📋 Description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/mlx4: Prevent shift wrapping in set_user_sq_size()

The ucmd->log_sq_bb_count variable is controlled by the user so this shift can wrap. Fix it by using check_shl_overflow() in the same way that it was done in commit 515f60004ed9 ("RDMA/hns: Prevent undefined behavior in hns_roce_set_user_sq_size()").
