2016-05-26IB/core: Make device counter infrastructure dynamicChristoph Lameter
In practice, each RDMA device has a unique set of counters that the hardware implements. Having a central set of counters that they must all adhere to is limiting and causes many useful counters to not be available. Therefore we create a dynamic counter registration infrastructure. The driver must implement a stats structure allocation routine, in which the driver must place the directory name it wants, a list of names for all of the counters, an array of u64 counters themselves, plus a few generic configuration options. We then implement a core routine to create a sysfs file for each of the named stats elements, and a core routine to retrieve the stats when any of the sysfs attribute files are read. To avoid excessive beating on the stats generation routine in the drivers, the core code also caches the stats for a short period of time so that someone attempting to read all of the stats in a given device's directory will not result in a stats generation call per file read. Future work will attempt to standardize just the shared stats elements, and possibly add a method to get the stats via netlink in addition to sysfs.

2016-05-13i40iw: Remove unnecessary synchronize_irq() before free_irq()Lars-Peter Clausen
Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed. Patch was generated using the following semantic patch: // <smpl> @@ expression irq; @@ -synchronize_irq(irq); free_irq(irq, ...); // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reviewed-by: Leon Romanovsky <leonro@mellanox.com> Acked-by: Faisal Latif <faisal.latif#intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-05-13IB/core: Enhance ib_map_mr_sg()Bart Van Assche
The SRP initiator allows to set max_sectors to a value that exceeds the largest amount of data that can be mapped at once with an mlx4 HCA using fast registration and a page size of 4 KB. Hence modify ib_map_mr_sg() such that it can map partial sg-elements. If an sg-element has been mapped partially, let the caller know which fraction has been mapped by adjusting *sg_offset.

2016-04-06i40iw: avoid potential uninitialized variable useArnd Bergmann
gcc finds that the i40iw_make_cm_node() function in the recently added i40iw driver uses an uninitilized variable as an index into an array if CONFIG_IPV6 is disabled and the driver uses IPv6 mode: drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node': drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized] ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr); As far as I can tell, this code path can not be used because the ipv4 variable is always set with CONFIG_IPV6 is disabled, but it's better to be sure and prevent the undefined behavior, as well as shut up that warning in a proper way. This adds an 'else' clause for the case we get the warning about, causing the function to return an error in a controlled way. To avoid adding extra mess with combined io()/#ifdef clauses, I'm also converting the existing #ifdef into a more readable if(IS_ENABLED()) check.
