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>

Support running adbd in the su domain. When adbd runs as root, it transitions into the su domain. Add the various rules to support this. This is needed to run the adbd and shell domains in enforcing on userdebug / eng devices without breaking developer workflows. Change-Id: Ib33c0dd2dd6172035230514ac84fcaed2ecf44d6

debuggerd: Allow "debug.db.uid" usage Allow the use of debug.db.uid on userdebug / eng builds. Setting this property allows debuggerd to suspend a process if it detects a crash. Make debug.db.uid only accessible to the su domain. This should not be used on a user build. Only support reading user input on userdebug / eng builds.
