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	28dd8194af	kernel: Include waited-for grandchildren in RUSAGE_CHILDREN's times	2023-07-25 17:50:15 +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	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	8066e8f1d8	kernel+libc: Implement sigprocmask() and friends	2023-07-10 21:01:59 +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	bdcb690a7a	kernel: Avoid processing unregistered signals for init	2023-07-10 19:48:46 +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
