This patch allows ports to have different link layers: IB_LINK_LAYER_INFINIBAND or IB_LINK_LAYER_ETHERNET. This is required for adding IBoE (InfiniBand-over-Ethernet, aka RoCE) support. For devices that do not provide an implementation for querying the link layer property of a port, we return a default value based on the transport: RMA_TRANSPORT_IB nodes will return IB_LINK_LAYER_INFINIBAND and RDMA_TRANSPORT_IWARP nodes will return IB_LINK_LAYER_ETHERNET.

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a pktcdvd_device from the global pkt_devs array. The index into this array is provided directly by the user and is a signed integer, so the comparison to ensure that it falls within the bounds of this array will fail when provided with a negative index. This can be used to read arbitrary kernel memory or cause a crash due to an invalid pointer dereference. This can be exploited by users with permission to open /dev/pktcdvd/control (on many distributions, this is readable by group "cdrom"). Signed-off-by:

The HW by default has RX coalescing on. For iWARP connections, this causes a 100ms delay in connection establishement due to the ingress MPA Start message being stalled in HW. So explicitly turn RX coalescing off when setting up iWARP connections. This was causing very bad performance for NP64 gather operations using Open MPI, due to the way it sets up connections on larger jobs. Signed-off-by:

The PL310 on the ct-ca9x4 tile for the Versatile Express does not need to add additional latency when accessing its cache RAMs. Unfortunately, the boot monitor sets this up for an 8-cycle delay on reads and writes, resulting in greatly reduced memory performance when the L2 cache is enabled. This patch sets the L2 RAM latencies to the correct value of 1 cycle on the ct-ca9x4 tile before enabling the L2 cache. Acked-by:

f4347553 removed the edac polling mechanism in favor of using a notifier chain for conveying MCE information to edac. However, the module removal path didn't test whether the driver had setup the polling function workqueue at all and the rmmod process was hanging in the kernel at try_to_del_timer_sync() in the cancel_delayed_work() path, trying to cancel an uninitialized work struct. Fix that by adding a balancing check to the workqueue removal path. Signed-off-by:

We want interrupts disabled on all paths leading to RESTORE_ALL; otherwise, we are risking an IRQ coming between the updates of alpha_mv->hae_cache and *alpha_mv->hae_register and set_hae() within the IRQ getting badly confused. RESTORE_ALL used to play with disabling IRQ itself, but that got removed back in 2002, without making sure we had them disabled on all paths. It's cheaper to make sure we have them disabled than to revert to original variant... Remove the detritus left from that commit back in 2002; we used to need a reload of $0 and $1 since swpipl would change those, but doing that had become pointless when we stopped doing swpipl in there...

Thomas Pollet noticed that the remap_file_pages() system call in fremap.c has a potential overflow in the first part of the if statement below, which could cause it to process bogus input parameters. Specifically the pgoff + size parameters could be wrap thereby preventing the system call from failing when it should. Reported-by:

Currently we map 1 MB section while setting up SRAM on OMAPs Regardless of the actual memory. The physical OCM RAM available on OMAP SOCs is in order of KBs. This patch maps only available sram and cleans up some un-necessary cpu_is_xxx checks. Mapping un-available or non-accessible(secure) memory on the newer ARM processor is dangerous. Because ARM CPUs can now speculatively prefetch, we should avoid mapping any no-existing or secure memory. Signed-off-by:
