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 lrwx------ 1 stf stf 64 Apr 13 21:01 0 -> /dev/pts/3 lrwx------ 1 stf stf 64 Apr 13 21:01 1 -> /dev/pts/3 lrwx------ 1 stf stf 64 Apr 13 21:01 2 -> /dev/pts/3 lrwx------ 1 stf stf 64 Apr 13 21:01 255 -> /dev/pts/3 lr-x------ 1 stf stf 64 Apr 13 21:01 31 -> /dev/rfkill lrwx------ 1 stf stf 64 Apr 13 21:01 37 -> socket:[28435] -- System Information: Debian Release: 9.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: armhf, i386 Kernel: Linux 4.9.0-2-amd64 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libkf5bluezqt6 depends on: ii libc6 2.24-10 ii libkf5bluezqt-data 5.28.0-1 ii libqt5core5a 5.7.1+dfsg-3+b1 ii libqt5dbus5 5.7.1+dfsg-3+b1 ii libqt5network5 5.7.1+dfsg-3+b1 ii libstdc++6 6.3.0-12 libkf5bluezqt6 recommends no packages. libkf5bluezqt6 suggests no packages. -- no debconf information
