LTP syscalls keyctl05 failure was detected on -next (
4.19.0-rc6-next-20181005) and
reported to LTP mailing list.
Now we have seen this issues on -mainline kernel.

keyctl05 failure not a kernel bug instead test case "keyctl05" needs
to be updated according to the latest upstream changes.

Please find below discussion for more details.

I'm guessing it's
  dns: Allow the dns resolver to retrieve a server set
  https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/net/dns_resolver?id=bbb4c4323a4d9cb5ca04db904aa3050a7586839a
which added some additional checks.

Test currently uses 2 zeroes:

+        const struct dns_payload_header *bin;
...
+               if (datalen <= sizeof(*bin))
+                       return -EINVAL;

+struct dns_payload_header {
+       __u8            zero;           /* Zero byte: marks this as
not being text */
+       __u8            content;        /* enum dns_payload_content_type */
+       __u8            version;        /* Encoding version */
+} __packed;

and commit above appears to need 0x00 0x00 0x01 or 0xFF 0x00 to not
return EINVAL.
