[PATCH V3 0/5] Add LE hash collision bug fix for active and passive offloaded connections

This patch series fixes the LE hash collision issue in cxgb4 and RDMA/cxgb4 drivers in kernel.org. If the hash functionality is enabled in T4 then tuple information of active and passive offloaded connections are stored in DDR3 memory. LE (Lookup Engine) implements the interface to search this

[PATCH V3 1/5] cxgb4: Add T4 filter support

The T4 architecture is capable of filtering ingress packets at line rate using the rule in TCAM. If packet hits a rule in the TCAM then it can be either dropped or passed to the receive queues based on a rule settings. This patch adds framework for managing filters and to use T4's filter

[PATCH V3 2/5] cxgb4: Add LE hash collision bug fix path in LLD driver

It supports establishing passive open connection through firmware filter work request. Passive open connection will go through this path as now instead of listening server we create a server filter which will redirect the incoming SYN packet to the offload queue. It divides filter region into

[PATCH V3 5/5] RDMA/cxgb4: Fix bug for active and passive LE hash collision path

Retries active opens for INUSE errors. Logs any active ofld_connect_wr error replies. Sends ofld_connect_wr on same ctrlq. It needs to go on the same control txq as regular CPL active/passive messages. Retries on active open replies with EADDRINUSE. Uses active open fw wr only if active

[PATCH V3 3/5] RDMA/cxgb4: Fix LE hash collision bug for active open connection

It enables establishing active open connection using fw_ofld_connection work request when cpl_act_open_rpl says TCAM full error which may be because of LE hash collision. Current support is only for IPv4 active open connections. Sets ntuple bits in active open requests. For T4 firmware greater

[PATCH V3 4/5] RDMA/cxgb4: Fix LE hash collision bug for passive open connection

It establishes passive open connection through firmware work request. Passive open connection will go through this path as now instead of listening server we create a server filter which will redirect the incoming SYN packet to the offload queue. After this driver tries to establish the connection

Re: Dapltest test error DAT_CONN_QUAL_IN_USE

Hi Arlin, There was already a bug logged in openfabrics bugzilla regarding this. Following is a link for the same. http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2400 I have assigned this bug to your name. Thanks, Vipul On 01-12-2012 01:46, Davis, Arlin R wrote:

[PATCH] infiniband-diags: Remove Red Hat-ism.

Future release of Fedora are going to remove /etc/sysconfig/network which we source to get $HOSTNAME. Bash (and sh) set $HOSTNAME in the shell by default, so we should be safe to use that here. This adds the benefit of working across multiple distributions if that is required in the future.
