https://bugzilla.suse.com/show_bug.cgi?id=1226464 Bug ID: 1226464 Summary: AUDIT-0: aaa_base: sysctl.d/50-default.conf has new defaults Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Security Assignee: security-team@suse.de Reporter: kukuk@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- sysctl.d/50-default.conf in aaa_base has new defaults: Remove kernel.pid_max limit (bsc#1219038) kernel.pid_max is one of multiple mechanisms to restrict number of processes [1]. Its kernel default is scaled with nr_cpus but 1024 tasks/cpu cap is too much if they were all running and it is also too little when they are idle (memory being bottleneck). Bump the limit to maximum kernel-accepted value and defer to other mechanisms for tasks limit enforcing. (This way we converge to same config like upstream systemd [2] but we ship distro defaults together from this package.)
