11 years agoadd timestamp to error_report()
Seiji Aguchi [Thu, 4 Jul 2013 03:02:46 +0000 (23:02 -0400)]
add timestamp to error_report()

[Issue]
When we offer a customer support service and a problem happens
in a customer's system, we try to understand the problem by
comparing what the customer reports with message logs of the
customer's system.

In this case, we often need to know when the problem happens.

But, currently, there is no timestamp in qemu's error messages.
Therefore, we may not be able to understand the problem based on
error messages.

[Solution]
Add a timestamp to qemu's error message logged by
error_report() with g_time_val_to_iso8601().

Fix -machine options accel, kernel_irqchip, kvm_shadow_mem

Multiple -machine options with the same ID are merged.  All but the
one without an ID are to be silently ignored.

In most places, we query these options with a null ID.  This is
correct.

In some places, we instead query whatever options come first in the
list.  This is wrong.  When the -machine processed first happens to
have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.

Example:

    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on
    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen
    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on

    $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on

    xen be core: can't open xen interface
    failed to initialize Xen: Operation not permitted

Option usb is queried correctly, and the one without an ID wins,
regardless of option order.

Option accel is queried incorrectly, and which one wins depends on
option order and ID.

Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.

Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given.  Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options.  Downstreams
that enable KVM by default do get bitten, though.

Use qemu_get_machine_opts() to fix these bugs.

qemu-option: Fix qemu_opts_set_defaults() for corner cases

Commit 4f6dd9a changed the initialization of opts in opts_parse() to
this:

    if (defaults) {
        if (!id && !QTAILQ_EMPTY(&list->head)) {
            opts = qemu_opts_find(list, NULL);
        } else {
            opts = qemu_opts_create(list, id, 0);
        }
    } else {
        opts = qemu_opts_create(list, id, 1);
    }

Same as before for !defaults.

If defaults is true, and params has no ID, and options exist, we use
the first assignment.  It sets opts to null if all options have an ID.
opts_parse() then returns null.  qemu_opts_set_defaults() asserts the
value is non-null.  It's the only caller that passes true for
defaults.

To reproduce, try "-M xenpv -machine id=foo" (yes, "id=foo" is silly,
but it shouldn't crash).

I believe the function attempts to do the following:

    If options don't yet exist, create new options
    Else, if defaults, modify the existing options
    Else, if list->merge_lists, modify the existing options
    Else, fail

A straightforward call of qemu_opts_create() does exactly that.

11 years agopci: Replace pci_find_domain() with more general pci_root_bus_path()
David Gibson [Thu, 6 Jun 2013 08:48:49 +0000 (18:48 +1000)]
pci: Replace pci_find_domain() with more general pci_root_bus_path()

pci_find_domain() is used in a number of places where we want an id for a
whole PCI domain (i.e. the subtree under a PCI root bus).  The trouble is
that many platforms may support multiple independent host bridges with no
hardware supplied notion of domain number.

This patch, therefore, replaces calls to pci_find_domain() with calls to
a new pci_root_bus_path() returning a string.  The new call is implemented
in terms of a new callback in the host bridge class, so it can be defined
in some way that's well defined for the platform.  When no callback is
available we fall back on the qbus name.

Most current uses of pci_find_domain() are for error or informational
messages, so the change in identifiers should be harmless.  The exception
is pci_get_dev_path(), whose results form part of migration streams.  To
maintain compatibility with old migration streams, the PIIX PCI host is
altered to always supply "0000" for this path, which matches the old domain
number (since the code didn't actually support domains other than 0).

For the pseries (spapr) PCI bridge we use a different platform-unique
identifier (pseries machines can routinely have dozens of PCI host
bridges).  Theoretically that breaks migration streams, but given that we
don't yet have migration support for pseries, it doesn't matter.

Any other machines that have working migration support including PCI
devices will need to be updated to maintain migration stream compatibility.

correctly using the FSR value which the kernel passes us in the
error_code field of uc_mcontext. Since the WnR bit of the FSR was
only introduced in ARMv6, this means that v5 cores will continue
to behave as before this patch, but they are not really supported
as hosts for linux-user mode anyway since they do not have the
modern behaviour for unaligned accesses.

11 years agolinux-user: Fix sys_utimensat (would not compile on old glibc)

linux-user: Fix sys_utimensat (would not compile on old glibc)

Commit c0d472b12e accidentally dropped the definition of
__NR_SYS_utimensat even though its use is guarded by
CONFIG_UTIMENSAT, not CONFIG_ATFILE. Some older glibc don't
have utimensat() (even if they have the other *at() functions).
Fix this by correctly cleaning up the sys_utimensat()
implementation and #defines, so that we always provide the
syscall if needed whether we're doing it via glibc or not.

linux-user: fix signal number range check

When translating between host and target signal numbers keep negative
numbers unchanged, avoiding access beyond array bounds.
