Package: lttng-tools Version: 2.13.9-1+b1 Severity: normal Dear Maintainer,
the package contains a systemd service lttng-sessiond, which auto-starts and by that loads lttng kernel modules (e.g. lttng_kretprobes). This is problematic, as these are out-of-tree modules which taint the kernel. Also it does not work if the modules are not installed or cannot be loaded (e.g. due to secure boot / kernel lockdown). I hereby recommend to install that service but do not enable it. If a user wants to debug with lttng, it can be started on demand. Best regards, Felix Moessbauer Siemens AG -- System Information: Debian Release: trixie/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 6.12.10-amd64 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lttng-tools depends on: ii init-system-helpers 1.68 ii libc6 2.40-6 ii libkmod2 33+20240816-2 pn liblttng-ctl0t64 <none> ii liblttng-ust-common1t64 2.13.8-2+b1 ii liblttng-ust-ctl5t64 2.13.8-2+b1 ii libpopt0 1.19+dfsg-2 ii liburcu8t64 0.14.1-1 ii libxml2 2.12.7+dfsg+really2.9.14-0.2+b1 Versions of packages lttng-tools recommends: pn babeltrace2 <none> Versions of packages lttng-tools suggests: pn lttng-modules-dkms <none>
