That commit added a struct blk_mq_tag_set to struct floppy_state and initialized it with a blk_mq_init_sq_queue() call. Unfortunately, there is a memset() in swim3_add_device() that subsequently clears the floppy_state struct. That means fs->tag_set->ops is a NULL pointer, and it gets dereferenced by blk_mq_free_rqs() which gets called in the request_irq() error path. Move the memset() to fix this bug. BTW, the request_irq() failure for the left mediabay floppy (fd1) is not a regression. I don't know why it happens. The right media bay floppy (fd0) works fine however.

2018-12-31block/swim3: Fix -EBUSY error when re-opening device after unmountFinn Thain1-1/+5
When the block device is opened with FMODE_EXCL, ref_count is set to -1. This value doesn't get reset when the device is closed which means the device cannot be opened again. Fix this by checking for refcount <= 0 in the release method.

2018-12-31r8169: fix WoL device wakeup enableHeiner Kallweit1-2/+2
In rtl8169_runtime_resume() we configure WoL but don't set the device to wakeup-enabled. This prevents PME generation once the cable is re-plugged.

2018-12-31net/wan: fix a double free in x25_asy_open_tty()Cong Wang1-0/+2
When x25_asy_open() fails, it already cleans up by itself, so its caller doesn't need to free the memory again. It seems we still have to call x25_asy_free() to clear the SLF_INUSE bit, so just set these pointers to NULL after kfree().

2018-12-31rtc: nvmem: fix possible use after freeAlexandre Belloni1-4/+5
In cas of probe failure, devres may free the memory allocated for rtc->nvram before devm_rtc_release_device() is called. This leads to rtc_nvram_unregister using it after being freed which may lead to a crash.

2018-12-29gdrom: fix a memory leak bugWenwen Wang1-0/+1
In probe_gdrom(), the buffer pointed by 'gd.cd_info' is allocated through kzalloc() and is used to hold the information of the gdrom device. To register and unregister the device, the pointer 'gd.cd_info' is passed to the functions register_cdrom() and unregister_cdrom(), respectively. However, this buffer is not freed after it is used, which can cause a memory leak bug. This patch simply frees the buffer 'gd.cd_info' in exit_gdrom() to fix the above issue.

HFCPCI_l1hw() In drivers/isdn/hisax/hfc_pci.c, the functions hfcpci_interrupt() and HFCPCI_l1hw() may be concurrently executed. HFCPCI_l1hw() line 1173: if (!cs->tx_skb) hfcpci_interrupt() line 942: spin_lock_irqsave(); line 1066: dev_kfree_skb_irq(cs->tx_skb); Thus, a possible concurrency use-after-free bug may occur in HFCPCI_l1hw(). To fix these bugs, the calls to spin_lock_irqsave() and spin_unlock_irqrestore() are added in HFCPCI_l1hw(), to protect the access to cs->tx_skb.

Binder now has one to handle the use of it in containerized systems. This was discussed at the Plumbers conference a few months ago and knocked into mergable shape very fast by Christian Brauner. Who also has signed up to be another binder maintainer, showing a distinct lack of good judgement :) - binder updates and fixes - mei driver updates - fpga driver updates and additions - thunderbolt driver updates - soundwire driver updates - extcon driver updates - nvmem driver updates - hyper-v driver updates - coresight driver updates - pvpanic driver additions and reworking for more device support - lp driver updates.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.21 kernel series. Core changes: - Some core changes are already in outside of this pull request as they came through the regulator tree, most notably devm_gpiod_unhinge() that removes devres refcount management from a GPIO descriptor. This is needed in subsystems such as regulators where the regulator core need to take over the reference counting and lifecycle management for a GPIO descriptor. - We dropped devm_gpiochip_remove() and devm_gpio_chip_match() as nothing needs it. We can bring it back if need be. - Add a global TODO so people see where we are going. This helps setting the direction now that we are two GPIO maintainers. - Handle the MMC CD/WP properties in the device tree core. (The bulk of patches activating this code is already merged through the MMC/SD tree.) - Augment gpiochip_request_own_desc() to pass a flag so we as gpiochips can request lines as active low or open drain etc even from ourselves. New drivers: - New driver for Cadence GPIO blocks. - New driver for Atmel SAMA5D2 PIOBU GPIO lines. Driver improvements: - A major refactoring of the PCA953x driver - this driver has been around for ages, and is now modernized to reduce code duplication that has stacked up and is using regmap to read write and cache registers. - Intel drivers are now maintained in a separate tree and start with a round of cleanups and unifications" * tag 'gpio-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (99 commits) gpio: sama5d2-piobu: Depend on OF_GPIO gpio: Add Cadence GPIO driver dt-bindings: gpio: Add bindings for Cadence GPIO gpiolib-acpi: remove unused variable 'err', cleans up build warning gpio: mxs: read pin level directly instead of using .get gpio: aspeed: remove duplicated statement gpio: add driver for SAMA5D2 PIOBU pins dt-bindings: arm: atmel: describe SECUMOD usage as a GPIO controller gpio/mmc/of: Respect polarity in the device tree dt-bindings: gpio: rcar: Add r8a774c0 (RZ/G2E) support memory: omap-gpmc: Get the header of the enum ARM: omap1: Fix new user of gpiochip_request_own_desc() gpio: pca953x: Add regmap dependency for PCA953x driver gpio: raspberrypi-exp: decrease refcount on firmware dt node gpiolib: Fix return value of gpio_to_desc() stub if !GPIOLIB gpio: pca953x: Restore registers after suspend/resume cycle gpio: pca953x: Zap single use of pca953x_read_single() gpio: pca953x: Zap ad-hoc reg_output cache gpio: pca953x: Zap ad-hoc reg_direction cache gpio: pca953x: Perform basic regmap conversion ...

2018-12-29Input: atmel_mxt_ts - don't try to free unallocated kernel memorySanjeev Chugh1-2/+2
