From d1754c69448f5a723e62beea27f84cfd2167752b Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 3 Feb 2025 11:03:04 +0000 Subject: rxrpc: Fix the rxrpc_connection attend queue handling [ Upstream commit 4241a702e0d0c2ca9364cfac08dbf134264962de ] The rxrpc_connection attend queue is never used because conn::attend_link is never initialised and so is always NULL'd out and thus always appears to be busy. This requires the following fix: (1) Fix this the attend queue problem by initialising conn::attend_link. And, consequently, two further fixes for things masked by the above bug: (2) Fix rxrpc_input_conn_event() to handle being invoked with a NULL sk_buff pointer - something that can now happen with the above change. (3) Fix the RXRPC_SKB_MARK_SERVICE_CONN_SECURED message to carry a pointer to the connection and a ref on it. Signed-off-by: David Howells cc: Marc Dionne cc: Jakub Kicinski cc: "David S.
