The initializing of q->root_blkg is currently outside of queue lock and rcu, so the blkg may be destroied before the initializing, which may cause dangling/null references. On the other side, the destroys of blkg are protected by queue lock or rcu. Put the initializing inside the queue lock and rcu to make it safer.

As described in the comment of blkcg_activate_policy(), *Update of each blkg is protected by both queue and blkcg locks so that holding either lock and testing blkcg_policy_enabled() is always enough for dereferencing policy data.* with queue lock held, there is no need to hold blkcg lock in blkcg_deactivate_policy(). Similar case is in blkcg_activate_policy(), which has removed holding of blkcg lock in commit 4c55f4f9.

This cast is wrong. "cdi->capacity" is an int and "arg" is an unsigned long. The way the check is written now, if one of the high 32 bits is set then we could read outside the info->slots[] array.

Even if we don't have an IO context attached to a request, we still need to clear the priv[0..1] pointers, as they could be pointing to previously used bic/bfqq structures. If we don't do so, we'll either corrupt memory on dispatching a request, or cause an imbalance in counters. Inspired by a fix from Kees.

rq->gstate and rq->aborted_gstate both are zero before rqs are allocated. If we have a small timeout, when the timer fires, there could be rqs that are never allocated, and also there could be rq that has been allocated but not initialized and started. At the moment, the rq->gstate and rq->aborted_gstate both are 0, thus the blk_mq_terminate_expired will identify the rq is timed out and invoke .timeout early. For scsi, this will cause scsi_times_out to be invoked before the scsi_cmnd is not initialized, scsi_cmnd->device is still NULL at the moment, then we will get crash.

Reading to the end of a 720K disk results in an IO error instead of EOF because the block layer thinks the disk has 2880 sectors. (Partly this is a result of inverted logic of the ONEMEG_MEDIA bit that's now fixed.) Initialize the density and head count in swim_add_floppy() to agree with the device size passed to set_capacity() during drive probe. Call set_capacity() again upon device open, after refreshing the density and head count values.

The Sony drive status bits use active-low logic. The swim_readbit() function converts that to 'C' logic for readability. Hence, the sense of the names of the status bit macros should not be inverted. Mostly they are correct. However, the TWOMEG_DRIVE, MFM_MODE and TWOMEG_MEDIA macros have inverted sense (like MkLinux). Fix this inconsistency and make the following patches less confusing. The same problem affects swim3.c so fix that too. No functional change. The FDHD drive status bits are documented in sonydriv.cpp from MAME and in swimiii.h from MkLinux.

We ran into an issue with loop and btrfs, where btrfs would complain about checksum errors. It turns out that is because we don't handle short reads at all, we just zero fill the remainder. Worse than that, we don't handle the filling properly, which results in loop trying to advance a single bio by much more than its size, since it doesn't take chaining into account. Handle short reads appropriately, by simply retrying at the new correct offset. End the remainder of the request with EIO, if we get a 0 read.

When blk_queue_enter() waits for a queue to unfreeze, or unset the PREEMPT_ONLY flag, do not allow it to be interrupted by a signal. The PREEMPT_ONLY flag was introduced later in commit 3a0a5299 ("block, scsi: Make SCSI quiesce and resume work reliably"). Note the SCSI device is resumed asynchronously, i.e. after un-freezing userspace tasks. So that commit exposed the bug as a regression in v4.15. A mysterious SIGBUS (or -EIO) sometimes happened during the time the device was being resumed. Most frequently, there was no kernel log message, and we saw Xorg or Xwayland killed by SIGBUS.[1] [1] E.g. https://bugzilla.redhat.com/show_bug.cgi?id=1553979 Without this fix, I get an IO error in this test: # dd if=/dev/sda of=/dev/null iflag=direct & \ while killall -SIGUSR1 dd; do sleep 0.1; done & \ echo mem > /sys/power/state ; \ sleep 5; killall dd # stop after 5 seconds The interruptible wait was added to blk_queue_enter in commit 3ef28e83 ("block: generic request_queue reference counting"). Before then, the interruptible wait was only in blk-mq, but I don't think it could ever have been correct.

Pull clk updates from Stephen Boyd: "The large diff this time around is from the addition of a new clk driver for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well. Core: - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops - debugfs ops macroized to shave some lines of boilerplate code - Always calculate the phase instead of caching it in clk_get_phase() - More __must_check on bulk clk APIs New Drivers: - TI's Davinci family of SoCs - Intel's Stratix10 SoC - stm32mp157 SoC - Allwinner H6 CCU - Silicon Labs SI544 clock generator chip - Renesas R-Car M3-N and V3H SoCs - i.MX6SLL SoCs Removed Drivers: - ST-Ericsson AB8540/9540 Updates: - Mediatek MT2701 and MT7622 audsys support and MT2712 updates - STM32F469 DSI and STM32F769 sdmmc2 support - GPIO clks can sleep now - Spreadtrum SC9860 RTC clks - Nvidia Tegra MBIST workarounds and various minor fixes - Rockchip phase handling fixes and a memory leak plugged - Renesas drivers switch to readl/writel from clk_readl/clk_writel - Renesas gained CPU (Z/Z2) and watchdog support - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support - Qualcomm PM8921 PMIC XO buffers - Amlogic migrates to regmap APIs - TI Keystone clk latching support - Allwinner H3 and H5 video clk fixes - Broadcom BCM2835 PLLs needed another bit to enable - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix - i.MX6UL/ULL epdc_podf support - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (233 commits) clk: davinci: add a reset lookup table for psc0 clk: imx: add clock driver for imx6sll dt-bindings: imx: update clock doc for imx6sll clk: imx: add new gate/gate2 wrapper funtion clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux clk: cs2000: set pm_ops in hibernate-compatible way clk: bcm2835: De-assert/assert PLL reset signal when appropriate clk: imx7d: Move clks_init_on before any clock operations clk: imx7d: Correct ahb clk parent select clk: imx7d: Correct dram pll type clk: imx7d: Add USB clock information clk: socfpga: stratix10: add clock driver for Stratix10 platform dt-bindings: documentation: add clock bindings information for Stratix10 clk: ti: fix flag space conflict with clkctrl clocks clk: uniphier: add additional ethernet clock lines for Pro4 clk: uniphier: add SATA clock control support clk: uniphier: add PCIe clock control support clk: Add driver for the si544 clock generator chip clk: davinci: Remove redundant dev_err calls clk: uniphier: add ethernet clock control support for PXs3 ...

The test which ensures that the DMI type 1 structure is long enough to hold the UUID is off by one. It would fail if the structure is exactly 24 bytes long, while that's sufficient to hold the UUID. I don't expect this bug to cause problem in practice because all implementations I have seen had length 8, 25 or 27 bytes, in line with the SMBIOS specifications. But let's fix it still.
