setpriv on Linux supports Landlock.
Another example:
$ setpriv \
--landlock-access fs \
--landlock-rule path-beneath:execute,read-file:/bin/ls-static \
--landlock-rule path-beneath:read-dir:/tmp \
/bin/ls-static /tmp/tmp/xorg.atom
The first argument --landlock-access fs says that nothing is allowed.
--landlock-rule path-beneath:execute,read-file:/bin/ls-static says that reading and executing that file is allowed. Itâs a statically linked ls program (not GNU ls).
--landlock-rule path-beneath:read-dir:/tmp says that reading the /tmp directory and everything below it is allowed.
The output of the ls-static program is this line:
ârwârâârââââx 3000 200 07-12 09:19 22'491 â /tmp/tmp/xorg.atom
It was able to read the directory, see the file, do stat() on it and everything, the little x indicates that getting xattrs also worked.
3000 and 200 are user name and group name â they are shown as numeric, because the program does not have access to /etc/passwd and /etc/group.
Adding --landlock-rule path-beneath:read-file:/etc/passwd, for example, allows resolving users and yields this:
ârwârâârââââx cathy 200 07-12 09:19 22'491 â /tmp/tmp/xorg.atom
The Linux installation on my main PC turned 14 today:
$ head -n 1 /var/log/pacman.log

This is just a test.
Yep!

Over the past few weeks I've been experimenting with and doing some deep learning and researching into neutral networks and evolutionary adaptation of them. The thing is I haven't gotten very far. I've been able to build two different approaches so far with limited results. The frustrating part is that these things are so "random" it isn't even funny. Like I can't even get a basic ANN + GA to evolve a network that solves the XOR pattern every time with high levels of accuracy. đ

10 Most Devastating Computer Viruses
Long before computers made their way into workplaces and homes everywhere, people theorized about a destructive kind of program that could replicate itself and spread between networked machines. In the 1980s and early 1990s, those programs became popularly known as âcomputer viruses.â Youâve probably had one at some point. All it takes is one wrong [âŚ]
