I'm guessing that this\nwas done to allow creating psocks for non-inet sockets.\n\nUnfortunately the destruction path for psock includes the ULP\nunwind, so we need to fail the sk_psock_init() itself.\nOtherwise if ULP is already present we'll notice that later,\nand call tcp_update_ulp() with the sk_proto of the ULP\nitself, which will most likely result in the ULP looping\nits callbacks.\n\ud83d\udccf Published: 2025-02-26T14:57:24.827Z\n\ud83d\udccf Modified: 2025-02-26T14:57:24.827Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/72fa0f65b56605b8a9ae9fba2082f2123f7fe017\n2. https://git.kernel.org/stable/c/922309e50befb0cfa5cb65e4989b7706d6578846\n3. https://git.kernel.org/stable/c/e34a07c0ae3906f97eb18df50902e2a01c1015b6", "creation_timestamp": "2025-02-26T15:26:12.000000Z"}
