Merge tag 'per-namespace-ipc-sysctls-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull ipc sysctl namespace updates from Eric Biederman: "This updates the ipc sysctls so that they are fundamentally per ipc namespace. Previously these sysctls depended upon a hack to simulate being per ipc namespace by looking up the ipc namespace in read or write. With this set of changes the ipc sysctls are registered per ipc namespace and open looks up the ipc namespace. Not only does this series of changes ensure the traditional binding at open time happens, but it sets a foundation for being able to relax the permission checks to allow a user namspace root to change the ipc sysctls for an ipc namespace that the user namespace root requires. To do this requires the ipc namespace to be known at open time" * tag 'per-namespace-ipc-sysctls-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ipc: Remove extra braces ipc: Check permissions for checkpoint_restart sysctls at open time ipc: Remove extra1 field abuse to pass ipc namespace ipc: Use the same namespace to modify and validate ipc: Store ipc sysctls in the ipc namespace ipc: Store mqueue sysctls in the ipc namespace
