| Subject: RDMA/qedr: Fix out of bounds index check in query pkey |
| |
| From: Gal Pressman <galpress@amazon.com> |
| |
| [ Upstream commit dbe30dae487e1a232158c24b432d45281c2805b7 ] |
| |
| The pkey table size is QEDR_ROCE_PKEY_TABLE_LEN, index should be tested |
| for >= QEDR_ROCE_PKEY_TABLE_LEN instead of > QEDR_ROCE_PKEY_TABLE_LEN. |
