Migrating the timer might delay it because\nwe can not reprogram the clock event device on the other CPU. But the\ncode implementing that check has two flaws:\n\n- for !HIGHRES the check compares the expiry value with the clock\n events device expiry value which is wrong for CLOCK_REALTIME based\n timers.\n\n- the check is racy. It holds the hrtimer base lock of the target CPU,\n but the clock event device expiry value can be modified\n nevertheless, e.g. by an timer interrupt firing.\n\nThe !HIGHRES case is easy to fix as we can enqueue the timer on the\ncpu which was selected by the load balancer. It runs the idle\nbalancing code once per jiffy anyway. So the maximum delay for the\ntimer is the same as when we keep the tick on the current cpu going.\n\nIn the HIGHRES case we can get the next expiry value from the hrtimer\ncpu_base of the target CPU and serialize the update with the cpu_base\nlock. This moves the lock section in hrtimer_interrupt() so we can set\nnext_event to KTIME_MAX while we are handling the expired timers and\nset it to the next expiry value after we handled the timers under the\nbase lock. While the expired timers are processed timer migration is\nblocked because the expiry time of the timer is always \u003c\u003d KTIME_MAX.\n\nAlso remove the now useless clockevents_get_next_event() function.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "7e0c5086c172ecf8b0c2ad860b02a586967d17d0", "tree": "207e1975ea970279e5ad912a094361e2fa169d93", "parents": [ "507e123151149e578c9aae33eb876c49824da5f8" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Jul 09 13:52:32 2009 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Jul 10 17:22:20 2009 +0200" }, "message": "hrtimer: migration: do not check expiry time on current CPU\n\nThe timer migration code needs to check whether the expiry time of the\ntimer is before the programmed clock event expiry time when the timer\nis enqueued on another CPU because we can not reprogram the timer\ndevice on the other CPU.

The read side still takes locks since\nwe still serialize readers. But the writers are the ones that\nmust be lockless (those can happen in NMIs).\n\nThe main change is to the \"head_page\" pointer. We write to the\ntail, and read from the head. The \"head_page\" pointer in the cpu\nbuffer is now just a reference to where to look. The real head\npage is now kept in the head_page-\u003elist-\u003eprev-\u003enext pointer.\nThat is, in the list head of the previous page we set flags.\n\nThe list pages are allocated to be aligned such that the lowest\nsignificant bits are always zero pointing to the list. This gives\nus play to put in flags to their pointers.\n\nbit 0: set when the page is a head page\nbit 1: set when the writer is moving the page (for overwrite mode)\n\ncmpxchg is used to update the pointer.\n\nWhen the writer wraps the buffer and the tail meets the head,\nin overwrite mode, the writer must move the head page forward.\nIt first uses cmpxchg to change the pointer flag from 1 to 2.\nOnce this is done, the reader on another CPU will not take the\npage from the buffer.\n\nThe writers need to protect against interrupts (we don\u0027t bother with\ndisabling interrupts because NMIs are allowed to write too).\n\nAfter the writer sets the pointer flag to 2, it takes care to\nmanage interrupts coming in. This is discribed in detail within the\ncomments of the code.\n\n Changes in version 2:\n - Let reader reset entries value of header page.\n - Fix tail page passing commit page on reader page test.\n - Always increment entries and write counter in rb_tail_page_update\n - Add safety check in rb_set_commit_to_write to break out of infinite loop\n - add mask in rb_is_reader_page\n\n[ Impact: lock free writing to the ring buffer ]\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "3adc54fa82a68be1cd1ac82ad786ee362796e50a", "tree": "0538fac360f776354ec6b171e6adb0049cfa9f3b", "parents": [ "ddc1637af217dbd8bc51f30e6d24e84476a869a6" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Mon Mar 30 15:32:01 2009 -0400" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Jul 07 18:36:10 2009 -0400" }, "message": "ring-buffer: make the buffer a true circular link list\n\nThis patch changes the ring buffer data pages from using a link list\nhead pointer, to making each buffer page point to another buffer page\nand never back to a \"head\".\n\nThis makes the handling of the ring buffer less complex, since the\ntraversing of the ring buffer pages no longer needs to account for the\nhead pointer.\n\nThis change also is needed to make the ring buffer lockless.\n\n[\n Changes in version 2:\n\n - Added change that Lai Jiangshan mentioned.\n\n From: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\n Date: Thu, 11 Jun 2009 11:25:48 +0800\n LKML-Reference: \u003c4A30793C.6090208@cn.fujitsu.com\u003e\n\n I\u0027m not sure whether these 4 lines:\n\tbpage \u003d list_entry(pages.next, struct buffer_page, list);\n\tlist_del_init(\u0026bpage-\u003elist);\n\tcpu_buffer-\u003epages \u003d \u0026bpage-\u003elist;\n\n\tlist_splice(\u0026pages, cpu_buffer-\u003epages);\n equal to these 2 lines:\n \tcpu_buffer-\u003epages \u003d pages.next;\n \tlist_del(\u0026pages);\n\n If there are equivalent, I think the second one\n are simpler.

write\naccess faults.\n\nThe patch was made on two wrong assumptions:\n\n1) access_ok(VERIFY_WRITE,...) would actually check write access.\n\n On x86 it does _NOT_. It\u0027s a pure address range check.\n\n2) a RW mapped region can not go away under us.\n\n That\u0027s wrong as well. Nobody can prevent another thread to call\n mprotect(PROT_READ) on that region where the futex resides. If that\n call hits between the get_user_pages_fast() verification and the\n actual write access in the atomic region we are toast again.\n\nThe solution is to not rely on access_ok and get_user() for any write\naccess related fault on private and shared futexes. Instead we need to\nfault it in with verification of write access.\n\nThere is no generic non destructive write mechanism which would fault\nthe user page in trough a #PF, but as we already know that we will\nfault we can as well call get_user_pages() directly and avoid the #PF\noverhead.\n\nIf get_user_pages() returns -EFAULT we know that we can not fix it\nanymore and need to bail out to user space.\n\nRemove a bunch of confusing comments on this issue as well.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: stable@kernel.org\n" }, { "commit": "f6faac71d502be1c29c81b2f45657662c3b84470", "tree": "b320a04b6f3955c60edaa30f47b889a0daf9f4b6", "parents": [ "4e8a2372f9255a1464ef488ed925455f53fbdaa1" ], "author": { "name": "Paul E.

Currently we hang suring\nboot in SLAB due to doing that too late.\n\nReported by James Bottomley and Sachin Sant (and possibly others).\nDebugged by Benjamin Herrenschmidt.\n\nThis just removes the dynamic initialization of the data structures, and\nreplaces it with a static one, avoiding this dependency entirely, and\nremoving one unnecessary special initcall.\n\nTested-by: Sachin Sant
