* [PATCH AUTOSEL 5.15 4/9] sctp: handle invalid error codes without calling BUG() [not found] <20230829133316.520410-1-sashal@kernel.org> @ 2023-08-29 13:33 ` Sasha Levin 0 siblings, 0 replies; 2+ messages in thread From: Sasha Levin @ 2023-08-29 13:33 UTC (permalink / raw) To: linux-kernel, stable Cc: Dan Carpenter, David S . Miller, Sasha Levin, vyasevich, nhorman, marcelo.leitner, edumazet, kuba, pabeni, linux-sctp, netdev From: Dan Carpenter <dan.carpenter@linaro.org> [ Upstream commit a0067dfcd9418fd3b0632bc59210d120d038a9c6 ] The sctp_sf_eat_auth() function is supposed to return enum sctp_disposition values but if the call to sctp_ulpevent_make_authkey() fails, it returns -ENOMEM. This results in calling BUG() inside the sctp_side_effects() function. Calling BUG() is an over reaction and not helpful. Call WARN_ON_ONCE() instead. This code predates git.
