Fix the size check added to dns_resolver_preparse() for the V1 server-list header so that it doesn't give EINVAL if the size supplied is the same as the size of the header struct (which should be valid).
This can be tested with:
echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @pwhich will give "add_key: Invalid argument" without this fix.

Your (follow-up) patch is now upstream.
https://git.kernel.org/linus/acc657692aed438e9931438f8c923b2b107aebf9
This misses CC: Stable Tag as suggested by Linus.
Looks like linux-6.1.y and linux-6.6.y needs it, too.

And 5.10.y and 5.15.y. Now queued up, thanks.
