In the nft_meta_set_eval, nftrace value is dereferenced as u32 from sreg.
But correct type is u8. so that sometimes incorrect value is dereferenced.
Steps to reproduce:
%nft add table ip filter
%nft add chain ip filter input { type filter hook input priority 4\; }
%nft add rule ip filter input nftrace set 0
%nft monitor
Sometimes, we can see trace messages.
trace id 16767227 ip filter input packet: iif "enp2s0"
ether saddr xx:xx:xx:xx:xx:xx ether daddr xx:xx:xx:xx:xx:xx
ip saddr 192.168.0.1 ip daddr 255.255.255.255 ip dscp cs0
ip ecn not-ect ip
trace id 16767227 ip filter input rule nftrace set 0 (verdict continue)
trace id 16767227 ip filter input verdict continue
trace id 16767227 ip filter input

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
