2022-05-02meta: write a script to generate `src/init/syscalls.c`dzwdz
2022-05-02syscalls: fork() noreap flagdzwdz
2022-05-02kernel/vfs: pass `close()` calls to fs handlersdzwdz
2022-04-14kernel: port init's `printf` implementationdzwdz
2022-04-12kernel: make all sizes unsigned, sort out the sign messdzwdz
2022-04-10kernel/driver: modify the ps2/serial drivers to use ring_tdzwdz
2022-04-10shared: implement a basic ring bufferdzwdz
2022-03-27shared/memcpy: copy in 4byte blocksdzwdz
2022-03-27shared/syscalls: change some pointer types to void*dzwdz
2022-03-06shared: add strcmp() testcases, fix invalid implementationdzwdz
2021-11-26shared: move `enum vfs_operation` to types.hdzwdz
2021-11-20kernel: fs_wait returns a success val; the op type is put in the structdzwdz
2021-11-16kernel/vfs: add a capacity field to fs_wait_responsedzwdz
2021-11-14shared: move the str* implementations to shared/mem.cdzwdz
2021-11-14shared: use a single implementation of mem* functions everywheredzwdz
2021-11-02fork2() refactor: implement fs_fork2()dzwdz
2021-11-02fork2 refactor: every process now has (only) a single controlled vfs_backenddzwdz
2021-10-04remove support for processes returning strings on exitdzwdz
This isn't really all that useful, it doesn't enable anything that wasn't possible before. With it removed I'll be able to implement process_exit() in a much simpler way.
2021-09-21add `__force` for marking casts across adress spacesdzwdz
2021-09-20add an offset parameter to read() and write()dzwdz
2021-09-20use a single struct for all fs_wait return valuesdzwdz
2021-09-18put the `handle_t` typedef in `shared/types.h`dzwdz
2021-09-18merge `kernel/types.h` and `init/types.h`dzwdz
2021-09-16fs_read stub, basic implementation in userlanddzwdz
2021-09-15fs_wait: pass the file ID toodzwdz
2021-09-14merge the `syscall_handler` and `_syscall` declarationsdzwdz
i think that making the call a bit more "transparent" makes the code nicer
2021-09-12simplify `fs_respond`'s signaturedzwdz
2021-09-12move `enum vs_operation` to shared/flags.hdzwdz
2021-09-12implement part of `fs_respond`dzwdz
2021-09-12barebones `memflag()` implementation - letting the user allocate pagesdzwdz
2021-09-12remove `shared/vfs.h`, it was unuseddzwdz
2021-09-12implement most of fs_waitdzwdz
awaited_req is a garbage name but i couldn't come up with a better one. i also have no idea how to handle all the failure states
2021-09-11replace `user_ptr` with a linux-style `__user` annotationdzwdz
2021-09-09basic _syscall_fs_wait() impl, doesn't pass the req yetdzwdz
2021-09-08copy _syscall_fs_open's argument to a new buffer instead of a shared onedzwdz
this will be needed for storing vfs_op's properly
2021-09-07implement fs_create(), front/back fs handlesdzwdz
2021-09-05error out when <*/types.h> isn't included in headers which need itdzwdz
2021-09-05remove the fd_ / fs_ prefixes from syscall namesdzwdz
2021-09-05root vfs: implement writing to /ttydzwdz
2021-09-04new vfs impl pt. 1: implement open()dzwdz
2021-09-04rename file descriptors to handlesdzwdz
2021-08-25remove FD_STDOUTdzwdz
init can just open `/tty` instead
2021-08-25change the signature of _syscall_fd_mountdzwdz
2021-08-24switch to using user_ptr for pointers coming from userlanddzwdz
this avoid accidental dereferences, and now it's easy to tell apart which pointers are safe to directly read and which aren't. cons: - const is completely discarded
2021-08-24replace () with (void) in function definitionsdzwdz
`()` means that any amt of arguments will be accepted, which isn't what i want
2021-08-24move syscalls.h to shared/syscalls.hdzwdz
2021-08-24implement FD_SPECIAL_TTY, an stdout equaliventdzwdz
