Subject: [bug report] kmemleak observed on bnxt_re
Date: Tue, 26 Mar 2024 14:50:48 +0800	[thread overview]
Message-ID: <CAHj4cs-8vJNVA48BHKQ=cvNB7=aO2_XE2zp_0Fus44ea8wL2Ew@mail.gmail.com> (raw)

Hello

I found this kmemleak issue after system boots up with the latest
linux tree, please help check it and let me know if you need any info,
thanks.

(gdb) l *(bnxt_re_alloc_pd+0x3d0)
0x22160 is in bnxt_re_alloc_pd (drivers/infiniband/hw/bnxt_re/ib_verbs.c:678).
673 goto dbfail;
674 }
675 }
676
677 if (!udata)
678 if (bnxt_re_create_fence_mr(pd))
679 ibdev_warn(&rdev->ibdev,
680    "Failed to create Fence-MR\n");
681 active_pds = atomic_inc_return(&rdev->stats.res.pd_count);
682 if (active_pds > rdev->stats.res.pd_watermark)
