Andreas Kling	ac71775de5	Kernel: Make all syscall functions return KResultOr<T> ... This makes it a lot easier to return errors since we no longer have to worry about negating EFOO errors and can just return them flat.	2021-03-01 13:54:32 +01:00
Andreas Kling	82f86e35d6	Kernel+LibC: Introduce a "dumpable" flag for processes ... This new flag controls two things: - Whether the kernel will generate core dumps for the process - Whether the EUID:EGID should own the process's files in /proc Processes are automatically made non-dumpable when their EUID or EGID is changed, either via syscalls that specifically modify those ID's, or via sys$execve(), when a set-uid or set-gid program is executed. A process can change its own dumpable flag at any time by calling the new sys$prctl(PR_SET_DUMPABLE) syscall. Fixes #4504.	2020-12-25 19:35:55 +01:00
