We only want to send pending mon requests when we successfully authenticate. If we are already authenticated, like when we renew our ticket, there is no need to resend pending requests. Signed-off-by: NSage Weil <sage@newdream.net>

The underlying problem is that many mds requests can't be restarted. For example, a restarted create() would return -EEXIST if the original request succeeds. However, we do not want a hung MDS to hang the client too. So, use the _killable wait_for_completion variants to abort on SIGKILL but nothing else. Signed-off-by: NSage Weil <sage@newdream.net>

Add missing _killable_timeout variant for wait_for_completion that will return when a timeout expires or the task is killed.

The auth_reply handler will (re)send any pending requests. For the initial mon authenticate phase, that's correct, but when a auth ticket renewal races with an in-flight request, we may resend a request message that is already in flight. Avoid this by revoking the message before sending it. We should also avoid resending requests at all during ticket renewal; that will come soon. Signed-off-by: NSage Weil <sage@newdream.net>

Use kzalloc rather than the combination of kmalloc and memset.

The remove_session_caps() helper is called when an MDS closes out our session (either normally, or as a result of a failed reconnect), and when we tear down state for umount. If we remove the last cap, and there are no cap migrations in progress, then there is little hope of us flushing out that data to the mds (without heroic efforts to reconnect and flush). So, to avoid leaving inodes pinned (due to dirty state) and crashing after umount, throw out dirty caps state and unpin the inodes. Print a warning to the console so we know something was lost. NOTE: Although we drop wrbuffer refs, we don't actually mark pages clean; maybe a truncate should be queued? Signed-off-by: NSage Weil <sage@newdream.net>

Currently, if our session is closed (due to a timeout, or explicit close, or whatever), we just sit there doing nothing unless/until the MDS restarts, at which point we try to reconnect. Change client to attempt an immediate reconnect if our session is closed. Note that currently the MDS doesn't support this, and our attempt will fail. We'll get a session CLOSE, our caps and dirty cap state will be dropped, and the client will be free to attempt to reconnect. That's clearly not as nice as a successful reconnect, but it at least allows us to try to carry on, and in the future the MDS will support a reconnect and we will fare better.

Pass a ceph_mds_session, since the caller has it. Remove the dead code for sending empty reconnects. It used to be used when the MDS contacted _us_ to solicit a reconnect, and we could reply saying "go away, I have no session." Now we only send reconnects based on the mds map, and only when we do in fact have an open session. Signed-off-by: NSage Weil <sage@newdream.net>

We used to infer reconnect success by watching the MDS state, essentially assuming that hearing nothing meant things were ok. That wasn't particularly reliable. Instead, the MDS replies with an explicit OPEN message to indicate success. Strictly speaking, this is a protocol change, but it is a backwards compatible one that does not break new clients + old servers or old clients + new servers. At least not yet. Drop unused @all argument from kick_requests while we're at it. Signed-off-by: NSage Weil <sage@newdream.net>

On OPENING we shouldn't have any caps (or releases). On CLOSING, we should wait until we succeed (and throw it all out), or don't (and are OPEN again). On RECONNECTING we can wait until we are OPEN. Signed-off-by: NSage Weil <sage@newdream.net>

If the MDS restarts, the expire caps state is no longer shared, and can be thrown out. Caps state will be rebuilt on the MDS during the reconnect process that follows. Zero out any release messages and adjust the release counter accordingly. Signed-off-by: NSage Weil <sage@newdream.net>

The CEPH_FEATURE_NOSRCADDR protocol feature avoids putting the full source address in each message header (twice). This patch switches the client to the new scheme, and _requires_ this feature on the server. The server will support both the old and new schemes. That means an old client will work with a new server, but a new client will not work with an old server. Signed-off-by: NSage Weil <sage@newdream.net>
