution.

This reverts commit fe5b85c656bc. The SDMA engine needs the descriptors to be contiguous in memory. As the dma pool API is only able to provide a single descriptor per alloc invocation there is no guarantee that multiple descriptors satisfy this requirement. Also the code in question is broken as it only allocates memory for a single descriptor, without looking at the number of descriptors required for the transfer, leading to out-of-bounds accesses when the descriptors are written.

2018-12-04drm/amd/display: Fix overflow/truncation from strncpy.Nicholas Kazlauskas1-3/+3
[Why] New GCC warnings for stringop-truncation and stringop-overflow help catch common misuse of strncpy. This patch suppresses these warnings by fixing bugs identified by them. [How] Since the parameter passed for name in amdpgu_dm_create_common_mode has no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then mode->name will not be null-terminated. The truncation in fill_audio_info won't actually occur (and the string will be null-terminated since the buffer is initialized to zero), but the warning can be suppressed by using the proper buffer size. This patch fixes both issues by using the real size for the buffer and making use of strscpy (which always terminates).

2018-12-03Input: omap-keypad - fix keyboard debounce configurationTony Lindgren1-4/+14
I noticed that the Android v3.0.8 kernel on droid4 is using different keypad values from the mainline kernel and does not have issues with keys occasionally being stuck until pressed again. Turns out there was an earlier patch posted to fix this as "Input: omap-keypad: errata i689: Correct debounce time", but it was never reposted to fix use macros for timing calculations. This updated version is using macros, and also fixes the use of the input clock rate to use 32768KiHz instead of 32000KiHz. And we want to use the known good Android kernel values of 3 and 6 instead of 2 and 6 in the earlier patch.
