(TasksMax= is the primary + setting that exposes the "pids" cgroup controller on systemd + and was introduced in the previous systemd release.) The + setting now defaults to 512, which means services that are + not explicitly configured otherwise will only be able to + create 512 processes or threads at maximum, from this + version on. Note that this means that thread- or + process-heavy services might need to be reconfigured to set + TasksMax= to a higher value. It is sufficient to set + TasksMax= in these specific unit files to a higher value, or + even "infinity". Similar, there's now a logind.conf setting + UserTasksMax= that defaults to 4096 and limits the total + number of processes or tasks each user may own + concurrently. nspawn containers also have the TasksMax= + value set by default now, to 8192. Note that all of this + only has an effect if the "pids" cgroup controller is + enabled in the kernel. The general benefit of these changes + should be a more robust and safer system, that provides a + certain amount of per-service fork() bomb protection. + * systemd-nspawn gained the new --network-veth-extra= switch to define additional and arbitrarily-named virtual Ethernet links between the host and the container. @@ -142,17 +175,18 @@ CHANGES WITH 228: Contributions from: Andrew Jones, Beniamino Galvani, Boyuan Yang, Daniel Machon, Daniel Mack, David Herrmann, David Reynolds, David Strauss, Dongsu Park, Evgeny Vereshchagin, - Filipe Brandenburger, Franck Bui, Hristo Venev, Iago López - Galeiras, Jan Engelhardt, Jan Janssen, Jan Synacek, Jesus - Ornelas Aguayo, Karel Zak, kayrus, Kay Sievers, Lennart - Poettering, Mantas Mikulėnas, Marcel Holtmann, Marcin Bachry, - Marcos Alano, Marcos Mello, Mark Theunissen, Martin Pitt, - Michael Marineau, Michael Olbrich, Michal Schmidt, Michal - Sekletar, Mirco Tischler, Nick Owens, Nicolas Cornu, Patrik - Flykt, Peter Hutterer, reverendhomer, Ronny Chevalier, - Sangjung Woo, Seong-ho Cho, Shawn Landden, Susant Sahani, - Thomas Haller, Thomas Hindoe Paaboel Andersen, Tom Gundersen, - Torstein Husebø, Vito Caputo, Zbigniew Jędrzejewski-Szmek + Felipe Sateler, Filipe Brandenburger, Franck Bui, Hristo + Venev, Iago López Galeiras, Jan Engelhardt, Jan Janssen, Jan + Synacek, Jesus Ornelas Aguayo, Karel Zak, kayrus, Kay Sievers, + Lennart Poettering, Liu Yuan Yuan, Mantas Mikulėnas, Marcel + Holtmann, Marcin Bachry, Marcos Alano, Marcos Mello, Mark + Theunissen, Martin Pitt, Michael Marineau, Michael Olbrich, + Michal Schmidt, Michal Sekletar, Mirco Tischler, Nick Owens, + Nicolas Cornu, Patrik Flykt, Peter Hutterer, reverendhomer, + Ronny Chevalier, Sangjung Woo, Seong-ho Cho, Shawn Landden, + Susant Sahani, Thomas Haller, Thomas Hindoe Paaboel Andersen, + Tom Gundersen, Torstein Husebø, Vito Caputo, Zbigniew + Jędrzejewski-Szmek -- Berlin, 2015-11-XX |
