When the\n3rd argument buf doesn't match with \"offline\", \"online\" or \"remove\", the\nfunction simply returns -EINVAL and forgets to decrease the reference\ncount of a rpc_xprt object and a rpc_xprt_switch object increased by\nrpc_sysfs_xprt_kobj_get_xprt() and\nrpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of\nboth unused objects.\n\nFix this issue by jumping to the error handling path labelled with\nout_put when buf matches none of \"offline\", \"online\" or \"remove\".\n\ud83d\udccf Published: 2024-07-16T11:29:39.903Z\n\ud83d\udccf Modified: 2025-05-15T12:32:42.433Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/4b22aa42bd4d2d630ef1854c139275c3532937cb\n2. https://git.kernel.org/stable/c/5f6024c05a2c0fdd180b29395aaf686d25af3a0f\n3. https://git.kernel.org/stable/c/776d794f28c95051bc70405a7b1fa40115658a18", "creation_timestamp": "2025-05-15T13:33:35.000000Z"}
