@node Assuan
@appendix Description of the Assuan protocol.
@cindex Assuan, IPC
The architecture of the modular GnuPG system is based on a couple of
highly specialized modules which make up a network of client server
communication. A common framework for intermodule communication is
therefore needed and should be implemented in a library.
@appendixsubsec Goals
@itemize @bullet
@item Common framework for module communication
@item Easy debugging
@item Easy module testing
@item Extendible
@item Optional authentication and encryption facility
@item Usable to access external hardware
@end itemize
@appendixsubsec Design criteria
@itemize @bullet
@item Client Server with back channel
@item Use a mainly text based protocol
@item Escape certain control characters
@item Allow indefinite data length
@item Request confidentiality for parts of the communication
@item Dummy module should allow direct linking of client and server.
@item Inline data or descriptor passing for bulk data
@item No protection against DoS needed
@item Subliminal channels are not an issue
@end itemize
@appendixsubsec Implementation
@noindent
The implementation is line based with a maximum line size of 1000
octects. The default IPC mechanism are Unix Domain Sockets.
On a connect request the server responds either with an okay or an error
status. For authentication check the server may send an Inquiry
Response prior to the first Okay, it may also issue Status messages.
The server must check that the client is allowed to connect, this is
done by requesting the credentials for the peer and comparing them to
those of the server. This avoids attacks based on wrong socket
permissions.
It may choose to delay the first response in case of an error. The
server never closes the connection - however the lower protocol may do
so after some time of inactivity or when the connection is in an error
state.
All textual messages are assumed to be in UTF-8 unless otherwise noted.
@appendixsubsec Server responses
@table @code
@item OK [<arbitary debugging information>]
Request was successful.
@item ERR @var{errorcode} [<human readable error description>]
Request could not be fulfilled. The error codes are mostly application
specific except for a few common ones.
@item S @var{keyword} <status information depending on keyword>
Informational output by the server, still processing the request.
@item # <string>
Comment line issued only for debugging purposes. Totally ignored.
@item D <raw data>
Raw data returned to client. There must be exactly one space after the
'D'. The values for '%', CR and LF must be percent escaped; this is
encoded as %25, %0D and %0A. Only uppercase letters should be used in
the hexadecimal representation. Other characters may be percent escaped
for easier debugging. All these Data lines are considered one data
stream up to the OK or ERR response. Status and Inquiry Responses
may be mixed with the Data lines.
@item INQUIRE @var{keyword}> <parameters>
Server needs further information from the client. The client should
answer with a command which is allowed after an inquiry. Note that the
server does not confirm that client command but either continues
processing or ends processing with an error status. Not all commands
are allowed.
@end table
A client should only check the first letter of each line and then skip
over to the next token (except for data lines where the raw data starts
exactly after 2 bytes). Lines larger than 1000 bytes should be
treated as a communication error. (The rationale for having a line
length limit is to allow for easier multiplexing of multiple channels).
@appendixsubsec Client requests
The server waits for client requests after he sent an Okay or Error.
The client should not issue a request in other cases with the
exception of the CANCEL command.
@example
@var{command} <parameters>
@end example
@var{command} is a one word string without preceding white space.
Parameters are command specific, CR, LF and the percent signs should be
percent escaped as described above. To send a backslash as the last
character it should also be percent escaped. Percent escaping is
allowed anywhere in the parameters but not in the command. The line
ends with a CR, LF or just a LF.
Not yet implemented feature: If there is a need for a parameter list
longer than the line length limit (1000 characters including command and
CR, LF), the last character of the line (right before the CR/LF or LF)
must be a non-escape encoded backslash. The following line is then
expected to be a continuation of the line with the backslash replaced by
a blank and the line ending removed.
@example
D <raw data>
@end example
Raw data to the server. There must be exactly one space after the 'D'.
The values for '%', CR and LF must be percent escaped; this is encoded
as %25, %0D and %0A. Only uppercase letters should be used in the
hexadecimal representation. Other characters may be percent escaped for
easier debugging. All these Data lines are considered one data stream
up to the OKAY or ERROR response. Status and Inquiry Responses may be
mixed with the Data lines.
@example
END
@end example
Lines beginning with a @code{#} or empty lines are ignored. This is
useful to comment test scripts.
Although the commands are application specific, some of them are used by
all protocols and partly directly supported by the Assuan library:
@table @code
@item CANCEL
his is the one special command which aborts the current request. it can
be sent at any time and the server will stop its operation right before
it would send the next response line (of any type).
@item BYE
Close the connect, the server will reply with an @code{OK}.
@item AUTH
Not yet specified as we don't implement it in the first phase. See my
mail to gpa-dev on 2001-10-25 about the rationale for measurements
against local attacks.
@item RESET
Reset the connection but not any existing authentication. The server
should release all resources associated with the connection.
@item END
Used by a client to mark the end of raw data. The server may send END
to indicate a partial end of data.
@end table
@appendixsubsec Error Codes
Here we keep a list of error codes used in any Assuan based
protocol. The format is the string @code{ERR}, white space, the error
number, white space, a textual description of the error.
@table @code
@item 100 Unknown Command
@item 101 Not Implemented
@item 301 certificate has been revoked [DirMngr]
@item 302 no CRL known for this certificate [DirMngr]
@item 303 CRL is too old and a new one could not be retrieved [DirMngr]
