Merge #11655: net: Assert state.m_chain_sync.m_work_header in ConsiderEviction
63c2d83 Explicitly state assumption that state.m_chain_sync.m_work_header != nullptr in ConsiderEviction (practicalswift)
Pull request description:
Explicitly state assumption that `state.m_chain_sync.m_work_header != nullptr` in `ConsiderEviction(…)`.
Static analyzer (and humans!) will see the null-check in ...
```
else if (state.m_chain_sync.m_timeout == 0 || (state.m_chain_sync.m_work_header != nullptr && ...
```
... and infer that `state.m_chain_sync.m_work_header` might be set to `nullptr` when reaching `else if (state.m_chain_sync.m_timeout > 0 && time_in_seconds > state.m_chain_sync.m_timeout)` and thus flag `state.m_chain_sync.m_work_header->GetBlockHash().ToString()` as a potential null pointer dereference.
This commit makes the tacit assumption of `state.m_chain_sync.m_work_header != nullptr` explicit.
Code introduced in 5a6d00c6defc587e22c93e63029fdd538ce8858d ("Permit disconnection of outbound peers on bad/slow chains") which was merged into master four days ago.
Friendly ping @sdaftuar :-)
