Switch from radix tree to rbtree for snap realms. This is much more appropriate given that realm keys are few and far between. Signed-off-by: NSage Weil <sage@newdream.net>

The rbtree is a more appropriate data structure than a radix_tree. It avoids extra memory usage and simplifies the code. It also fixes a bug where the debugfs 'mdsc' file wasn't including the most recent mds request. Signed-off-by: NSage Weil <sage@newdream.net>

This ensures that if/when we reopen the connection, we can requeue work on the connection immediately, without waiting for an old timer to expire. Queue new delayed work inside con->mutex to avoid any race. This fixes problems with clients failing to reconnect to the MDS due to the client_reconnect message arriving too late (due to waiting for an old delayed work timeout to expire).

Fix the messenger to allow a ceph_con_open() during the fault callback. Previously the work wasn't getting queued on the connection because the fault path avoids requeued work (normally spurious). Loop on reopening by checking for the OPENING state bit. This fixes OSD reconnects when a TCP connection drops. Signed-off-by: NSage Weil <sage@newdream.net>

The test was backwards from commit b3d1dbbd: keep the message if the connection _isn't_ lossy. This allows the client to continue when the TCP connection drops for some reason (network glitch) but both ends survive. Signed-off-by: NSage Weil <sage@newdream.net>

We were invalidating mapping pages when dropping FILE_CACHE in __send_cap(). But ceph_check_caps attempts to invalidate already, and also checks for success, so we should never get to this point. Signed-off-by: NSage Weil <sage@newdream.net>

If a sync read gets a short result from the OSD, it may need to do a getattr to see if it is short due to reaching end-of-file. The getattr was being done while holding a reference to FILE_RD, which can lead to a deadlock if the MDS is revoking that capability bit and can't process the getattr until it does. We fix this by setting a flag if EOF size validation is needed, and doing the getattr in ceph_aio_read, after the RD cap ref is dropped. If the read needs to be continued, we loop and continue traversing the file. Signed-off-by: NSage Weil <sage@newdream.net>

Try to invalidate pages in ceph_check_caps() if FILE_CACHE is being revoked. If we fail, queue an immediate async invalidate if FILE_CACHE is being revoked. (If it's not being revoked, we just queue the caps for later evaluation later, as per the old behavior.) Signed-off-by: NSage Weil <sage@newdream.net>

In the cases where we either do a sync read or a write, we need to make sure that everything in the page cache is flushed. In the case of a sync write we invalidate the relevant pages, so that subsequent read/write reflects the new data written.

The auth_x protocol implements support for a kerberos-like mutual authentication infrastructure used by Ceph. We do not simply use vanilla kerberos because of scalability and performance issues when dealing with a large cluster of nodes providing a single logical service. Auth_x provides mutual authentication of client and server and protects against replay and man in the middle attacks. It does not encrypt the full session over the wire, however, so data payload may still be snooped. Signed-off-by: NYehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: NSage Weil <sage@newdream.net>

Previously, if the MDS request was interrupted, we would unregister the request and ignore any reply. This could cause the caps or other cache state to become out of sync. (For instance, aborting dbench and doing rm -r on clients would complain about a non-empty directory because the client didn't realize it's aborted file create request completed.) Even we don't unregister, we still can't process the reply normally because we are no longer holding the caller's locks (like the dir i_mutex). So, mark aborted operations with r_aborted, and in the reply handler, be sure to process all the caps. Do not process the namespace changes, though, since we no longer will hold the dir i_mutex. The dentry lease state can also be ignored as it's more forgiving. Signed-off-by: NSage Weil <sage@newdream.net>
