[libvirt] [PATCH 0/7] qemu: use domCaps for validation
I'm trying to remove some hurdles and pitfalls WRT extending domaincapabilities data. One issue is that it's too easy to add invalid data to it, or let the data become out of date. For example the first two patches of this series add <rng model=X> domcaps reporting. The logic to fill in the domcaps data from qemuCaps is nearly identical to the logic we use to validate rng->model in qemuDomainRNGDefValidate. If just those patches are added, and later a new qemu rng model was introduced, a future patch could easily miss updated domaincapabilities output. This series aims to set up a pattern to prevent these types of issues from sneaking in. A function virDomainCapsDeviceDefValidate is added which will use domcaps data to perform validation against a devicedef. The existing qemu <rng> model validation is moved there. This ensures that any future <rng> model additions, if they want to work in the qemu driver, effectively need to extend domaincapabilities as well. It's also theoretically useful for other drivers too. One issue is that at DomainDefValidate time we don't have domCaps handy, or any cache layer for domCaps assembling. Patch #4 adds a domCapsCache hashtable to the virQEMUCaps class for caching domCaps builds based on the full tuple of emulator+machine+arch+virttype. If qemuCaps need to be regenerated, the domCaps cache is wiped out for us so we don't need to worry about the data being stale, it's tied to the lifetime of a qemuCaps instance.

It is already being used at qemuConnectGetDomainCapabilities, making the flow easier to read. Perhaps something worth mentioning in the commit msg. Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com>

qemuCaps is tied to a binary on disk. domCaps is tied to a combo of binary+machine+arch+virttype values. For the qemu driver this almost entirely translates to a permutation of qemuCaps though Upcoming patches want to use the domCaps data store at XML validate time, but we need to cache the data so we aren't repeatedly regenerating it. Add a domCapsCache hash table to qemuCaps. This ensures that the domCaps cache is blown away whenever qemuCaps needs to be regenerated. Adjust virQEMUDriverGetDomainCapabilities to search the cache and add to it if we don't find a hit.

Nit: there is a 80+ char line at the start of virQEMUDriverSearchDomcaps, but I'm not sure if this is more like a "nice to have" rule or if it's enforced like in QEMU. Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com>

At first I was affraid, I was petrified, that we will need to invalidate this cache whenever corresponding qemuCaps is invalidated. But that should be done automatically, because virQEMUCapsCacheLookup() unrefs qemuCaps when if finds outdated capabilities. Might be worth mentioning in the commit message. Or not. Your call. Michal

The qemu driver already does some <rng> model validation, based on qemuCaps. However, the logic for exposing <rng> model values in domcaps is basically identical. This drops the qemuCaps checking and compares against the domCaps data directly. This approach makes it basically impossible to add a new <rng> model to the qemu driver without extending domcaps. The validation can also be shared with other drivers eventually.

Tried the patch series. Unfortunately I didn't get the <rng> element reported in virsh capabilities, however I am not sure if this hardware (Lenovo T480) has a hardware RNG device to report anyways. I'll check it later when I have the chance. It is worth noticing that patch 3 is conflicting with current master. Extra code in qemu_driver.c that shifted the lines that the patch is changing (trivial) and, in qemu_conf.c, I had to change the call to virQEMUCapsFillDomainCaps since it is now taking an extra argument (added by 5b9819eedc).

Sorry for delayed review.
So I completely forgot about this series and never even saw the ACKs! I rebased the patches and they applied cleanly besides the driver->privileged piece that was already mentioned. So I addressed all the original review comments, add RB tags for you and Daniel, and pushed now. So no worries on the review delay :) Thanks, Cole
