Hey there!
If you're thinking of working on Lix, please consider talking to us about it!
You should be aware that we are ${sgr}1mnot${sgr}0m accepting major features without some conditions,
and we highly recommend looking at our freeze status page on the wiki:
${sgr}32m${freezePage}${sgr}0m
We also have an overview of the codebase at
${sgr}32m${codebaseOverview}${sgr}0m,
and other helpful information on the wiki.
But above all else, ${sgr}1mwe want to hear from you!${sgr}0m
We can help you figure out where in the codebase to look for whatever you want to do,
and we'd like to work together with all contributors as much as possible.
Lix is a collaborative project :)
You can open an issue at https://git.lix.systems/lix-project/lix/issues
or chat with us on Matrix: #space:lix.systems.

The Lix style guide requests that header files: - Begin with `#pragma once` so they only get parsed once - Contain a doxygen comment (`/**` or `///`) containing `@file`, for example, `///@file`, which will make doxygen generate docs for them. When adding that, consider also adding a `@brief` with a sentence explaining what the header is for.

libstore/build: use an allowlist approach to syscall filtering Previously, system call filtering (to prevent builders from storing files with setuid/setgid permission bits or extended attributes) was performed using a blocklist. While this looks simple at first, it actually carries significant security and maintainability risks: after all, the kernel may add new syscalls to achieve the same functionality one is trying to block, and it can even be hard to actually add the syscall to the blocklist when building against a C library that doesn't know about it yet. For a recent demonstration of this happening in practice to Nix, see the introduction of fchmodat2 [0] [1]. The allowlist approach does not share the same drawback. While it does require a rather large list of harmless syscalls to be maintained in the codebase, failing to update this list (and roll out the update to all users) in time has rather benign effects; at worst, very recent programs that already rely on new syscalls will fail with an error the same way they would on a slightly older kernel that doesn't support them yet. Most importantly, no unintended new ways of performing dangerous operations will be silently allowed. Another possible drawback is reduced system call performance due to the larger filter created by the allowlist requiring more computation [2]. However, this issue has not convincingly been demonstrated yet in practice, for example in systemd or various browsers. To the contrary, it has been measured that the the actual filter constructed here has approximately the same overhead as a very simple filter blocking only one system call. This commit tries to keep the behavior as close to unchanged as possible. The system call list is in line with libseccomp 2.5.5 and glibc 2.39, which are the latest versions at the point of writing. Since libseccomp 2.5.5 is already a requirement and the distributions shipping this together with older versions of glibc are mostly not a thing any more, this should not lead to more build failures any more.
