When char is signed and one of the bytes in lmm happens to have a byte value above 127, the result of printing that with %.2X will be 8 hex chars, the first 6 of which are 'F'. Worst case, we'll overrun our 'carefully' allocated buffer. I didn't have the tenacity to work through the gazillion and seven layers of macros behind CERROR, but I assume it'll all end at some function implemented in terms of the kernel's vsnprintf. Use %*phN for a hexdump. That'll cap the number of dumped bytes at 64. If that's a problem, the loop could be replaced by "bin2hex(buffer, lmm, lmm_bytes);". Signed-off-by:

Replaces IS_PO2 by is_power_of_2. It is more accurate to use is_power_of_2 since it returns 1 for numbers that are powers of 2 only whereas IS_PO2 returns 1 for 0 and numbers that are powers of 2. Reviewed-by:

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:

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:

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:
