v1.5.0

1.5.0 - 2021-03-25

• Added smbprotocol.exceptions.SMBConnectionClosed that is raised when trying to send or receive data on a connection that has been closed
• Added smbprotocol.exceptions.WrongPassword that is raised when some servers indicate the password is not correct or the account is locked out
• Do not attempt to reuse any cached connections that have been closed in smbclient
• Added a lock when writing to the socket, only 1 thread can write a message at a single point in time
• Revamped the SMB receiver code to simplify the logic and make it more durable
  • Removed the TCP recv thread for each connection, now each connection uses just 1 thread instead of 2
  • Be more defensive when reading data from a socket to ensure we get all the data we require
  • Handled server side FIN packets that close the connection unexpectedly, any requests waiting for a response will raise SMBConnectionClosed
