IPoIB: Clear high octet in QP number

2006-11-16T21:56:45Z

IPoIB assumes that high (reserved) octet in the hardware address is 0, and copies it into the QPN. This violates RFC 4391 (which requires that the high 8 bits are ignored on receive), and will result in an invalid QPN being used when interoperating with IPoIB connected mode.

[PATCH] IB/ipath - fix driver build for platforms with PCI, but not HT

2006-11-16T19:43:37Z

The PCI Express and Hypertransport chip-specific source files should only be built when the kernel has the capability of actually compiling them. This fixes the driver build on, for example, ia64.

IB/mad: Fix race between cancel and receive completion

2006-11-13T17:38:07Z

When ib_cancel_mad() is called, it puts the canceled send on a list and schedules a "flushed" callback from process context. However, this leaves a window where a receive completion could be processed before the send is fully flushed. This is fine, except that ib_find_send_mad() will find the MAD and return it to the receive processing, which results in the sender getting both a successful receive and a "flushed" send completion for the same request. Understandably, this confuses the sender, which is expecting only one of these two callbacks, and leads to grief such as a use-after-free in IPoIB. Fix this by changing ib_find_send_mad() to return a send struct only if the status is still successful (and not "flushed"). The search of the send_list already had this check, so this patch just adds the same check to the search of the wait_list. Signed-off-by: Roland Dreier

RDMA/amso1100: Fix && typo

2006-11-13T17:38:07Z

Fix the AMSO1100 firmware version computation, which was broken due to "&&" being used where "&" should have. Signed-off-by: Jean Delvare Signed-off-by: Roland Dreier

RDMA/amso1100: Fix unitialized pseudo_netdev accessed in c2_register_device

2006-11-13T17:38:04Z

Rework some load-time error handling: c2_register_device() leaked when it failed, and the function that called it didn't check the return code. Signed-off-by: Tom Tucker Signed-off-by: Roland Dreier

IB/ehca: Activate scaling code by default

2006-11-13T16:46:28Z

Change ehca's Kconfig to activates scaling code as default. After several measurements we saw that this feature prevents dropped packets (UD) in stress situation. Thus, enabling it helps to improve ehca's bandwidth through IPoIB. Signed-off-by: Hoang-Nam Nguyen Signed-off-by: Roland Dreier

IB/ehca: Use named constant for max mtu

2006-11-13T16:46:28Z

Define and use a constant EHCA_MAX_MTU instead hardcoded value. Signed-off-by: Hoang-Nam Nguyen Signed-off-by: Roland Dreier
