FLUSH(5) File Formats Manual FLUSH(5)NAME
flush - abort a message
SYNOPSIS
Tflush tag[2] oldtag[2]
Rflush tag[2]
DESCRIPTION
When the response to a request is no longer needed, such as when a user interrupts a process doing a read(2), a Tflush request is sent to
the server to purge the pending response. The message being flushed is identified by oldtag. The semantics of flush depends on messages
arriving in order.
The server must answer the flush message immediately. If it recognizes oldtag as the tag of a pending transaction, it should abort any
pending response and discard that tag. In either case, it should respond with an Rflush echoing the tag (not oldtag) of the Tflush mes-
sage. A Tflush can never be responded to by an Rerror message.
When the client sends the Tflush, it should disregard all messages received with tag oldtag until the corresponding Rflush is received, at
which point oldtag may be recycled for subsequent messages.
Several exceptional conditions are handled correctly by the above specification: sending multiple flushes for a single tag, flushing a
Tflush, and flushing an invalid tag.

ATTACH(5) File Formats Manual ATTACH(5)NAME
attach, session, nop - messages to initiate activity
SYNOPSIS
Tnop tag[2]
Rnop tag[2]
Tsession tag[2] chal[8]
Rsession tag[2] chal[8] authid[28] authdom[48]
Tattach tag[2] fid[2] uid[28] aname[28] ticket[72] auth[13]
Rattach tag[2] fid[2] qid[8] rauth[13]
DESCRIPTION
The nop request does nothing overt but may be used to synchronize the channel between two service hosts initially.
The session request is used to initialize a connection between a client and a server. All outstanding I/O on the connection is aborted.
The set of messages between session requests is called a session. The host's user name (authid) and its authentication domain (authdom)
identify the key to be used when authenticating to this host. The exchanged challenges (chal) are used in the authentication algorithm.
If authid is a null string no authentication is performed in this session.
The tag should be NOTAG (value 0xFFFF) for a nop or session message.
The attach message serves as a fresh introduction from a user on the client machine to a server. The message identifies the user (uid) and
may select the file tree to access (aname). The ticket and auth arguments contains authorization data derived from the exchanged chal-
lenges of the session message; see auth(6).
As a result of the attach transaction, the client will have a connection to the root directory of the desired file tree, represented by
fid. An error is returned if fid is already in use. The server's idea of the root of the file tree is represented by the returned qid.
ENTRY POINTS
An attach transaction will be generated for kernel devices (see intro(3)) when a system call evaluates a file name beginning with Pipe(2)
generates an attach on the kernel device pipe(3). The mount system call (see bind(2)) generates an attach messages to the remote file
server. When the kernel boots, an attach is made to the root device, root(3), and then an attach is made to the requested file server
machine.
