2021-05-21drivers: base: Fix device link removalRafael J. Wysocki
When device_link_free() drops references to the supplier and consumer devices of the device link going away and the reference being dropped turns out to be the last one for any of those device objects, its ->release callback will be invoked and it may sleep which goes against the SRCU callback execution requirements. To address this issue, make the device link removal code carry out the device_link_free() actions preceded by SRCU synchronization from a separate work item (the "long" workqueue is used for that, because it does not matter when the device link memory is released and it may take time to get to that point) instead of using SRCU callbacks. While at it, make the code work analogously when SRCU is not enabled to reduce the differences between the SRCU and non-SRCU cases.

2021-05-21perf scripts python: exported-sql-viewer.py: Fix warning displayAdrian Hunter
Deprecation warnings are useful only for the developer, not an end user. Display warnings only when requested using the python -W option. This stops the display of warnings like: tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning: an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python. err = app.exec_() Since the warning can be fixed only in PySide2, we must wait for it to be finally fixed there.

The 'Array' class is present in more than one python standard library.

2021-05-21serial: rp2: use 'request_firmware' instead of 'request_firmware_nowait'Zheyu Ma
In 'rp2_probe', the driver registers 'rp2_uart_interrupt' then calls 'rp2_fw_cb' through 'request_firmware_nowait'. In 'rp2_fw_cb', if the firmware don't exists, function just return without initializing ports of 'rp2_card'. But now the interrupt handler function has been registered, and when an interrupt comes, 'rp2_uart_interrupt' may access those ports then causing NULL pointer dereference or other bugs. Because the driver does some initialization work in 'rp2_fw_cb', in order to make the driver ready to handle interrupts, 'request_firmware' should be used instead of asynchronous 'request_firmware_nowait'. This report reveals it: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

The alpha and sparc siginfo structure layout had changed with the addition of SIGTRAP TRAP_PERF and the new field si_perf. The reason only alpha and sparc were affected is that they are the only architectures that use si_trapno. Looking deeper it was discovered that si_trapno is used for only a few select signals on alpha and sparc, and that none of the other _sigfault fields past si_addr are used at all. Which means technically no regression on alpha and sparc. While the alignment concerns might be dismissed the abuse of si_errno by SIGTRAP TRAP_PERF does have the potential to cause regressions in existing userspace. While we still have time before userspace starts using and depending on the new definition siginfo for SIGTRAP TRAP_PERF this set of changes cleans up siginfo_t. - The si_trapno field is demoted from magic alpha and sparc status and made an ordinary union member of the _sigfault member of siginfo_t.

The return value of hga_card_detect() is not properly handled causing the probe to succeed even though hga_card_detect() failed. Since probe succeeds, hgafb_open() can be called which will end up operating on an unmapped hga_vram. This results in an out-of-bounds access as reported by kernel test robot [1]. To fix this, correctly detect failure of hga_card_detect() by checking for a non-zero error code.

2021-05-21usb: typec: ucsi: Clear pending after acking connector changeBjorn Andersson
It's possible that the interrupt handler for the UCSI driver signals a connector changes after the handler clears the PENDING bit, but before it has sent the acknowledge request. The result is that the handler is invoked yet again, to ack the same connector change. At least some versions of the Qualcomm UCSI firmware will not handle the second - "spurious" - acknowledgment gracefully. So make sure to not clear the pending flag until the change is acknowledged. Any connector changes coming in after the acknowledgment, that would have the pending flag incorrectly cleared, would afaict be covered by the subsequent connector status check.

2021-05-21usb: dwc3: gadget: Properly track pending and queued SGThinh Nguyen
The driver incorrectly uses req->num_pending_sgs to track both the number of pending and queued SG entries. It only prepares the next request if the previous is done, and it doesn't update num_pending_sgs until there is TRB completion interrupt. This may starve the controller of more TRBs until the num_pending_sgs is decremented. Fix this by decrementing the num_pending_sgs after they are queued and properly track both num_mapped_sgs and num_queued_sgs.

2021-05-21USB: usbfs: Don't WARN about excessively large memory allocationsAlan Stern
Syzbot found that the kernel generates a WARNing if the user tries to submit a bulk transfer through usbfs with a buffer that is way too large. This isn't a bug in the kernel; it's merely an invalid request from the user and the usbfs code does handle it correctly. In theory the same thing can happen with async transfers, or with the packet descriptor table for isochronous transfers. To prevent the MM subsystem from complaining about these bad allocation requests, add the __GFP_NOWARN flag to the kmalloc calls for these buffers.

2021-05-21spi: sc18is602: implement .max_{transfer,message}_size() for the controllerVladimir Oltean
Allow SPI peripherals attached to this controller to know what is the maximum transfer size and message size, so they can limit their transfer lengths properly in case they are otherwise capable of larger transfer sizes. For the sc18is602, this is 200 bytes in both cases, since as far as I understand, it isn't possible to tell the controller to keep the chip select asserted after the STOP command is sent. The controller can support SPI messages larger than 200 bytes if cs_change is set for individual transfers such that the portions with chip select asserted are never longer than 200 bytes. What is not supported is just SPI messages with a continuous chip select larger than 200. I don't think it is possible to express this using the current API, so drivers which do send SPI messages with cs_change can safely just look at the max_transfer_size limit. An example of user for this is sja1105_xfer() in drivers/net/dsa/sja1105/sja1105_spi.c which sends by default 64 * 4 = 256 byte transfers.

2021-05-21spi: sc18is602: don't consider the chip select byte in sc18is602_check_transferVladimir Oltean
For each spi_message, the sc18is602 I2C-to-SPI bridge driver checks the length of each spi_transfer against 200 (the size of the chip's internal buffer) minus hw->tlen (the number of bytes transferred so far). The first byte of the transferred data is the Function ID (the SPI slave's chip select) and as per the documentation of the chip: https://www.nxp.com/docs/en/data-sheet/SC18IS602B.pdf the data buffer is up to 200 bytes deep _without_ accounting for the Function ID byte. However, in sc18is602_txrx(), the driver keeps the Function ID as part of the buffer, and increments hw->tlen from 0 to 1. Combined with the check in sc18is602_check_transfer, this prevents us from issuing a transfer that has exactly 200 bytes in size, but only 199. Adjust the check function to reflect that the Function ID is not part of the 200 byte deep data buffer.

Undo overriding the function to zero and instead make sure that VFs at function zero remain alone in their slot.
