Things which would require two or three syscalls with\n fadvise() can be done in a single syscall.\n\n- Using fadvise() in this manner is something not covered by POSIX.\n\nThe patch wires up the syscall for x86.\n\nThe sycall is implemented in the new fs/sync.c. The intention is that we can\nmove sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.\n\nDocumentation for the syscall is in fs/sync.c.\n\nA test app (sync_file_range.c) is in\nhttp://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.\n\nThe available-to-GPL-modules do_sync_file_range() is for knfsd: \"A COMMIT can\nsay NFS_DATA_SYNC or NFS_FILE_SYNC. I can skip the -\u003efsync call for\nNFS_DATA_SYNC which is hopefully the more common.\"\n\nNote: the `async\u0027 writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if\nthe queue is congested. This is trivial to fix: add a new flag bit, set\nwbc-\u003enonblocking. But I\u0027m not sure that we want to expose implementation\ndetails down to that level.\n\nNote: it\u0027s notable that we can sync an fd which wasn\u0027t opened for writing.\nSame with fsync() and fdatasync()).\n\nNote: the code takes some care to handle attempts to sync file contents\noutside the 16TB offset on 32-bit machines. It makes such attempts appear to\nsucceed, for best 32-bit/64-bit compatibility. Perhaps it should make such\nrequests fail...\n\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Neil Brown \u003cneilb@cse.unsw.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9b41046cd0ee0a57f849d6e1363f7933e363cca9", "tree": "246820e9493770e071cb92a48e7f72d8b9c90a98", "parents": [ "68eef3b4791572ecb70249c7fb145bb3742dd899" ], "author": { "name": "OGAWA Hirofumi", "email": "hirofumi@mail.parknet.co.jp", "time": "Fri Mar 31 02:30:33 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 31 12:18:53 2006 -0800" }, "message": "[PATCH] Don\u0027t pass boot parameters to argv_init[]\n\nThe boot cmdline is parsed in parse_early_param() and\nparse_args(,unknown_bootoption).\n\nAnd __setup() is used in obsolete_checksetup().\n\n\tstart_kernel()\n\t\t-\u003e parse_args()\n\t\t\t-\u003e unknown_bootoption()\n\t\t\t\t-\u003e obsolete_checksetup()\n\nIf __setup()\u0027s callback (-\u003esetup_func()) returns 1 in\nobsolete_checksetup(), obsolete_checksetup() thinks a parameter was\nhandled.\n\nIf -\u003esetup_func() returns 0, obsolete_checksetup() tries other\n-\u003esetup_func().

Currently it does not lead to boot\n failure in second kernel as timer interrupts continues to come as ExtInt\n through LAPIC directly, but fixing it is good in case some boards do not\n support the other mode.\n\no After a system crash, it is not safe to service interrupts any more,\n hence interrupts are disabled. This leads to pending interrupts at\n LAPIC. LAPIC sends these interrupts to the CPU during early boot of\n second kernel. Other pending interrupts are discarded saying unexpected\n trap but timer interrupt is serviced and CPU does not issue an LAPIC EOI\n because it think this interrupt came from i8259 and sends ack to 8259.\n This leads to vector 0x31 locking as LAPIC does not clear respective ISR\n and keeps on waiting for EOI.\n\no This patch issues extra EOI for the pending interrupts who have ISR set.\n\no Though today only timer seems to be the special case because in early\n boot it thinks interrupts are coming from i8259 and uses\n mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI.

There is no\nprotection against entries being added to or removed from a chain while the\nchain is in use. The issues were discussed in this thread:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113018709002036\u0026w\u003d2\n\nWe noticed that notifier chains in the kernel fall into two basic usage\nclasses:\n\n\t\"Blocking\" chains are always called from a process context\n\tand the callout routines are allowed to sleep;\n\n\t\"Atomic\" chains can be called from an atomic context and\n\tthe callout routines are not allowed to sleep.\n\nWe decided to codify this distinction and make it part of the API. Therefore\nthis set of patches introduces three new, parallel APIs: one for blocking\nnotifiers, one for atomic notifiers, and one for \"raw\" notifiers (which is\nreally just the old API under a new name). New kinds of data structures are\nused for the heads of the chains, and new routines are defined for\nregistration, unregistration, and calling a chain. The three APIs are\nexplained in include/linux/notifier.h and their implementation is in\nkernel/sys.c.\n\nWith atomic and blocking chains, the implementation guarantees that the chain\nlinks will not be corrupted and that chain callers will not get messed up by\nentries being added or removed. For raw chains the implementation provides no\nguarantees at all; users of this API must provide their own protections. (The\nidea was that situations may come up where the assumptions of the atomic and\nblocking APIs are not appropriate, so it should be possible for users to\nhandle these things in their own way.)\n\nThere are some limitations, which should not be too hard to live with. For\natomic/blocking chains, registration and unregistration must always be done in\na process context since the chain is protected by a mutex/rwsem. Also, a\ncallout routine for a non-raw chain must not try to register or unregister\nentries on its own chain. (This did happen in a couple of places and the code\nhad to be changed to avoid it.)\n\nSince atomic chains may be called from within an NMI handler, they cannot use\nspinlocks for synchronization. Instead we use RCU. The overhead falls almost\nentirely in the unregister routine, which is okay since unregistration is much\nless frequent that calling a chain.\n\nHere is the list of chains that we adjusted and their classifications. None\nof them use the raw API, so for the moment it is only a placeholder.\n\n ATOMIC CHAINS\n -------------\narch/i386/kernel/traps.c:\t\ti386die_chain\narch/ia64/kernel/traps.c:\t\tia64die_chain\narch/powerpc/kernel/traps.c:\t\tpowerpc_die_chain\narch/sparc64/kernel/traps.c:\t\tsparc64die_chain\narch/x86_64/kernel/traps.c:\t\tdie_chain\ndrivers/char/ipmi/ipmi_si_intf.c:\txaction_notifier_list\nkernel/panic.c:\t\t\t\tpanic_notifier_list\nkernel/profile.c:\t\t\ttask_free_notifier\nnet/bluetooth/hci_core.c:\t\thci_notifier\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_chain\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_expect_chain\nnet/ipv6/addrconf.c:\t\t\tinet6addr_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_expect_chain\nnet/netlink/af_netlink.c:\t\tnetlink_chain\n\n BLOCKING CHAINS\n ---------------\narch/powerpc/platforms/pseries/reconfig.c:\tpSeries_reconfig_chain\narch/s390/kernel/process.c:\t\tidle_chain\narch/x86_64/kernel/process.c\t\tidle_notifier\ndrivers/base/memory.c:\t\t\tmemory_chain\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_policy_notifier_list\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_transition_notifier_list\ndrivers/macintosh/adb.c:\t\tadb_client_list\ndrivers/macintosh/via-pmu.c\t\tsleep_notifier_list\ndrivers/macintosh/via-pmu68k.c\t\tsleep_notifier_list\ndrivers/macintosh/windfarm_core.c\twf_client_list\ndrivers/usb/core/notify.c\t\tusb_notifier_list\ndrivers/video/fbmem.c\t\t\tfb_notifier_list\nkernel/cpu.c\t\t\t\tcpu_chain\nkernel/module.c\t\t\t\tmodule_notify_list\nkernel/profile.c\t\t\tmunmap_notifier\nkernel/profile.c\t\t\ttask_exit_notifier\nkernel/sys.c\t\t\t\treboot_notifier_list\nnet/core/dev.c\t\t\t\tnetdev_chain\nnet/decnet/dn_dev.c:\t\t\tdnaddr_chain\nnet/ipv4/devinet.c:\t\t\tinetaddr_chain\n\nIt\u0027s possible that some of these classifications are wrong.

When the kernel hits the probe\npoint, kprobe handler is invoked. And the copied instruction is single-step\nexecuted on the copied buffer (not on the original address) by kprobe. After\nthat, the kprobe checks registers and modify it (if need) as if the\ninstructions was executed on the original address.\n\nMy proposal is based on the fact there are many instructions which do NOT\nrequire the register modification after the single-step execution. When the\ncopied instruction is a kind of them, kprobe just jumps back to the next\ninstruction after single-step execution. If so, why don\u0027t we execute those\ninstructions directly?\n\nWith kprobe-booster patch, kprobes will execute a copied instruction directly\nand (if need) jump back to original code. This direct execution is executed\nwhen the kprobe don\u0027t have both post_handler and break_handler, and the copied\ninstruction can be executed directly.\n\nI sorted instructions which can be executed directly or not;\n\n- Call instructions are NG(can not be executed directly).\n We should correct the return address pushed into top of stack.\n- Indirect instructions except for absolute indirect-jumps\n are NG. Those instructions changes EIP randomly. We should\n check EIP and correct it.\n- Instructions that change EIP beyond the range of the\n instruction buffer are NG.\n- Instructions that change EIP to tail 5 bytes of the\n instruction buffer (it is the size of a jump instruction).\n We must write a jump instruction which backs to original\n kernel code in the instruction buffer.\n- Break point instruction is NG. We should not touch EIP and\n pass to other handlers.\n- Absolute direct/indirect jumps are OK.- Conditional Jumps are NG.\n- Halt and software-interruptions are NG. Because it will stay on\n the instruction buffer of kprobes.\n- Prefixes are NG.\n- Unknown/reserved opcode is NG.\n- Other 1 byte instructions are OK. But those instructions need a\n jump back code.\n- 2 bytes instructions are mapped sparsely. So, in this release,\n this patch don\u0027t boost those instructions.\n\n\u003eFrom Intel\u0027s IA-32 opcode map described in IA-32 Intel Architecture Software\nDeveloper\u0027s Manual Vol.2 B, I determined that following opcodes are not\nboostable.\n\n- 0FH (2byte escape)\n- 70H - 7FH (Jump on condition)\n- 9AH (Call) and 9CH (Pushf)\n- C0H-C1H (Grp 2: includes reserved opcode)\n- C6H-C7H (Grp11: includes reserved opcode)\n- CCH-CEH (Software-interrupt)\n- D0H-D3H (Grp2: includes reserved opcode)\n- D6H (Reserved)\n- D8H-DFH (Coprocessor)\n- E0H-E3H (loop/conditional jump)\n- E8H (Call)\n- F0H-F3H (Prefixes and reserved)\n- F4H (Halt)\n- F6H-F7H (Grp3: includes reserved opcode)\n- FEH-FFH(Grp4,5: includes reserved opcode)\n\nKprobe-booster checks whether target instruction can be boosted (can be\nexecuted directly) at arch_copy_kprobe() function. If the target instruction\ncan be boosted, it clears \"boostable\" flag. If not, it sets \"boostable\" flag\n-1. This is disabled status. In resume_execution() function, If \"boostable\"\nflag is cleared, kprobe-booster measures the size of the target instruction\nand sets \"boostable\" flag 1.\n\nIn kprobe_handler(), kprobe checks the \"boostable\" flag. If the flag is 1, it\nresets current kprobe and executes instruction buffer directly instead of\nsingle stepping.\n\nWhen unregistering a boosted kprobe, it calls synchronize_sched()\nafter \"int3\" is removed. So we can ensure followings after\nthe synchronize_sched() called.\n- interrupt handlers are finished on all CPUs.\n- instruction buffer is not executed on all CPUs.\nAnd we can release the boosted kprobe safely.\n\nAnd also, on preemptible kernel, the booster is not enabled where the kernel\npreemption is enabled. So, there are no preempted threads on the instruction\nbuffer.\n\nThe description of kretprobe-booster:\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nIn the normal operation, kretprobe make a target function return to trampoline\ncode. And a kprobe (called trampoline_probe) have been inserted at the\ntrampoline code. When the kernel hits this kprobe, it calls kretprobe\u0027s\nhandler and it returns to original return address.\n\nKretprobe-booster patch removes the trampoline_probe. It allows the\ntram\u0018poline code to call kretprobe\u0027s handler directly instead of invoking\nkprobe. And tranpoline code returns to original return address.\n\nThis new trampoline code stores and restores registers, so the kretprobe\nhandler is still able to access those registers.\n\nCurrent kprobe has about 1.3 usec/probe(*) overhead, and kprobe-booster patch\nreduces it to 0.6 usec/probe(*). Also current kretprobe has about 2.0\nusec/probe(*) overhead. Kprobe-booster patch reduces it to 1.3 usec/probe(*),\nand the combination of both kprobe-booster patch and kretprobe-booster patch\nreduces it to 0.9 usec/probe(*).\n\nI expect the combination of both patches can reduce half of a probing\noverhead.\n\nPerformance numbers strongly depend on the processor model.\n\nAndrew Morton wrote:\n\u003e These preempt tricks look rather nasty. Can you please describe what the\n\u003e problem is, precisely? And how this code avoids it? Perhaps we can find\n\u003e something cleaner.\n\nThe problem is how to remove the copied instructions of the\nkprobe *safely* on the preemptable kernel (CONFIG_PREEMPT\u003dy).\n\nKprobes basically executes the following actions;\n\n(1)int3\n(2)preempt_disable()\n(3)kprobe_prehandler()\n(4)copied instructioin(single step)\n(5)kprobe_posthandler()\n(6)preempt_enable()\n(7)return to the original code\n\nDuring the execution of copied instruction, preemption is\ndisabled (from step (2) to (6)).\nWhen unregistering the probes, Kprobe waits for RCU\nquiescent state by using synchronize_sched() after removing\nint3 instruction.\nThus we can ensure the copied instruction is not executed.\n\nOn the other hand, kprobe-booster executes the following actions;\n\n(1)int3\n(2)preempt_disable()\n(3)kprobe_prehandler()\n(4)preempt_enable() \u003c-- this one is added by my patch\n(5)copied instruction(direct execution)\n(6)jmp back to the original code\n\nThe problem is that we have no way to prevent preemption on\nstep (5) or (6). We cannot call preempt_disable() after step (6),\nbecause there are no rooms to do that. Thus, some other\nprocesses may be preempted at step(5) or (6) on preemptable kernel.\nAnd I couldn\u0027t find the easy way to ensure that other processes\u0027\nstack do *not* have the address of them. (I thought some way\nto do that, but those are very costly.)\n\nSo currently, I simply boost the kprobe only when the probe\npoint is already preemption disabled.\n\n\u003e Also, the patch adds a preempt_enable() but I don\u0027t see a corresponding\n\u003e preempt_disable(). Am I missing something?\n\nIt is corresponding to the preempt_disable() in the top of\nkprobe_handler().\nI copied the code of kprobe_handler() here:\n\nstatic int __kprobes kprobe_handler(struct pt_regs *regs)\n{\n struct kprobe *p;\n int ret \u003d 0;\n kprobe_opcode_t *addr \u003d NULL;\n unsigned long *lp;\n struct kprobe_ctlblk *kcb;\n\n /*\n * We don\u0027t want to be preempted for the entire\n * duration of kprobe processing\n */\n preempt_disable(); \u003c-- HERE\n kcb \u003d get_kprobe_ctlblk();\n\nSigned-off-by: Masami Hiramatsu \u003chiramatu@sdl.hitachi.co.jp\u003e\nCc: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: David S.

However, it\u0027s pretty clear that the e820 entries are there for a\nreason. Probably they are a hack by the BIOS maintainers to keep Windows\nfrom stomping/moving that region, exactly because they want to keep the\nbridge where it is (or, it\u0027s actually for the BIOS itself - the BIOS\ntables are a horrid mess, and BIOS engineers are pretty hacky people:\nthey\u0027ll add random entries to make their own broken algorithms do the\n\"right thing\").\n\n\u003e Starting from 2.6.13, kernel tries to resolve that sort of conflicts,\n\u003e so that prefetch window of the bridge and the framebuffer memory behind\n\u003e it get moved to 0x10000000.\n\nI think we could (and probably should) solve this another way: consider\nthe ACPI \"reserved regions\" from the e820 map exactly the same way that we\ndo other ACPI hints - they should restrict _new_ allocations, but not\nimpact stuff we figure out on our own.\n\nBasically, right now we assign _unassigned_ resources at \"fs_initcall\"\ntime. If we were to add in the e820 \"reserved region\" stuff before that\n(but after we\u0027ve done PCI discovery), we\u0027d probably do the right thing.\n\nRight now we do the e820 reserved regions very early indeed: we call\n\"register_memory()\" from setup_arch(). We could move at least part of it\n(the part that registers the resources) down a bit.\n\nHere\u0027s a test-patch. I\u0027m not saying we should absolutely do this, but it\nmight be interesting to try...\n\nCc: \"Antonino A.

The next system call will then free the context for\nitself and for the vm86 context, thus generating the above messages. This\npatch addresses the issue by simply adding a call to \u0027audit_syscall_exit\u0027\nfrom the vm86 code.\n\nBesides fixing the above error messages the patch also now allows vm86\nsystem calls to become auditable. This is useful since strace does not\nappear to properly record the return values from sys_vm86.\n\nI think this patch is also a step in the right direction in terms of\ncleaning up some core auditing code. If we can correct any other paths\nthat do not properly call the audit exit and entries points, then we can\nalso eliminate the notion of context chaining.\n\nI\u0027ve tested this patch by verifying that the log messages no longer\nappear, and that the audit records for sys_vm86 appear to be correct.\nAlso, \u0027read_edid\u0027 produces itentical output.\n\nthanks,\n\n-Jason\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" } ], "next": "82c3c03a4096badd026c6e337f3c5dde020e9ec6" }
