ACK 63ca568
- The new name of cs_addrLocal -> m_addr_local_mutex is an improvement.
- I checked that
m_addr_local_mutexis being used at two places in the codebase. These instances have been addressed by Asserting Lock not held before locking the mutex. So I think it's safe to convertm_addr_local_mutexfrom RecursiveMutex to Mutex.

Concept ACK.
Adding AssertLockNotHeld(m_addr_local_mutex) macros should be combined with adding thread safety annotations LOCKS_EXCLUDED(m_addr_local_mutex) in the src/net.h. See https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#threads-and-synchronization
Also, for the safe commit history, "refactor: replace RecursiveMutex m_addr_local_mutex with Mutex" commit should follow "p2p: add assertions for m_addr_local_mutex" one.

reACK dec787d
Changes since my last review:
- Added Thread Safety annotation,
LOCKS_EXCLUDED(m_addr_local_mutex), to theGet/Set AddrLocal()functions' declaration. - Rearranged commits so that
m_addr_local_mutexis converted to Mutex, after, other conditions are made right for it.
