[libvirt] [PATCH v2 0/4] cleanup resolving persistent/running/current flags
by Nikolay Shirokovskiy
Original name of series was:
Subject: [PATCH 0/3] make virDomainObjGetPersistentDef return only persistent definition
Changes from version1
=====================
Original motivation of the series was fixing virDomainObjGetPersistentDef so
that it would not return configs other than persistent. However the final patch
that does it in the first version is absent in current version. I think the
fix should be done another way and in different series. Thus this version has
only misc cleanups which are better splitted into patches in this version.
A few words why I leave patch for virDomainObjGetPersistentDef. First I should
not return NULL from the function as this value already has different meaning
- memory allocation error and there is code that checks for this error. This
code calls virDomainObjGetPersistentDef unconditionally but later use the
return value only for persistent domains, thus it could get NULL pointer on
function call and treat it as an allocation error.
I think the proper way would be chaning virDomainObjGetPersistentDef so it
could not fail that is not call virDomainObjSetDefTransient. Looks like this
is already true because drivers that distiguish between running/persistent
config call virDomainObjSetDefTransient ealy in the domain start process (and
even two times) so that later calls for virDomainObjSetDefTransient are
unnecessary.

[libvirt] [PATCH 0/7] Couple of -Os fixes

So while trying to bring down the size of my nss module, one of the things I've

are the fixes. If you think I should squash some patches together, I will
gladly do that.

[libvirt] [PATCH] daemon: fixup refcounting in close callback handling
by Nikolay Shirokovskiy
remoteDispatchConnectCloseCallbackRegister introduced in
f484310add53ebdc26a6fdcb88bc398750325b7e has problems. It refcounts
network client object and in case of NOOP driver operations
for close callback registering/unregistering (any driveres besides
vz) nobody will unref it later. As a result client connection
will not be disposed and driver connection will not be closed.
The fix is easy. We don't need to refcount at all. We don't get
dangling pointer because in remoteClientFreeFunc which is called
upon disposing this network client object we unregistering close
callback.
