commit 478913fd upstream. The driver mismatched 'num_supplicants' with 'num_supplies' of power_supply structure. It provided list of supplicants (power_supply.supplied_to) but did not set the number of supplicants. Instead it set the num_supplies which is used when iterating over number of supplies (power_supply.supplied_from). As a result the list of supplicants was ignored by core because its size was 0.

commit 62cf983a upstream. Commit 0dcaa249 ("sdhci-pxav3: Fix runtime PM initialization") tries to fix one hang issue caused by calling sdhci_add_host() on a suspended device. The fix enables the clock twice, once by clk_prepare_enable() and another by pm_runtime_get_sync(), meaning that the clock will never be gated at runtime PM suspend. I observed the power consumption regression on Marvell BG2Q SoCs. In fact, the fix is not correct. There still be a very small window during which a runtime suspend might somehow occur after pm_runtime_enable() but before pm_runtime_get_sync(). This patch fixes all of the two problems by just incrementing the usage counter before pm_runtime_enable(). It also adjust the order of disabling runtime pm and storing the usage count in the error path to handle clock gating properly. Signed-off-by:

commit 1ba3b0b6 upstream. When sending data in tpm_stm_i2c_send, each loop iteration send buf. Send buf + i instead as the goal of this for loop is to send a number of byte from buf that fit in burstcnt. Once those byte are sent, we are supposed to send the next ones. The driver was working because the burstcount value returns always the maximum size for a TPM command or response. (0x800 for a command and 0x400 for a response). Reviewed-by:

commit 84eb186b upstream. There was an oops in tpm_ibmvtpm_get_desired_dma, which caused kernel panic during boot when vTPM is enabled in Power partition configured in AMS mode. vio_bus_probe calls vio_cmo_bus_probe which calls tpm_ibmvtpm_get_desired_dma to get the size needed for DMA allocation. The problem is, vio_cmo_bus_probe is called before calling probe, which for vtpm is tpm_ibmvtpm_probe and it's this function that initializes and sets up vtpm's CRQ and gets required data values. Therefore, since this has not yet been done, NULL is returned in attempt to get the size for DMA allocation. We added a NULL check. In addition, a default buffer size will be set when NULL is returned. Signed-off-by:

commit 448e9c55 upstream. Some machines, such as the Acer C720 and Toshiba CB35, have TPMs that do not send IRQs while also having an ACPI TPM entry indicating that they will be sent. These machines freeze on resume while the tpm_tis module waits for an IRQ, eventually timing out. When in interrupt mode, the tpm_tis module should receive an IRQ during module init. Fall back to polling mode if none is received when expected. Signed-off-by:

commit 28423ad2 upstream. While debugging an issue with excessive softirq usage, I encountered the following note in commit 3e339b5d ("softirq: Use hotplug thread infrastructure"): [ paulmck: Call rcu_note_context_switch() with interrupts enabled. ] ...but despite this note, the patch still calls RCU with IRQs disabled. This seemingly innocuous change caused a significant regression in softirq CPU usage on the sending side of a large TCP transfer (~1 GB/s): when introducing 0.01% packet loss, the softirq usage would jump to around 25%, spiking as high as 50%. Before the change, the usage would never exceed 5%. Moving the call to rcu_note_context_switch() after the cond_sched() call, as it was originally before the hotplug patch, completely eliminated this problem. Signed-off-by:

commit 6fbb9bdf upstream. -EDEFER error wasn't handle properly by atmel_serial_probe(). As an example, when atmel_serial_probe() is called for the first time, we pass the test_and_set_bit() test to check whether the port has already been initalized. Then we call atmel_init_port(), which may return -EDEFER, possibly returned before by clk_get(). Consequently atmel_serial_probe() used to return this error code WITHOUT clearing the port bit in the "atmel_ports_in_use" mask. When atmel_serial_probe() was called for the second time, it used to fail on the test_and_set_bit() function then returning -EBUSY. When atmel_serial_probe() fails, this patch make it clear the port bit in the "atmel_ports_in_use" mask, if needed, before returning the error code. Signed-off-by:

commit d4f64187 upstream. atmel_serial_probe() calls atmel_init_port(). In turn, atmel_init_port() calls clk_disable_unprepare() to disable the peripheral clock before returning. Later atmel_serial_probe() accesses some I/O registers such as the Mode and Control registers for RS485 support then the Name and Version registers, through a call to atmel_get_ip_name(), but at that moment the peripheral clock was still disabled.

commit 5efd2ea8 upstream. the following error pops up during "testusb -a -t 10" | musb-hdrc musb-hdrc.1.auto: dma_pool_free buffer-128, f134e000/be842000 (bad dma) hcd_buffer_create() creates a few buffers, the smallest has 32 bytes of size. ARCH_KMALLOC_MINALIGN is set to 64 bytes. This combo results in hcd_buffer_alloc() returning memory which is 32 bytes aligned and it might by identified by buffer_offset() as another buffer. This means the buffer which is on a 32 byte boundary will not get freed, instead it tries to free another buffer with the error message. This patch fixes the issue by creating the smallest DMA buffer with the size of ARCH_KMALLOC_MINALIGN (or 32 in case ARCH_KMALLOC_MINALIGN is smaller). This might be 32, 64 or even 128 bytes. The next three pools will have the size 128, 512 and 2048. In case the smallest pool is 128 bytes then we have only three pools instead of four (and zero the first entry in the array). The last pool size is always 2048 bytes which is the assumed PAGE_SIZE / 2 of 4096. I doubt it makes sense to continue using PAGE_SIZE / 2 where we would end up with 8KiB buffer in case we have 16KiB pages. Instead I think it makes sense to have a common size(s) and extend them if there is need to. There is a BUILD_BUG_ON() now in case someone has a minalign of more than 128 bytes. Signed-off-by:

commit 145b3fe5 upstream. Some implementations of modprobe fail to load the driver for a PCI device automatically because the "interface" part of the modalias from the kernel is lowercase, and the modalias from file2alias is uppercase. The "interface" is the low-order byte of the Class Code, defined in PCI r3.0, Appendix D. Most interface types defined in the spec do not use alpha characters, so they won't be affected. For example, 00h, 01h, 10h, 20h, etc. are unaffected. Print the "interface" byte of the Class Code in uppercase hex, as we already do for the Vendor ID, Device ID, Class, etc. Commit 89ec3dcf ("PCI: Generate uppercase hex for modalias interface class") fixed only half of the problem. Some udev implementations rely on the uevent file and not the modalias file.

commit 6ce901eb upstream. On an PC-101/103/104 keyboard (American layout) the 'Enter' key and its neighbours look like this: +---+ +---+ +-------+ | 1 | | 2 | | 5 | +---+ +---+ +-------+ +---+ +-----------+ | 3 | | 4 | +---+ +-----------+ On a PC-102/105 keyboard (European layout) it looks like this: +---+ +---+ +-------+ | 1 | | 2 | | | +---+ +---+ +-+ 4 | +---+ +---+ | | | 3 | | 5 | | | +---+ +---+ +-----+ (Note that the number of keys is the same, but key '5' is moved down and the shape of key '4' is changed. Keys '1' to '3' are exactly the same.) The keys 1-4 report the same scan-code in HID in both layouts, even though the keysym they produce is usually different depending on the XKB-keymap used by user-space. However, key '5' (US 'backslash'/'pipe') reports 0x31 for the upper layout and 0x32 for the lower layout, as defined by the HID spec. This is highly confusing as the linux-input API uses a single keycode for both. So far, this was never a problem as there never has been a keyboard with both of those keys present at the same time. It would have to look something like this: +---+ +---+ +-------+ | 1 | | 2 | | x31 | +---+ +---+ +-------+ +---+ +---+ +-----+ | 3 | |x32| | 4 | +---+ +---+ +-----+ HID can represent such a keyboard, but the linux-input API cannot. Furthermore, any user-space mapping would be confused by this and, luckily, no-one ever produced such hardware. Now, the HID input layer fixed this mess by mapping both 0x31 and 0x32 to the same keycode (KEY_BACKSLASH==0x2b). As only one of both physical keys is present on a hardware, this works just fine. Lets introduce hardware-vendors into this: ------------------------------------------ Unfortunately, it seems way to expensive to produce a different device for American and European layouts. Therefore, hardware-vendors put both keys, (0x31 and 0x32) on the same keyboard, but only one of them is hooked up to the physical button, the other one is 'dead'. This means, they can use the same hardware, with a different button-layout and automatically produce the correct HID events for American *and* European layouts. This is unproblematic for normal keyboards, as the 'dead' key will never report any KEY-DOWN events. But RollOver keyboards send the whole matrix on each key-event, allowing n-key roll-over mode. This means, we get a 0x31 and 0x32 event on each key-press. One of them will always be 0, the other reports the real state. As we map both to the same keycode, we will get spurious key-events, even though the real key-state never changed. The easiest way would be to blacklist 'dead' keys and never handle those. We could simply read the 'country' tag of USB devices and blacklist either key according to the layout. But... hardware vendors... want the same device for all countries and thus many of them set 'country' to 0 for all devices. Meh.. So we have to deal with this properly. As we cannot know which of the keys is 'dead', we either need a heuristic and track those keys, or we simply make use of our value-tracking for HID fields. We simply ignore HID events for absolute data if the data didn't change. As HID tracks events on the HID level, we haven't done the keycode translation, yet. Therefore, the 'dead' key is tracked independently of the real key, therefore, any events on it will be ignored. This patch simply discards any HID events for absolute data if it didn't change compared to the last report. We need to ignore relative and buffered-byte reports for obvious reasons. But those cannot be affected by this bug, so we're fine. Preferably, we'd do this filtering on the HID-core level. But this might break a lot of custom drivers, if they do not follow the HID specs. Therefore, we do this late in hid-input just before we inject it into the input layer (which does the exact same filtering, but on the keycode level). If this turns out to break some devices, we might have to limit filtering to EV_KEY events. But lets try to do the Right Thing first, and properly filter any absolute data that didn't change. This patch is tagged for 'stable' as it fixes a lot of n-key RollOver hardware. We might wanna wait with backporting for a while, before we know it doesn't break anything else, though. Reported-by:

commit 0418ca60 upstream. The lockdep splat addressed in a previous commit revealed that at least one message in em28xx-input.c was missing a new line: em28178 #0: Closing input extensionINFO: trying to register non-static key. Further inspection shows several other messages also miss a new line. These will be fixed in a subsequent patch. Fixes: aa929ad7 ("[media] em28xx: print a message at disconnect") Signed-off-by:

commit bbfebeea upstream. Removing the em28xx-rc module results in the following lockdep splat, which is caused by trying to call cancel_delayed_work_sync() on an uninitialised delayed work. Fix this by ensuring we always initialise the work. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

commit a1eb03f5 upstream. The reason we defer kfree until release function is because it's a general rule for kobjects: kfree of the reference counter itself is only legal in the release function. Previous patch didn't make this clear, document this in code. Signed-off-by:

commit 63bd62a0 upstream. A struct device which has just been unregistered can live on past the point at which a driver decides to drop it's initial reference to the kobject gained on allocation. This implies that when releasing a virtio device, we can't free a struct virtio_device until the underlying struct device has been released, which might not happen immediately on device_unregister(). Unfortunately, this is exactly what virtio pci does: it has an empty release callback, and frees memory immediately after unregistering the device. This causes an easy to reproduce crash if CONFIG_DEBUG_KOBJECT_RELEASE it enabled. To fix, free the memory only once we know the device is gone in the release callback. Signed-off-by:

commit 6a2a2b3a upstream. Linux manpage for recvmsg and sendmsg calls does not explicitly mention setting msg_namelen to 0 when msg_name passed set as NULL. When developers don't set msg_namelen member in msghdr, it might contain garbage value which will fail the validation check and sendmsg and recvmsg calls from kernel will return EINVAL. This will break old binaries and any code for which there is no access to source code. To fix this, we set msg_namelen to 0 when msg_name is passed as NULL from userland. Signed-off-by:
