37 hourskernel: proc: Do not introduce fork()mainIan Moffett
Simplicity is divine, fork() may be powerful but is no longer simple. It became a thing in the late 70s during the early days of UNIX when computing was simple, when CPUs were only 16-bits, MMUs were not prevalent and RAM was only 512 KB. However it isn't 1971 anymore, process management, CPUs and memory architecture has advanced significantly since. This commit ceases work on the fork() syscall as implementing it would only introduce unnecessary complexity, security issues, hefty processing overhead and would perpetuate what should now be considered legacy. The current best alternative would be providing a form of process spawning as well as a mechanism to wait for the child process to complete. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel: fs: Introduce ctlfsIan Moffett
ctlfs (Control FS) is a filesystem aimed to provide configuration of devices separate from their respective devices files. Most UNIX-like systems rely on the ioctl() mechanism for sending commands to device drivers, while this certainly works, it is important to realize how messy it can get doing all of this through a single interface. ctlfs fixes this by giving each device a "node" in ctlfs that contains several control files. For example, imagine we have a SCSI device (/dev/sd1). Its ctlfs counterpart would be a directory at /ctl/sd1/. For an hdd this may contain files such as: /ctl/sd1/bsize # Block size if read (mode [rwx]: -w-) /ctl/sd1/cmd # Command if written, status if read (mode [rwx]: rw-) ... et cetera Signed-off-by: Ian Moffett <ian@osmora.org>
