* [PATCH] Switch Kprobes inline functions to __kprobes for i386Prasanna S Panchamukhi2006-04-19
| | | | | | | | | | | | | | | Andrew Morton pointed out that compiler might not inline the functions marked for inline in kprobes. There-by allowing the insertion of probes on these kprobes routines, which might cause recursion. This patch removes all such inline and adds them to kprobes section there by disallowing probes on all such routines. Some of the routines can even still be inlined, since these routines gets executed after the kprobes had done necessay setup for reentrancy.

* [PATCH] apm: fix Armada laptops againSamuel Thibault2006-04-19
| | | | | | | | | | | | | | | | | | | Fix the "apm: set display: Interface not engaged" error on Armada laptops again. Jordan said: I think this is fine. It seems to me that this may be the fault of one or both of the APM solutions handling this situation in a non-standard way, but since APM is used very little on the Geode, and I have direct access to our BIOS folks, if this problem comes up with a customer again, we'll solve it from the firmware.

* [PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/Bjorn Helgaas2006-04-14
| | | | | | | | | | | | | | | | | | dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64. Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes. All three architectures already set CONFIG_DMI in their top-level Kconfig files.

* [PATCH] splice: add support for sys_tee()Jens Axboe2006-04-11
| | | | | | | | | | | | Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe. No data is copied, the output just grabs a reference to the input pipe data. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] No arch-specific strpbrk implementationsKyle McMartin2006-04-11
| | | | | | | | | | | | | | | While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

* [PATCH] swsusp: don't require bigsmpAshok Raj2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switching to automatic bigsmp causes a misleading error message, that more then 8 cpus are detected, and user needs to select either X86_GENERICARCH or X86_BIGSMP to handle. Reason is we switched to bigsmp to avoid IP race when new cpu is comming up. [bigsmp is nothing but using physical flat mode that can work for 1 .. 255 cpus] [default is X86_PC, that uses logical flat mode up to 8 CPUs max] Current x86_64 code uses bigsmp as default when hotplug is enabled. It would be preferable to make bigsmp as default, and work the dependencies of other related code like SMP_SUSPEND, and some related to memory hotplug code for i386. Current logical flat mode doesnt use shortcuts that cause the race by using the send_IPI_mask() instead of shortcuts when HOTPLUG_CPU is enabled. In the meantime this patch is the path of lease resistance. We will switch to bigsmp default sometime soon, when we get to work it again.

* Move request_standard_resources() back to before PCI probingLinus Torvalds2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively undoes the PCI resource allocation changes done in commit b408cbc704352eccee301e1103b23203ba1c3a0e, but leaves the cleanups of that commit in place. We're going back to marking the resources reported by e820 busy _before_ doing PCI probing, so that any PCI resource that clashes with the BIOS- reported memory map will be reloacted to a non-clashing area. The reason? Larry Finger reports that his laptop has the cardbus controller set up by the BIOS so that it conflicts with the e820 memory map, and needs to be relocated. See http://bugzilla.kernel.org/show_bug.cgi?id=6337 for more details. We'll have to work out how to handle the fbcon problem that caused that commit in the first place in some other way.

* [PATCH] i386: Consolidate modern APIC handlingAndi Kleen2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | AMD systems have a modern APIC that supports 8 bit IDs, but don't have a XAPIC version number. Add a new "modern_apic" subfunction that handles this correctly and use it (nearly) everywhere where XAPIC is tested for. I removed one wart: the code specified that external APICs would use an 8bit APIC ID. But I checked a real 82093 data sheet and it says clearly that they only use 4bit. So I removed this special case since it would a bit awkward to implement now. I removed the valid APIC tests in mptable parsing completely. On any modern system they only check against the full field width (8bit) anyways and are no-ops. This also fixes them doing the wrong thing on >8 core Opterons. This makes i386 boot again on 16 core Opterons. Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Reasons: - It's more flexible. Things which would require two or three syscalls with fadvise() can be done in a single syscall. - Using fadvise() in this manner is something not covered by POSIX. The patch wires up the syscall for x86. The sycall is implemented in the new fs/sync.c. The intention is that we can move sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later. Documentation for the syscall is in fs/sync.c. A test app (sync_file_range.c) is in http://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz. The available-to-GPL-modules do_sync_file_range() is for knfsd: "A COMMIT can say NFS_DATA_SYNC or NFS_FILE_SYNC. I can skip the ->fsync call for NFS_DATA_SYNC which is hopefully the more common." Note: the `async' writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if the queue is congested. This is trivial to fix: add a new flag bit, set wbc->nonblocking. But I'm not sure that we want to expose implementation details down to that level. Note: it's notable that we can sync an fd which wasn't opened for writing. Same with fsync() and fdatasync()). Note: the code takes some care to handle attempts to sync file contents outside the 16TB offset on 32-bit machines. It makes such attempts appear to succeed, for best 32-bit/64-bit compatibility. Perhaps it should make such requests fail...

If ->setup_func() returns 0, obsolete_checksetup() tries other ->setup_func(). If all ->setup_func() that matched a parameter returns 0, a parameter is seted to argv_init[]. Then, when runing /sbin/init or init=app, argv_init[] is passed to the app. If the app doesn't ignore those arguments, it will warning and exit.

Currently it does not lead to boot failure in second kernel as timer interrupts continues to come as ExtInt through LAPIC directly, but fixing it is good in case some boards do not support the other mode. o After a system crash, it is not safe to service interrupts any more, hence interrupts are disabled. This leads to pending interrupts at LAPIC. LAPIC sends these interrupts to the CPU during early boot of second kernel. Other pending interrupts are discarded saying unexpected trap but timer interrupt is serviced and CPU does not issue an LAPIC EOI because it think this interrupt came from i8259 and sends ack to 8259. This leads to vector 0x31 locking as LAPIC does not clear respective ISR and keeps on waiting for EOI. o This patch issues extra EOI for the pending interrupts who have ISR set. o Though today only timer seems to be the special case because in early boot it thinks interrupts are coming from i8259 and uses mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI. But probably doing it in generic manner for all vectors makes sense. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: "Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the sys_splice system call. Using a pipe as a transport, it can connect to files or sockets (latter as output only). From the splice.c comments: "splice": joining two ropes together by interweaving their strands. This is the "extended pipe" functionality, where a pipe is used as an arbitrary in-memory buffer. Think of a pipe as a small kernel buffer that you can use to transfer data from one end to the other. The traditional unix read/write is extended with a "splice()" operation that transfers data buffers to or from a pipe buffer. Named by Larry McVoy, original implementation from Linus, extended by Jens to support splicing to files and fixing the initial implementation bugs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel's implementation of notifier chains is unsafe. There is no protection against entries being added to or removed from a chain while the chain is in use. The issues were discussed in this thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 We noticed that notifier chains in the kernel fall into two basic usage classes: "Blocking" chains are always called from a process context and the callout routines are allowed to sleep; "Atomic" chains can be called from an atomic context and the callout routines are not allowed to sleep. We decided to codify this distinction and make it part of the API. Therefore this set of patches introduces three new, parallel APIs: one for blocking notifiers, one for atomic notifiers, and one for "raw" notifiers (which is really just the old API under a new name). New kinds of data structures are used for the heads of the chains, and new routines are defined for registration, unregistration, and calling a chain. The three APIs are explained in include/linux/notifier.h and their implementation is in kernel/sys.c. With atomic and blocking chains, the implementation guarantees that the chain links will not be corrupted and that chain callers will not get messed up by entries being added or removed. For raw chains the implementation provides no guarantees at all; users of this API must provide their own protections. (The idea was that situations may come up where the assumptions of the atomic and blocking APIs are not appropriate, so it should be possible for users to handle these things in their own way.) There are some limitations, which should not be too hard to live with. For atomic/blocking chains, registration and unregistration must always be done in a process context since the chain is protected by a mutex/rwsem. Also, a callout routine for a non-raw chain must not try to register or unregister entries on its own chain. (This did happen in a couple of places and the code had to be changed to avoid it.) Since atomic chains may be called from within an NMI handler, they cannot use spinlocks for synchronization. Instead we use RCU. The overhead falls almost entirely in the unregister routine, which is okay since unregistration is much less frequent that calling a chain. Here is the list of chains that we adjusted and their classifications. None of them use the raw API, so for the moment it is only a placeholder. ATOMIC CHAINS ------------- arch/i386/kernel/traps.c: i386die_chain arch/ia64/kernel/traps.c: ia64die_chain arch/powerpc/kernel/traps.c: powerpc_die_chain arch/sparc64/kernel/traps.c: sparc64die_chain arch/x86_64/kernel/traps.c: die_chain drivers/char/ipmi/ipmi_si_intf.c: xaction_notifier_list kernel/panic.c: panic_notifier_list kernel/profile.c: task_free_notifier net/bluetooth/hci_core.c: hci_notifier net/ipv4/netfilter/ip_conntrack_core.c: ip_conntrack_chain net/ipv4/netfilter/ip_conntrack_core.c: ip_conntrack_expect_chain net/ipv6/addrconf.c: inet6addr_chain net/netfilter/nf_conntrack_core.c: nf_conntrack_chain net/netfilter/nf_conntrack_core.c: nf_conntrack_expect_chain net/netlink/af_netlink.c: netlink_chain BLOCKING CHAINS --------------- arch/powerpc/platforms/pseries/reconfig.c: pSeries_reconfig_chain arch/s390/kernel/process.c: idle_chain arch/x86_64/kernel/process.c idle_notifier drivers/base/memory.c: memory_chain drivers/cpufreq/cpufreq.c cpufreq_policy_notifier_list drivers/cpufreq/cpufreq.c cpufreq_transition_notifier_list drivers/macintosh/adb.c: adb_client_list drivers/macintosh/via-pmu.c sleep_notifier_list drivers/macintosh/via-pmu68k.c sleep_notifier_list drivers/macintosh/windfarm_core.c wf_client_list drivers/usb/core/notify.c usb_notifier_list drivers/video/fbmem.c fb_notifier_list kernel/cpu.c cpu_chain kernel/module.c module_notify_list kernel/profile.c munmap_notifier kernel/profile.c task_exit_notifier kernel/sys.c reboot_notifier_list net/core/dev.c netdev_chain net/decnet/dn_dev.c: dnaddr_chain net/ipv4/devinet.c: inetaddr_chain It's possible that some of these classifications are wrong. If they are, please let us know or submit a patch to fix them. Note that any chain that gets called very frequently should be atomic, because the rwsem read-locking used for blocking chains is very likely to incur cache misses on SMP systems. (However, if the chain's callout routines may sleep then the chain cannot be atomic.)

This patch consolidates all of them. One minor glitch is that at least i386 uses them in a very skeletal header file. To keep away from #include dependency hell, I stuck the new definitions in a new, isolated header. Of all of the implementations, sh64 is the only one that varied by a bit. It used some masks to ensure that any sign-extension got ripped away before the arithmetic is done. This has been posted to that sh64 maintainers and the development list.

| * [PATCH] sched: new sched domain for representing multi-coreSiddha, Suresh B2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new sched domain for representing multi-core with shared caches between cores. Consider a dual package system, each package containing two cores and with last level cache shared between cores with in a package. If there are two runnable processes, with this appended patch those two processes will be scheduled on different packages. On such systems, with this patch we have observed 8% perf improvement with specJBB(2 warehouse) benchmark and 35% improvement with CFP2000 rate(with 2 users). This new domain will come into play only on multi-core systems with shared caches. On other systems, this sched domain will be removed by domain degeneration code. This new domain can be also used for implementing power savings policy (see OLS 2005 CMP kernel scheduler paper for more details.. I will post another patch for power savings policy soon) Most of the arch/* file changes are for cpu_coregroup_map() implementation.

If chip is buggy, warnings "pmtmr is slow". But sounds like there is gray zone. I found the PIIX4 errata, but I couldn't find the ICH4 errata. But some motherboard seems to have problem. So, if we found a ICH4, generate warnings, and use a workaround version. If user's ICH4 is good, the user can specify the "pmtmr_good" boot parameter to use fast version.

| * [PATCH] x86: kprobes-boosterMasami Hiramatsu2006-03-26

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