In the process of moving the debug counters sysfs entries, the commit mentioned below eliminated the cm_infiniband sysfs directory. This sysfs directory was tied to the cm_port object allocated in procedure cm_add_one(). Before the commit below, this cm_port object was freed via a call to kobject_put(port->kobj) in procedure cm_remove_port_fs(). Since port no longer uses its kobj, kobject_put(port->kobj) was eliminated. This, however, meant that kfree was never called for the cm_port buffers. Fix this by adding explicit kfree(port) calls to functions cm_add_one() and cm_remove_one(). Note: the kfree call in the first chunk below (in the cm_add_one error flow) fixes an old, undetected memory leak. Fixes: c87e65cf ("RDMA/cm: Move debug counters to be under relevant IB device") Link: https://lore.kernel.org/r/20190916071154.20383-2-leon@kernel.orgSigned-off-by:
