commit 963916fdb3e5ad4af57ac959b5a03bf23f7568ca upstream. Once in_dev_get is called to receive in_device pointer, the in_device reference counter is increased, but if there are no ipv4 addresses configured on the net-device the ifa_list will be null, resulting in a flow that doesn't call in_dev_put to decrease the ref_cnt. This was exposed when running RoCE over ipv6 without any ipv4 addresses configured Fixes: commit 8e3867310c90 ("IB/cma: Fix a race condition in iboe_addr_get_sgid()") Signed-off-by: Michal Kalderon <Michal.Kalderon@cavium.com> Signed-off-by: Ariel Elior <Ariel.Elior@cavium.com> Signed-off-by: Doug Ledford <dledford@redhat.com> Cc: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
