One division by zero fix in a specific driver and one core workaround for bad userspace behaviour from systemd regarding uevents. IMHO this can be considered to be a userspace bug, but the debug messages are useless anyways - cpcap-battery: fix a division by zero - core: fix systemd issue due to log messages produced by uevent" * tag 'for-v5.1-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply: power: supply: sysfs: prevent endless uevent loop with CONFIG_POWER_SUPPLY_DEBUG power: supply: cpcap-battery: Fix division by zero
| * power: supply: sysfs: prevent endless uevent loop with CONFIG_POWER_SUPPLY_DEBUGAndrey Smirnov2019-04-261-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a similar endless event loop as was done in commit 8dcf32175b4e ("i2c: prevent endless uevent loop with CONFIG_I2C_DEBUG_CORE"): The culprit is the dev_dbg printk in the i2c uevent handler. If this is activated (for instance by CONFIG_I2C_DEBUG_CORE) it results in an endless loop with systemd-journald. This happens if user-space scans the system log and reads the uevent file to get information about a newly created device, which seems fair use to me. Unfortunately reading the "uevent" file uses the same function that runs for creating the uevent for a new device, generating the next syslog entry Both CONFIG_I2C_DEBUG_CORE and CONFIG_POWER_SUPPLY_DEBUG were reported in https://bugs.freedesktop.org/show_bug.cgi?id=76886 but only former seems to have been fixed. Drop debug prints as it was done in I2C subsystem to resolve the issue.

WARNING: 'SPDX-License-Identifier: GPL' is not supported in LICENSES/... #19: FILE: drivers/power/supply/goldfish_battery.c:1: +// SPDX-License-Identifier: GPL Which is absolutely hillarious as the commit introducing this wreckage says in the changelog: There was a checkpatch complain: "Missing or malformed SPDX-License-Identifier tag". Oh well. Replacing a checkpatch warning by a different checkpatch warning is a really useful exercise. Use the proper GPL-2.0 identifier which is what the boiler plate in the file had originally.

| | | | | | | | | | | | | | | The work which is scheduled on a POR boot is potentially left pending or running until after the device module is removed, which could result in a use-after-free. Fix by registering a cancel/sync callback, which gets executed as part of standard resource unwinding. This issue was detected with the help of Coccinelle.

| | | | | | | | | | | | | | | | In remove(), use cancel_delayed_work_sync() to cancel the delayed work. Otherwise there's a chance that this work will continue to run until after the device has been removed. While we're here, fix the deallocation order in remove(), to correspond to the inverse of the probe() allocation order. This guarantees that any remaining work can run to completion with all driver structures still intact. This issue was detected with the help of Coccinelle.
