I would like to remind you that reports are published on a quarterly basis and are usually collected during the last month of each quarter, You are also welcome to submit them even earlier if you want, and the earlier you submit them, the more time we have for reviewing. Status report submissions do not need to be very long. They may be about anything happening in the FreeBSD project and community, and they provide a great way to inform FreeBSD users and developers about work that is underway or has been completed. Report submissions are not limited to committers; anyone doing anything interesting and FreeBSD related can -- and should -- write one! The following methods are available to submit your reports: * submit a review on Phabricator and add the group "status" to the reviewers list. You should put your reports in the directory doc/website/content/en/status/report-2024-04-2024-06/ (create it if it is missing); * submit a pull request at . You should put your reports in the directory doc/website/content/en/status/report-2024-04-2024-06/ (create it if it is missing); * send an email to status-submissions@FreeBSD.org including your report. An AsciiDoc template is available at . We look forward to seeing your 2024Q2 reports!

Hello,
 
At my company, we are working on a generic mac module=
=2E Its purpose is to grant some users a set of privileges in order to run =
their services.
For example, it can be configured in order to allow t=
he ntp user to set the system clock (PRIV_CLOCK_SETTIME), or allow a proces=
s to change its user or groups (PRIV_CRED_SET[UID|GID|GROUPS), restricting =
them to some allowed values.
After reading the discussions around the mac_do modul=
e, I was wondering if other people could be interested in such a more gener=
ic module.
Even though it doesn't do the exact same thing, it st=
ill has a lot in common with mac_do while extending its capabilities.
 
So far, it is still a work in progress so we don't ha=
ve code to share yet. Though I think it'd be interesting to speak about the=
 idea.
I can explain further how we plan to do this if any o=
f you is interested.

This sounds a bit like the Solaris RBAC/privileges.

IMO it would be worth to include, as it allows a more fine grained acces= s to privileged stuff without the need to handout full root permissions to = some applications.

That would be copy_file_range(), but as on Linux, it does only offer any benefit on filesystems that support copy-on-write or potentially on network attached storage. NFSv4 has recently gained support for server-side copies if copy_file_range is used, for example. But UFS will fall back to a normal copy operation. ZFS should do this via block cloning, but that has not been enabled by default, since it has a history of corrupted files (and it is not clear, whether all border cases are covered in the latest version).

Note that there is no in-kernel fallback path for if the file descriptor typ= e does not support it. This means that you cannot use it, for example, for c= opies from an anonymous shared memory object to a regular file.

As you can find, FreeBSD cal(1) man page says that "It is not possible to display Monday as the first day of the week with cal". But daily it is more comfortable if weeks start from Monday. I know that there is ncal (vertical) mode which always starts from Monday, but any other calendar in the world (software or that on the wall) is horizontal, so ncal is uncomfortable too. So I've made a simple patch that adds -M option to cal(1) to start week from Monday: https://codeberg.org/vall/stuff/src/branch/main/ncalfixed By the way, Debian also has set of patches that adds such option: https://salsa.debian.org/meskes/bsdmainutils/-/tree/master/debian/patches Can I ask if such an option can be added to the FreeBSD base? It's highly appreciative if my tiny patches with or without modifications can be helpful. Or are there historical or some other reasons for nonpossibility to start weeks from Monday? Thank you! ----- Best regards, Valentine Astakhov.

Imagine the situation when there is a process that is running in the terminal and periodically printing something related to its progress.

At some point this terminal output should be replaced by a TUI in the same terminal that would capture the original process' output and show it in its TUI sub-window, and would also show some other info.


There is the project for Linux called "redirect" that does such stdout/stderr redirection: https://github.com/jerome-pouiller/= reredirect/

However, it uses ptrace functions that are missing in FreeBSD, like PTRACE_POKEUSER.


Is it possible to perform the action like is described in the first paragraph in some other way, given that ptrace doesn't have required functions?


This function is useful in many business contexts, when users run some long-running tools, and there is a variety of ways how results of these tools can be displayed to the user.


Look at the snp device and watch. They are cl= ose if a tty is involved.

They are close if a tty is involved. snp watches, it does not redirect. I suspect that an example almost identical by its main idea is reptyr. AFAIR the program does the same hacking on the target process, by attaching to it, and injecting the code to execute. See ports sysutils/reptyr, I believe that the FreeBSD port was done by kevans.
