That is, with filesystem\nsupport for capabilities but without this present patch, it is (conceptually)\npossible to manage a system with capabilities alone and never need to obtain\nprivilege via (set)uid-0.\n\nOf course, conceptually isn\u0027t quite the same as currently possible since few\nuser applications, certainly not enough to run a viable system, are currently\nprepared to leverage capabilities to exercise privilege. Further, many\napplications exist that may never get upgraded in this way, and the kernel\nwill continue to want to support their setuid-0 base privilege needs.\n\nWhere pure-capability applications evolve and replace setuid-0 binaries, it is\ndesirable that there be a mechanisms by which they can contain their\nprivilege. In addition to leveraging the per-process bounding and inheritable\nsets, this should include suppressing the privilege of the uid-0 superuser\nfrom the process\u0027 tree of children.\n\nThe feature added by this patch can be leveraged to suppress the privilege\nassociated with (set)uid-0. This suppression requires CAP_SETPCAP to\ninitiate, and only immediately affects the \u0027current\u0027 process (it is inherited\nthrough fork()/exec()). This reimplementation differs significantly from the\nhistorical support for securebits which was system-wide, unwieldy and which\nhas ultimately withered to a dead relic in the source of the modern kernel.\n\nWith this patch applied a process, that is capable(CAP_SETPCAP), can now drop\nall legacy privilege (through uid\u003d0) for itself and all subsequently\nfork()\u0027d/exec()\u0027d children with:\n\n prctl(PR_SET_SECUREBITS, 0x2f);\n\nThis patch represents a no-op unless CONFIG_SECURITY_FILE_CAPABILITIES is\nenabled at configure time.\n\n[akpm@linux-foundation.org: fix uninitialised var warning]\n[serue@us.ibm.com: capabilities: use cap_task_prctl when !CONFIG_SECURITY]\nSigned-off-by: Andrew G.

The current code falls back to a global\ngroup rebalance in case the sched_domain\u0027s span it looks at has no shares, but\ndoes have tasks.\n\nThe reason it gets stuck here, is because its inherently racy - if someone\nsteals the last task after we compute the agg-\u003erq_weight, but before we\nrebalance, we\u0027ll never get out of the loop.\n\nWe could of course go fix that, but while looking at this issue I found that\nthis \u0027fallback\u0027 wasn\u0027t nearly as rare as I\u0027d hoped it to be. In fact its quite\ncommon - and given it walks the whole machine, thats very bad.\n\nThe new approach is simple (why didn\u0027t I think of it before?), we set the\naggregate shares to the full task group weight, and each larger sched domain\nthat encounters an aggregate shares larger than the weight, clips it (it\nalready re-distributes anyway).\n\nThis nicely converges to the desired global picture where the sum of all\nshares equals the task group weight.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "126e01bf92dfc5f0ba91e88be02c473e1506d7d9", "tree": "fe883f07319193bfbec244becc43e64a22e64f95", "parents": [ "88a411c07b6fedcfc97b8dc51ae18540bd2beda0" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 25 00:25:08 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 25 00:25:08 2008 +0200" }, "message": "softlockup: fix NOHZ wakeup\n\nDavid Miller reported:\n\n|---------------\u003e\nthe following commit:\n\n| commit 27ec4407790d075c325e1f4da0a19c56953cce23\n| Author: Ingo Molnar \u003cmingo@elte.hu\u003e\n| Date: Thu Feb 28 21:00:21 2008 +0100\n|\n| sched: make cpu_clock() globally synchronous\n|\n| Alexey Zaytsev reported (and bisected) that the introduction of\n| cpu_clock() in printk made the timestamps jump back and forth.\n|\n| Make cpu_clock() more reliable while still keeping it fast when it\u0027s\n| called frequently.\n|\n| Signed-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n\ncauses watchdog triggers when a cpu exits NOHZ state when it has been\nthere for \u003e\u003d the soft lockup threshold, for example here are some\nmessages from a 128 cpu Niagara2 box:\n\n[ 168.106406] BUG: soft lockup - CPU#11 stuck for 128s!

This can cause\ntime jumps in the range of hours.\n\nThis was reported in:\n http://lkml.org/lkml/2007/8/23/96\nand\n http://lkml.org/lkml/2008/3/31/23\n\nI was able to reproduce the problem with a gettimeofday loop test on a\ndual core and a quad core machine which both have sychronized\nTSCs. The TSCs seems not to be perfectly in sync though, but the\nkernel is not able to detect the slight delta in the sync check. Still\nthere exists an extremly small window where this delta can be observed\nwith a real big time jump. So far I was only able to reproduce this\nwith the vsyscall gettimeofday implementation, but in theory this\nmight be observable with the syscall based version as well.\n\nCPU 0 updates the clock source variables under xtime/vyscall lock and\nCPU1, where the TSC is slighty behind CPU0, is reading the time right\nafter the seqlock was unlocked.\n\nThe clocksource reference data was updated with the TSC from CPU0 and\nthe value which is read from TSC on CPU1 is less than the reference\ndata. This results in a huge delta value due to the unsigned\nsubtraction of the TSC value and the reference value. This algorithm\ncan not be changed due to the support of wrapping clock sources like\npm timer.\n\nThe huge delta is converted to nanoseconds and added to xtime, which\nis then observable by the caller. The next gettimeofday call on CPU1\nwill show the correct time again as now the TSC has advanced above the\nreference value.\n\nTo prevent this TSC specific wreckage we need to compare the TSC value\nagainst the reference value and return the latter when it is larger\nthan the actual TSC value.\n\nI pondered to mark the TSC unstable when the readout is smaller than\nthe reference value, but this would render an otherwise good and fast\nclocksource unusable without a real good reason.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "8fb402bccf203ecca8f9e0202b8fd3c937dece6f" }
