2015-12-09KVM: s390: enable SIMD only when no VCPUs were createdDavid Hildenbrand
commit 5967c17b118a2bd1dd1d554cc4eee16233e52bec upstream. We should never allow to enable/disable any facilities for the guest when other VCPUs were already created. kvm_arch_vcpu_(load|put) relies on SIMD not changing during runtime. If somebody would create and run VCPUs and then decides to enable SIMD, undefined behaviour could be possible (e.g. vector save area not being set up).

2015-12-09xen/events: Always allocate legacy interrupts on PV guestsBoris Ostrovsky
commit b4ff8389ed14b849354b59ce9b360bdefcdbf99c upstream. After commit 8c058b0b9c34 ("x86/irq: Probe for PIC presence before allocating descs for legacy IRQs") early_irq_init() will no longer preallocate descriptors for legacy interrupts if PIC does not exist, which is the case for Xen PV guests. Therefore we may need to allocate those descriptors ourselves.

The recently introduced lnet_peer_set_alive() function uses get_seconds() to read the current time into a shared variable, but all other uses of that variable compare it to jiffies values.

2015-12-09xhci: Workaround to get Intel xHCI reset working more reliablyRajmohan Mani
commit a5964396190d0c40dd549c23848c282fffa5d1f2 upstream. Existing Intel xHCI controllers require a delay of 1 mS, after setting the CMD_RESET bit in command register, before accessing any HC registers. This allows the HC to complete the reset operation and be ready for HC register access. Without this delay, the subsequent HC register access, may result in a system hang, very rarely. Verified CherryView / Braswell platforms go through over 5000 warm reboot cycles (which was not possible without this patch), without any xHCI reset hang.

2015-12-09ALSA: usb-audio: work around CH345 input SysEx corruptionClemens Ladisch
commit a91e627e3f0ed820b11d86cdc04df38f65f33a70 upstream. One of the many faults of the QinHeng CH345 USB MIDI interface chip is that it does not handle received SysEx messages correctly -- every second event packet has a wrong code index number, which is the one from the last seen message, instead of 4. For example, the two messages "FE F0 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E F7" result in the following event packets: correct: CH345: 0F FE 00 00 0F FE 00 00 04 F0 01 02 04 F0 01 02 04 03 04 05 0F 03 04 05 04 06 07 08 04 06 07 08 04 09 0A 0B 0F 09 0A 0B 04 0C 0D 0E 04 0C 0D 0E 05 F7 00 00 05 F7 00 00 A class-compliant driver must interpret an event packet with CIN 15 as having a single data byte, so the other two bytes would be ignored. The message received by the host would then be missing two bytes out of six; in this example, "F0 01 02 03 06 07 08 09 0C 0D 0E F7". These corrupted SysEx event packages contain only data bytes, while the CH345 uses event packets with a correct CIN value only for messages with a status byte, so it is possible to distinguish between these two cases by checking for the presence of this status byte. (Other bugs in the CH345's input handling, such as the corruption resulting from running status, cannot be worked around.)

2015-12-09ALSA: usb-audio: prevent CH345 multiport output SysEx corruptionClemens Ladisch
commit 1ca8b201309d842642f221db7f02f71c0af5be2d upstream. The CH345 USB MIDI chip has two output ports. However, they are multiplexed through one pin, and the number of ports cannot be reduced even for hardware that implements only one connector, so for those devices, data sent to either port ends up on the same hardware output. This becomes a problem when both ports are used at the same time, as longer MIDI commands (such as SysEx messages) are likely to be interrupted by messages from the other port, and thus to get lost. It would not be possible for the driver to detect how many ports the device actually has, except that in practice, _all_ devices built with the CH345 have only one port. So we can just ignore the device's descriptors, and hardcode one output port.

commit 705e63d2b29c8bbf091119084544d353bda70393 upstream. There is a bit of a mess in the order of arguments to the ulpi write callback.

The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users.

commit 59536da34513c594af2a6fd35ba65ea45b6960a1 upstream. The DEVICE_HWI type was added under the faulty assumption that Huawei devices based on Qualcomm chipsets and firmware use the static USB interface numbering known from Gobi devices. But this model does not apply to Huawei devices like the HP branded lt4112 (Huawei me906e). Huawei firmwares will dynamically assign interface numbers. Functions are renumbered when the firmware is reconfigured. Fix by changing the DEVICE_HWI type to use a simplified version of Huawei's subclass + protocol scheme: Blacklisting known network interface combinations and assuming the rest are serial.

commit 690fb3718a70c66004342f6f5e2e8a5f95b977db upstream. This patch allows the dwc3 driver to run on the new Synopsys USB 3.1 IP core, albeit in USB 3.0 mode only. The Synopsys USB 3.1 IP (DWC_usb31) retains mostly the same register interface and programming model as the existing USB 3.0 controller IP (DWC_usb3). However the GSNPSID and version numbers are different. Add checking for the new ID to pass driver probe. Also, since the DWC_usb31 version number is lower in value than the full GSNPSID of the DWC_usb3 IP, we set the high bit to identify DWC_usb31 and to ensure the values are higher. Finally, add a documentation note about the revision numbering scheme. Any future revision checks (for STARS, workarounds, and new features) should take into consideration how it applies to both the 3.1/3.0 IP.

2015-12-09usb: dwc3: gadget: let us set lower max_speedBen McCauley
commit b9e51b2b1fda19143f48d182ed7a2943f21e1ae4 upstream. In some SoCs, dwc3 is implemented as a USB2.0 only core, meaning that it can't ever achieve SuperSpeed. Currect driver always sets gadget.max_speed to USB_SPEED_SUPER unconditionally. This can causes issues to some Host stacks where the host will issue a GetBOS() request and we will reply with a BOS containing Superspeed Capability Descriptor. At least Windows seems to be upset by this fact and prints a warning that we should connect $this device to another port.

commit d134c48d889ddceadf4c990e6f3df16b816ed5d4 upstream. Following changes that appeared in lk 4.0.0, the gadget udc driver for some ARM based Atmel SoCs (e.g. at91sam9x5 and sama5d3 families) incorrectly deduced full-speed USB link speed even when the hardware had negotiated a high-speed link. The fix is to make sure that the UDPHS Interrupt Enable Register value does not mask the SPEED bit in the Interrupt Status Register. For a mass storage gadget this problem lead to failures when the host had a USB 3 port with the xhci_hcd driver. If the host was a USB 2 port using the ehci_hcd driver then the mass storage gadget worked (but probably at a lower speed than it should have).

commit c5c2c393468576bad6d10b2b5fefff8cd25df3f4 upstream. We seemed to have missed a few corner cases in commit f6c137ff00a4 ("KVM: s390: randomize sca address"). The SCA has a maximum size of 2112 bytes. By setting the sca_offset to some unlucky numbers, we exceed the page. 0x7c0 (1984) -> Fits exactly 0x7d0 (2000) -> 16 bytes out 0x7e0 (2016) -> 32 bytes out 0x7f0 (2032) -> 48 bytes out One VCPU entry is 32 bytes long. For the last two cases, we actually write data to the other page. 1. The address of the VCPU. 2. Injection/delivery/clearing of SIGP externall calls via SIGP IF. Especially the 2. happens regularly. So this could produce two problems: 1. The guest losing/getting external calls. 2. Random memory overwrites in the host. So this problem happens on every 127 + 128 created VM with 64 VCPUs.

commit cb083816ab5ac3d10a9417527f07fc5962cc3808 upstream. A kernel built with DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA doesn't have .text aligned to a page boundary, though fixup_executable works at page-granularity thanks to its use of create_mapping. If .text is not page-aligned, the first page it exists in may be marked non-executable, leading to failures when an attempt is made to execute code in said page. This patch upgrades ALIGN_DEBUG_RO and ALIGN_DEBUG_RO_MIN to force page alignment for DEBUG_RO_DATA && !CONFIG_DEBUG_ALIGN_RODATA kernels, ensuring that all sections with specific RWX permission requirements are mapped with the correct permissions.

commit 7cecd9ab80f43972c056dc068338f7bcc407b71c upstream. According to SJA1000 data sheet error-warning (EI) interrupt is not cleared by setting the controller in to reset-mode. Then if we have the following case: - system is suspended (echo mem > /sys/power/state) and SJA1000 is left in operating state - A bus error condition occurs which activates EI interrupt, system is still suspended which means EI interrupt will be not be handled nor cleared. If the above two events occur, on resume there is no way to return the SJA1000 to operating state, except to cycle power to it. By simply reading the IR register on start we will clear any previous conditions that could be present.

2015-12-09Bluetooth: Fix removing connection parameters when unpairingJohan Hedberg
commit a6ad2a6b9cc1d9d791aee5462cfb8528f366f1d4 upstream. The commit 89cbb0638e9b7 introduced support for deferred connection parameter removal when unpairing by removing them only once an existing connection gets disconnected. However, it failed to address the scenario when we're *not* connected and do an unpair operation. What makes things worse is that most user space BlueZ versions will first issue a disconnect request and only then unpair, meaning the buggy code will be triggered every time. This effectively causes the kernel to resume scanning and reconnect to a device for which we've removed all keys and GATT database information. This patch fixes the issue by adding the missing call to the hci_conn_params_del() function to a branch which handles the case of no existing connection.

2015-12-09Bluetooth: hidp: fix device disconnect on idle timeoutDavid Herrmann
commit 660f0fc07d21114549c1862e67e78b1cf0c90c29 upstream. The HIDP specs define an idle-timeout which automatically disconnects a device. This has always been implemented in the HIDP layer and forced a synchronous shutdown of the hidp-scheduler. This works just fine, but lacks a forced disconnect on the underlying l2cap channels. This has been broken since: commit 5205185d461d5902325e457ca80bd421127b7308 Author: David Herrmann <dh.herrmann@gmail.com> Date: Sat Apr 6 20:28:47 2013 +0200 Bluetooth: hidp: remove old session-management The old session-management always forced an l2cap error on the ctrl/intr channels when shutting down. The new session-management skips this, as we don't want to enforce channel policy on the caller. In other words, if user-space removes an HIDP device, the underlying channels (which are *owned* and *referenced* by user-space) are still left active. User-space needs to call shutdown(2) or close(2) to release them. Unfortunately, this does not work with idle-timeouts. There is no way to signal user-space that the HIDP layer has been stopped. The API simply does not support any event-passing except for poll(2). Hence, we restore old behavior and force EUNATCH on the sockets if the HIDP layer is disconnected due to idle-timeouts (behavior of explicit disconnects remains unmodified). User-space can still call getsockopt(..., SO_ERROR, ...) ..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can still be re-used (which nobody does so far, though). Therefore, the API still supports the new behavior, but with this patch it's also compatible to the old implicit channel shutdown.

There were several bugs here. 1) The done label was in the wrong place so we didn't copy any information out when there was no command given. 2) We were using PAGE_SIZE as the size of the buffer instead of "PAGE_SIZE - pos". 3) snprintf() returns the number of characters that would have been printed if there were enough space. If there was not enough space (and we had fixed the memory corruption bug #2) then it would result in an information leak when we do simple_read_from_buffer(). I've changed it to use scnprintf() instead. I also removed the initialization at the start of the function, because I thought it made the code a little more clear.

However, that patch did not consider a typical situation where twl6040 is built-in, and palmas-clk is a loadable module like we have in omap2plus_defconfig. If palmas-clk is not loaded before twl6040 probes, we will get a "clk32k is not handled" warning during booting. This means that any drivers relying on this clock will mysteriously fail, including omap5-uevm WLAN and audio. Note that for WLAN, we probably should also eventually get the clk32kgaudio for MMC3 directly as that's shared between audio and WLAN SDIO at least for omap5-uevm. It seems the WLAN chip cannot get it as otherwise MMC3 won't get properly probed.
