increased ib-verbs buffer size

2009-08-05T00:07:04+00:00

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. (4 x page-size)

ib-verbs: don't append ioq_entry to pending_list if first attempt of writing to network fails

2009-07-16T06:15:04+00:00

* 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.

ib-verbs error log enhancement

2009-06-03T13:00:08+00:00

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.
