Create new conditional userdebug_or_eng Create a new m4 macro called userdebug_or_eng. Arguments passed to this macro are only emitted if we're performing a userdebug or eng build. Merge shell.te and shell_user.te and eliminate duplicate lines. Same for su.te and su_user.te Change-Id: I8fbabca65ec392aeafd5b90cef57b5066033fad0

# File types must be defined for file_contexts.
Make sure exec_type is assigned to all entrypoint types. Some file types used as domain entrypoints were missing the exec_type attribute. Add it and add a neverallow rule to keep it that way. Change-Id: I7563f3e03940a27ae40ed4d6bb74181c26148849 Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

userdebug_or_eng(`
Clarify init_shell, shell, and su domain usage. init_shell domain is now only used for shell commands or scripts invoked by init*.rc files, never for an interactive shell. It was being used for console service for a while but console service is now assigned shell domain via seclabel in init.rc. We may want to reconsider the shelldomain rules for init_shell and whether they are still appropriate. shell domain is now used by both adb shell and console service, both of which also run in the shell UID. su domain is now used not only for /system/bin/su but also for adbd and its descendants after an adb root is performed.

domain_auto_trans(dumpstate, su_exec, su)
Restrict the ability to set SELinux enforcing mode to init. Also make su and shell permissive in non-user builds to allow use of setenforce without violating the neverallow rule. Change-Id: Ie76ee04e90d5a76dfaa5f56e9e3eb7e283328a3f Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Dumpstate runs the same from shell as service. Without this change, any selinux warning you might get when running dumpstate from init do not show up when running from the shell as root. This change makes them run the same. Change-Id: I6b74e0f6f48f47952a2dbe7728b1853008f60dbb

Tweak rules for su domain. 1) Remove explicit allow statements. Since su is in permmissive, there's no need to ever specify allow statements for su. 2) Remove unconfined_domain(su). Su is already permissive, so there's no need to join the unconfined domain, and it just makes getting rid of unconfined more difficult. 3) Put su into app_domain(). This addresses, in a roundabout sorta way, the following denial: type=1400 audit(0.0:4): avc: denied { setsched } for scontext=u:r:system_server:s0 tcontext=u:r:su:s0 tclass=process permissive=0 which comes up while testing media processes as root. We already put the shell user into this domain, so adding su to this domain ensures other processes can communicate consistently with su spawned processes.

su.te: suppress service_manager related denials. The su domain is always permissive, and will always be permissive. It never makes sense to show su related denials, as they just cause a false sense of alarm. Suppress service_manager related denials. For example: SELinux : avc: denied { find } for service=SurfaceFlinger scontext=u:r:su:s0 tcontext=u:object_r:surfaceflinger_service:s0 tclass=service_manager SELinux : avc: denied { find } for service=activity scontext=u:r:su:s0 tcontext=u:object_r:system_server_service:s0 tclass=service_manager While I'm here, suppress other recent additionsl to security_classes as well (keystore_key, debuggerd, drmservice) Change-Id: I844ad8da5ada09775646b5f32c9405e7b73797f9
