<pre>Hi,
meta skuid datatype is a 32-bits unsiugned integer:
# nft describe meta skuid
meta expression, datatype uid (user ID) (basetype integer), 32 bits
not a boolean type.
<span class="quote">> According to the nft(8) man page (<a href="https://man.archlinux.org">https://man.archlinux.org</a>
> /man/nft.8.en#BOOLEAN_TYPE), it is possible to only check the existence of
> `fib`, `exthdr`, and `tcp option` of a packet.</span >
Yes, these selector might return a boolean, but not meta skuid.
What is the intention? Are you aiming at checking if the skbuff is attached to
a socket?</pre>
