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.

So define as macros that return appropriately instead (int\n\u00270\u0027 for the register_hotcpu_notifier case and void for\nunregister_hotcpu_notifier).\n\nSigned-off-by: Satyam Sharma \u003csatyam@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f494f8fcb18e962839a82d542fbe6bed9cf5be07", "tree": "bf5b0ce1119df05607a8111bed5047fffb305709", "parents": [ "c66f08be7e3ad0a28bcd9a0aef766fdf08ea0ec6" ], "author": { "name": "Michael Neuling", "email": "mneuling@au1.ibm.com", "time": "Thu Oct 18 03:06:35 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:28 2007 -0700" }, "message": "add-scaled-time-to-taskstats-based-process-accounting fix\n\nThis moves the new items to the end of the taskstats struct as\nrequested by Balbir and yourself.\n\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c66f08be7e3ad0a28bcd9a0aef766fdf08ea0ec6", "tree": "d147c0a43a66973014d924a6020388a249c509a7", "parents": [ "898eb71cb17644964c5895fb190e79e3d0c49679" ], "author": { "name": "Michael Neuling", "email": "mikey@neuling.org", "time": "Thu Oct 18 03:06:34 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:28 2007 -0700" }, "message": "Add scaled time to taskstats based process accounting\n\nThis adds items to the taststats struct to account for user and system\ntime based on scaling the CPU frequency and instruction issue rates.\n\nAdds account_(user|system)_time_scaled callbacks which architectures\ncan use to account for time using this mechanism.\n\nSigned-off-by: Michael Neuling \u003cmikey@neuling.org\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "65f76a82ec7a0374fad85211535330e203740475", "tree": "351838854d96086ee86e4daaaf64dbd9c0264b30", "parents": [ "1c0a387c1f9e48e480579d3b4e0f9c1a36c77751" ], "author": { "name": "Jiri Slaby", "email": "jirislaby@gmail.com", "time": "Thu Oct 18 03:06:22 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:26 2007 -0700" }, "message": "Char: cyclades, fix some -W warnings\n\nMost of them are signedness, the rest unused function parameters.\n\nSigned-off-by: Jiri Slaby \u003cjirislaby@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ebafeeff0fea029099e9952f233e0794106897a6", "tree": "50bc3ca7f9d4c7153c3e98bda28199dcc6eff948", "parents": [ "c43422053bea7a5ce09f18d0c50a606fe1a549f4" ], "author": { "name": "Jiri Slaby", "email": "jirislaby@gmail.com", "time": "Thu Oct 18 03:06:20 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:26 2007 -0700" }, "message": "Char: cyclades, remove bottom half processing\n\nThe work done in bottom half doesn\u0027t cost much cpu time (e.g. tty_hangup\nitself schedules its own bottom half), it\u0027s possible to do the work in isr\ndirectly and save hence some .text.\n\nSigned-off-by: Jiri Slaby \u003cjirislaby@gmail.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "72c2d5823fc7be799a12184974c3bdc57acea3c4", "tree": "5c17418efb57cd5b2cdc0d751f577b2c64012423", "parents": [ "7058cb02ddab4bce70a46e519804fccb7ac0a060" ], "author": { "name": "Andrew Morgan", "email": "morgan@kernel.org", "time": "Thu Oct 18 03:05:59 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:24 2007 -0700" }, "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.
