commit 526a4045 upstream. The usb device will autoresume from choose_wakeup() if it is autosuspended with the wrong wakeup setting, but below errors occur because usb3503 misc driver will switch to standby mode when suspended. As add USB_QUIRK_RESET_RESUME, it can stop setting wrong wakeup from autosuspend_check().

commit 934ef5ac upstream. This `usb_reset_device` command has been around since the driver was originally reverse engineered. It doesn't cause much issue on single interface CP210x devices, but on the CP2105 and CP2108 with 2 and 4 interfaces respectively it will cause instability on enumeration and delays enumeration noticably. There should be no reason to reset a device at startup, per the CP210x AN571 spec. Signed-off-by:

commit 50aea6fc upstream. The musb/cppi41 code installs a hrtimer to work around DMA completion interrupts that have fired too early on AM335x hardware. This timer is currently programmed to first fire 140 microseconds after the DMA completion callback. According to the commit which introduced it (a655f481, "usb: musb: musb_cppi41: handle pre-mature TX complete interrupt"), that value is is considered a 'rule of thumb' that worked well with the test case described in the commit log. Test show, however, that for USB audio devices and much smaller packet sizes, the timer has to fire earlier in order to correctly handle the audio stream. The original test case had output transfer sizes of 1514 bytes, and a delay of 140 microseconds. For audio devices with 24 bytes channel size, 3 microseconds seem to work well. Hence, let's assume that the time it takes to clear the bit correlates with the number of bytes transferred. The referenced commit log mentions such a suspicion as well. Let the timer fire in cppi41_channel->total_len/10 microseconds to correctly handle both cases. Also, shorten the interval in which the timer fires again in case of a non-empty early_tx list. With these changes in place, both FS and HS audio devices appear to work well on AM335x hardware. Signed-off-by:

commit b3fa7e77 upstream. The real fix is where we check the bytes we need against how much is remaining - we also need to check for a journal entry bigger than our buffer, we'll never write those and it would be bad if we tried to read one. Also improve the diagnostic messages. Signed-off-by:

commit ee1d9014 upstream. In __rtc_read_alarm(), if the alarm time retrieved by rtc_read_alarm_internal() from the device contains invalid values (e.g. month=2,mday=31) and the year not set (=-1), the initialization will loop infinitely because the year-fixing loop expects the time being invalid due to leap year. Fix reduces the loop to the leap years and adds final validity check. Signed-off-by:

commit 6e85bab6 upstream. In particular seeing zero in eft->month is problematic, as it results in -1 (converted to unsigned int, i.e. yielding 0xffffffff) getting passed to rtc_year_days(), where the value gets used as an array index (normally resulting in a crash). This was observed with the driver enabled on x86 on some Fujitsu system (with possibly not up to date firmware, but anyway). Perhaps efi_read_alarm() should not fail if neither enabled nor pending are set, but the returned time is invalid? Signed-off-by:

commit 42c22dbf upstream. This fix (not very clean though) should fix the long time USB3 issue that was spotted last year. The rational has been given by Hans de Goede: ---- I think the most likely cause for this is a firmware bug in the unifying receiver, likely a race condition. The most prominent difference between having a USB-2 device plugged into an EHCI (so USB-2 only) port versus an XHCI port will be inter packet timing. Specifically if you send packets (ie hid reports) one at a time, then with the EHCI controller their will be a significant pause between them, where with XHCI they will be very close together in time. The reason for this is the difference in EHCI / XHCI controller OS <-> driver interfaces. For non periodic endpoints (control, bulk) the EHCI uses a circular linked-list of commands in dma-memory, which it follows to execute commands, if the list is empty, it will go into an idle state and re-check periodically. The XHCI uses a ring of commands per endpoint, and if the OS places anything new on the ring it will do an ioport write, waking up the XHCI making it send the new packet immediately. For periodic transfers (isoc, interrupt) the delay between packets when sending one at a time (rather then queuing them up) will be even larger, because they need to be inserted into the EHCI schedule 2 ms in the future so the OS driver can be sure that the EHCI driver does not try to start executing the time slot in question before the insertion has completed. So a possible fix may be to insert a delay between packets being send to the receiver. ---- I tested this on a buggy Haswell USB 3.0 motherboard, and I always get the notification after adding the msleep.

commit 761ce533 upstream. Numerical values stored in the device tree are encoded in Big Endian and should be byte swapped when running in Little Endian. The RPA hotplug module should convert those values as well. Note that in rpaphp_get_drc_props(), the comparison between indexes[i+1] and *index is done using the BE values (whatever is the current endianess). This doesn't matter since we are checking for equality here. This way only the returned value is byte swapped. RPA also made RTAS calls which implies BE values to be used. According to the patch done in RTAS (http://patchwork.ozlabs.org/patch/336865), no additional conversion is required in RPA. Signed-off-by:

commit 5c0a0fc8 upstream. tipc_msg_build() calls skb_copy_to_linear_data_offset() to copy data from user space to kernel space. However, the latter function does in its turn call memcpy() to perform the actual copying. This poses an obvious security and robustness risk, since memcpy() never makes any validity check on the pointer it is copying from. To correct this, we the replace the offending function call with a call to memcpy_fromiovecend(), which uses copy_from_user() to perform the copying. Signed-off-by:

commit 3e548079 upstream. The fallback to 32-bit DMA mask is rather odd: if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) && !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) { *using_dac = true; } else { err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) goto release_regions; } This means we only try and set the coherent DMA mask if we failed to set a 32-bit DMA mask, and only if both fail do we fail the driver. Adjust this so that if either setting fails, we fail the driver - and thereby end up properly setting both the DMA mask and the coherent DMA mask in the fallback case. Signed-off-by:

commit 3de9e65f upstream. If new_mtu is very large then "new_mtu + ETH_HLEN + ETH_FCS_LEN" can wrap and the check on the next line can underflow. This is one of those bugs which can be triggered by the user if you have namespaces configured. Also since this is something the user can trigger then we don't want to have dev_err() message. This is a static checker fix and I'm not sure what the impact is. Signed-off-by:

In addition, on a single processor system, the ixgbe_qv_lock_napi loop shouldn't have to mdelay.

Since the watchdog_task can schedule other works apart from itself, it should be stopped first, but currently it is stopped after the reset_task.

The same issue has also been observed on the older e1000 cards. Here, we have increased the RESET_COUNT value to 50 because there are too many accesses to e1000 nic on stress tests to e1000 nic, it is not enough to set RESET_COUT 25.

commit 718a39eb upstream. The fallback to 32-bit DMA mask is rather odd: err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)); if (!err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64)); if (!err) pci_using_dac = 1; } else { err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { dev_err(&pdev->dev, "No usable DMA configuration, aborting\n"); goto err_dma; } } } This means we only set the coherent DMA mask in the fallback path if the DMA mask set failed, which is silly. This fixes it to set the coherent DMA mask only if dma_set_mask() succeeded, and to error out if either fails. Acked-by:
