| Subject: netfilter: nf_tables: set names cannot be larger than 15 bytes |
| |
| From: Pablo Neira Ayuso <pablo@netfilter.org> |
| |
| commit a9bdd8365684810e3de804f8c51e52c26a5eccbb upstream. |
| |
| Currently, nf_tables trims off the set name if it exceeeds 15 |
| bytes, so explicitly reject set names that are too large. |
