2016-10-23xhci: fix usb2 resume timing and races.Mathias Nyman
[ Upstream commit f69115fdbc1ac0718e7d19ad3caa3da2ecfe1c96 ] According to USB 2 specs ports need to signal resume for at least 20ms, in practice even longer, before moving to U0 state. Both host and devices can initiate resume. On device initiated resume, a port status interrupt with the port in resume state in issued. The interrupt handler tags a resume_done[port] timestamp with current time + USB_RESUME_TIMEOUT, and kick roothub timer. Root hub timer requests for port status, finds the port in resume state, checks if resume_done[port] timestamp passed, and set port to U0 state. On host initiated resume, current code sets the port to resume state, sleep 20ms, and finally sets the port to U0 state. This should also be changed to work in a similar way as the device initiated resume, with timestamp tagging, but that is not yet tested and will be a separate fix later. There are a few issues with this approach 1. A host initiated resume will also generate a resume event. The event handler will find the port in resume state, believe it's a device initiated resume, and act accordingly. 2. A port status request might cut the resume signalling short if a get_port_status request is handled during the host resume signalling. The port will be found in resume state. The timestamp is not set leading to time_after_eq(jiffies, timestamp) returning true, as timestamp = 0. get_port_status will proceed with moving the port to U0. 3. If an error, or anything else happens to the port during device initiated resume signalling it will leave all the device resume parameters hanging uncleared, preventing further suspend, returning -EBUSY, and cause the pm thread to busyloop trying to enter suspend. Fix this by using the existing resuming_ports bitfield to indicate that resume signalling timing is taken care of. Check if the resume_done[port] is set before using it for timestamp comparison, and also clear out any resume signalling related variables if port is not in U0 or Resume state This issue was discovered when a PM thread busylooped, trying to runtime suspend the xhci USB 2 roothub on a Dell XPS Cc: stable <stable@vger.kernel.org> Reported-by: Daniel J Blueman <daniel@quora.org> Tested-by: Daniel J Blueman <daniel@quora.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>
2016-10-03can: flexcan: fix resume functionFabio Estevam
[ Upstream commit 4de349e786a3a2d51bd02d56f3de151bbc3c3df9 ] On a imx6ul-pico board the following error is seen during system suspend: dpm_run_callback(): platform_pm_resume+0x0/0x54 returns -110 PM: Device 2090000.flexcan failed to resume: error -110 The reason for this suspend error is because when the CAN interface is not active the clocks are disabled and then flexcan_chip_enable() will always fail due to a timeout error. In order to fix this issue, only call flexcan_chip_enable/disable() when the CAN interface is active. Based on a patch from Dong Aisheng in the NXP kernel.

2016-10-03drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen
[ Upstream commit 47a66e45d7a7613322549c2475ea9d809baaf514 ] Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Kristian H.

2016-10-03USB: change bInterval default to 10 msAlan Stern
[ Upstream commit 08c5cd37480f59ea39682f4585d92269be6b1424 ] Some full-speed mceusb infrared transceivers contain invalid endpoint descriptors for their interrupt endpoints, with bInterval set to 0. In the past they have worked out okay with the mceusb driver, because the driver sets the bInterval field in the descriptor to 1, overwriting whatever value may have been there before. However, this approach was never sanctioned by the USB core, and in fact it does not work with xHCI controllers, because they use the bInterval value that was present when the configuration was installed. Currently usbcore uses 32 ms as the default interval if the value in the endpoint descriptor is invalid. It turns out that these IR transceivers don't work properly unless the interval is set to 10 ms or below. To work around this mceusb problem, this patch changes the endpoint-descriptor parsing routine, making the default interval value be 10 ms rather than 32 ms.

[ Upstream commit 6f3c4fb6d05e63c9c6d8968302491c3a5457be61 ] Problems with the signal integrity of the high speed USB data lines or noise on reference ground lines can cause the i.MX6 USB controller to violate USB specs and exhibit unexpected behavior. It was observed that USBi_UI interrupts were triggered first and when isr_setup_status_phase was called, ci->status was NULL, which lead to a NULL pointer dereference kernel panic. This patch fixes the kernel panic, emits a warning once and returns -EPIPE to halt the device and let the host get stalled. It also adds a comment to point people, who are experiencing this issue, to their USB hardware design.

[ Upstream commit 519d8bd4b5d3d82c413eac5bb42b106bb4b9ec15 ] The previous driver is possible to stop the transfer wrongly. For example: 1) An interrupt happens, but not BRDY interruption. 2) Read INTSTS0. And than state->intsts0 is not set to BRDY. 3) BRDY is set to 1 here. 4) Read BRDYSTS. 5) Clear the BRDYSTS. And then. the BRDY is cleared wrongly. Remarks: - The INTSTS0.BRDY is read only. - If any bits of BRDYSTS are set to 1, the BRDY is set to 1. - If BRDYSTS is 0, the BRDY is set to 0. So, this patch adds condition to avoid such situation. (And about NRDYSTS, this is not used for now. But, avoiding any side effects, this patch doesn't touch it.)

[ Upstream commit 4e870e948fbabf62b78e8410f04c67703e7c816b ] When dm-crypt processes writes, it allocates a new bio in crypt_alloc_buffer().

If the incoming bio is larger, bio_alloc_bioset() fails and an error is returned. To avoid the error, we test for a too large bio in the function crypt_map() and use dm_accept_partial_bio() to split the bio. dm_accept_partial_bio() trims the current bio to the desired size and asks DM core to send another bio with the rest of the data.

2016-09-12USB: avoid left shift by -1Alan Stern
[ Upstream commit 53e5f36fbd2453ad69a3369a1db62dc06c30a4aa ] UBSAN complains about a left shift by -1 in proc_do_submiturb(). This can occur when an URB is submitted for a bulk or control endpoint on a high-speed device, since the code doesn't bother to check the endpoint type; normally only interrupt or isochronous endpoints have a nonzero bInterval value. Aside from the fact that the operation is illegal, it shouldn't matter because the result isn't used. Still, in theory it could cause a hardware exception or other problem, so we should work around it. This patch avoids doing the left shift unless the shift amount is >= 0. The same piece of code has another problem. When checking the device speed (the exponential encoding for interrupt endpoints is used only by high-speed or faster devices), we need to look for speed >= USB_SPEED_SUPER as well as speed == USB_SPEED HIGH. The patch adds this check.

2016-09-12staging: comedi: ni_mio_common: fix AO inttrig backwards compatibilityIan Abbott
[ Upstream commit f0f4b0cc3a8cffd983f5940d46cd0227f3f5710a ] Commit ebb657babfa9 ("staging: comedi: ni_mio_common: clarify the cmd->start_arg validation and use") introduced a backwards compatibility issue in the use of asynchronous commands on the AO subdevice when `start_src` is `TRIG_EXT`. Valid values for `start_src` are `TRIG_INT` (for internal, software trigger), and `TRIG_EXT` (for external trigger). When set to `TRIG_EXT`. In both cases, the driver relies on an internal, software trigger to set things up (allowing the user application to write sufficient samples to the data buffer before the trigger), so it acts as a software "pre-trigger" in the `TRIG_EXT` case. The software trigger is handled by `ni_ao_inttrig()`. Prior to the above change, when `start_src` was `TRIG_INT`, `start_arg` was required to be 0, and `ni_ao_inttrig()` checked that the software trigger number was also 0. After the above change, when `start_src` was `TRIG_INT`, any value was allowed for `start_arg`, and `ni_ao_inttrig()` checked that the software trigger number matched this `start_arg` value. The backwards compatibility issue is that the internal trigger number now has to match `start_arg` when `start_src` is `TRIG_EXT` when it previously had to be 0. Fix the backwards compatibility issue in `ni_ao_inttrig()` by always allowing software trigger number 0 when `start_src` is something other than `TRIG_INT`.

2016-09-07staging: comedi: comedi_test: fix timer race conditionsIan Abbott
[ commit 403fe7f34e3327ddac2e06a15e76a293d613381e upstream. Patch is cut down a bit from upstream patch, as upstream patch fixed parts that don't exist in this version. Also, some identifiers were renamed, so patch description has been edited accordingly -- Ian Abbott ] Commit 73e0e4dfed4c ("staging: comedi: comedi_test: fix timer lock-up") fixed a lock-up in the timer routine `waveform_ai_interrupt()` caused by commit 240512474424 ("staging: comedi: comedi_test: use comedi_handle_events()"). However, it introduced a race condition that can result in the timer routine misbehaving, such as accessing freed memory or dereferencing a NULL pointer. 73e0... changed the timer routine to do nothing unless a `WAVEFORM_AI_RUNNING` flag was set, and changed `waveform_ai_cancel()` to clear the flag and replace a call to `del_timer_sync()` with a call to `del_timer()`. `waveform_ai_cancel()` may be called from the timer routine itself (via `comedi_handle_events()`), or from `do_cancel()`. (`do_cancel()` is called as a result of a file operation (usually a `COMEDI_CANCEL` ioctl command, or a release), or during device removal.) When called from `do_cancel()`, the call to `waveform_ai_cancel()` is followed by a call to `do_become_nonbusy()`, which frees up stuff for the current asynchronous command under the assumption that it is now safe to do so. The race condition occurs when the timer routine `waveform_ai_interrupt()` checks the `WAVEFORM_AI_RUNNING` flag just before it is cleared by `waveform_ai_cancel()`, and is still running during the call to `do_become_nonbusy()`. In particular, it can lead to a NULL pointer dereference because `do_become_nonbusy()` frees `async->cmd.chanlist` and sets it to `NULL`, but `waveform_ai_interrupt()` dereferences it. Fix the race by calling `del_timer_sync()` instead of `del_timer()` in `waveform_ai_cancel()` when not in an interrupt context. The only time `waveform_ai_cancel()` is called in an interrupt context is when it is called from the timer routine itself, via `comedi_handle_events()`. There is no longer any need for the `WAVEFORM_AI_RUNNING` flag, so get rid of it.

[ Upstream commit c2e771b02792d222cbcd9617fe71482a64f52647 ] Like the NFP6000, the NFP4000 as an erratum where reading/writing to PCI config space addresses above 0x600 can cause the NFP to generate PCIe completion timeouts.

2016-08-31clocksource/drivers/sun4i: Clear interrupts after stopping timer in probe ↵Chen-Yu Tsai
function [ Upstream commit b53e7d000d9e6e9fd2c6eb6b82d2783c67fd599e ] The bootloader (U-boot) sometimes uses this timer for various delays. It uses it as a ongoing counter, and does comparisons on the current counter value. The timer counter is never stopped. In some cases when the user interacts with the bootloader, or lets it idle for some time before loading Linux, the timer may expire, and an interrupt will be pending. This results in an unexpected interrupt when the timer interrupt is enabled by the kernel, at which point the event_handler isn't set yet. This results in a NULL pointer dereference exception, panic, and no way to reboot. Clear any pending interrupts after we stop the timer in the probe function to avoid this.

[ Upstream commit 33be126510974e2eb9679f1ca9bca4f67ee4c4c7 ] Fix "Command completion event does not match command" errors by always handling the command ring stopped events. The command ring stopped event is generated as a result of aborting or stopping the command ring with a register write. It is not caused by a command in the command queue, and thus won't have a matching command in the comman list. Solve it by handling the command ring stopped event before checking for a matching command. In most command time out cases we abort the command ring, and get a command ring stopped event. The events command pointer will point at the current command ring dequeue, which in most cases matches the timed out command in the command list, and no error messages are seen. If we instead get a command aborted event before the command ring stopped event, the abort event will increse the command ring dequeue pointer, and the following command ring stopped events command pointer will point at the next, not yet queued command.
