Re: [libvirt PATCH] json: do not call json_tokener_free with NULL

Add an error message for the rare case if json_tokener_new fails (allocation failure) and guard any use of json_tokener_free where tok might be NULL (this was possible in libvirt-nss when the json file could not be opened). https://gitlab.com/libvirt/libvirt/-/issues/581 Signed-off-by: Ján Tomko <jtomko(a)redhat.com&gt; Reported-by: Simon Pilkington --- src/util/virjson.c | 8 +++++++- tools/nss/libvirt_nss_leases.c | 7 ++++++- tools/nss/libvirt_nss_macs.c | 7 ++++++- 3 files changed, 19 insertions(+), 3 deletions(-)
