Package: procps Version: 2:3.3.16-5 Severity: normal File: /sbin/sysctl The man page gives this example command:
/sbin/sysctl --system --pattern '^net.ipv6' However, if you run a command like this, the --pattern is ignored, and all parameters are applied, not just the ones that match the --pattern (notice that the fs. parameters are not skipped here, even though they do not match the --pattern that I specified): $ sudo sysctl --system --pattern '^kernel\.' * Applying /usr/lib/sysctl.d/30-tracker.conf ... fs.inotify.max_user_watches = 65536 * Applying /usr/lib/sysctl.d/50-coredump.conf ... kernel.core_pattern = |/lib/systemd/systemd-coredump %P %u %g %s %t 9223372036854775808 %h kernel.core_pipe_limit = 16 fs.suid_dumpable = 2 * Applying /usr/lib/sysctl.d/50-pid-max.conf ... kernel.pid_max = 4194304 This can be worked around by making sure --system is the last argument (notice that the fs. parameters are correctly skipped here): $ sudo sysctl --pattern '^kernel\.' --system * Applying /usr/lib/sysctl.d/30-tracker.conf ... * Applying /usr/lib/sysctl.d/50-coredump.conf ... kernel.core_pattern = |/lib/systemd/systemd-coredump %P %u %g %s %t 9223372036854775808 %h kernel.core_pipe_limit = 16 * Applying /usr/lib/sysctl.d/50-pid-max.conf ... kernel.pid_max = 4194304 The problem appears to be that all other options just set a variable, but SYSTEM_OPTION does an early-return with "return PreloadSystem()", ignoring the rest of the command-line. I think the solution would be something like this: bool AllSystemFiles = false; ... case SYSTEM_OPTION: IgnoreError = true; AllSystemFiles = true; break; ... if (preloadFileOpt) { ... } else if (AllSystemFiles) { return PreloadSystem(); } -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-debug'), (500, 'buildd-unstable'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (1, 'experimental-debug'), (1, 'buildd-experimental'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-trunk-amd64 (SMP w/8 CPU threads) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages procps depends on: ii init-system-helpers 1.60 ii libc6 2.31-6 ii libncurses6 6.2+20201114-2 ii libncursesw6 6.2+20201114-2 ii libprocps8 2:3.3.16-5 ii libtinfo6 6.2+20201114-2 ii lsb-base 11.1.0 Versions of packages procps recommends: ii psmisc 23.3-1 procps suggests no packages. -- no debconf information
