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	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	5aad7d3154	kernel/x86_64: Fail on invalid interrupts instead of calling FIXME_UNHANDLED_INTERRUPT ... A FIXME is something that should be changed later, this is a check for something that should never happen.	2023-07-25 18:23:33 +02:00

apio	105ed79f8f	kernel: Reenable userspace stack tracing, but hidden behind a config flag ... Sometimes this is needed for userspace program debugging (such as ports), but sometimes it can crash, so we leave it off by default.	2023-07-25 17:02:09 +02:00
apio	ad3f3bf4db	kernel: Log the release name and build date in the boot log	2023-07-24 11:48:01 +02:00

apio	36a74fd8d6	kernel/x86_64: Provide an alternate kernel stack for exceptions ... This avoids stack-related triple faults, hopefully. Closes #33.	2023-07-21 15:14:52 +02:00

apio	de6fe7f7c2	kernel+libc+sh: Make the TTY device actually follow termios rules ... Like, so much more termios compatibility!	2023-07-13 20:33:20 +02:00
apio	efd5bae7a5	kernel: Implement querying the terminal window size	2023-07-12 22:09:28 +02:00
apio	546d900454	libc+apps: Start implementing POSIX-compliant termios.h wrappers around tty ioctls	2023-07-12 19:23:06 +02:00
apio	5f698b4774	kernel: Don't create a new kernel stack on exec() ... The old one was not getting freed, creating a memory leak every exec(), which can get huge over time. Plus, there was no need for a new stack. And we couldn't just free the old one, since sys_execve() runs on the old stack...	2023-07-12 16:06:56 +02:00
apio	f629e17ff4	kernel/x86_64: Only show kernel addresses in backtraces ... This avoids walking off into userspace memory where we don't know what could happen.	2023-07-12 16:04:45 +02:00
apio	81e1fdf81e	kernel+libc+login+sh+su: Implement foreground and background process groups in the default console ... Also, the console sends SIGINT to the foreground process group when ^C is pressed!	2023-07-12 13:49:37 +02:00
apio	9f45026cc2	kernel+sh: Implement interruptible syscalls	2023-07-12 13:48:43 +02:00

apio	b64093dee5	kernel+libc: Implement getpgid()	2023-07-12 13:44:25 +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	015419b8f5	kernel: Generate signals when children exit / when faults occur ... Userspace can now catch segfaults!	2023-07-10 20:49:22 +02:00
apio	60d68b74e1	kernel: Define a good set of default signals ... Most of these have POSIX-defined numbers.	2023-07-10 20:30:37 +02:00
apio	cde467ee46	kernel: Support returning termination signals from waitpid	2023-07-10 20:16:06 +02:00
apio	fc3fdc2b87	kernel: Add default actions for signals	2023-07-10 19:59:01 +02:00

apio	15d6aae701	kernel+libc: Implement basic signals	2023-07-10 19:46:57 +02:00
apio	56f3d26969	kernel+libluna: Fix the CRC32 algorithm and use it to verify the GPT header	2023-07-10 14:54:55 +02:00
apio	16b0531d42	kernel+apps+base+tools: Use Ext2 for the root partition file system ... init is now split into two parts: preinit, which lives in the initrd and prepares the root file system for init, and the actual /usr/bin/init, which lives in the root partition and starts services and reaps zombies. The kernel now looks for /bin/preinit instead of /bin/init as the executable for the init process. All configuration files in initrd/etc have been moved to base/etc. (The plan is to have only moon and preinit in the initrd.) Since the current Ext2 implementation is read-only (and it's on a CDROM so it would be read-only anyways), /home/selene is a tmpfs (as well as /tmp), to allow for a writable home directory. The system is slower now, but that's to expect since the Ext2 code doesn't use caching and the ATA code still uses PIO.	2023-07-10 13:05:06 +02:00
apio	40413eee18	kernel: Panic when PID 1 exits/crashes	2023-07-10 13:04:47 +02:00
apio	e3552d9df0	kernel: Log hostname changes	2023-07-10 13:04:40 +02:00
apio	a1b92fcc3f	kernel: Add the MOUNT_DEBUG flag	2023-07-10 13:04:34 +02:00
apio	0b488c1232	kernel: Actually use config.cmake ... Looks like file(EXISTS) needs a full path.	2023-07-10 13:04:26 +02:00
apio	b920ffee42	kernel: Don't use an active directory for the idle thread ... Just take the currently used directory.	2023-07-10 13:04:18 +02:00
apio	503dc72686	kernel: Set kernel threads' initial active directories to avoid taking the first directory they use ... This ends up being init's directory, which is fine when init's directory doesn't change... but a little less fine when the init process calls exec()... which is what it does in the new configuration I'm testing...	2023-07-10 13:04:00 +02:00
apio	7908c5a63e	kernel/ATA: Do not discard the controller if at least one channel initialized properly ... This was causing problems in VirtualBox.	2023-07-10 13:01:43 +02:00
apio	ae0cd155c3	kernel: Fix AddressSpace's move assignment operator	2023-07-09 20:43:03 +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	af26dce038	kernel: Zero physical frames instead of virtual pages ... The memset() happens a bit earlier, and we don't have to remap the mapped virtual memory.	2023-07-04 00:49:26 +02:00
apio	3b1219ecf2	kernel/ext2: Make the inner extended superblock struct packed as well	2023-07-02 19:50:27 +02:00
apio	bd757d204e	kernel+libos+libluna: Avoid copying and reallocation when creating Strings ... This is done by reusing the existing buffers in Vector and Buffer instances.	2023-07-02 19:30:25 +02:00
apio	d363d5e915	kernel/ext2: Make sure we don't crash when accessing the last inode	2023-07-02 17:30:14 +02:00
apio	dd914b16d1	kernel: Stop showing memory stats at boot ... No userspace interface yet, but this can be shown using Shift+Ctrl+M.	2023-07-02 16:02:38 +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	5f4103251a	kernel: Preserve the new page directory while exec() is running	2023-06-25 20:35:40 +02:00
