This\nwill cause erroneous imbalance calculation.\n\nThe reason is that calculate_imbalance() sees sds-\u003eavg_load \u003d 0 and it\nwill dump entire sds-\u003emax_load into imbalance variable, which is used\nlater on to migrate entire load from busiest CPU to the puller CPU.\n\nThis has two really bad effect:\n\n1. stampede of task migration, and they won\u0027t be able to break out\n of the bad state because of positive feedback loop: large load\n delta -\u003e heavier load migration -\u003e larger imbalance and the cycle\n goes on.\n\n2. severe imbalance in CPU queue depth. This causes really long\n scheduling latency blip which affects badly on application that\n has tight latency requirement.\n\nThe fix is to have kernel calculate domain avg_load in both cases. This\nwill ensure that imbalance calculation is always sensible and the target\nis usually half way between busiest and puller CPU.\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: \u003cstable@kernel.org\u003e\nLink: http://lkml.kernel.org/r/20110408002322.3A0D812217F@elm.corp.google.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e566b76ed30768140df8f0023904aed5a41244f7", "tree": "5d8fa756453cb6f60554c6c253a3cf2a01945628", "parents": [ "621d26567fd0c222f419e3b5ddf39e529e0fdcb3" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Wed Apr 06 02:54:54 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Apr 11 11:07:55 2011 +0200" }, "message": "perf_event: Fix cgrp event scheduling bug in perf_enable_on_exec()\n\nThere is a bug in perf_event_enable_on_exec() when cgroup events are\nactive on a CPU: the cgroup events may be scheduled twice causing event\nstate corruptions which eventually may lead to kernel panics.\n\nThe reason is that the function needs to first schedule out the cgroup\nevents, just like for the per-thread events.

They\n will be privileged with respect to the new namespace, but this should\n only include resources which the unprivileged user already owns.\n\n- Provide separate limits and accounting for userids in different\n namespaces.\n\nStatus:\n\n Currently (as of 2.6.38) you can clone with the CLONE_NEWUSER flag to\n get a new user namespace if you have the CAP_SYS_ADMIN, CAP_SETUID, and\n CAP_SETGID capabilities. What this gets you is a whole new set of\n userids, meaning that user 500 will have a different \u0027struct user\u0027 in\n your namespace than in other namespaces. So any accounting information\n stored in struct user will be unique to your namespace.\n\n However, throughout the kernel there are checks which\n\n - simply check for a capability. Since root in a child namespace\n has all capabilities, this means that a child namespace is not\n constrained.\n\n - simply compare uid1 \u003d\u003d uid2. Since these are the integer uids,\n uid 500 in namespace 1 will be said to be equal to uid 500 in\n namespace 2.\n\n As a result, the lxc implementation at lxc.sf.net does not use user\n namespaces. This is actually helpful because it leaves us free to\n develop user namespaces in such a way that, for some time, user\n namespaces may be unuseful.\n\nBugs aside, this patchset is supposed to not at all affect systems which\nare not actively using user namespaces, and only restrict what tasks in\nchild user namespace can do. They begin to limit privilege to a user\nnamespace, so that root in a container cannot kill or ptrace tasks in the\nparent user namespace, and can only get world access rights to files.\nSince all files currently belong to the initila user namespace, that means\nthat child user namespaces can only get world access rights to *all*\nfiles. While this temporarily makes user namespaces bad for system\ncontainers, it starts to get useful for some sandboxing.\n\nI\u0027ve run the \u0027runltplite.sh\u0027 with and without this patchset and found no\ndifference.\n\nThis patch:\n\ncopy_process() handles CLONE_NEWUSER before the rest of the namespaces.\nSo in the case of clone(CLONE_NEWUSER|CLONE_NEWUTS) the new uts namespace\nwill have the new user namespace as its owner. That is what we want,\nsince we want root in that new userns to be able to have privilege over\nit.\n\nChangelog:\n\tFeb 15: don\u0027t set uts_ns-\u003euser_ns if we didn\u0027t create\n\t\ta new uts_ns.\n\tFeb 23: Move extern init_user_ns declaration from\n\t\tinit/version.c to utsname.h.\n\nSigned-off-by: Serge E.
