Subject: [PATCH] network: make it safe to call networkSetupPrivateChains()
|
|
multiple times

|
|
|
|
networkSetupPrivateChains() is currently called only once per run of
|
|
libvirtd, so it can assume that errInitV4 and errInitV6 are empty/null
|
|
when it is called. In preparation for potentially calling this
|
|
function multiple times during one run, this patch moves the reset of
|
|
errInitV[46] to the top of the function, to assure no memory is
|
|
leaked.
