| 1 | The .mmdb files and GeoIP2-Country-Test.json are MaxMind's published test |
| 2 | data from github.com/maxmind/MaxMind-DB, dual licensed MIT or Apache-2.0 |
| 3 | (LICENSE-MIT, LICENSE-APACHE beside this file). All were fetched at commit |
| 4 | 276926d23b4109ca5452709bfb5931c338afb34c. They contain test records only, not real geolocation data. |
| 5 | `pathological-dag.mmdb` is not MaxMind's: a 32-node IPv4 tree whose two |
| 6 | children are both the next node (2^32 network paths), built for the geoip |
| 7 | code review R8-1 regression. It must be refused by `OpenMMDBVerified`. |
| 8 | `pathological-empty-dag.mmdb` is a 128-node IPv6 tree whose children share |
| 9 | the next node and end in the empty sentinel: maxminddb's walk spends 2^128 |
| 10 | steps inside one call. `pathological-metadata.mmdb` declares node_count |
| 11 | 2^63, which overflows the library's own arithmetic and panics it. Both are |
| 12 | for the geoip code review R9 regressions: only the console's verifier |
| 13 | child may ever open them. |
| 14 | `pathological-bigmap.mmdb` has one data record declaring a map of |
| 15 | 16,843,036 entries: maxminddb allocates it before noticing the entries are |
| 16 | missing. The verifier child's memory cap must contain it. |
