-    p2p: add 0 port check in dialer  (#21008)
-    
-    * p2p: add low port check in dialer
-    
-    We already have a check like this for UDP ports, add a similar one in
-    the dialer. This prevents dials to port zero and it's also an extra
-    layer of protection against spamming HTTP servers.
-    
-    * p2p/discover: use errLowPort in v4 code
-    
-    * p2p: change port check
-    
-    * p2p: add comment
-    
-    * p2p/simulations/adapters: ensure assigned port is in all node records

-    core/rawdb: stop freezer process as part of freezer.Close() (#21010)
-    
-    * core/rawdb: Stop freezer process as part of freezer.Close()
-    
-    When you call db.Close(), it was closing the leveldb database first,
-    then closing the freezer, but never stopping the freezer process.
-    This could cause the freezer to attempt to write to leveldb after
-    leveldb had been closed, leading to a crash with a non-zero exit code.
-    
-    This change adds a quit channel to the freezer, and freezer.Close()
-    will not return until the freezer process has stopped.
-    
-    Additionally, when you call freezerdb.Close(), it will close the
-    AncientStore before closing leveldb, to ensure that the freezer goroutine
-    will be stopped before leveldb is closed.
