Landlock only implements the\ncred_prepare hook, not cred_transfer, so KEYCTL_SESSION_TO_PARENT causes\nall information on Landlock restrictions to be lost.\n\nThis basically means that a process with the ability to use the fork()\nand keyctl() syscalls can get rid of all Landlock restrictions on\nitself.\n\nFix it by adding a cred_transfer hook that does the same thing as the\nexisting cred_prepare hook. (Implemented by having hook_cred_prepare()\ncall hook_cred_transfer() so that the two functions are less likely to\naccidentally diverge in the future.)"
