CLONE_SIGHAND | CLONE_VM). But if sigaltstack is set by a\nparent thread, and then if multiple cloned child threads (+ parent threads)\ncall signal handler at the same time, some threads may be conflicted -\nbecause they share to use the same alternative signal stack region.\nFinally they get sigsegv.

Note that\nchild threads created from NPTL pthread_create() also hit this conflict\nwhen the parent thread uses sigaltstack, without my patch.\n\nTo fix this problem, this patch clears the child threads\u0027 sigaltstack\ninformation like exec(). This behavior follows the SUSv3 specification.\nIn SUSv3, pthread_create() says \"The alternate stack shall not be inherited\n(when new threads are initialized)\". It means that sigaltstack should be\ncleared when sigaltstack memory space is shared by cloned threads with\nCLONE_SIGHAND.\n\nNote that I chose \"if (clone_flags \u0026 CLONE_SIGHAND)\" line because:\n - If clone_flags line is not existed, fork() does not inherit sigaltstack.\n - CLONE_VM is another choice, but vfork() does not inherit sigaltstack.\n - CLONE_SIGHAND implies CLONE_VM, and it looks suitable.\n - CLONE_THREAD is another candidate, and includes CLONE_SIGHAND + CLONE_VM,\n but this flag has a bit different semantics.\nI decided to use CLONE_SIGHAND.\n\n[ Changed to test for CLONE_VM \u0026\u0026 !CLONE_VFORK after discussion --Linus ]\n\nSigned-off-by: GOTO Masanori \u003cgotom@sanori.org\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jakub Jelinek \u003cjakub@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7cd9013be6c22f3ff6f777354f766c8c0b955e17", "tree": "328e45aadb4c5bc9b6cd530be03572070201f5e5", "parents": [ "27d162e26a873883937b64526445877bd3341d23" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Sat Mar 11 03:27:18 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Mar 11 09:19:34 2006 -0800" }, "message": "[PATCH] remove __put_task_struct_cb export again\n\nThe patch \u0027[PATCH] RCU signal handling\u0027 [1] added an export for\n__put_task_struct_cb, a put_task_struct helper newly introduced in that\npatch.

The value returned is a fixed-point number in 52.12 format\nin nanoseconds. The reason for this format is that it gives the\nfull precision that the timekeeping code is using internally.\n\nThe motivation for this is to fix a problem that has arisen on 32-bit\npowerpc in that the value returned by do_gettimeofday drifts apart\nfrom xtime if NTP is being used. PowerPC is now using a lockless\ndo_gettimeofday based on reading the timebase register and performing\nsome simple arithmetic. (This method of getting the time is also\nexported to userspace via the VDSO.) However, the factor and offset\nit uses were calculated based on the nominal tick length and weren\u0027t\nbeing adjusted when NTP varied the tick length.\n\nNote that 64-bit powerpc has had the lockless do_gettimeofday for a\nlong time now. It also had an extremely hairy routine that got called\nfrom the 32-bit compat routine for adjtimex, which adjusted the\nfactor and offset according to what it thought the timekeeping code\nwas going to do. Not only was this only called if a 32-bit task did\nadjtimex (i.e. not if a 64-bit task did adjtimex), it was also\nduplicating computations from kernel/timer.c and it wasn\u0027t clear that\nit was (still) correct.\n\nThe simple solution is to ask the timekeeping code how long the\ncurrent jiffy will be on each timer interrupt, after calling\ndo_timer. If this jiffy will be a different length from the last one,\nwe then need to compute new values for the factor and offset used in\nthe lockless do_gettimeofday. In this way we can keep xtime and\ndo_gettimeofday in sync, even when NTP is varying the tick length.\n\nNote that when adjtimex varies the tick length, it almost always\nintroduces the variation from the next tick on. The only case I could\nsee where adjtimex would vary the length of the current tick is when\nan old-style adjtime adjustment is being cancelled. (It\u0027s not clear\nto me why the adjustment has to be cancelled immediately rather than\nfrom the next tick on.) Thus I don\u0027t see any real need for a hook in\nadjtimex; the rare case of an old-style adjustment being cancelled can\nbe fixed up at the next tick.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a62eaf151d9cb478d127cfbc2e93c498869785b0", "tree": "b13d62257ada7e0a9d37fdc9a69a7afa6f028b30", "parents": [ "99019e919969be88e7e4042f3afa296bd55ad9ec" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Thu Feb 16 23:41:58 2006 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Feb 17 08:00:40 2006 -0800" }, "message": "[PATCH] x86_64: Add boot option to disable randomized mappings and cleanup\n\nAMD SimNow!\u0027s JIT doesn\u0027t like them at all in the guest.

Each disk is 72Gb with a single ext3 filesystem (courtesy of HP, who\nsupplied benchmark results).\n\nThe problem is, for aim7, the wake-up pattern is random, but it still needs\nload balancing action in the wake-up path to achieve best performance. With\nthe above commit, lack of load balancing hurts that workload.\n\nHowever, for workloads like database transaction processing, the requirement\nis exactly opposite. In the wake up path, best performance is achieved with\nabsolutely zero load balancing. We simply wake up the process on the CPU that\nit was previously run. Worst performance is obtained when we do load\nbalancing at wake up.\n\nThere isn\u0027t an easy way to auto detect the workload characteristics. Ingo\u0027s\nearlier patch that detects idle CPU and decide whether to load balance or not\ndoesn\u0027t perform with aim7 either since all CPUs are busy (it causes even\nbigger perf. regression).\n\nRevert commit d7102e95b7b9c00277562c29aad421d2d521c5f6, which causes more\nthan 10% performance regression with aim7.\n\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "16bf134840da3920ded1290973c56ec214636f12", "tree": "1aacddb873bd383030a65e13e78c2ced38edfa23", "parents": [ "d98c7a09843621f1b145ca5ae8ed03ff04085edb" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Tue Feb 14 13:52:59 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Feb 14 16:09:33 2006 -0800" }, "message": "[PATCH] compound page: no access_process_vm check\n\nThe PageCompound check before access_process_vm\u0027s set_page_dirty_lock is no\nlonger necessary, so remove it.

while trying to remove temporary test\ndirectory. You can remove that temporary directory by doing rmdir, twice,\nfrom the command line. The first will fail with EBUSY, but the second will\nsucceed. I have reported the problem to Ram Pai and Al Viro with a small\nprogram which reproduces the problem. Al told us yesterday that he will be\nlooking at the problem soon. I have tried multiple rmdirs from the\nunshare_test program itself, but for some reason that is not working.

To solve this:\n\n- I\u0027ve added a \u0027domain distance\u0027 function, which is used to cache\n measurement results. Each distance is only measured once. This means\n that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT\n distances 0 and 1, and on SMP distance 0 is measured. The code walks\n the domain tree to determine the distance, so it automatically follows\n whatever hierarchy an architecture sets up. This cuts down on the boot\n time significantly and removes the O(N^2) limit. The only assumption\n is that migration costs can be expressed as a function of domain\n distance - this covers the overwhelming majority of existing systems,\n and is a good guess even for more assymetric systems.\n\n [ People hacking systems that have assymetries that break this\n assumption (e.g. different CPU speeds) should experiment a bit with\n the cpu_distance() function. Adding a -\u003emigration_distance factor to\n the domain structure would be one possible solution - but lets first\n see the problem systems, if they exist at all. Lets not overdesign. ]\n\nAnother problem was that only a single cache-size was used for measuring\nthe cost of migration, and most architectures didnt set that variable\nup. Furthermore, a single cache-size does not fit NUMA hierarchies with\nL3 caches and does not fit HT setups, where different CPUs will often\nhave different \u0027effective cache sizes\u0027. To solve this problem:\n\n- Instead of relying on a single cache-size provided by the platform and\n sticking to it, the code now auto-detects the \u0027effective migration\n cost\u0027 between two measured CPUs, via iterating through a wide range of\n cachesizes. The code searches for the maximum migration cost, which\n occurs when the working set of the test-workload falls just below the\n \u0027effective cache size\u0027. I.e. real-life optimized search is done for\n the maximum migration cost, between two real CPUs.\n\n This, amongst other things, has the positive effect hat if e.g. two\n CPUs share a L2/L3 cache, a different (and accurate) migration cost\n will be found than between two CPUs on the same system that dont share\n any caches.\n\n(The reliable measurement of migration costs is tricky - see the source\nfor details.)\n\nFurthermore i\u0027ve added various boot-time options to override/tune\nmigration behavior.\n\nFirstly, there\u0027s a blanket override for autodetection:\n\n\tmigration_cost\u003d1000,2000,3000\n\nwill override the depth 0/1/2 values with 1msec/2msec/3msec values.\n\nSecondly, there\u0027s a global factor that can be used to increase (or\ndecrease) the autodetected values:\n\n\tmigration_factor\u003d120\n\nwill increase the autodetected values by 20%. This option is useful to\ntune things in a workload-dependent way - e.g. if a workload is\ncache-insensitive then CPU utilization can be maximized by specifying\nmigration_factor\u003d0.\n\nI\u0027ve tested the autodetection code quite extensively on x86, on 3\nP3/Xeon/2MB, and the autodetected values look pretty good:\n\nDual Celeron (128K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 131072, cpu: 467 MHz):\n ---------------------\n [00] [01]\n [00]: - 1.7(1)\n [01]: 1.7(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 1.7 (1784008)\n ---------------------\n\nHere the slow memory subsystem dominates system performance, and even\nthough caches are small, the migration cost is 1.7 msecs.\n\nDual HT P4 (512K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 524288, cpu: 2379 MHz):\n ---------------------\n [00] [01] [02] [03]\n [00]: - 0.4(1) 0.0(0) 0.4(1)\n [01]: 0.4(1) - 0.4(1) 0.0(0)\n [02]: 0.0(0) 0.4(1) - 0.4(1)\n [03]: 0.4(1) 0.0(0) 0.4(1) -\n ---------------------\n cacheflush times [2]: 0.0 (33900) 0.4 (448514)\n ---------------------\n\nHere it can be seen that there is no migration cost between two HT\nsiblings (CPU#0/2 and CPU#1/3 are separate physical CPUs).
