Vlad, can you please pull this change into OFED?
next_port should be between sysctl_local_port_range[0] and [1]. However, it is initially set to a random value. If the value is negative, next_port can fall outside of this range because of the % operator returning a negative value.Signed-off-by: Sean Hefty <[EMAIL PROTECTED]> --- drivers/infiniband/core/cma.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/infiniband/core/cma.c b/drivers/infiniband/core/cma.c index eb15119..b0831cb 100644 --- a/drivers/infiniband/core/cma.c +++ b/drivers/infiniband/core/cma.c @@ -2772,8 +2772,8 @@ static int cma_init(void) int ret;get_random_bytes(&next_port, sizeof next_port);- next_port = (next_port % (sysctl_local_port_range[1] - - sysctl_local_port_range[0])) + + next_port = ((unsigned int) next_port % + (sysctl_local_port_range[1] - sysctl_local_port_range[0])) + sysctl_local_port_range[0]; cma_wq = create_singlethread_workqueue("rdma_cm"); if (!cma_wq)
