Subject: [PATCH rdma-next 1/1] RDMA/core: Fix socket leak in rdma_dev_init_net
Date: Tue, 12 Aug 2025 15:37:38 +0200 [thread overview]
Message-ID: <20250812133743.1788579-1-haakon.bugge@oracle.com> (raw)
If rdma_dev_init_net() has an early return because the supplied net is
the default init_net, we need to call rdma_nl_net_exit() before
returning.
Fixes: 4e0f7b907072 ("RDMA/core: Implement compat device/sysfs tree in net namespace")
