Bug description:
[Impact]
* fwupd (used in Xenial) does not close USB device nodes when it fails to
process the
devices.
* The orphan (un-closed) device node will be kept until fwupd ends
* The behavior will avoid the system to set the USB device as
idle/suspend then the system cannot enter some power-saving mode (eg.
S0ix)
[Test Case]
* make sure fwupd is not running by executing 'fwupdmgr get-devices'
It will show devices information.
* list the fds opened by fwupd
$ sudo ls -l /proc/$(pgrep fwupd)/fd | grep usb
If a system is not affected, it will output nothing.
If the result shows one or more strings like /dev/bus/usb/[BUS]/[DEV]
(BUS and DEV are numeric variables), that means the issue is existing.
[Regression Potential]
* The fix only closes file descriptors of USB devices when errors
happen and should not have regression there.
[Original description]
In fwupd, a few of USB devices are not closed when there are some failures
of
operations. This issue will cause fwupd has some orphan USB nodes inside
during fwupd is
running. A orphan USB node might introduce memory leak and block some
runtime power
features as well.
I proposed a upstream PR, and also put the link here.
