This approach provides\nsimilar properties to specifying a device and partition number, but using\nthe UUID as the unique path prior to evaluating the offset.\n\nFor example,\n root\u003dPARTUUID\u003d99DE9194-FC15-4223-9192-FC243948F88B/PARTNROFF\u003d1\nselects the partition with UUID 99DE.. then select the next\npartition.\n\nThis change is motivated by a particular

provides a direct mechanism for the user\nto modify the root partition to boot without specifically needing to\nextract each UUID or update the bootloader explicitly when the root\npartition UUID is changed (if it is recreated to be larger, for instance).\n Pinning to a /boot-style partition UUID allows the arbitrary root\npartition reconfiguration/modifications with slightly less ambiguity

Case 2 is less\ndramatic since the earlier fix in this area and also intermittent.\n\n Re: bogomips discrepancy on Intel Core2 Quad CPU -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d118929277524298\u0026w\u003d4\n slow system and bogus bogomips -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d116791286716107\u0026w\u003d4\n Re: Re: [RFC-PATCH] clocksource: update lpj if clocksource has -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d128952775819467\u0026w\u003d4\n\nThis issue is masked a little by commit feae3203d711db0a (\"timers, init:\nLimit the number of per cpu calibration bootup messages\") which only\nprints out the first bogoMIPS value making it much harder to notice other\nvalues differing.

This\noption is then used by \u0027make\u0027 to determine whether an extra kallsyms\npass is needed or not.\n\nHowever, this approach is not nice and confusing, and this patch moves\nCONFIG_KALLSYMS_EXTRA_PASS from Kconfig to Makefile instead. The\nrationale is below.\n\n1. CONFIG_KALLSYMS_EXTRA_PASS is really about the build time, not\n run-time. There is no real need for it to be in Kconfig. It is\n just an additional work-around which should be used only in rare\n cases, when someone breaks kallsyms, so Kbuild/Makefile is much\n better place for this option.\n2. Grepping CONFIG_KALLSYMS_EXTRA_PASS shows that many defconfigs have\n it enabled, probably not because they try to work-around a kallsyms\n bug, but just because the Kconfig help text is confusing and does\n not really make it clear that this option should not be used unless\n except when kallsyms is broken.\n3. And since many people have CONFIG_KALLSYMS_EXTRA_PASS enabled in\n their Kconfig, we do might fail to notice kallsyms bugs in time. E.g.,\n many testers use \"make allyesconfig\" to test builds, which will enable\n CONFIG_KALLSYMS_EXTRA_PASS and kallsyms breakage will not be noticed.\n\nTo address that, this patch:\n\n1. Kills CONFIG_KALLSYMS_EXTRA_PASS\n2. Changes Makefile so that people can use \"make KALLSYMS_EXTRA_PASS\u003d1\"\n to enable the extra pass if needed. Additionally, they may define\n KALLSYMS_EXTRA_PASS as an environment variable.\n3. By default KALLSYMS_EXTRA_PASS is disabled and if kallsyms has issues,\n \"make\" should print a warning and suggest using KALLSYMS_EXTRA_PASS\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n[mmarek: Removed make help text, is not necessary]\nSigned-off-by: Michal Marek \u003cmmarek@suse.cz\u003e\n" }, { "commit": "71a83ec7da8910f374a1c82e96d2704aa45d9238", "tree": "29d76d098aad49f92e3a745fb87c17d90511f524", "parents": [ "0ce790e7d736cedc563e1fb4e998babf5a4dbc3d" ], "author": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Tue Apr 05 13:24:57 2011 +0300" }, "committer": { "name": "Michal Marek", "email": "mmarek@suse.cz", "time": "Fri Apr 15 15:48:01 2011 +0200" }, "message": "Kconfig: improve KALLSYMS_ALL documentation\n\nDumb users like myself are not able to grasp from the existing KALLSYMS_ALL\ndocumentation that this option is not what they need.

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.

This is a lengthy process,\ntaking 0.2s in an environment where boot time is of great interest.\n\nPatch 2/4 has two optimisations. Firstly, it replaces the initial\nrepeated- doubling to find the relevant power of 2 with a tight loop that\njust does as much as it can in a jiffy. Secondly, it doesn\u0027t binary chop\nover an entire power of 2 range, it choses a much smaller range based on\nhow much it squeezed in, and failed to squeeze in, during the first stage.\n Both are significant optimisations, and bring our calibration down from\n23 jiffies to 5, and, in the process, often arrive at a more accurate lpj\nvalue.\n\nThe \u0027bands\u0027 and \u0027sub-logarithmic\u0027 growth may look over-engineered, but\nthey only cost a small level of inaccuracy in the initial guess (for all\narchitectures) in order to avoid the very large inaccuracies that appeared\nduring testing (on x86_64 architectures, and presumably others with less\nmetronomic operation). Note that due to the existence of the TSC and\nother timers, the x86_64 will not typically use this fallback routine, but\nI wanted to code defensively, able to cope with all kinds of processor\nbehaviours and kernel command line options.\n\nPatch 3/4 is an additional trap for the nightmare scenario where the\ninitial estimate is very inaccurate, possibly due to things like SMIs.\nIt simply retries with a larger bound.\n\nStephen said:\n\nI tried this patch set out on an MSM7630.\n:\n: Before:\n:\n: Calibrating delay loop... 681.57 BogoMIPS (lpj\u003d3407872)\n:\n: After:\n:\n: Calibrating delay loop... 680.75 BogoMIPS (lpj\u003d3403776)\n:\n: But the really good news is calibration time dropped from ~247ms to ~56ms.\n: Sadly we won\u0027t be able to benefit from this should my udelay patches make\n: it into ARM because we would be using calibrate_delay_direct() instead (at\n: least on machines who choose to). Can we somehow reapply the logic behind\n: this to calibrate_delay_direct()? That would be even better, but this is\n: definitely a boot time improvement.\n:\n: Or maybe we could just replace calibrate_delay_direct() with this fallback\n: calculation? If __delay() is a thin wrapper around read_current_timer()\n: it should work just as well (plus patch 3 makes it handle SMIs). I\u0027ll try\n: that out.\n\nThis patch:\n\n... so that it can be modified more clinically.\n\nThis is almost entirely cosmetic. The only change to the operation\nis that the global variable is only set once after the estimation is\ncompleted, rather than taking on all the intermediate values. However,\nthere are no readers of that variable, so this change is unimportant.\n\nSigned-off-by: Phil Carmody \u003cext-phil.2.carmody@nokia.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: \"H.

This patch\nimplements an idea from Linus, to automatically create task\ngroups. Currently, only per session autogroups are implemented,\nbut the patch leaves the way open for enhancement.\n\nImplementation: each task\u0027s signal struct contains an inherited\npointer to a refcounted autogroup struct containing a task group\npointer, the default for all tasks pointing to the\ninit_task_group. When a task calls setsid(), a new task group\nis created, the process is moved into the new task group, and a\nreference to the preveious task group is dropped. Child\nprocesses inherit this task group thereafter, and increase it\u0027s\nrefcount. When the last thread of a process exits, the\nprocess\u0027s reference is dropped, such that when the last process\nreferencing an autogroup exits, the autogroup is destroyed.\n\nAt runqueue selection time, IFF a task has no cgroup assignment,\nits current autogroup is used.\n\nAutogroup bandwidth is controllable via setting it\u0027s nice level\nthrough the proc filesystem:\n\n cat /proc/\u003cpid\u003e/autogroup\n\nDisplays the task\u0027s group and the group\u0027s nice level.\n\n echo \u003cnice level\u003e \u003e /proc/\u003cpid\u003e/autogroup\n\nSets the task group\u0027s shares to the weight of nice \u003clevel\u003e task.\nSetting nice level is rate limited for !admin users due to the\nabuse risk of task group locking.\n\nThe feature is enabled from boot by default if\nCONFIG_SCHED_AUTOGROUP\u003dy is selected, but can be disabled via\nthe boot option noautogroup, and can also be turned on/off on\nthe fly via:\n\n echo [01] \u003e /proc/sys/kernel/sched_autogroup_enabled\n\n... which will automatically move tasks to/from the root task group.\n\nSigned-off-by: Mike Galbraith \u003cefault@gmx.de\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Markus Trippelsdorf \u003cmarkus@trippelsdorf.de\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Paul Turner \u003cpjt@google.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\n[ Removed the task_group_path() debug code, and fixed !EVENTFD build failure. ]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nLKML-Reference: \u003c1290281700.28711.9.camel@maggy.simson.net\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "46fdb0937f26124700fc9fc80da4776330cc00d3" }
