From 06eec88bb75c870635955d33fd655adfbee49dfa Mon Sep 17 00:00:00 2001 From: Travis Snoozy Date: Sat, 25 Mar 2023 17:56:48 -0700 Subject: [PATCH] Tell dnsmasq not to pass requests upstream The behavior of dnsmasq changed in version 2.86 -- before then, if a record was set for a domain name with dnsmasq, and a record for a type not specified for that domain was requested, dnsmasq would indicate no data existed for that record type. After 2.86, record types that are not specified are instead passed upstream. The latter behavior causes problems for, e.g., the Steam client, which will disregard a correctly set A-record for lancache.steamcontent.com, if no AAAA is set with dnsmasq and dnsmasq passes the AAAA query upstream. The documentation for dnsmasq indicates the correct way to restore the old behavior is to use the local=/host/ syntax -- emit this syntax for each of our lancache-hosted DNS entries. --- scripts/create-dnsmasq.sh | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/scripts/create-dnsmasq.sh b/scripts/create-dnsmasq.sh index 756cf2a..cc6d27a 100755 --- a/scripts/create-dnsmasq.sh +++ b/scripts/create-dnsmasq.sh @@ -52,10 +52,12 @@ while read -r entry; do fi parsed=$(echo ${fileentry} | sed -e "s/^\*\.//") for i in ${cacheip}; do - if grep -qx "address=/${parsed}/${i}" "${outputfile}"; then - continue + if ! grep -qx "local=/${parsed}/" "${outputfile}"; then + echo "local=/${parsed}/" >> "${outputfile}" + fi + if ! grep -qx "address=/${parsed}/${i}" "${outputfile}"; then + echo "address=/${parsed}/${i}" >> "${outputfile}" fi - echo "address=/${parsed}/${i}" >> "${outputfile}" done done <<< $(cat ${basedir}/${filename} | sort); done <<< $(jq -r ".cache_domains[${entry}].domain_files[$fileid]" ${path})
