• Fix up credit charge calculation which causes a STATUS_INVALID_PARAMETER response for certain read/write lengths
• Ensure responses with a failure are cleaned up from the outstanding request table to avoid memory leaks

1.5.1 - 2021-05-08

• Unified DFS path handling when using any API that uses a transaction to open the file
  • This includes smbclient.rename and smbclient.replace
• Fixed up smbclient.rename to work with directories
• smbclient.scandir will continue to use the connection cache when getting stat information of a dir entry

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

v1.4.0

1.4.0 - 2021-02-02

• Fixed up secure negotiation logic when connecting to older SMB dialects
• Will attempt to perform secure negotiation even on older dialects that may not implement it properly

• Changed initial credit request from 256 to 64 when creating the SMB session
  • This is done to avoid overloading the SMB server
  • If smbclient requires more credits to perform an operation it will request it automatically
• Improve credit handling when reading and writing large amounts of data to reduce the number of requests being made
• Fixed up write() in smbclient.open_file() to be able to write bytes greater than the max_write_size
• Fixed issue when receiving an unknown NtStatus error code from the server
• Added PipeBusy exception for STATUS_PIPE_NOT_AVAILABLE 0xC00000AD error responses
• Fix credit granting calculation when receiving a compound response
  • Original logic granted len(responses) - 1 credits than what the server actually given causing errors when the client ran out of credits without it knowing
• Added auth_protocol to Session, ClientConfig, and register_session() to control what authentication protocol is used
  • This can be negotiate (default), kerberos, or ntlm where negotiate selects kerberos or ntlm depending on what's available
