* transport/ib-verbs: assign to qpreg before accessing it in ↵Raghavendra G2009-11-191-0/+1

* transport/ib-verbs: fix race-condition resulting in freeing of transport ↵Raghavendra G2009-11-161-11/+70
| | | | | | | | | | | | | | | | | while it was still being used. - while handling a failed work completion status, the transport is disconnected. But further down in the code, the transport is still used. There can be a possibility that transport might've been freed by the time control reaches this point.

* transport/ib-verbs: synchronize ib_verbs_recv_completion_proc with ↵Raghavendra G2009-11-162-5/+6
| | | | | | | | | | | | | | | | | | | | ib_verbs_receive so that the former doesn't overwrite the pointer from which latter reads. - There can be a condition wherein, 1. the thread executing ib_verbs_recv_completion_proc (thr 1) stores the buffer pointer and notifies the upper translators about a POLLIN event. 2. the thread waiting for events on socket (thr 2) calls transport_receive, but in ib_verbs_receive it has not still read the data. 3. thr 1 receives work completion event for another work request and overwrites the buffer pointer. 4. thr 2 reads from the new pointer there by missing the data stored in buffer pointed by pointer which got overwritten.

| | | | | | | | | | | | | | | | | not specified. - when listen-host is not specified and there are are no interfaces having adresses belonging to the address-family specified, listen at 0.0.0.0/::0. - this patch is necessary since with AI_ADDRCONFIG, getaddrinfo fails if there are no active interfaces for the address family specified and when listen-host is specified we still want the functionality provided with usage of AI_ADDRCONFIG.

* increased ib-verbs buffer sizeAmar Tumballi2009-08-041-2/+2
| | | | | | | | | | | | | Noticed that in few cases, where ib-verbs doesn't handle a bigger sized buffer to be sent across, which happens without problem in tcp. Caused frame losses in the case where server's reply msg was bigger, hence the msg got dropped at the server end. With this patch ib-verbs buffer size is fixed to 512KB.

* ib-verbs: don't append ioq_entry to pending_list if first attempt of writing ↵Raghavendra G2009-07-151-1/+1
| | | | | | | | | | | | | | | | | | to network fails * fix to bug #101 - When a buffer bigger than ib-verbs-work-request-send-size was attempted to write to network, ib-verbs returns ENOTCONN. Neverthless, the ioq_entry corresponding to the write was appended to the pending lists of ioq_entries waiting to be written to network. This resulted in double free of header, once in protocol_client_xfer and again during cleanup of transport. The transport cleanup happened due to the timeouts of subsequent operations, since ioq_entry corresponding to writev was blocking any other operations from reaching server. Signed-off-by: Anand V.

* ib-verbs error log enhancementAmar Tumballi2009-06-031-3/+10
| | | | | | | | | | | | | Earlier it was thought that only not having 'opensm' running will cause handshake errors in ib-verbs. Recently understood that even having a wrong 'ib-verbs.port' option can also cause the same behavior, and it took more than 5-6 e-mail iterations with the user and lot of brain cycle in support team to understand the problem. Made the log message more descriptive, so user can be find the cause, or can send us email without wasting time. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
