Subject: [PATCH 83/83] UTIL: Suppress Coverity warning
|
|
|
|
We recently added this code:
|
|
if (domain_name != NULL
|
|
&& is_files_provider(find_domain_by_name(dom,
|
|
domain_name,
|
|
false)))
|
|
|
|
find_domain_by_name returns NULL if the domain_name can't be found. This
|
|
of course makes mostly sense for trusted domains that can appear and
|
|
disappear. And is_files_provider() didn't handle the situation where the
|
|
domain pointer was NULL and would directly dereference it.
|
|
|
|
This commit just adds a NULL check for the domain pointer so that
|
|
is_files_provider() returns 'false' if the domain pointer was NULL.
|
|
|
|
Another alternative might be to check the return value of
|
|
find_domain_by_name(), but I don't think it's worth the trouble.
