For this race to trigger the process that proc_pid_readdir stops at\nmust exit before readdir is called again.\n\nThis can cause ps to fail to report processes, and it is in violation of\nposix guarantees and normal application expectations with respect to\nreaddir.\n\nCurrently there is no way to work around this problem in user space short\nof providing a gargantuan buffer to user space so the directory read all\nhappens in on system call.\n\nThis patch implements the normal directory semantics for proc, that\nguarantee that a directory entry that is neither created nor destroyed\nwhile reading the directory entry will be returned. For directory that are\neither created or destroyed during the readdir you may or may not see them.\n Furthermore you may seek to a directory offset you have previously seen.\n\nThese are the guarantee that ext[23] provides and that posix requires, and\nmore importantly that user space expects. Plus it is a simple semantic to\nimplement reliable service. It is just a matter of calling readdir a\nsecond time if you are wondering if something new has show up.\n\nThese better semantics are implemented by scanning through the pids in\nnumerical order and by making the file offset a pid plus a fixed offset.\n\nThe pid scan happens on the pid bitmap, which when you look at it is\nremarkably efficient for a brute force algorithm. Given that a typical\ncache line is 64 bytes and thus covers space for 64*8 \u003d\u003d 200 pids. There\nare only 40 cache lines for the entire 32K pid space. A typical system\nwill have 100 pids or more so this is actually fewer cache lines we have to\nlook at to scan a linked list, and the worst case of having to scan the\nentire pid bitmap is pretty reasonable.\n\nIf we need something more efficient we can go to a more efficient data\nstructure for indexing the pids, but for now what we have should be\nsufficient.\n\nIn addition this takes no additional locks and is actually less code than\nwhat we are doing now.\n\nAlso another very subtle bug in this area has been fixed. It is possible\nto catch a task in the middle of de_thread where a thread is assuming the\nthread of it\u0027s thread group leader. This patch carefully handles that case\nso if we hit it we don\u0027t fail to return the pid, that is undergoing the\nde_thread dance.\n\nThanks to KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e for\nproviding the first fix, pointing this out and working on it.\n\n[oleg@tv-sign.ru: fix it]\nSigned-off-by: Eric W.

I ran out of time before doing that though.\n\nThe demo prototype scripts weren\u0027t very good. If there is really interest I\ncan dig them out (they are currently on a laptop disk on the desk with the\nlaptop itself being in service), but I would recommend to rewrite them for any\nserious application of this and fix the disk space problem.\n\nAlso to be really useful it should probably find a way to automatically fetch\nthe debuginfos (I cheated and just installed them in advance). If nobody else\ndoes it I can probably do the rewrite myself again at some point.\n\nMy hope at some point was that desktops would support it in their builtin\ncrash reporters, but at least the KDE people I talked too seemed to be happy\nwith their user space only solution.\n\nAlan sayeth:\n\n I don\u0027t believe that piping as such as neccessarily the right model, but\n the ability to intercept and processes core dumps from user space is asked\n for by many enterprise users as well. They want to know about, capture,\n analyse and process core dumps, often centrally and in automated form.\n\n[akpm@osdl.org: loff_t !\u003d unsigned long]\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e239ca540594cff00adcce163dc332b27015d8e5", "tree": "8dfb5c0be4864d738df5a5282e56d9e57ce8261f", "parents": [ "d6cbd281d189977b38eac7eb2a4678de19b6b483" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Sat Sep 30 23:29:27 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:33 2006 -0700" }, "message": "[PATCH] Create call_usermodehelper_pipe()\n\nA new member in the ever growing family of call_usermode* functions is\nborn.

The\ncode that today makes this tradeoff just does a rather simple algorithm;\nhowever this is not good enough: There are devices and use cases where a\nlower latency is required than that the higher power saving states provide.\n An example would be audio playback, but another example is the ipw2100\nwireless driver that right now has a very direct and ugly acpi hook to\ndisable some higher power states randomly when it gets certain types of\nerror.\n\nThe proposed solution is to have an interface where drivers can\n\n* announce the maximum latency (in microseconds) that they can deal with\n* modify this latency\n* give up their constraint\n\nand a function where the code that decides on power saving strategy can\nquery the current global desired maximum.\n\nThis patch has a user of each side: on the consumer side, ACPI is patched\nto use this, on the producer side the ipw2100 driver is patched.\n\nA generic maximum latency is also registered of 2 timer ticks (more and you\nlose accurate time tracking after all).\n\nWhile the existing users of the patch are x86 specific, the infrastructure\nis not. I\u0027d like to ask the arch maintainers of other architectures if the\ninfrastructure is generic enough for their use (assuming the architecture\nhas such a tradeoff as concept at all), and the sound/multimedia driver\nowners to look at the driver facing API to see if this is something they\ncan use.\n\n[akpm@osdl.org: cleanups]\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Jesse Barnes \u003cjesse.barnes@intel.com\u003e\nCc: \"Brown, Len\" \u003clen.brown@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9361401eb7619c033e2394e4f9f6d410d6719ac7", "tree": "04b94a71f2366988c17740d1c16cfbdec41d5d2e", "parents": [ "d366e40a1cabd453be6e2609caa7e12f9ca17b1f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Sat Sep 30 20:45:40 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:52:31 2006 +0200" }, "message": "[PATCH] BLOCK: Make it possible to disable the block layer [try #6]\n\nMake it possible to disable the block layer.

An old check for a possibly null task\ncpuset pointer needed to be changed to a check for a task marked\nPF_EXITING.

In that\ncase, the wrong cpuset reference counter would be decremented.\n\nThe fix is trivial. Instead of failing the system call if the tasks cpuset\npointer is null here, fail it if the task is in PF_EXITING state.\n\nThe code for \u0027the_top_cpuset_hack\u0027 that changes an exiting tasks cpuset to\nthe top_cpuset is done without locking, so could happen at anytime.

Make this top cpus file read-only.\n\nOn systems that have cpusets configured in their kernel, but that aren\u0027t\nactively using cpusets (for some distros, this covers the majority of\nsystems) all tasks end up in the top cpuset.\n\nIf that system does support memory hotplug, then these tasks cannot make\nuse of memory nodes that are added after system boot, because the memory\nnodes are not allowed in the top cpuset. This is a surprising regression\nover earlier kernels that didn\u0027t have cpusets enabled.\n\nOne key motivation for this change is to remain consistent with the\nbehaviour for the top_cpuset\u0027s \u0027cpus\u0027, which is also read-only, and which\nautomatically tracks the cpu_online_map.\n\nThis change also has the minor benefit that it fixes a long standing,\nlittle noticed, minor bug in cpusets. The cpuset performance tweak to\nshort circuit the cpuset_zone_allowed() check on systems with just a single\ncpuset (see \u0027number_of_cpusets\u0027, in linux/cpuset.h) meant that simply\nchanging the \u0027mems\u0027 of the top_cpuset had no affect, even though the change\n(the write system call) appeared to succeed. With the following change,\nthat write to the \u0027mems\u0027 file fails -EACCES, and the \u0027mems\u0027 file stubbornly\nrefuses to be changed via user space writes. Thus no one should be mislead\ninto thinking they\u0027ve changed the top_cpusets\u0027s \u0027mems\u0027 when in affect they\nhaven\u0027t.\n\nIn order to keep the behaviour of cpusets consistent between systems\nactively making use of them and systems not using them, this patch changes\nthe behaviour of the \u0027mems\u0027 file in the top (root) cpuset, making it read\nonly, and making it automatically track the value of node_online_map. Thus\ntasks in the top cpuset will have automatic use of hot plugged memory nodes\nallowed by their cpuset.\n\n[akpm@osdl.org: build fix]\n[bunk@stusta.de: build fix]\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c394cc9fbb367f87faa2228ec2eabacd2d4701c6", "tree": "2177214ac92b3a7ac21cb2632786c9de728c3868", "parents": [ "55a101f8f71a3d3dbda7b5c77083ffe47552f831" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Fri Sep 29 02:01:11 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:21 2006 -0700" }, "message": "[PATCH] introduce TASK_DEAD state\n\nI am not sure about this patch, I am asking Ingo to take a decision.\n\ntask_struct-\u003estate \u003d\u003d EXIT_DEAD is a very special case, to avoid a confusion\nit makes sense to introduce a new state, TASK_DEAD, while EXIT_DEAD should\nlive only in -\u003eexit_state as documented in sched.h.\n\nNote that this state is not visible to user-space, get_task_state() masks off\nunsuitable states.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "55a101f8f71a3d3dbda7b5c77083ffe47552f831", "tree": "52706df201efd82d09bed39562502b4caa357af4", "parents": [ "29b884921634e1e01cbd276e1c9b8fc07a7e4a90" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Fri Sep 29 02:01:10 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:20 2006 -0700" }, "message": "[PATCH] kill PF_DEAD flag\n\nAfter the previous change (-\u003eflags \u0026 PF_DEAD) \u003c\u003d\u003e (-\u003estate \u003d\u003d EXIT_DEAD), we\ndon\u0027t need PF_DEAD any longer.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "29b884921634e1e01cbd276e1c9b8fc07a7e4a90", "tree": "951fce8626715b1ad26ca81bec9002cfcb8242af", "parents": [ "e8106b941ceab68cc5ff713df7b1276484554584" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Fri Sep 29 02:01:09 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:20 2006 -0700" }, "message": "[PATCH] set EXIT_DEAD state in do_exit(), not in schedule()\n\nschedule() checks PF_DEAD on every context switch and sets -\u003estate \u003d EXIT_DEAD\nto ensure that the exiting task will be deactivated.
