If a db resize happened, the txpool meta cursor might be stale,
and was not being renewed when necessary.
It would cause this SEGSEGV:
in mdb_cursor_set ()
in mdb_cursor_get ()
in cryptonote::BlockchainLMDB::get_txpool_tx_blob(crypto::hash const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, cryptonote::relay_category) const ()
in cryptonote::tx_memory_pool::get_transaction(crypto::hash const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, cryptonote::relay_category) const ()
in cryptonote::t_cryptonote_protocol_handler<cryptonote::core>::handle_notify_new_fluffy_block(int, epee::misc_utils::struct_init<cryptonote::NOTIFY_NEW_FLUFFY_BLOCK::request_t>&, cryptonote::cryptonote_connection_context&) ()
During the handshake for an incoming connection, the peer id is checked against the local node's peer id only for the specific zone of the incoming peer, in order to avoid linking public addresses to tor addresses:
5d7ae2d279/src/p2p/net_node.inl (L2343)
However, on handshakes for outgoing connections, all zones are checked:
5d7ae2d279/src/p2p/net_node.inl (L1064)
If an attacker wanted to link a specific tor node to a public node, they could potentially connect to as many public nodes as possible, get themselves added to the peer whitelist, maybe stuff some more attacker-owned addresses into the greylist, then disconnect, and for any future incoming connections, respond with the tor node's id in an attempt to link the public/tor addresses.
- Finding handling function in ZMQ JSON-RPC now uses binary search
- Temporary `std::vector`s in JSON output now use `epee::span` to
prevent allocations.
- Binary -> hex in JSON output no longer allocates temporary buffer
- C++ structs -> JSON skips intermediate DOM creation, and instead
write directly to an output stream.

From the FreeBSD architecture handbook (https://www.freebsd.org/doc/en/books/arch-handbook/jail-restrictions.html) as it relates to `allow.sysvipc`, "By default, this sysctl is set to 0. If it were set to 1, it would defeat the whole purpose of having a jail; privileged users from the jail would be able to affect processes outside the jailed environment." This is undesirable behavior.
Per `man jail`, regarding `allow.sysvipc`, "A process within the jail has access to System V primitives. This is deprecated in favor of the per-module parameters."
Since FreeBSD 11, the new way to deal with this (the per-module parameters) is with: `sysvshm`, for shared memory, `sysvsem`, for semaphores, and `sysvmsg`, for message queues. These can be set selectively to either `disable`; `inherit`, for the previous behavior (problematic due to UID collision, apparently); and `new`, for new behavior that avoids the UID collision problem.
Monero only uses semaphores, therefore we should recommend that jails be run with `sysvsem="new"` in the jail's jail.conf. Tested on FreeBSD 12.1.
Also, Monero is now able to be downloaded as a package or built from ports as `monero-cli` with a versioned suffix. It's got `Monero 'Carbon Chamaeleon' (v0.15.0.1-release)` as of right now, and it's been there 2-3 months, meaning it's currently and timely.
