      qemu: Use ULL instead of uint64_t for RDMA GID event · f8862714
      由 Michal Privoznik 提交于 
      In the previous commit we are using uint64_t for storing subnet
prefix and interface id that qemu reports in
RDMA_GID_STATUS_CHANGED event. We also report them in some debug
messages. This poses a problem because uint64_t can be UL or ULL
depending on the host architecture and hence we wouldn't know
which format to use. Switch to ULL which is big enough and
doesn't suffer from the issue.

      qemu: Process RDMA GID state change event · ed357cef
      由 Yuval Shaia 提交于 
      This event is emitted on the monitor when a GID table in pvrdma device
is modified and the change needs to be propagate to the backend RDMA
device's GID table.

The control over the RDMA device's GID table is done by updating the
device's Ethernet function addresses.
Usually the first GID entry is determine by the MAC address, the second
by the first IPv6 address and the third by the IPv4 address. Other
entries can be added by adding more IP addresses. The opposite is the
same, i.e. whenever an address is removed, the corresponding GID entry
is removed.

The process is done by the network and RDMA stacks. Whenever an address
is added the ib_core driver is notified and calls the device driver's
add_gid function which in turn update the device.

To support this in pvrdma device we need to hook into the create_bind
and destroy_bind HW commands triggered by pvrdma driver in guest.
Whenever a changed is made to the pvrdma device's GID table a special
QMP messages is sent to be processed by libvirt to update the address of
the backend Ethernet device.

      Enforce a standard header file guard symbol name · 568a4172
      由 Daniel P. Berrangé 提交于 
      Require that all headers are guarded by a symbol named

  LIBVIRT_$FILENAME

where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.

Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

      Fix many mistakes & inconsistencies in header file layout · 4cfd7090
      由 Daniel P. Berrangé 提交于 
      This introduces a syntax-check script that validates header files use a
common layout:

  /*
   ...copyright header...
   */
  <one blank line>
  #ifndef SYMBOL
  # define SYMBOL
  ....content....
  #endif /* SYMBOL */

For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:

  #ifndef SYMBOL_ALLOW
  # error ....
  #endif /* SYMBOL_ALLOW */
  <one blank line>

The many mistakes this script identifies are then fixed.

      Remove all Author(s): lines from source file headers · 60046283
      由 Daniel P. Berrangé 提交于 
      In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

      qemu: Add monitor functions to set IOThread params · 3083bf18
      由 John Ferlan 提交于 
      Add functions to set the IOThreadInfo param data for the live guest.
Modify the _qemuMonitorIOThreadInfo to have a flag to indicate when
a value was set so that we don't set a value unless it was desired
to be set.

Based on code originally posted by Pavel Hrdina <phrdina@redhat.com>,
but extracted into a separate patch. Note that qapi expects to receive
integer parameters rather than unsigned long long or unsigned int's.
QEMU does save the value in larger signed 64 bit values eventually.

      qemu: Check for and return IOThread polling values if available · d1c1f2c2
      由 John Ferlan 提交于 
      If there are IOThread polling values in the query-iothreads return
buffer, then fill them in and set a bool indicating their presence.
This will allow for displaying in a domain stats output eventually.

Note that the QEMU values are managed a bit differently (as int's
stored in int64_t's) than we will manage them (as unsigned long and
int values). This is intentional to allow for value validation
checking when it comes time to provide the values to QEMU.

      qemu: don't retry connect() if doing FD passing · 7ef0471b
      由 Daniel P. Berrangé 提交于 
      Since libvirt called bind() and listen() on the UNIX socket, it is
guaranteed that connect() will immediately succeed, if QEMU is running
normally. It will only fail if QEMU has closed the monitor socket by
mistake or if QEMU has exited, letting the kernel close it.

With this in mind we can remove the retry loop and timeout when
connecting to the QEMU monitor if we are doing FD passing. Libvirt can
go straight to sending the QMP greeting and will simply block waiting
for a reply until QEMU is ready.
