sin-ack	fa692e13f9	Kernel: Use real UID/GID when checking for file access ... This aligns the rest of the system with POSIX, who says that access(2) must check against the real UID and GID, not effective ones.	2022-12-11 19:55:37 -07:00
Andreas Kling	c3351d4b9f	Kernel: Make VirtualFileSystem functions take credentials as input ... Instead of getting credentials from Process::current(), we now require that they be provided as input to the various VFS functions. This ensures that an atomic set of credentials is used throughout an entire VFS operation.	2022-08-21 16:02:24 +02:00
Andreas Kling	122d7d9533	Kernel: Add Credentials to hold a set of user and group IDs ... This patch adds a new object to hold a Process's user credentials: - UID, EUID, SUID - GID, EGID, SGID, extra GIDs Credentials are immutable and child processes initially inherit the Credentials object from their parent. Whenever a process changes one or more of its user/group IDs, a new Credentials object is constructed. Any code that wants to inspect and act on a set of credentials can now do so without worrying about data races.	2022-08-20 18:32:50 +02:00
