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	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	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	d27ffce5db	kernel: Move the signal handling logic to after a syscall sets its return value ... When a signal was caught after a syscall, it was doing so without preserving the return value of the syscall.	2023-07-12 13:34:30 +02:00
apio	69f9701097	kernel+libc: Implement isatty()	2023-07-11 12:05:09 +02:00

apio	c599251d2a	kernel: Rename UserVM to AddressSpace ... This is a more appropriate name now that it does more stuff than allocate virtual memory. To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess.	2023-07-09 20:38:04 +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	77686b26f8	kernel/Ext2: Read the root inode metadata from the disk	2023-06-25 20:35:36 +02:00
