block: use nanosecond resolution for iostat
|
|
Klaus Kusche reported that the I/O busy time in /proc/diskstats was not
updating properly on 4.18. This is because we started using ktime to
track elapsed time, and we convert nanoseconds to jiffies when we update
the partition counter. However, this gets rounded down, so any I/Os that
take less than a jiffy are not accounted for. Previously in this case,
the value of jiffies would sometimes increment while we were doing I/O,
so at least some I/Os were accounted for.
Let's convert the stats to use nanoseconds internally. We still report
milliseconds as before, now more accurately than ever. The value is
still truncated to 32 bits for backwards compatibility.

"It's mostly small bugfixes and cleanups, mostly around x86 nested
virtualization. One important change, not related to nested
virtualization, is that the ability for the guest kernel to trap
CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
now masked by default. This is because the feature is detected
through an MSR; a very bad idea that Intel seems to like more and
more. Some applications choke if the other fields of that MSR are
not initialized as on real hardware, hence we have to disable the
whole MSR by default, as was the case before Linux 4.12."

The naked attribute is supported by at least gcc >= 4.6 (for ARM,
which is the only current user), gcc >= 8 (for x86), clang >= 3.1
and icc >= 13. See https://godbolt.org/z/350Dyc
Therefore, move it out of compiler-gcc.h so that the definition

Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access
to reads of MSR_PLATFORM_INFO.
Disabling access to reads of this MSR gives userspace the control to "expose"
this platform-dependent information to guests in a clear way. As it exists
today, guests that read this MSR would get unpopulated information if userspace
hadn't already set it (and prior to this patch series, only the CPUID faulting
information could have been populated). This existing interface could be
confusing if guests don't handle the potential for incorrect/incomplete
information gracefully (e.g. zero reported for base frequency).

Scrubbing pages on initial balloon down can take some time, especially
in nested virtualization case (nested EPT is slow). When HVM/PVH guest is
started with memory= significantly lower than maxmem=, all the extra
pages will be scrubbed before returning to Xen. But since most of them
weren't used at all at that point, Xen needs to populate them first
(from populate-on-demand pool). In nested virt case (Xen inside KVM)
this slows down the guest boot by 15-30s with just 1.5GB needed to be
returned to Xen.
Add runtime parameter to enable/disable it, to allow initially disabling
scrubbing, then enable it back during boot (for example in initramfs).
Such usage relies on assumption that a) most pages ballooned out during
initial boot weren't used at all, and b) even if they were, very few
secrets are in the guest at that time (before any serious userspace
kicks in).
Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also
enabled by default), controlling default value for the new runtime
switch.

CONFIG_INDIRECT_PIO
The !CONFIG_GENERIC_IOMAP version of ioport_map uses MMIO_UPPER_LIMIT to
prevent users from making I/O accesses outside the expected I/O range -
however it erroneously treats MMIO_UPPER_LIMIT as a mask which is
contradictory to its other users.
The introduction of CONFIG_INDIRECT_PIO, which subtracts an arbitrary
amount from IO_SPACE_LIMIT to form MMIO_UPPER_LIMIT, results in ioport_map
mangling the given port rather than capping it.
We address this by aligning more closely with the CONFIG_GENERIC_IOMAP
implementation of ioport_map by using the comparison operator and
returning NULL where the port exceeds MMIO_UPPER_LIMIT. Though note that
we preserve the existing behavior of masking with IO_SPACE_LIMIT such that
we don't break existing buggy drivers that somehow rely on this masking.

Jann Horn points out that the vmacache_flush_all() function is not only
potentially expensive, it's buggy too. It also happens to be entirely
unnecessary, because the sequence number overflow case can be avoided by
simply making the sequence number be 64-bit. That doesn't even grow the
data structures in question, because the other adjacent fields are
already 64-bit.
So simplify the whole thing by just making the sequence number overflow
case go away entirely, which gets rid of all the complications and makes
the code faster too. Win-win.
[ Oleg Nesterov points out that the VMACACHE_FULL_FLUSHES statistics
also just goes away entirely with this ]

the HD-audio controller driver gets runtime-suspended, HD-audio link
is turned off, and the hotplug notification is ignored. This leads to
the inconsistent audio state (the connection isn't notified and ELD is
ignored).
The best fix would be to implement the proper ELD notification via the
audio component, but it's still not ready. As a quick workaround,
this patch adds the check of runtime_idle and allows the runtime
suspend only when the vga_switcheroo is bound with discrete GPU.
That is, a system with a single GPU and APU would be again without
runtime PM to keep the HD-audio link for the hotplug notification and
ELD read out.
Also, the codec->auto_runtime_pm flag is set only for the discrete GPU
at the time GPU gets bound via vga_switcheroo (i.e. only dGPU is
forcibly runtime-PM enabled), so that APU can still get the ELD
notification.
For identifying which GPU is bound, a new vga_switcheroo client
callback, gpu_bound, is implemented. The vga_switcheroo simply calls
this when GPU is bound, and tells whether it's dGPU or APU.

Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which
1) sets bus->chip_init to prevent multiple entrances before device
is stopped; 2) enables interrupt.
We shouldn't use it for the purpose of resetting device only because
1) when we really want to initialize device, we won't be able to do
so; 2) we are ready to handle interrupt yet, and kernel crashes when
interrupt comes in.
Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset
device properly.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for you net tree:
1) Remove duplicated include at the end of UDP conntrack, from Yue Haibing.
2) Restore conntrack dependency on xt_cluster, from Martin Willi.
3) Fix splat with GSO skbs from the checksum target, from Florian Westphal.
4) Rework ct timeout support, the template strategy to attach custom timeouts
is not correct since it will not work in conjunction with conntrack zones
and we have a possible free after use when removing the rule due to missing
refcounting. To fix these problems, do not use conntrack template at all
and set custom timeout on the already valid conntrack object. This
fix comes with a preparation patch to simplify timeout adjustment by
initializating the first position of the timeout array for all of the
existing trackers. Patchset from Florian Westphal.
5) Fix missing dependency on from IPv4 chain NAT type, from Florian.
6) Release chain reference counter from the flush path, from Taehee Yoo.
7) After flushing an iptables ruleset, conntrack hooks are unregistered
and entries are left stale to be cleaned up by the timeout garbage
collector. No TCP tracking is done on established flows by this time.
If ruleset is reloaded, then hooks are registered again and TCP
tracking is restored, which considers packets to be invalid. Clear
window tracking to exercise TCP flow pickup from the middle given that
history is lost for us. Again from Florian.
8) Fix crash from netlink interface with CONFIG_NF_CONNTRACK_TIMEOUT=y
and CONFIG_NF_CT_NETLINK_TIMEOUT=n.
9) Broken CT target due to returning incorrect type from
ctnl_timeout_find_get().
10) Solve conntrack clash on NF_REPEAT verdicts too, from Michal Vaner.

After merging the iolatency policy, we potentially now have 4 policies

Commit 1c892e38ce59 ("regulator: da9063: Handle less LDOs on DA9063L")
reordered the da9063_regulator_info[] array, but not the DA9063_ID_*
regulator ids and not the da9063_matches[] array, because ids are used
as indices in the array initializer. This mismatch between regulator id
and da9063_regulator_info[] array index causes the driver probe to fail
because constraints from DT are not applied to the correct regulator:
da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50)
DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV

DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22)
This patch reorders the DA9063_ID_* as apparently intended, and with
them the entries in the da90630_matches[] array.

Pull tracing fixes from Steven Rostedt:
"This fixes two annoying bugs:
- The first one is a side effect caused by using SRCU for rcuidle
tracepoints. It seems that the perf was depending on the rcuidle
tracepoints to make RCU watch when it wasn't.
The real fix will be to have perf use SRCU instead of depending on
RCU watching, but that can't be done until SRCU is safe to use in
NMI context (Paul's working on that).
- The second bug fix is for a bug that's been periodically making my
tests fail randomly for some time. I haven't had time to track it
down, but finally have. It has to do with stressing NMIs (via perf)
while enabling or disabling ftrace function handling with lockdep
enabled.
If an interrupt happens and just as it returns, it sets lockdep
back to "interrupts enabled" but before it returns an NMI is
triggered, and if this happens while printk_nmi_enter has a
breakpoint attached to it (because ftrace is converting it to or
from nop to call fentry), the breakpoint trap also calls into
lockdep, and since returning from the NMI to a interrupt handler,
interrupts were disabled when the NMI went off, lockdep keeps its
state as interrupts disabled when it returns back from the
interrupt handler where interrupts are enabled.
This causes lockdep_assert_irqs_enabled() to trigger a false
positive"

When the mlx5 health mechanism detects a problem while the driver
is in the middle of init_one or remove_one, the driver needs to prevent
the health mechanism from scheduling future work; if future work
is scheduled, there is a problem with use-after-free: the system WQ
tries to run the work item (which has been freed) at the scheduled
future time.
Prevent this by disabling work item scheduling in the health mechanism
when the driver is in the middle of init_one() or remove_one().

This is due to the tracepoints moving to SRCU usage which does not require
RCU to be "watching". But perf uses these tracepoints with RCU and expects
it to be. Hence, we still need to add in the rcu_irq_enter/exit_irqson()
calls for "rcuidle" tracepoints. This is a temporary fix until we have SRCU
working in NMI context, and then perf can be converted to use that instead
of normal RCU.

Since this header is in "include/uapi/linux/", apparently people want to
use it in userspace programs -- even in C++ ones. However, the header
uses a C++ reserved keyword ("private"), so change that to "dh_private"

commit f07b3c1da92d ("HID: generic: create one input report per

hidinput->report was never set, so hidinput_match_application()

Fix that by testing against the real application.
Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
