apio	10c892d606	kernel: Allow null envp in execve() ... As far as I know, this is not standard, but I'm doing this as a convenience for programs using exec() right after clearenv().	2023-08-07 22:48:21 +02:00
apio	bc20e1a31b	kernel: Store FD_CLOEXEC in the file descriptor itself ... Closes #39.	2023-08-03 17:47:18 +02:00
apio	dc35c42371	kernel/VFS: Rework the metadata system so that there is a single metadata struct	2023-08-01 17:20:28 +02:00
apio	4c87d72b44	kernel/binfmt: Add documentation + support script interpreters being scripts themselves	2023-07-31 20:41:18 +02:00
apio	3638d3da46	kernel: Add binary format for shebang scripts	2023-07-30 18:46:19 +02:00
apio	1c76675e40	kernel: Add a framework to add more executable formats, possibly from userspace ... This lets us implement shebangs and possibly an interface similar to Linux's binfmt_misc.	2023-07-30 18:25:44 +02:00
apio	fb08594a18	kernel: Separate FileDescriptors and OpenFileDescription ... Also, add a did_close() callback for OpenFileDescriptions losing all their references.	2023-07-30 11:33:06 +02:00
apio	11df5a2ec3	kernel: Use pid_t internally for process IDs ... This removes a bunch of casts between pid_t and u64, and makes more sense since pid_t is literally the data type for process IDs.	2023-07-26 21:32:00 +02:00
apio	7328cfe734	kernel: Add basic process groups	2023-07-11 11:51:07 +02:00

apio	5e564e9ae3	kernel: Move Thread::self_directory to UserVM ... Since this is only used by user threads, UserVM is a convenient/related place to store the PageDirectory in a RAII manner.	2023-07-09 20:32:42 +02:00
apio	e9e7b22323	kernel: Separate a thread's page directory into two ... The self directory, and the active directory. The active directory is the one the thread is currently using, and the self directory is the one the thread owns. This lets us keep track of both, which fixes ext2 executables crashing the system.	2023-06-25 20:35:40 +02:00
apio	b7bdec9ece	kernel: Add a bunch more config definitions and hide debug messages behind them	2023-06-18 20:18:00 +02:00

apio	2d30935fdb	kernel: Give each thread a working directory	2023-04-11 22:14:57 +02:00
apio	3887b98a7d	kernel: Support setuid binaries ... You still have to run "chmod 4755 /bin/su" as root inside Luna for now, as this is not done by the install scripts.	2023-04-08 16:32:56 +02:00
apio	f6f9254eb4	kernel: Add process and filesystem UIDs and GIDs	2023-04-08 13:12:49 +02:00

apio	0de41410c6	kernel: Use path as the new process name instead of argv[0]	2023-03-24 21:26:45 +01:00
