This can happen in combination with the conntrack event cache, which holds a reference to the conntrack entry, which is only released when the packet makes it all the way through the stack or a different packet is handled. - taking references to an unconfirmed entry and using it outside the locked section doesn't work, the list entries are not refcounted and another CPU might already be waiting to destroy the entry What the code really wants to do is make sure the references of the hash table to the selected conntrack entries are released, so they will be destroyed once all references from skbs and the event cache are dropped. Since unconfirmed entries haven't even entered the hash yet, simply mark them as dying and skip confirmation based on that.

And with this my laptop (Lenovo T60) also stopped its sporadic hard hanging (sometimes in acpi_init(), sometimes later during bootup, sometimes much later during actual use) as well. It hung with both nmi_watchdog=1 and nmi_watchdog=2, so it's generally the fact of NMI injection that is causing problems, not the NMI watchdog variant, nor any particular bootup code.

This happens because we have the following code in kernel/hrtimer.c: migrate_hrtimers(int cpu) [...] old_base = &per_cpu(hrtimer_bases, cpu); new_base = &get_cpu_var(hrtimer_bases); [...] spin_lock(&new_base->lock); spin_lock(&old_base->lock); Which means the spinlocks are taken in an order which depends on which cpu gets shut down from which other cpu. Therefore lockdep complains that there might be an ABBA deadlock. Since migrate_hrtimers() gets only called on cpu hotplug it's safe to assume that it isn't executed concurrently on a The same problem exists in kernel/timer.c: migrate_timers(). As pointed out by Christian Borntraeger one possible solution to avoid the locking order complaints would be to make sure that the locks are always taken in the same order. E.g. by taking the lock of the cpu with the lower number first. To achieve this we introduce two new spinlock functions double_spin_lock and double_spin_unlock which lock or unlock two locks in a given order.

| 6bb74df | john stultz | 05 March 2007, 08:30:50 UTC | [PATCH] clocksource init adjustments (fix bug #7426) This patch resolves the issue found here: http://bugme.osdl.org/show_bug.cgi?id=7426 The basic summary is: Currently we register most of i386/x86_64 clocksources at module_init time. Then we enable clocksource selection at late_initcall time. This causes some problems for drivers that use gettimeofday for init calibration routines (specifically the es1968 driver in this case), where durring module_init, the only clocksource available is the low-res jiffies clocksource. This may cause slight calibration errors, due to the small sampling time used. It should be noted that drivers that require fine grained time may not function on architectures that do not have better then jiffies resolution timekeeping (there are a few). However, this does not discount the reasonable need for such fine-grained timekeeping at init time. Thus the solution here is to register clocksources earlier (ideally when the hardware is being initialized), and then we enable clocksource selection at fs_initcall (before device_initcall). This patch should probably get some testing time in -mm, since clocksource selection is one of the most important issues for correct timekeeping, and I've only been able to test this on a few of my own boxes.

Many places in the raid5 code used "conf->raid_disks-1" to mean "number of data disks". With raid6 that had to be changed to "conf->raid_disk - conf->max_degraded" or similar. One place was missed. This bug means that if a raid6 reshape were aborted in the middle the recorded position would be wrong.

| e30fab3 | Zachary Amsden | 05 March 2007, 08:30:39 UTC | [PATCH] vmi: pit override The time_init_hook in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through an indirect function pointer in the paravirt-ops table. The problem is, by the time the paravirt hook is called, the pit timer is already enabled. But paravirt guests have their own timer, and don't want to use the PIT. Rather than intensify the struggle for power going on here, just make it all nice and simple and just unconditionally do all timer setup in the late_time_init hook. This also has the advantage of enabling timers in the same place in all code paths, so everyone has the same bugs and we don't have outliers who break other code because they turn on timer too early or too late. So the paravirt-ops time init function is now by default hpet_time_init, which is the time init function used for native hardware. Paravirt guests have the chance to override this when they setup the paravirt-ops table, and should need no change.

This can be noticed by any device that interacts with the real world in real time - like AP startup, which takes real time. Or keyboard LEDs, which should blink in real-time. Or floppy drives, but only when passed through to a real floppy controller on OSes which can't sufficiently buffer the floppy commands to emulate a zero latency floppy. Or IDE drives, when connecting to a physical CDROM.

The result from sched_clock needs to be in nanoseconds, not in CPU cycles. The TSC is insufficient for this purpose, because TSC is poorly defined in a virtual environment, and mostly represents real world time instead of scheduled process time (which can be interrupted without notice when a virtual machine is descheduled). To make the scheduler consistent, we must expose a different nature of time, that is scheduled time. So deprecate this custom_sched_clock hack and turn it into a paravirt-op, as it should have been all along. This allows the tsc.c code which converts cycles to nanoseconds to be shared by all paravirt-ops backends. It is unfortunate to add a new paravirt-op, but this is a very distinct abstraction which is clearly different for all virtual machine implementations, and it gets rid of an ugly indirect function which I ashamedly admit I hacked in to try to get this to work earlier, and then even got in the wrong units.

Additionally, since the periodic alarm can be run at a lower rate than HZ, let's fixup the guard to the no-idle-hz mode appropriately. This fixes the bug where the no-idle-hz mode might have a higher interrupt rate than the non-idle case. 2) The interrupt handler can no longer adjust xtime due to nested lock acquisition. Drop this. We don't need to check for wallclock time at every tick, it can be done in userspace instead. 3) Add a bypass to disable noidle operation. This is useful as a last minute workaround, or testing measure. 4) The code to skip the IO_APIC timer testing (no_timer_check) should be conditional on IO_APIC, not SMP, since UP kernels can have this configured in as well.

The reason for this is that the strnicmp() for both heads uses a sizeof() for the string length, which ends up being strlen() + 1 (\0 in the normal case, but the echo gives a newline, which is where the issue occurs), this then causes a mismatch and subsequently bails with the -EINVAL. In addition to this, the hardcoded lengths were then used for the store length that was returned, which ended up being erroneous and resulting in a write error. There's also no point in returning anything but the full length since it will -EINVAL out on a mismatch well before then anyways. sizeof("string") is great for making sure you have space in your buffer, but rather less so for string comparisons :-) Signed-off-by: Paul Mundt <lethal@linux-sh.org> Acked-by: Ben Dooks <ben-linux@fluff.org> Cc: "Antonino A.

So this patch replaces them with with two much more targeted functions: msi_set_enable and msix_set_enable. This patch makes pci_dev->msi_enabled and pci_dev->msix_enabled the definitive way to test if linux has enabled the msi capability, and has the appropriate msi data structures set up. This patch ensures that while writing the msi messages in save/restore and during device initialization we have the msi capability disabled so we don't get into races. The pci spec requires that we do not have the msi capability enabled and the msi messages unmasked while we write the messages. Completely disabling the capability is overkill but it is easy :) Care has been taken so we never have both a msi capability and intx enabled simultaneously.

Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

| bccf215 | Avi Kivity | 21 February 2007, 16:04:26 UTC | KVM: Per-vcpu inodes Allocate a distinct inode for every vcpu in a VM. This has the following benefits: - the filp cachelines are no longer bounced when f_count is incremented on every ioctl() - the API and internal code are distinctly clearer; for example, on the KVM_GET_REGS ioctl, there is no need to copy the vcpu number from userspace and then copy the registers back; the vcpu identity is derived from the fd used to make the call Right now the performance benefits are completely theoretical since (a) we don't support more than one vcpu per VM and (b) virtualization hardware inefficiencies completely everwhelm any cacheline bouncing effects. But both of these will change, and we need to prepare the API today. Signed-off-by: Avi Kivity <avi@qumranet.com> | 04 March 2007, 09:12:42 UTC |
