#     keys, dns: Fix size check of V1 server-list header
#     
#     Fix the size check added to dns_resolver_preparse() for the V1 server-list
#     header so that it doesn't give EINVAL if the size supplied is the same as
#     the size of the header struct (which should be valid).
#     
#     This can be tested with:
#     
#             echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p
#     
#     which will give "add_key: Invalid argument" without this fix.
#     
#     Fixes: 1997b3cb4217 ("keys, dns: Fix missing size check of V1 server-list header")
