2012-07-31libceph: verify state after retaking con lock after dispatchSage Weil
We drop the con mutex when delivering a message. When we retake the lock, we need to verify we are still in the OPEN state before preparing to read the next tag, or else we risk stepping on a connection that has been closed.

2012-07-31libceph: replace connection state bits with statesSage Weil
Use a simple set of 6 enumerated values for the socket states (CON_STATE_*) and use those instead of the state bits. All of the con->state checks are now under the protection of the con mutex, so this is safe. It also simplifies many of the state checks because we can check for anything other than the expected state instead of various bits for races we can think of. This appears to hold up well to stress testing both with and without socket failure injection on the server side. Signed-off-by: Sage Weil <sage@inktank.com>

The problem is that a sequence like: - start reading message - initialize bio_iter - read half a message - messenger fault, reconnect - restart reading message - ** bio_iter now non-NULL, not reinitialized ** - read past end of bio, crash Instead, initialize the bio_iter unconditionally when we allocate/claim the message for read.

2012-07-31libceph: resubmit linger ops when pg mapping changesSage Weil
The linger op registration (i.e., watch) modifies the object state. As such, the OSD will reply with success if it has already applied without doing the associated side-effects (setting up the watch session state). If we lose the ACK and resubmit, we will see success but the watch will not be correctly registered and we won't get notifies. To fix this, always resubmit the linger op with a new tid. We accomplish this by re-registering as a linger (i.e., 'registered') if we are not yet registered. Then the second loop will treat this just like a normal case of re-registering. This mirrors a similar fix on the userland ceph.git, commit 5dd68b95, and ceph bug #2796.

2012-07-30libceph: fix messenger retrySage Weil
In ancient times, the messenger could both initiate and accept connections. An artifact if that was data structures to store/process an incoming ceph_msg_connect request and send an outgoing ceph_msg_connect_reply. Sadly, the negotiation code was referencing those structures and ignoring important information (like the peer's connect_seq) from the correct ones. Among other things, this fixes tight reconnect loops where the server sends RETRY_SESSION and we (the client) retries with the same connect_seq as last time. This bug pretty easily triggered by injecting socket failures on the MDS and running some fs workload like workunits/direct_io/test_sync_io. Signed-off-by: Sage Weil <sage@inktank.com>

2012-07-27tcp: perform DMA to userspace only if there is a task waiting for itJiri Kosina
Back in 2006, commit 1a2449a87b ("[I/OAT]: TCP recv offload to I/OAT") added support for receive offloading to IOAT dma engine if available. The code in tcp_rcv_established() tries to perform early DMA copy if applicable. It however does so without checking whether the userspace task is actually expecting the data in the buffer. This is not a problem under normal circumstances, but there is a corner case where this doesn't work -- and that's when MSG_TRUNC flag to recvmsg() is used. If the IOAT dma engine is not used, the code properly checks whether there is a valid ucopy.task and the socket is owned by userspace, but misses the check in the dmaengine case. This problem can be observed in real trivially -- for example 'tbench' is a good reproducer, as it makes a heavy use of MSG_TRUNC. On systems utilizing IOAT, you will soon find tbench waiting indefinitely in sk_wait_data(), as they have been already early-copied in tcp_rcv_established() using dma engine. This patch introduces the same check we are performing in the simple iovec copy case to the IOAT case as well. It fixes the indefinite recvmsg(MSG_TRUNC) hangs.
