| * usb: host: xhci-plat: Fix timeout on removal of hot pluggable xhci controllersGuenter Roeck2017-03-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit 98d74f9ceaef ("xhci: fix 10 second timeout on removal of PCI hotpluggable xhci controllers") fixes a problem with hot pluggable PCI xhci controllers which can result in excessive timeouts, to the point where the system reports a deadlock. The same problem is seen with hot pluggable xhci controllers using the xhci-plat driver, such as the driver used for Type-C ports on rk3399. Similar to hot-pluggable PCI controllers, the driver for this chip removes the xhci controller from the system when the Type-C cable is disconnected. The solution for PCI devices works just as well for non-PCI devices and avoids the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, we might get a completion for a TRB which is left with HWO bit. Even in these cases, we should increment req->remaining to properly report total transferred size. I noticed this while debuggin a separate problem seen with MSC tests from USBCV. Sometimes we would erroneously report a completion for a 512-byte transfer when, in reality, we transferred 0 bytes. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
| * | usb: gadget: udc: net2280: Fix tmp reusage in net2280 driverRaz Manor2017-03-061-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the function scan_dma_completions() there is a reusage of tmp variable. That coused a wrong value being used in some case when reading a short packet terminated transaction from an endpoint, in 2 concecutive reads. This was my logic for the patch: The req->td->dmadesc equals to 0 iff: -- There was a transaction ending with a short packet, and -- The read() to read it was shorter than the transaction length, and -- The read() to complete it is longer than the residue. I believe this is true from the printouts of various cases, but I can't be positive it is correct. Entering this if, there should be no more data in the endpoint (a short packet terminated the transaction). If there is, the transaction wasn't really done and we should exit and wait for it to finish entirely. That is the inner if. That inner if should never happen, but it is there to be on the safe side. That is why it is marked with the comment /* paranoia */. The size of the data available in the endpoint is ep->dma->dmacount and it is read to tmp. This entire clause is based on my own educated guesses. If we passed that inner if without breaking in the original code, than tmp & DMA_BYTE_MASK_COUNT== 0. That means we will always pass dma bytes count of 0 to dma_done(), meaning all the requested bytes were read. dma_done() reports back to the upper layer that the request (read()) was done and how many bytes were read. In the original code that would always be the request size, regardless of the actual size of the data. That did not make sense to me at all. However, the original value of tmp is req->td->dmacount, which is the dmacount value when the request's dma transaction was finished. And that is a much more reasonable value to report back to the caller. To recreate the problem: Read from a bulk out endpoint in a loop, 1024 * n bytes in each iteration. Connect the PLX to a host you can control. Send to that endpoint 1024 * n + x bytes, such that 0 < x < 1024 * n and (x % 1024) != 0 You would expect the first read() to return 1024 * n and the second read() to return x. But you will get the first read to return 1024 * n and the second one to return 1024 * n. That is true for every positive integer n.

The bad commit was causing a duplicate response to be sent with incorrect response data thus causing UVC probe to fail at the host and broken control transfer endpoint at the gadget.

With that we also need to ignore all TRBs used by the request, however TRBs can only be modified after completion of END_TRANSFER command. So what we have to do here is wait for END_TRANSFER completion and only after that jump over TRBs by clearing HWO and incrementing dequeue pointer. Note that we have 2 possible types of transfers here: i) Linear buffer request ii) SG-list based request SG-list based requests will have r->num_pending_sgs set to a valid number (> 0). Linear requests, normally use a single TRB. For each of these two cases, if r->unaligned flag is set, one extra TRB has been used to align transfer size to wMaxPacketSize. All of these cases need to be taken into consideration so we don't mess up our TRB ring pointers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <linux/sched/signal.h> We are going to split <linux/sched/signal.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/signal.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

* | lib/vsprintf.c: remove %Z supportAlexey Dobriyan2017-02-287-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
