Bananymous 2424f38a62 Userspace: Implement super simple DNS resolver in userspace 
You connect to this service using unix domain sockets and send the
asked domain name. It will respond with ip address or 'unavailable'

There is no DNS cache implemented so all calls ask the nameserver.

Bananymous 862993398d AOC2023: Implement day12 
There seems to be a problem with my malloc so the hash map is not
working. This code worked fine on my linux with actually working
malloc :D

Bananymous 58633ca373 AOC2023: Remove unnecessary loop 2023-12-10 20:18:59 +02:00
Bananymous 00d57d783e LibC+userspace: Make everything compile with -Wall -Wextra -Werror 
I added -Wall -Wextra -Werror as public compile flags to libc. Now
everything in userspace in compiled using these flags. I made all
necessary changes to allow compilation to work.

Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.

Bananymous b523ccb893 AOC2023: Implement day8 
Second part was kinda weird. You are supposted to assume something
of the input, which necessarily is not true.

Solution to second puzzle is not optimal, it definately should be
O(1) space, but I didn't want to think about it.

Bananymous ff550785a7 Userspace: Implement basic image rendering for Netbpm

Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.

Bananymous 07f8c972b3 Shell: Set get old termios earlier 
I sourced the config file before getting old termios. Sourcing
updated the termios so old_termios was always in non canonical, non
