From eac81736e6884484ebb45f8d0cba639f3285382b Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 4 Aug 2009 17:27:52 +0800 Subject: [PATCH] sunrpc: reply AUTH_BADCRED to RPCSEC_GSS with unknown service When an RPC message is received with RPCSEC_GSS with an unknown service (not RPC_GSS_SVC_NONE, RPC_GSS_SVC_INTEGRITY, or RPC_GSS_SVC_PRIVACY), svcauth_gss_accept() returns AUTH_BADCRED, but svcauth_gss_release() subsequently drops the response entirely, discarding the error. Fix that so the AUTH_BADCRED error is returned to the client. Signed-off-by: Wei Yongjun Signed-off-by: J.
