Subject: [bug report] RDMA/rxe: Replace pr_xxx by rxe_dbg_xxx in rxe_mr.c
Date: Fri, 18 Nov 2022 18:00:53 +0300 [thread overview]
Message-ID: <Y3eeJW0AdyJYhYyQ@kili> (raw)
Hello Bob Pearson,
This is a semi-automatic email about new static checker warnings.
The patch 2778b72b1df0: "RDMA/rxe: Replace pr_xxx by rxe_dbg_xxx in
rxe_mr.c" from Nov 3, 2022, leads to the following Smatch complaint:
drivers/infiniband/sw/rxe/rxe_mr.c:527 rxe_invalidate_mr()
error: we previously assumed 'mr' could be null (see line 526)
drivers/infiniband/sw/rxe/rxe_mr.c
525 mr = rxe_pool_get_index(&rxe->mr_pool, key >> 8);
526 if (!mr) {
^^^
"mr" is NULL.
527 rxe_dbg_mr(mr, "No MR for key %#x\n", key);
^^
Dereference.
528 ret = -EINVAL;
529 goto err;
regards,
dan carpenter
