These all need the basic abstraction of being\nable to group together multiple processes in an aggregate, in order to\ntrack/limit the resources permitted to those processes, or control\nother behaviour of the processes, and all implement this grouping in\ndifferent ways.\n\nThis patchset provides a framework for tracking and grouping processes\ninto arbitrary \"cgroups\" and assigning arbitrary state to those\ngroupings, in order to control the behaviour of the cgroup as an\naggregate.\n\nThe intention is that the various resource management and\nvirtualization/cgroup efforts can also become task cgroup\nclients, with the result that:\n\n- the userspace APIs are (somewhat) normalised\n\n- it\u0027s easier to test e.g. the ResGroups CPU controller in\n conjunction with the BeanCounters memory controller, or use either of\nthem as the resource-control portion of a virtual server system.\n\n- the additional kernel footprint of any of the competing resource\n management systems is substantially reduced, since it doesn\u0027t need\n to provide process grouping/containment, hence improving their\n chances of getting into the kernel\n\nThis patch:\n\nAdd the main task cgroups framework - the cgroup filesystem, and the\nbasic structures for tracking membership and associating subsystem state\nobjects to tasks.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Serge E.

This cpuset code would occassionally trigger that warning.\n\nThe fix is trivial -- check before storing into the array, not after, whether\nthe array is big enough to hold the store.\n\nCc: \"Eric W.

"message": "V3 file capabilities: alter behavior of cap_setpcap\n\nThe non-filesystem capability meaning of CAP_SETPCAP is that a process, p1,\ncan change the capabilities of another process, p2. This is not the\nmeaning that was intended for this capability at all, and this\nimplementation came about purely because, without filesystem capabilities,\nthere was no way to use capabilities without one process bestowing them on\nanother.\n\nSince we now have a filesystem support for capabilities we can fix the\nimplementation of CAP_SETPCAP.\n\nThe most significant thing about this change is that, with it in effect, no\nprocess can set the capabilities of another process.\n\nThe capabilities of a program are set via the capability convolution\nrules:\n\n pI(post-exec) \u003d pI(pre-exec)\n pP(post-exec) \u003d (X(aka cap_bset) \u0026 fP) | (pI(post-exec) \u0026 fI)\n pE(post-exec) \u003d fE ? pP(post-exec) : 0\n\nat exec() time. As such, the only influence the pre-exec() program can\nhave on the post-exec() program\u0027s capabilities are through the pI\ncapability set.\n\nThe correct implementation for CAP_SETPCAP (and that enabled by this patch)\nis that it can be used to add extra pI capabilities to the current process\n- to be picked up by subsequent exec()s when the above convolution rules\nare applied.\n\nHere is how it works:\n\nLet\u0027s say we have a process, p. It has capability sets, pE, pP and pI.\nGenerally, p, can change the value of its own pI to pI\u0027 where\n\n (pI\u0027 \u0026 ~pI) \u0026 ~pP \u003d 0.\n\nThat is, the only new things in pI\u0027 that were not present in pI need to\nbe present in pP.\n\nThe role of CAP_SETPCAP is basically to permit changes to pI beyond\nthe above:\n\n if (pE \u0026 CAP_SETPCAP) {\n pI\u0027 \u003d anything; /* ie., even (pI\u0027 \u0026 ~pI) \u0026 ~pP !\u003d 0 */\n }\n\nThis capability is useful for things like login, which (say, via\npam_cap) might want to raise certain inheritable capabilities for use\nby the children of the logged-in user\u0027s shell, but those capabilities\nare not useful to or needed by the login program itself.\n\nOne such use might be to limit who can run ping. You set the\ncapabilities of the \u0027ping\u0027 program to be \"\u003d cap_net_raw+i\", and then\nonly shells that have (pI \u0026 CAP_NET_RAW) will be able to run\nit. Without CAP_SETPCAP implemented as described above, login(pam_cap)\nwould have to also have (pP \u0026 CAP_NET_RAW) in order to raise this\ncapability and pass it on through the inheritable set.\n\nSigned-off-by: Andrew Morgan \u003cmorgan@kernel.org\u003e\nSigned-off-by: Serge E.

This is incredibly useful for debugging power management-related\nthings; however, having it as a compile-time option has proved to be\nincredibly inconvenient for us (OLPC). There are plenty of times that we\nwant serial console to not suspend, but for the most part we\u0027d like serial\nconsole to be suspended.\n\nThis drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel\nboot parameter (no_console_suspend). By default, the serial console will\nbe suspended along with the rest of the system; by passing\n\u0027no_console_suspend\u0027 to the kernel during boot, serial console will remain\nalive during suspend.\n\nFor now, this is pretty serial console specific; further fixes could be\napplied to make this work for things like netconsole.\n\nSigned-off-by: Andres Salomon \u003cdilinger@debian.org\u003e\nAcked-by: \"Rafael J.

However, the\ncost of turning it on in production system is quite high, largely due\nto number of events it collects and also due to its large memory\nfootprint.\n\nMost of the fields probably don\u0027t need to be full 64-bit on 64-bit\narch. Rolling over 4 billion events will most like take a long time\nand user space tool can be made to accommodate that. I\u0027m proposing\nkernel to cut back most of variable width on 64-bit system.
