[ewg] [PATCH] RDMA/nes: Fixes for OFED-3.5 RC3

2012-12-13 Thread Tatyana Nikolova

RDMA/nes: Fixes for OFED-3.5 RC3

1. Backports for ethtool ops (which allow turning on/off tx, rx, sg, tso)
   are added for RHEL 6.2 and 6.3
2. Fix for crash caused by improper skb ip_summed field setting
   when tx checksum is disabled
3. Fix for crash when registering MR with zero length

[ewg] [PATCH] RDMA/nes: Fix for TSO low nic throughput - linux-next-pending

2012-09-07 Thread Tatyana Nikolova

Fix for TSO low nic throughput with linux-3.5
skb_is_gso() is changed to bool and returns 1 instead of MSS.
The gso_size from skb_shared_info is now used to pass MSS to hardware.

(the patch is linux-next-pending)

[ewg] [PATCH] RDMA/ucma.c: Different fix for ucma context uid=0, causing iWarp RDMA applications to fail in connection establishment

2012-08-07 Thread Tatyana Nikolova

Fix for ucma context uid=0, causing iWarp RDMA applications to fail in 
connection establishment.

This is a new patch addressing the librdmacm segfault when 
RDMA_CM_EVENT_ESTABLISHED event shows up with evt->id_priv = NULL
In the ucma_event_handler(), ctx->file->mut is moved up to prevent race 
conditions and protect from assigning zero ucma ctx->uid to asynchronously 
generated events.

2012-08-02 Thread Tatyana Nikolova

Fix for ucma context uid=0, causing iWarp RDMA applications to fail in 
connection establishment.

If the context uid is not set before calling rdma_accept(), the 
RDMA_CM_EVENT_ESTABLISHED event generated asynchronously by successfull 
rdma_accept ends up with zero ucma context uid, resulting in segfault at 
librdmacm.so
