We generally assume that loosening permission restrictions can never fail. We have seen in the past that this assumption is wrong. This has led to crashes because we generally pass &error_abort when loosening permissions. However, a failure in such a case should actually be handled in quite the opposite way: It is very much not fatal, so qemu may report it, but still consider the operation successful. The only realistic problem is that qemu may then retain permissions and thus locks on images it actually does not require. But again, that is not fatal. To implement this behavior, we make all functions that change permissions and that pass &error_abort to the initiating function (bdrv_check_perm() or bdrv_child_check_perm()) evaluate the @loosen_restrictions value introduced in the previous patch. If it is true and an error did occur, we abort the permission update, discard the error, and instead report success to the caller. bdrv_child_try_set_perm() itself does not pass &error_abort, but it is the only public function to change permissions. As such, callers may pass &error_abort to it, expecting dropping permission restrictions to never fail. Signed-off-by: NMax Reitz <mreitz@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch makes three functions report whether the necessary permission change tightens restrictions or not. These functions are: - bdrv_check_perm() - bdrv_check_update_perm() - bdrv_child_check_perm() Callers can use this result to decide whether a failure is fatal or not (see the next patch).

We cannot use bdrv_child_try_set_perm() to give up all restrictions on the child edge, and still have bdrv_mirror_top_child_perm() request BLK_PERM_WRITE. Fix this by making bdrv_mirror_top_child_perm() return 0/BLK_PERM_ALL when we want to give up all permissions, and replacing bdrv_child_try_set_perm() by bdrv_child_refresh_perms(). The bdrv_child_try_set_perm() before removing the node with bdrv_replace_node() is then unnecessary. No permissions have changed since the previous invocation of bdrv_child_try_set_perm().

If a block node uses bdrv_child_try_set_perm() to change the permission it takes on its child, the result may be very short-lived. If anything makes the block layer recalculate the permissions internally, it will invoke the node driver's .bdrv_child_perm() implementation. The permission/shared permissions masks that returns will then override the values previously passed to bdrv_child_try_set_perm(). If drivers want a child edge to have specific values for the permissions/shared permissions mask, it must return them in .bdrv_child_perm(). Consequentially, there is no need for them to pass the same values to bdrv_child_try_set_perm() then: It is better to have a function that invokes .bdrv_child_perm() and calls bdrv_child_try_set_perm() with the result. This patch adds such a function under the name of bdrv_child_refresh_perms().

Drop remaining users of bs->job: 1. assertions actually duplicated by assert(!bs->refcnt) 2. trace-point seems not enough reason to change stream_start to return BlockJob pointer 3. Restricting creation of two jobs based on same bs is bad idea, as 3.1 Some jobs creates filters to be their main node, so, this check don't actually prevent creating second job on same real node (which will create another filter node) (but I hope it is restricted by other mechanisms) 3.2 Even without bs->job we have two systems of permissions: op-blockers and BLK_PERM 3.3 We may want to run several jobs on one node one day And finally, drop bs->job pointer itself.

We are going to remove bs->job pointer. Drop it's usage in blk_iostatus_reset. blk_iostatus_reset() has only two callers: 1. blk_attach_dev(). This doesn't have anything to do with jobs and attaching a new guest device won't solve any problem the job encountered, so no reason to reset the iostatus for the job. 2. qmp_cont().

Currently, struct Monitor mixes state that is only relevant for HMP, state that is only relevant for QMP, and some actually shared state. In particular, a MonitorQMP field is present in the state of any monitor, even if it's not a QMP monitor and therefore doesn't use the state. As a first step towards a clean separation between QMP and HMP, let MonitorQMP extend Monitor and create a MonitorQMP object only when the monitor is actually a QMP monitor. Some places accessed Monitor.qmp unconditionally, even for HMP monitors. They can't keep doing this now, so during the conversion, they are either changed to become conditional on monitor_is_qmp() or to assert() that they always get a QMP monitor.

Instead of mixing HMP and QMP monitors in the same function, separate the monitor creation function for both. While in theory, one could pass both MONITOR_USE_CONTROL and MONITOR_USE_READLINE before this patch and both flags would do something, readline support is tightly coupled with HMP: QMP never feeds its input to readline, and the tab completion function treats the input as an HMP command. Therefore, this configuration is useless. After this patch, the QMP path asserts that MONITOR_USE_READLINE is not set. The HMP path can be used with or without MONITOR_USE_READLINE, like before.
