| 2022-08-12 | kernel/proc: don't expose internal fuctions, clean up api | dzwdz | |
| 2022-08-12 | vfs: OPEN_RO flag, read-only whitelist entries | dzwdz | |
| 2022-08-11 | kernel/syscalls: merge a few syscalls into vfsop_simple | dzwdz | |
| Those had a lot of repeating code, but I'm not sure if this is the right change. Well, apart from making pipe_joinqueue more consistent. | |||
| 2022-08-11 | kernel: reformat the _syscall dispatch function to a syscall/line | dzwdz | |
| 2022-08-11 | vfs: support for removing files | dzwdz | |
| 2022-08-08 | user: separate tmpfs into its own executable, add `mount` | dzwdz | |
| 2022-08-05 | add _syscall_getsize | dzwdz | |
| 2022-08-05 | move path_simplify to shared code, move its tests to userland | dzwdz | |
| 2022-08-04 | do some simple TODOs, organize the rest; general code maintainance | dzwdz | |
| 2022-08-04 | syscalls: add _syscall_sleep() | dzwdz | |
| 2022-07-29 | syscall/write: WRITE_TRUNCATE | dzwdz | |
| 2022-07-29 | syscall: up the max argument count to 5; make write accept flags | dzwdz | |
| 2022-07-26 | shared: move some headers from shared/ to camellia/ | dzwdz | |
| 2022-07-20 | user/elf: free memory not belonging to the elf when jumping to it | dzwdz | |
| 2022-07-18 | syscalls: implement execbuf | dzwdz | |
| i have been planning to implement something like this for a while now. it should be faster when doing consecutive syscalls (to be tested). it will also be helpful in writing the elf loader | |||
| 2022-07-17 | kernel/virt_cpy: error struct, better error handling | dzwdz | |
| 2022-07-16 | amd64: back at the shell! | dzwdz | |
| 2022-07-16 | amd64: init can print to the terminal now | dzwdz | |
| 2022-07-16 | amd64: seemingly working syscalls (SYSCALL/SYSRET) | dzwdz | |
| 2022-07-10 | syscalls: implement dup | dzwdz | |
| 2022-07-09 | syscalls/pipe: turn into a POSIX-style api with separate rw ends | dzwdz | |
| Without separate read/write ends you can't tell when there are no more writers left if you have multiple readers. Consider this piece of code: int fd = pipe(); fork(); // execution continues in 2 processes while (read(fd, &some_buf, sizeof somebuf) >= 0) { ... } Once both processes call `read()`, it's obvious that no writes are possible - all the processes that hold a reference to the pipe are currently stuck on a `read()` call, so the kernel could just make it return an error in both. But, what then? It's still possible to write to the pipe, and you can't know if the other process will do that. Thus, if you don't want to miss any output, you have to keep reading the pipe. Forever. Both processes end up stuck. Having separate read/write ends prevents that. | |||
| 2022-07-08 | kernel/proc: remove the type argument from process_handle_get | dzwdz | |
| 2022-07-08 | kernel/syscalls: fix the SYSCALL_RETURN macro for returning pointers | dzwdz | |
| 2022-07-08 | syscall/fs_respond: get the file id from the buf argument | dzwdz | |
| Previously, file ids could only be positive integers, so their range was 31 bits - not enough to represent the entire memory. Now, pointers can be safely used as file ids. | |||
| 2022-07-07 | kernel/vfs: delegate support in _syscall_fs_respond! | dzwdz | |
| this is big in terms of speed, it avoids a lot of unnecessary context switches | |||
| 2022-07-07 | shared: add a flags argument to _syscall_fs_respond | dzwdz | |
| 2022-07-06 | kernel: don't panic on nonexistent syscalls | dzwdz | |
| 2022-07-06 | kernel/pipes: read & write support | dzwdz | |
| 2022-07-05 | kernel: initial partial pipe support | dzwdz | |
| 2022-07-01 | kernel: disable klog | dzwdz | |
| 2022-07-01 | kernel: add the debug_klog syscall for tracking down process ids | dzwdz | |
| 2022-06-29 | kernel/vfs: add the OPEN_CREATE flag | dzwdz | |
| 2022-05-26 | kernel/style: don't return pointless values in _syscall | dzwdz | |
| 2022-05-26 | syscalls/memflag: FINDFREE flag | dzwdz | |
| 2022-05-21 | kernel/i386: only map what's absolutely necessary in the user | dzwdz | |
| 2022-05-21 | syscall/memflag: zero out allocated pages to prevent leaks | dzwdz | |
| 2022-05-21 | syscall/memflag: implement freeing memory | dzwdz | |
| 2022-05-15 | syscall/await: ensure the children are reapable before hanging | dzwdz | |
| 2022-05-15 | kernel/syscall: ensure SYSCALL_RETURN value is used | dzwdz | |
| 2022-05-15 | kernel/mem: remove virt_cpy2kmalloc | dzwdz | |
| 2022-05-06 | kernel: remove the union in `struct handle` | dzwdz | |
| 2022-05-06 | syscalls: merge fork() and fs_fork2() | dzwdz | |
| 2022-05-06 | kernel/proc: reorganize the functions | dzwdz | |
| 2022-05-06 | kernel/proc: get rid of the PS_DEADER state, free processes asap | dzwdz | |
| 2022-05-05 | kernel: each driver registers its own mounts | dzwdz | |
| 2022-05-05 | kernel: syscalls now have to explicitly save the return value | dzwdz | |
| thus they can opt out of doing that so the calls which might return immediately but can return later don't have to both regs_savereturn and return to the caller. and because of that, the return values of a lot of VFS things have just got way saner | |||
| 2022-05-05 | kernel: move the COM1 driver to a separate handler | dzwdz | |
| 2022-05-05 | kernel/vfs: refactor vfs_backend to allow multiple kernel backends | dzwdz | |
| 2022-05-05 | kernel/vfs: rename the vfsreq funcs, merge vfsreq_finish & vfsreq_cancel | dzwdz | |
| 2022-05-04 | kernel: refcount vfs_backend | dzwdz | |
| what a mess | |||
