Subject: knfsd: rpcgss: RPC_GSS_PROC_ DESTROY request will get a bad rpc
From: Wei Yongjun <yjwei@xxxxxxxxxxxxxx>
If I send a RPC_GSS_PROC_DESTROY message to NFSv4 server, it will reply with a
bad rpc reply which lacks an authentication verifier. Maybe this patch is
needed.
Send/recv packets as following:
send:
RemoteProcedureCall
xid
rpcvers = 2
prog = 100003
vers = 4
proc = 0
cred = AUTH_GSS
version = 1
gss_proc = 3 (RPCSEC_GSS_DESTROY)
service = 1 (RPC_GSS_SVC_NONE)
verf = AUTH_GSS
checksum
reply:
RemoteProcedureReply
xid
msg_type
reply_stat
accepted_reply
