* don't load property_contexts from /dataNick Kralevich2014-03-111-1/+0
| | | | | | Bug: 12613118 Change-Id: I5a84b13d2151075d5136e3682431fbcc9307df13 (cherry picked from commit dc3a42bb11dc2aefee37f799b5a1cce87cf35aaf)

* Move restorecon and restorecon_recursive code to libselinux.Stephen Smalley2014-01-281-0/+1
| | | | | | | | | | | | This requires telling libselinux to use the sehandle already obtained by init rather than re-acquiring it internally. init retains ownership of the sehandle because it performs the initial load, uses the sehandle for other purposes (e.g. labeling of directories created via mkdir and labeling of socket files), and handles the policy reload property trigger.

| * | Seed Linux RNG from Hardware RNG at boot during init.Alex Klyubin2013-08-191-0/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux RNG may have little entropy during boot. As more and more devices have a Hardware RNG, we mix in 512 bytes from Hardware RNG (if present) into Linux RNG early during boot (after wait_for_coldboot_done and before property_service_init actions in init). To avoid having to trust the output of Hardware RNG, we do not mix it into the Linux RNG's primary pool or increase the Linux RNG's entropy estimates.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an optional argument to the socket option for specifying a SELinux security context for the socket. Normally the socket security context is automatically computed from the service security context or set using the seclabel option, but this facility allows dealing with two scenarios that cannot be addressed using the existing mechanisms: 1) Use of logwrapper to wrap a service. In this case, init cannot determine the service security context as it does not directly execute it and we do not want logwrapper to run in the same domain as the service. 2) Situations where a service has multiple sockets and we want to label them distinctly.

| | * | init: Retain traditional restart behavior for critical and oneshot services.Mike Kasick2012-03-221-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds an SVC_RESTART state that's used for an explicit "restart" of a running service. This retains the traditional restart behavior for critical and oneshot services (previously altered by 7e36edd8), whereby these services are "simply restarted" instead of counting as a crash (for a critical serivce) or going into the disabled state (for a oneshot service).
| | * | init: Safely restart services to avoid race conditions.Mike Kasick2012-03-221-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, service restarts (either an explicit "restart", or a "stop, start" pair) exhibited a race condition whereby the new (restarting) service process was often spawned before the old (stopping) process had terminated. This may have resulted in the new service process failing to acquire a limited resource (file lock, socket bind, etc.) that the old process had not yet released. Now, a stopping service remains in the SVC_RUNNING state until its exiting process has been reaped by waitpid. This prevents a "stop, start" sequence from spawning a second service process before resources held by the first are released. This enables safe service restarts by stopping the service, waiting for the old service process to terminate, and (only then) starting the new service process. In the event of "restarting" an already stopped service, the previous behavior is maintained whereby the service is simply started. This scenario could be special-cased by the restart command, however, we have observed instances where services are, unintentionally, stopped and started "too quickly," and so simultaneous processes for the same service should never be allowed. Note that this commit alters the behaviors for explicit restarts of critical and oneshot services. Previously these serivces would simply be restarted, whereas now, an explicit restart of a critical service counts as a crash (which may result in a recovery reboot) and oneshot services go into the disabled state.
