Hello, I am new with selinux and I have a problem: My system: Fedora Core 5, FC5 - 2.6.16-1.2122 SMP I am trying to set communication policies between two machines and I am using the set of commands implemented by ipsec-tools. I am running the command: setkey -v -f set.conf Contents of the file set.conf (it had more things at the beginning but I reduced it while looking for the cause of the error): flush; spdflush; spdadd src dest any -ctx 1 1 "user_u:object_r:user_t" -P out ipsec esp/transport//require ; I always receive the same output at the end: "Invalid Argument". sadb_msg{ version=2 type=9 errno=0 satype=0 len=2 reserved=0 seq=0 pid=16090 sadb_msg{ version=2 type=9 errno=0 satype=0 len=2 reserved=0 seq=0 pid=16090 sadb_msg{ version=2 type=19 errno=0 satype=0 len=2 reserved=0 seq=0 pid=16090 sadb_msg{ version=2 type=19 errno=0 satype=0 len=2 reserved=0 seq=0 pid=16090 sadb_msg{ version=2 type=14 errno=0 satype=0 len=16 reserved=0 seq=0 pid=16090 sadb_ext{ len=4 type=18 } sadb_x_policy{ type=2 dir=2 id=0 priority=2147483648 } { len=16 proto=50 mode=1 level=2 reqid=0 } sadb_ext{ len=3 type=5 } sadb_address{ proto=255 prefixlen=32 reserved=0x0000 } sockaddr{ len=16 family=2 port=0 82cb2034 } sadb_ext{ len=3 type=6 } sadb_address{ proto=255 prefixlen=32 reserved=0x0000 } sockaddr{ len=16 family=2 port=0 82cb2035 } sadb_ext{ len=4 type=24 } sadb_x_sec_ctx{ doi=1 alg=1 length=23, context:user_u:object_r:user_t} sadb_msg{ version=2 type=14 errno=22 satype=0 len=2 reserved=0 seq=0 pid=16090 The result of line 4: Invalid argument. I followed the procedure and it looks like the problem is not related to ipsec-tools but to something in the kernel, because it returns errno=22. Running the same command without the ctx extension works fine. Does anyone have any idea?
