Bug#860269: libkf5bluezqt6: kded5 leaks file descriptor to child processes, /dev/rfkill should be opened with CLOEXEC
Package: libkf5bluezqt6
Version: 5.28.0-1
Severity: normal
I have noticed lvm tools complaining about leaked file descriptors when
they are started from a shell in a kde konsole. One of the file
descriptors is /dev/rfkill , which is likely opened by
/usr/lib/x86_64-linux-gnu/libKF5BluezQt.so.5.28.0 (at least that's the
only lib in kded5's /proc/../maps file that contains the string rfkill.
libkf5bluezqt6 should open the file with O_CLOEXEC to avoid leaks.
$ LANG=C ls -l /proc/$$/fd
total 0
