fdc: Reject clash between -drive if=floppy and -global isa-fdc The floppy controller devices desugar their drive properties into floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to FloppyDrive", v2.8.0). This involves some bad magic in fdctrl_connect_drives(), and exists for backward compatibility. The functions for boards to create floppy controller devices fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init() desugar -drive if=floppy to these floppy controller drive properties. If you use both -drive if=floppy (or its -fda / -fdb sugar) and -global isa-fdc for the same floppy device, -global silently loses the conflict, and both backends involved end up with the floppy device frontend attached, as demonstrated by iotest 172 (see commit before previous). This is wrong. Desugar -drive if=floppy straight to floppy devices instead, with helper fdctrl_init_drives(). The conflict now gets rejected cleanly: first, fdctrl_connect_drives() creates the floppy for the controller's property, then fdctrl_init_drives() attempts to create the floppy for -drive if=floppy, but fails because the unit is already in use. Output of iotest 172 changes in three ways: 1. The clash gets rejected. 2. In one test case, "info qtree" has the floppy devices swapped, and "info block" has their QOM paths swapped. This is because the floppy device for -fda now gets created after the one for -global isa-fdc.driveB. 3. The error message for -global floppy.drive=floppy0 changes. Before the patch, we set isa-fdc.driveA to -fda's block backend, then create the floppy device for it, then move the backend from isa-fdc.driveA to floppy.drive. Floppy creation fails when applying -global floppy.drive=floppy0, because floppy0 is still attached to isa-fdc. After the patch, we create the floppy for -fda, then set its drive property to floppy0. Now floppy creation succeeds, but setting the drive property fails, because -global already set it. Yes, this is exasperatingly complicated.

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().
