Module Tezos_p2p.P2p_acl
Source
This module implements four Access Control Lists:
- IP greylist is a set of banned IP addresses automatically added by the P2P layer.
peer_id
greylist is a set of banned peers ids automatically added by the P2P layer.
- IP blacklist is a set of IP addresses manually added by the node admin.
- peers blacklist is a set of peers ids manually added by the node admin.
IP greylists use a time based GC to periodically remove entries from the table, while peer_id
greylists are built using an LRU cache, where the least-recently grey-listed peer is evicted from the table when adding a new banned peer to a full cache. Other tables are user defined and static.
val create :
peer_id_size:int ->
ip_size:int ->
ip_cleanup_delay:Tezos_base.TzPervasives.Time.System.Span.t ->
t
create ~peer_id_size ~ip_size
is a set of four ACLs (see above) with the peer_id greylist being a LRU cache of size peer_id_size
and the IP address greylist a bloom filter of size ip_size
(expressed in KiB). Elements are (probabilistically) kept in the bloom filter for ip_cleanup_delay
, the cleanup happens in a discrete way in sixteen steps.
banned_addr t addr
is true
if addr
is blacklisted or greylisted.
unban_addr t addr
remove the address from both the blacklist of banned addresses and the greylist of addresses
banned_peer t peer_id
is true
if peer with id peer_id
is blacklisted or greylisted.
unban_peer t peer
remove the peer from both the blacklist of banned peers and the greylist of peers
