num_rcv_contexts sets the number of user contexts, both receive and send. Renaming it to num_user_contexts makes sense to reflect its true meaning. When num_rcv_contexts is 0, the default behavior is the number of CPU cores instead of 0 contexts. This commit changes the variable num_rcv_contexts to num_user_contexts, and it also makes any negative value for this variable default to the number of CPU cores, so if num_user_contexts is set >= 0, the value will number of contexts.

If driver is loaded with parameter hdrq_entsize=0, then there's a NULL dereference when the driver gets unloaded. This causes a kernel Oops and prevents the module from being unloaded. This patch fixes this issue by making sure -EINVAL gets returned when hdrq_entsize=0. Reviewed-by:

A code inspection pointed out that kmalloc_array may return NULL and memset doesn't check the input pointer for NULL, resulting in a possible NULL dereference. This patch fixes this. Reviewed-by:

The kmem_cache_destroy() function tests whether its argument is NULL and then returns immediately. Thus the NULL check before calling this function is not needed. This issue was detected by using the Coccinelle software. Signed-off-by:

Profiling has shown the the atomic is a performance issue for the pio hot path. If multiple cpus allocated an sc's buffer, the cacheline containing the atomic will bounce from L0 to L0. Convert the atomic to a percpu variable. Reviewed-by:

There are holes in the sdma build support routines that do not clean any partially built sdma descriptors after mapping or allocate failures. This patch corrects these issues. Reviewed-by:

The allocation code assumes that the shadow ring cannot be overrun because the credits will limit the allocation. Unfortuately, the progress mechanism in sc_release_update() updates the free count prior to processing the shadow ring, allowing the shadow ring to be overrun by an allocation. Reviewed-by:

It is possible for an SDMA transmission error to happen during the processing of an user SDMA transfer. In that case it is better to detect it early and abort any further attempts to send more packets. Reviewed-by:

Mitko Haralanov authored
The driver pins pages on behalf of user processes in two separate instances - when the process has submitted a SDMA transfer and when the process programs an expected receive buffer. When pinning pages, the driver is required to observe the locked page limit set by the system administrator and refuse to lock more pages than allowed. Such a check was done for expected receives but was missing from the SDMA transfer code path. This commit adds the missing check for SDMA transfers. As of this commit, user SDMA or expected receive requests will be rejected if the number of pages required to be pinned will exceed the set limit. Due to the fact that the driver needs to take the MM semaphore in order to update the locked page count (which can sleep), this cannot be done by the callback function as it [the callback] is executed in interrupt context. Therefore, it is necessary to put all the completed SDMA tx requests onto a separate list (txcmp) and offload the actual clean-up and unpinning work to a workqueue. Reviewed-by:

Convert hfi1_get_user_pages() to use get_user_pages_fast(), which is much fatster. The mm semaphore is still taken to update the pinned page count but is for a much shorter amount of time. Reviewed-by:

There is no need to cleck if the packet queue is allocated when cleaning up a user context. The hfi1_user_sdma_free_queues() function already does all the required checks. Reviewed-by:
