2015-06-12throttle: acquire the ThrottleGroup lock in bdrv_swap()Alberto Garcia
bdrv_swap() touches the fields of a BlockDriverState that are protected by the ThrottleGroup lock. Although those fields end up in their original place, they are temporarily swapped in the process, so there's a chance that an operation on a member of the same group happening on a different thread can try to use them.

2015-06-12throttle: Add throttle group supportAlberto Garcia
The throttle group support use a cooperative round robin scheduling algorithm. The principles of the algorithm are simple: - Each BDS of the group is used as a token in a circular way. - The active BDS computes if a wait must be done and arms the right timer. - If a wait must be done the token timer will be armed so the token will become the next active BDS.

2015-06-12throttle: Extract timers from ThrottleState into a separate structureBenoît Canet
Group throttling will share ThrottleState between multiple bs. As a consequence the ThrottleState will be accessed by multiple aio context. Timers are tied to their aio context so they must go out of the ThrottleState structure. This commit paves the way for each bs of a common ThrottleState to have its own timer.

2015-06-12Add a protective section footerDr. David Alan Gilbert
Badly formatted migration streams can go undetected or produce misleading errors due to a lock of checking at the end of sections. In particular a section that adds an extra 0x00 at the end causes what looks like a normal end of stream and thus doesn't produce any errors, and something that ends in a 0x01..0x04 kind of look like real section headers and then fail when the section parser tries to figure out which section they are. This is made worse by the choice of 0x00..0x04 being small numbers that are particularly common in normal section data. This patch adds a section footer consisting of a marker (0x7e - ~) followed by the section-id that was also sent in the header. If they mismatch then it throws an error explaining which section was being loaded.

2015-06-10fw_cfg: remove support for guest-side data writesGabriel L. Somlo
From this point forward, any guest-side writes to the fw_cfg data register will be treated as no-ops. This patch also removes the unused host-side API function fw_cfg_add_callback(), which allowed the registration of a callback to be executed each time the guest completed a full overwrite of a given fw_cfg data item.

Retain the function value for now, to permit selective conversion of its callers. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2015-06-09QemuOpts: Drop qemu_opt_foreach() parameter abort_on_failureMarkus Armbruster
When the argument is non-zero, qemu_opt_foreach() stops on callback returning non-zero, and returns that value. When the argument is zero, it doesn't stop, and returns the callback's value from the last iteration. The two callers that pass zero could just as well pass one: * qemu_spice_init()'s callback add_channel() either returns zero or exit()s. * config_write_opts()'s callback config_write_opt() always returns zero. Drop the parameter, and always stop. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
