runcon: invalid context
by Tracy Reed 05 May '15

05 May '15

I want to manually run an app within a certain context. When I try running it like so I get the following error: # id -Z unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 # runcon p16001_u:myapp_r:myapp_t:s0:c1 /myapp/startup.sh runcon: invalid context: p16001_u:myapp_r:myapp_t:s0:c1: Invalid argument unconfined should be allowed to transition to any context, right? No AVC is generated so I don't think that's the issue. The user p16001_u exists with category c1, with role myapp_r and myapp_t exists in the policy. I'm unclear as to why this is an invalid context. # semanage user -l Labeling MLS/ MLS/ SELinux User Prefix MCS Level MCS Range SELinux Roles git_shell_u user s0 s0 git_shell_r myapp_u user s0 s0-s0:c0.c1023 myapp_r guest_u user s0 s0 guest_r p16000_u user s0 s0-s0:c0 myapp_r p16001_u user s0 s0-s0:c1 myapp_r p16002_u user s0 s0-s0:c2 myapp_r p16003_u user s0 s0-s0:c3 myapp_r p16004_u user s0 s0-s0:c4 myapp_r p16005_u user s0 s0-s0:c5 myapp_r p16006_u user s0 s0-s0:c6 myapp_r p16007_u user s0 s0-s0:c7 myapp_r p16008_u user s0 s0-s0:c8 myapp_r p16009_u user s0 s0-s0:c9 myapp_r p16010_u user s0 s0-s0:c10 myapp_r root user s0 s0-s0:c0.c1023 staff_r sysadm_r system_r unconfined_r staff_u user s0 s0-s0:c0.c1023 staff_r sysadm_r system_r unconfined_r sysadm_u user s0 s0-s0:c0.c1023 sysadm_r system_u user s0 s0-s0:c0.c1023 system_r unconfined_r unconfined_u user s0 s0-s0:c0.c1023 system_r unconfined_r user_u user s0 s0 user_r xguest_u user s0 s0 xguest_r Any tips greatly appreciated! -- Tracy Reed

Requesting feedback on providing containment of sslh
by James Hogarth 30 Apr '15

30 Apr '15

Hi, I'm the maintainer of sslh and looking to get some feedback on a policy I'm writing for it. It has recently been added to the fedora repositories running unconfined and I'm looking to improve this with running it within its own confined domain. The 'default' state is to listen on tcp/443 and to be able to connect to tcp/80, tcp/443, tcp/5222, tcp/1194 (on both localhost and arbitrary systems) which the default policy is configured for with the option via booleans to let it listen on or connect to any port. I've tried to style this after the services in fedora-selinux on github in an attempt to make it consistent with existing policies. I'd be grateful for any feedback on these before requesting this to be added to the fedora targeted policy. Kind regards, James sslh te file: policy_module(sslh,1.0.0) ######################################## # # Declarations # ## <desc> ## <p> ## Determine whether sslh can connect ## to any tcp port or if it is restricted ## to the standard http, openvpn and jabber ports. ## </p> ## </desc> gen_tunable(sslh_can_connect_any_port, false) ## <desc> ## <p> ## Determine whether sslh can listen ## on any tcp port or if it is restricted ## to the standard http. ## </p> ## </desc> gen_tunable(sslh_can_bind_any_port, false) type sslh_t; type sslh_exec_t; init_daemon_domain(sslh_t, sslh_exec_t) type sslh_config_t; files_config_file(sslh_config_t) type sslh_initrc_exec_t; init_script_file(sslh_initrc_exec_t) type sslh_var_run_t; files_pid_file(sslh_var_run_t) type sslh_unit_file_t; systemd_unit_file(sslh_unit_file_t) ######################################## # # sslh local policy # allow sslh_t sslh_config_t:file read_file_perms; auth_read_passwd(sslh_t) allow sslh_t self:capability { setuid setgid }; allow sslh_t self:process { setcap getcap }; allow sslh_t self:tcp_socket create_stream_socket_perms; sysnet_dns_name_resolve(sslh_t) corenet_all_recvfrom_unlabeled(sslh_t) corenet_all_recvfrom_netlabel(sslh_t) corenet_tcp_sendrecv_generic_if(sslh_t) corenet_udp_sendrecv_generic_if(sslh_t) corenet_tcp_sendrecv_generic_node(sslh_t) corenet_udp_sendrecv_generic_node(sslh_t) corenet_tcp_bind_generic_node(sslh_t) corenet_udp_bind_generic_node(sslh_t) corenet_tcp_bind_http_port(sslh_t) corenet_tcp_sendrecv_http_port(sslh_t) corenet_tcp_connect_http_port(sslh_t) corenet_tcp_connect_ssh_port(sslh_t) corenet_tcp_sendrecv_ssh_port(sslh_t) corenet_tcp_connect_openvpn_port(sslh_t) corenet_tcp_sendrecv_openvpn_port(sslh_t) corenet_tcp_connect_jabber_client_port(sslh_t) corenet_tcp_sendrecv_jabber_client_port(sslh_t) tunable_policy(`sslh_can_connect_any_port',` # allow sslh to connect to any port corenet_tcp_sendrecv_all_ports(sslh_t) corenet_tcp_connect_all_ports(sslh_t) ') tunable_policy(`sslh_can_bind_any_port',` # allow sslh to bind to any port corenet_tcp_sendrecv_all_ports(sslh_t) corenet_tcp_bind_all_ports(sslh_t) ') sslh fc file: /usr/sbin/sslh -- gen_context(system_u:object_r:sslh_exec_t,s0) /usr/sbin/sslh-select -- gen_context(system_u:object_r:sslh_exec_t,s0) /etc/rc\.d/init\.d/sslh -- gen_context(system_u:object_r:sslh_initrc_exec_t,s0) /etc/sslh.cfg -- gen_context(system_u:object_r:sslh_config_t,s0) /usr/lib/systemd/system/sslh.* -- gen_context(system_u:object_r:sslh_unit_file_t,s0) /usr/lib/systemd/system/sslh(a)*.* -- gen_context(system_u:object_r:sslh_unit_file_t,s0) /var/run/sslh(/.*)? gen_context(system_u:object_r:sslh_var_run_t,s0)

"invalid security context" in custom policy

I am trying to confine a custom web application using type enforcement plus MCS to protect multiple instances of the web app from each other.

Proper location for slapd kerberos ticket cache
by Jason L Tibbitts III 24 Apr '15

24 Apr '15

I'm running kerberized openldap, which means I need a kerberos keytab and a ticket cache to provide to slapd. The locations of these files are passed to slapd in environment variables and there's no Fedora default for the file locations. (I guess there aren't too many people running kerberized openldap.) This means I'm free to choose the locations, but selinux gets upset if I choose the "wrong" ones. The keytab is pretty much a fixed configuration file, and is fine to live in /etc/openldap. The ticket cache, however, must be periodically renewed by a cron job, and must be mode 600 owned by the ldap user. The ldap user can't write to /etc/openldap, and I'd prefer not to allow it to do so. /etc/openldap isn't really the right place anyway. The "appropriate" place for this would generally be /var/cache/openldap, but selinux won't let slapd read from there: type=AVC msg=audit(1429645682.010:32711): avc: denied { getattr } for pid=9186 comm="slapd" path="/var/cache/openldap/slapd.krb5cache" dev="dm-1" ino=131308 scontext=system_u:system_r:slapd_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=file permissive=0 Now, I can obviously just run semanage and add an fcontext for that location but if possible I'd like to pick something that doesn't require me to do that for every deployment. Is there a location I can use for this that's allowed by policy currently? Or can I get the default policy modified to provide one? Thanks, - J<

Running iotop as sysadm_r

Hi, I am trying to run iotop as sysadm_t staff_u:sysadm_r:sysadm_t:s0-s0:c0.c1023 This triggers a number of AVC's I figured that perhaps sysadm_t isn't allowed access to the iotop domain.

Strange requirement: confine unconfined
by W. Michael Petullo 14 Apr '15

14 Apr '15

I have a requirement which seems to be most easily satisfied by confining unconfined users. Please let me explain: Imagine some file "foo" that must remain secret. Now imagine a dynamic system which must allow arbitrary (possibly untrustworthy, possibly as-root, possibly user-installed) programs to run. Nothing matters except keeping "foo" secret. Is it possible to construct an SELinux policy which would satisfy such a requirement? For example, it would be helpful to allow users to run their programs unconfined (to allow user-installed, policyless, etc. programs) yet still enforce the policy as it pertains to "foo". Of course, it further seems that SELinux would also have to ensure certain other restrictions apply to unconfined users, such as running semodule or insmod. Alternatively, would it be possible to construct a not-quite-unconfined user by granting all syscalls on all objects *except* those labeled "foo_t" (and semodule, etc.)? I have worked with custom policies before both for software I have written and for standard software, but this seems a bit different. It may be that I have my model wrong, so I would appreciate any guidance whether along the implementation lines I suggested or not (but holding to the original requirements). It is also possible that I have overlooked some existing literature. Thank you! -- Mike :wq

Unexpected behavior in permissive mode

With the policy updates that came with centos 7.1 update, I am trying to update a few local policies we have but with `setenforce 0` I do not get an avc at all when running my app, however enabling it and rerunning it generates one, but without seeing them all that approach would be like wack-a-mole.

Is it possible to cause a process to transition to a new domain but only if it reads a file with a certain label? I am interested in imposing this by modifying the SELinux policy only, that is, not requiring any action on the part of the process itself. You could think of this as a rough analog to HiStar and others' "tainting". -- Mike :wq
