Re: [PATCH] util: don't validate empty params

If there are no parameters, there is nothing to validate. If params == NULL, memcpy below results in memcpy(sorted, NULL, 0), which is UB. Found by UBSAN. Example of this codepath: virDomainBlockCopy() (where nparams == 0 is valid) -> qemuDomainBlockCopy() Signed-off-by: Oleg Vasilev <oleg.vasilev(a)virtuozzo.com&gt; --- src/util/virtypedparam.c | 4 ++++ 1 file changed, 4 insertions(+)
