5 years agosmbios: Encode UUID according to SMBIOS specification
Eduardo Habkost [Wed, 29 Oct 2014 13:26:08 +0000 (11:26 -0200)] 
smbios: Encode UUID according to SMBIOS specification

Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

> Although RFC 4122 recommends network byte order for all fields, the PC
> industry (including the ACPI, UEFI, and Microsoft specifications) has
> consistently used little-endian byte encoding for the first three fields:
> time_low, time_mid, time_hi_and_version. The same encoding, also known as
> wire format, should also be used for the SMBIOS representation of the UUID.
>
> The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
> as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.

The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b9e36887e119589d456557d72ab37b5.

Change smbios_build_type_1_table() to encode the UUID as specified.

To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):

  machine_parse()
    object_class_get_list(TYPE_MACHINE)
      object_class_foreach()
        g_hash_table_foreach()

The current order is a "random" one, for practical purposes, which is
annoying for users.

Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.

The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
  order,
- sorts machine types inside the same family in alphabetically decreasing
  order,
- sorts standalone machine types between each other in alphabetically
  increasing order.

After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

5 years agosmbios: Fix assertion on socket count calculation
Eduardo Habkost [Tue, 30 Sep 2014 01:21:45 +0000 (22:21 -0300)] 
smbios: Fix assertion on socket count calculation

QEMU currently allows the number of VCPUs to not be a multiple of the
number of threads per socket, but the smbios socket count calculation
introduced by commit c97294ec1b9e36887e119589d456557d72ab37b5 doesn't
take that into account, triggering an assertion. e.g.:

  $ ./x86_64-softmmu/qemu-system-x86_64 -smp 4,sockets=2,cores=6,threads=1
  qemu-system-x86_64: /home/ehabkost/rh/proj/virt/qemu/hw/i386/smbios.c:825: smbios_get_tables: Assertion `smbios_smp_sockets >= 1' failed.
  Aborted (core dumped)

Socket count calculation doesn't belong to smbios.c and should
eventually be moved to the main SMP topology configuration code. But
while we don't move the code, at least make it correct by rounding up
the division.

The virtio-rng backend is currently linked twice, once in the proxy

a double unref of the backend when the parent device is unplugged.

Ray Strode [Sun, 19 Oct 2014 02:12:48 +0000 (22:12 -0400)] 
libcacard: Lock NSS cert db when selecting an applet on an emulated card

When a process in a guest uses an emulated smartcard, libcacard running
on the host passes the PIN from the guest to the PK11_Authenticate NSS
function. The first time PK11_Authenticate is called the passed in PIN
is used to unlock the certificate database. Subsequent calls to
PK11_Authenticate will transparently succeed, regardless of the passed in
PIN. This is a convenience for applications provided by NSS.

Of course, the guest may have many applications using the one emulated
smart card all driven from the same host QEMU process.  That means if a
user enters the right PIN in one program in the guest, and then enters the
wrong PIN in another program in the guest, the wrong PIN will still
successfully unlock the virtual smartcard.

This commit forces the NSS certificate database to be locked anytime an
applet is selected on an emulated smartcard by calling vcard_emul_logout.

get_maintainer.pl: restrict cases where it falls back to --git

The list emitted by --git-fallback often leads inexperienced contributors
to add pointless CCs.  While not discouraging usage of --git-fallback,
we want to:

1) disable the fallback if only some files lack a maintainer

    $ scripts/get_maintainer.pl -f util/cutils.c hw/ide/core.c
    Kevin Wolf <kwolf@redhat.com> (odd fixer:IDE)
    Stefan Hajnoczi <stefanha@redhat.com> (odd fixer:IDE)

This behavior is taken even if --git-fallback is specified.

2) warn the contributors about what we're doing, asking them to use their
common sense:

    $ scripts/get_maintainer.pl -f util/cutils.c
    get_maintainer.pl: No maintainers found, printing recent contributors.
    get_maintainer.pl: Do not blindly cc: them on patches!  Use common sense.

    Luiz Capitulino <lcapitulino@redhat.com> (commit_signer:1/2=50%)

Explicitly disabling the fallback will not result in the warning message:

    $ scripts/get_maintainer.pl -f util/cutils.c   --no-git-fallback
    $ echo $?
    0

(Returning 1 would break usage of scripts/get_maintainer.pl as a cccmd
for git-send-email).
